Problems solved by technology

However, the formula of the oil is relatively simple, and there are only smoothing agents, antistatic agents and emulsifying conventional functions in the formula, and the addition of mineral oil will cause the increase of volatile substances, which will have a great impact on the environment

Abstract

The present invention provides a chinlon spinning additive. The additive consists of the following components in parts by weight: 5 to 10 parts of zinc oxide, 3 to 5 parts of titanium dioxide, 2 to 6 parts of montmorillonite, 3 to 6 parts of vermiculite, and 1 to 3 parts of dispersing agent. The additive prepared in the present invention has a small grain size and good dispersing performance, and can improve the stability of spinning oil, ultraviolet prevention and antibacterial performance of the spinning oil after the additive is added into the spinning oil.

Description

technical field [0001] The invention relates to the technical field of auxiliary agents in synthetic fiber processing technology, in particular to an additive for nylon spinning. Background technique [0002] Nylon is the trade name of polycaprolactam fiber in my country, and the foreign trade name is nylon. In 1938, German Schlack successfully researched polycaprolactam made of single caprolactam as raw material and heated polymerization, and applied for a patent. As early as 1955, DuPont of the United States applied for a patent for spinning nylon at a speed of 5,500 m / min. Nylon fiber has excellent performance, except for the corrosion resistance and mildew resistance common to all synthetic fibers, high wet strength, not afraid of insects, and moisture absorption. In addition to its low rate, its main feature is its high breaking strength. Except for aramid, it is almost the strongest fiber; it has excellent wear resistance and is the fiber with the best wear resistance ...
