Problems solved by technology

The known method for obtaining waterproof fabrics is to apply a layer of impermeable coating on the surface of common fabrics, such as polyvinyl chloride resin, polyurethane resin, etc., to eliminate the water permeability of fabrics. This type of method used more in the past. Many, but it is not the best way to solve the problem, because this coating can not pass through water vapor, it limits the distribution of human sweat after evaporation, and makes water vapor condense on the inner surface of the fabric, which is very uncomfortable to wear

Embodiment Construction

[0011] The embodiment discloses a production method of a waterproof and moisture-permeable fabric, comprising the following steps:

[0012] 1), carry out anti-splashing treatment to the fabric (this step belongs to the known technology): even if the fabric passes through the immersion tank (the immersion tank is equipped with liquid Teflon water repellent), then dry and bake the soaked fabric Drying treatment, the drying temperature is controlled at 100-105°C; the drying temperature is controlled at 170-175°C; the time is 1.5 minutes, and the fabric after the water-repellent treatment has the functions of waterproof, oil-proof and anti-fouling;

[0013] 2) Carry out calendering treatment on the baked fabric, the fabric passes through the pressure roller of the calender at a speed of 25-27m / min, the surface of the fabric after the calendering treatment is smooth, thereby improving the water pressure resistance of the coating And it is not easy to see through, and at the same ti...

Abstract

The invention discloses a method for producing a waterproof moisture permeable fabric with functions of moisture permeating and water proofing, which comprises the following steps: firstly, soaking a fabric into a soaking groove filled with Teflon waterproof agent for 1 to 2 minutes, and then drying and baking the soaked fabric; next, calendering the fabric, and then coating bottom adhesive on the calendered fabric surface; and finally, coating surface adhesive on the surface of the surface of the fabric bottom adhesive, wherein the bottom adhesive consists of 100 portions of polyfluortetraethylene, 10 to 15 portions of toluene, 10 portions of polyacrylate, 3 to 5 portions of cross-linking agent, and 1 to 2 portions of accelerating agent in portion by weight; and the surface adhesive consists of 100 portions of polyfluortetraethylene, 10 to 15 portions of toluene, 10 portions of polyacrylate, and 2 portions of smooth anti-sticking agent in portion by weight.

Description

technical field [0001] The invention relates to a fabric treatment process, in particular to a production method of a waterproof and moisture-permeable fabric. The prepared fabric is suitable for occasions requiring waterproof functions such as medical clothing, military clothing, and field work clothing. Background technique [0002] Waterproof and moisture-permeable fabric (also known as fabric) means that water will not soak into the inner side of the fabric under a certain pressure, but the sweat emitted by the human body can be transmitted to the outside through the fabric in the form of water vapor, thereby preventing sweat from accumulating and condensing on the body surface and the fabric. In order to maintain the comfort of wearing, it is a high-tech, unique functional fabric. When it is used in medical clothing, it can effectively prevent the patient's blood and body fluids from infecting medical staff; when it is used in military clothing, it requires light weight...
