Description

(54) CARPET PRODUCT

I

The invention relates to the manufacture of carpet products using synthetic wok materials on tufting or rashetti machines.

Physico-mechanical properties of carpets containing soil cloth with an emulsion coating and a pile loop layer tza textured rope tow (resistance

 to see, abrasion), are quite high. The use of synthetic materials causes high electrified carpet products, which creates a number of physiological and technical discomforts, as well as

their increased contamination.

Known carpet product of synthetic fibers, which has improved antistatic and soil protection properties achieved by treatment with water emulsion. However, surface treatment of carpet products with an emulsion contributes to a short-term improvement.

electrostatic and dirtproof properties, holding several chemical cleanings or washes.

The purpose of the invention is to improve the performance properties of carpets by increasing the conductivity and reducing the electrified.

The goal is achieved by the fact that polyamide yarns are used as the threads of the pile layer in the carpet product,

10 containing at least 2% of an organo-boron compound of polyethylene oxide, the width of the pile loop at the base does not exceed the distance between adjacent rows of loops, and the ratio

15 linear density of the pile thread and the height of the loops corresponds to the bulk density of the pile, which is not less than 0, O5 g / cmH

Emulsion coating g |) utovogo

The amount of charge accumulated on the product depends on the level of electrical conductivity and intensity of electropia. To make electrical conductivity it is necessary to reduce the electrical resistance of the components that make up the carpet product: the pile layer,

emulsion coating; however, the value of electrical resistance should decrease in the direction from the pile to the coating. This contributes to the discharge of electrical charges on the wrong side of the carpet. The intensity of carpet elimination due to I triboelectricity depends on the parameters of the pile layer, the linear density of the thread, the number of filaments, the size of the loop and the distance between the loops. Electricity decreases as the area of contact with the rubbing surface decreases. A uniformly distributed electric field and its dissipation can be achieved by creating a pile pile with a uniform loop structure: the width of the loop should be equal to or less than the distance between the rows of loops. It is stated and the fact that threads of different linear densities with a different amount of eepent {yah yarns can be used in a pile of carpets 1 in the carpet to drain off electrostatic charge $ 1 yes, the pile weight should be less than 0, 05: M

The use of textured polyamide filamentous filaments with 2-4% organo-boron compound of polyethylene oxide helps to reduce the focus on

The proposed carpet products are also of low contamination. This is due to a decrease in the sorption of aerosol dust and the relief of surface electrical resistance by 1–2 times 10–10 ohms. At the same time, the charge flows to the emulsion coating. To distribute and discharge the electrostatic charge from the pile layer, it is necessary to connect between each other the looped rows of an element with a conductivity no less than 1O times higher. This is achieved by applying a conductive emulsion coating. In the proposed longitudinal carpet product: the electrical resistance of the emulsion material should be no higher than 1O Ohm, and soot or carbanox should be introduced into the emulsion (non-ionic antistatic mixture of polyethylene glycol esters of synthetic fatty acids Q / 7 ° R®DI hydroxyethylation 20, TU 6-06 -32-179-78), or kaolin, or metal salts.

For the manufacture of such a carpet product, no additional operations or equipment are required, the invention may be implemented in the field of carpet plants.

The laboratory's evaluation of the electrophysical properties of carpet products manufactured according to the invention showed that, compared with the conventional (non-antistatic) carpet products used, they are significantly better indicators.

Indicators of electrophysical properties of carpet products are given in table. one.
