Breathable cloth and production technology of cloth

Abstract

The invention discloses breathable cloth and a production technology of the cloth. The breathable cloth comprises polyester taffeta ripstop base cloth. The production technology comprises the following production steps: step 1, immersing the base cloth into a waterproof agent solution to perform waterproof treatment; step 2, rolling the waterproof treated base cloth and drying the base cloth, wherein a drying temperature is 60 to 170 DEG C; step 3, evenly sizing one side of two sides of the base cloth at least once, drying after each time of coating and finally drying to obtain the breathablecloth. According to the breathable cloth disclosed by the invention, appropriate amount of PU resin coating layers are coated to one side or two sides of the breathable cloth; under the appropriate pressure, warps and wefts of the cloth can open appropriate gaps under the control of a coating adhesive to achieve the purpose of accurately and constantly controlling breathability. According to the breathable cloth disclosed by the invention, the breathable cloth can maintain air pressure as a 100 to 2000mm mercury column in testing or forming a sealed inflation bag through the coating amounts ofthe coating layers when a testing constant inflation volume is not smaller than 500m<3> / min, and the breathability can be completely, constantly and accurately controlled in a certain range.

Description

technical field [0001] The invention relates to a breathable cloth, a manufacturing process and application of the cloth. Background technique [0002] The air-permeable cloth used in special circumstances requires the cloth to form a closed environment, while being breathable, it is also required to maintain a certain air pressure so as to be used as a support. Most of the existing air-permeable fabrics need to manufacture the vent holes as evenly and densely as possible, so that the gas can overflow from the vent holes to the greatest extent. Dense exhaust holes need to be punched through the subsequent punching process. Considering the strength of the fabric, the punching holes should not be too dense, so that it is difficult to control the exhaust evenly. The strength of the punched fabric will be affected to a certain extent. All in all, the existing air-permeable cloth has a complicated production process, and its air-permeable uniformity and strength are not good. ...
