Technical method for eliminating defects of sparse and dense ways of textile temple

Abstract

The invention, which belongs to the technical field of weaving of twill-weaving textiles, relates to a technical method for eliminating defects of sparse and dense ways of a textile temple. When 6 / 6 twill-weaving fabric is woven, a used heald frame includes 14 pages of heald frame units and has 12 fells during the movement of the heald frame. The method is characterized in that the lifting rule ofheald pieces is as follows: every two heald pieces carry out heald lifting in an up-down manner. According to the invention, on the basis of improvement of the pattern card map and the heald threading map, the every two heald pieces carry out heald lifting in an up-down manner based on a flying threading method, so that a phenomenon that the front and rear heald frames ascend or descend simultaneously is avoided. Gaps of wefts at the two sides of the cloth surface are eliminated and the defects of sparse and dense ways are reduced, so that the product quality is improved.

Description

Technical field [0001] The invention relates to a technological method for eliminating the defects of the sparse and dense roads of the textile temple, which belongs to the technical field of twill weaving. Background technique [0002] When the Toyota JAT710 air-jet loom is weaving long twill fabrics with floating lengths such as 6 / 6, the heald frame continues to rise and continue to fall, resulting in a large change in the tension of the single warp at the changing structure, such as: C50*C40 / 2*128*75 *66 shirt fabrics have high warp density and high quality requirements. Under normal circumstances, the heald frames are drawn by the forward-through method. When the healds are drawn, the heald frames are drawn in accordance with 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 are drawn up in sequence, so that the first 6 pieces (3-8 pieces, except for the edge weaves) in the same weave will rise (or fall) and the rear at the same time There are many heald frames with 6 (9-14 piec...

Problems solved by technology

[0002] When Toyota JAT710 air-jet loom weaves twill fabrics with 6 / 6 floating length and long length, the heald frame continues to rise and fall, resulting in a large change in tension at the weave where a single warp yarn changes, such as: C50*C40 / 2*128*75 *66 shirt cloth has high warp density and high quality requirements. Under normal circumstances, the heald frames are threaded through the healds in a straight-through method. 7, 8, 9, 10, 11, 12, 13, and 14 are sequentially lifted, so that the first 6 pieces (3-8 pieces, except for 1 and 2 pieces are side fabrics) in the same weaving mouth rise (or fall) and the rear at the same time. 6 (9-14 pieces) The number of heald frames that are lowered (or raised) at the same time is more, resulting in a larger difference in warp tension due to tissue transformation, and because cotton fabric yarns have a certain elastic expansion rate, resulting in broken warp and weft yarns Or when dealing with other problems, when the machine is shut down, there will be a gap between the cloth weft yarn under the temples on both sides of the weaving fell and the subsequent weaving weft yarn, forming dense road defects on the cloth surface of the temple, which seriously affects product quality
