Textile auxiliaries enhance fabric quality, efficiency, and functionality across dyeing processes. As eco-friendly innovations rise, they redefine sustainable textile production while meeting global standards."

What are textile auxiliaries?

Textile auxiliaries are an important part of the modern textile industry. They can not only improve the quality of textiles, but also modify and beautify them. In the chemical processing of textiles, textile auxiliaries, as an indispensable auxiliary chemical, are widely used in the pretreatment, dyeing, printing and finishing of textile dyeing and finishing, shortening the processing process. Dongguan Kefeng Textile Auxiliary Industrial Co., Ltd. aims to improve production efficiency, save energy and water, reduce production costs, improve the special functions and styles of textiles, and increase the added value of the final products for customers. The research and development of textile printing and dyeing auxiliaries is of key significance.

The process of textile printing and dyeing

The main process of textile printing and dyeing is divided into 3 steps:

Pretreatment:

From the previous high alkali, high water, high temperature, phosphorus content to the current low alkali, biological, low water, low temperature, cold stack, phosphorus-free technology, not only reducing sewage discharge, but also greatly reducing production costs, saving labor and electricity gradually become a reality, so the refined, penetrating, and stable printing and dyeing auxiliaries are no longer the previous chemical components containing phenols, benzene, phosphorus, etc., but a new concept of environmentally friendly chemicals, fully satisfying the new concept of life, production technology, and the new concept of international environmental protection. Precisely because of this demand, pretreatment printing and dyeing auxiliaries have undergone a revolutionary change.

Dyeing and printing:

As everyone knows, dyeing and printing technology is the main source of water pollution, so reducing the discharge of dye waste liquid and promoting the absorption of dyes to fabrics as much as possible has become the key to technical improvement. This requires dyeing and dyeing auxiliaries to satisfy the need to add less dyes without affecting the dyeing depth on the one hand, and not increase the dyeing cost on the other hand, and also promote the dyeing fastness. Therefore, new dyeing and printing auxiliaries have to be used. The starting point of the research and development of dyeing and printing auxiliaries focuses on these three aspects, and then dyeing and printing auxiliaries have leaped into a new era.

Post-finishing:

The post-finishing link of textile printing and dyeing is a relatively less polluting process. Therefore, this technology needs to focus on its functionality, safety and environmental protection, beautiful and comfortable, stretch and breathable, smooth and bright, etc. Functional requirements, anti-wrinkle from the former formaldehyde to the current formaldehyde-free, color fixing from the original formaldehyde to today's formaldehyde-free, soft type from the former water-repellent amino silicone to the current hydrophilic polyether block, from yellowing to non-yellowing, from high cost to low cost, from non-environmentally friendly to environmentally friendly, etc.

Current situation of dyeing and printing auxiliaries

Textile auxiliaries are necessary chemicals in the production and processing of textiles. Textile auxiliaries play an indispensable and important role in improving the product quality and added value of textiles. They can not only give textiles various special functions and styles, such as softness, wrinkle resistance, shrinkage resistance, waterproofness, antibacterial, antistatic, flame retardant, etc., but also improve dyeing and finishing processes, save energy and reduce processing costs.

Current situation of textile auxiliaries

There are about 2.000 textile auxiliaries manufacturers in my country, most of which are private enterprises (8-10% are joint ventures and wholly-owned enterprises), mainly concentrated in Guangdong, Zhejiang, Jiangsu, Fujian, Shanghai, Shandong and other provinces and cities. The textile auxiliaries produced in my country can meet 75-80% of the domestic textile market demand, and 40% of the domestic textile auxiliaries are exported abroad. However, there is still a large gap between domestic textile auxiliaries and international advanced levels in terms of variety and quality, as well as synthesis and application technology. Special and high-end textile auxiliaries still have to rely on imports.

With evolving eco-tech, textile auxiliaries drive the industry toward greener, smarter production. Investing in R&D bridges the gap between domestic capabilities and global demands.
