Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is characterized in that when two pieces of cloth are stacked and pulled from side to side,
It concerns a processing method that prevents each cloth from slipping. That is, in detail, the present invention is directed to the prevention of slipping due to friction and resistance when two pieces of woven fabric, one knitted fabric, non-woven fabric, flocked cloth, etc. are pulled from side to side in a state of overlapping each other in clothing, materials, etc. The present invention relates to a processing method that exhibits a non-slip effect.

(Conventional technology) First, nine conventional techniques similar to the present invention.

There is something commonly called a hook-and-loop fastener.

This is because the two woven fabrics mainly exhibit resistance to the upper and lower peeling action, and in this case, the one that engages has a hook shape,
That is, it has a hook shape, which is essentially different from the method of the present invention. Differences between the present invention and conventional hook-and-loop fasteners and their drawbacks will be described below.

Therefore, for what is called a hook-and-loop fastener, the top and bottom two pieces of fabric are generally made of nylon 400 denier monofilament and formed into loops using a small or medium pile knitting machine, and then heat-treated to form the loops. After fixing,
This loop is canted with a special cutter to create a hook shape. or.

The other piece of cloth is, for example, a 280-denier nylon multifilament with about 20 filaments formed into a loop on a similar small to medium pile knitting loom, and these two cloths are engaged to form a hook-and-loop fastener. There is. but,
These hook-and-loop fasteners are manufactured by various companies, but the manufacturing process is extremely complicated.

The disadvantage is that the manufacturing cost is very high due to poor productivity. In addition, it is difficult to produce a material having a wide width as in the present invention.

Therefore, there is no other way than to use it as a small part.
Currently, only strategies for increasing the strength of binding are being studied. In addition, the two pieces of cloth are densely knitted to fix the pile, and are heat-treated, so the texture is much harder than that of ordinary clothing.

Due to these factors, the applications of hook-and-loop fasteners are limited.
It has the disadvantage that it is difficult to use for inexpensive disposable products.

On the other hand, the anti-slip cloth of the present invention is simple and easy to manufacture, and can be manufactured at low cost.

It can be used with small parts (~), and its texture is as flexible as general clothing, so it can be used on large areas, and it is different from conventional hook-and-loop fasteners in terms of structure and be.

(Construction 9 of the invention) The manufacturing method of the present invention overcomes these conventional drawbacks.

This was achieved as a result of numerous studies in accordance with the purpose, and the details will be explained below.

First, to give an overview, there are 9 knitted fabrics manufactured using long fibers, short fibers, etc. of thermoplastic synthetic fibers, etc., which have been made fluffy by brushing, or nonwoven fabrics that are naturally fluffy, or flocked fabrics. etc. may be left as they are, and this method is characterized by creating pill clusters on the surface by fluffing these fluffs, and the base fabric having these pill clusters is called A fabric. A base fabric having loop fluff on its surface so as to be caught is called a B fabric.

(b) First, let's talk about cloth A.

The term "thermoplastic synthetic fibers" as used herein includes all synthetic fibers that exhibit plasticity and properties when heated, such as polyester, polyamide, polyacrylic, polypropylene, polyethylene, and polyvinyl chloride.

This refers to polyvinylidene chloride, etc., but is not limited to only those listed here. The woven fabric, nonwoven fabric, flocked fabric, etc. that are generally used for clothing can be used as they are.

In the case of a single knitted woven fabric, either long fibers or short fibers may be used.

In addition, the fiber thickness of the raw yarn used for 9 fluffs is 50 denier, 24 filaments; 200 denier, 20 filaments, etc. Single yarn denier can be used from 1 denier to 10 denier, but considering the texture, 1 denier from 5
One around 1 denier is good.

Regarding the density of the woven fabric 9, sufficient effects can be obtained within the range used for general clothing. Here, if we classify the base fabrics used for fabric A, we will first classify them into the following categories: 1- refers to those that are generally referred to as woven and 2-knit fabrics, and 9 refers to those that do not have fluff.

- In the case of textiles, the structures include plain weave, twill, and satin weave.

In the case of warp knitting, half weave, suede weave, satin weave, and circular knitting are used.

Flat knitting refers to general knitted fabrics, as well as non-woven fabrics that are manufactured to avoid fuzz.

Next, the woven fabric 1 belonging to the second category refers to one with a pile structure.

The third category refers to gray fabrics with fluff, such as mokento, velvet, double raschel, and cut pile, whose loops are cut during weaving and knitting, and the needle punch method is used when producing flocked fabrics and nonwoven fabrics. Refers to something made with fluff.

