In the field of textile finishing, a long-standing contradiction exists between soft hand feel and hydrophilic performance. Although traditional amino silicone oils can impart an extremely soft and smooth feel to fabrics, their strongly hydrophobic molecular structure severely impairs the moisture absorption and sweat-wicking performance of fabrics, resulting in a stuffy and uncomfortable wearing experience. Zhejiang Kefeng Silicone Co., Ltd. (Kefeng Silicone), as a leading enterprise in China's block silicone oil field, has leveraged over twenty years of industry深耕 and strong research and development capabilities to launch its Durable Hydrophilic Silicone Oil Finishing Agent series, successfully breaking through this industry technical bottleneck.
Through precise molecular design and compounding technology, this product organically integrates the soft and smooth characteristics of block silicone oil with the hydrophilic function of polyether segments, providing a comprehensive solution that combines ultra-soft hand feel, excellent hydrophilicity, and durable finishing effects for cotton, polyester, blended fabrics, and various fiber materials.
Zhejiang Kefeng Silicone Co., Ltd. was established in 2002 with a registered capital of 60 million RMB. It is a national high-tech enterprise focused on the research, development, production, and sales of textile printing and dyeing auxiliaries and nano liquid disperse dyes. The company operates three major production bases in eastern and northern Hangzhou, as well as in the Quzhou Green Agglomeration Zone (a national-level chemical park). Its monthly production capacity of block silicone oil crude reaches 1,000 tons, demonstrating strong large-scale production capacity and supply chain stability.
Kefeng has particularly deep technical accumulation in the field of hydrophilic silicone oils. The company holds 16 patents for textile hand-feel auxiliaries, and all products have passed ZDHC MRSL Level 3.1 certification, ensuring compliance with the highest international environmental standards. In 2022, the company invested more than 30 million USD to establish a new production base with an annual capacity of 100,000 tons of textile hand-feel auxiliaries in Dongguan, Guangdong Province, further consolidating its leading position in the industry.
Traditional amino silicone oil is the most widely used organic silicone material in textile softening finishing. Its active groups can bind well with fiber fabrics, imparting a soft, smooth, and fluffy hand feel. However, amino silicone oil has several inherent drawbacks: poor emulsion stability, easy roller sticking, tendency to yellow at high temperatures, and most prominently — strong hydrophobicity, which causes fabrics to almost completely lose their hydrophilic performance after finishing.
Kefeng's Durable Hydrophilic Silicone Oil Finishing Agent represents a new generation of block silicone oil technology. Its molecular chain is formed by polysiloxane segments and polyether segments connected alternately through block copolymerization. This structural design brings revolutionary performance breakthroughs:
Polysiloxane segments impart excellent softness, smoothness, and fluffiness to fabrics — the core value of silicone oil finishing agents. Polyether segments provide hydrophilicity and antistatic performance, enabling finished fabrics to quickly absorb moisture and conduct and diffuse it, restoring the fiber's inherent moisture absorption and sweat-wicking function.
The reason this product is called a "durable" hydrophilic silicone oil finishing agent stems from its unique molecular architecture. Unlike traditional side-chain hydrophilic silicone oils (where polyether segments hang from the side of the main chain), Kefeng's block silicone oil places polyether hydrophilic segments on the main chain of the polymer. This structure allows hydrophilic segments to directly interact with the fiber surface rather than extending outward from the fiber, thereby significantly improving the wash resistance of the finishing effect.
At the same time, the block structure gives silicone oil molecules stronger self-emulsifying ability, enabling them to form a more stable and finer dispersion system in the aqueous phase, fundamentally reducing common problems such as emulsion breaking, oil floating, and roller sticking associated with traditional silicone oils.
Fabrics treated with this finishing agent can achieve instant water absorption — the absorption time of water droplets on the fabric surface can be controlled within 3 seconds. This performance is crucial for products requiring good moisture absorption and sweat-wicking functions, such as intimate apparel, sportswear, towels, and home textiles. Finished fabrics can quickly absorb sweat and conduct it to the fabric surface for evaporation, significantly improving wearing comfort.
While achieving excellent hydrophilicity, this product does not sacrifice the core value of silicone oil finishing agents — soft hand feel. Finished fabrics possess a soft, smooth, fluffy, and full tactile quality, with hand-feel ratings at the leading level in the industry. The introduction of polyether segments not only does not weaken the softening effect but actually makes the hand feel more natural and delicate by improving the spreading property and film-forming uniformity of silicone oil on the fiber surface.
Traditional amino silicone oils are prone to yellowing during high-temperature setting or long-term storage, significantly affecting the appearance quality of white and light-colored fabrics. Kefeng's block hydrophilic silicone oil significantly reduces the tendency to yellow through molecular structure optimization, making it suitable for finishing white, light-colored, and high-whiteness fabrics.
This product possesses multiple stability characteristics including high temperature resistance, acid and alkali resistance, electrolyte resistance, and high shear resistance. In actual production, this means the finishing liquor is not prone to emulsion breaking or oil floating during long-term operation, does not stick to rollers or tanks, and reduces production failures and fabric defects caused by unstable finishing agents. Additionally, this product has good compatibility with cationic/non-ionic softeners and can be adjusted to achieve different hand-feel styles as needed.
A frequently overlooked but extremely practical feature is that if the color is found to be unsatisfactory after finishing, direct re-dyeing can be carried out without removing the softener. The finishing agent does not affect subsequent dyeing results, and dyed colors are deep, pure, and vivid. This characteristic provides printing and dyeing mills with great process flexibility and error tolerance.
This Durable Hydrophilic Silicone Oil Finishing Agent is widely suitable for soft and hydrophilic finishing of various fiber materials, particularly for the following application scenarios:
