Why wool fibers and their fabrics have shrinkage properties? What are their advantages and disadvantages? What are the sizes and sizes of wool fabrics?...
In the damp heat or chemical conditions, to be repeated as friction extrusion, the directional friction effect, keep the fiber finger movement and fiber entanglement in a certain direction slowly creeping into engagement. With wool felt, wool fabric shrink tightly.The wool fabric can be made into a rich, soft and warm fabric, but the shrinkage affects the dimensional stability after washing, and it is disadvantageous to the thin fabric which requires fine weaveThe size of cashmere is related to the quality of wool and external conditions (heat and moisture, mechanical external force)
The causes of cashmere wool shrinkage (1) fiber itself (or internal) wool is epidermal cuticle layer, because the scales exist, the friction coefficient of the friction coefficient is larger than the inverse scale direction along the scale direction, called the directional friction effect. The wool fiber has good elongation ability, elastic recovery, natural crimp make easy fiber entanglement.
