METHOD OF OBTAINING TUFTING COATING Russian patent published in 2012 - IPC B32B27/12 D04H11/08 D06N7/00 

FIELD: manufacturing process.

SUBSTANCE: invention relates to the textile industry, in particular to a method for manufacturing tufted material, used as flooring, as well as for interior decoration. The method consists in applying a binder - fine hot melt polyethylene powder, on the secondary synthetic non-woven substrate. The binder while heated turns into a plastic condition. Then under pressure it connects the secondary substrate with a primary polypropylene woven substrate, stitched with pile of synthetic yarn. The application of the binder is carried out on the secondary substrate, while its progress and effect of temperature on top. The connection of the primary substrate and the secondary substrate with a binder in a plastic condition is carried out under a pressure of 0.3-0.7 MPa, while the impact of the temperature of the lower calender of 130°-150° C and the temperature of the upper calender of 50°-80° C. The primary substrate is fed directly into the joint area of layers, at a rate of admission of the secondary substrate with the binder. In the result manufacturability of the carpet is improved due to separation of stages of the binder melting and the layers connecting.

EFFECT: increased strength of binding of substrates across the surface while maintaining the appearance of the pile layer.
