The role of printing paste in printing processing In textile printing, the performance of the printing paste directly affects the quality of the printed product, and its main functions in the printing process are: (1) As printing thickener; (2) As dispersion medium and diluent in printing paste; (3) Read More
Pretreatment steps of nylon and its elastic fabrics: smoothing → desizing → scouring 1. Desizing of nylon woven fabricDesizing agent 8 g/LChelating dispersant 1 g/LLiquid caustic soda (30%) 30g/L Continuous open width desizing, speed 40m/min, using the first two working fluids, overflow washing one Read More
Desizing purpose During the weaving process, the warp yarns are subject to greater tension and friction, and are prone to breakage. In order to reduce warp breakage and improve weaving efficiency and grey fabric quality, warp yarns need to be sizing before weaving. The fibers in the yarns are cohesi Read More
There are many commonly used desizing methods, including enzyme, alkali, acid and oxidant desizing, etc. The appropriate desizing method can be selected according to the variety of the original fabric, the composition of the slurry, the desizing requirements and the factory equipment. After desizing Read More
Mercerized cotton fabricThe mercerized cotton fabric is to first pass the yarn through singeing to remove the miscellaneous hair on the surface of the thread, and then make the yarn have tension in the high temperature alkali. Well, the brighter and smoother the yarn. It not only maintains the chara Read More
Nowadays, the price transmission of the industrial chain has been hindered, and the phenomenon that grey fabrics are hard to rise has made the downstream resistance gradually stronger, so the loss of downstream weaving and texturing has increased significantly. Therefore, starting from the second ha Read More
Dye selection (the most important factor)①High light fastness of yellow chromatography: reactive dyes take pyrazolinium and naphthalene trisulfonic acid as the parent structure;②High light fastness of blue spectrum: reactive dyes take anthraquinone, phthalocyanine and methyl ester as the parent stru Read More
Spandex dew whiteAs we all know, polyurethane elastic fiber (spandex) can be dyed with disperse dyes and acid dyes, but the fastness of these two dyes is poor. And most of the experiments have proved that nylon with reactive dyes (dyed nylon elastic cloth) and disperse cationic dyes (dyed CDP elasti Read More
Woven fabrics, knitted fabrics and other types of fabrics must undergo dyeing and finishing processes, such as scouring and bleaching, dyeing or printing, finishing and other processes after they are placed on the loom, in order to complete the above-mentioned finishing content, which means that the Read More
