Innovative process for hydrophilic silicone oil additive, meeting the new demands for comfortable finishing of knitted fabrics 

1. The shortcomings of traditional silicone oil finishing are becoming more prominent, and the problem of matching with knitted fabrics urgently needs to be solved.
Currently, the consumption of knitted clothing and home knitted fabric markets is continuously increasing. Consumers not only require a soft and smooth touch for the fabric, but also value the wear experience of moisture absorption, breathability, skin-friendly and no excessive sweating. Although conventional textile silicone oil additives can create a basic soft effect for knitted fabrics, the inherent formula and process have obvious shortcomings. There are generally problems such as overly strong film-forming ability and blocking of fabric fiber pores. After the fabric is finished with conventional silicone oil, although the touch meets the standards, the breathability significantly decreases. The wear is hot and sticky, and the moisture absorption and sweat release performance deteriorates. After washing, it is prone to problems such as hard touch, fabric stickiness, and local wrinkling, which cannot meet the production standards for essential categories such as spring and summer knitted items and close-fitting underwear. The industry urgently needs a new type of silicone oil finishing solution specifically for knitted fabrics. 

2. The development of a new type of composite hydrophilic silicone oil has been successfully completed, and the core formula has been precisely optimized. 
The textile auxiliaries industry has targeted the characteristics of knitted fabrics and completed the formula research and batch trial production of the new type of composite hydrophilic modified silicone oil auxiliaries. This research abandoned the traditional single amino silicone oil blending mode and adjusted the ratio of silicon oil molecular chains, added hydrophilic functional groups embedded in the modification process to balance the softness and lubricity characteristics of the silicone oil with the dual requirements of fabric hydrophilicity and breathability. The new formula does not add extra film-forming auxiliaries and focuses on flexible adhesion to the surface of fibers rather than full coverage film formation. It retains the fluffy and soft texture of the silicone oil while not blocking the warp and weft weaving pores of knitted fabrics, fundamentally solving the industry's old problem of being unable to balance softness and breathability. It is suitable for various mainstream fabric substrates such as cotton knitted, blended knitted, and recycled fiber knitted fabrics. 

3. The practical operation results show excellent performance in fabric finishing, and the overall quality of the fabric has been comprehensively upgraded.
After batch fabric industrial finishing tests, this new hydrophilic silicone oil additive has achieved a comprehensive performance far exceeding that of traditional similar products. After the fabric is treated with this additive, the hand feels fluffy and soft without being greasy. The smoothness is naturally not stiff, and the fabric's moisture absorption rate has increased by nearly 30%. After washing, it dries quickly and does not stick to the skin. After repeated washing for 30 times, the fabric still maintains its original soft texture, without hardening, static electricity generation, yellowing, or whitening. The retention rate of fabric elasticity remains at a high level. At the same time, the hydrophilicity of the finished knitted fabric has significantly improved. It adheres to the skin without any irritation, fully meeting the safety wearing standards for close-fitting clothing and baby knit products. There are no allergenic risks. 
With the popularization of the concept of healthy and comfortable consumption among the general public, the quality improvement and upgrading of close-fitting knitted textiles has become an inevitable trend in the industry. Hydrophilic functional silicone oil additives have become the core essential product in the fabric finishing process. This new hydrophilic silicone oil additive is compatible with large-scale textile production lines. The processing technology is simple and easy to operate, and there is no need to adjust the parameters of the finishing equipment. It does not increase additional production and processing costs. In the future, this type of silicone oil additive will be fully popularized in the regular finishing processes of knitted fabrics, helping the textile industry to create high-quality and comfortable knitted products, meeting the demands of the terminal market, and promoting the transformation of the knitted textile industry from basic processing to high-quality and comfortable high-end development.