Of these three categories, those that belong to the first type are those that are 1-
5. Make the fluff as fluffy as possible.

The lying fluff is also made to stand up, and if necessary, shearing is done using a shearing machine.

The second type involves cutting the pile using a shearing machine.

Also, those belonging to the third category do not require any special treatment because they have fluff.

In this way, fluff is generated on the surface of the base fabric using various methods, and then the fluffing is performed.

(b) Regarding cloth B, cloth A was required to be made of thermoplastic fibers, but cloth B does not need to be made of thermoplastic fibers, and any material that can engage the pill groups of cloth A can be used. good. Fabric B is a fabric that belongs to the first base fabric of the fabric A above, and 2 knitted fabrics using short fibers, 2 knitted fabrics using long fibers are 1 fluff, raised to create loops, and brushed. A second object can be engaged with that loop. Those belonging to the third category cannot generally be engaged with A fabric, but nonwoven fabrics made using the needle punch method can be engaged as they are.

These textiles and items are refined and dyed as usual.

After processing such as printing to adjust the quality of the 9-knit woven fabric, the 9-knit woven fabric undergoes each process depending on the type of 9-knit fabric described above, and then is fired.

It goes without saying that these processes are carried out in the same steps as those for ordinary two-knit woven fabrics.

Both A and B fabrics are commonly processed fabrics.

It can be manufactured into knitted fabrics of any width and length.

(c) Next, let's talk about Keyaki.

There are two types of burning devices: one using flame, and one that slides the hair in contact with a hot plate, but either method can provide a sufficient anti-slip effect.

In general, combustible fibers such as natural fibers and recycled fibers were used for sintering in the case of woven fabrics. This is done for the purpose of removing surface fuzz of two knitted woven fabrics, and when thermoplastic fibers are used, this is done to make the surface fuzz turn into fluff and make it less noticeable.

However, the method of the present invention rather involves making a sufficient amount of fuzz on the surface of a woven fabric, knitted fabric, non-woven fabric, etc., and then burning the surface to create a group of fuzz, which is different from the conventional hair burning method. have completely different meanings.

As for the method of firing, one side is cut and raised, and the raised side is fired.9 One side is cut and raised, and the raised side is fired.9
Method 9: Raising the reverse side with a loop It is also possible to create a striped pattern in the areas where the hair cannot be burnt to create a partial anti-slip effect.

The conditions for the above-mentioned hair burning process are as follows.

There are the pressure of the combustion gas, the distance between the flame and the fabric, the angle of the flame hitting the fabric, the speed of the fabric, the number of times the fabric is passed, etc., and these conditions must be selected depending on the fabric and purpose.

For example, in the case of Sunjet type manufactured by Shandong Iron Works.

The pressure of combustion gas can be varied from 80AQ to 230AQ, which represents the ratio of combustion gas to air.
The larger the AQ value, the stronger the condition. The distance between the flame and the fabric is varied from about 10 Crn to about 30 Crn, and the larger the distance, the weaker the flame. The angle of the flame hitting the fabric can vary from 30° to 90°, and the larger the angle, the stronger it is. The cloth speed can be varied from 50 m/mm to about 150 ml, and the faster the cloth speed, the weaker the effect. Also, the greater the number of times 9 passes, the stronger the condition becomes.

The fluff of this fluffed fabric is thermoplastic fiber.

Since the melting point differs depending on the fiber composition, the burning conditions must be adjusted accordingly.

For example, in the case of cut and raised warp knitted suede with a single denier of 1 denier made of polyester fiber with a relatively high melting point, the combustion gas pressure is 120AQ, the distance between the flame and the fabric is 15m, and the angle of the flame hitting the fabric is 90. By carrying out the process at a cloth speed of 60 mlmln and passing the cloth 3 times, it was possible to produce cloth A with good pilling.

In addition, a loop-raised base fabric of a warp-knitted suede structure of polyester long fibers was prepared and designated as Fabric B.

These A cloth and B cloth were able to obtain a very good sliding effect.

The state of the pill clusters obtained by burning the cut and raised surface of cloth A is that the pill clusters and forms a lump, and these pill clusters and lumps engage with the loop-raised base fabric, and are used for the one-sided fastener. It's not a hook-shaped or a dowel-shaped hook (the structure is completely different).

Figures 1, 2, and 3 show Sasago microphotographs of the shape of the fibers forming the pill group.

