Description

The invention relates to multilayer needle-punched non-woven textile materials and the technology for their manufacture, in particular to the designs of artistic and decorative non-woven materials.

Known non-woven material containing layers of flat products bonded with a pile obtained from warp and weft threads, and with pile sections randomly placed on the surface of the material (RF patent No. 2170672, 2000).

The disadvantage of this material is the limited assortment capabilities and insufficient material strength. The material uses a small arsenal of technical and fine arts and crafts. The destruction of the warp and weft yarns to produce a pile and the chaotic bonding of the layers gives insufficient and uneven strength to the non-woven material.

The objective of the invention is to remedy these disadvantages, expand the assortment of non-woven materials and increase its strength.

The technical result is achieved in that the non-woven multilayer textile material contains at least two layers formed and heat-treated under pressure with compaction of the formed material by double-sided piercing with needles and turning the material, and one of the layers includes a continuous web of threads, and at least the second consists of an arbitrary number of flat and thread-like pieces of various sizes, stacked one on top of the other or placed one between the other, while on the outside Loops of filaments and fibers of layer components formed by immersing needles over the entire thickness of the material are formed on the material side.

The technical result is also achieved by the fact that the pieces are made of natural or artificial fibers, or various types of leather products, or mixtures thereof.

Fibrous pieces can be made woven, knitted or non-woven.

In addition, the pieces are partly flawed.

The invention is illustrated in the drawings and specific examples.

Figure 1 is a cross section of a multilayer needle-punched non-woven textile material according to the claimed invention.

Figure 2 is a front view of the material from the side of the combined layer.

Non-woven textile material in figure 1 consists of layers 1 and 2 of flat products. The number of layers may be greater depending on the designer's artistic design decision. Layer 1 is made of a flat continuous product in the form of fabric, knitted fabric, etc. from elastic strong threads. Layer 2 is assembled from an arbitrary amount of different size, shape and color of flat pieces 3. These pieces have a different shape from strict geometric to shapeless. In addition, the pieces can additionally be pulled to the state of tattered canvas. Such pieces may be in contact or located at some distance from each other. They are made of fabric, knitted fabrics, hand-made knitted and lace products, non-woven materials of any kind (punching, glue, stitching), carding canvas, films, leather, suede, fur. However, next to or on top of the pieces are laid pieces of long threadlike products 4 in the form of yarn, threads, cords, flagella, carding ribbons, rovings and the like. All this is bonded to each other and with a layer of 1 loops 5 of yarn and thread, making up a combination of 1-4.

The figure 2 shows an exemplary appearance of the combined surface of the described material.

The claimed material is prepared as follows. Layer 1 is laid out on the table. Moreover, depending on the designer's intention, it is displayed with folds and without them. Then, components 2-4 are laid on the resulting surface in accordance with the designer's intention. The obtained layered starting material is subjected to heat treatment under pressure. When this occurs, compaction and flattening of the material. Then the material is moved under the needles and punched with needle sections for the first time. The depth of immersion of the needles is chosen so that they, with their notches, grab yarn, threads and individual fibers and pull them through the material until loops form on the outside of the material. Then slightly bonded material is turned over and punched again with needles. The described process is repeated several times until the required consumer strength.

Since the flat product 1 consists of strong threads, the latter do not break off under the influence of the barbs of the needles 6, but are pulled out, forming loops above the outer side of the material. When this product 1 receives a slight deformation. All this leads to hardening of the bonding of the layers.

The following are examples of the implementation of the above materials.

Example 1. A multilayer needle-punched non-woven textile material contains two layers of flat products, one of which is made in the form of chiffon fabric with strong warp and weft threads. Another layer laid on the first consists of a combination of flat pieces of various sizes and shapes of fabric and knitted fabric. Fragments of a carding canvas are laid on these pieces. Pieces have a different color. The formed starting material is passed between the thermal baths and then punched with needles. The threads pierced by the notches of the needles form loops fastening the layers on the outer surface.

Example 2. The multilayer needle-punched non-woven textile material contains two layers of flat products, one of which is made in the form of chiffon fabric, folded. Another layer laid on the first consists of a combination of flat pieces of various sizes and shapes of fabric, knitted fabric, leather. Pieces of textile yarn are laid on said pieces and between them. The collected starting material is passed between the thermal baths and then punched with needles. Lightly bonded material is turned over and punched again with needles. The threads punched by the notches of the needles form loops fastening the layers on the outer surface of both sides.

Example 3. Multilayer needle-punched non-woven textile material contains two layers of flat products, one of which is made in the form of linen fabric. Another layer laid on the first consists of a combination of flat pieces of non-woven materials of artificial fibers of various sizes and shapes, a knitted fabric made of natural cotton fiber, suede, lace. Pieces of textile yarn from wool are laid on and between these pieces. The collected starting material is passed between the thermal baths and then punched with needles. Lightly bonded material is turned over and punched again with needles. The threads punched by the notches of the needles form loops fastening the layers on the outer surface of both sides.

Example 4. A multilayer needle-punched non-woven textile material contains two layers of flat products, one of which is made in the form of a synthetic mesh fabric. Another layer laid on the first consists of a combination of flat pieces of non-woven materials of artificial fibers of various sizes and shapes, a knitted fabric made of natural cotton fiber, and a synthetic film. Pieces of textile yarn from wool are laid on and between these pieces.

The formed starting material is compressed between heated flat surfaces and then punched with needles. Lightly bonded material is turned over and punched again with needles. Then the material is again turned over and punched again. The threads punched by the notches of the needles form loops fastening the layers on the outer surface of both sides.

Example 5. A multilayer needle-punched non-woven textile material contains two layers of flat products, one of which is made in the form of a knitted fabric of artificial threads. The other layer laid on the first one consists of a combination of flat pieces of various sizes and shapes, partially ragged to a tattered state, pieces of a non-woven fabric, a carded canvas made of woolen fibers, a knitted fabric made from natural cotton fiber, fabrics, and faux fur. Pieces of textile yarn made of viscose fiber and rovings were laid between the pieces. The formed starting material is passed between the thermal baths and then punched with needles on both sides. The threads punched by the notches of the needles form loops fastening the layers on the outer surface of both sides.

Punching was carried out on a needle-piercing machine IM 1800.

The heat treatment temperature and pressure were set each time based on the calculation so that damage and / or sintering of the components of the nonwoven material, for example, 30-150 ° C, did not occur.

The present invention can be implemented in an industrial environment on existing nonwovens without significant reconstruction and rearmament.
