The fabric of acid fiber by polylactic and Coolmax fiber blend
Technical field
The present invention relates to a kind of fabric, particularly relate to the fabric of a kind of acid fiber by polylactic and Coolmax fiber blend.
Background technology
Acid fiber by polylactic is a kind of synthetic fiber of fully biodegradable, and it can obtain from cereal.In soil or seawater, can be analyzed to carbon dioxide and water through microbial action after its goods are discarded, during burning, can not poison gas be distributed, can not pollute.It is a kind of ecological fiber of sustainable development.
The raw materials for production lactic acid of acid fiber by polylactic (PLA) is obtained from cornstarch, so also this fiber is called zein fiber.It is native compound common in organism (comprising human body).The PLA of high molecular can be obtained by the chemical polymerization of lactic acid Cyclodimerization thing or the direct polymerization of lactic acid.Be the goods that raw material obtains with PLA, there is good biocompatibility and Bioabsorbable, and well biological degradability, water imbibition, biocidal property, anti-flammability, and in biodegradable thermoplastic polymer material, PLA has best heat resistance.Concrete, as the acid fiber by polylactic acid fiber by polylactic that the Changjiang river chemical fibre Co., Ltd, Jiangyin Gaoxin Chemical Fiber Co., Ltd. etc. produce.
Coolmax fiber is the functional fiber that E.I.Du Pont Company exclusively researchs and develops, and not only unique-four tubuloses of cross sectional shape, be again doughnut, and the tube wall of fiber are also breathed freely.Just because of the unique physical structure of this fiber, result in its moisture absorption, perspire, ventilating performance, namely fabric has good capillary effect.At any time making soaked with sweat on skin can be detached skin, be transferred to web surface thus evaporate rapidly, make skin keep dry and comfortable and comfortable.By comparing of CoolMax functional fiber fabric and other fabric index of aridity, find no matter within short time or long period, the rate of drying of CoolMax functional fiber fabric is all significantly better than other fabric, and the index of aridity of CoolMax functional fiber fabric is almost cotton 2 times.By CoolMax functional fiber application of dress material on denim fabric, its powerful gas permeability and good moisture absorption control, and will the skin of wearer be kept dry, and reduce physical consumption, perspiration is no longer become problem that one is disturbed people.
The present invention attempts by providing a kind of new blended yarn woven fabric, by acid fiber by polylactic and Coolmax fiber blend.
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 acid fiber by polylactic and Coolmax fiber blend.
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A fabric for acid fiber by polylactic and Coolmax fiber blend, is weaved by 20-40wt% acid fiber by polylactic and 60-80wt%Coolmax fiber blend and forms.
Preferably,
A fabric for acid fiber by polylactic and Coolmax fiber blend, is weaved by 20-40wt% acid fiber by polylactic and 60-80wt%Coolmax fiber blend and forms, then form through anti-bacterial finish.
Described anti-bacterial finish step is in antibiotic finishing solution, flood 10-30 minute under normal temperature, and in described antibiotic finishing solution, antibacterial finishing agent consumption is 0.5-1.5%o.w.f, and bath raio is 1:15-1:25.
Described antibacterial finishing agent, be made up of the component of following weight portion: protamine sulfate 5-15 part, 2,4,4 '-three chloro-2 '-dihydroxy diphenyl ether 50-70 part, N, N-bis-(hydroxyethyl) coconut oleoyl amine 5-15 part, hexamethylene 15-25 part.Above-mentioned each component is uniformly mixed, described antibacterial finishing agent can be obtained.
Concrete, in the present invention:
Protamine sulfate, phonetic name: Liusuan Yujingdanbai, English name: ProtamineSulfate, page number: China's coastal port two-742, the sulfate of a kind of alkaline protein extracted in the adaptive suitable fish fresh mature sperm of this strain.By dry product, be white or off-white powder, odorless, has hygroscopicity, soluble in water, is insoluble in ethanol, chloroform or ether.
Irgacare MP, another name: triclosan, triclosan, abbreviation DP300, English name: 5-chloro-2-(2,4-dichlorophenoxy), No. CAS: 3380-34-5.
N, N-bis-(hydroxyethyl) coconut oleoyl amine, No. CAS: 68603-42-9.
Hexamethylene, English name: Poly (hexamethylenebiguanide) hydrochloride, CAS accession number: 32289-58-0.
O.w.f, full name is On weight the fabric, and textile dyeing and finishing term, in weave dyeing and finishing technique, concentration take fabric weight as benchmark, opposed fabric percentage.
Bath raio, liquor ratio, textile dyeing and finishing term, the ratio of fabric and dye liquor in impregnation method.
It should be noted that, in the present invention as nothing explains explanation especially, each raw material is all in content 100%.
In the present invention, breakthroughly by being usually used in medicine, the raw material sulphuric acid nucleoprotamine of food service industry is applied to weaving antibacterial treatment, further, first by protamine sulfate and antiseptic 2 in the present invention, 4,4 '-three chloro-2 '-dihydroxy diphenyl ether, the composite use of hexamethylene, and at surfactant N, N-bis-(hydroxyethyl) coconut oleoyl amine collaborative under, antibacterial effect notable synergistic.
Relative to prior art, the marked improvement major embodiment of technical solution of the present invention be the present invention by fibers mixture different for acid fiber by polylactic and Coolmax fiber two kinds of performances together, fabric has good gas permeability and excellent moisture absorption control ability.Further, by anti-bacterial finish, fabric bacteriostasis rate is high, thus can available protecting health.
Detailed description of the invention
Embodiment 1
Select commercially available acid fiber by polylactic and Coolmax fiber, mass ratio is 30:70.
By the acid fiber by polylactic shredding preliminary treatment taken by said ratio, carding machine is carded to the carded sliver; By the Coolmax fiber opening preliminary treatment taken by said ratio, carding machine is carded to the carded sliver; Then the acid fiber by polylactic carded sliver and the Coolmax fiber carded sliver are closed on drawing frame, make ripe bar; Speed frames carry out drawing-off and twisting, and finally further draw twisting on fine spining machine, makes Coolmax fiber and acid fiber by polylactic blended yarn.Large circle machine knitting device making method is adopted to weave Coolmax fiber and acid fiber by polylactic blended yarn again, the fabric of final obtained acid fiber by polylactic and Coolmax fiber blend.
Obviously, above-mentioned blended yarn and the preparation technology of fabric are the universal method of the industry, for well known to those of ordinary skill in the art.
Embodiment 2
Get the fabric of acid fiber by polylactic obtained by section Example 1 and Coolmax fiber blend, carry out anti-bacterial finish further, concrete steps are:
