1. Introduction to textile printing and dyeing auxiliaries

As additives in textile printing and dyeing processes, textile printing and dyeing auxiliaries are an important part of textile fine product processing. According to their role in the process, they can be divided into pre-treatment auxiliaries, dyeing and printing auxiliaries, and finishing auxiliaries. Finishing auxiliaries can improve the appearance and quality of textiles after the dyeing and printing process, and at the same time give textiles certain special functions, such as antistatic, antibacterial and anti-mildew.

The use of pre-treatment auxiliaries is mainly to remove natural and artificial impurities on textiles, so that they can give full play to the excellent characteristics of textiles to meet the needs of subsequent processes. Pre-treatment auxiliaries mainly include scouring penetrants and emulsifiers.

Dyeing and printing auxiliaries refer to a series of auxiliaries used in the dyeing and printing process in addition to dyes and coatings, mainly including soaping agents, detergents and fixing agents.

Dyeing and printing are important processes in the textile printing and dyeing process, covering dyeing, printing, color fixing and soaping processes. Through dyeing or pattern printing, the traditional monotonous and boring visual effects are changed, giving textiles a beautiful, colorful and personalized effect.

The use of finishing auxiliaries is mainly to improve the appearance and internal quality of textiles through physical and chemical processing, improve the feel, stabilize the shape, improve the wearability or give textiles certain special functions, such as softness, waterproofness, shrinkage prevention, wrinkle prevention, flame retardant, antistatic, mildew and antibacterial, antifouling and oil resistance. During the production or wearing process of textiles, their surfaces are susceptible to different degrees of friction, which may cause static electricity or pilling, affecting the wearability of textiles.

Finishing auxiliaries are used in the finishing process of textile printing and dyeing, mainly through physical and chemical processing, to improve the appearance and internal quality of textiles, improve the feel, stabilize the shape, improve the wearability or give textiles certain special functions, such as softness, waterproofness, shrinkage prevention, wrinkle prevention, flame retardant, antistatic, mildew and antibacterial, antifouling and oil resistance. The main products include segmented silicone oil, etc.

2. Overview of the textile printing and dyeing auxiliaries market

my country's per capita textile consumption is still 20% of that of developed countries. At present, the global textile printing and dyeing auxiliaries center is shifting to Asia and China. my country currently has 3.000 textile printing and dyeing auxiliaries manufacturers and is the world's largest consumer of textile printing and dyeing auxiliaries. my country's textile printing and dyeing auxiliaries production has developed rapidly since the 1990s. According to data from the Textile Printing and Dyeing Auxiliaries Professional Committee of the China Dyestuff Industry Association, China's textile printing and dyeing auxiliaries production reached 2.45 million tons in 2020. an increase of 2.38 million tons from 1982.

Due to the lack of awareness of the importance of textile printing and dyeing auxiliaries in domestic printing and dyeing enterprises, the current consumption level of textile printing and dyeing auxiliaries in my country is still at a relatively low level. The ratio of textile printing and dyeing auxiliaries output to fiber output in industrially developed countries is about 15:100. and the world average is about 7:100. while the current level in my country is only about 4:100. With the continuous improvement of the living standards of the Chinese people, there is still a lot of room for improvement in the consumption level of printing and dyeing auxiliaries in my country.

3. Application and market development of silicone oil in textile printing and dyeing auxiliaries

Silicone oil is mainly used in the textile field in the subsequent finishing stage. Typical products include amino silicone oil, hydrogen silicone oil, block silicone oil and its emulsion made after emulsification, which can be used as fabric softener, fiber smoothing agent, dark processing agent and other subdivided auxiliaries. As the world's largest textile printing and dyeing auxiliaries market, it is estimated that by 2025. the market size of silicone oil crude oil used in textile printing and dyeing auxiliaries in my country will reach 10.8 billion yuan, and its growth will mainly come from the increase in the textile market. As a finishing agent, the market share of modified silicone oil products in textile chemicals is expected to remain stable.

It is estimated that the scale of my country's silicone in the industrial auxiliaries market will reach about 19.2 billion yuan in 2025. with a compound growth rate of 8.17% from 2020 to 2025. At the same time, considering that my country's textile auxiliaries are a self-use + export market, according to the global production of textile printing and dyeing auxiliaries, it is predicted that silicone products will account for about 30 billion yuan in global textile printing and dyeing auxiliaries in 2025.

4. Changes in downstream demand

In the first half of 2022. due to the impact of macroeconomic factors such as the US dollar interest rate hike and the Russia-Ukraine war, the domestic economic recovery has been greatly affected by uncertainties, and the demand in the downstream textile industry has also declined. The following mainly analyzes the downstream industries of printing and dyeing auxiliaries, which are the textile industry and the printing and dyeing industry.

According to data from the National Bureau of Statistics, in 2022. the output of printed and dyed fabrics by enterprises above designated size in the printing and dyeing industry was 55.622 billion meters, a year-on-year decrease of 8.19%. Looking at the whole year, in the first quarter, the production situation of the industry was basically good, and the output of printed and dyed fabrics maintained positive growth. Since the second quarter, factors such as the intensification of the conflict between Russia and Ukraine and the accelerated tightening of monetary policy in Europe and the United States have had a great impact on the terminal consumer market, and the growth rate of printed and dyed fabric production has fallen quarter by quarter. Insufficient total demand is a prominent problem facing the current industry production. In 2022. my country's total retail sales of consumer goods fell by 0.2%, of which the retail sales of clothing, shoes and hats and textile products above the limit fell by 6.5%.

With the orderly recovery of my country's production and living order, offline consumption scenarios have accelerated their expansion. With the support of national policies and measures to stabilize the economy and promote consumption, residents' consumer confidence will be improved, and the domestic consumer market is expected to gradually recover. Consumption will become a key force to drive the economic growth of the industry. According to the data released by the National Bureau of Statistics, the total retail sales of clothing, shoes and hats, and textile products in my country from January to April 2023 increased by 13.40% year-on-year, and the entire downstream market showed a significant recovery trend compared with 2022.

As a necessity industry in people's daily life, the textile industry's products are mainly used in the finishing stage of textile printing and dyeing, which is an essential processing link in textile printing and dyeing. Therefore, although the industry's business is affected by the macro-economy in the short term, in the medium and long term, the sales of products such as segmented silicone oil will gradually resume growth.
