Description

Plant fiber blended fabric and processing method thereof

Technical Field

The invention relates to the technical field of textile processing, in particular to a plant fiber blended fabric and a processing method thereof.

Background

In daily wear of people, except a small amount of clothes made of natural fibers such as cotton, hemp, silk and wool, the majority of clothes are made of chemical fibers made of chemical synthetic high molecular compounds, such as polyamide cellulose (nylon), polyester fibers (terylene), polyacrylonitrile fibers (acrylon), polyvinyl formal fibers (vinylon) and the like, and the majority of chemical fibers are organic substances extracted from petroleum and are made into fibers by chemical synthesis and mechanical processing. Chemical fibers, particularly terylene, nylon and the like are widely applied to daily life of clothes, hats, clothes and the like of people. In addition, another expression form of chemical fiber is artificial fiber, which is a general name of a plurality of chemical fibers prepared by directly dissolving some linear natural high molecular compounds or derivatives thereof in a solvent or preparing the linear natural high molecular compounds or the derivatives thereof, dissolving the linear natural high molecular compounds or the derivatives thereof in the solvent to generate a textile solution, and then spinning the textile solution. The fabric comprises three types of rayon, artificial cotton and artificial wool, and the main types of the fabric comprise viscose, acetate, cuprammonium and the like.

Since the end of the 18 th century, chemical synthetic fibers appeared, such as polyester fibers, the chemical fibers have the advantages of excellent performance, wide application, stable quality, good strength and wear resistance, stiff and smooth fabric manufactured by the chemical fibers, difficult deformation and strong heat resistance of terylene; has better chemical stability, and can not react with weak acid, weak base and oxidant at normal temperature. However, the chemical synthetic fiber has a disadvantage of extremely poor moisture absorption, and a fabric woven from the chemical synthetic fiber is stuffy and airproof when worn on a body. In addition, because the surface of the fiber is smooth, the cohesion between the fibers is poor, the frequently-rubbed part is easy to fluff and form balls, and strong static electricity can be generated, so that the application of the fiber in certain fields is limited. Meanwhile, chemical fiber has two fatal weaknesses, so that the chemical fiber is certainly replaced by plant fiber in the future:

1. the chemical synthetic fiber is extracted from petroleum, occupies a great amount of non-renewable underground resources, and the exploitation of the resources is a destruction to future society from the viewpoint of protecting the earth and thinking for the offspring.

2. The chemical synthetic fiber is generally not degradable like plastic, the waste can cause serious environmental pollution to the earth surface, and the only means at present is recycling.

In addition to natural animal and plant fibers such as cotton and hemp, the fiber is used as a novel green fiber such as tencel, modal, bamboo, corn, mugwort, aloe, mint, isatis, and Yasaier, which are newly developed in recent two years. Examples are as follows:

1. tencel (Tencel): belongs to pure natural regenerated fiber, is developed by Acordis corporation of England with 100 percent of natural wood pulp extracted from eucalyptus as raw material and is called the fiber dream of the 21 st century. It is characterized in that: softer feel than real silk; superior moisture absorption than cotton; light and thin, easy to wash and dry. The Tencel has high strength, can be used as industrial fiber, and simultaneously has the comfort of cotton, the hand feeling as real silk and good drapability. Is the only new fiber which integrates the advantages of fiber and natural fiber in the world an ancient type of spoon at present. Tencel causes little pollution to the environment during production and is also called "green fiber in the 21 st century". As soon as Tencel appeared, numerous fabric makers and garment manufacturers who paid attention to the field of new fabric development were attracted, and became fiber names which have been used very frequently recently.

