Problems solved by technology

The problem of the Jacquard loom vinylon harness is that it is sensitive to changes in air humidity. After it is installed on the jacquard loom, once the air around the loom is dry, the harness will be shortened due to dehumidification, and when the air around the loom is humid , the length of the thread will be elongated due to moisture absorption
The product is sold to the weaving factory. Due to the large change in the stretching of the harness, it directly affects the normal production of the loom. Especially in the season of yellow mold in the south of the Yangtze River, the factory has a strong reaction. The stretching rate of the harness during this period It is particularly large, which seriously affects the shed definition of the loom, greatly reduces the weaving efficiency of the loom, and is quite easy to cause defects in the warp direction of the fabric, causing constant disputes between harness manufacturers and harness manufacturers.

Embodiment Construction

[0029] The raw material of the vinylon oil flower through silk thread of the present invention:

[0030] The light yellow hose vinylon yarn and the white vinylon filter tow are all produced by Sichuan Vinylon General Factory. The light yellow hose vinylon yarn is 29.5 tex, the single yarn twist is 490 twists / m, and the white vinylon filter is The tow is 29.5 special single yarns, and the twist is 490 twists / meter. Manufacture vinylon oil flower through-filament threads for jacquard looms, with a total density of 29.5 tex x 9 strands (together 265.5 tex). The 29.5 special vinylon yarn specially used for the light yellow water hose is used as one of the materials for the manufacture of the vinylon oil flower harness thread of the jacquard loom to increase the initial modulus of the harness yarn and form a vinylon flower cable with yellow and white as the logo.

[0031] The specific steps of the preparation method of vinylon oil flower through silk thread are as follows:

Abstract

The present invention relates to a kind of oiled polyvinyl harness flex for jacquard and its production process. The oiled polyvinyl harness flex is produced with light yellow polyvinyl yarn and white filtering polyvinyl yarn as material and through twisting, sizing and wax oil soaking. The produced oiled polyvinyl harness flex has yellow and white pattern, modulus 10-20 % higher than that of available one, small extension and less moisture influence.

Description

Technical field: [0001] The invention relates to the field of textiles, in particular to a vinylon harness thread on a shedding device of a jacquard loom and a processing technology thereof. Background technique [0002] In the textile industry, a jacquard loom generally has thousands or even tens of thousands of wires ranging from 2 meters to 4 meters depending on the width. In the weaving process, only when the expansion ratio of each harness is kept within a small range, can the shed of the loom be clear, weave smoothly and significantly reduce fabric warp defects. [0003] At present, the harness thread on the shedding device of the domestic existing jacquard loom is basically a harness thread made of the purchased vinylon filter tow as raw material. The processing technology is: the vinylon filter tow is processed into a single yarn with 430-450 twists / m and 29.5 characteristics through stretch cutting, drawing, roving and spun yarn (many factories directly purchase si...
