Disfigure-resistant plastic-string mat

Abstract

A disfigure-resistant plastic-string mat includes a scraping layer and a lattice-shaped layer fused under the scraping layer. The scraping layer is made of plastic elastic strings formed randomly and irregularly into piled up countless rings interlocking an intercrossing with one another to define countless gaps. The lattice-shaped net layer is woven of fiber of high strength and fused with the scraping layer by means of immersion in plastic solution homogeneous with the scraping layer under high temperature, and firmly combined with the scraping layer after cooled so that the scraping layer may not easily shrink or lengthen, constricted by the lattice-shaped net layer.

Description

[0001] 1. Field of the Invention[0002] This invention relates to a mat, particularly to one disfigure-resistant mat made of plastic string.[0003] 2. Description of the Prior Art[0004] Mats are commonly placed at the entrance or the doors of living houses or public buildings, for scraping off dirt, mud or water stuck under shoes by friction between the mats and shoes, so inner floors may not be smeared.[0005] A conventional plastic-string mat 10 is shown in FIG. 1, made of high-molecule plastic elastic slender strings 11 randomly and irregularly interlocking and intercrossing with one another. Then it has countless gaps 12 formed among them. Therefore, the plastic slender strings 11 may produce friction force to effectively scrape dirt, mud or water adhered on the bottom of shoes worn by people, and dirt, mud or water may drop down through the gaps 12 among the plastic strings 11 to the ground where the mat is placed. Then the upper surface of the mat 10 does not have dirt, mud or wa...

AI Technical Summary

Problems solved by technology

However, as the conventional plastic-string mat is made of plastic, which is generally contractible, it may shrink to smaller size than its normal one and does not cover the area it needs to.

Further, the interlocking and intercrossing plastic strings may produce looseness and elasticity to lower its counter tension force, and once the plastic strings 11 are pulled badly enough to snap, it is not suitable for washing in a washing machine, but have to be washed manually and carefully.
