Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a method for reinforcing a tungsten fiber section, preferably in the front part of a garment, in the form of a web or made of a web. interfacing material (or interfacing material) with elasticity that varies in direction
terial). Manufactured with such interpolated materials, the clothing is cured. Or the reinforcing interpolation may also be a multi-region interpolation.
facings), which are fixed to the parts of the garment to be reinforced by ironing or thinning.

[Prior Art and Problems to be Solved by the Invention] The above-mentioned interpolation material includes fibers of warp fibers in the form of a stitch with an additional standing end joined to a transverse web direction. Resilience changes in the direction, ! It includes a fibrous fleece connected to the Alt fibers and an additional standing end, and in some cases embedded between the Alt fibers and the standing ends, as described in German Open No. 2,332.492. however.

No practical use has yet been found. In this material, the standing ends are embedded in a straight line and covered by stitched warp threads.

Other interpolating materials are also known, consisting of fibers or woven fibers, and two different graded
zones or regions
, in which different warp threads are used from section to section, so that the fibrous web has a fibrous web with respect to its elasticity, from one edge to the center of the web or from the other edge of the web. Regionally sloped.

An interleaved blank is cut out in the transverse direction as illustrated in FIG.

A fundamental drawback of these known fiber or woven multi-region interpolations is that they have different elasticities intended for the knee, torso and shoulder areas of the front of the garment.
The problem lies in the inability to achieve the desired graded strength of elasticity between zones with y). The desired strength of the layer regions leads to very tight knee areas, especially for multi-region fabric intersperses.

If an attempt is made to create room in the knee area using thinner warp fibers in a more open arrangement, soluble adhesives may be used to adhere the inserts by ironing the surface sections of the garment. Problems arise with the rusk-like coating with objects, as after ironing the surface section of the garment, the adhesive soaks into the interpolation, as a result of which:
Clothing manufacturing will be impeded to an unacceptable degree.

Adhesion of the garment to the lining material occurs later. In some cases, this drawback is circumvented by the use of woven interpolations, but this does not achieve the desired concept in the clothing industry for grading in areas of one elasticity.

It has not been previously possible to achieve the desired high grading strength with woven fibers and at the same time create an interpolation material that is sufficiently resistant to shrinkage.

Although known woven multi-domain interpolations have good slope strength, they exhibit a tendency to shrink, particularly when washed, and to shrink horizontally. Reinforced standing ends buried in the direction often shift and form loops.

[Means for Solving the Problems and Two Effects] The present invention solves the problem of adhesion of molten adhesive without causing excessive shrinkage of the warp yarns, and subsequently solves the problem of adhesion of molten adhesive and the eye openings of surface sections or similar. It is an object of the present invention to provide an interpolation material graded with respect to elasticity, which does not cause problems with bending and has a high graded strength.

This object is achieved by the interpolation material of the invention mentioned at the outset, which interpolation material has an additional standing end bound therein and transverse to the web direction. Stitched warp fibers with different elasticities and connected fibers and additional standing ends. or includes a fibrous fabric embedded between the fibers and the standing end, the fibrous fabric is a spot-bonded fibrous fabric that does not depend on binding, and the spot-bonded fibrous fabric is made of synthetic fibers of 75X or more. It has a fibrous portion, and is characterized in that the standing ends are bound by horizontal floating yarns of stitch-like warp fibers bound to each other.

Surprisingly, in this method a high graded elastic strength is achieved without excessive shrinkage, especially without shrinkage in the warp direction. Furthermore, interpolations cut from such materials are provided without problems such as rusk-like deposition on one side for fixing the fibers, and can be removed from external materials or very easily without shrinkage. Can be separated from clothing with good adhesive properties.

Further developments of the invention will become apparent from the claims dependent on claim 1.

