Embodiment 1

[0033] Add 2 parts of sodium lignosulfonate, 0.1% AMP95, 4 parts of ethylene glycol, 0.3 parts of polysiloxane, 0.1 part of 1,2-benzisothiazolin-3-one in water, at 40°C at 1000rpm Premix for 5min. Then add 30 parts of cooling powder mixture (mica powder: boron nitride = 1:1), and continue stirring at 1500 rpm for 30 minutes. Put the pre-mixed materials into the sand mill, use 0.8-1.0mm zirconium beads for coarse grinding for 30 minutes, and 0.4-0.6mm zirconium beads for fine grinding for 15 minutes. The particle size of the cool-feel powder mixture in the cool-feel masterbatch was tested by a Malvern laser particle size analyzer, and the average particle size was 0.88 μm. After vacuum defoaming under negative pressure for 2 hours, the finished liquid color masterbatch was obtained.

Abstract

According to the invention, the particle size of the originally coarse cool powder is greatly reduced through a grinding process, and the finely ground nano-particles are stably dispersed in the liquid by using the coating agent, so that the powder is not easy to agglomerate and settle after being finely ground. Under the condition that the amount of the powder added into the fiber is certain, the finer the powder is, the better the dispersion is, the better the spinnability is, and the cool feeling performance of the fiber is improved. The pH is adjusted to be alkalescent, and the spinnability and the physical performance of the fiber can be improved to different degrees through mechanical defoaming. The liquid master batch for the cool-feeling viscose fiber prepared by the invention can be added into a viscose spinning solution to directly spin the cool-feeling viscose fiber, and has the advantages of good spinnability, washing resistance, less pollution, good fiber cool-feeling degree, lasting cool-feeling performance and the like.

Description

technical field [0001] The invention belongs to the technical field of functional liquid masterbatch, and in particular relates to a method for preparing a liquid masterbatch for cool-feeling viscose fiber. Background technique [0002] Most of the research on cool feeling fibers is mainly concentrated in chemical fibers produced by melt spinning, such as polyester, nylon, polypropylene and so on. However, these fibers themselves have some problems such as not being skin-friendly and airtight, and are often difficult to apply in some personal textiles. [0003] Viscose fiber is a cellulose fiber obtained by extracting and remodeling fiber molecules from natural wood cellulose using "wood" as a raw material. The hygroscopicity of viscose fiber meets the physiological requirements of human skin. It has the characteristics of smooth and cool, breathable, antistatic, anti-ultraviolet, colorful and good color fastness. It has the essence of cotton and the quality of silk. It is...
