Description
Technical Field
The invention relates to the technical field of textile materials, in particular to a high-comfort waterproof breathable yarn-card composite fabric and a production method thereof.
Background
The yarn card belongs to its fabric of card, and the warp and weft yarn of yarn card all is single yarn, and the twill direction is left skew, and its front has clear twill line, and reverse side twill line is not obvious, generally calls single face yarn card. The yarn card cloth is generally elaborately made of high-quality cotton and polyester materials and has the characteristics of being light, thin, soft, smooth, breathable and the like. The red yarn card cloth has wide applicability, is commonly used for various clothes, shoes, stage decoration and the like, can also be used as leather auxiliary materials, and is one of indispensable materials in the cloth.
The yarn card fabric is used as a garment fabric, is the most common fabric for custom-made work clothes, and has a plurality of types and different characteristics. The work clothes made of the yarn card fabric are mostly applied to industries such as factory workshops, technical workers, electric power engineering, building engineering, logistics maintenance and the like, mainly because the work clothes made of the yarn card fabric have the advantages of dirt resistance, wear resistance, difficulty in wrinkling and the like. Besides being a good choice of the frock fabric, the yarn card fabric can also be a material commonly used by casual pants. The all-cotton yarn card product has the characteristics of uniform, smooth and clean cloth cover, simplicity, softness, stable shaping, moisture absorption, wear resistance and the like, is mostly selected for casual pants, and particularly has the more prominent characteristics of softness, comfort and no crease after ironing-free treatment, thereby becoming the preferred fabric for casual long and short pants at present. However, most yarn card fabrics in the market generally have poor air permeability and sweat releasing performance, poor moisture absorption and low wearing comfort after long-time wearing and working.
