Abstract

The invention relates to a production process of a hollow fiber raschel blanket, comprising the following steps: 1) yarn selection, 2) weaving, 3) scouring, 4) printing and dyeing, 5) reduction cleaning, and 6) finishing. The invention adopts the hollow thermal fiber as the plush yarn of the Raschel blanket, and utilizes the characteristics of the porous surface of the fiber. The product of the present invention adopts the hollow thermal insulation fiber on the basis of maintaining the characteristics of similar products such as natural luster, good air permeability, and improved skin-friendliness. As the plush yarn raw material of the Raschel blanket, the cross-sectional structure reduces the weight of the fiber by 20%, and the fiber contains a large amount of still air, which improves the warmth retention of the product by 65% ​​compared with ordinary homogeneous fabrics.

Description

technical field [0001] The invention relates to the technical field of production of functional raschel blankets, in particular to a production process of hollow fiber raschel blankets with environmental protection, lighter products, more warmth and ventilation. Background technique [0002] Looking at the development trend of textiles at home and abroad, functional high-tech textiles have become the mainstream of market development. People not only require aesthetics of textiles, but also focus on comfort and functionality. Therefore, functional textiles have become one of the future development trends of the textile industry, and together with fine denier fiber textiles, non-woven fabrics, composite materials, and environmentally friendly materials, they will constitute the major trend of future textiles. [0003] The hollow thermal fiber is used as the plush yarn of the Raschel blanket, and the porous surface of the fiber is used to make the fiber rich in non-convective ...
