Abstract

PURPOSE:To obtain a less bulky magic fastener female member by inserting into or attaching to a slender width one or more synthetic fiber multifilament yarns having a number of loops, coils, entanglements and the like. CONSTITUTION:A constitution filament is mixing woven through the fluid disturbance treatment, as the female element of a plane body magic fastener female member, and loops, coils, synthetic fiber multifilament yarns having entanglement, etc., which has a single yarn fineness of 3 denier or more is used on the surface. In the fluid disturbance treatment, the synthetic fiber multifilament is introduced in the over-feed state into a fluid injection nozzle from one or two directions, and mixing-weaving-processed by the compressed fluid which is jetted into the fluid injection nozzle, and at least one filament for fluid disturbance treatment is inserted into weft, and engaged with a magic fastener male member, and a strong joint force can be obtained. Since the bulkiness is very small in comparison with the pile of the pile braided fabric as the conventional female member, the magic fastener female member itself can be made less bulky.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a magic fastener female member in the form of a sheet for use in the opening/closing part of everyday items such as clothing, underwear, shoes, and bags.

(Prior art) A magic fastener usually consists of a fabric in which a loop or arch-shaped female element is formed on one side of a base fabric, and a raised-shaped fabric such as a hook-shaped or mushroom-shaped bulging head shape that engages with the female element. This is a planar fastener used as an engagement tool for joining two pieces of fabric by applying surface pressure contact with a piece of fabric in which a conical element is formed on one side of a base fabric.

The female element of the magic fastener is usually formed from a knitted fabric having a loop pile of multifilament or monofilament made of synthetic fibers such as nylon or polyester on one side. The female material of the magic fastener formed from these loop pile knitted fabrics is made of a raised cone-like element made of a piece-shaped or mushroom-like expanded head shape of ordinary monofilament (monofilament of nylon 6, polyethylene, polypropylene, etc.) as a base fabric. When bonded with a magic fastener binding material formed on one side, a very strong bonding force can be obtained.

However, the joining of magic fasteners.

Depending on the application, a very strong bonding force may not be required, and in such cases, the adhesive area of male and female zippers has been reduced. When attaching it to a product, it is too small and it takes time and effort to attach it. Further, the female material of the magic fastener has a high bulk due to the structure of the loop pile knitted fabric, and depending on the application, it may be difficult to use because it gives a too voluminous feel, or even may not be usable.

(Problem H to be solved by the invention) The present invention has been made in view of the above-mentioned current situation, and has been developed to provide a material that has the bulkiness seen in the female material of a magic fastener made of a conventional loop pile knitted fabric structure. The purpose of this invention is to obtain a female material for a sheet magic fastener that does not

(Means for Solving the Problems) The present invention is distantly related to the above object and consists of the following nine-order configuration.

That is, the present invention provides a synthetic fiber multifilament yarn whose constituent filaments are mixed by fluid agitation treatment and which has a large number of loops, coils, entanglements, etc. of single yarn fineness of 3 denier or more on the surface.

The gist of the present invention is a sheet-like magic fastener female material, which is characterized by being inserted into or bonded to one or more thin cloths.

Hereinafter, one aspect of the present invention will be explained in detail.

In the present invention, as a female element of a one-sided magic fastener female material, constituent filaments are mixed by fluid agitation treatment, and the surface has loops, coils, entanglements, etc. with a single fiber fineness of 3 denier or more. A synthetic fiber multifilament yarn is used.

What is meant by the fluid agitation treatment here? 1 Synthetic fiber multifilament is introduced into a fluid injection nozzle in an overfeed state from one or two directions, mixed with compressed fluid that is injected into the fluid injection nozzle, and as shown in Figure 1. , many loops on the surface of yarn 1.

This is a processing method for forming coils, tangles 2, etc.

The synthetic fiber multifilament in the present invention is made of polyamide, polyester, polyacrylonitrile, polyolefin, etc., and the synthetic fiber multifilament composed of this is bonded to the female material of the magic fastener.

It is desirable that the single yarn fineness is 3 denier or more. When the single filament fineness is less than 3 denier, the constituent filaments are mixed by fluid agitation treatment, and when the female material of the magic fastener is joined to the surface where many loops, coils, tangles, etc. are formed and then peeled off, the formation This is undesirable because the loops, coils, tangles, etc. that have been formed will break and the bonding strength will decrease with repeated use.

Also, loops, coils, tangles, etc. of synthetic fiber multifilaments formed by fluid agitation treatment.

It is preferable that the size is larger and the number is larger than the bonding force with the female magic fastener material. The size is.

