Development Of Duvetyn Product Based On Super Short-Quarter Cotton

Super short-quarter cotton is one new kind of cottons, which has short autumn and cheap price. It is appearance has very important significance to stabilization of cotton output of our country, solving contending soil between foodstuff and cotton and reducing cost of textile production. The subject mainly discussed and studied on the physical and chemical properties, spinning craft, weaving craft, back finishing craft and fabric performances of super short-quarter cotton fiber.Tested and analyzed physical and chemical properties of super short-quarter cotton fiber, such as length, degree of thinness, strength, degree of mature, trash content, water content, percentage of short fibers and sugar content and so on. The results shown that the advantage are high degree of mature and strength and low sugar content, the disadvantage are shorter length, thicker degree of thinness and more trash content.Researched on spinning craft of pure yarn based on the physical and chemical properties of super short-quarter cotton fiber, and optimized carding craft and yarn craft by orthogonal method. The results shown that: 1) Changing the speed of licker-in and doffer and the distance between cylinder and flats set remarkable influences the quantity of neps, percentage of short fibers and trash content. The speed of licker-in has the most influence on neps quantity, percentage of short fibers and trash content. Proper speed of take-in should be adopted in order to increase the line speed ratio between cylinder and licker-in; the speed of doffer has the most influence on trash content. 2) Changing the back space, back drafting multiple and roving twist coefficient of spinning drafting craft significantly influences breaking strength, fuzzy fiber of resultant yarn, and yarn irregularity. The three factors set remarkable influences to yarn breaking strength, back drafting multiple sets remarkable influences to yarn irregularity and the back space sets remarkable influences to fuzzy fiber of resultant yarn.Corduroy of super short-quarter cotton is succeeded developed by adopted the same fabric tissue structure, weaving craft and back finishing craft to common corduroy. Finally finding Corduroy of super short-quarter cotton has fresher color than common corduroy.tested results shown that corduroy of super short-quarter cotton has better tensile strength, warp orientation tearing strength, fleecy degree, thickness, endure degree, touching feel of cold or warm of fabric, heat preservation capability and air permeability than common corduroy. Common corduroy has better roughness, elasticity restore ratio, heat exchange capability and wicking property than super short-quarter cotton corduroy. They all have good wearability, wash-resistant colorfastness.
