Description

Antistatic carpet or antistatic Texspiohbahn

The invention relates to an antistatic carpet or an antistatic carpet web, in particular those consist of a fiber layer, an antistatic conductive layer and a polymeric backing layer.

The conventional carpets are capable of static electricity to generate and to. transfer. Static electricity is generated when people in contact with the dielectric fiber layer of the carpet move across the fiber layer. The charging is caused by the movement of the dielectric components of the shoe, which are in contact with the dielectric fiber layer. The "charge will" then be transferred to the carrier

Transfer shoes. If the carrier is later earthed, The accumulated charge is discharged through the part of the human body that is in contact with the point of release is. The discharge procedure can cause great discomfort evoke for the individual. The problem described above can be eliminated if the static electricity dispersed through the carpet structure and can later escape into the air.

The known carpets contain a plurality of antistatic compounds and an antistatic carpet structure. In which is described in U.S. Patent 2,302,003 to CadweIl described an antistatic carpet structure in which the accumulated charge is passed through a variety of conductive Fibers attached within the fiber layer,. be dispersed. In contrast, the carpet structure of the present invention disperses the static electricity quickly and carefully, without using special conductive leads. The carpet structure of the present invention conducts static electricity through a critical. conductive layer. The continuously conductive layer the carpet structure must be such that it can disperse and dissipate static electricity. On the other hand, the antistatic layer must not be so strong that it interferes with the aesthetic appearance of the carpet.

The antistatic carpet structure of the present invention contains a polymer backing. Most of the well-known anti-static compositions come with the polymeric back layer not compatible .. Because of "this Carpets that have been treated with the known antistatic compounds cannot deal with incompatibility most polymeric backing layers and especially not with the usual natural rubber backing layers be equipped. In contrast, the inventive antistatic "coating compositions with natural rubber backing layers and with most compatible with other polymeric coating materials. Therefore may be the case with the antistatic carpet structure * - a rubber backing layer can be applied to the invention

15 den.

The essential antistatic carpet structure is illustrated in FIG. The carpet structure 2 has a conventional one Fiber layer 4, which is woven, tufted, knitted or flocked or other structures customary for carpets

bindings or polyester. The fiber layer 4 is woven in, tufted or in any other way on the Back layer 5 attached; usually woven fibers of cotton or jute can be used for the backing although other fibers and types of construction are possible. The basic structure of the carpet can be any carpet brand, such as the well-known Tufted, Brussels, Wilton, Axminster, Chenille, Velvet flakes, knit. According to the present invention is the underside of the fiber or stack layer 4 and the first back layer 5, which is attached to the fiber stack or through which this is tufted, etc., are covered with an antistatic coating 6, the one uniform layer and the back layer and

The antistatic coating composition used to produce the antistatic coating layer 6 consists in essentially from a mixture of an antistatic textile ■■ means and a humectant in the ratio of 4 to 8 parts by weight of antistatic agent and 10 to 50 parts by weight of humectant. Advantageously it also contains 0.1 to about 1 part by weight of a non-ionic or cationic wetting agent, to facilitate the penetration of the antistatic composition into the textile substrate. It is desirable that Add wetting agent in proportions determined beforehand by test in order to determine the degree of penetration of the To control the composition in the textile substrate so that the antistatic coating! composition penetrates the backing of the carpet and moistens the base of the staple fiber, without penetrating the outer supports of the paser. It is also advantageous to include 0.1 to about 1 percent by weight of one in the coating composition Incorporate electrolytes, especially if the humectant used is not ionic or only weakly is ionic, i.e. if it has a relatively small dissociation constant. The anti-static "coating material 6 is advantageous in the form of an aqueous solution or dispersion used, although also, other solvents or liquid dispersion media can be used. If aqueous solutions or dispersions are used, then

it contains volatile, water-soluble solvents, such as low-molecular, aliphatic ^ alcohols with 1 "to 4 carbon atoms, Acetone and the like included, which do the drying make anti-static protection easier.

