Problems solved by technology

For example, Chinese patent CN00216185.0 discloses a waterproof, windproof, breathable, and moisture-permeable chemical fiber fabric composite fabric, which uses chemical fiber fabric as the outer layer, windproof, waterproof, and moisture-permeable film as the middle layer, and chemical fiber fabric as the inner layer. Integral to achieve the characteristics of waterproof, windproof and breathable, because such composite fabrics are not elastic, it is difficult to meet everyone's needs for wearing comfort and freedom of movement; at the same time, because the chemical fiber fabrics are used, they lack the texture and touch of natural fibers
Another example is Chinese patent CN00216183.4 which discloses a waterproof, windproof, and moisture-permeable wool fabric composite material, which uses wool fabric as the outer layer, breathable, moisture-permeable, windproof, and waterproof film as the middle layer, and natural fiber fabric as the inner layer, and the three layers are connected into one , to meet the functional requirements of moisture permeability, moisture absorption, windproof, waterproof and heat preservation during wearing, and solve the defect of chemical fiber touch on the surface of composite materials, but there are still problems of insufficient elasticity and inconvenient movement
Another example is that Chinese patent CN201210068578.1 discloses a multi-layer windproof fabric and its application. The surface adopts cotton-containing woven fabric, the middle layer adopts non-porous polyurethane film, and the lining layer is pure polyester raised knitted fabric. It achieves the function of windproof and warm keeping in one piece, but also has the problems of insufficient elasticity and inconvenient movement

Abstract

The invention discloses a multilayer elastic windproof fabric and a production method thereof. The fabric has a three-layer structure, the surface layer is a woven fabric formed of cotton / spandex or polyester / cotton / spandex; the middle layer is a polyurethane resin film; the inner layer is a knitted fabric formed of 100% polyester or acrylic fiber / viscose; the surface layer and the middle layer , The lamination of the middle layer and the inner layer is discontinuous lamination. The windproof fabric of the present invention has superior elasticity, plump and soft hand feeling, high peelability, and superior moisture permeability, water pressure resistance, windproof and thermal performance, and is suitable for making elastic trousers worn in winter.

Description

technical field [0001] The invention relates to a multilayer elastic windproof fabric and a production method thereof, in particular to a multilayer elastic windproof fabric especially suitable for making winter trousers and a production method thereof. Background technique [0002] With the improvement of living standards, when people choose winter clothes, they not only pursue the basic wearability of covering the body and keeping warm, but also put forward new requirements for wearing comfort, functionality and aesthetics. In the cold winter, especially in outdoor environments without air conditioning, ordinary trousers are difficult to resist the invasion of cold currents, strong winds, and invasion of rain and snow. Down trousers, quilted trousers and other trouser designs came into being. The warm and windproof performance meets people's needs to a certain extent, but at the same time, it is also relatively bulky, unattractive, inconvenient to move, and feels stuffy to...