Figure 1 is an electron micrograph of the surface of a cut-raised base fabric of warp knitted suede fabric using polyester 75 denier/72 filament on the front, processed under the above-mentioned firing conditions, and is magnified at a magnification of 100 times. . Figure 2 is the same material as Figure 1, magnified 260 times, and Figure 3 is the same material as Figure 1, magnified 880 times.
It has been enlarged twice. Figure 4 is an electron micrograph of a 2-denier short polyester fiber web sandwiched between both sides of polyester tricot and laminated into a single sheet using the needle punch method after burning, and the shape of the fiber is magnified 100 times. . Fig. 7 is an electron micrograph magnified at 130 times of the fluffed surface of polyester spun voile yarn made of 1-denier polyester staple fibers used for the warp and weft. Observing these electron micrographs, the processing method of the present invention is the first.
．． Second. As shown in the electron micrograph of Fig. 3, this is different from the normal state of lint that makes the fluff less noticeable as shown in Fig. 7. It is clear that this is the processing method used.

The electron micrographs of cloth B corresponding to the electron microscope photographs of cloth A with 9 or more are shown in Figures 5 and 6.
The figure is an electron micrograph of the post-sintering electron micrograph shown in FIG. 4 before the sintering, and shows a large number of intertwined loops, with which the fuzz groups of fabric A engage. Figure 6 shows polyester 50
This is an electron micrograph of the loop-raised surface of a warp knitted suede structure using denier/24 filament on the front, magnified 44 times. As you can see in the photo, the roof loop is very visible, and the A fabric engages with this loop. It can be considered that the present invention can sufficiently exhibit the anti-slip effect by a combination of these.

(Applications of the Invention) Regarding these uses, the method for attaching cloth A and cloth B to products is that they have the same flexibility and texture as ordinary clothing, so they can be made into the size necessary for use. It can be cut and sewn by sewing. For disposable purposes or when the product cannot be sewn, use adhesive double-sided tape.

It is also possible to apply an adhesive to the back side in advance and affix a release paper, and then peel off the release paper before use and attach it to the product.

The anti-slip base fabric of the present invention is essentially a fabric used for clothing, such as knitted fabrics, non-woven fabrics, flocked fabrics, etc., so it has a good texture and flexibility and does not look strange no matter where it is used in clothing. Not at all.

(b) An example of something that is used over a large area is a belly wrap. This item has one side completely burnt and has a fluff loop on the back, so just wrap it around your abdomen and it will stay securely in place.

The fluff on the lining also has a great heat retention effect.

If you use a non-woven fabric manufactured by the needle punch method and have one side completely fluffed, and use it as a pillowcase and overlap the two ends under the pillow, the fluffed part and the fluffed part will overlap. The anti-slip effect prevents it from slipping. It is also possible to partially sinter only the part where the two pieces meet. It is hygienic and can be used for hotel guests and disposable after use.

(b) When using a wool-like base fabric made of short fiber fabric as the upholstery fabric, use a non-woven fabric with one side completely woolen and use it with the head cloth, so that the woolen side will engage the upholstery fabric. It never slips. When using a partially burnt cloth as a head cloth, burn the hair on the folded back part of the part where the head rests so that it will not shift even if a force is applied to the part where the head rests. On the other hand, you can use a material that has been completely woolen on one side as the outer fabric of the upholstery, but only on the area where the head rests. You can use it as a head cloth without it falling off.

(c) An example of using it as a part in a small area.

To prevent the menstrual belt from slipping, use cloth B, which has a pile structure, on the entire pant side or partially, and attach cloth A, which is non-woven and has a woolen surface on one side, to the pad side surface to prevent it from slipping. do not have. It is cheap and disposable, the pile structure on the side of the pants has a good texture and good heat retention, and has the advantage that it does not get dirty and requires less effort than conventional adhesive tapes.

(e) When used as a belt to be worn under clothing.

Either attach cloth A, which has one side of the entire surface of the fabric, with a pile texture or loop-raised product on the back side, or use a satin texture on both sides from the beginning. Ba.

The front side has A fabric and the back side B fabric, and if it is wrapped around the body as a flat string, it can be used as an obi without tying it.

This is a Y-shirt, if you put it on top of a blouse, it will be a Y-shirt
This will prevent the blouse from riding up.

(E) If the short ester fiber web is layered on both sides of the cotton knit and bonded using the needle punch method, only one side of the nonwoven fabric is completely fluffed to make fabric A.The back side has fluff from the double punch, and this is fabric B. Since it is made of cloth, if it is used as a bandage or supporter, it will not slip off even when wrapped around curved areas such as elbows, knees, wrists, etc., and has a dual-functional effect.

(f) Ester needle-punched non-woven fabrics, 9-knit ester woven fabrics, etc., all of which have been completely burnt.

