Description
Technical field
The present invention relates to a kind of synthetic fiber finish, particularly a kind of finish of use for spinning in urethane elastic fiber.
Background technology
Elastomer, it is polyurethane fiber, be referred to as spandex in China, because it has excellent elasticity, good dyeability, and characteristics such as density is little, brute force is high, percentage elongation is big, resilience is good, fast light, wear-resisting and corrosion-resistant are widely used in swimsuit, high-grade knitted underwear and garment material etc., and its development is very rapid.Since building the industrialized unit of 300 tons/year in first cover for Yantai from nineteen ninety, domestic spandex annual production has reached 100,000 tons, used finish reaches more than 6000 tons, spandex fiber technology mainly contains that dry method is spun, molten spinning, wet method is spun and react and spin etc., finish is given fiber surface by oil tanker or oil nozzle, makes fiber have good flatness, antistatic behaviour, convergence and unwinding.Fiberizing after the finish of function admirable makes and oils is good, adhesion between silk and the silk, and easy unwinding in the process of back, the limit of not collapsing, fracture of wire are few.
Present spandex production finish, mainly by Japanese this grease of bamboo company, pine this grease company and some grease companies of the U.S. provide, and existing questions is that the antistatic property of finish is poor, the unwinding of spandex silk in the process of back is relatively poor, and limit, fracture of wire easily collapse.As finish as described in the patent US4999120 mainly by dimethicone, compositions such as polyoxyethylene fatty alcohol, this finish oils with the emulsion state, is mainly used in wet method and spins urethane elastic fiber production technology, the dry method that does not fit into maximum is spun and the molten spinning production technology; Patent US3717575, the described spandex oil agent of patent J5-117976, J3-51374 all is made up of mineral oil, silicone oil and amino-modified silicone oil, and the characteristics of this type of finish are that the spandex silk that is spun is smooth, good hand touch, but antistatic property is poor.Finish of the present invention is by using polyoxyethylene modified silicon oil, polyethers and soap etc., solved the existing problem of existing finish, obtained successful commercial Application, the whole serviceability of finish has reached the requirement of spandex fiber technology and after-processing technology fully.
Summary of the invention
The present invention be directed to existing finish and exist antistatic property poor, the unwinding of spandex silk in the process of back is relatively poor, the problems such as limit, fracture of wire of easily collapsing, and provide a kind of new oil solution for spandex spinning, except using mineral oil, silicone oil, also used polyethers, polyether modified silicon oil and soap etc. in this finish, thereby stable performance, easy to use, anti-adhesion performance, antistatic property and level and smooth excellent performance, and in the process of back, easily unwinding, limit, not fracture of wire do not collapse.
