Fire-protected double jacquard woven carpet

 

(57) Abstract:

Fire protective woven carpet for the soft coatings machinemade and belongs to the pile. The carpet is made in the form of indigenous base layer of cotton or globalassembly yarn. Flooring layer contains the basic thread of cotton or globalassembly yarn and the weft yarn from Logutov yarn. The pile is made of pure wool yarn or with the addition of modacrylic yarn at a ratio of 1:1. Pure wool yarn dyed chrome dyes in the amount of 1-1,5% of the weight of the yarn in the presence of dvuhromovokislyj or hexaferrite potassium in an amount of not less than 0.8% by weight of the yarn. The technical result is the expansion of the range of carpets with high performance properties. table 1.

The invention relates to soft coatings, carpet products machinemade, namely pile carpets.

Known layered carpet containing interconnected binder layer of the main Foundation with pile elements made from its front side, and a supporting base made of synthetic material, for example polypropylene (Patent Germany 3531489, And 47 G 27/04, 1986).

However, the known coatings do not provide the strength between layers and needed comfort.

The closest in technical essence is double jacquard woven rug, made in the form of indigenous foundations, flooring layer and the pile of pure wool, wool blend or synthetic yarn (GOST 28415-89 Coatings and products carpet woven machinemade". The official publication, Moscow).

However, the known carpet in its properties does not satisfy the consumer.

The objective of the invention is the creation of a fire-protected double jacquard woven carpet, which ensures the achievement of the technical result consists in increasing range of carpets and improve the operational properties by increasing the resistance to abrasion pile surface and biretrosteel.

This technical result is achieved by fire-protected double jacquard woven rug, made in the form of indigenous base layer of cotton or globalassembly yarn, flooring layer containing the main thread of hlopchato with the addition of modacrylic yarn at a ratio of 1:1, and use pure wool yarn, dyed chrome dyes in the amount of 1-1,5% of the weight of the yarn in the presence of dvuhromovokislyj or hexaferrite potassium in an amount of not less than 0.8% by weight of the yarn.

The claimed combination of features allows you to create a new fire-protected double jacquard woven carpet, which ensures the achievement of a technical result. Going beyond the proposed limits and the use of other yarns cannot provide high performance properties.

In the main core layer using, for example, cotton yarn with a linear density of 50 Tex X3 ( h) or globalview yarn with a linear density of 50 Tex X3.

In the flooring layer using, for example, as the main thread cotton yarn with a linear density of 50 Tex X7 ( h) or globalview yarn with a linear density of 60 Tex X7 ( 16,7x7), and as weft threads - locutory yarn with resultant linear density 280 Tex x2 ( 3,h).

The pile of a carpet made of fire-protected, dyed pure wool yarn, for example of the hardware pure wool yarn with a linear density of 220 Tex x2 ( 4,5x2) or 167 Tex x2 ( 6x2), painted the chrome cruciate not less than 0.8% by weight of the yarn or of a mixture of fire-protected, dyed pure wool yarn of 167 dtex x2 ( 6x2) and modacrylic yarn of 167 dtex x2 ( 6x2) with a ratio of 1:1.

To obtain a fire-protected and painted properties can be treated as pure wool yarn and wool fiber.

Get fire protective carpet is produced on a jacquard weaving machine, and then produce cut pile and finish it lead to the finishing line.

The invention is characterized by the following specific examples.

Example 1.

Fire-protected double jacquard woven carpet width 1400 mm made in the form of indigenous base layer of cotton yarn with a linear density of 50 Tex X3 ( h); flooring layer, the main thread which contain cotton yarn with a linear density of 50 Tex X7 ( h), and the weft yarn from Logutov yarn with a linear density of 280 Tex x2 ( 3,5x2), and a pile of hardware pure wool yarn with a linear density of 167 Tex x2 ( 6x2), which painted chrome dyes in quantities of 1% by weight of the yarn, in the presence of 0.9% dobromislova potassium from the weight of the yarn.

Example 2.

Fire-protected double jacquard woven carpet, width 1400 mm, made in the form of indigenous primary contain cotton yarn with a linear density of 50 Tex X7 ( h), and the weft yarn from Logutov yarn with a linear density of 280 Tex x2 ( 3,5x2), and a pile of hardware pure wool yarn with a linear density of 167 Tex x2 ( 6x2), painted chrome dyes - chrome yellow and chrome To dark green in the amount of 1.5% of the weight of the yarn in the presence of 1.25% hexaferrite and modacrylic yarn of 167 dtex x2 ( 6x2) with a ratio of 1:1.

Example 3.

Fire-protected double jacquard woven carpet, width 1400 mm, made in the form of indigenous base layer of cotton yarn with a linear density of 50 Tex X3 ( h); flooring layer, the main thread which contain globalview yarn with a linear density of 60 Tex X7 ( 16,7x7), and the weft yarn from Logutov yarn with a linear density of 280 Tex x2 ( 3,5x2), and a pile of hardware pure wool yarn with a linear density of 167 Tex x2 ( 6x2), which painted chrome dyes - chrome blue 2K in the amount of 1.5% of the weight of the yarn in the presence of 0.8% dobromislova potassium.

Example 4.

Fire-protected double jacquard woven carpet width 1400 mm made in the form of indigenous base layer of globalassembly yarn with a linear density of 60 Tex X7 ( 16,7x7); flooring layer, the main thread which soderjatel 280 Tex x2 ( 3,5x2), and the pile of hardware pure wool yarn with a linear density of 167 Tex x2 ( 6x2), which painted chrome dyes - chrome 2K blue and chrome yellow in the amount of 1% by weight of the yarn, in the presence of 0.9% dobromislova potassium from the weight of the yarn.

Specific parameters and technical characteristics of the proposed carpet in examples 1-4 are shown in table.

As can be seen from the table, stated fire protective carpet in comparison with the known carpet according to GOST has abrasion resistance of the pile surface, equal to more than 8000 cycles instead of 3000 cycles, increased resistance to biretrosteel, has a low surface Flammability J 12-15; and on other indicators meet state standards.

Developed fire-protected double jacquard woven carpet has high performance, is a new product that extends the range of woven carpets, which are recommended for interior decoration of ships, ship unrestricted navigation area, for railroad cars, as well as for hotels, offices and other facilities.

Fire-protected double jacquard woven rug, made in the form of indigenous base layer of the clap is whether globalassembly yarn and the weft yarn from Logutov yarn, and the pile of wool yarn or with the addition of modacrylic yarn at a ratio of 1:1, and use pure wool yarn, dyed chrome dyes, in the amount of 1-1,5% of the weight of the yarn in the presence of dvuhromovokislyj or hexa-porcelanato potassium in an amount of not less than 0.8% by weight of the yarn.
