Problems solved by technology
Most of the existing digital rapier looms can only weave fabrics with flat healds. When twisted healds are required for leno weaving, it is difficult to open the twisting shed, the height of the twisting shed is not enough, and the twisting and leakage are difficult. Many weaving phenomena and other difficulties seriously affect the production efficiency and product quality of the loom

Embodiment Construction
[0021] refer to figure 1 , figure 2 , image 3 and Figure 4 , the present invention is a novel hedging method for making and weaving leno fabrics on a digital rapier loom and a twisted heald combined hedging device adopted in the method, and a novel heald drawing method for weaving leno fabrics on the digital rapier loom Including the following steps:
[0022] Step 1: Adjust the tension regulator component 4, so that the twisted heddle combined hedging device reaches the hedging speed and the speed of the digital rapier loom is synchronized;
[0023] Step 2: Pass the twisted warp between the front base heddle 11 and the rear base heddle 21 of the next pair of twisted heddles 10, and pass the twisted warp into the threading hole 16 of the half heald 12 of the adjacent previous pair of twisted healds 10;
[0024] Step 3: Pass the ground warp out from the threading hole 16 of the half heald 12 of the last twisted heddle 10, and pass the ground warp between the front base he...

The invention discloses a novel drafting method for weaving lenos on a digital rapier loom and a combined leno heald returning device adopted in the method. An upper leno heald returning device and a lower leno heald returning device are combined into the combined leno heald returning device, by means of experimental optimization, leno weaving can be carried out on the digital rapier loom more conveniently and faster, the problem of weaving difficulty caused by unclear opening of a twisting and turning shed or insufficient opening height is reduced, and the production efficiency is effectively improved, which is beneficial for application and popularization.
Description
【Technical field】 [0001] The invention relates to the technical field of textile technology, in particular to the technical field of a novel hedging method for weaving leno fabrics on a digital rapier loom and a twisted heald combined hedging device used in the method. 【Background technique】 [0002] The rapier loom is currently the most widely used shuttleless loom. In addition to the characteristics of high speed, high degree of automation, and high-efficiency production of the shuttleless loom, its positive weft insertion method has strong variety adaptability and can adapt to The weft insertion of various yarns, and the rapier loom also has obvious advantages in multi-color weft weaving, and can produce yarn-dyed products with up to 16 color weft yarns. As shuttleless looms replace shuttle looms, rapier looms will become the main production machine for woven fabrics. Most of the existing digital rapier looms can only weave fabrics with flat heddles. When twisted healds ...