2. Modal fiber: the raw material is produced from shrub forest in Europe, is made into thumb pulp, and is prepared by a special spinning process, and the pulp is a cellulose fiber, so the pulp belongs to the same cellulose fiber as cotton and is a pure natural fiber. Modal products are now used in the production of underwear for their inherent characteristics of good softness and good absorbency but poor fabric stiffness. Modal knitted fabrics are mainly used for making underwear. However, the modal has the characteristics of silver-white luster, excellent dyeability and bright color after dyeing, the modal dry strength is close to the polyester strength (35cn/tec), the wet strength is slightly lower than that of cotton, the polyester fiber is soft and smooth, silky feeling and small in wet elongation, the dry elongation of the fiber is between that of cotton and viscose, and the wet elongation of the fiber is almost as large as that of the cotton but smaller than that of the viscose; the washing shrinkage is low, the moisture absorption capacity is fifty percent higher than that of cotton, and the moisture absorption speed is extremely high. The dyeing property of the modal fiber is that the absorption speed of the modal fiber to the pigment is faster than that of combed cotton, the absorption rate is high, and the dyed color is bright; the air permeability is good. The fine denier modal fiber meets the requirements of the ECO-TEX standard, is physiologically harmless and biodegradable. It is particularly advantageous for textiles that are in direct physical contact with the body, and the fine fibers impart comfortable wear properties to the knit, a soft hand, a runny drape, an attractive shine and high moisture absorption. Because of this, many warp and weft knitting manufacturers have begun to use the fiber as a raw material for producing fashion wear and pajamas, sportswear and sportswear, and also for lace. When the calcium fabric is matched with underwear, the calcium fabric has a particularly ideal effect, so that the skin of a user can always keep dry and comfortable feeling, and the user can still keep water absorption and light and soft feeling even after washing, so that the calcium fabric is completely dependent on the smooth surface of the material, and the fibers of the clothes are prevented from being entangled with each other in the washing process. The modal fiber is taken by the nature and then can return to the nature through biodegradation in the nature, and the green, environment-friendly and regenerative characteristics of the modal fiber are fully embodied.

3. Bamboo fiber yarn: the raw materials are southern high-quality wild moso bamboo fibers, the short yarns produced by using bamboo pulp fibers belong to green products, and knitted fabrics and clothes produced by cotton yarns made of the raw materials have unique styles obviously different from cotton and wood cellulose fibers: the blended fabric woven by the yarn has the advantages of wear resistance, no fuzzing, high hygroscopicity, quick drying property, high air permeability and good drapability, and smooth handfeel, so that the cotton fiber is more smooth, and the appearance of the fabric is improved.

4. Moxa fiber: the wormwood fiber has excellent antibacterial effect, wide antibacterial range and high efficacy, the effect is not lost after washing and dyeing for many times, and the wormwood fiber is different from inorganic antibacterial fibers such as silver, copper, zinc and the like in the market and cannot cause metal accumulation harm to the environment and human bodies. The wormwood fiber has good moisture absorption and air permeability, soft hand feeling and comfortable touch feeling, and the prepared fabric is comfortable, smooth and good in drapability.

5. Sarcandra glabra fiber: the plant components have self-heating effect, and the heating effect is obvious; the essence is extracted from the sarcandra glabra, and the essence is natural and harmless, and has herbaceous pharmacology; has antibacterial property; the oval fiber section has silkiness and smooth touch feeling; perfectly combined with various fibers to show the thousands of styles of fabrics; the natural material is sourced, the natural degradation is realized, and the green and low-carbon effects are realized. The sarcandra glabra is a peculiar herbal plant capable of self-heating, and the sarcandra glabra is rich in hydrophilic groups, can lock water molecules in air, and converts kinetic energy into heat energy. Through the perfect combination of the magical property of nature and modern science and technology, the sarcandra glabra becomes unique plant heating fiber, which brings the most suitable wearing experience and puts the sunshine on the body (the average temperature of the sarcandra glabra fabric is raised by 4.8 ℃).

The common characteristics of the plant fibers comprise the following three main aspects:

1. the fibers are all from plants on the earth's surface, that is, as long as air, sunlight and water exist, the fibers are inexhaustible.

2. The plant fibers are all from the nature, can be degraded or recycled, and finally return to be fused with the nature without any damage to the ecological environment on the earth surface.

3. These fibers each have different advantageous properties, and the advantageous combination of fibers results in many advantageous textile effects.

