Abstract

The invention relates to a finishing technology for a viscose-type fabric. The aim is to provide the finishing technology for efficiently improving the wet-state tearing strength of the viscose-type fabric. The fabric finished through the finishing technology is soft in handfeeling, the wet-state tearing strength is obviously improved, and the wet-state tearing strength of the viscose-type fabricis greatly improved. According to the technical scheme, the finishing technology for efficiently improving the wet-state tearing strength of the viscose-type fabric comprises the successive followingsteps of 1, resin finishing, wherein the fabric is soaked in water and enters a formation machine rolling groove, and a resin finishing solution is prepared; the mass percentage of resin in the resinfinishing solution is 3-15%; the viscose-type fabric is subjected to finishing solution padding through the formation machine rolling groove, and the roll-over rate keeps within 60-90%; then drying isconducted through a formation machine, the drying temperature is 160-180 DEG C, and the drying time is 60-150 s; 2, softening finishing, wherein a softening agent and water are mixed and prepared into a softening finishing solution, and the solution is added to the formation machine groove; the mass percentage of the softening agent is within 1-6%.

Description

technical field [0001] The invention relates to a finishing process for viscose fabrics, in particular to a finishing technique for efficiently improving the wet tearing strength of viscose fabrics. Background technique [0002] Viscose fiber is a cellulose fiber. It is made of natural fibers (wood fibers, cotton linters) as raw materials, through alkalization, aging, sulfonation and other processes to make soluble cellulose xanthate, and then dissolved in dilute lye to make viscose. made by spinning. [0003] The breaking strength of ordinary viscose fiber is smaller than that of cotton, about 1.6-2.7cN / dtex; the elongation at break is higher than that of cotton, which is 16%-22%. Its modulus is lower than that of cotton, it is easy to deform under a small load, and has poor elastic recovery performance, so the fabric is easy to elongate, has poor dimensional stability, and is not washable. The strength and wear resistance of viscose fiber in wet state are worse, the wet...
