Abstract

The invention discloses spinning oil for a fine-denier melt-spun spandex fiber. The oil comprises the following components by weight percentage: 30-60% of dimethyl silicon oil, 30-50% of modified silicone oil, 0-10% of nonionic surfactant and the balance of other additive, wherein the modified silicone oil is amino modified silicone oil or polyether modified silicone oil; polysiloxane chain segments m and n in the amino modified silicone oil are equal to 30-120; an adduct number b of polyoxyethylene chain segments in the polyether modified silicone oil is equal to 0-10; an adduct number a of polyoxypropylene chain segments is equal to 0-10; the nonionic surfactant is fatty alcohol polyoxyethylene ether, fatty alcohol polypropylene oxide ether or fatty alcohol polyoxyethylene polyoxypropylene ether; and other additive is phosphate potassium salt of alkyl alcohol polyoxyethylene ether.

Description

technical field [0001] The invention relates to a textile auxiliary agent, in particular to a fine-denier melt-spun spandex fiber spinning oil. Background technique [0002] Spandex fiber is the abbreviation of polyurethane fiber. It is a block copolymer obtained by polymerization of diol and diisocyanate, and then synthesized by dry method, wet method or melt spinning. fiber. Spandex has the characteristics of high elongation and high elasticity, and is a kind of high elastic fiber. It is often made into core-spun yarn with other fibers, and used to make elastic parts of various underwear, swimwear, tights, jeans, sportswear, etc. Although the amount of spandex used in the fabric is small, it can change the stretching effect of the fabric, improve the wearing performance of the product, improve the sense of oppression and freedom of movement of the relevant parts of the human body, and have perfect comfort and good fit. As a result, the grade of the product is greatly im...
