The development process of organic silicon softener

         Because the main chain of the organic silicon is -SI-O-, the molecular chain is softer than the -C-O-chain, and the molecular chain is softer and has excellent lubricating and soft performance. It has been widely used in the sorting of textiles. The development process has gone through the following three stages.

         As early as 1940, Patnode, the United States, published a patent report with dioma -based dichloropenne -treated fiber. In 1945, the United States GE) Elliott and other compositions were soaked in fiber in alkaline aquatic solutions with methyl silicol glycol sodium. After heating, the fiber had a good waterproof effect. In the early 1950s, the US Dow Corning Company found that the use of SI-H-containing hydrogen-containing silicone-containing sircotic fabrics had a good waterproof effect and good breathability, but the feeling of poor hand and silicon film After falling off, it will be used in parallel with polymailing siliconane (PDMS), which not only has a good waterproof effect, but also feels soft. Since then, although Organic silicon products such as Europe, the United States, and Japan have developed rapidly and have a lot of products, they basically belong to the mechanical mixture of dizen -based silicone oil, which is collectively referred to as silicone oil products, which is the first generation of organic silicon fabrics. Di metacopic silicide (DMPS) is the representative of the first generation of organic silicon soft agents.

        Polyxane with high molecular weight of the end hydroxyl group is long considered as an ideal fabric soft agent. In order to facilitate use, it is generally made into emulsion. In 1959, HYDE, etc. of the United States Dow Corning, first applied for a patent of the emulsion polymerization directly to produce hydroxyl silicone oil. It was not until 1969 that the company's WEYENBERY published a research report on Siliconane Ecessal aggregation. In 1972, Rocks published the application report of the sorting of the fabric compilation with the corrected silicide lotion emulsion of the emulsion polymerized hydroxyl seal. In 1976, the company announced the successful development of DC-111 hydroxyl silicon oil emulsion and its application reports on the soft collation of fabrics. The hydroxyl silicon oil emulsion is different from the mechanical mixed lotion. It is a codoniculous lotion with good stability and strong adaptability. It can improve the fabric tolerance and improve it. Subsequently, a variety of types of hydroxy silicon oil emulsion applied to fabrics were successively developed, all of which belong to the second -generation organic silicon fabric soft agent.

       Due to the single function of the second -generation organic silicon soft agent, it is easy to break the milk and drift oil in the use, and organic silicon workers at home and abroad are competing to develop the third -generation silicon soft agent, which is the modified organic silicon soft agent. This type of product is to introduce various active groups such as amino, epoxy, polyether, hydroxyl groups such as amino, epoxyl, polyether, and hydroxyl groups to greatly improve the tolerance, anti -shrinkability, hydrophilicity, etc. The group gives different styles of fabrics. At present, people's research on organic silicon soft agents is mainly concentrated on third -generation organic silicon products.

Among the three generations of organic silicon soft agents, the first generation of soft agent is generally mixed with the second -generation and third -generation soft agents or other types of soft agents and additives. The most mature and widest category of applications; some of the third -generation products have matured, but some are still under research, improvement and development.
