Problems solved by technology

[0003] However, after the spandex fibers are oiled with domestic oil agents, on the one hand, the isolation between fibers is not good. As time goes by, chemical reaction type adhesion occurs between fibers, which cannot be unbundled and used, wasting Large amount of spandex yarn
On the other hand, the friction between fibers is too small, resulting in loose spinning and difficult molding
In light cases, "orbital threads" and "convex threads" appear, and in severe cases, random threads appear and cannot be spun. In view of the problems existing in the oils on the market, this invention provides an auxiliary product for compounding and producing spandex spinning oils

Abstract

The invention discloses an auxiliary product used in spandex spinning oil to isolate and adjust friction, and relates to the technical field of functional silicone materials. The structure of the auxiliary product is (A 3 SiO 0.5 )a(BMe 2 SiO 0.5 )b(CMe 2 SiO 0.5 )c(DMe 2 SiO 0.5 )d(Me 2 SiO)e(SiO 2 )f, wherein, A refers to a methyl and hydroxyl hybrid structure, B refers to a long-chain alkyl group, C refers to a glycidyl ether group, D refers to a polyether group, and Me refers to a methyl group. The auxiliary agent provided by the present invention introduces dimethylsiloxane chains, long-chain alkyl chains, epoxy hydrocarbon chains, polyether chains on the basis of the traditional MQ silicone resin structure and retains some active hydroxyl groups to make it Produces chemical bonding with spandex fiber, which not only provides long-lasting compatibility, storage stability, but also provides antistatic and proper unbundling tension.

Description

technical field [0001] The invention relates to the technical field of functional organosilicon materials, in particular to an auxiliary product which is used in a spandex spinning oil and plays the role of isolating and adjusting friction. Background technique [0002] In recent years, China's spandex spinning industry has become a major silk producing country in the world with its rapid development momentum. The matching high-end spandex spinning oil has always been dominated by Japanese "Matsumoto", "Takemoto" and American "Galston" oil. The main reason is that Japan and the United States are outstanding in terms of product quality, output and performance. [0003] After the domestic oiling agent is oiled on the spandex fiber, on the one hand, the isolation between the fibers is not good. As time goes by, chemical reaction-type adhesion occurs between the fibers, which cannot be unbundled and used, which is a waste of time. Lots of spandex yarn. On the other hand, the ...
