Sectional successive dust absorption opening system used for high-count short-fiber yarn warp-knitting weaving

Abstract

The invention provides a sectional successive opening dust absorption system used for high-count short-fiber yarn warp-knitting weaving. Dust vacuuming pipe is conveniently and sectionally assembled according to needs; the lengths of a sectional upper pipe and a sectional lower pipe can be cut according to practical dimensions of a dust absorption part of equipment; two ends of the sectional upperpipe which is cut according to needs are sealed; a solenoid valve is arranged on any one end, so that controllable connection and disconnection between the sectional upper pipe and the sectional lower pipe are realized; rapid connectors are arranged on two ends of the sectional lower pipe; sectional lower pipes of a plurality of dust absorption pipe groups are mutually connected by using tubes soas to form a dust absorption pipe group which covers a whole working face; all solenoid valves are controlled in a servo programmable manner; parameters of the number of openings, intervals and opening ranges can be controlled; the sectional lower pipes are connected with air sucking fans by adopting tubes; and through the sectional successive opening dust absorption system, excessive flying overaccumulation and excessive flying floating on a production site do not occur.

Description

technical field [0001] The invention relates to the field of warp knitted fabric preparation, in particular to a segmented sequential opening dust suction system for warp knitting of high-count spun yarns. Background technique [0002] In the textile field, it is generally considered that the yarn above 50Ne is a high-count yarn. Spinning and application of high-count yarns have become common. Fabrics produced with high-count yarns have a fine, soft, and flat appearance, and fabrics with extra-high-count yarns can even produce silk-like luxury and have high wearing comfort. [0003] High-count yarns and extra-high-count yarns have been widely used and promoted in woven fabrics. Domestic factories have been able to produce high-grade poplin cotton shirting fabrics with a warp and weft fineness of 140Ne. The application of weft knitting has already begun. For example, domestic and Japan have launched high-count and high-density weft-knitted cotton knitted fabric shirts. Howe...

Problems solved by technology

[0005] However, due to the complex structure of the yarn path system of the warp knitting machine and the narrow space for modification, it is impossible to effectively install the cruising dust removal device. Only suitable fixed dust removal devices can be installed in the three most important areas of the yarn bar, yarn splitting needle and loop formation. Because the warp knitting machine yarn path system often has a partition wall in the middle to enhance the rigidity of the system, it is impossible to install a tube-type vacuum tube from the beginning to the end. Secondly, the length of the working surface of the modern warp knitting machine is more than 4.5M, and There are often 2-5 yarn road working surfaces, so 2-5 suction pipes with the same length as the working surface are required. If such a long suction pipe is open all the time, even if it is equipped with a high-power high-pressure fan of 6KW or more, the suction The suction at the dust port is still very weak, unable to vacuum effectively
