Embodiment 1

[0131] (warp and weft)

[0132] As the warp and weft, it is prepared to be formed of nylon 66, composed of single fiber 72 filaments with a single fiber fineness of 6.53 dtex having a circular cross-sectional shape, a total fineness of 470 dtex, a strength of 8.5 cN / dtex, an elongation of 23% and no Twisted synthetic filaments.

[0133] (Warping / shaft warping machine process)

[0134] Use above-mentioned warp yarn, utilize warping machine to make warp yarn beam with beam warping machine tension 40g / piece, utilize beam warping machine to make warp beam with beam warping machine piece 75g / piece.

[0135] (weaving process)

[0136]Using the above-mentioned warp beam and the above-mentioned weft yarn, using a water jet loom, the weaving density of the warp yarn is 51.2 / 2.54cm, and the weaving density of the weft yarn is a base fabric of 51.0 / 2.54cm. The warp tension is adjusted to 100g / root, and the loom rotating speed is 730rpm. The contact pressure adjusting member is used i...

Embodiment 2

[0141] A base fabric was produced in the same manner as in Example 1 except that the weaving conditions described in Table 1 were changed. In addition, in Example 2, the coating process was not performed. The results are shown in Table 1. In addition, in Example 2, the maximum swing width of the feed roller during weaving was 200 μm, and the weft flying peak tension generated by the tension imparting member was 1.15 cN / dtex.

Embodiment 3

[0143] A base fabric was produced in the same manner as in Example 1 except that the weaving conditions described in Table 1 were changed. In addition, in Example 3, the coating process was not performed. The results are shown in Table 1. In addition, in Example 3, the maximum swing width of the feed roller during weaving was 148 μm, and the weft flying peak tension generated by the tension imparting member was 0.44 cN / dtex.

Abstract

A kind of base cloth, the coefficient of variation CV1 (100×standard deviation / average value) on the length direction of its weft direction decomposition yarn strength is below 3.0%, the variation coefficient CV2 on the length direction of the weft direction decomposition yarn elongation rate (100 ×standard deviation / mean value) is 4.0% or less.

Description

technical field [0001] The present invention relates to a base fabric, a jet loom and a method for producing the base fabric. More specifically, the present invention relates to a high-quality base fabric with little variation in strength and elongation, a jet loom capable of reducing the amount of lint generated when producing such a base fabric, and a method for producing the base fabric. Background technique [0002] In recent years, when weaving by jet looms, weft spinning speed has increased in order to improve production efficiency. In general, the length measurement (the length of the beat-up weft yarn) in the jet loom is performed by a length measurement device attached to the loom. On the upstream side of the weft yarn flying out from the nozzle, the length measuring device pinches the weft yarn by two rollers, a feed roller and a length measuring roller, and then sends the weft yarn toward the nozzle. [0003] However, in a loom such as a jet loom, processes such...
