Description

The present invention relates to multilayer and layered materials and polymer layers used in them.

In particular, the present invention relates to a multilayer material, in which one of the layers is polyester urethane, and is aimed at creating a polymer-textile multilayer material for a garment industry, mainly an outerwear.

From the prior art according to RU No. 2004167, IPC 5 A41 / D 27/06, 1993, a composite material for a clothing top is known comprising fabric upper material, a non-woven pad, bulk insulation material that is bonded to each other with an adhesive in the form of an aqueous polymer dispersion.

From the prior art according to RU No. 2004169, IPC 5 A41 / D 31/02, 1993, a multilayer material consisting of at least three layers is known:

external, intermediate and internal, of which the outer layer is the fabric for the top of the product, the inner is the volume insulation, the intermediate is the layer of adhesive material.

From the prior art according to RU No. 2004164, IPC 5 A41 / D 3/00, 1993, there is a known method of manufacturing heat-protective clothing, including the selection of top fabric, volume insulation, applying a layer of adhesive based on polymers to one of the materials, forming a package and joining materials among themselves at temperature and pressure, cut into parts and picking up a garment industry product.

The above technical solutions are characterized by the great complexity of the preparatory operations for sewing outerwear, which consists in the need for lengthy processes of selecting textile material for the outer and inner layers, as well as cutting parts separately for each of the layers, then combining the contours of the parts and additional fastening of the details of the cut into a bag using adhesive materials.

From the prior art according to RU No. 2004168, IPC 5 A41 / D 31/02, 1993 (the closest analogue), a method for manufacturing a two-sided garment is known, in which a three-layer composite material comprising the outer, inner and intermediate layers is used as a bilateral material, the outer and inner layers are fabric with a stiffness of not more than 30 · 10 ³ μN · cm ² , and emucryl M in the amount of 60 ml / m ^{2 is} used as an intermediate layer, while the final stiffness of the composite material is not more than 700 · 10 ³ μN · cm ² , and t thickness not more than 3.0 mm.

This method is also very labor intensive, consisting in the need to form a bag of external and internal tissues, subsequent gluing of the tissues at a pressure of 20 kPa and a temperature of 180 ° C, and checking the rigidity of the obtained composite material. Only after all these operations, the details of the future garment are cut.

The technical result of the invention consists in the creation of a polymer-textile multilayer material with optimal cost due to the energy-saving and less labor-intensive technology of its processing, while expanding the assortment of outerwear and improving working conditions when sewing it.

This technical result is achieved in the invention due to the fact that in a polymer-textile multilayer material comprising three layers: an upper layer comprising a textile web, an intermediate adhesive layer and a lower textile web, the upper layer is a bicomponent material comprising a front fabric coated on its wrong side with porous polyester urethane at a mass ratio of facial tissue and porous polyether urethane equal to 41 ÷ 73: 27 ÷ 59, respectively, has a thickness of 250-600 μm, stiffness based ve 520-800 μN · cm ² , the intermediate adhesive layer is made of thermoplastic with a melting point of 102-129 ° C, weighing 15 ÷ 20 g / m, and the lower textile layer contains a nylon knitted fabric with a surface density of 50-70 g / m ² , with the final indicators of the polymer-textile multilayer material: thickness 460-820 microns; stiffness on the basis of 3500-9000 μN · cm ² , while the polymer-textile multilayer material is presented in roll form.

In this case, the facial tissue in the material can be made of twill, contain polyester fibers or a mixture of viscose and polyester fibers in a ratio of 33:67 or a mixture of cotton and polyester fibers in a ratio of 51:49, impregnated with a water-repellent composition with a surface density of 110-230 g / m ² .

Moreover, in the material, the porous polyether urethane can be obtained from a composition based on polyester urethane, including 100 parts by weight polymer nonionic surfactant in an amount of 2.0-3.2 wt.h. cellulose filler in an amount of 25.0-40.0 parts by weight and N, N-dimethylformamide in an amount of 500.0-600.0 parts by weight

Another object of the invention is a garment industry product made of a polymer-textile multilayer material.

The composition of the polymer-textile multilayer material allows you to include in the composition of the upper layer of the front fabric of different coloristic designs, different prints, including camouflage, pattern and different texture, which allows you to expand the range of clothing items. The use of coiled multilayer material guarantees high precision cutting of a part in which the bicomponent top layer and the textile lower layer are present as a whole, reducing cutting time, eliminating shedding of cuts and delamination during sewing, which helps to improve the quality of the garment, and the optimal material thickness allows you to use existing sewing machines.

Also, the composition of the multilayer material guarantees the circulation (mass) production of an item of outerwear of the same size due to the cut of the parts of the product from a package composed of at least three layers of material.

The formation of a polymer-textile multilayer material is carried out by sequential technological operations: a bicomponent top layer is obtained by applying a composition based on a solution of polyester urethane, including a hydrophilic filler, nonionic surfactant, N, N-dimethylformamide, onto the wrong side of the front tissue, followed by immersion of the material in a coagulation bath, with the formation of a porous polyether urethane, washing in water, drying and reeling.

Then, after exposure of the obtained bicomponent material under static conditions for 48 hours, during which stress relaxation processes take place after drying, an intermediate adhesive layer of powdered thermoplastic is applied to the porous polyester urethane, similar to the prior art according to RU 2312571 C2, 2007.

Application of an intermediate adhesive layer is carried out on a special industrial installation. Thermoplastic powder from the hopper through the dispenser is uniformly applied to the surface of the porous polyester urethane of the moving bicomponent top layer. Thermoplastic powder particles are melted when the material passes through the heat chamber, and then on the flatting two-roll calender the molten thermoplastic particles are laid on a nylon knitted fabric and, passing through the gap, the material is compressed, the thermoplastic particles are flattened and rolled, while gluing (duplicating) the bicomponent upper layer. The intermediate adhesive layer is a system of randomly arranged flattened particles of thermoplastic powder, which provides the maximum possible area for bonding the upper layer with the lower layer of the multilayer material. Then the resulting material passes through a cooling calender and wound into a roll.

Polymer-textile multilayer material is presented in roll form.