As shown in Figure 1, the height h in the vertical direction of the yarn length is 0.5
It is preferable that the number is 50 or more per 10 cm in terms of size on uapl. If the size of the loops, coils, tangles, etc. is less than 0.5 mm, it will be difficult to join the female member of the magic fastener to the hook-shaped or mushroom-shaped raised conical element, and a satisfactory joining force will not be obtained. This is not preferable because it makes it difficult to get caught.

Furthermore, if the number of loops, coils, tangles, etc. per 10 cm is less than 50, the bonding force will be poor due to the small number, which is not preferable.

In the present invention, one or more synthetic fiber multifilament threads (fluid disturbance treatment threads) having a large number of loops, coils, entanglements, etc. as described above are inserted into or bonded to a thin cloth.

To insert the above yarn into the fabric by weaving.

Using regular needle looms, rapier looms, water jet looms, air jet looms, etc.

It is possible to adopt a method of weaving while intermittent insertion into some of the warp or weft threads. for example.

Using the weaving structure chart shown in FIG. 3, weaving is carried out using a needle loom using the above-mentioned fluid agitation treatment system at position 1 to weave the narrow cloth shown in FIG. 2. In the fabric shown in Figure 2, two fluid disturbance treatment system threads were used.

Any number of pieces may be used as long as it is one or more. Usually 7 per inch
It is preferable to keep the number below this.

In this way, by inserting one or more pieces for the fluid disturbance processing system into the warp yarns or by inserting them at intervals into the weft yarns to form a planar body, it is possible to engage with the female member of the magic fastener and obtain a strong bonding force. I can do it. In this case, the greater the total denier of the fluid disturbance treatment system strips to be inserted, or the greater the number of strips inserted.

The bonding force can be increased.

Even if one or more fluid disturbance treatment system strips are bonded to a thin cloth or nonwoven fabric, the same bonding effect as a female material can be obtained as in the case of the above-mentioned fabric.

As the adhesive used when bonding to cloth, nonwoven fabric, etc., general synthetic resin adhesives 9 such as acrylic resin, polyurethane resin, vinyl alcohol resin, melamine resin, etc. can be used. The most suitable adhesive may be selected depending on the type of fluid disturbance treatment system strip to be bonded and the type of cloth or nonwoven fabric of the planar body.

The bonding method is to apply an adhesive to a width suitable for the thickness of the fluid disturbance treated thread to be attached to the surface of cloth or non-woven fabric, and then attach the above yarn on top of it. A method of applying pressure or heating can be adopted.

The present invention has nine or more configurations.

(for production) Many loops and coils on 9 surfaces as in the present invention.

When a fluid disturbance treatment system strip having entanglements, etc. is used as a joining element of a magic fastener female material, the bulk of the loops, coils, tangles, etc. of the fluid disturbance treatment system thread is compared to the pile of a conventional pile knitted fabric as a female material. Because it is very small,
The female material of the magic fastener itself can be made into a female material that is not bulky.

Additionally, if a filament with a single yarn fineness of 3 denier or more is used as a constituent filament of a fluid disturbance treatment system having loops, coils, entanglements, etc., the filament will be difficult to break when peeled off after joining with the female element. Therefore, repeated peeling strength can be significantly improved.

(Example) The present invention will be described in more detail with reference to the following nine examples. The performance of the samples in the examples was measured and evaluated by the following method.

(1) Thickness Adjust the thickness of the female material of the magic fastener to ON○5OKKI■
The thickness was measured using a thickness gauge DG811 manufactured by Kogyo.

(2) A tensile strength commercially available magic fastener female material (hook-shaped end, fastener width 25 mm) was engaged with a magic fastener female material prepared in the example in a length of 8 cm, and the joint was weighted with a 1.8 kg roller. 1. Next, using an autograph manufactured by Shimadzu Corporation, 2. Grasp the female material of the magic fastener and the top and bottom of the female material in the portions that do not meet at a distance of 10 cm, and measure the tensile strength at a speed of 10 cm/min.
The average value of the results of repeated measurements was determined.

(3) Peel strength: Join the male and female magic fasteners using the same method as above for tensile strength.Next, peel off 4 cm of one end of the joined end (total of 8 cm for the male and female) and divide it into upper and lower parts at an angle of 180 degrees. The peel strength was measured using an autograph under the same conditions as the tensile force, and the average value of the results of 5 repeated measurements was determined.

