Imitation wool composite textured yam and method for producing the same
The invention discloses a wool-like composite textured yarn and a manufacturing method thereof. The composite textured yarn is provided with a core-sheath structure, and a core part and a sheath part of the composite textured yarn have different filament length differences and different extents. The manufacturing method is as follows: 2 POYs are taken as raw materials, wherein one POY raw material is heated to be stretched by a heater between a first yarn feeding roller and a second yarn feeding roller, and merged with the second POY raw material in front of the second yarn feeding roller, enters into a network nozzle between the second yarn feeding roller and a third yarn feeding roller by means of certain overfeeding, forms a network through air blowing and twisting, and is heated, stretched and textured to form the composite textured yarn. The prepared yarn has low manufacturing cost; and textile fabrics which are woven by the yarn after twisting have good wool-like effect, soft, dry and comfortable hand feeling and good rebound resilience and color emissivity after being subjected to alkali decrement, and are good fabrics of black formal dresses.
