Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

With reference to fig. 1, the utility model discloses an air-jet vortex spun hollow yarn, which comprises a yarn body. The yarn body is cavity yarn line structure, is provided with the core hole in yarn body inside. The core pores are formed by hydrolysis of PVA fibers. The existing hollow yarn is mainly formed by directly spinning through friction spinning, the core yarn is made of PVA filaments, cotton fibers are wrapped and wound outside the hollow yarn, the overall uniformity of the yarn is poor, meanwhile, the PVA filaments are adopted for the core yarn, so that the yarn evenness of the core yarn is not uniform, and the moisture conductivity of a cotton fiber wrapping layer is poor. The utility model discloses a yarn body includes first cortex 1 and second cortex 2. The core hole is externally coated with a first skin layer 1. The utility model discloses use the PVA short fiber as the core yarn, spin the core yarn earlier through the vortex spinning technology, it is even to make the evenness, the less core yarn of surface hairiness to the core hole size after making the hydrolysis is even. And doubling the moisture-guiding filaments and the core yarns to uniformly distribute the moisture-guiding filaments around the core yarns, coating polyurethane breathable microporous adhesive on the surface of the first skin layer 1 in order to improve the distribution stability of the moisture-guiding filaments, and drying by hot air to connect the moisture-guiding filaments into a whole. The first skin layer 1 formed in this way has good moisture-conducting and air-permeable properties, and can improve the overall anti-wrinkle performance of the yarn.
