Embodiment 1

[0020] A kind of nylon film, its processing method:

[0021] Add 100 grams of modified nylon resin, 20 grams of silicon compound with an average particle size of 15 μm, and 400 grams of solvent into an empty container, stir at high speed (500-1500 rpm), and then add 5 grams of additives and stir evenly.

[0022] Apply the adjusted solution evenly on the surface of the release paper using a coating machine to control the range of thickness variation. After drying at 50°C for 2 minutes and 120°C for 2 minutes, the film is formed, and the film is peeled off with a special peeling machine. Peel it off to test its performance.

[0023] In the above steps, use a coating machine to evenly coat the solution on the surface of the release paper, and control the range of thickness variation to obtain films with different thicknesses. For example, the average thicknesses of films with different thicknesses are 18.0 μm, 29.6 μm, 38.0 μm. The elongation of the film is between 50% and 400%...

Embodiment 2

[0035] A waterproof and moisture-permeable fabric laminated with nylon membrane

[0036] The nylon film with a thickness of 18.0 μm and the ordinary nylon woven fabric are passed through the dotted rolls of the laminating machine, and the adhesive is evenly transferred to the produced film, and then the nylon cloth and the nylon film are bonded together by the rolls. The measured properties are shown in the table below:

Abstract

The invention discloses a nylon membrane and waterproof and moisture permeable cloth attached by the same, wherein the nylon membrane takes modified nylon as a main component. At present, the nylon membrane and the waterproof and moisture permeable cloth attached by the same have the characteristics of recoverability, environmental protection, waterproofness, moisture permeation and the like, and have high practicability under the condition of continuously increased environmental protection requirement.

Description

Technical field: [0001] The invention relates to a nylon film and a waterproof and moisture-permeable fabric bonded thereto. Background technique: [0002] There are various kinds of waterproof and moisture-permeable textiles, including high-density textiles, coated textiles, and laminated textiles. Among them, the laminated and processed textiles are relatively good at solving the contradiction of waterproof and moisture permeability, and have good waterproof performance, and the moisture permeability is also greatly improved compared with coated fabrics. The film plays a dominant role in laminated products, and the results of waterproof and moisture-permeable films emerge in an endless stream, including acrylic resins, polyurethanes, polyvinyl chloride, rubber-based resins, and polytetrafluoroethylene. With the advancement of science and technology, the waterproof and moisture-permeable properties of various membranes have made great progress. Polyurethane resin has a la...
