Description

I 1

The invention relates to knitwear with the manufacture of, in particular, to the manufacture of knitted fabrics, used mainly and the quality of the filter material.

The chain of the invention is to improve the operational properties of knitwear when it is used as a filter.

Figures 1 and 2 depict embodiments of the proposed knitwear, in Figs. 3 - section aa in figure 1, figure 4 - section bb in figure 2.

The culinary weft and base knitwear includes rows 1 and 2 of the surface, weft threads 3, t and threads 5 of the warp. The warp threads 5 are located between the hinge posts and are fastened on the seamy side with the stitches 6 and 7 of the stitches, and the ascending webs 3 and 4.

Weft threads and smooth surface threads have different linear density. The ratio of linear weights of weft yarns and smooth surface yarns is in the range of 0.2-6, while weft yarns of lower linear density are covered by smoothing fibers of lower linear density, and weft yarns of greater linear density are covered by large smoothing threads. The combination of individual.

linear yarn density. 3 and 4 weft and strands 1 and 2 of the surface make it possible to create protrusions (reefs) and cavities on the surface of the web, which increases the tightness of the sediment layer on the material surface.

PRI me R. A circular filter sleeve was made on a round MAP 9 class MAPINE with four hall systems. The main liners with a linear density of 72 tex 2 were used in the filling station, the linear density weft yarns of 72 tex 4 and 72 tex and loop-forming yarns

fS 72 tex 3 and 72 tex.

Weft threads 72 Tex 4 and loop-forming threads are threaded into the first and second systems

20 72 tex 3, and in threads 3 and 4 of the system weft threads 72 tex and loop-forming threads 72 tex. The weave pattern corresponds to FIG. A web with protrusions and depressions was obtained, oriented in the direction transverse to the web axis.

The canvas is tested on a filtration plant when filtering cement sand. At the same time, the dust collection efficiency is 99.6% compared to 98.6% using the known web.
