Technical Field

[0001] The invention belongs to the technical field of fabrics, and particularly relates to a processing method of high-elastic fabrics. Background Art

[0002] With the development of society, the field of fabric technology has made great progress. Whether it is pure cotton fabric or chemical fiber fabric, its application field is very wide, and the performance requirements for fabrics are also different. Some require high-elastic fabrics, while others have great restrictions on the elasticity of fabrics.

[0003] The Chinese invention patent application document with application number 202011126923.3 requires a large amount of water in the dyeing process, and the pH value of the dye solution needs to be adjusted multiple times, which makes the production process too complicated and not conducive to mass production in the company's workshop. Therefore, it is necessary to provide a high-elastic fabric and a processing method that is easy to operate, which is suitable for mass production of enterprises. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for processing high-elastic fabrics.

[0005] The present invention adopts the following technical solution:

[0006] The processing method of high elastic fabric is to weave 70D~150D polyester and 40D~70D spandex to obtain grey fabric, the amount of polyester is 70%~80%, the amount of spandex is 20%~30%, and the surface density is 170g / cm 2 -200g / cm 2 ;

[0007] At the same time, the obtained grey cloth is processed to obtain a high-elastic fabric, and the processing method specifically includes the following steps: primary cleaning, pre-setting, dyeing, secondary cleaning and post-finishing, wherein:

[0008] The one-time cleaning process adopts the following steps: adding clean water into the cleaning tank, and then adding the following components according to the water volume: 1-1.5 g / L refined degreasing agent TY1-20, 0.7-0.8 g / L surfactant NP-10, 8-10 g / L nano zeolite powder;

[0009] The dyeing auxiliary agent includes the following components in terms of water volume: 0.4-0.6 g / L of adhesive XSBRL, 0.2-0.4 g / L of 2,3-butanediol, 8-10 g / L of nano zeolite powder, and 6-10 g / L of cardanol ether BGF-9.

[0010] Furthermore, the secondary cleaning process adopts the following steps: adding clean water into the cleaning tank, and then adding the following components according to the water volume: 3~4g / L sodium hypochlorite, 4~6g / L liquid alkali, 1~2g / L color fixing agent SP660, 2~5 g / L dodecanol ester.

[0011] Furthermore, the predetermined forming temperature is 182-190° C., the time is 18-24 seconds, and the positive overfeed is 9-12%.

[0012] Furthermore, disperse dyes are added during the dyeing process, and the dyeing temperature is: first, the temperature is increased to 100-105°C at a heating rate of 3-4°C / min, and the temperature is kept constant for 10-20 minutes; then, the temperature is increased to 130-135°C at a heating rate of 2-2.5°C / min, and the temperature is kept constant for 20-30 minutes; finally, the temperature is cooled to room temperature at a cooling rate of 7-10°C / min.

[0013] Furthermore, the temperature of the first cleaning is 85-90°C, and the time is 30-40 minutes; the temperature of the second cleaning is 80-90°C, and the time is 20-30 minutes.

[0014] Furthermore, the post-finishing process is specifically to immerse the fabric after the second cleaning in 25-30 g / L of antibacterial and mildew-proof agent KJFM for 5-10 minutes.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, in order to improve the dyeing effect, during a cleaning process, refined degreasing agent TY1-20 and surfactant NP-10 were added to improve the cleaning effect. At the same time, nano zeolite powder was added to absorb impurities in the grey cloth to further improve the cleaning effect.

[0017] Second, during the dyeing process, cardanol ether BGF-9 is used as an emulsifier to mix the adhesive XSBRL and coupling agent 2,3-butanediol and nano zeolite powder to improve the adsorption of dyes on fabrics and improve color fastness.

[0018] Not only that, in order to enhance the effect of dyeing auxiliaries, different temperature ranges are designed during dyeing to further improve the color fastness of the fabric.

[0019] Third, through secondary cleaning, the fixing agent SP660 is mixed with the film-forming dodecanol ester to form a protective film on the fabric fibers and improve color fastness. DETAILED DESCRIPTION