The different proportioning combinations of the cotton, hemp, silk, wool, tencel, Modal, bamboo fiber, corn fiber, and recently developed wormwood fiber, aloe fiber, mint fiber, isatis root fiber and Jacell can make up the defects of respective products, such as poor cotton perspiration, easy wrinkling of clothes, poor bamboo fiber fabric resilience and high tencel price, and different excellent effects can be produced on the fabric through different fiber combinations, so that different wearing requirements of people due to seasonal changes can be met, the fabric and finished clothes are smooth and flat, strong in drapability and excellent in crease-resistant resilience, and the fabric and finished clothes have good texture.

In addition, different spinning modes can bring different performances and effects to the finished fabric product. The spinning methods commonly used in the industry include the following:

1. ring spinning:

ring spinning (ring spinning), the most used and common spinning method in the current market, is widely applied to spinning engineering of various short fibers, such as carding, combing and blending, wherein a fiber strip of drafted slivers or roving is led in by a ring traveler in a rotating way, the winding speed of a bobbin is faster than that of the traveler, and cotton yarns are twisted into spun yarns. The process is as follows: the method comprises the steps of blowing, cotton carding, pre-drawing, sliver doubling and winding, combing, primary drawing, secondary drawing, roving, spinning and winding.

2. Compact spinning, siro spinning, and compact siro spinning:

compact spinning, also known as "compact spinning", is a ring spinning method in which the spun yarn has a relatively compact structure. The width of the fiber strand output by the front roller is gradually contracted to be close to the diameter of the finished yarn by using a gathering device; meanwhile, the twisting action of the steel wire ring is directly reached to the output jaw line of the gathering device, and the condition that edge fibers of ring spun yarns are lost and end fibers are exposed outside the yarn body to form hairiness is completely changed. The spun yarn has compact structure, smooth appearance, higher strength than common ring spun yarn, less filoplume, low twist and better processing performance in the next working procedure.

Sirospun yarn is also called direct twist spinning or double-yarn spinning. The spinning method of spinning yarn, doubling and twisting. Two pieces of rough yarn are fed into a apron drafting device at the same time, and double collectors are arranged behind a rear roller and a front roller, so that the two pieces of rough yarn fed to a person are prevented from being diffused and combined. The fiber strands are respectively output from the front roller, and are converged into the yarn guide hook through the single yarn breaker, and two single yarns are twisted by the twisting winding mechanism of the common ring spinning to form a twisted yarn after being twisted back in the twisting process. If one yarn breaks, the single yarn breaker immediately breaks the other yarn to prevent spinning from lacking. When the spindle rotates, the single yarn and the plied yarn are twisted simultaneously, wherein the plied yarn is twisted firstly, and the generated twisting torque moment is transmitted through the twist degree to ensure that the single yarn also obtains the twist degree until the twisting stress of each section of yarn reaches the dynamic balance). The single yarn twist and the plied yarn twist are in the same direction, and the plied yarn twist is double the single yarn twist. The spun folded yarn is a same-direction plied yarn, and is different from the common ring spun yarn same-direction plied yarn in that two single yarns are weakly twisted, fibers are tightly arranged after plying, the cross section of the yarn is circular, the yarn is thin, the structure is loose inside and stiff outside, the hand feeling is good, and the spun folded yarn is suitable for being made into light and thin fabrics. The siro spinning process is short, the energy consumption is low, the economic benefit is high, and the siro spinning process is suitable for producing finer yarns by wool spinning, but the folded yarns are folded in the same direction, single yarns are not cleared, and the folded yarns are knotted more and the yarn returns more.

Compact siro spinning is to effectively combine the technologies of compact spinning and siro spinning, and a spun single yarn has the advantages of less compact spinning hairiness, high yarn finish degree, good fuzz and pilling resistance, and meanwhile, the single yarn has the effect of double yarns, so the compact siro spinning has good texture. Meanwhile, the compact siro spinning can be spun into 32S-200S single yarn, and is suitable for being used as finished fabrics of underwear, T-shirts, children clothes, bedding and the like.

