Technical Field
The application relates to the technical field of textile, in particular to wool fibers, a preparation method thereof and a woolen sweater prepared from the wool fibers.
Background
The wool fabric has the advantages of softness, warmth retention, good elasticity and the like, but also has the defects of easy pilling, fulling, deformation and the like. The main reason for the wool fabric to develop fulling is the directional friction effect produced by the wool surface flakes. Under the combined action of wet, heat and mechanical external force, fibers are mutually inserted and entangled, the fabric is felted, the fabric is tightly contracted, the size is changed, and the pile-milling phenomenon is generated. Therefore, the directional friction effect of the wool fibers is reduced, and the wool fiber is a precondition for shrink prevention of wool fabrics.
In the related art, the method for reducing the directional friction effect of the wool fibers mainly comprises a decrement method and an increment method. The method for reducing the scale comprises the steps of peeling the scale, removing all or part of the scale layer on the surface of the wool by corrosion, and specifically comprises a chlorine oxidation method, a potassium permanganate method, an enzyme treatment method and the like. The chloridizing method is used for stripping scales on the surface of the fiber through chloridizing, so that the interaction between a scale layer and the fiber is destroyed, wool velvet is easily damaged, and serious environmental pollution is generated; the potassium permanganate has strong oxidizing capability and is extremely easy to cause damage to wool fibers; and the enzyme treatment method has high operation difficulty, and the enzyme performance and the treatment program are difficult to accurately control. The increment method is to cover the wool scale layer, and the scale layer outside the wool fiber is covered by resin, sol gel, nano particles, ion crystals and the like. The fineness of the wool fiber obtained by the current incremental processing is obviously increased, the uniformity and the straightness of the surface of the wool fiber are poor, and the spinnability and the softness are reduced. In order to overcome the defects of the wool anti-milling treatment process, a wool fiber, a preparation method thereof and a woolen sweater prepared by adopting the wool fiber are urgently needed to be studied.
