Problems solved by technology

[0004] A few days ago, the traditional weaving method of changing warp-heavy flat fabrics mostly adopts the dobby shedding mechanism to weave, and one weft yarn is introduced into each opening, so the weft insertion rate (yield) is low

Embodiment Construction

[0016] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0017] A variable warp-heavy-flat fabric is based on plain weave fabric, and is obtained by extending different weave points along the warp direction to obtain floating lengths with different lengths. The fabric specification of this embodiment: JC80 S ×80 S 220×180 63″(JC7.38×7.38 866.1×354.3 160cm), the fabric structure is Changes are rebalanced.

[0018] In this embodiment, the plain weave cam mechanism and the four-color weft-supply air-jet loom with variable weft density electronic take-up and electronic warp let-off devices are used for weaving. The let-off amount and take-up amount of the loom change according to the set rule, and in accordance with the change of the let-off amount and the take-up amount, each opening is introduced according to the set weft insertion sequence, and the corresponding weft yarns of different numbers...

Abstract

The invention relates to a method for weaving variable warp rib fabrics with an air-jet loom. The method comprises: a weft insertion system of the prior air-jet loom is additionally provided with a weft yarn detection device; during weaving, a plain weave cam opening mechanism and a four-color weft selection air-jet loom provided with an electric reeling and electric run-in warp device with changed weft density are used. The warp run-in and the reeling amount of the loom change according to a set rule. With the change of the warp run-in and the reeling amount, in each opening, different number of weft yarn is led in according to the set weft insertion order, so the loom realizes the weaving of the changed weft rib fabric. The method has the advantages that: the variable warp rib fabrics is made by a method of introducing a different number of weft yarn in each opening, so the running speed of the loom is improved, the filling insertion rate and the yield is improved, the production cost is reduced and economic benefits of a weaving company is improved.

Description

technical field [0001] The invention relates to a method for weaving woven fabrics in the field of textiles, in particular to a method for weaving variable warped flattened fabrics on an air-jet loom. Background technique [0002] One of the goals pursued by modern weaving technology is efficient weaving with high yield, high quality and low consumption. Due to the characteristics of high speed, high degree of automation and good product quality, the air-jet loom has developed rapidly in recent years and has become the main equipment for fabric production. [0003] Among many factors that affect the efficient weaving of looms, the weft insertion rate of looms is a major factor. The weft insertion rate refers to the length of the weft yarn introduced into the shed per minute by the loom, and it is an indicator to measure the production capacity (output) of the loom. When the reed width of the loom is fixed, the weft insertion rate is directly proportional to the loom speed ...
