1、 Permeation effect

Due to the large amount of pectin produced during the growth process of cotton, which is distributed on the primary wall of the fiber interface, it hinders the moisture absorption of its inner wall. At the same time, due to the high surface tension and poor permeability of the NaOH solution, the refining agent can effectively reduce the surface tension of the solution, allowing the fiber to have better contact with the refining solution and accelerating wetting and penetration.

2、 Cleansing effect

The cleaning process of refining is relatively complex. Firstly, it is necessary to reduce the adhesion between wax and oily substances on the fabric and the fabric, so as to facilitate the mechanical removal of oil stains from the fabric. On the other hand, it is necessary to quickly disperse the decomposition products of alkali action to prevent further pollution.

Since the main components of scouring agent are anionic and non-ionic surfactants, a large amount of foam will be produced. The overflow of foam not only wastes the auxiliary agent, but also affects the scouring effect, bringing trouble to the production. In order to solve this problem, the method of adding defoamer is often used to reduce the production of foam. The application of defoamer in polyester dyeing process is very mature, but there are many problems in the application of cotton fabric. On the one hand, high temperature and high PH have very high requirements for defoamer. In addition, the nozzle of knitted fabric has a strong jet force when it is scoured in the overflow machine, and the defoaming effect is usually good at the beginning, but after a long time, the effect will decline, and foam will be produced again, that is, the foam suppression effect is not strong, as shown in the figure below.

3、 Solution

In order to fundamentally solve the above problems, our company has prepared a new scouring agent TY-109D, which can be directly used for low foam degreasing scouring of knitted fabrics and yarns. At the same time, because of its special structure, the product has a slight foam generation at 35 ℃, and has its own defoaming effect above 35 ℃, without foam generation.
