Comprehensive Analysis of Softening Agent for Textile Auxiliaries Chemicals
Time: Click: 1160
Softening agent is a material which can be adhered to the surface of the fiber and make the fiber become soft so that to improve the sense of feel and touch. Softening agent can not only make the textile soft but also has the effects of antistatic, anti-pollution, improving smoothness, tearing strength and improving sewing. HT FINE will have a test and analysis towards all kinds of textile softening agents to have a comprehensive conclusion for you!
The requirements of textile softening agents
They should have excellent softness、smoothness and bulkiness.
They should have a small effect to the whiteness and color fastness of textile.
They should have a great stability when they are under varieties of deep—processing conditions(impregnation, dip rolling, temperature, PH, etc.)
Soft finishing of fiber or fabric should not be in heat discoloration, and the storage should not produce the changing of color, odor, feel.
If the softener is the emulsion, the stability of its emulsion should not be broken.
When they have contact with skin, they will not do harm to it, which should meet the requirement of the environment.
According to different handling requirements: they should possess the properties of water absorption, water repellency and antistatic.
How to distinguish the softening agent?
Softener is one of the most popular auxiliaries in dyeing and finishing. According to its chemical structure, it is basically two kinds of long chain fatty group or macromolecule polymer.
The long chain fatty race is not only of many varieties but also of a large amount. These softeners can be classified into anionic, cationic, nonionic, and zwitterionic is based on their ionic properties.
Besides, for natural oils and waxes, softeners are natural lubricants, and can also be used as a separate class. Polymer softener mainly has polyethylene and silicone. The varieties of polyethylene softener are single, and the dosage is less. The main used one is the silicone softener.
The molecular structure of polysiloxane alone can reduce the static and dynamic friction coefficient between fibers as well as reduce the surface tension of fibers. It is an ideal material for softening finishing agents of textiles.
Silicone softeners, especially amino modified silicone softeners, are the fastest growing soft one in recent years.
