Dry-process spandex spinning oil agent

Abstract

The invention discloses a dry-process spandex spinning oil agent. The dry-process spandex spinning oil agent comprises the following components in percentage by weight: 20%-80% of dimethyl silicone oil, 5%-45% of mineral oil, 1%-10% of organic silicon quaternary ammonium salt, 0.5%-10% of an antistatic agent, 0.1%-10% of stearate and 1%-10% of a functional component. The functional component is natural extract of one or more of folium artemisiae argyi, mint, mozzie buster, lavender, pelargonium hortorum, cordate telosma and murraya paniculata, and also can be natural essence oil of roses, jasmines, citrus bergamia, sandalwood and the like.

Description

technical field [0001] The invention relates to a spinning finish, in particular to a spandex dry spinning finish. The spandex dry spinning oil agent of the invention not only makes the spandex fiber treated by it have good unwinding and antistatic properties, but also has one or more functions such as antibacterial, mosquito repellent and fragrance. Background technique [0002] Polyurethane elastic fiber (referred to as "spandex") is an indispensable "MSG-like" textile raw material in the modern textile and garment industry. It can be used in all fabrics that require good elastic recovery rate, so it is widely used in various underwear, sportswear, Clothes, swimwear, high elastic socks, tights, diapers and other fields. With the improvement of living standards, people are no longer simply satisfied with the basic functions of their fabrics, but more and more pursue the fashion and functionality of their fabrics, so fibers with special functions are becoming more and more ...

Problems solved by technology

[0004] Recently, differentiated spandex products have developed rapidly. Among them, patent CN103924320A introduces a preparation method of insect-repellent spandex fiber, which is based on adding insect repellent to the spinning stock solution to obtain spandex by high-temperature dry spinning. The preparation of insect-repellent fiber by this method is complicated. The selected mosquito repellent will make the human body uncomfortable, and it is not conducive to the maintenance of the equipment; the spandex oil described in the existing spandex oil patents CN102877296A and CN101597864A can endow the fiber with conventional properties such as antistatic, softness and unwinding property, But it has no other functions. The spandex oil agent described in patent CN104005235A can endow fibers with functions such as antistatic, antibacterial, moisture absorption, and decontamination, but it is mainly used in spandex coarse denier yarn
