The invention discloses an environment-friendly textile size and a preparation method thereof, which is composed of the following raw materials in parts by mass: 30-40 parts of modified starch, 0.4-0.6 parts of potassium pyrophosphate, 2-8 parts of polyethylene terephthalate Alcohol ester, 4-12 parts of polyacrylic acid slurry, 0.8-2.2 parts of urea, 6-10 parts of calcium chloride, 2-4 parts of bentonite, 1-3 parts of sodium lignosulfonate, 1-3 parts of defoamer And 28-50 parts of deionized water, through heating up, primary mixing, secondary mixing, three mixing, stirring and cooling encapsulation steps, complete the preparation of environment-friendly textile size; the present invention replaces conventional PVA by adopting polyacrylic acid type size Size, non-toxic and harmless, easy to biodegrade, easy to desizing, eco-friendly textile size, used in conjunction with modified starch size has a strong effect on cotton, polyester cotton, hemp, rayon, tencel and other fibers Adhesiveness, abrasion resistance. Good size stability and permeability, no pulp spots, dry splitting and splitting lightly, reduce secondary hairiness, and increase good axis ratio of sizing. |
