Abstract:

In order to investigate the weaving control method of fabric without repetitive weaving regular rule for varp and filling yarn, the concept of random fabric was proposed with random lifting of heald frames as the mechanism based on the binary expression of the lifting state of heald frames, the weaving control methods of random fabric were proposed, and warp and weft interweaving characteristics of different weaving control methods were analyzed. The random fabrics were simulated using fabric design software, and their weavability was discussed. The fabric samples were woven by a fabric sampling machine, the interception characteristics were verified. The results show that by the random control of the lift movement of heel frames, random fabrics can be woven into irregular and non-curculating. Real-time random control can be used and the methods of pre-generating weaving sequence can also be used when the random fabrics are woven. Put-back sampling and non-return sampling can be employing when generating randomized weaving sequence, which controls to weave non-limited and limited random fabric, respectively.  Warp floats and weft floats with different lengths are distributing randomly on the random fabric surface, and many protruding three-dimensional stripes appear along the weft direction of the fabric, showing good permeability and tear resistance to the fabric. The interlacing numbers of the heald frame have little difference when weaving randomly.

Key words: random fabric, weaving control method, interlacing characteristic, weavability
