Defects in Early Application of the Soft Finishing Agent

1. The use rate of soft finishing agent has increased


Among textile printing auxiliaries, softening agents are a large category in finishing auxiliaries, with many varieties and large output. From spinning, drawing, reeling, weaving of chemical fibers, or slivering, spinning and weaving of cellulose fibers to the dyeing and finishing of textiles, a large amount of soft finishing agents are used in various processes. Various types of the soft finishing agent can give fabrics different feel and styles. With the changes of the times, their applications are not only limited to the applications in the textile industry, but are gradually moving towards the daily chemical washing industry, which is becoming more and more accepted and used by ordinary families.


2. Early application of soft finishing agent


In the early days, soft finishing agents represented by various amino silicone oil emulsions were widely used in the finishing process of cotton, silk, wool, polyester and other textiles to give the fabric a soft and smooth feel. It is comfortable to wear which is once widely accepted. The rapid expansion of the application of amino silicone oil far exceeds that of any other silicone products. It plays the role of the leader in the textile processing process and is a product that is inseparable from the soft processing of factories.


However, with the continuous improvement of human living standards, and the advocacy of green life, skin-friendly and comfortable styles, the water repellency and poor air permeability of the fabrics after amino silicone oil finishing has been highlighted, and the light-colored or white fabrics after finishing have undergone high temperature. After baking, the shortcomings of varying degrees of yellowing will appear.


This is mainly determined by its structural changes and the amino modification of hydrophilic silicone oil. As the use continues to expand, problems in the application are constantly exposed, which is easy to yellow and change color, easy to float oil, and not hydrophilic. Because of these major problems, the factory is both willing to use it but also afraid of problems, and is always worried during the production process.


In order to overcome these shortcomings, various methods were used to modify, and finally a series of ternary copolymerized hydrophilic silicone oils were introduced, including polyether modified and quaternized modified ternary copolymerized hydrophilic silicone oils to highlight the style of hydrophile, ice feeling, comfortable, slippery and skin feeling.
