Abstract

The invention discloses novel soft and smooth silicone oil for polyester and a preparation method of the novel soft and smooth silicone oil. The novel soft and smooth silicone oil comprises the following raw materials in parts by mass: 2-10 parts of polyether amine, 1-5 parts of diethyl terephthalate, 10-30 parts of epoxy-terminated silicone oil, 10-30 parts of an organic solvent, 0.1-0.3 part of organic acid and 30-50 parts of deionized water. According to the novel soft and smooth silicone oil for terylene adopting the structure and the preparation method of the novel soft and smooth silicone oil, special polyether amine is prepared through amidation of diethyl terephthalate and polyether amine, epoxy-terminated polyether siloxane with medium and small molecular weight and the special polyether amine are subjected to polycondensation, and the prepared soft and smooth silicone oil for terylene can endow various terylene fabrics with softness, elasticity and elasticity. The handfeel is soft, smooth and fine.

Description

technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a novel soft and smooth silicone oil for polyester and a preparation method thereof. Background technique [0002] Polyester fabric is a kind of chemical fiber clothing fabric widely used in daily life. It has the advantages of good elasticity, good heat resistance, good wear resistance, good light resistance, corrosion resistance, and high strength of polyester fabric. However, the disadvantages of polyester fabrics are also obvious. It is uncomfortable to wear, and the hard fibers will rub against the skin. In recent years, more and more polyester velvet fabrics are used in daily life, such as chiffon fabrics for summer women's clothing, which require a soft and silky feel; or fabrics such as polyester coral fleece, polyester flannel, polyester super soft, etc. , is used to make winter pajamas, winter bedding, etc. The more close-fitting the material is, ...
