Many uses of softener

The requirements to softener are as follows:

1 with excellent softness, smoothness, fluffy

2 little influence on the whiteness of the fiber and fabric, as well as dyeing fastness

3 the working fluid has a reasonably stability during the processing of various soft conditions (impregnation, padding, changes in temperature, PH, etc)

4 after softening finishing of fibers and fabrics is not suitable for heat discoloration, it should not have colour, odour and texture changes during storage

5 if the softener is emulsion, the emulsion stability to better

6 no adverse effects after skin contact, in line with the requirements of environmental protection

7 according to different requirements, they should have appropriate absorption capacity, water repellent and anti-static properties

Use of softener



Softening agent in the application can use the padding method, exhaust dyeing method. Sometimes in the dye bath and dye at the same time; sometimes , it is added after the dye over and cooled, also it is added in the cleaning bath.

During soft processing, effective ingredients of fiber general is controlled in 0.5~7.0%, processing of temperature makes cation soft agent easy adsorption, due to the big polar of fiber and the soft agent basic raw materials. So when it controlled in 70 ℃ around, anion softener is on the contrary to cation system, then it is difficult adsorbed by fibers. Non-ion softener is not influenced by processing temperature, so soft processing can be handled at room temperature.

Acrylic fibers containing anion radicals, so it usually by dyeing with cationic dyes. Generally they are treated by cationic softener, so it has little effect on color. Meanwhile, as the fibers with anionic radicals, softeners have good adhesion.

Cellulose fibers, such as treated by direct dyes and anionic brightener. Many factories are using anionic softeners to avoid affecting color. But when the cotton fibers dye with a solid dye such as restore, curing and active dye, cationic softener treatment available. Softeners should be carefully selected to avoid yellowing and seriously affect the absorption capacity. If you have interest, read more here, thanks!

Use of textile softener

Textile softener is a large class of finishing auxiliaries in textile auxiliaries. From chemical fiber spinning, stretching, drum, woven or cellulose fibers business, spinning, weaving and dyeing and finishing of textiles, they all need to use softener.

Its main function is to satisfy the different feel of various textile, different styles and different requirements. After dyeing of cotton, fiber, bulk hair and various mixed fiber, it needs to use softener to improve weaving performance. Processed garments need to use softener after finishing to ensure that the garment has a good feel. With modern living standards improve, softener use has reached a domestic washing process.



There are two main categories of textile softener products:
1 Aliphatic type (non-SI): dominated by cationic, and nonionic, anionic, and amphoteric.
2 Silicone type: the first generation of methyl silicone oil emulsion. Second generation of D4 siloxane emulsion polymerization, also called hydroxy lotion. Third-generation D4 silicone and silane coupling agent bulk polymerization, emulsification again, products have LaTeX, transparent liquid (called micro-emulsion), high concentration of Silicon oil (50%) (80%), and so on.

Softeners generally are used during after processing for textile products. For example, add softener to dyeing and finishing processing can make the fabric feels better. Also, use softeners before ironing of cardigan is the same purpose.
Fabric softener is a kind of daily chemical products that give clothing and fabrics in dress a sense of soft. With the development of synthetic detergent, it gradually enter into ordinary families and become a daily washing care from the textile industry. Fabric softener can be used in detergency process or in the rinsing phase or in the drying process.

The main active ingredients of fabric softener is cationic surfactants. Based on its structure, it can be divided into alkyl quaternary ammonium salts quaternary ammonium and alkyl imidazoline-type. Its basic principle of soft fabric with different degrees of negative charge. When Ionic surfactant come across these fabrics, through a combination of positive and negative ions of the chemical and physical effects, it can quickly adsorbed on the surface. Its hydrophilic groups connected to the fabric, and hydrophobic outwards. Because of the long hydrophobic groups, it forms the slip surface between the ends. This can effectively reduce the coefficient of friction on the surface of the fabric, and makes the fines fibers return to the body, so that the dry fabric with a soft and smooth feel. Fabric fibers on the market can be divided into wool, silk, cotton, blends and polyester. In these different types of fiber, the adsorption of cationic surfactants are very different. This also result in different kinds of fabric using fabric softener have different effect. Get more!
