Description
Technical field
The present invention relates to polyamide fibre technical field, particularly relate to a kind of processing technology of easy moisture absorption nylon fibre.
Background technology
Polyamide fibre, formal name used at school polyamide fiber, is commonly called as nylon (Nylon), and English name Polyamide (being called for short PA), polyamide fibre is the trade name of polyamide fiber, density 1.15g/cm
3, be the thermoplastic resin general name containing recurring amide radical group (-NHCO-) on molecular backbone.Principal item has polyamide fibre 6 and polyamide fibre 66.POLYAMIDE YARNS is the fiber made with polyamide, point chinlon filament and the short silk of polyamide fibre, and chinlon filament can be made into elastic filament, short silk can with cotton and acrylic fibers blending, to improve its intensity and elasticity.
Polyamide fibre occupies critical role in apparel industry all the time, but when it is used for making dress material, the sheet of directly contact skin, due to its at standard conditions hygroscopicity only have 3.5%, people can be made to have scratchy, feeling of oppression and heat.Along with the raising of the level of consumption, people not only require attractive in appearance to nylon fabric, also require comfortableness.And the comfortableness of nylon fabric and the hydrophily of fabric closely related, thus improving hydrophily is improve the important research direction of comfort of fabric.The current method improving nylon fibre moisture pick-up properties has: a and a small amount of hydrophilic component are as blended in PVP etc.; B, hydrophilic component and caprolactam copolymerization; C, first copolymerization formed hydrophilic polyamide, then with slices of caprone co-blended spinning; D, on polyamide fibre molecular backbone the group such as carboxyl grafting, amido, cyano group, hydroxyl; E, by changing fibre section shape, making fiber heteromorphosis, fine, surface roughening or make processbearing astrocyte micropore to increase surface area, to improve hygroscopicity; F, by hydrophilic agent, aft-loaded airfoil process is carried out to polyamide fibre or its fabric.In above method, copolymerization and Graft Method complex process, cost be high, be difficult to batch production.Physical needs special profile spinneret.The fiber hygroscopicity that post treatment method obtains is difficult to lastingly, blending method due to technique simple, modified effect is obvious and be subject to extensive use.But nylon fibre moisture pick-up properties of the prior art has much room for improvement.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of processing technology of easy moisture absorption nylon fibre, nylon fibre hygroscopicity prepared by this technique is excellent.
For reaching this object, the present invention by the following technical solutions:
A processing technology for easy moisture absorption nylon fibre, comprises the steps:
(1) 50 ~ 70 parts of slices of caprone, the PVP of 2 ~ 10 parts, the alkylphenol polyoxyethylene of 5 ~ 10 parts, 1 ~ 5 part of dispersant, 2 ~ 10 parts of antioxidant by weight, are taken;
(2) by after slices of caprone drying, blended with PVP, alkylphenol polyoxyethylene, dispersant, antioxidant, melt spinning is prepared into nylon fibre, is soaked in by nylon fibre in hydrophilic solvent after drying, prepares easy moisture absorption nylon fibre.
Polyvinylpyrrolidone (PolyvinylPyrrolidone) is called for short PVP, is a kind of non-ionic water-soluble macromolecular compound, is most characteristic in N vinylamide polymer and is studied the most deep kind of fine chemistry widely.PVP has the general aspects of water-soluble high-molecular compound; as colloid protective effect, film forming, cohesiveness, hygroscopicity, solubilising or cohesion, coordination ability etc. with some compound, the present invention adopts polyvinylpyrrolidone to be apply its good hygroscopicity.PVP is divided into level Four by its mean molecule quantity size, often traditionally represents with K value, and different K values represents corresponding PVP average molecular weight range respectively.K value is actually the characteristic value relevant with the relative viscosity of the PVP aqueous solution, and viscosity is the physical quantity relevant with molecular weight of high polymer, therefore can characterize the mean molecule quantity of PVP by K value.Usual K value is larger, and its viscosity is larger, and cementability is stronger.Preferably, the K value of PVP of the present invention is 30.
Alkylphenol polyoxyethylene (polyoxyethylenealkylphenolether), also known as OP type surfactant, be called for short phenolic ether, code name APE, belongs to non-ionic surface active agent.Alkylphenol polyoxyethylene is formed by alkyl phenol and oxirane adduction, and the chemical stability of alkylphenol polyoxyethylene is high, even if at high temperature also not easily destroyed by strong acid and strong base, but biological degradability is poor.Because APE has good wettability, permeability, emulsibility and detergency, in degreasing power and emulsification, have the irreplaceable performance of fatty alcohol-polyoxyethylene ether, be widely used in all trades and professions, its occupation rate of market just grows steadily.The present invention selects alkylphenol polyoxyethylene, applies its good wettability and permeability, adds in nylon fibre, and its moisture pick-up properties is improved.
Preferably, in step (1), described PVP is PVP (K30).The spinning-grade slices of caprone of described slices of caprone to be viscosity be 3 ~ 4dl/g.Described dispersant is polycaprolactone.Described antioxidant is one in antioxidant 1098, antioxidant 1076, antioxidant SEED or at least two kinds.It is pointed out that described dispersant, antioxidant also can be other conventional reagent of this area, do not repeat them here.
Preferably, in step (2), the temperature of described drying is 160 ~ 170 DEG C.The temperature of described melt spinning is 260 ~ 270 DEG C, and the speed of described melt spinning is 1000 ~ 1500m/min.Described hydrophilic solvent is one in 2-amide groups sodium propionate, 3-amide groups sodium propionate, caprylamide sodium acetate and caprylamide propionate or at least two kinds.
Compared with prior art, beneficial effect of the present invention is: the processing technology of a kind of easy moisture absorption nylon fibre of the present invention, comprise the following steps: (1) by weight, takes 50 ~ 70 parts of slices of caprone, the PVP of 2 ~ 10 parts, the alkylphenol polyoxyethylene of 5 ~ 10 parts, 1 ~ 5 part of dispersant, 2 ~ 10 parts of antioxidant, (2) by after slices of caprone drying, after blended with PVP, alkylphenol polyoxyethylene, dispersant, antioxidant, melt spinning is prepared into nylon fibre, is soaked in by nylon fibre in hydrophilic solvent and prepares easy moisture absorption nylon fibre after drying, adding of polyvinylpyrrolidone, the moisture pick-up properties of nylon fibre can be improved, simultaneously, alkylphenol polyoxyethylene makes nylon fibre have stronger permeability and diffusivity as non-ionic surface active agent, use with polyvinylpyrrolidone simultaneously, the moisture pick-up properties of further enhancing nylon fibre, when with slices of caprone co-blended spinning, polyvinylpyrrolidone and alkylphenol polyoxyethylene are uniformly distributed in slices of caprone under the effect of dispersant, and there is stronger intermolecular interaction between the strand of slices of caprone, the nylon fibre hydrophilic solvent prepared is soaked, improve again the hygroscopicity of nylon fibre further, preparation technology of the present invention is simple, and the nylon fibre hygroscopicity prepared is strong.
