Description

1 WOVEN LAMINATED THERMAL INSULATION

The technical solution relates to the textile industry, in particular, to the production of non-woven material made of fiber, made from several layers of synthetic fibers bonded together and used primarily as insulation in clothes and shoes, sleeping bags and tents, quilted blankets, as well as upholstery fillers, etc. P. products.

Known non-woven bulk heat-insulating material adopted for the prototype, which contains a fibrous mixture of several varieties of synthetic fibers, including low-melting, bonded with partially melted polymer of the latter (patent RU No. 2136794 class IPC D 04 N 1/44, 1999).

However, the manufacturing technology of such a well-known non-woven bulk material is quite complex and expensive, the resulting material does not have sufficient strength and good thermal insulation properties, and products from it have sufficient comfort.

The technical result of the claimed nolose model is the creation of a new non-woven layered chamfering material with increased strength, flexibility and good heat-insulating and electrically conductive properties, as well as a relatively easy manufacturing method.

This problem is solved in that the non-woven laminated insulating material contains a fibrous mixture of several varieties of fibers bonded to each other. At the same time, the material is multilayered, the canvases contain a mixture of natural fibers and synthetic fibers, a metallized film is located between the two canvases, and the layers are bonded to it by applying multiple finely non-perforated 1x holes with a needle punching machine.

MATERIAL

at least one layer is made of mesh material. As a specific embodiment, the mesh layer may be made of polyester tows located in the longitudinal or transverse directions. The mesh material may be located on the inside of the canvas of fibrous material. The mesh material may be located outside of the canvas of the fibrous material

The essence of the utility model is illustrated in the drawing, which shows:

figure 1 is a cross-sectional diagram of a non-woven laminated heat-insulating material with a metallized film between two canvases;

figure 2 is a micrograph of the surface of a metallized film;

Fig. 3 is a top view of Fig. 1, a micrograph of a non-woven laminated heat-insulating material with a mesh material on the outside.

The proposed non-woven laminated heat-insulating material consists of an upper canvas 1 and a lower canvas 2 containing a mixture of natural and synthetic fibers, as well as a metallized film 3 located between them. A layer 5 of mesh material is located on the surface of the outer canvas 1. This layer is made of mylar tows located in the longitudinal or transverse directions. It serves to increase the strength of the material. This layer of mesh material can also be located on the inside of the canvas.

All material is penetrated by through perforations 4 obtained by needle-punched machine. They play a two-fold role: they provide comfort to products made from such a fabric, since they allow them to “breathe and save them from the“ greenhouse effect in the presence of a metallized film located between the canvases, and on the other hand serve to bond the layers of material, since there are many small holes 4 technologically made needle-punched a machine, the needles of which, passing through all layers of the material, drag individual fibers behind them, which serve as a fastening element of the layers of the proposed material. The diameter of the perforation holes 4 is selected in the range of 0.08-0.3 mm, and their number is 8-20 pcs per 1 square. cm area of material. These parameters are selected both by calculation and empirically. Laboratory tests of prototypes of the material showed that these sizes of perforations and their quantity provide the material with the necessary strength and heat insulation properties, and products made from it have increased comfort. Metallized film 3 is made of aluminized lavsan film.

The proposed material is more flexible and has increased strength compared to the prototype, and products from such a fabric have improved thermal insulation properties and increased comfort in use. Applicant Author: -. . : f /// j I / / f. Yu.I. Borisov G4. . /
