Description

  The present invention discloses a method and product for weaving a shuttle loom fabric in the spinning technical field.

  Shuttle loom fabrics are now widely used in daily life and production materials such as clothing fabrics, decorative materials and industrial fabrics. Traditional shuttle loom fabric is based on the vertical crossing process of warp (longitudinal) and weft (transverse) spun yarns, and weaving, opening, weft insertion, weft driving, take-up, etc. It is woven in conjunction with the five major operations. In particular, all of the existing traditional wrinkles are vertical teeth, have the same tooth size, and all the teeth are arranged in a straight line and have the same density. At the time of weft driving, the kite is fixed with a kite so that the kite will not loosen.

As shown in FIG. 1, the existing loom is composed of a shaft 11, a back beam 12, a diameter thread fixing tip 13, an opening device 14, a reed tip 15, a weft inserter 16, a take-off roller 17, an introduction roller 18, and a cloth winding roller 19. Constitute. Shattle loom fabric (or machine fabric, referred to as fabric for short) is a constant discipline (textile structure) from warp 100 (longitudinal length) parallel to the fabric edge and weft 200 (lateral width) perpendicular to the fabric edge It is a piece-like assembly interwoven with. The principle of fabric formation is as follows:
The weaving shaft 11 is below the rear part of the loom, and parallel warps are wound thereon and transmitted by a radial threader. The warp yarn 100 is taken out from the weaving shaft, straddles the rear beam 12, passes through the diameter thread stopper tip 13 of the automatic diameter thread trimming device, the head 6 of the opening device 14, and the like, and is put into the scissor tip 15. The weft 200 is drawn into the weave by the weft inserter 16 (which is a shuttle in the figure), and is formed as the fabric 10 at the weft. Then, the fabric is drawn by the take-up roller 17 and wound on the cloth winding roller 19 by the introduction roller 18.

  The above-mentioned existing weaving: The fabric produced by the method and equipment is relatively monotonous in appearance, and both the diameter yarn and the weft yarn are 90 ° perpendicular crossing. Due to the straight intersection of the diameter yarn and the weft on the fabric surface, the yarns are arranged in a straight line in both the transverse direction and the longitudinal direction, and the densities are the same. Therefore, the patterns and types of the fabric are limited and there is no diversity.

  The present invention invents a weaving machine with a new design that avoids the simple weaknesses of existing fabrics and a clever design, further improves the product grade, and weaves fabrics with moderately curved and curvilinear patterns. Weaving methods and textile products are provided.

The step-type densely deformed kite is reciprocated up and down, and the diameter yarn and the fabric weave sandwiched between the kite chips are formed in a multi-variable inclined state, and sent to the fabric weaving port in the corresponding vertical and inclined state.
B, Opening: The loom opening is divided into two upper and lower layers based on the process conditions of the woven fabric to form a diamond-shaped weaving mouth, which is repeatedly operated up and down to give space for the introduction of the weft.
C, Weft insertion: When the weft insertion section is actuated, the weft inserter introduces the weft between the two-layer warp of the rhombus weave.
D. Raising and lowering weft threading: A straight slanted toothbrush mounted on the table slide tank moves up and down and swings forward and backward along with the bed table, and the introduced weft thread is struck into the weave.
E, Todoroki: The fabric is pulled out from the weave by the tortoise.