3. Vortex spinning

The spinning principle of vortex spinning is that sliver which finishes drawing is supplied to a drafting device, fiber bundles drafted by a roller drafting device are output from a front roller jaw and enter a spinning nozzle along a spiral fiber guide channel under the action of axial airflow at the inlet of the spinning nozzle. The outlet of the spiral fiber guide channel is provided with a needle-shaped twist-stopping piece, and the fiber bundle is bent at the needle part, so that the fiber bundle is introduced into the vortex chamber in a state of not adding twist. The leading end of the fiber bundle is drawn into a yarn passage in the spindle by the dragging action of the formed yarn and twisted into the newly formed yarn as a yarn core. The tail end of the fibre remains in the fibre guide channel while being gripped by the front roller nip. When the tail end of the fiber is not held by the front roller jaw any more, the tail end of the fiber is not kept in the fiber guide channel under the centrifugal action of the air vortex in the spinning nozzle, but is radially dispersed by the rotating airflow at the spindle inlet, is laid on the conical surface at the front end of the spindle under the driving of the air vortex, rotates along with the air vortex, is wound on the subsequent yarn and is output through the channel of the yarn in the spindle. The yarn formed is composed of a yarn core formed by approximately parallel untwisted fibers and fibers wrapped spirally on the periphery. The yarn formed and delivered is removed of yarn defects by an electric yarn cleaner and then wound on a bobbin. The fibers themselves receive different loads due to the difference in the sum of the residence time of the fibers in the nozzle and the energy density of the air jet. Thus, the characteristics of the yarn also change. The higher the speed, the softer the yarn and the lower the speed, the stiffer the yarn. Vortex spun yarns have the characteristics of being hard outside and soft inside.

Compared with other spinning modes, the vortex spinning has the following advantages:

1. high speed and high yield

The spinning speed of the vortex spinning machine is 100-200 m/min, and the practical speed is generally 100-160 m/min. Spinning 6-12 English yarns by using a vortex spinning machine at the spinning speed of 100-140 m/min, wherein the single yield is 600-800 (kg/thousand-ingot.h), which is equivalent to 4-5 times of that of ring spun yarns; for example, the output of spinning 40 counts acrylic yarn by using 10 (192 pieces/machine) PF-1 type vortex spinning machines reaches 400 kg/h. The productivity of 20 BD-200 rotor spinning machines is equivalent to that of 40 ring spinning machines 16320 spindles. The throughput of one vortex spinning head corresponds to the throughput of 2.08 air spinning heads or 8.5 ring spindles. Since vortex spinning relies on vortex twisting, spinning speeds can continue to increase as improvements continue to be investigated.

2. Short process flow and high yield

3. The vortex spinning is to directly spin the fiber sliver into cheese, so as to save two procedures of roving and spooling like other novel spinning. Because the end breakage rate of the vortex spinning is very low, the return loss is less, and the finished product rate is up to more than 99%.

4. High spinnability and suitable for making pile product

5. The vortex spinning can spin pure spinning and blended spinning of cotton fibers and chemical fibers with the fiber length of 38-60. The yarn has a bulkier structure, so that the dyeing property, the pulp absorption property and the air permeability are better, and the pilling resistance and the wear resistance of the yarn are also better. The count range of the yarn is only limited to medium and low count yarn, and the yarn is suitable for being used as a napping product. For example, 38-long chemical fibers (acrylic fibers, polyvinyl chloride fibers, viscose, and the like) are spun into 6-12 English yarns, and knitted and napped products such as flannelette, scarf, back cushion, sofa cloth, furniture cloth, tablecloth, and the like are woven.

6. Vortex spinning adopts a vortex tube to form yarns, and the vortex tube is static and has no high-speed rotating part, so that the connector is very convenient and simple, cleaning is not needed after the end is broken, and the working environment is improved. No special requirements on the fore-spinning equipment and the temperature and humidity. The vortex spinning has no high-speed rotating part, so that the lubricating problem of a high-speed bearing is avoided, the loss is low, the noise is low, and the maintenance is convenient.

