International ClassesD01G 21/00D04H 1/46 AbstractA method for producing spunlace non-woven cloth includes the following steps: clearing cotton—carding—spreading the web—water jetting—bleaching—drying—rolling the finished products. This method improves the good ratio of the finished products of the whole procedure, reduces the producing cost, economizes raw materials and save the power as well as reduces the impurity content of products and ensures the hygiene of finished products and greatly reduces the bacteria content. Moreover, the direct products of the present invention have the advantages of being soft, having good skin tolerance, no toxic, no stimulation, no sensibility, having good absorbency, convenient and comfortable to use.Field of SearchBy fluid jet needling or perforatingThrough backing and support members Fiber entangling and interlocking Cross laying by rotatable or revolving flyer Cross laying by divergent thread conveying members Treating By pretreatment of component By fluid contact Fluid or special treatment Cleaning And feeding Cotton conditioning Carding Feeding Systems Web forming Combing WORKING BLEACHING CLEANING OR LAUNDERING Degumming or desizing Running lenghts | |
