Home Textile Fabrics Suppliers Introduces How To Use Fabric Dyeing
Home Textile Fabrics Suppliers introduces the process flow of fabric dyeing:
① Preparation of original cloth: preparation of original cloth includes original cloth inspection, cloth turning (batch, box, printing) and seam head. The purpose is to check the quality of the grey fabric. Including the length, width, weight, warp and weft yarn density and density, strength, etc. of the original fabric, as well as spinning defects, weaving defects, various stains and breakages.
② Singeing: Fabric singeing is to quickly pass the fabric through a high-temperature flame or rub it across a red hot metal surface. At this time, the fluff existing on the fabric surface will quickly heat up and burn, and the cloth body is tighter and the temperature rises more. Slow, before reaching the fire point, it has left the flame or red hot metal surface, so as to achieve the purpose of burning off the fluff without operating the fabric. The purpose is to burn off the fluff on the cloth surface to make the cloth surface smooth and beautiful, and to prevent uneven dyeing and printing defects due to the existence of fluff during dyeing and printing.
③ Desizing: For smooth weaving, textile mills often sizing warp yarns to improve strength and wear resistance. The slurry on the grey fabric not only affects the water absorption performance of the fabric, but also affects the quality of dyeing and finishing products, and will increase the consumption of dyeing chemicals. Therefore, the slurry should be removed before scouring. This process is called desizing. The size of the cotton fabric can be removed from the fabric by alkali desizing, enzyme desizing, acid desizing and oxidizing agent desizing.
④ Scouring: When cotton fiber grows, it is accompanied by natural impurities. After desizing, there is still a small amount of slurry and natural impurities still remaining on the fabric. Therefore, the fabric needs to be scoured for a long time in high-temperature concentrated lye to remove residual impurities. Scouring is the use of caustic soda and other scouring aids to chemically react with natural impurities. After washing with water, the impurities are removed from the fabric.
⑤ Bleaching: After the cotton fabric is scoured, there are natural pigments on the fiber, and its appearance is not white enough. If it is used for dyeing or printing, it will affect the vividness of the color. The purpose of bleaching is to remove pigments and give the fabric the necessary and stable whiteness, while the fiber itself is not significantly damaged. Commonly used bleaching methods for cotton fabrics are sodium nitrite method, hydrogen peroxide method and sodium chlorite method.
⑥ Dyeing: refers to the physical or chemical combination of dyes and fibers, or the use of chemical methods to generate pigments on the fibers, so that the entire textile has a certain color. Dyeing is carried out under certain conditions of temperature, time, pH value and required dyeing auxiliaries.
⑦ Mercerizing: refers to the processing process of cotton fabrics under the condition of tension in the warp and weft directions at room temperature or low temperature, treated with concentrated caustic soda solution to improve the properties of the fabric. After mercerizing, be sure to use flushing to remove alkali or steaming to remove alkali, or to remove alkali by washing on the floor, etc., until the fabric is neutral.
⑧ Finishing: A textile technology project that gives clothing fabrics wearability and beautiful appearance.
