Description

Composite Melting-yarn having excellent tactility and melange effect, And Method preparing same}

The present invention relates to a composite fused yarn having excellent tactile feel and melange effect, and more particularly, to a composite fused yarn having improved tactile feel and dyeing properties due to a uniform fusion site of the composite fused yarn and a method of manufacturing the same.

Composite yarns through the method of combining two or more yarns have been developed with a wide range of efforts to combine the advantages of synthetic fibers and the advantages of spinning yarns into one yarn.

Conventionally, composite yarns were manufactured by simply twisting filaments of synthetic fibers and spun yarns of natural fibers. However, many yarn processing techniques have been developed to meet the various needs of consumers and the development of braiding technology gradually.

Korean Patent Laid-Open Publication No. 2001-0063955 discloses a polyester/acetate composite yarn manufactured by air entanglement between an acetate yarn having a fineness of 50 to 100 denier and a polyester non-uniformly drawn yarn. The composite yarn of the present invention is characterized by using acetate, which is a natural fiber, as an effect yarn, and has the advantages of both natural and synthetic fibers by using a conventional polyester fiber for examination, but mixing with polyester fiber, which is a synthetic fiber. There were problems such as fineness, non-uniformity of dyeing in effectors and screening, and problems with poor bulkiness.

In addition, Korean Patent Laid-Open Publication No. 2006-78217, Japanese Patent Laid-Open No. 1025636, and Japanese Patent Laid-Open No. 11181643 disclose a method for manufacturing a polyamide composite yarn. Among them, Korean Patent Publication No. 2006-78217 relates to a method for manufacturing a composite false-twist yarn made of two types of yarn, and in detail, raw nylon FDY (Fully Drawn Yarn) is used as an examination. By using nylon POY (Partially Oriented Yarn), it is described that it provides a composite false-twisted yarn that has a natural appearance like natural fibers due to woven nylon, and excellent sweat-absorbing quick-drying and soft feeling due to nylon of the molded section. However, although the method has excellent bulkiness and touch, it is not possible to expect a natural feeling or color development according to the use of synthetic fibers.

As described above, when partially oriented partially oriented yarn is used to soften the touch of the composite yarn, the dyeing property of the partially oriented partial oriented yarn is unstable. It was difficult to proceed. As the second spinning method, a general filament yarn and partial oriented yarn are used to combine two materials using a wire bridge device using a general combustible machine, and then heat-treat in a heater. . However, when the composite yarn is sacrificed in this way, it is simply imparted by using a wire bridge device, and the loop cannot be expressed on the surface of the yarn, so the feeling of touch is inferior to that of the composite yarn made by using an air textured yarn machine.

However, since it is false twisted while heat-treating in a heater after the composite, the dyeing stability of the composite yarn can be secured, and the material can be sacrificed using a partially oriented yarn, so the turquoise feel can be softened, but a loop is placed on the surface of the composite yarn. Because it cannot be expressed and only crimp is applied, the touch feeling of the composite yarn is much different from the actual feeling of cotton because the touch feeling of the composite yarn is lower than that of the composite yarn, which expresses a cotton feel by expressing a loop on the surface of the composite yarn using an air texture yarn After that, there was a limit to the development of use in general.

In addition, fusion-bonded yarn, which is a form of composite yarn, is a composite yarn having a fused portion by melting a part of the composite yarn through heat treatment.It has a touch and gloss that cannot be expressed as a general composite yarn, but it is difficult to adjust the distance and length of the fused section. There are many limitations to the problem.

The present invention is invented to solve the above problems, and is manufactured through a false twisting process after combining the test and cation flame retardant effect yarn by air entanglement. It is an object of the present invention to provide a method of manufacturing a composite fusion yarn having excellent tactile feel and melange effect capable of adjusting the length of the fused part.

In addition, it is an object of the present invention to provide a composite fused yarn having excellent touch and melange effect in which a melange effect is expressed during dyeing by using a cation flame retardant partially drawn yarn as an effect yarn.

The present invention is a yarn supply step of supplying an elongation of 30-50% examination and a cationic flame retardant partial drawn yarn having an elongation of 100% or more as an effect yarn; A joining step of supplying the screening and effect yarns through an overfeed and joining together by air entanglement; A fusion twisting step of partially fusing and false twisting the screening and effect yarn by heating the laminated composite yarn at 220 to 240°C; It provides a method of manufacturing a composite fused yarn having excellent tactile feel and melange effect, characterized in that it comprises a decomposition step of decomposing the twisted composite yarn.

