Technical Field

The utility model relates to a textile sector, in particular to novel flame-retardant yarn of vortex spinning.

Background

With the continuous progress of society, textile technology and textile equipment are continuously developed, new yarns are continuously appeared, and vortex spun yarns are one of the most attractive yarns. Vortex spinning is a new technology in the existing spinning system, compared with the traditional ring spinning: the method has the characteristics of short spinning flow, high production efficiency, online quality monitoring, high automation intelligent degree and the like, and also has the advantages of greatly reducing labor, reducing yarn hairiness and the like. Therefore, the vortex spun yarn is processed into needle and cotton fabrics, and has the advantages of smooth cloth cover, less hairiness, good wear resistance, good fuzz and pilling resistance, bright color, moisture absorption, quick drying and the like. At present, the vortex spinning technology is researched a lot at home and abroad, but the research on the linear performance of the vortex spinning is less.

The flame-retardant textile is obtained by flame-retardant finishing of common fabrics, and has no permanent flame retardance due to no washing fastness. And the flame-retardant textile is spun into flame-retardant yarn by adopting flame-retardant fibers, so that the flame-retardant yarn has permanent flame retardance, but the flame-retardant yarn has unsatisfactory flame retardance, poor serviceability and high price.
