Description

Technical field

The present invention, in General, relates to the development of an improved structure of non-slip material of Velcro fasteners, the features of which allow it to be used for mass production and provide a large width of the surface area, great flexibility, elasticity and light weight, as well as advantages such as high breathability and low production costs, the possibility of use in combination with other materials and connections with various woven / non-woven materials, flannel, loop woven anyu (terry cloth), to ensure quick fastening from a single touch of the finger and lack of slipping.

State of the art

Well-known Velcro fastener tapes or Velcro tapes (contact tapes) have such features as the ability to fasten with a single touch with a finger and the lack of sliding. A well-known pair of Velcro tapes often consists of an upper ribbon on which micro hooks are located, and a lower ribbon on which there are pile / loops. The upper tape with microhooks has a felt-like front side forming a surface on which a plurality of protruding microhooks are evenly located, the ends of which are rounded. The lower tape has a velvety front side forming the surface, on which curled, tangled yarn fibers are evenly located. When the upper and lower ribbons are superimposed on each other, the felt-like front side comes into contact with the velvety side, micro hooks hook on curled, tangled yarn fibers to ensure the ribbons are fixed to each other. The known structure of Velcro fastener tapes is effective for fixing fastened products, however, the manufacture of traditional Velcro tapes is associated with high production costs and difficulties in manufacturing large width tapes, and is suitable only for the continuous production of elongated tapes with a small surface area, which makes production indicators quite low . In addition, the traditional Velcro fastener tape, as a rule, does not bend well, which makes it difficult to connect it to products or materials with a three-dimensional configuration. To overcome these problems, the present invention proposes a unique velcro fastener material, which can be made by weaving synthetic fibers / yarns with different characteristics, or synthetic fibers / yarns of different diameters, to ensure compliance with the requirements of various applications, and in which the length used synthetic fibers / threads can be installed depending on the desired processing method. The threads are woven with the formation of a warp layer, which can be a fabric of a cellular structure with areas with empty (hollow) holes (see the attached drawings, Fig. 1) or fabric of a cellular structure in which there are no areas with empty holes (see Fig. 7 ) When the honeycomb fabric so woven has sections with empty openings, it is assumed that such sections with empty openings may be of various shapes, for example, in the form of a ring, honey honeycomb, square or other geometric shape.

The formation of areas with empty holes gives non-slip material properties such as higher tensile and deformation elasticity both in width and in length, as well as higher breathability. It also offers advantages such as higher forming capabilities for creating a three-dimensional configuration for bonding with surfaces of other materials that also have a three-dimensional configuration. Since the synthetic fibers / yarns in the warp layer are weaved together, all synthetic yarns adhere tightly to each other without undesired separation, and therefore, there is no need for an additional adhesive layer applied to its lower part to fix the fibers / yarns. This gives the material proposed in the present invention advantages in terms of production costs. The velcro fastener material of the present invention can also be further processed by passing it through a tunnel kiln in which the ends of the fibers / threads melt to form hooks with rounded ends. The velcro fastener material of the present invention has a high sliding resistance and, thus, finds the widest range of applications for anti-slip material in various industries.

Thus, the present invention is based on the task of creating a non-slip material for mass production, characterized by light weight, breathability, elastic expansion, and having a simple structure, which can provide effective sliding resistance when used with various materials, such as woven / non-woven products , flannelette, loop (terry) fabric.

Disclosure of invention

The main objective of the present invention is to create a material structure of the Velcro fastener that provides non-slip properties of the material made by the weaving method, due to which the non-slip material acquires flexibility and elasticity, and is formed by weaving two types of fibers / threads: fibers / threads from different materials with synthetic fibers / filaments to obtain a woven base layer comprising a large number of synthetic fibers / filaments expanding in this layer, and such non-slip Boxing material can be offered for mass production, and will be distinguished by such high qualities as light weight, breathability, elasticity and manufacturability.

Another objective of the present invention is to provide a non-slip material characterized by a high degree of elasticity and flexibility, which makes this material suitable for easy bonding to the surface of a volumetric configuration material so that such non-slip material easily assumes the desired shape to obtain the desired surface adhesion to the volumetric configuration material .

Another objective of the present invention is to provide a non-slip velcro fastener material used with materials such as woven / non-woven materials, flannel, loop fabric (terry cloth) to prevent slipping.

To solve the above problems, the present invention provides a non-slip velcro fastener material, which is a woven warp layer with many synthetic fibers / threads woven together and connected to each other in the warp layer. A woven warp layer is obtained by interlacing two flexible (soft) strands consisting of warp threads and synthetic threads, while allowing synthetic threads to extend beyond the woven warp layer to a predetermined distance. Synthetic threads have a predetermined hard resistance to deformation (inelasticity / rigidity), and the warp layer on the back side gets weave, which is flexible, elastic and lightweight, due to which when attached to woven / non-woven materials, flannel, loop fabric (terry cloth) non-slip The material of the present invention provides high slip resistance.

The above objectives and a summary of the invention only briefly reveal the concepts of the present invention. For a more complete understanding of the above and other objectives of the present invention, as well as the invention itself, a detailed description of the invention is set forth below, which should be read in conjunction with the accompanying drawings.

The implementation of the invention

The following description represents only preferred embodiments of the present invention and, in no way, limits its features and applications. In other words, the following description is a convenient illustration of embodiments of the present invention. When determining the function and location of the described elements, the aforementioned embodiments of the present invention may be amended without departing from the scope of the invention defined in the attached claims.