By winding it around the surface of a metal roll and passing four knitted fabrics over it, the frictional resistance from the woolen fluff will prevent the fabric from sliding from side to side and causing wrinkles, and will also create tension in the fabric for appropriate resistance. Can be hung. Traditionally, rubber, cotton cloth, etc. with specially textured textures have been used for such applications, but since the resistance can be adjusted, the effect can be increased without damaging the fabric.

I have explained how to use 9 different methods above, but here is how to use them.

The uses are not limited to those described here.

All uses of cloth A processed by the method of the present invention are included.

(Examples and Effects) Example 1 A polyester long fiber semi-dull 75 denier/72 filament yarn is used for the front, a polyester long fiber semi-dull 30 denier/12 filament yarn is used for the knot, and a suede structure is created using a warp knitting machine. The knitted tricot A fabric was processed using a normal dyeing process. That is, the suede surface was napped four times using a cloth napping machine, shirred using a shearing machine to even out the fluff, and then scouring, dyeing, drying, and finishing setting were performed. Next, this raised surface was burned with the flame of a burning machine. The burning conditions were as described above, using a sun jet type manufactured by Dashi Tekko, combustion gas pressure 120AQ, distance between flame and fabric 15z, angle of flame hitting the fabric 909, cloth speed of 60 ml 1 m 1 p. It was a method.

The fabric A produced here had a knitted fabric with 54 wells and a length of 72.54 cm, and a knitted fabric with 74 courses and a length of 72.54 cm.

B fabric is polyester long fiber semi-dull, 50 denyl/24
Filament was used for the front, and polyester long fiber 20 denier/monofilament yarn was used for the thread, and knitted into a suede structure using a warp knitting machine. This knitted fabric was processed using a normal dyeing process. That is, it was scoured, clothed, treated with a softener, and then lightly raised using a cloth raising machine to the extent that the loops on the suede surface were drawn out, followed by dyeing and finishing.

When I pulled the two layers of fabric A and fabric B from side to side, it did not slip easily and had a very good anti-slip effect.

Example 2 A twill fabric was woven using nylon long fiber Bright 75 denier/36 filament yarn as the warp and nylon long fiber Bright 160 denier/72 filament yarn as the weft. After scouring and dyeing in the normal process, the cloth is raised using a needle cloth raising machine, shirred to even out the fluff using a shearing machine, and finished and set. Gomokugeyaki was performed at a speed of 80 m/mm. Note that other conditions were the same as in Example 1.

The finished longitudinal density was 118 lines/2.54 crn, and the latitudinal density was 95V2.54 cm. When the finished fabric A was layered with the fabric of Example 10B and stretched from side to side, a fabric with extremely high anti-slip effect was obtained.

Example 3 A web was made using semi-dull 2 denier polyester short fibers with a fiber length of 32+++m, and the web was layered on the front and back surfaces of cotton gauze woven with thread thickness No. 40, and this was layered using the needle punch method. A three-layered nonwoven fabric was created (also, the basis weight was approximately 100 g/rr?).

One side of this nonwoven fabric was heated at a cloth speed of 5 Q m/m using the above-mentioned wool burning machine.
It was passed through twice at ix to give it a fleece-sintering effect to obtain cloth A. The other conditions for hair burning were the same as in Example 1.

When the front and back surfaces of the nonwoven fabric were overlapped and pulled from side to side, a very good anti-slip effect was obtained.

Example 4 Nylon short fibers with a single yarn denier of 2 deniers and a cut length of 5 mm were electrostatically flocked onto a cotton broadcloth coated with a polyvinyl acetate adhesive resin. Fabric A was obtained by subjecting this flocked fabric to Asahiyaki once at a cloth speed of 80 m/+++jx using the above-mentioned wool sintering machine.

When the back side of the nonwoven fabric of Example 3 was layered as fabric B and pulled left and right, a fabric with good anti-slip effect was obtained.

Example 5 A web was made from short polyester fibers with a single yarn thickness of 3 denier and a fiber length of 64 mm, which was stacked in five layers, and an embossed pattern of polka dots with a diameter of 5 mm was crimped onto the web at 220°C. The nonwoven fabric produced was sanded to raise fluff, and passed through the fluffing machine once at a thickness of 60 ml and 1 mm to obtain cloth A.

Furthermore, when the back side of the nonwoven fabric obtained in Example 3 was superimposed on B fabric and pulled left and right, a fabric with good anti-slip effect was obtained.

As described above, it can be seen that the products described in the examples each have excellent anti-slip effects through the extremely simple operation of burning.
