What problems should be paid attention to when weaving high-density down proof cloth on air-jet looms

problems needing attention when weaving high-density down proof cloth on air jet loom:

1. The down proof cloth has a large tightness, the warp density should be changed, and the weft density is also close to the weft density. During weaving, the weft beating resistance is large, the weaving mouth moves greatly, and there are many warp breaks. The weaving process should adopt the principle of large tension, low back beam, and small opening

2. In order to prevent the back beam from swinging too much during beating up, the loose warp movement range is 0~24 electroslag pressure welding mm

3. The coiling roll should be sprayed with emery to increase the coiling holding force. The side support pricking ring should be high and fine to reduce the side support defects

4. The twisted edge shall be rope like twisted edge, high-density down proof cloth with large weft density. The warp yarn at the outermost side of the cloth edge is easy to relax. If the measurement data between the ground warp yarn and the twisted edge yarn is inaccurate, two edge yarns with withering tension can be added
