Embodiment 1

[0034] Embodiment 1: a kind of environment-friendly size, including raw corn starch and size auxiliary agent, wherein size auxiliary agent is made up of starch viscosity reducer, plasticizer, wetting and penetrating agent, softening and smoothing agent and defoamer,

[0035] The slurry additive is made from the following raw materials by mass percentage:

[0036]

[0037]The steps for preparing the slurry additive are as follows: install the condenser tube, the stirrer and the three-necked flask; Put the starch viscosity reducer, wetting and penetrating agent, and smoothing agent into a three-necked flask, set the temperature at 55°C, stir for 30 minutes, and pour it into a beaker; place the beaker in a high-speed emulsifier, set the speed at 5000r / min, and the emulsification time After 30 minutes, add a specified amount of plasticizer and defoamer compound to emulsify at a low speed for 20 minutes to obtain a translucent white emulsion, take it out, adjust the pH value to ...

Embodiment 2

[0042] Embodiment 2: A new type of environment-friendly size aid is composed of two parts, including corn starch and size aid, wherein the size aid is composed of starch viscosity reducer, plasticizer, wetting and penetrating agent, softening and smoothing agent and defoamer composition.

[0043] The slurry additive is made from the following raw materials by mass percentage

Abstract

The invention relates to the field of textile, and in particular to slurry, which comprises two parts, i.e. main slurry and an additive, wherein the main slurry is refined corn starch, a variety of materials are compounded to form the additive, and the proportion of each material component is as follow: 1 to 1.5% of astarch reducing viscosity agent, 3 to 5% of a softening agent, 10 to 12% of a plasticizer, 12 to 15% of a wetting agent, 0.9 to 1.5% of a defoaming agent, the balance of deionized water. After the slurry is used for sizing Lyocell fibers, problems caused in the process of sizing,such as secondary hairiness, surface roughness and nonuniform strength, are solved, and ultimately, the efficiency of weaving is increased.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a sizing material, a sizing method and a sizing process thereof. Background technique [0002] Starch is a degradable polysaccharide natural polymer compound with rich sources, which has the advantages of low price, renewable, easy to degrade, and less environmental pollution. The starch size prepared from it is suitable for cellulose fiber yarn of sizing. However, the starch macromolecular chain is composed of cyclic glucose residues. The cyclic structure and polarity make it poor in flexibility, high in glass transition temperature, and hard and brittle. Therefore, when starch size is selected as the main size, it is usually necessary to add certain special additives to improve the sizing performance so that it meets the weaving requirements. [0003] There is seldom mention of the technology of whole starch sizing lyocell fiber in existing literature, mostly is the research of modifi...
