Problems solved by technology

Although this method works effectively, it cannot fundamentally solve the problem if the fabric itself cannot be wound up in a good shape. In addition, the following Patent Document 2 discloses controlling the resin spray according to the diameter of the fabric roll during winding. out-of-the-box method, but cannot be used on warp-ready fabrics
So, the existing method has not solved the problem

Embodiment 1

[0077] Fibers having a strength of 8 cN / dtex obtained by melt-spinning and thermally stretching polyhexamethylene adipamide resin were used as the warp and weft of the fabric. The fiber has a fineness of 470 dtex, 136 filaments, a boiling water shrinkage of 7.0%, and an interlacing number of 10 / m by water immersion. The warp yarns were warped without twisting and without glue, and warp yarn bundles with 4428 warp yarns were produced. The number of reinforcing yarns in the selvage portion was set to 4 on one side and 8 on both sides, the fineness of the reinforcing yarns were all set to 22 dtex, and the fineness of the leno yarn was also set to 22 dtex. In addition, the number of warp yarns entered into the reed (the number of warp yarns per one reed dent) was set to 1 / reed dent.

[0078] A water-jet loom was used as a loom, and the warp tension was set at 0.32 cN / dtex, and weaving was carried out using the same yarn as the warp for the weft at a loom rotation speed of 700 rpm...

Embodiment 2

[0083] The warp tension at the time of weaving was set to 0.21 cN / dtex, and the winding tension to the paper tube in the subsequent process was set to 0.7 N / cm, and it was implemented in the same manner as in Example 1.

[0084] The evaluation results of the obtained fabric rolls are shown in Table 1 below. The yarn tail length of the fabric is 4mm, the roll hardness of the fabric is 78° at the center, and the difference between the roll hardness at the end is 5°, and the unevenness of the fabric roll surface is 0.4%. In addition, the state of the fabric when the fabric roll is unwound , The quality of the fabric selvedge has also become a good result.

Embodiment 3

[0086] The fineness of the warp and weft yarns used is set to 700dtex, the monofilament is set to 105, and a warp yarn bundle with 3600 warp yarns is made, and the warp yarn tension during weaving is set to 0.38cN / dtext. Implementation under the same conditions as in Example 1.

[0087] The evaluation results of the obtained fabric rolls are shown in Table 1 below. The yarn tail length of the fabric is 5 mm, the roll hardness of the fabric is 82° at the center, and the difference between the roll hardness at the end is 4°, and the unevenness of the fabric roll surface is 0.7%. In addition, the state of the fabric when the fabric roll is unwound , The quality of the fabric selvedge has also become a good result.

Abstract

The present invention relates to a roll of wide-width high-density fabric. It is possible to provide a fabric roll that has a good roll posture and good quality near the selvage portion of the fabric even when the fabric is wide. A fabric roll, which is characterized in that it is a fabric roll formed by winding a fabric with a predetermined density for a plain weave airbag in which the warp and weft yarns are composed of synthetic fiber multifilament yarns on a core, and the width of the fabric roll is 2000 mm or more, the roll hardness of the central part of the fabric roll is 70° or more and 93° or less, the difference between the maximum value and the minimum value of the roll hardness of the end portion of the fabric roll is 10° or less, and the end portion of the fabric roll and the The difference in roll diameter at the center was within 1%.

Description

technical field [0001] The present invention relates to rolls formed by winding high density fabrics. In more detail, the present invention relates to fabric rolls of high-quality wide-width high-density fabrics suitable for airbag applications. Background technique [0002] In order to alleviate the impact on the human body in vehicle accidents, the installation of airbags in automobiles and other vehicles is being promoted. As airbags that absorb and ease the impact on the human body by expanding with gas etc. during a collision, in addition to the airbags for the driver's seat and the airbag for the passenger's seat, side curtain airbags, side airbags, knee airbags, and car seats In-room airbags, curtain airbags for rear windows, seat belt airbags for rear seats, etc. are gradually put into practical use. Furthermore, in order to protect pedestrians, installation of various airbags, such as airbags installed so as to inflate toward the outside of the vehicle, has also b...