Production practices have shown that vortex spinning also presents certain limiting factors in the development process:

1. the range of suitable spinning raw materials for vortex spinning is only limited to short chemical fibers and medium-long fibers, and the competitive power in the field of fine yarns is not strong due to the quality of finished yarns.

2. The yarn forming structure of the vortex spinning is loose, the uniformity of long sections is good, the yarn evenness of the formed yarn is generally close to the level of ring yarn, but the thickness unevenness of extremely short sections is more remarkable than that of the ring yarn, but the strength is lower and unstable, and the development of the vortex spinning to the field of fine yarn is limited.

3. Although the air vortex is used for replacing the rotor of the rotor spinning, the problems of abrasion caused by high-speed rotation of the rotor spinning and overlarge bearing load are solved, but the problems of larger centrifugal force and tension caused by the yarn arm formed when the free end yarn tail rotates in the vortex tube at high speed cannot be solved. And thus its spinning speed cannot be developed in a breakthrough manner.

4. The resultant yarn of vortex spinning has too short coagulation process due to poor fiber straightness, so that the structure of the yarn is loose, the strength of the yarn is low, and the product is limited, and is only suitable for chemical fiber raw materials, products with low strength requirements such as spinning thick knitting yarns or thick napped yarns and the like, or core-spun yarns taking filaments as yarn cores. Nevertheless, also with direct sliver-fed vortex spinning, there are conditions and possibilities to achieve a fully automated continuous production line. The method has the unique advantages of eliminating a roving frame, a spinning frame and an automatic winder, reducing the occupied area, the labor and the investment, and further replacing ring spinning and air flow yarns in the field of knitting yarns. Therefore, there is a need for further development to overcome the disadvantages and limitations of the prior art and to provide a novel spinning process with unique features.

Therefore, the most obvious characteristics of the plant fiber vortex spinning are that the surface of the yarn is relatively hard, the strength of the yarn is relatively low, the manufactured fabric is hard to handle, the problem of hard handle is difficult to completely solve even if a softener is added in the dyeing and finishing, the plant fiber compact siro spinning yarn is relatively soft, the strength of the yarn is relatively high, and the manufactured fabric is soft in texture and lacks of stiff bone feeling.

The applicant tries to combine a plant fiber vortex spun single yarn and a plant fiber compact siro spun single yarn into double yarns, a knitted fabric made of the yarns by a weft knitting machine, a flat knitting machine or a warp knitting machine has the stiffness of vortex spun yarns and the softness of compact siro spun yarns, and the two contradictory aspects are organically combined, so that the final fabric plant and clothes such as male and female T-shirts, underwear, sweaters and the like are smooth and stiff, have full texture and excellent shape retention, and have the advantages of wrinkle resistance, smoothness, strong droop feeling and good rebound resilience.

The specific process steps are as follows:

the yarn plus the weaving (weft knitting machine, flat knitting machine and warp knitting machine) and the ready-made clothes (such as T-shirts, underclothes, sweaters and the like) are manufactured, and the ready-made clothes are smooth and stiff, strong in droop feeling, good in shape retention and good in crease resistance and rebound resilience.

In the aspect of weaving, for example, an air jet loom, one plant fiber compact sirospun single yarn is used as a warp yarn, one plant fiber vortex spun single yarn is used as a weft yarn for interweaving, the woven fabric made of the yarn has the stiffness of vortex spun yarn and the softness of the compact sirospun yarn, the two contradictory aspects are organically combined, and the final fabric and clothes, such as four-piece bedding, are soft, smooth, stiff, plump in texture, excellent in shape retention, stiff and smooth in cloth, strong in drooping feeling and good in crease-resistant resilience.

The specific process steps are as follows:

the invention relates to a fabric (a fabric made of an air jet loom, a water jet loom and a rapier loom) and a finished product (home textile products such as bedding, curtains and the like) which are soft, smooth and stiff, have strong droop feeling, good shape retention and good crease-resistant resilience.
