Problems solved by technology

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 exists in the fabric. The residual amine solvents that cannot meet the requirements of the European Union do not meet the requirements of product processing and environmental protection and safety

Abstract

The invention relates to a method for producing waterproof moisture permeability fabric based on a water foaming system. The method comprises the following steps: (1), water proofing and calendaring treatments on fabric; (2), preparation of water base coat foaming coating adhesive; (3), preparation of water surface coat foaming coating adhesive; and (4), a dry-method coating process. According to the fabric and the method, an environment-friendly water coating agent and a specific foaming system are developed; a simple coat processing technology is adopted; the high-waterproof moisture permeability fabric in a micro-nano hole structure is produced; by adopting the waterproof moisture permeability fabric produced by the invention, the waterproof property can be equal to that of a 10000mm water column; and the moisture permeability amount can be up to 7000g / m 2*24h by adopting a reverse cup method and is near to 2500g / m 2*24h by adopting an upright cup method.

Description

technical field [0001] The invention relates to a dry coating process, in particular to a production method of a microporous waterproof and moisture-permeable coated fabric using a water-based foam system. Background technique [0002] The consumption of outdoor products in China started around 2000, and then ushered in explosive growth. According to statistics, in 2011, the total retail sales of China's outdoor products reached 10.76 billion yuan, of which clothing and apparel accounted for more than 50%, with a year-on-year increase of more than 50%. The growth of outdoor products at home and abroad has promoted the rapid growth of the consumption of waterproof and moisture-permeable fabrics, and also put forward new requirements for waterproof and moisture-permeable fabrics. However, our country is facing the embarrassing situation of being only the world's processing plant and global product consumers. The real reason is that our country has not really mastered the core...
