What are the types of textile softer agents?

Textile softer agent effect

1. Supplement the natural oils lost in the process of fine and bleaching, make the feel more ideal.

2. Attach on natural fibers or synthetic fibers, improve smoothness and strength, and improve the feel.

3. Improve the performance of the fabric through some characteristics of the soft agent.

In order to achieve the above functions, the soft agent is generally a matter of smoothness and feel of oil and fat. Attachment on the fiber surface can reduce the friction resistance between fibers and make the fiber lubricate and soft. There are also some soft agents that can meet with some reaction groups on the fiber to achieve the purpose of washing.

Types of softer agents

The soft agent is the one with the most varieties and the largest amount of dyeing auxiliary agent. According to reports, of the 920 domestic and foreign auxiliary samples collected from the Shanghai Printing and Dyeing Technology Research Institute from 1990-1999, 350 soft agents were samples, accounting for 38 %. According to its chemical structure, so many soft agents are basically two categories: long -chain fat or polymer polymers. The hydrocarbon long chain in the long -chain fatty soft agent molecular structure can be arranged irregularly, forming molecular softness. The molecular molecular adsorption on the fiber surface play a lubricating effect, which reduces the fiber and the fiber and the fiber and the fiber. Fiber's movement and static rubbing coefficient.

Therefore, the long -chain fattened structure generally has a good soft effect, not only in the soft agent, but also a large amount. This type of soft agent can be divided into anion type, cationic type, non -ions and bisexual types according to its ionic nature. In addition, for natural oils and paraffin soft agents, because they are all natural lubricating substances, they can also be used as a separate category, but they also attribute them to different ionic categories according to the different ion properties of emulsion agents, respectively. Essence The polymer polymer soft agents mainly include polyethylene and silicon. The varieties of polyethylene soft agents are relatively single, with less dosage and less dosage. The main use of more organic silicon soft agents. Because the main chain of polysilicine is a spiral -shaped straight -shaped straight structure, it can rotate freely at 360 degrees, and the energy required for rotation is almost zero. Therefore, the molecular structure of polysilicine solid objects conforms to the soft mechanism of textiles, which can not only reduce the static and dynamic friction coefficient between fibers, but also to reduce the force between the molecularity and reduce the surface tension of the fiber. Ideal materials. Silicon soft agent is the fastest -growing soft agent variety in recent years.
