Problems solved by technology

[0004] At present, a common problem in textiles is the contradiction between waterproof and moisture permeability. The hydrostatic pressure resistance and positive cup moisture permeability of waterproof and moisture-permeable fabrics are a pair of contradictions. Usually, the moisture permeability of fabrics with good hydrostatic pressure resistance is lower. Low, that is, the coating agent with high moisture permeability has poor waterproof ability; the coating agent with good waterproof ability has poor moisture permeability; Excellent waterproof and moisture permeability properties can be achieved at the same time

Abstract

The invention discloses a preparation method of water-based high-performance waterproof and moisture permeable coated fabric. The preparation method comprises the following steps: (1) preparing a prime coat adhesive; (2) preparing a topcoat adhesive; (3) preparing coated fabric. The preparation method is short in production technology process, simple in process, water-based and environment-friendly, and free from pollution, and saves cost and reduces the energy consumption, and a coated finish product has the advantages of excellent waterproof and moisture permeable performance, full hand feeling, high draping property and the like.

Description

technical field [0001] The invention belongs to the field of textile materials, and relates to a fabric preparation method, in particular to a water-based high-performance waterproof and moisture-permeable coated fabric preparation method. Background technique [0002] Waterproof and moisture-permeable fabrics have the functions of windproof, waterproof and moisture permeability, and are widely used in functional clothing, tents, shoes and industrial fields. At present, the main processing methods of waterproof and moisture-permeable fabrics on the market are the use of polytetrafluoroethylene (PTFE) microporous membranes and fabric lamination and wet coating. [0003] PTFE microporous membrane has the best waterproof and moisture permeability effect, but it is extremely difficult to prepare, expensive and cannot be produced locally; wet coating processing can also form a good microporous structure, but the processing process is extremely polluting, and there are amines in t...
