The Study Of Synthesis And Application Of The Low-yellowing And Hydrophilic Silicone Softener

the fabric finished by Conventional amino silicone oil has good flexibility, smooth, flexible, comfortable and washable. However, the finishing of fabric,especially,chemical fiber and blended fabric, Poor moisture absorption, worn by the hot, taking the performance degradation and yellowing of the fabric is easier. The finished fabric by silicone polyether has good moisture absorption, anti-static performance, when wearing the fabric is easy to overcome with static electricity, dust, hot and shortcomings, but the softness and feel relatively poor. To solve the above problems, comprehensive amino silicone oil and the advantages and disadvantages of silicone polyether, The subject of the bulk polymerization method used, the end of the introduction of hydrogen silicone oil in the main chain amino group of polyether and Asia to prepare a low-yellowing hydrophilic silicone softener. Since fabric softener after finishing the ordinary, feel, and there is contradiction between the two hydrophilic, the subject of low-yellowing synthetic hydrophilic silicone softener, fabric handle and can be hydrophilic to ensure good premise, has greatly improved the fabric of the yellowing phenomenon.1. By bulk polymerization approach to hydrogen silicone oil, reactive polyether, and N, N-methylene bisacrylamide as raw materials and toluene as solvent, chloroplatinic acid - isopropanol as a catalyst in the main terminal hydrogen silicone oil The introduction of polyether chains and the amino group of Asia, was synthesized by a low-yellowing hydrophilic silicone softener emulsion.2. The configuration and properties of the low-yellowing and hydrophilic Silicone Softener were characterized by FTIR, TG-DTA, SEM, TEM, Zeta electric potential and particle size analysis.3. Experiments show that: reaction temperature 100℃, reaction time 10h, the amount of catalyst 0.5mg/kg, the material ratio of hydrogen silicone oil: reactive polyether: N, N-methylene bisacrylamide = 1.5:1: 1, the synthesis of low-yellowing hydrophilic silicone softener finishing fabric, the fabric can give a better hydrophilic, low yellowing and good softness and fullness of feeling, is also a good washing resistance.4. Low-yellowing hydrophilic silicone softener finishing polyester fabric softener optimum conditions for the amount of 100 g ? L-1, the curing temperature is 160℃, baking time is 3min.5. Fabric fabrics were treated with low-yellowing hydrophilic silicone softener and high ammonia values can be found after finishing amino silicone oil, low-yellowing hydrophilic amino silicone oil in ensuring the fabric on the basis of ultra-soft, anti-yellowing and pro-Water is also greatly improved, reaching all aspects of dyeing processing requirements.
