Abstract

The invention discloses a cotton fabric non-iron finishing solution compounded with water-based polyurethane, a preparation method and application thereof. The cotton fabric non-ironing finishing solution includes etherified 2D resin, water-based polyurethane, catalyst, penetrating agent, softener, Strong protective agent and solvent; based on the solvent, the mass fraction of each component is: etherified 2D resin 8-10%, water-based polyurethane 3-6%, catalyst 1-3%, penetrant 0.1-0.2%, softener 2-4%, strong protective agent 2-4%; wherein, the solvent is water. The present invention selects water-based polyurethane and etherified 2D resin for compounding, exerts the synergistic effect of the two on non-ironing finishing, reduces the amount of resin under the premise of ensuring the finishing effect, and effectively improves the strength retention rate of the fabric after finishing.

Description

Technical field [0001] The present invention belongs to the field of textile finishing technology, specifically relates to a kind of cotton fabric non-iron finishing fluid compounded with waterborne polyurethane, preparation method and application thereof. Background [0002] Cotton fiber materials have attracted attention among many fiber materials because of their excellent characteristics such as softness and comfort, good moisture absorption and breathability, good dyeing effect, and antistatic. The cotton cellulose macromolecule is composed of β-D glucose residue groups through 1,4-glycoside bonds, of which each glucose ring retains 3 free hydroxyl groups that can form hydrogen bonds, therefore, the cellulose fiber material has excellent characteristics such as moisture absorption, breathability and softness, but at the same time, the structure also determines its inherent defects such as poor elasticity, easy to wrinkle, ironing after washing, etc., affecting its performanc...
