Abstract

The invention relates to a composition for improving the hydrostatic pressure resistance of a fluorine-series waterproof agent and a use method of the composition. The composition comprises a fabric modification stiffening agent and a polymer wax emulsion. The method comprises the following steps of mixing the fluorine-series waterproof agent, the composition and water, carrying out padding treatment on a fabric by using obtained waterproof finishing liquid, and then performing baking. The composition can obviously improve the improvement effect of the waterproof agent on the hydrostatic pressure resistance of the fabric without reducing the properties such as the air permeability and color of the fabric, and can reduce the dosage of the waterproof agent and greatly save the production cost.

Description

technical field [0001] The invention belongs to the field of functional finishing agents for textiles, in particular to a composition for improving the hydrostatic pressure resistance of fluorine-based waterproofing agents and a method for using the same. Background technique [0002] Hydrostatic pressure refers to the resistance encountered by water passing through the fabric. Hydrostatic pressure resistance is an important indicator of waterproof and moisture-permeable fabrics (such as jackets, tents, umbrellas, medical protective clothing, etc.), and the higher the hydrostatic pressure evaluation level of the fabric , the better the water resistance and leakage resistance. At present, most of the fabrics on the market use the coating method or the composite finishing method of coating and waterproofing agent to improve the effect of hydrostatic pressure resistance. For example, Chinese patent CN201320044240.2 discloses a fabric for public security uniforms. Polyurethane ...
