(57) Abstract:

The invention relates to the textile industry and can be used in flour milling, food processing, printing, electronic industry and for screen printing. The fabric contains basic and weft monofilament linear density from 1.3 to 103 Tex synthetic fibers. Types of regular holes are square, a rectangle with a size range of regular holes 26 to 1180 μm and a coefficient of screening from 20 to 60%. The fabric material is 30-150 g/m2. The fabric is produced of plain, twill, paulonis delicate weave of polyester, polyamide, polypropylene filaments. The number of threads per 1 cm in the warp and weft varies in the range from 6.5 to 180. This fabric is durable, versatile and universal in application, resistant to corrosion and microorganisms. 3 C.p. f-crystals, 1 table.

The invention relates to the textile industry and can be used in flour milling, food processing, printing, electronic industries and for screen printing.

Known technical sieve cloth, where the raw material used threads of natural silk cells, reduced tensile strength. They are not resistant to the action of microorganisms and are able to mould.

Known filter cloth for liquid media, made plain weaves the weft thread which are combined filament polyester yarn in two additions and polyamide yarns when the mixing ratio from 50:50 to 50:45 (SU # 1663070 A1, class D 03 D 15/00, 15.07.1991). This fabric is most similar to the invention of the technical nature.

However, it cannot be used as screens for solids, because it is made of plain weave and has no regular holes and is used only for filtering liquid media. In addition, the fabric has a very high intensity (surface density 440-540 g/m2), which causes inconvenience in use and require a considerable amount of raw material while manufacturing.

The technical result, which is aimed invention is to create a versatile fabric for filtering any fluid (bulk in a large range of dispersion, liquid, dispersion media, viscous systems, semi-fluid (blood, plasma), printing pastes, specially the result is achieved by in technical fabrics for sieves containing the main and the weft yarn of synthetic staple fibres, according to the invention, the main and weft yarns are monofilament of from 1.3 to 103 Tex.

The number of threads per 1 cm as the basis, and the duck is in the range from 6.5 to 180.

This species is a regular holes are square or rectangle with a range of sizes regular holes 26 to 1180 microns.

Factor screening (percent of square holes tissue, %), characterizing the filterability, changes in the proposed tissue from 20 to 60%. The surface density of the fabric is 30-150 g/m

The fabric is polyester, polyamide, polypropylene monofilaments plain, twill, paulonis openwork interlacing.

Products offered fabrics (mesh) allow filtering of solids in a wide range of dispersion of the particles is from 30 to 1000 μm.

Below are examples produced in accordance with the invention tissues.

Example 1. Technical cloth sieve, plain weave has a surface density of 133 g/m2. The fabric in the warp and weft are made of polyamide monofilament line is ucih substances with a particle size of 600 μm, water, blood, plasma, liquid media with a pH of 7.

When designing fabrics plain weave do not require winding and twisting and provides high performance weaving equipment, namely 10 Pogue. m/H. the Fabric is resistant to microorganisms and corrosion without special treatment. Physico-mechanical properties of the fabric shown in the table.

Example 2. Cloth sieves twill weave has a surface density of 40 g/m2. On the basis of and duck fabric made of polyester monofilament linear density of 1.7 dtex and is designed to filter and screen printed pastes, fine (up to 40 µm) of granular media, special chemical liquids with a pH of 5 to 6.5. If the development does not require operations of winding and twisting.

The fabric is resistant to corrosion and microorganisms without special treatment. Physico-mechanical properties of the fabric shown in the table.

Example 3. Cloth sieves popularnego open weave has a surface density of 47 g/m2. Fabric made of polypropylene monofilaments following linear densities of 3.3 dtex and 6,7 Tex. Cloth sieves according to the invention is intended for a filtration of bulk materials which supports the high stability of the frame, cells and durability of the fabric. If the development does not require operations of winding and twisting.

Example 4. Cloth sieve, plain weave weighing 28 g/m2. The fabric on the base is made of polyester monofilament linear density of 2.2 dtex, and the duck from polyamide yarn of the same linear density.

Cloth sieves, according to the invention, provides filtration of dispersions with different particle size greater than 10 microns, blood, plasma, printing pastes, liquids.

The fabric is characterized by high strength, ensures uniformity and stability of the cell, high efficiency.

The fabric is resistant to corrosion and impact of microorganisms without special treatment. Physico-mechanical properties of the fabric shown in the table.

Example 5. Technical fabric to sit twill weave has a surface density of 30 g/m2.

The fabric in the warp and weft are made of polyamide monofilament linear density of 1.3 Tex. The size of the holes 26 μm. The coefficient living section is 20%. Physico-mechanical properties of the fabric shown in the table.

Example 6. Technical fabric to sit linen perepleteniya linear density of 103 Tex. The size of the holes 1180 microns. The fabric is designed to filter solids with a particle size of 860 μm, liquid media pH 7. The coefficient living section is 60%. Physico-mechanical properties of the fabric shown in the table.
