Softener for textile industry


Softening agents for the textile industry can be used as textile auxiliaries. They can change the touch feel of textiles, they give a more comfortable sense of touch. At the same time, they also have other roles. For example, when the loose fiber dyeing, it makes the fiber spinning and weaving process smoothly after the application. this actually linked to the soft composition of various other properties such as eliminating static electricity, absorbs water and so on.

Here are some requirements about softener:
1 It has excellent softness, smoothness, fluffy.
2 Has little effect on the whiteness and dyeing fastness of the fiber or fabric.
3 During the various processing conditions (impregnation, padding, changes in temperature, PH, etc), the working fluid requires a reasonably stability.
4 It is not suitable for heat discoloration after softening finishing of fibers or fabrics. It should not have colour, odour and texture changes during storage.
5 If the softener is emulsion, the emulsion stability requires good.
6 According to different requirements, it has appropriate absorption capacity, water repellent, anti-static properties, etc.
7 There is no adverse effects after skin contact, it meets the requirements of environmental protection.

Soft finish is an important finishing processes of dyeing and printing process. During textile processing, it may become rough after processing many times. Generally, synthetic fabrics less good, especially the microfiber fabric. In order to make the fabric has a soft, smooth, comfortable feel, it needs to finishing it, so softener for finishing is widely used.

In addition, there are heavy use of softeners in the process of various chemical fiber spinning, fiber spinning, weaving and so on. That is because speed and low bath ratio of heavy use in the textile processing, this increases friction between the fabrics, and friction between fabric and device. Use softener to make the fiber itself is commensurate with the condition of soft and smooth to avoid injury. As a result, fabric softener is one of the most important Textile auxiliaries.

Textile auxiliary for textile processing


Textile auxiliary is the necessary chemicals in the textile processing. It plays an important role in improving the quality of textile products and added value. It can not only give textiles a variety of special features and styles, such as soft, wrinkle, shrink-proof, waterproof, antibacterial, antistatic, flame-retardant and so on, but also improve the dyeing and finishing process, as well as can save energy and reduce processing costs.

About 80% surfactants as raw material, and 20% are functional. After more than half a century of development, surfactant industry all over the world is mature. In recent years, textile production center have turned from Europe, the United States gradually shifting to the Asia, making rapid demand growth in the Asian region.

Textile dyeing and textile finishing auxiliaries for textile processing plays a very important role in the process. Although the use amount is little, but it plays an important role in the textile processing. In summary, the textile dyeing and finishing auxiliaries mainly plays the following roles in the textile products processing.

1 shorter processing cycles or fewer processes, this saves processing time and improve the processing efficiency
2 reduce energy consumption, save energy and reduce costs
3 reduce pollution and improve the quality of environment
4 improving the dyeing effect and fabric appearance and inner quality
5 give textiles a particular function and effectiveness, improve product performance and added value

According to the material composition, textile auxiliary can be divided into surface active additives and non-surfactant additives. There are a large part of textile dyeing and finishing auxiliaries are made up of surfactants. It approximately accounts for more than half of all auxiliaries. Part of itself is pure surfactant, and more that contain surfactants and their mixtures, such as emulsifiers, wetting agents, detergents, etc; Non-surfactant contains no surfactants in dyeing and finishing auxiliaries. It consists of polymer compounds and other organic and inorganic composition, such as resin finishing agents, flame retardants, fluorescent brightener.

Improve the overall competitiveness of the industry, develop ecological development and environmental protection, improve product quality and technical level is the key to sustainable development. Downstream customers of Textile auxiliaries dyeing factory in China is still fragmented. With the increasing of environmental pressures, it will speed up industry consolidation, and the future trends will be concentrated. Accordingly, the textile industry centralized to dominant businesses with good technology and service. If you have interest, please click here!
