Abstract
The invention relates to anti-crease cotton fiber manufacturing method, especially for chemical modification processing than means processing elastic starting and endowing with elasticity. It includes the following steps: boiling-off twisted cotton yarn and bleaching; processing selective oxidation reaction by putting the cotton yarn into periodate with 0.05-0.6mol/L concentration at 40-60 centigrade degree for 1-16h; removing the oxidant; washing; dehydrating; drying; gaining anti crease cotton fiber. The method not uses any cross linking agent and chemical additive. This can prevent natural cotton fiber ''chemical fiberize'' in tradition modification method. The resilience cotton fiber material can be applied to the processing of woven, braided and knitted fabric. The cotton goods have good absorbent quality, permeability, stability and elasticity, and can greatly expand cotton fiber application area.
Description
Technical field
The present invention relates to a kind of preparation method of crease-resistant cotton fiber, particularly a kind of with the chemical modification processing, cotton fiber is played bullet handle and give its flexible method.
Background technology
Cotton fiber is with β-1 by D-glucopyranose acid anhydride, the linear semi-rigid natural polymer that the 4-glycosidic bond links, 3 active hydroxyls (two secondary hydroxyls and a primary hydroxyl) are arranged, its renewable, aboundresources on each glucose basic ring in its macromolecular chain.As a kind of native cellulose fibre, cotton fiber has good hygroscopicity, gas permeability, warmth retention property, antistatic behaviour and characteristics such as soft, is playing the part of important role in the textile fiber material field.But crease-resistant easy-care properties is poor, washing is easily shunk, and is the major defect that cotton fiber exists always.
The U.S. has solved the crease-resistant finishing of cotton fabric technical problem first from 1920's, and the crease-resistant finishing of cotton fabric technology reaches its maturity.Conventional at present crease-shedding finishing agent has N-hydroxymethyl resin class crease-shedding finishing agent, has occurred modification 2D resin and formaldehydeless polybasic carboxylic acid class crease-shedding finishing agent subsequently again.Before the present invention makes, publication number is in the Chinese invention patent " the resin treatment method of the textiles of cellulose fiber " of CN86107140, the method of the resin bath arrangement cellulose fiber textile of the water-soluble carbamate prepolymer composition of a kind of usefulness is disclosed, though this method can make the dried wrinkle resistance of textiles of cellulose fiber and wet wrinkle resistance and wash and wear performance improve, but because work in-process has used the resin anti creasefinish agent, it can discharge formaldehyde in the arrangement process with taking in the process, and is very big to human health damage.Publication number is during the Chinese invention patent of CN1039456 " carries out formaldehyde-free durable with polybasic carboxylic acid to COTTON FABRIC and presses technology and the employed catalyst that scalds arrangement ", disclose a kind of polybasic carboxylic acid COTTON FABRIC has been carried out the technology that formaldehyde-free durable is pressed boiling hot arrangement, promptly when the heating elevated temperature, make polybasic carboxylic acid with the cellulose in the textiles under catalyst action, esterification and cross-linking reaction take place rapidly, and COTTON FABRIC has improved wrinkle resistance and easy-care properties after treatment.Because use resin or polybasic carboxylic acid to make crease-shedding finishing agent, one deck chemical substance has inevitably been adhered on the cotton fiber surface, causes " chemical fibreization " on natural cotton fiber surface, has destroyed the original looks of this green natural cellulose fibre of cotton fiber.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of and can realize and keep the flexible preparation method of natural cotton fiber effectively.
The present invention adopts following technical scheme to realize purpose of the present invention: a kind of preparation method of crease-resistant cotton fiber is provided, and it adopts following concrete steps:
A. to carrying out kiering, bleaching processing through twisting with the fingers cotton also;
B. it is that the periodate solution of 0.05～0.6mol/L carries out selective oxidation reaction and handles that the cotton after will handling places concentration, and the reaction solution temperature is 40～60 ℃, and the processing time is 1～16 hour;
C. remove the oxidant on the cotton fiber, through washing, dehydration, oven dry, obtain crease-resistant cotton fiber again.
Described periodate is sodium metaperiodate or potassium metaperiodate.The method of oxidant is on the described removal cotton fiber: cotton fiber was soaked 30～60 minutes in concentration is the glycerol solution of 0.1～0.5mol/L.
The mechanism of technical solution of the present invention is: cotton fiber is selective oxidation under certain condition, makes C in the gossypin macromolecular chain glucopyranose anhydro ring joint
2And C
3Secondary hydroxyl selective oxidation on the position becomes aldehyde radical, to C
6Primary hydroxyl on the position does not have effect substantially, under the technology of the present invention condition, and C in the cotton fiber macromolecular chain
2And C
3Secondary hydroxyl on the position is by the high selectivity oxidation, thereby, the big intermolecular hydrogen bond action of natural cotton fiber is weakened, the molecular thermalmotion aggravation, strand generation creep causes the cotton fiber crimp shrinkage, forms the accumulated inside energy, realize and kept enduringly the elasticity of natural cotton fiber effectively, improved the crease-resistant ability of natural cotton fiber effectively.
Compare with the crease-resistant technological treatment of existing cotton fiber, the present invention has following tangible advantage:
1. the present invention adopts the elastic cotton fiber of periodate process for selective oxidation preparation, does not use any crosslinking agent or other chemical addition agent, has avoided the problem of natural cotton fiber " chemical fibreization " in traditional method of modifying.Simultaneously, the oxidation cotton fiber is a kind of as cellulose derivative, still has excellent biological compatibility, biodegradability, environmental friendliness and characteristics such as nontoxic, and it has kept the good characteristic of natural cotton fiber.
2. the method for the present invention's employing makes after the enough shrinkage crimpings of oxidation cotton fiber generation and has elastic force, thereby has improved the wrinkle resistance of cotton fiber effectively from the textile fiber material field.This elastic cotton fibrous raw material is applicable to the processing of woven fabric, braided fabric and knitted fabric, and the cotton goods of making have thick and heavy sense, good hygroscopicity, gas permeability, morphological stability and elasticity, has expanded the Application Areas of cotton fiber greatly.
3. the preparation method of crease-resistant cotton fiber provided by the present invention, low production cost, simple to operate, production efficiency is high.
The specific embodiment
The invention will be further elaborated below in conjunction with embodiment.
Embodiment one:
To remove impurity with caustic scouring through twisting with the fingers 50.5 Tekes cottons also, use hydrogen peroxide bleaching again.
The sodium periodate solution of preparation 0.06mol/L, regulating the pH value is 6.0, adds cotton and keep 55 ℃ of reaction temperatures under the condition of bath raio 1:200, handles after 10 hours and takes out, and soaks 30 minutes in 0.1mol/L glycerol solution.
Be soaked in water under the room temperature 24 hours, warm water washing back dehydration is for several times dried in 60 ℃ environment, and can obtain basic specification is the elastic cotton fiber of 60～65 Tekes, and its percentage elongation is 10～12%, and strain is 55～58%; And the cotton fiber of handling without this method of the same race, strain is generally 39～40%.
