Abstract

The utility model belongs to the improvement of a filter cloth matched with a press filter which is used for ore dressing in metallurgy and operation in petrochemical engineering. The utility model is characterized in that the fabric weave of the filter cloth is of a weft backed weave, each weave circulation comprises three warps and six wefts, the denier number of the warps used is 1600D-2200D, the denier number of the wefts is 1200D-1800D, the warp density is 280-320 per 10 cm, and the weft density is 130-160 per 10 cm. The utility model has the advantages of high warp density and weft density, and low water shrinkage ratio.

Description

Filter cloth for filter press

The utility model belongs to a kind of improvement for technics of metallurgy mineral dressing and the supporting filter cloth of the used filter press of petrochemical industry operation.

For industries such as technics of metallurgy mineral dressing and petrochemical industry LAROX-DF filter press commonly used, its used filter cloth needs from external import.The filter cloth of this import not only costs an arm and a leg, but also exists shortcomings such as low through weft count, that washing shrinkage is high is 3～4%, and the life-span is short.

The purpose of this utility model is the shortcoming at above-mentioned existence, and a kind of thread count height is provided, and washing shrinkage is low, the filter cloth of long service life.

Technical essential of the present utility model is: this filter cloth has through weft yarn, and the fabric tissue that it is characterized in that it is a filling-backed weave, and each tissue circulation comprises three warp thread, six roots of sensation weft yarn (weft yarn is three table latitudes, three back wefts); First warp thread is the 1st and shows latitude, the 1st back weft, the 3rd back weft below warp thread that the 2nd table latitude, the 2nd back weft, the 3rd table latitude are on warp thread; Second warp thread be the 1st back weft, the 2nd table latitude, the 2nd back weft below warp thread, the 1st table latitude, the 3rd table latitude, the 3rd back weft are on warp thread; The 3rd warp thread be the 2nd back weft, the 3rd table latitude, the 3rd back weft below warp thread, the 1st table latitude, the 1st back weft, the 2nd table latitude are on warp thread; Used warp thread dawn number is 1600D～2200D, and weft yarn dawn number is 1200D～1800D, and warp count is 280～320/10cm, and weft count is 130～160/10cm.

The utility model is compared with prior art: through weft count height, long service life; Washing shrinkage is low, is below 2%.Its cost is low, and is easy to utilize.
