Problems solved by technology

[0021] From the point of view of eliminating tape defects, the frequent occurrence of filament breakage defects in the in-line manufacturing process is unacceptable, however, it is difficult to reduce the cost of the source wire by increasing the strength of the filament or fiber or increasing the wire speed

example 1

[0076] 200 polyester multifilament threads with 1500 denier per 288 filaments (with a single thread fineness of 5.2 denier) and a strength of 10.5 g / d were used as polyester multifilament threads of small single thread fineness and used in the present invention The warp of the belt 1.

[0077] By using a bobbin as disclosed in Japanese Patent No. 2,630,567, the twisting process is performed so as to give various numbers of twists respectively to the same warp mentioned above, and the twisting operation is performed simultaneously, and each twisted thread is supplied to a Knitting machines are used as warp threads for weaving.

[0078] With the above operation, with a weft density of 20 wefts / 3cm (weft coefficient: 182), 750 denier polyester multifilament yarns were supplied as wefts 3 to the upper warp of the same knitting machine as described above, thus forming a weft with a thick weft density. Denim webbing. Finally, these tapes were subjected to dyeing processing and res...

example 2

[0081] A polyester multifilament thread with 288 filaments of 1500 denier (with a single thread fineness of 6.6 denier) and a tenacity of 10.8 g / d was used as the polyester multifilament thread with a small single thread fineness and as the warp thread 1 of the tape of the present invention.

[0082] By using a spool as disclosed in Japanese Patent No. 2,630,567, a twisting process is performed so as to give a twisting number of 120 t / m to warp yarns, and at the same time the twisting operation is performed, and the twisted threads are supplied to a knitting machine as warp yarns for weave.

[0083]In the knitting operation, the knitting machine forms the denim webbing using the warp 1 and the weft 3 described above, and when the denim is produced by the knitting machine, as shown in Table 2, by changing the number of wefts, the kind of wefts, and the wefts With different fineness and density, a variety of thick belts J to R are formed.

[0084] Some straps are dyed only, and...

example 3

[0090] In addition to the warp construction of the tape shown in Example D of the invention, a set of 16 polyester multifilament threads, each having 500 denier and 48 filaments and twisted at about 120 t / m, and a set of 16 Polyester multifilament yarns, each having 250 denier and 24 filaments and twisted at about 120 t / m, are respectively inserted into one end 5 of the belt 4 as warp yarns 6 therein, and the above-mentioned same multifilament yarn groups are respectively The other end 5' of the strap 4 is inserted as a warp thread 6 therein.

[0091] Then, if Figure 4 As shown, these warp yarns and appropriate weft yarns are woven into a tape in a predetermined weaving structure so that the shape of both ends of the tape can exhibit a substantially round shape and have a soft feeling.

[0092] In another embodiment, in addition to the warp profile of the tape shown in Example D of the present invention, a set of 32 polyester multifilament threads, each with 500 denier and 4...

Abstract

In a thin and light webbing having a high strength per warp yarn unit, maintaining abrasion resistance, and using as a warp yarn a very strong polyester multifilament yarn for a seat belt made by fine single-yarn fibers, the warp yarn is obtained by performing a twisting process of a high degree of twist on a polyester multifilament yarn made of fine single-yarn fibers so as to be highly bound. The polyester multifilament yarn of fine single-fibers is woven at the maximum stretch ratio in a yarn making process to obtain very-strong polyester fiber for a seat belt. A multifilament yarn and / or a monofilament yarn of polyester is / are used as weft yarns. By making the weft yarns and warp yarns cross each other so as to be woven in a belt like configuration, a webbing having a very high strength per unit of warp yarns, using low-cost base yarns, and maintaining abrasion resistance is obtained.

Description

technical field [0001] The present invention relates to a webbing used as a seat belt, said webbing used as a webbing being woven with warp and weft threads on a webbing-like member. [0002] More specifically, the present invention relates to a technique for obtaining a thin and light belt having high strength per number of warps and maintaining abrasion resistance, unlike conventional safety belts, which utilize Polyester multifilament yarns are woven from high strength, thin monofilament yarns that are not typically used in conventional seat belts, under twisting conditions, and are highly twisted middle. Background technique [0003] In general, belts used as safety belts have specific safety characteristics, such as specific tensile strength, elongation and durability or similar properties, and mainly utilize composite materials made of polyester or polyamide threads or fibers. The silk thread is used as the warp thread, and the multifilament thread or monofilament th...
