The fabric of bamboo fibre and blend polyester
Technical field
The present invention relates to a kind of fabric, relate in particular to the fabric of a kind of bamboo fibre and blend polyester.
Background technology
Terylene is an important kind in synthetic fiber, is the trade name of China's polyester fiber.It is to take fiber-forming polymer---the polyethylene terephthalate (PET) that p-phthalic acid (PTA) or dimethyl terephthalate (DMT) (DMT) and ethylene glycol (EG) make through esterification or ester exchange and polycondensation reaction as raw material, the fiber of making through spinning and post processing.
The basic composition material of terylene is polyethylene terephthalate, therefore also claim polyester fiber (PET), relative molecular weight is generally in the 18000-25000 left and right.In fact, wherein also have a small amount of monomer and oligomer to exist.The degree of polymerization of these oligomer is lower, with annular form, exists again.Polyethylene terephthalate can be produced Polyethyleneglycol Terephthalate 9BHET by direct esterification by terephthalic acid (TPA) (PTA) and ethylene glycol (EG)) aftercondensated forms.
From the terylene molecular composition, it is consisted of short fat hydrocarbon chain, ester group, phenyl ring, end alcoholic extract hydroxyl group.Except having two end alcoholic extract hydroxyl groups, there is no other polar group in terylene, thereby polyster fibre hydrophily extreme difference.Approximately contain 46% ester group in the terylene molecule, ester group can be hydrolyzed when high temperature, thermal cracking, meets soap solution of alkali, and the degree of polymerization is reduced; Also contain the aliphatic hydrocarbon chain in the terylene molecule, it can make the terylene molecule have certain flexibility, but due in the terylene molecule in addition can not in the rotation phenyl ring, therefore the large molecule of terylene is rigid molecule substantially, strand is easy to keep line style.Therefore, the large molecule of terylene is easy to form crystallization under this condition, therefore the degree of crystallinity of terylene and orientation are higher.
Terylene has following characteristics:
1. intensity is high.Staple fibre intensity is 2.6-5.7cN/dtex, and high-tenacity fiber is 5.6-8.0cN/dtex.Wet strength and dry strength are basic identical.Impact strength is higher 4 times than polyamide fibre, higher 20 times than viscose.
2. good springiness.Elasticity approaches wool, when elongation 5%-6%, almost can recover fully.Crease resistance surpasses other fibers, i.e. fabric wrinkle not, good stability of the dimension.Modulus of elasticity is 22-141cN/dtex, than the high 2-3 of polyamide fibre doubly.Dacron has higher intensity and elastic recovery capability, therefore, and its strong durable, wash and wear.
3. the heat resistance terylene is to make by the melt-spun method, and the fiber after shaping can, again again through heat fused, belong to thermoplastic fibre.The fusing point of terylene is higher, and specific heat is empty and thermal conductivity is all less, thereby the heat resistance of polyster fibre and thermal insulation are wanted height.Best in synthetic fiber.
4. terylene smooth surface, interior molecules is arranged closely.Terylene is to close the best fabric of heat resistance in fine fabric, has thermoplasticity, can manufacture accordion-pleated skirt, and rivel is lasting.
5. ABRASION RESISTANCE is good.ABRASION RESISTANCE is only second to the best polyamide fibre of ABRASION RESISTANCE, all better than other natural fabrics and synthetic fiber.
6. light resistance is good.Light resistance is only second to acrylic fibers.The light resistance of dacron is better, and except poorer than acrylic fibers, its sun-proof ability surpasses natural fabric.
7. corrosion-resistant.But bleach tolerant, oxidant, hydro carbons, ketone, oil product and inorganic acid.Anti-diluted alkaline, be not afraid of mould.Also has stronger anti acid alkali performance, anti-ultraviolet ability.
8. dyeability is poor, but COLOR FASTNESS is good, not fugitive color.
9. the fabric be made into by the ordinary polyester long filament, it is good that its wearability has intensity, the smooth advantage such as well-pressed, quick-drying washable, but exist Boardy Feeling, the shortcoming such as sense of touch is poor, gloss is not soft, gas permeability, hygroscopicity are poor.
10 hygroscopicity are poor, and dress has feeling of oppression and heat, and simultaneously easy static electrification, contamination dust, affect attractive in appearance and comfortableness.Very easily dry after but washing, and wet decline hardly by force, indeformable, good wash and wear performance is arranged.
Bamboo fibre is a kind of natural high polymer processed by the known bamboo of people as a kind of cellulose fibre.Bamboo fibre is because of its macromolecular special construction, and has the health cares such as good supression bacterial growth, absorption peculiar smell, and hygroscopic vapor transmission, biodegradable, is described as the green fiber of new century.
The Lyocell bamboo fibre, claim again the solvent method bamboo fibre, is a kind of regenerated bamboo fiber that the bamboo cellulose pulp adopts Lyocell technique spinning to form as raw material of take.
The common preparation technology of Lyocell bamboo fibre is: the bamboo cellulose pulp directly is dissolved in N-methylmorpholine-N-oxide aqueous solution of (being called for short NMMO), and prepares regenerated celulose fibre by wet spinning.This friendly process has the characteristics such as abundant raw material, simple, the advanced environmental protection of production procedure, good product performance.Being expected to replace gradually with serious pollution traditional fibre cellulose fiber production technology is adhering process.The solvent method bamboo fibre belongs to a kind of of Lyocell fiber, is described as the green fiber of 21 century.Application for a patent for invention prospectus CN101694019A discloses solvent method high-wet-modulus bamboo fiber and preparation method thereof, but produce the discarded object natural degradation of Lyocell bamboo fibre, amine oxide solvent in production process can 99.5% recycling, and free from environmental pollution.
The present invention attempts that particularly Lyocell is bamboo fiber blended with bamboo fibre by adopting terylene, realizes the effect that fabric is antibiotic, and expects by selecting suitable rear Collator Mode further to promote the anti-microbial property of fabric.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is to provide the fabric of a kind of bamboo fibre and blend polyester.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The fabric of a kind of bamboo fibre and blend polyester, weaved and formed by 5-30wt% bamboo fibre and 70-95wt% blend polyester.
The fabric of a kind of bamboo fibre and blend polyester, weaved by 5-30wt% bamboo fibre and 70-95wt% blend polyester, then form through anti-bacterial finish.
Preferably,
Described fabric, weaved by 15-25wt% bamboo fibre and 75-85wt% blend polyester, then form through anti-bacterial finish.
Described anti-bacterial finish step is, under normal temperature in antibiotic finishing solution dipping 10-30 minute, in described antibiotic finishing solution, the antibacterial finishing agent consumption is 0.5-1.5%o.w.f, bath raio is 1:15-1:30.
