The main processes of Chinese linen cotton Chinese linen cotton fabric manufacturer's manufacturer are: raw cloth preparation, singeing, desizing, scouring, bleaching and mercerizing.
1) Original cloth preparation: The original cloth preparation includes original cloth inspection, cloth turning (batch, binning, printing) and seam head. The purpose of the original cloth inspection is to check the quality of the grey cloth and find out that the problem can be solved in time. The inspection includes physical indicators and appearance defects. The former includes the length, amplitude, weight, warp and weft yarn density and density, strength, etc. of the original fabric, such as spinning, weaving, various types of stains and damage. Usually check the total amount of about 10%. After the original cloth inspection, the original cloth must be batched, binned, and printed on the cloth head, indicating the variety, processing technology, batch number, box number, release date and the code of the person to be transferred for management. In order to ensure continuous batch processing, the original cloth must be sewn.
2) Singeing: The purpose of singeing is to burn the fluff on the cloth surface to make the cloth surface smooth and beautiful, and to prevent uneven dyeing and printing plague due to the presence of fluff during dyeing and printing. China's linen cotton fabric manufacturer singeing is to quickly pass the Chinese linen cotton fabric manufacturer through a high-temperature flame or rub the red hot metal surface. At this time, the fluff existing on the cloth surface heats up quickly and burns. The body is relatively tight and the temperature rises slowly. When it is not raised to the point of fire, it has left the flame or the red hot metal surface, so as to achieve the purpose of burning the fluff and not operating the Chinese linen cotton fabric manufacturer.
3) Desizing: In order to smooth the weaving, the textile factory often sizing the warp yarn to improve the strength and wear resistance. The slurry on the grey cloth affects the water absorption performance of Chinese linen cotton fabric manufacturers, and also affects the quality of dyeing and finishing products, and will increase the consumption of dyed chemicals. Therefore, the slurry should be removed before scouring. This process is called desizing. . The pulp of the cotton Chinese linen cotton fabric manufacturer can be removed from the Chinese linen cotton fabric manufacturer by means of alkali desizing, enzyme desizing, acid desizing and oxidizing desizing. Alkali desizing causes the slurry to puff, and the adhesion to the fiber decreases, and is removed from the Chinese linen cotton fabric manufacturer by water washing. Enzymes, acids, and oxidants degrade starch, increase solubility in water, and be removed by washing. Because acid and oxidant have great damage to cotton fiber, they are rarely used alone, and are often used in combination with enzyme desizing and alkali desizing.
