Problems solved by technology

[0002] Polyimide fiber has the advantages of fiber strength of 6-9g / D, elongation of 13%, and modulus of 72g / D, and it can be used in a wide temperature range. It can be used at 400°C--270°C. It can reach 3g / D, and the critical strength temperature is 560°C. It is one of the very few fibers used in this temperature range. It also has radiation resistance and good flame retardancy, but it has high insulation. When used in daily use, static electricity Seriously, it limits the scope of practical use. If the conductive property is changed by composite spinning, the spinning process is difficult to unify. The only way to improve its conductivity is to spin core-spun yarn to reduce static electricity accumulation.

preparation example Construction

[0012] The preparation method of the present invention is the following steps:

[0013] Choose oil agent or antistatic agent, spray evenly on the fiber pile, the dosage is 6-9%, and pile up for more than 24 hours. Because the fiber is in good order and there are few large impurities, it is mainly to open and remove impurities. Appropriate blowing, pay attention to the use of airflow when shooting miscellaneous, reduce cotton nodding, cleaning beater below 500r / min, carding cylinder speed 300-360r / min, licker-in roller speed 650-700r / min, doffer speed 17-19r / min, The sliver weight is 43-45g / m, the combed weight is 16-17g / 5m, and then the cotton fiber is cleaned, carded, pre-drawn, sliver, combed, drawn in the normal spinning process, and combed during blowing Needle beater speed is 480r / min, comprehensive beater speed is 820r / min, carding cylinder speed is 330r / min, licker-in speed is 850r / min, two drawing frames are adopted, core-spun yarn spinning process is in friction spinn...

Embodiment 2

[0020] Ingredients: 60% polyimide functional fiber, 40% natural cotton fiber, the preparation method is the same as that of Example 1.

[0021] In summary, the core-spun yarn of the present invention uses polyimide functional fibers and natural cotton fibers as raw materials, has a wide temperature range, and the addition of natural fibers improves cloth performance, and the friction spinning process is short and increases The dyeability of the yarn increases the production value of the product.

Abstract

The invention provides a brand novel weaving concept of the fabrics of polyimide and cotton fiber core-spun yarn variety; polyimide functional fiber and natural cotton fiber are used as raw material, and the process that leads the natural cotton fiber and the polyimide fiber into cleaning cotton, carding, pre-drawing, sliver lap, combing and drawing respectively is adopted. The spinning process is carried out on a friction spinning machine; polyimide fiber rod is put into the twisting area of a dust cage after being drafted, thus forming core yarns. Cotton fiber rod, after being drafted by a roller, is combed into single fiber condition by a combing roller and is coated outside the core yarns under the function of the dust cage, so as to form the structure of coating core yarns externally and shortening the technical process; meanwhile the adding of natural fiber improves the whole moisture regain of the yarns, reducing the electrostatic phenomena, improving the cloth performance and strengthening the dyeing ability of the yarns. The produced yarns can be used as clothing material, etc. for outdoor work, thus improving the producing value of the products.

Description

technical field [0001] The invention relates to a weaving method of core-spun yarn fabric, in particular to a weaving method of polyimide and cotton fiber core-spun yarn. Background technique [0002] Polyimide fiber has the advantages of fiber strength of 6-9g / D, elongation of 13%, and modulus of 72g / D, and it can be used in a wide temperature range. It can be used at 400°C--270°C. It can reach 3g / D, and the critical strength temperature is 560°C. It is one of the very few fibers used in this temperature range. It also has radiation resistance and good flame retardancy, but it has high insulation. When used in daily use, static electricity Seriously, it limits the scope of practical use. If the conductivity is changed by composite spinning, the spinning process is difficult to unify, and the conductivity can only be improved by spinning core-spun yarn to reduce the accumulation of static electricity.