Example 1 A fluid agitation device equipped with Hefjet 341 model (air nozzle) manufactured by Heperline Co., Ltd. as an air injection nozzle was prepared, and polyester multifilament 50 was injected from one side.
Two 0 denier/48 filaments are aligned, and from the other one polyester multifilament 500 denier 74
8 filament single yarn was supplied to the air injection nozzle, and the feed rate at this time was 12% for the two aligned polyester multifilaments and 124% for the other polyester multifilament, and an air pressure of 7 kg/eat.
A fluid agitation treatment system was manufactured by agitating the fluid at a processing speed of 100 m/min and having a large number of loops, coils, tangles, etc. on one surface. This thread loop.

Check the height and number of coils, tangles, etc. F-IN08XT
BSTBR(SHIKISHIMA 5PINNING
COo, manufactured by LTD), the average height was 1
．． The number of 9 pieces per 1 mm was 73 pieces per 10 cm.

Next, in order to weave two of these threads into the female material fabric of the zipper, the weaving structure shown in FIG. 3 was used.

A fluid disturbance treatment system is used for the warp at that position, and polyester multifilament 25 is used for the other warps and wefts.
Using 0 denier 748 filament, warp density 63
The sheet magic fastener of the present invention is woven using a needle loom with 2 threads/inch of fluid disturbance treatment system (fluid disturbance treatment system thread spacing is 10 nm) and a weft density of 40 threads/inch. was manufactured.

For comparison with the present invention, when manufacturing the fluid disturbance treatment system strip in this example, instead of aligning two 500 denier/48 filaments (thick single filament fineness of about 10 denier) supplied from one side, 210 denier/48 filament Using 4 strands of denier/96 filament (single yarn fineness of approximately 2 denier), and replacing the 500 denier/48 filament single yarn supplied from the other side with 2 strands of 210 denier 796 filament, fluid A comparative sheet magic fastener female material (referred to as Comparative Example 1) was obtained in exactly the same manner as in this example except for producing the disturbance treatment system strip.

1. For comparison with the present invention, 2. In manufacturing the fluid disturbance treatment system in this example, the feed rate of the two aligned polyester multifilaments was set at 7%, and the feed rate of the other polyester multifilament single yarn was set at 7%. A comparative sheet magic fastener female material (hereinafter referred to as Comparative Example 2) was obtained in exactly the same manner as in this example except that the ratio was changed to 40%. In addition, the height of the loops, coils, entanglements, etc. of the fluid-disturbed yarn in the comparative example was 0.3 aun, and the number was 47 per 10 cm.

The performance of the female material of the sheet magic fastener of the present invention and for comparison was measured, and the results are shown in Table 1.

(Leaving space below) Table 1 As is clear from Table 1, the female material of the sheet magic fastener of the present invention has a thickness of only 0°74, and is generally made of a conventional loop or pile knitted fabric. Compared to the normal thickness of the female magic fastener, which is about 2 to 3 thick, it is about 1/3 of that thickness, so it is not bulky and can be used for a variety of purposes due to its characteristics.

Moreover, there was no extreme decrease in the repeated performance of tensile strength and peel strength, and the performance was sufficient to be used as a female material for magic fasteners.

Compared to this, in Comparative Example 1, the single filament fineness of the synthetic fiber multifilament was small, so loops, fills, tangles, etc. were cut, resulting in a decrease in performance during repeated use.
In Comparative Example 2, loops, coils, tangles, etc. were small and few, so only a low bonding force was obtained.

Example 2 The fluid disturbance treatment system thread having a large number of loops, coils, tangles, etc. obtained in Example 1 was coated on paper with a thickness of 0.2 mm and the same width as the thickness of the thread, manufactured by Dainippon Ink & Chemicals Co., Ltd. Hytran API-101H (urethane resin adhesive) at intervals of 1
Apply 2 coats at 0mm and bond together, temperature 150
℃ and a hot roll with a nip pressure of 2 kg/cnf to obtain 9 sheet-shaped magic fastener female parts of the present invention. The performance of the obtained female wood was measured and the results are shown in Table 2.

Table 2 As is clear from Table 2, the sheet magic fastener female material of the present invention has a thickness of less than 0.74 mm, and is generally a fabric magic fastener female material formed of a conventional loop or pile knitted fabric. Compared to the usual thickness of about 2 to 3 mm, it is about 173 mm thick, so it is not bulky and can be used for a variety of purposes due to its characteristics.

Moreover, there was no extreme decrease in the repeated performance of tensile strength and peel strength, and the performance was sufficient to be used as a female material for magic fasteners.

(Effects of the Invention) The sheet magic fastener female material of the present invention does not have the bulkiness seen in the conventional magic fastener female material having a structure of a loop or pile knitted fabric.

It also has sufficient practicality in terms of bonding performance.

Furthermore, since the female magic fastener material of the present invention can be produced at low cost, it can also be used for disposable products.
