Multi-component Fiber Blending Ratio Relationship With The Yarn And Fabric Properties

With the enhancement of environmental protecting and health caring consciousness, it has come into style to pursue comfortable, beautiful and health care clothing. Blending and interweaving of different fibers can give play to each merit and overcome their shortcomings, which realize their performance complementary and offer the foundation to get the functional multicomponent yarns and fabrics with special appearances and wearabilities.Considering material properties, spinning techniques, equipments and the cost of products, cashmere fiber, fine count polyester and modal fiber were blended together to produce multicomponent yarns. Seven sorts of cashmere/fine count polyester/modal blended yarns were prepared with different blending ratio and the physical properties of these yarns were tested too. Regression mode was established based on the relations between each item of physical properties and blending ratio. And then wearabilities of seven sorts of knitted fabric made of cashmere/fine count polyester/modal blended yarns were tested. The main measurement items are listed as follows: tensile property, crease recovery property, bending rigidity, draping property and air permeability. According to the investigation of relations between wearabilities and blending ratio of blended fabrics, regression mode was established based on the relations between each item of wearabilities and blending ratio. Optimum blending ration can be assured corresponding to each item of wearabilities of blended fabrics through applying fuzzy mathematics, furthermore, blended fabric technology CAD has been developed so that blending ratio could be got directly according to each item of wearabilities.