Below, the present invention is described in more detail with reference to FIGS. 1, 1A, and 2, in which FIG. 1 is a perspective view of a non-slip velcro fastener material of the present invention, FIG. 1A is an enlarged view of a portion of a non-slip velcro fastener material, and FIG. 2 is a schematic drawing of a warp layer woven together with synthetic fibers in accordance with the present invention. As shown in the aforementioned drawings, the non-slip velcro fastener material of the present invention, having a common digital designation 10, consists of a plurality of synthetic threads 20a, 20b and flexible warp threads 30a, 30b.

Figure 3-5 shows how each synthetic thread 20a, 20b is bent to obtain a U-shape, including a loop 21 (see figure 3) and two protruding outward short legs 22 (see figure 3). Each back loop 21 goes around each front loop 21, so that both loops 21 are connected together to form short legs 22 that are located at the ends of the loops 21 and have a predetermined length by which they extend beyond the base layer 40. The flexible warp yarns 30a, 30b go together with the synthetic yarns 20a, 20b, alternating in a front-to-back direction (see FIGS. 3 and 4), so that the first synthetic yarn 20a is connected to the yarn 30a of the warp layer, while the second the synthetic thread 20a, which is looped to the first synthetic thread 20a, is connected to the thread 30b of the warp layer. Similarly, the first synthetic thread 20b is connected to the warp thread 30b, while the second synthetic thread 20b, which is looped to the first synthetic thread 20b, is connected to the warp thread 30a. By this method, two weaving weaves are obtained together using two threads (woven together in a two-thread manner), with the formation of a woven weave A (as shown in FIG. 1A). Synthetic yarns 20a, 20b and warp yarns 30a, 30b are woven together in a single horizontal plane to form a warp layer 40. The warp yarns 30a, 30b are arranged so that they run parallel with the synthetic yarns 20a, 20b, and so that the warp yarns 30a, 30b, after bending together with the synthetic yarns to form loops 21, are able to stretch in the transverse direction, each individually , and then go in parallel with the synthetic threads 20a, 20b of the adjacent weave (see figures 3 and 4). Synthetic yarns 20a, 20b can be made of polyamide or polyesters, or polypropylene (PP), or polyethylene (PE).

As shown in FIGS. 3-6, the warp yarn 30a, arranged so as to go together with the synthetic yarn 20a to form a loop, has the ability to stretch in the transverse direction to the adjacent weave yarn 20b, for subsequent joint stretching together with the synthetic yarn 20b for weaving in two threads so that the synthetic warp threads 20a, 20b and warp threads 30a, 30b are interlaced in one horizontal plane to form a warp layer 40. The fabric of the warp layer includes loops 21 of synthetic threads 20a, 20b, connected to each other in the front-back direction, so that the back of the loops covers the front loop and each of the connected loops 21 has ends that form short legs 22 of a given length that extend beyond the layer 40 the basics. When the warp yarns extending in the transverse direction are long, the length of the warp yarns allows the formation of spaces X that define hollow holes, whereby the warp layer 40 has sections with empty holes that can be of any desired shape, such as a honey ring honeycomb, square and other geometric shapes. The presence of sections with empty holes allows to increase the elasticity and the ability to deformation in both longitudinal and transverse directions.

As shown in FIG. 7, the present invention provides a non-slip velcro fastener material 10a which consists of a large surface fabric weaving the warp layer 40 to cover a large area, while warp threads 30a and 30b interwoven in the warp layer for stretching in the transverse direction in the plane of the fabric, they are located very closely relative to each other, so that the too long lengths of the warp threads 30a, 30b do not form spaces X that define the formation of hollow holes. And in this way, the non-slip fastener material 10a of the velcro planar structure is obtained.

Next, with reference to FIGS. 8 and 9, another feature of the present invention is disclosed, according to which the velcro fastener material of the present invention, after weaving the synthetic threads 20a, 20b together with the warp threads 30a, 30b, is further processed by passing through a tunnel furnace for heating as a result of which the free ends of the legs 22 of each synthetic thread 20a, 20b are fused to form rounded ends 23 (see Fig. 8). According to another method, the free ends of the legs of each synthetic thread 20a, 20b are heated and compressed to form hooks 24 (see FIG. 9). The short legs 22 of the synthetic yarns extending beyond the surface of the weaving fabric extend beyond the warp layer and the distance or length of the legs 22 of the synthetic yarns 20a, 20b can be adjusted as desired and the synthetic yarns exhibit a certain stiffness.

Thus, the non-slip material of the Velcro fastener according to the present invention has several advantages, namely: light weight, high breathability and flexibility, which allows it to be used for mass production of large width materials.

To summarize the above, the present invention provides a non-slip velcro fastener material, the structure of which includes short synthetic fibers woven together with the fabric of the fabric forming the warp layer to prevent slipping when bonded to woven / non-woven materials, flannel and loop fabric (terry cloth ) In addition, when weaving, the synthetic yarns are very close to each other so that, when unfastened, the synthetic yarns do not tear out the yarns / velvety material of which woven / non-woven materials, flannel and loop fabric (terry cloth) are made, and thus, said yarn / velvety material was not damaged. Material of the present invention: easily connects at the touch of a finger and exhibits higher slip resistance.

Although specific improved features of the implementation of the present invention have been illustrated, described in detail and listed, they should not be construed as limiting the present invention to such features of its implementation, as it will be apparent to those skilled in the art that various modifications, additions, changes, etc. can be made. D., without departure from the essence of this invention.