In addition, it provides a method for manufacturing a composite fused yarn having excellent tactile feel and melange effect, characterized in that the screening and effect yarns are supplied at an overfeed rate of 1.5 to 2.5% in the fusing step.

In addition, it provides a method for manufacturing a composite fusion yarn having excellent tactile feel and melange effect, characterized in that the draw ratio is stretched to 1.05 to 1.2 in the fusion fusing step.

In addition, it provides a method for manufacturing a composite fusion yarn having excellent tactile feel and melange effect, characterized in that the effector and examination weight ratio is 4:6 to 6:4.

In addition, it provides a composite fusion yarn having excellent tactile feel and melange effect, characterized in that produced by the above manufacturing method.

The composite fusing yarn having excellent tactile feel and melange effect according to the present invention as described above has an excellent tactile feel by uniformly interlacing the screening and effecting yarns, and then heat-treating at a high temperature while twisting them to uniformly fuse the entire yarn.

In addition, there is an effect of expressing a melange effect when dyeing by using a cation flame retardant partially drawn yarn as an effect yarn.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in the drawings, the same components or parts represent the same reference numerals as possible. In describing the present invention, detailed descriptions of related known functions or configurations are omitted so as not to obscure the subject matter of the present invention.

The terms'about','substantially', etc. of the degree used in the present specification are used at or close to the numerical value when manufacturing and material tolerances specific to the stated meaning are presented, and are used in the sense of the present invention. To assist, accurate or absolute figures are used to prevent unfair use of the stated disclosure by unscrupulous infringers.

1 is a flow chart showing a process sequence of a composite fusion yarn having excellent tactile feel and melange effect according to the present invention.

The present invention relates to a composite fusion yarn having excellent tactile feel and melange effect, and is manufactured including a yarn supplying step, a braiding step, a fusion twisting step, and a sea twisting step as shown in FIG. 1.

The yarn feeding step, braiding step, fusion fusing step, and sea twisting step are performed as a series of processes.

The yarn supplying step is a step of supplying a test with an elongation of 30-50% and a cation flame retardant partially drawn yarn with an elongation of 100% or more as an effect yarn.

The screening and effecting yarn may be any one of polyamide-based, polyester-based, polyacrylic-based, and polyolefin-based, but it will be preferable to use a polyester-based yarn for dyeing uniformity.

The cationic flame retardant partially drawn yarn may be made of a polyester-based resin in which a copolymer capable of imparting cationic flame retardancy, such as a 5-sodium sulfoisophthalic acid component and a sulfoisophthalic acid component, is copolymerized.

The effect yarn should be partially drawn yarn having an elongation of 100% or more with the yarn being fused in the fusion bonding step after being entangled with the examination in the bonding step.

Since the melange effect may be lowered if the content of either of the screening and effector is increased, it is preferable that the weight ratio between the effector and the screening agent be 4:6 to 6:4.

The braiding step is a step of braiding by air entanglement while supplying the screening and effect yarns as an overfeed, which can be braided by a general air entanglement method, and interlaced yarn (ITY) method or air textured yarn (ATY) You will be able to combine them in a way.

Although the present invention can be combined in a variety of ways, it will be most preferable to use an Air Textured Yarn (ATY) method for uniform entanglement.

The Air Textured Yarn method is a method in which a loop is formed on the fiber surface by continuously spraying the surface of the fiber with high pressure air pressure.In the present invention, the high pressure is sprayed with air pressure while overfeeding and supplying the screening and effect yarn. As a result of the merger, the effectors with high adherence are confounded as if surrounding the examination.

In the consolidation step, the judges and the effectors are supplied at an overfeed rate of 1.5 to 2.5%, and the overfeed rate of the judges and the effectors is supplied with the same overfeed rate, thereby increasing the uniformity of entanglement.

Even if the screening and the effector are supplied at the same overfeed rate, the effector's elongation is high and the confusion is smoothly formed.

The fusion twisting step is a step of partially fusing and false twisting the screening and effect yarns by heating the laminated composite yarn at 220 to 240°C. As the effect yarns, which are partially drawn yarns, are melted, screening and fusion are formed.

In the fusion twisting step, it is preferable to draw at a draw ratio of 1.05 to 1.2, and by stretching at a high temperature, the crystallinity of the screening and effector is improved, and physical properties are improved.

