Abstract

The invention discloses a preparation method of a clean type pure cotton yarn sizing agent. The preparation method comprises the following steps: firstly, preparing a glutin dissolved liquid and a monomer pre-emulsion; then, under the effect of an initiator, carrying out reaction with an acrylic acid monomer to prepare a protein derivative assistant; and finally, preparing a positive ion crosslinking modifier WLS and carrying out reaction with the protein derivative assistant to obtain the clean type pure cotton yarn sizing agent. The invention relates to the preparation method of the clean type pure cotton yarn sizing agent. The sizing agent not only has the characteristics of improving the strength of the yarn, reducing yarn hairiness, improving the abrasive resistance of the yarn, having good compatibility with other slurry, replacing PVA (Polyvinyl Acetate) slurry and effectively reducing the breakage of the cotton yarn during weaving and the like, but also the dyeing performance of the sizing fabric is improved by means of the structural characteristic of the slurry, so that the use level of salt for dyeing is reduced and the use level of dyes is saved, and slurry on the fabric is not completely removed, so that the environmental pollution is effectively alleviated and the waste protein resources are effectively used.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a preparation method of a clean pure cotton yarn sizing agent. Background technique [0002] The size currently used in my country is generally three types: modified starch, polyvinyl alcohol (PVA) and acrylic size. Starch has a long history as the main size of warp yarn in my country. Starch has good adhesion to hydrophilic natural fibers, and also has a certain film-forming ability. It is easy to degrade, but its viscosity fluctuates greatly and its gelatinization performance is poor. , need to add a large amount of auxiliary additives. Acrylic size has excellent adhesion to all kinds of fibers, good water solubility, and is easy to desizing, but its biggest disadvantage is that it has serious moisture absorption and re-viscosity, and the price is high, so it is only used as an auxiliary size in China at present. PVA is a typical water-soluble polymer c...
