Problems solved by technology

[0003] In the prior art, the textile technology of Tencel fiber is spindle spinning. The Tencel produced by this production process is light and thin, but the strength is not enough. If the strength is sufficient, the Tencel is thick, easy to deform when folded, and has a limited service life, especially for weaving. When using waterproof canvas, the resulting waterproof canvas cannot achieve a good waterproof effect

Abstract

The invention discloses a spinning technology of synthetic fabrics for waterproof canvas. The technology includes the following steps: raw material selecting and blending; preprocessing; blowing; carding; and drawing. Tencel fibers with good quality are adopted, contradiction between thin and light of a product and strong force is resolved, handle of the product is soft, deformation does not occur when the canvas is folded, draping is good, service life is long, and various materials can be matched as required proportion to be blended. Different characteristics of various fibers are fully played, and the performance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning process of mixed fibers for waterproof canvas. Background technique [0002] Tencel fiber can be completely decomposed in the soil and has no pollution to the environment. The cellulose molecules contained in the raw material pulp during production do not undergo chemical changes, no by-products, and no waste is discharged outside the factory. It is an environmentally friendly or green fiber. Tencel The fiber fabric has good hygroscopicity, comfort, drape and stiffness, good dyeability, and can be blended with cotton, wool, linen, nitrile, polyester, etc., including ring spinning, air spinning, core spinning, spinning into All kinds of cotton and wool yarns, core-spun yarns, materials, etc. [0003] In the prior art, the textile technology of Tencel fiber is spindle spinning. The Tencel produced by this production process is light and thin, but the strength is not en...
