Abstract
The invention discloses a method for improving water and moisture absorbing performance of acrylic fiber by using gamma-polyglutamic acid hydrogel. The method is used for settling fabric by using gamma-polyglutamic acid as a finishing agent and ethylene glycol diglycidyl ether as a cross-linking agent. The method includes the steps of dissolving the gamma-polyglutamic acid in distilled water or tap water, preparing a 4%-20% solution, adding ethylene glycol diglycidyl ether according to 20%-60% of the mass of the gamma-polyglutamic acid, and stirring evenly so as to mix evenly. Acrylic fiber is soaked in a fishing liquid for 5-10 minutes, soaked and rolled twice by using a padder, rolling surplus rate of the fabric is 65-110%, the soaked and rolled fabric is wrapped by a preservative film and reacts for 5h-25h in an oven at the temperature of 40-80 DEG C, then the preservative film is removed, and the fabric is dried. Or the soaked and rolled fabric is baked for 5-10 minutes in a baking machine at the temperature of 110-140 DEG C. Standard moisture regain and moisture absorbing amount of the settled acrylic fiber are greatly increased, and wearing comfortableness is remarkably improved.
Description
Affiliated technical field:
The present invention relates to the method for acrylic fabric suction hygroscopicity arrangement, is that a kind of bioabsorbable polymer material gamma-polyglutamic acid-aquogel arrangement acrylic fabric that utilizes improves the hygroscopic method of suction specifically.
Technical background:
Acrylic fibers are the copolymers with acrylonitrile more than 85% and the second and the 3rd monomer, the synthetic fiber that make through wet spinning or dry spinning.The fiber that the copolymer spinning of acrylonitrile content between 35%～85% makes is called modified acrylic fibre.
The performance utmost point of polyacrylonitrile fibre is better like wool elasticity, extends 20% o'clock rebound degree and still can keep 65%, and fluffy curling is and soft, and warmth retention property is higher by 15% than wool, and intensity 22.1～48.5cN/dtex is higher 1～2.5 times than wool.The sun-proof function admirable, open-air exposure 1 year, intensity only descends 20%, and 190～230 ℃ of fiber softening temperature can be acidproof, antioxidant and common organic solvents, but alkali resistance is relatively poor.Have soft, bulk, be prone to dye, bright in colour, fast light, antibiotic, be not afraid of advantage such as damage by worms, the title of artificial wool is arranged.Can purely spin or with natural fibre blended, its textiles is widely used in fields such as clothes, decoration, industry according to the requirement of different purposes.
Although the function admirable of acrylic fiber, still there is critical defect in it on wearability, and it is low serious with electrostatic phenomenon mainly to show as hygroscopicity.These shortcomings not only badly influence the snugness of fit of acrylic fabric, also have influence on the production safety of enterprise, the inflammable explosive article initiation fire thereby the static that acrylic fabric produces possibly ignite.Therefore it is very necessary acrylic fabric being carried out hydrophilic finiss raising suction hygroscopicity.
Summary of the invention:
The present invention provides gamma-polyglutamic acid-aquogel arrangement to improve the acrylic fabric hygroscopic method that absorbs water;
Technical scheme of the present invention is following: it is 4%～20% the aqueous solution that gamma-polyglutamic acid-is mixed with mass percent, adds ethylene glycol diglycidylether in the gamma-polyglutamic acid-solution and obtains dressing liquid, fully stirs.Acrylic fabric soaked in dressing liquid 5～10 minutes; Temperature is 18-28 ℃, soaks two with padding machine two and rolls, and the pick-up that makes fabric is 65%～110%; To pad good fabric and wrap up with preservative film and in 40 ℃～80 ℃ baking ovens, react 5h～25h, remove the preservative film oven dry then; Maybe will pad good fabric baked 5～10 minutes in 110 ℃～140 bakers.
Said ethylene glycol diglycidylether consumption is 20%～60% of a gamma-polyglutamic acid-quality.
Gamma-polyglutamic acid-concentration of aqueous solution preferred 6%～20%; Said gamma-polyglutamic acid-concentration of aqueous solution preferred 8%.Best pick-up is 65%; Optimal reaction temperature is 50 ℃.
Beneficial effect:
The present invention compares advantage with existing invention: use gamma-polyglutamic acid-as finishing agent; Ethylene glycol diglycidylether is made crosslinking agent; Gamma-polyglutamic acid-is by the synthetic amino acid polymer of microorganism; Containing a large amount of hydrophily carboxylic groups on the strand, have moisture retention and biodegradable, is a kind of Bc new type natural macromolecular material to human body and environment nonhazardous; Through the appropriately crosslinked water absorbent gel that forms of crosslinking agent, put the suction moisture pick-up properties that can improve fabric on the fabric in order.
