Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a high-speed weaving method for producing spun single yarn fabrics using a fluid jet loom.

[Prior technology] In the weaving industry, where competition is fierce, how to reduce weaving costs is a major issue, and therefore high-speed looms such as rapier looms, air jet and water jet looms, It is also used to manufacture textiles using single yarns, and in order to reduce costs by eliminating the sizing process, spun single yarns are woven without sizing.

In addition, when drawing the warp threads through the threads of the reed of a conventional loom, it was customary to pass at least two or more warp threads per warp to minimize damage caused by contact with the warp threads.

[Problem that the invention seeks to solve]

However, when weaving spun single yarn without glue, the fluff of the spun single yarn becomes an obstacle to smooth shedding.

To this end, efforts have been made to increase the number of twists or to burn the yarn in order to shorten the fluff of the spun yarn. Even if the yarn itself is used to shorten the fluff, the fluff is easily expanded due to friction from various guides, heddles, reeds, etc. during warping and weaving.

In the case of conventional shuttle looms and similar high-speed looms, in the case of rapier looms, the insertion of weft yarns is done through an object that actively carries the yarn, such as a shuttlecock, so the spun single yarns become entangled with their fluff, and to some extent Even if there was a delay in shedding, the object pushed the plurality of warps apart, that is, strongly divided the plurality of warps and advanced, so weaving was possible even with untwisted spun single yarns.

However, in weft inserting methods that use fluid force to blow the weft threads, such as air jets and water jets, only the weft threads fly, so if the timing of the slight shedding is delayed due to the adjacent warp threads becoming entangled with fluff, the weft threads may fly away. This causes a problem in that the number of stops of the loom increases significantly.

Therefore, the current situation is that efficient weaving using a glue-free spun single yarn using a fluid jet loom is virtually impossible.

The present invention solves the above-mentioned problems that occur when weaving with a fluid jet loom using a glue-free spun single yarn, and provides a weaving method with fewer loom stops based on the flight stoppage of the weft. With the goal.

[Means for solving problems]

The object of the present invention is to pass through a reed one warp yarn of each type at a loom rotation speed of 300r, p, and m in a non-thermal state when producing a spun single yarn fabric using a fluid jet loom. This is achieved by a characteristic weaving method.

In the weaving method according to the present invention, one warp thread is passed through each reed, so the entanglement of spun single yarns due to fluff during weaving is reduced, and as a result, even at high speed rotations of 300 r, p, m or more. The occurrence of delays during shedding is reduced, and the number of times the loom stops due to poor flight of weft threads is greatly reduced.

〔Example〕

The present invention will be described in detail below with reference to Examples of the weaving method of the present invention.

2Nr@ thread is used as warp thread, 100% cashmilon (2dx
51 m/m ) ring-spun yarn (twist coefficient α = 95)
1/Warp density 60 pieces/52No+ as weft yarn
A plain woven fabric with a weft density of 50 threads/inch was woven without glue using a water jet loom manufactured by Nissan Motor Co., Ltd., Model 41, at a rotational speed of 380 times/min and under different reeding conditions. The results obtained are shown in Table 1.

Table 1 As shown in Table 1, when one warp thread was passed through each reed, the number of stops due to poor weft flight was significantly reduced.

Back 1 plate 1 Ester cotton blend yarn 165 (65% ester, 35% cotton
) Spinning 1 single yarn as the warp and weft, a 2/1 twill fabric with a warp density of 75/inch and a weft density of 48/inch was made without glue using a JA-Is type air jet loom made by Toyota Automatic II & Machinery. Weaving was carried out at a rotational speed of 550 times/min while changing the reed passing conditions. The results obtained are shown in Table 2.

Table 2 As shown in Table 2, when one warp thread was passed through each reed, the number of stops due to poor weft flight could be significantly reduced.

〔Effect of the invention〕

Since the weaving method of the present invention is configured as described above,
By using the weaving method according to the present invention, it is possible to significantly reduce the number of times the weft yarn is stopped due to poor weft flight, and as a result, it is possible to realize cost reductions in weaving costs caused by the absence of glue and the use of high-speed looms. It has now become possible to implement it.
