Abstract

The invention discloses a cotton fabric non-ironing finishing liquid compounded with waterborne polyurethane as well as a preparation method and application of the cotton fabric non-ironing finishing liquid. The cotton fabric non-ironing finishing liquid is prepared from etherified 2D resin, waterborne polyurethane, a catalyst, a penetrating agent, a softening agent, a strong protective agent and a solvent; and on the basis of the solvent, the cotton fabric non-ironing finishing liquid comprises the following components in percentage by mass of 8-10% of etherified 2D resin, 3-6% of waterborne polyurethane, 1-3% of the catalyst, 0.1-0.2% of the penetrating agent, 2-4% of the softening agent and 2-4% of the strong protective agent, wherein the solvent is water. The waterborne polyurethane and the etherified 2D resin are compounded, the non-ironing finishing synergistic effect of the waterborne polyurethane and the etherified 2D resin is exerted, on the premise that the finishing effect is ensured, the resin dosage is reduced, and the strength retention rate of the finished fabric is effectively increased.

Description

technical field [0001] The invention belongs to the technical field of textile post-finishing, and specifically relates to a cotton fabric non-ironing finishing liquid compounded with water-based polyurethane, a preparation method and an application thereof. Background technique [0002] Cotton fiber material has attracted much attention among many fiber materials because of its softness and comfort, good moisture absorption and air permeability, good dyeing effect, antistatic and other excellent properties. Cotton cellulose macromolecules are composed of β-D glucose residues linked by 1,4-glycoside bonds, and each glucose ring retains 3 free hydroxyl groups that can form hydrogen bonds. Therefore, the cellulose fiber material has It has excellent wearing properties such as moisture absorption, breathability and softness, but at the same time, this structure also determines its inherent defects such as poor elasticity, easy to wrinkle, and need to be ironed after washing, wh...
