Problems solved by technology

Later oils gradually began to add silicone oil and modified silicone oil as anti-adhesion components. Silicone oil and modified silicone oil have good anti-sticking properties, but after using silicone oil and modified silicone oil, the fabric will be difficult to clean and difficult to dye.
Usually, stearate is added to the spandex oil system. Stearate can make the spandex fiber have better unwinding performance, but the dispersibility of stearate in spandex oil is not very good.
Therefore, it is very necessary to develop a silicone-free oil composition for spandex dry spinning through formula adjustment, which not only overcomes the adverse effects of silicone oil in spandex oil, but also solves the problem of poor dispersibility of stearate. question

Embodiment approach

[0076] In a preferred embodiment, the nano-mesoporous silica includes one or a combination of MCM-41, MCM-48, MCM-50, SBA-15, and SBA-16.

[0077] The synthesis mechanism of the "nano mesoporous silica" is: use the structure composed of many kinds of surfactants as a template to form an ordered mesoporous material, through various physical and chemical processes (for example: microemulsion, emulsification or Sol-gel), will directly act on the surface of organic and inorganic substances, wrap the inorganic ion polymer into an orderly assembly, and finally undergo calcination and other treatments to completely remove the organic substances, retain the original framework structure, and finally form Porous ordered mesoporous materials.

[0078] In the present invention, the "mesoporous silica" can be synthesized by hydrothermal synthesis method, room temperature synthesis method, phase transformation method, microwave synthesis method, precipitation method, sol-gel method, etc. Of...

Embodiment approach 1

[0087] Embodiment 1: Embodiment 1 of the present invention provides a silicone-free oil composition for dry spinning of spandex, comprising at least the following components:

[0088]

[0089]

Embodiment approach 2

[0090] Embodiment 2: Same as Embodiment 1, the difference is that the non-silicon oil agent composition for spandex dry spinning is characterized in that it includes at least the following components:

Abstract

The invention belongs to the technical field of dry spinning oil and particularly discloses a silicone-oil-free agent composition for spandex dry spinning. The silicone-oil-free agent composition is at least prepared from a hydrocarbon compound, isoalcohols or acid, higher fatty acid salt, an antistatic agent and a dispersing agent. The silicone-oil-free agent composition for spandex dry spinning has the advantages that the composition is clear and transparent liquid and has good anti-sticking isolation and unwinding performance, and oiled spandex filaments can be attached and compounded and adhere to one another, dyeing is easy and uniform, and the anti-static performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of dry spinning oil, and more specifically relates to a silicone-free oil composition for spandex dry spinning, and also relates to a preparation method of the silicone-free oil composition for spandex dry spinning. 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 popular. [0003] By the end of 2015, the total production capacity o...
