Description
Technical Field
The invention relates to the technical field of garment processing, in particular to a method for crease-resist finishing of clothing by using dihydroxyethylene urea resin.
Background
Cotton fibers have very high moisture absorption and swelling properties. Cotton textiles, such as clothing, ladies, trousers or bed textiles, have a very high comfort; however, cotton textiles have the disadvantage of being prone to wrinkling and of shrinking severely under wet processing conditions due to swelling, in comparison with synthetic fiber textiles. While people seek to wear comfortable, the size and shape of the textile are also required to be stable and easy to care, so crease resistance, low temperature ironing, non-ironing and the like become very important additional properties of the clothes.
The non-ironing property is that the fabric has wrinkle resistance in the wearing process, and can still keep good flat state or pleat and stable form without ironing after washing, namely the finished fabric has excellent wrinkle resistance in a dry and wet state. At present, the domestic non-ironing technology mainly comprises liquid ammonia finishing, resin treatment and the like.
During liquid ammonia finishing, ammonia permeates into the fiber instantaneously, so that the fiber crystal structure of the cotton fiber is changed, the torsional stress in the fiber is reduced or disappears, the anti-wrinkle effect is achieved, the pulling strength and the tearing strength of the fabric are improved, the dimensional stability of the fabric is improved, the contractility of the fabric during washing is greatly improved, meanwhile, the smoothness among the fibers is enhanced, the surface is smooth, and the excellent softness of the cotton fiber is achieved. The hand feeling can be kept good even after repeated washing. However, due to the danger of the liquid ammonia, the technology is not adopted by general enterprises.
The resin treatment is to use resin and other additives to change the physical and chemical properties of the fiber and fabric and improve the shrink-proof and crease-resistant properties of the fabric. The resin and the hydroxyl groups in two cellulose molecules form covalent crosslinking to mutually link adjacent molecular chains, so that the deformation which cannot be immediately recovered due to the hydrogen bond disintegration is reduced, and the recovery capability of the fiber from the deformation is improved. Therefore, to improve the wrinkle recovery of pure cotton fabrics, it is most effective to introduce a suitable amount of stable cross-linking in the amorphous regions of the fibers. After the pure cotton fabric is treated by the special finishing agent, the finishing agent generates covalent cross bonds among molecular chains in an amorphous area in the form of single molecules or polycondensates, just as if the single molecules of the finishing agent extend out of two powerful 'big hands' to tightly hold the molecular chains in the amorphous area, the effects of restraining and fixing are generated among the molecular chains of fibers, so that the molecular chains of the fibers cannot generate relative displacement, and the deformation which cannot be immediately recovered is reduced, thereby improving the deformation recovery capability of the fibers and achieving the purposes of resisting wrinkles and avoiding ironing.
In order to obtain a better non-ironing effect of the final clothes, the non-ironing finishing liquid is required to fully react with fibers in the fabric. The currently commonly used after-finishing process comprises four steps: (1) washing the clothes with water; (2) fully soaking the fabric in a non-ironing finishing agent for washing; (3) statically hanging the washed clothes for a period of time; (4) and washing with water again to remove redundant reagents, drying and packaging. The clothes after-finishing process has the advantages of long production period, occupation of a large number of production plants, low utilization rate of the non-ironing finishing agent and overhigh production cost.

(6) and (3) squeezing: the clothes and the auxiliary medicine soaking tool which are fully soaked with the non-ironing finishing liquid are lifted out of the medicine soaking pool and suspended above the medicine soaking pool, a control system of the auxiliary medicine soaking tool is started again, and the stacked clothes in the auxiliary medicine soaking tool are repeatedly extruded for 3-5 times, so that the liquid carrying rate of the clothes is reduced to 30% -45%;
(7) drying in a constant humidity mode: conveying the stacked clothes in the auxiliary medicine soaking tool into an oven through a conveying device, heating at 45-55 ℃, and controlling the liquid carrying rate of the clothes to be reduced to 10-20%;
(8) shaping and pressing: flatly paving the clothes processed in the step (7) into a pressing machine piece by piece, sizing and pressing by adopting the temperature of 160-170 ℃ and the pressure of 3kg/cm, wherein the pressing time is 8-10 seconds, so that the non-ironing finishing liquid and the fabric fibers are subjected to partial cross-linking reaction;
(9) baking and shaping: hanging the clothes processed in the step (8), and sending the clothes into a baking and forming machine for baking at the temperature of 140-150 ℃ for 5-6 minutes to enable the non-ironing finishing agent and fabric fibers to realize cross-linking reaction and form;
(10) slow cooling and rewetting: and (4) putting the clothes processed in the step (9) into a constant temperature and humidity chamber for slow cooling and moisture regaining, wherein the conditions of the constant temperature and humidity chamber are as follows: the temperature is 22 ℃, the relative humidity is 75 percent, and the treatment time is 4 hours;
(11) cleaning: putting the clothes treated in the step (10) into clear water with the water temperature of 30 ℃ for repeatedly cleaning for more than 2 times, removing solvents such as unreacted non-ironing finishing liquid and the like, and dehydrating and drying;
(12) and conveying the finished clothes after treatment to a next process through a conveying device.