If the draw ratio is less than 1.05, dyeing property and fairness may be deteriorated due to instability of the yarn, and if the draw ratio exceeds 1.2, the uniformity of fusion formation may be lowered due to tension formed on the surface of the composite yarn.

It is preferable that the composite fusion yarn is twisted at the same time as the fusion, and the false twist is twisted at 500-2000 T/M.

If the temperature is less than 220℃ in the fusion bonding step, the melting of the effector may be weak and the formation of the fusion part may not be smooth. If it exceeds 240℃, the melting of the effector may be excessively generated, resulting in excessive fusion with the fusion part. Sexuality may decrease.

The decomposition step is a step of decomposing the twisted composite yarn. By decomposing the twisted composite yarn 100%, a part of the fusion portion is released, thereby expressing a smooth and cool touch.

The winding step of winding the composite yarn may be further performed after the desealing step. The winding step may be carried out as a general winding step.

The composite fusion-bonded yarn having excellent tactile feel and melange effect of the present invention as described above is formed at the same time as fusion bonding and false-twisting in the fusion bonding step after uniform entanglement is formed in the braiding step, and the fusion part where the examination and effector are fused is uniformly generated, and the length of the fused part It would be desirable that the length of the fusion portion is adjusted to 0.1-2 cm.

If the length of the fused portion is less than 0.1 cm, the unique touch of the fused yarn is not expressed, and if the length of the fused portion exceeds 2 cm, it is difficult to form a uniform fused portion, and dyeing uniformity may be deteriorated due to the fused portion.

The composite fusion yarn having excellent tactile feel and melange effect of the present invention in which the fusion part is formed as described above, is expressed by controlling the fusion part to be formed, and the unique touch of the fusion yarn is expressed. The melange effect is expressed by a dichroic effect with different dyeing properties.

Hereinafter, examples of a method for manufacturing a composite fusion yarn having excellent tactile feel and melange effect according to the present invention are shown, but the present invention is not limited to the examples.

Example 1 to 6

Polyester-based filament yarn with elongation was used as an examination, and cationic flame retardant partially drawn yarn was used as an effect yarn.

While supplying the above screening and the effect yarn with the same overfeed, the joining step of joining together by the air texture yarn method was conducted.

While heat-treating the laminated composite yarn, performing a fusion-twisting step of twisting at a twist ratio of 1.1 while twisting at a twist number of 800T/M is performed, and a decomposition step of decomposing 100% of the twisted composite yarn is carried out, and winding, the tactile feel and melange effect according to the present invention The excellent composite fusion yarn was prepared.

Table 1 shows the elongation of the screening and effect yarns used in Examples 1 to 6, the overfeed rate in the braiding step, and the heat treatment temperature in the fusion fusing step.

Comparative example

Polyester-based filament yarn was used as Hyogo yarn with a 40% elongation polyester filament yarn as an examination.

While the test and effect yarn were heat-treated, a fusion-twisting step was performed in which the twisted yarn was twisted at a twist number of 800 T/M while stretching at a stretching ratio of 1.1, followed by a de-twisting step of 100% twisting the twisted composite yarn, and winding it to prepare a composite fused yarn.

Table 1 shows the elongation of the screening and effect yarns used in the comparative example, the overfeed rate in the braiding step, and the heat treatment temperature in the fusion fusing step.

As shown in Table 2, the composite fused yarn having excellent tactile feel and melange effect according to the present invention has a low overfeed rate as in Example 1 and does not form a uniform entanglement so that the touch and dyeability are deteriorated, so that the melange effect is not apparent As in Example 3, when the overfeed rate is high, the yarn becomes unstable, resulting in poor yarn-making processability and low melange effect. Therefore, it would be preferable that the overfeed rate is 1.5 to 2.5%.

In addition, as in Example 4, the heat treatment temperature in the fusion fusing step is too low and the fusion does not proceed smoothly, so that the tactile feel is deteriorated. . Therefore, it would be preferable to perform the fusion fusing step at 220 to 240°C.

In addition, as can be seen through Examples 1 to 3 and Examples 4 to 6, when the weight of the effector increases, the melange effect decreases, and when the content of either of the effectors and the examination increases, the melange effect decreases. Is preferably between 4:6 and 6:4.

In the comparative example, the screening and the effector are performed in the fusion fusing step without confusion, and it can be seen that the length of the fused part is 15 cm, which lowers the dyeing stability and lowers the spinning process.
