What is wet processing in textile?
Those fabric finishing processes which carried out using wet media, especially Desizing, Scouring, Bleaching ,Dying, Printing and Finishing etc. are called textile wet processing.
What are the effects to the textile after finished treatment if the desizing is not good?
At present, most of the sizing agent are using the starch and poval in China. Among them, the mixture sizing agent is widely used in the weaving factory, because they have good effect to the weaving. But to the dye and print factory, the mixture sizing agent is harder to desize than the starch slurry and the poval is the most hard to desize. Because its high degree of polymerization, high alcoholysis degree and low water solubility. Take poly cotton fabric for example, the unclear desizing will have a strong impact on the scouring, bleaching, mercerizing, dyeing, printing and treatment. If desizing not clear and then singeing, the top of poly fused to globule, which can mix the compound sizing agent to fiber and make the softening point go down. When in hot-set, the dye agent can get in the fiber in advance and make the sublimation down. When washing in printing, this kind of poly will be polluted easily by reactive dyes and make too much poval in mercerizing lye. Stoppage the pipe when recycle the inspissation, influence the normal work. When dyeing the dark color, some place can not be dyed and the fabric surface may have white cloud maculosus. So the desizing of fabric should be more than 80% and the disabled pulp of fabric should be control under 1%. Sizing is a effective protect measures to the weaving factory, but which is an heavy load to the dye factory. Because of the unclear desizing, the fabric permeate is not good, hard hand feeling, dim color and reduce the processing quality. So the desizing is important. And when the weaving factory choosing the sizing agent should consider of the desizing for dyed factory. Only in this way, can improve the quality of the finished products. By YULONG FR tex

How many method for cotton fabric pretreatment desizing craft?
The sizing agent for gray fabric is came from Textile factory, to improve yarn's weave property, it needs to be added that sizing agent on yarn. Traditional sizing agent have natural starch size and chemical size PVA/PMA/CMC etc. starch sizing have it's great advantage of natural green eco property, and it gradually become the main sizing agent.Sizing agent 's exist have some difficult such as permeate resistant, dyeing chemical material waste, effect follow-up processing and product quality etc, therefore eliminating the sizing process is necessary. Eliminating the sizing process is desizing, desizing have enzyme desizing/alkali desizing/acid desizing/oxidizing agent such multiple method.1、enzyme desizingThis method is using the amylase as the main reactant. Amylase can catalyze starch macromolecular chain hydrolysis, hereby it will generate low molecular compound with smaller molecular weight, lower viscosity, higher solubility, then going through washing , it will eliminate starch sizing . amylase's transition percent conversion, dissolve speed, fit for continuity production, with high efficient, desizing rate reached to 80% up.2、alkali desizingThis method is using sodium hydroxide as the main reaction. Sodium hydroxide cannot using starch dissolved, but it can make the starch puffing severely, make the intermolecular distant enlargement, structure loosen: meantime it will also make the starch and cotton fiber 's hydrogen bond among hydroxyl destroyed, thereby making the adhesive force of starch on cotton fiber decreased, provide it's dissolution ability away from cotton fiber, make it's water solubility increased, then going though water wash, the starch will be eliminated.3、acid desizingThis method using acid and alkali as the main reaction agent. Dilute sulphuric acid will cause water dissolution under suitable condition, and translate to solubility starch, saccharides mixture, these water dissolution component 's water solubility higher, based on from cotton fabric washing. Usually pad-batch process desizing agent made from vitriol and surface reactive agent. Acid desizing fiber have certain damage.4、Oxidizing agentThis method is using hydrogen peroxide/sodium hypochlorite and peracetic acid as the main reaction agent. Oxidizing can make the sizing agent oxidative degradation, not only make the water solubility increase, but also the lotion vicidity decrease, and it's easy make the sizing wiped off. Hydrogen peroxide /sodium hypochlorite and peracetic both are powerful corrosivity oxidizing agent.By YULONG tex
Is fabric a natural material?
'Fabric' is a general name for some sort of cloth. It can therefore be made out of natural or man made materials. Cotton fabric would be an natural material Rayon fabric would not be a natural material Tweed is a fabric which is a natural material. The process of making fabric from a fibre is of cause not a natural process.
