Abstract

(57) [Summary] [Purpose] The present invention relates to a loop material for a zipper made of fiber, using a multi-needle sewing machine with good productivity.
It is intended to produce a material having good engagement and excellent peeling durability at low cost. [Structure] A woven fabric, a knitted fabric or a non-woven fabric is used as a base fabric, and long fibers of various fibers or their processed yarns or spun yarns are used as loop fibers, and an arbitrary loop is regularly formed on the base fabric by a multi-needle sewing machine. Things.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 According to the present invention, two or more multi-needle sewing machines are used to simultaneously and regularly plant various filaments at intervals of 1 mm or more and 10 mm or less using long fibers or processed yarns or spun yarns. The fibers of the lower thread planted are firmly fixed by the upper thread, so that there is no thread pull-out, excellent engagement and peel strength, and the use of a multi-needle sewing machine provides high production efficiency and a low price. This is extremely advantageous in terms of efficiency. Therefore, it is very effective to use it for disposable products.

[0002]

[Prior art]

 Conventional fiber fasteners generally use a hook having a monofilament tip formed into a key or a plastic formed with various projections on one side. On the other hand, as for the loop material, there is a method of weaving or knitting monofilament fibers so as to generate loops, or a method of knitting long fibers into a knitted material and raising the loops to generate loops. Further, a material is used in which a loop is generated in the nonwoven fabric by a needle punch machine, and this is heat-treated and fixed.

[0003]

[Issues to be solved by the invention]

 According to the conventional method of manufacturing a loop material, the processing steps are complicated, time consuming, productivity is not improved, and the price is limited. It is particularly disadvantageous to use it for disposable purposes. According to the present invention, a multi-needle sewing machine with high production efficiency is used, and various fibers can be easily used as the suture material. In addition to woven and knitted fabrics, non-woven fabrics such as spunbond can be used as the base fabric, so that it can be produced at low cost while maintaining high quality.

[0004]

[Means for Solving the Problems]

 The present invention uses long fibers of various fibers, their processed yarns, or spun yarns of various fibers, and uses a special multi-needle sewing machine to make nonwoven fabrics such as woven fabrics, knitted fabrics, and spunbonds as base fabrics. Is sutured to generate a loop, which is fixed. The feature of the present invention is that extremely high productivity is maintained while maintaining high quality, and low-priced products can be obtained. Therefore, use for disposable products is advantageous. Processing such as brushing and raising the surface of the lower thread side further enhances the quality effect.

【Example】

The first embodiment is as follows. Polyester long fiber false twisting yarn 200 denier, 72 filament yarn is spun into a polyester spunbond non-woven fabric 50 g / m ² by a multi-needle sewing machine (12 needles) with a needle spacing of 3/16 inch at stitch intervals of 3 mm. By suturing, a loop having a pile height of 1 mm was formed and fixed, and a loop material having good engagement and peeling durability was obtained. The second embodiment is as follows. Polyester staple fibers 3 denier 64m m50%, polyester staple fibers 6 deniers 64Mm50% and cotton mixing, a woolen yarn 10th, which multi-needle sewing machine 4-inch polypropylene spunbond nonwoven 50 g / ^{m 2} as a base fabric (12 Using this needle), stitches were stitched at intervals of 3 mm, the height of the loop was set to 1 mm, and a loop material having good engagement and peeling durability was obtained.

[0006]

[Effect of the invention]

 As mentioned in the previous section, mass production became possible easily by using a multi-needle sewing machine with high production efficiency. Also, with this multi-needle sewing machine, it is not necessary to rewind the thread into a reel or the like in advance, as in the case of knitting with a warp knitting machine, either long fiber processed yarn or short fiber spun yarn as a material for the loop portion. It is extremely efficient because it can be fed directly to a multi-needle sewing machine. Therefore, it is advantageous in cost. Regarding the performance, the desired spacing, width, etc. of the loops can be set regularly to the desired base cloth, so the desired engagement and peeling durability can be achieved by selecting the type of fiber. Character can be obtained. From the above, it is possible to supply low-cost loop material with good productivity while maintaining high quality, and it can be used for many purposes. It is particularly promising for disposable products. Further, by using a material in which performance such as antibacterial and deodorant is imparted to the fiber or the base cloth, a higher performance product can be obtained.

【Example】

The first embodiment is as follows. Polyester long fiber false twisted yarn 200 denier, 72 filaments as a lower thread (1), polyester spun bond nonwoven fabric 50 g / m ² as a base cloth (2), and a multi-needle sewing machine with a needle spacing of 3/16 inch. (12 needles), using a 50th count polyester sewing thread (3) as the upper thread, suturing at 3mm stitch intervals to create a 1mm high loop (1), fixing, engaging, peeling durability It has been found that a good looped fabric can be obtained. The second embodiment is as follows. Polyester staple fibers 3 denier 64m m 50% polyester staple fibers 6 deniers 64mm were cotton mixing 50% to make a 10th spinning yarn, based on the polypropylene spunbonded de nonwoven 50 g / ^{m 2} this lower thread (1) Using a 1/4 inch multi-needle sewing machine (12 needles) as the cloth (2), the 50th polyester sewing thread (3) is used as the upper thread and stitched at stitches of 3 mm, and the height of the loop is fixed. Was set to 1 mm, and a loop-shaped fabric for fasteners having good engagement and peeling durability was obtained.