FIG. 2 shows a part of a first embodiment of an interpolation material according to the invention, which interpolation material has a tricot weave kXAMi (netwo

The figure shows a part of an interpolation material according to another embodiment of the invention, which interpolation material has complementary standing ends and is formed in stages in discrete areas a, b, c. It shows that FIG. 4 shows a section of an interpolation material according to a third embodiment of the invention, which interpolation material has standing ends of different restraints and is graded in one discrete area a, b, c. It shows that it is formed. FIG. 5 shows a portion of the interpolation material of the fourth embodiment of the present invention, showing that it is formed stepwise in one individual area a, b, c. FIG. 6 shows a portion of the interposer material of the invention, shown in a perspective view and in a connected state relative to one of the preceding structures. FIG. 7 shows a portion of a fifth embodiment of the interpolation material of the invention, showing two separate areas a.

It is shown that it is formed in stages in b and c.

In a relatively simple embodiment based on FIG.

The interpolation according to section 2a consists of a tricot weave 1 of warp fibers in the form of stitches, the stitches having stitch ridges (s
web direction in the form of 2 (titch wale) 2.

and are arranged in the horizontal direction in the form of stitch rows 3. The transverse floating threads 4 of the warp threads bind standing ends 8 of different inclined elasticity. The bound standing ends 8 are wound alternately from one side of the stitch ridge 2 to the other. Section 2b shows how the fleece 5 is embedded between the standing end 8 and the transverse floating thread 4 above the solid line and between the stitch ridge 2 below the broken line. Finally, section 2c shows a rusk-like coating 6 which can be applied to the upper and lower image areas.

In the sloping resilient formation, for example 9, only partially illustrated, extends downwardly from the top of FIG. A longitudinal line 11 oriented in the web direction in FIG.
The increase in density per area indicates an increase in elasticity from the edges to the center. In this illustration, line 12 shows two sections forming two multi-area interpolations for the front part of a lounge jacket or coat.

In the production of multi-region interposers, a region-by-region increase in elasticity can be achieved by varying the thickness of the fibers of the standing ends 8 of the standing end system.

In FIG. 1, for example, the thickness of the fibers at the standing ends can be very small, such that the thickness of the fibers at the standing ends is very thin <, for example 1.2 dtex, at the edges 10a, 10b of the web material 10, The thickness of the fiber at the standing end of the material center 10c is very thick, for example 100 dtex. It also reduces the standing end thickness.

By accenting (the fiber thickness is thinner at the edges and thicker in the center), grading is achieved, and finally,
This can also be reduced by changing the twist of the yarn, the fiber material and the chemical nature of the fibers of the standing ends 8.

According to another embodiment of the invention shown in FIG. 3, other standing ends are not placed around the stitch ridges 2 between the so-called short circuit standing ends 8 of FIG. It is possible to bind 9. According to section 3b of FIG. 3, these straight standing ends 9 are placed on the front side of the web material of the transverse floating thread 4, which is placed between two adjacent stitch threads. The fleece 5 buried behind these is fixed. In this case, a rusk-like coating 6 is provided on the front side of the web material to prevent the straight standing ends 9 from shifting.

A further embodiment according to FIG. 4 shows a variation of the restraint of the short-circuit standing end 8. The short circuit standing end 8 has stitch ridges 2,
It is then placed around each adjacent stitch ridge 2 and fixed by branching the lateral floating thread 4 in the lateral direction. The structure made by the sectioning of FIG. 4 with standing ends 8 and internally placed fleece 5 and the rusk-like coating 6 according to section C of FIG. It has a certain amount of elasticity in the longitudinal direction to ensure uniform shrinkage.

In this embodiment of the multi-area interpolation according to the invention, the rusk-like coating 6 can be arranged on both sides.

Similarly, in the embodiment of FIG. 5, which can be distantly related to the gradient of elasticity for each region in the same way as the interpolation of FIG. There is the possibility of embedding between 8 and also between standing ends 9, here between standing ends 8 as short-circuit standing ends.

Section C in FIG. 5 shows the manufactured structure with standing ends 8 and 9, and section C in FIG. 5 shows the coated formation. Since the restraint of the intermediate short-circuit standing end 9 is thinner than in the embodiment according to FIG.
Coating is on both sides. However, preferably the coating is on the short circuit standing end side.

