Problems solved by technology

Before the present invention was made, in the Chinese invention patent of CN86107140 "Resin Treatment Method for Textiles Containing Cellulose Fibers", a resin bath composed of water-soluble urethane prepolymers was disclosed for finishing cellulose-containing fibers. A method for fiber textiles, although this method can improve the dry wrinkle resistance, wet wrinkle resistance and washable wearability of textiles containing cellulose fibers, but due to the use of resin anti-wrinkle finishing agents in the processing, it is in the finishing process Formaldehyde will be released in the process of taking and taking, which is extremely harmful to human health.

Embodiment 1

[0017] The twisted 50.5 Tex cotton yarn is scoured with caustic soda to remove impurities, and then bleached with hydrogen peroxide.

[0018] Prepare 0.06mol / L sodium periodate solution, adjust the pH value to 6.0, add cotton yarn and keep the reaction temperature at 55°C under the condition of bath ratio 1:200, take it out after 10 hours of treatment, and add it in 0.1mol / L glycerol Soak in the solution for 30 minutes.

[0019] Soak in water at room temperature for 24 hours, wash with warm water for several times, dehydrate, and dry at 60°C to obtain elastic cotton fibers with a basic specification of 60-65 tex, with an elongation of 10-12%. The elastic deformation is 55-58%; while the same kind of cotton fiber not treated by this method generally has an elastic deformation of 39-40%.

Embodiment 2

[0021] The twisted 50.5 Tex cotton yarn is scoured with caustic soda to remove impurities, and then bleached with hydrogen peroxide.

[0022] Prepare a 0.3mol / L sodium periodate solution, adjust the pH value to 6.0, add cotton yarn and keep the reaction temperature at 60°C under the condition of a bath ratio of 1:200, take it out after 2 hours of treatment, and put it in 0.1mol / L glycerol Soak in the solution for 30 minutes, or soak in water at room temperature for about 24 hours, wash with warm water for several times, dehydrate, and dry at 60°C to obtain elastic cotton fibers with a basic specification of 80-85 tex. The elongation is about 18%, and the elastic deformation is 50-60%; while the elastic deformation of ordinary cotton fibers without this method is about 40%.

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 í‹chemical fiberizeíŒ 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 [0001] The invention relates to a preparation method of anti-wrinkle cotton fiber, in particular to a method of chemically modifying the cotton fiber for bouncing treatment and endowing it with elasticity. Background technique [0002] Cotton fiber is a linear semi-rigid natural polymer compound formed by D-glucopyranose anhydride linked by β-1,4-glycosidic bonds. There are 3 active hydroxyl groups on each glucosyl ring in its macromolecular chain ( two secondary hydroxyl groups and one primary hydroxyl group), it is renewable and resource-rich. As a natural cellulose fiber, cotton fiber has the characteristics of good hygroscopicity, air permeability, warmth retention, antistatic property and soft hand feeling, and plays an important role in the field of textile fiber materials. However, poor anti-wrinkle and non-ironing properties and easy shrinkage after washing have always been the main shortcomings of cotton fiber. [0003] Sinc...
