Loom let-off bobbin rack for wearing flat coarse warp woven fabric

Abstract

The let-off creel for weaving flat coarse warp fabric, such as large tow carbon fiber fabric includes several basic frames arranged in the loom breadth direction and in the back of the loom, and each basic frame has two work planes in 10-20 deg angle including one front work plane and one back work plane with yarn guiding ceramic holes 10-30 mm higher than those in the front one. Each of the work plane has 7 or 8 layers of 8 or 9 lines of bobbins mounted, with the bobbins in the lower layer are 5 mm over shifted relatively to those in the upper layer. The interval between the yarn guiding hook and corresponding bobbin shaft is greater than 250 mm and there is operating passage between the basic frames. The present invention has the advantages of homogeneous wrap tension, raised fabric breaking strength, reduced crossed wear, simplified creel structure and small covered area.

Description

technical field [0001] The utility model relates to the field of textile industry, in particular to a loom let-off creel for weaving flat thick warp woven fabrics, such as large tow carbon fiber woven fabrics. Background technique [0002] Large-tow carbon fiber woven fabric is a kind of carbon fiber reinforced skeleton material for composite materials, usually woven with rigid rapier looms, widely used in repairing and strengthening components of aviation and spacecraft, bridges, buildings and large structures. Because the carbon fiber bundle as the warp is very thick, the loom warp delivery system in the form of a weaving beam cannot meet the weaving needs of continuous and mass production. Therefore, the large tow carbon fiber warp yarns are directly drawn out from the creel and entered into the loom for weaving, which has become the best solution to replace the warp let-off of the weaving beam. This plan also cancels the warping process, which is beneficial to reduce th...

AI Technical Summary

Problems solved by technology

This type of creel leads to significantly uneven tension of the warp yarns when they pass through the expansion reed at the rear of the loom, and the twists and wear of the yarn increase, which has a very adverse effect on the mechanical properties of the fabric; and the creel occupies a large area, and workers operating route far