Finally, there is also the possibility of combining different types of binding of the standing end 8 together. In another embodiment of the invention designed, for example, in the knee region of a garment insert, the method of binding the slightly twisted thin fiber standing ends 8 is based on the embodiment of FIG. On the other hand, for the torso region and layer region of clothing inserts, a binding method of standing ends 8 with larger twist and thicker fiber thickness is provided based on the embodiment of FIG. Ru. The thickness of the standing end 8 fibers used varies over a wide range, for example from 1 dtex to 3 Q dtex.
Fibers with a precise thickness are used mainly in various regions, and fibers with a coarse thickness are mainly used in layer regions. The twist thickness can be varied from 5Qdtex to 1500dtex, and staple fibers, endless fibers, and multifilament fibers are used. The fiber material is
Cotton, viscose staple fibers and two-dimensional fibers may also be used.

It is also possible to use wool or hair, and both are preferably treated with anti-felt. A ripple twist is also provided to make the torso area particularly soft. The twist is
Simple twists, double twists, or rolled twists can be used. Thus, for example, a very strong twist with very little capillary action is spun with a very precise twist.

The basic braid connecting the standing ends 8.9 and the fleece 5 together is constrained in different ways. On the other hand, let's talk about tricot weave.

For example, a combination of tricot and ground weave with ground weave or fringe weave is possible, the latter not itself forming a braid. Other types of weaving are also suitable.

The basic braided stitch ridge fiber 2 preferably consists of a synthetic multi-filament yarn, the yarn being 3Q
It has a thickness of dtex to 50 dtex.

It has a fiber thickness of 1 dtex to 4 dtex.

The fleece 5 consists of a spot-bonded fleece embedded in the basic braid, which is held independent of binder impregnations.

This spot-bonded fleece has a high proportion of synthetic fibers, such as polyester fibers or polyamide fibers, as high as approximately 75%, which are bonded under high pressure and temperature. In this regard, preferably.

A small fleece fiber thickness is chosen, the value of which is 0.
9dtex to 3. It is between 3dtex. Puncti form connections 6 are made in a regular arrangement or in an irregular arrangement (random point arrangement). The number of connecting spots is preferably in the range from 30 to 80 spots/cm2, and the proportion of the bonding surface of the total surface of the fleece 5 is between 4% and 10%, thereby providing an optimal composition suitable for the kneecap area. Bonding is usually done with a heated porcupine roller and a flat heated counter roller, the temperatures of which are slightly different and allow the fleece to become stronger while maintaining its softness. Close to temperature. The pressure surface of the rotating part is square, square or diamond shaped. FIG. 6 schematically illustrates a bonded fleece.

The invention also makes it possible to provide an interpolation material with waft yarns. To prevent shrinkage of such products, weft yarn material is used, 75 dte
x to 310 dtex in thickness and either have some or no synthetic fibers. For example, cotton or viscose stable fibers, and polyester fibers, acrylic yarns, and
Particularly suitable are synthetic stretch yarns, for example weft yarns of mixtures of pure polyester stretch yarns. The latter produces or has a stable and enhanced spreading elasticity in the weft direction.

In the embodiment of FIG. 7, weft fibers 13 extending transversely to the web direction are embedded behind the composite thread between the fleece 5 and the standing ends 8, 9.

Coating is accomplished with the multi-area interpolation material of the present invention with conventional hot melt adhesive materials.

The above-mentioned melt adhesive materials include screen printing (or printing) + gravure printing, covalent polyamide in the spray printing direction, polyester, etc. A combination of screen printing and spray printing is also possible with the so-called double coating method. Roller coating methods can likewise be carried out. The raster array can be either regular or irregular. The applied coating spots have a dot-like or rod-like shape. Preferably, however, a puncture foam coating is used. The number of coating spots is typically between 15 and 150 spots/cm''; the amount of application is between 12 and 25 g/cm''; No problems occur.

Instead of varying the elasticity across the cross-section of the web stepwise, it is also possible to maintain a continuous change in the elasticity.

The interpolation material according to the invention is suitable not only for reinforcing the front part or other parts of clothing, but also for reinforcing textiles in other applications, for example in the field of decoration.

〔Effect of the invention〕

As described above, according to the present invention, the interposer exhibits high strength and tapered elasticity without causing excessive shrinkage or problems such as adhesion of molten adhesive. Materials provided.
