Abstract

A kind of weft-knitted fabric as male part in the surface type fixing haptics or female, the ventilating area (11b) that it is made into by a simple weft-knitted end silk (14) by a bonding pad (11a) and that has butt hook (15 ') or connecting ring (15).On the total length of this knitted fabric (10,10 '), bonding pad (11a) alternate each other with ventilating area (11b) to become a plurality of knitting.

Description

The present invention relates to a knitted fabric for use as a female or male part of a hook-and-loop fastening loop, that is, a surface-type fastening loop, for securing articles of clothing in predetermined positions.

For securing articles of clothing such as clothing, footwear, bags and gloves, a number of hook-and-loop fasteners, more recently also known as surface-type fasteners, have been proposed. Japan's "Open Utility Model Gazette" No. 63-91009 discloses a warp-knitted fabric with many rings on one side. The disclosed knitted fabric is woven with mesh or fretwork holes for proper coating on the back of the fabric. Layer, after the joints of the woven silk are consolidated together, it provides air absorption, or breathability. This prior art has the disadvantage that it is not technically and economically feasible to distribute a large number of holes evenly over the entire surface of a knitted fabric.

In view of the above-mentioned disadvantages of the prior art, the present invention seeks to provide a weft-knitted fabric with air-permeable zones, which can be produced with the highest efficiency and the lowest cost.

The present invention further attempts to provide a breathable weft-knitted fabric with female parts (i.e. rings) or male parts (i.e. hooks), which can be adjusted according to the air permeability and the separation strength of the female and male parts . Therefore, the fabric finished product of making according to the present invention will be able to be widely used as the surface type fastening loop of various clothing items, especially those items that need to absorb air such as shoes and gloves, or those such as mops and mats. Items that are easy to wash and dry quickly.

The above-mentioned features and advantages of the present invention will become more apparent from the following detailed description together with the accompanying drawings which illustrate a preferred embodiment.

According to the present invention there is provided a weft-knitted fabric for surface-type fixing loops, which consists of a connecting zone with a connecting device and a gas-permeable zone with many holes, along the length of the knitted fabric, the connecting zone and the gas-permeable The regions are identical to each other, and the courses are formed into multiple weaves, and the knitted fabric is coated with adhesive on its back without blocking the pores above.

Fig. 1 presents the present invention as a whole, is used as the perspective view of the weft-knitted fabric of a surface-type fixed loop female part;

Figure 2 is a view similar to Figure 1 except showing a weft knitted fabric used as a surface-type fastener loop male member.

Now see attached picture. First look at Fig. 1, which shows a weft-knitted female part 10, which is first woven into a cylindrical blank by a circular knitting machine with two sinkers of different layers, and then cut into sheet materials .

The knitted fabric 10 consists of a pile part 11 and selvage parts 12 , 12 . The plush part 11 spreads over most of the central region of the knitted fabric, while the selvedge parts 12 and 12 are on opposite sides of the plush part 11 and extend longitudinally along both sides of the knitted fabric 10 .

The plush portion 11 of the knitted fabric 10 is composed of a connecting area 11a and an air-permeable area 11b. The connecting area 11a is woven by about 210 counts of plush yarn 13, while the air-permeable area 11b is woven by 50-100 counts of base yarn 14. The plush yarn 13 and the base yarn 14 are all made of multi-strand yarns of nylon, polyester and polypropylene or similar plastic materials.

The plush yarn 13 in the connecting area 11a is woven into a plurality of rows of loops 15 by a high-level sinker (not shown) on the loop forming machine, and the loops 15 are arranged and extended in a transverse or weft direction, and are used as female connecting means. The loops 15 can be broken into mating hooks 15' on the male piece 10' of knitted fabric, as shown in Figure 2, in which case the pile filaments 13' are preferably single strands.

The base yarn 14 in the air-permeable zone 11b is woven into a flat weft-knitted web having a plurality of pores 16 to provide sufficient air permeability.

According to an important aspect of the present invention, the knitted fabric 10 is weft-knitted, with a plurality of interlaced joining zones 11a and air-permeable zones 11b laid across the weaving web, that is, all other weaving tracks are as presently illustrated. On the full length of the plush portion 11 of the knitted fabric 10, the number of the two alternate regions 11a and 11b can be conveniently adjusted according to the separation strength between the ring 15 and the hook 15' and the degree of air permeability required for a specific application. be changed.

The female piece knitted fabric 10 and the male piece knitted fabric 10' constituted in this way are covered with a suitable adhesive such as synthetic rubber or resin on their respective backs, so that all the knitting yarns are bonded together to ensure that the knitting The mesh maintains its shape and prevents misalignment or pulling out of the ring 15 . In this case, care must be taken not to allow the adhesive to block or seal the pores 16 of the gas permeable zone 11b. If necessary, the pores 16 can be kept open by air spraying.

The knitted fabric 10, 10' is cut along the selvedge portion 12, 12 to obtain a breathable surface type fastening loop.

The loop 15 of the attachment area 11a can be disassembled to enhance the bonded connection with the mating hook 15', for example by brushing it into individual strands.

Obviously, various modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described above.
