Description
Technical Field

Background
Three-dimensional crimped fibers, also known as spiral crimped or stereo crimped fibers, are fibers that are spirally crimped. The conventional process for crimping the chemical fiber staple is to mechanically squeeze the fiber in a crimping box at a high temperature and in a wet (nozzle) state to produce a crimp, so that only a planar zigzag crimp is obtained, the crimp elasticity is poor, and the crimp shape is not easily maintained. Later, when the microstructure morphology of wool is studied, the cross section of wool fiber is in a bi-component structure, and the fibrils, the crystal area, the amorphous area and the like in the two components are different in properties and arrangement, so that shrinkage difference is caused, and the wool is forced to be spirally curled. According to the teaching, researchers design a novel composite spinning process to grind the composite fiber into parallel bi-component composite fiber, so that the composite fiber generates spiral three-dimensional winding after heat shrinkage. In addition, under the single screw spinning condition, the spinning technology is changed, an asymmetric cooling mode is adopted to generate difference in the cortex structure, and the three-dimensional curled fiber can be prepared, has a memory effect and is durable in curl form, and if the fiber is wet, the number of curls is reduced but can be recovered after drying. The three-dimensional crimped fiber has stronger fluffiness and warmth retention property, more comfortable hand feeling and improves the cohesion force and the dimensional stability of the fabric during processing of the fiber.