After the antistatic coating 6 on the back layer of the When the carpet has been attached, the polymeric backsheet is then attached 8 on the carpet, thus forming an essential element of the carpet structure of the present invention. the polymeric backing layer is preferably used in the form of an aqueous dispersion (latex) and is advantageously a compound natural rubber-rubber or a compound carboxylated butadiene-styrene rubber rubber commonly used as a rubber backing for carpets, although other polymeric coatings such as Polystyrene, vinylidene chloride, polyacrylates, butadiene-styrene rubber and the like can be applied. As examples for known natural-compound rubber latices that in trade under the following names (= registered Trademarks) are named: Lotol GX-3180, U.S «Rubber Company, carboxylated styrene-butadiene composite rubber latices, such as Lotol G-X-1314, U.S. Rubber Company and Burkote A 2223, Burkart-Schier Chemical Company or composite neoprene latices such as Lotol GX-1076, U.S. Rubber Company or Burkote R 2285, Burkart-Schier Chemical Company.

To derive To facilitate the load in the ground, a material such as carbon black or any other material can be used in the polymeric coating 8 Means are incorporated that improve the dielectric properties of the polymer layer. There will be especially such antistatic compositions preferred in which potassium formate as a humectant Because potassium formate was used not only as a humectant is particularly effective, but also coating compositions with latex backing layers that normally Find use in carpets, make it compatible and especially the premature goagulation or gelling of the Latex back based on composed natural rubber overcomes and so the good bond of the latex cover interferes with the carpet backing. On the other hand, the antistatic coatings containing calcium chloride are with different, known latex coatings incompatible because they cause premature coagulation or gelling of the latex

Things which cause a ', low adhesion of the latex to the Carpet backing results, so that in the pail the loosely woven or tufted carpets the latex not the tufts of the holds firmly in place.

Although antistatic layers based on the antistatic compositions ^{7 are} particularly preferred, it is understood that any other antistatic layer which is known to be suitable for textiles and which dissipates charges caused by static electricity can be used. Such means are organic antistatic agents normally containing nitrogen or carboxylic acid, of which the following are mentioned;

Such alkylated amines are known in the literature and are prepared by condensing a primary saturated or unsaturated aliphatic amine having 8 to 22 carbon atoms with an alkylene oxide, usually ethylene oxide, although propylene oxide and butylene oxide can also be used until glycol residues of the desired chain length are obtained.

Various deliquescent salts of metals of the first and second groups of the periodic table, in particular the alkali metal and alkaline earth metal salts, can also be used as humectants in the compositions of the present invention. Special deliquescent salts, which are preferably used _{as humectants 9} include the alkali metal salts of low molecular weight aliphatic carboxylic acids, such as sodium formate, potassium formate, lithium formate, cesium formate, sodium and potassium acetate,

Potassium butyrate and mineral acid salts such as calcium chloride. Organic humectants such as glycerine, Urea, ethylene glycol, sorbitol, ethoxylated sorbitol, lauric acid ester and mixtures thereof can be used.

Bs is obvious that if a deliquescent salt is used as a humectant, it at the same time as Electrolyte acts. However, if glycerin or other non-ionic humectants are used, they should can be combined with an electrolyte. Even in the case of the Use of a deliquescent salt, such as sodium or Potassium formate, which has a relatively low dissociation constant it is advantageous to use a small amount of a salt of a strong base and a strong acid to incorporate. Such salts with a high dissociation constant are sodium chloride, potassium chloride or calcium ■ Chloride. Salts that do not dissolve satisfactorily enough are like sodium chloride, sodium sulfate or potassium nitrate and which are not sufficient enough as humectants and as an electrolyte can be used in combination with not ionic humectants such as glycerine or urea or in combination with more highly deliquescent salts such as Potassium formate or calcium chloride * can be used. So The detergents and electrolytes used in the composition of the present invention can be either one single compound or mixtures of these compounds

be.

If required, an additional back layer can be added, for example a jute backing, as indicated at 10 in the drawing, over the latex coating be attached; however, this jute backing is not an essential element of the carpet structure of the present invention Invention.

The details of the present invention are illustrated by the following examples in which parts are parts by weight are.

Examples Ibis 14;

In these examples the anti-static composition made by adding the base and organic acid in water to keep the humectant in situ to manufacture. The alkoxylated amine used is stearyl amine, which ethoxylates in 20 moles of ethylene oxide per mole of amine became. Tridecyl alcohol is used as a wetting agent was ethoxylated with 6 moles of ethylene oxide per mole of alcohol. The amounts used in the individual examples are
