Abstract

The invention relates to the technical field of a fabric softening finishing method, and particularly relates to a nylon fabric slight-plasticizing softening finishing method. The finishing method comprises the steps of enabling a nylon fabric to be added into a diammonium hydrogen citrate solution for soaking treatment; putting the pre-soaked nylon fabric into a softening finishing agent for soaking, wherein the softening finishing agent comprises 5.0 to 10.0 parts of amino silicone oil, 5.0 to 8.0 parts of hydroxyl-terminated polysiloxane emulsion and 35 to 50 parts of water; and taking outthe soaked nylon fabric to be processed by a padding machine for two times, and then carrying out drying and shaping. The problem in the prior art that after the nylon fabric is processed by the softening finishing agent, the finishing agent is relatively weak in adhesive force on the nylon fibers and is not resistant to washing is solved; and by enabling the diammonium hydrogen citrate solution to be dissolved into water to be used a pre-soaking solution, the diammonium hydrogen citrate permeates and inserts into the nylon fibers to enable the nylon fibers to be slightly plasticized, and permeation and adsorption of amino silicone oil and the hydroxyl-terminated polysiloxane emulsion on the nylon fibers are implemented conveniently, so that the softening finishing agent can be firmly attached to the nylon fabric to improve the washing resistance.

Description

technical field [0001] The invention relates to the technical field of fabric softening and finishing methods, in particular to a method for slightly plasticizing and softening nylon fabrics. Background technique [0002] Polyamide fiber is commonly known as nylon, that is, nylon (Nylon). The hygroscopicity of nylon fabric is better among synthetic fabrics, so clothing made of nylon is more comfortable to wear than polyester clothing. In addition, nylon fiber material, as one of the main fibers of textile fabrics, is widely used in daily life due to its excellent wear resistance and elasticity, such as stockings, underwear fabrics, mountaineering suits, etc. Although nylon fiber has many advantages, it is less flexible than natural fibers. As a clothing fabric, it also needs to be flexible. [0003] Softening refers to the techniques commonly used in the dyeing and finishing process of textiles. Softeners are usually used to reduce the coefficient of friction between fib...
