Problems solved by technology

[0002] The high-count yarn changes the physical and mechanical properties, especially the strength of the yarn decreases with the increase of the count. When blending cotton, a reasonable cotton blending process is selected, and the yarn is even and dry, but when the yarn count is high After 100 or 120 counts, the difficulty of weaving will increase, and the weaving performance of high-count yarns will be poor after they are formed into yarns alone. good application

preparation example Construction

[0008] The preparation method of the present invention is the following steps:

[0009] The high-count yarn is used as the yarn core, and the yarn count is between 100-160. Since the current two-way covered yarn spinning equipment and technology cannot directly spin high-count yarn, it cannot be fed in the form of roving or fiber sliver. For spinning, high-count spun yarn can only be fed during production, the feeding speed is 50-100m / min, the transmission ratio between the feeding roller and the drawing roller is between 0.98:1-1:0.98, and the polylactic acid fiber filament As the outer covering yarn of the covering yarn, the upper area of ​​the spinning machine is the A area, and the lower area is the B area. Select A and B to cover the high-count yarn at the same time, or only one of them can be used. Areas are covered, preferably A and B areas are respectively coated with high-count yarns at the same time, wherein A area covers the yarn core in the Z direction, B area cove...

Embodiment 2

[0016] Ingredients: 87% of 100 pure cotton spun yarns, 13% of polylactic acid fiber filaments, and its preparation method is the same as in Example 1, except that the transmission ratio between the feeding roller and the yarn drawing roller is 1: 0.98.

[0017] In summary, the covered yarn of the present invention uses pure cotton high-count yarn as the yarn core, polylactic acid fiber filaments as the outer layer covered yarn of the covered yarn, and the strength of the yarn reaches 8%-15%. The hairiness of the yarn is improved, and the weavability of the high-count yarn is guaranteed.

Abstract

The invention provides the spinning method of a wrap yarn with the yarn core consists of high count yarn. The invention uses pure cotton high count yarn as yarn core and polylactic fiber filament as the outer layer of the wrap yarn; wrap yarn technology is adopted to process the high count spun yarn; wrapping filament wraps the spunbonded fabrics bidirectionally at the outer layer of the spun yarn; due to the adding of the filament, the gained wrap yarn improves the strength of the yarns by reaching the strength to 8 percent through 15 percent; meanwhile the filoplume of the yarns is improved, the weavability of the high count yarn is ensured and the weavability of the high count yarn and the producing value of the products is improved.

Description

technical field [0001] The invention relates to a spinning method of a covered yarn, in particular to a spinning method of a covered yarn whose yarn core is a high-count yarn. Background technique [0002] The high-count yarn changes the physical and mechanical properties, especially the strength of the yarn decreases with the increase of the count. When blending cotton, a reasonable cotton blending process is selected, and the yarn is even and dry, but when the yarn count is high After 100 or 120 counts, the difficulty of weaving will increase, and the weaving performance of high-count yarns will be poor after they are formed into yarns alone. good application. Contents of the invention [0003] The object of the present invention is to provide a method of spinning the covered yarn whose yarn core is a high count yarn woven by the reduction method. [0004] The technical scheme provided for realizing the present invention is: [0005] A method for spinning covered yarn...
