Problems solved by technology

The commonly used polyester-polyether multi-block binary copolymer is used in the post-finishing method of fabrics, which makes the fabrics have good hydrophilic and antistatic properties, but the fabrics have poor hand feeling, and then use amino-modified silicone oil emulsion to treat the fabrics. Soft finishing, but its cross-linking with the fabric to form a film is not easy to remove, and the repair performance is not ideal; the patent No. is the polyester polyether polyoxysilane terpolymer fiber disclosed in the CN1069086 patent. The softness and smoothness of polyester fabrics, but the hydrophilicity and durability are found to be unsatisfactory in practice

Embodiment 1

[0015] Allyl polyether uses the azeotrope of toluene and water to remove moisture and the silicone oil is dried with anhydrous magnesium sulfate, then add 720 grams of allyl polyether as the reaction raw material in a 2L reactor, with a hydrogen content of 0.10%-0.20% 33.6 grams of hydrogen-containing silicone oil, 264 grams of solvent toluene, and 150 ppm of isopropanol solution of chloroplatinic acid as a catalyst were heated to 120° C. under a nitrogen atmosphere, stirred evenly, and kept for 4 hours for reaction. Toluene and low boilers were distilled off at a vacuum of 0.09 Ma to obtain a transparent viscous liquid which was polyether modified silicone oil.

[0016] Add 144 grams of dimethyl terephthalate into a 2L reaction kettle, raise the temperature to 150°C, and after the dimethyl phthalate is completely dissolved, add 320 grams of ethylene glycol, and add a transesterification catalyst of manganese acetate and di 1 gram of compound of antimony is heated up to 190 DE...

Abstract

The invention relates to a method for preparing a polyester and polyether modified silicone oil ternary copolymer textile finishing agent, and belongs to the field of the synthesis of ternary copolymer synthetic fiber finishing agents. The method comprises the following steps of: performing a hydrosilylation reaction of allyl polyether and hydrogen-containing silicone oil under the action of a chloroplatinic acid catalyst to form polyether modified silicone oil; and performing a polycondensation reaction of the polyether modified silicone oil and dimethyl terephthalate, glycol and polyethylene glycol under the action of antimonous oxide, manganese acetate, n-tetrabutyl titanate and triphenyl phosphate to obtain the polyester and polyether modified silicone oil ternary copolymer multifunctional textile finishing agent. The textile finishing agent can make textiles very absorbent, antistatic and washable and touch very soft.

Description

technical field [0001] The invention relates to a preparation method of a terpolymerized synthetic fiber finishing agent, in particular to a polyester and polyether modified organic silicone oil terpolymerized fabric finishing agent. Background technique [0002] Polyester fiber has excellent properties that many natural fibers cannot match, and is currently the most widely used type of synthetic fiber. However, the shortcomings of poor hygroscopicity, easy to be charged with static electricity, easy to absorb dirt, and poor hand feel limit the use of polyester fibers. In the development process of polyester fiber, people use fiber synthesis technology to modify polyester fiber and use fabric finishing technology to finish polyester fiber fabric, which improves the performance of polyester fiber. The commonly used polyester-polyether multi-block binary copolymer is used in the post-finishing method of fabrics, which makes the fabrics have good hydrophilic and antistatic pro...
