1. The shrinkage of wool: Under the condition of damp heat or chemical reagent, the wool fiber or fabric scale will open. If repeated frictional extrusion is carried out at the same time, the fiber maintains the root movement due to the directional friction effect, and the fiber entanglement is in a certain direction. Slowly creeping. The wool fibers are meshed into a felt, and the wool fabric shrinks tightly. This property becomes the fluffing property of the wool.
2, differentiated fiber: generally chemically modified or physically deformed, so that the fiber's morphology, physical and chemical properties and conventional fibers are significantly different, to achieve bionic effect or improve the performance of chemical fiber. Such chemical fibers that are innovative or have a certain characteristic to conventional fibers are called differentiated fibers.
3. Microfiber: A fiber with a small density of monofilament, also known as microfiber. According to the linear density range, it can be classified into fine fibers and ultrafine fibers. The fine fiber has low bending rigidity, and the obtained fabric has fineness, softness, good drapability, large specific surface area, good moisture absorption, lightening effect when dyeing, and soft gloss.
4. High shrinkage fiber: Chemical fiber with boiling water shrinkage higher than 15%. Depending on the degree of heat shrinkage, products of different styles and properties can be obtained. For example, high shrinkage polyester with a heat shrinkage of 15%-25% can be used to weave various enamels, embossments and jacquard fabrics.
5. Hygroscopic hysteresis: Under the same atmospheric conditions, the moisture regain rate-time curve and the moisture regain rate-time curve do not overlap at the end and have hysteresis. The equilibrium regain rate from dehumidification is always higher than that obtained by moisture absorption. Balance the moisture regain. This property of fibers is called hygroscopic hysteresis or hygroscopicity.
