JPH01272871A - Hardly slipping large-mesh processed cloth - Google Patents

Abstract

PURPOSE:To obtain a hardly slipping large-mesh processed lightweight cloth, rich in durability and suitable as a lining of mats or carpets, by integrally covering the surface of constituent yarns of the large-mesh substrate cloth with a resin foam. CONSTITUTION:An expandable resin solution prepared by adding a foaming agent to a substrate resin, such as polyvinyl chloride or polyurethane, is applied to the surface of constituent yarns in a large-mesh substrate cloth. The resultant cloth is then heat-treated to expand the resin solution and integrally cover the surface of the constituent yarns in the above-mentioned large-mesh substrate cloth.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a non-slip coarsely textured cloth suitable as a lining for carpets, cloaks and other rugs.

Conventional technology Rugs such as carpets and cloaks, which have been commonly used as part of furniture, have a slippery back surface, so they tend to move or wrinkle due to lateral forces caused by walking. .

In order to solve this problem, we developed a rug with a non-slip rubber material attached to the entire back surface and a rug with a polyurethane foam non-slip component partially installed on the back surface (1986).
-109366) is provided.

However, the former is not only expensive but also heavy, making it difficult to move for sale, installation, cleaning, etc. In the latter case, each anti-slip member is partially and independently installed. Since it is disposed on the back surface, it tends to peel off from the back surface and has poor durability.

Problems to be Solved by the Invention The present invention has been made in order to solve these problems and provide a non-slip cloth that is lightweight, has excellent durability, and enables the production of a non-slip rug.

Means for solving the problem, that is, the present invention relates to a non-slip rough textured cloth in which the surface of the constituent threads of the coarse base material cloth is integrally covered with a resin foam.

Hereinafter, the present invention will be explained based on the accompanying drawings.

FIG. 1 is a partial schematic plan view showing one embodiment of the non-slip coarsely textured cloth according to the present invention.

FIG. 2 is a schematic sectional view taken along line A--A in FIG. 1.

Examples of materials for the weft (1) and warp (2) include glass fiber, vinylon, polyester, nylon, and blended yarn.

Examples of the base material cloth include a plain weave, a leno weave, and an adhesive scrim having a weave of usually 3 mm to 50 mm.

Examples of the resin foam (3) include polyvinyl chloride and polyurethane. If desired, the resin foam (3) may be colored by appropriately blending pigments and the like.

The coating thickness of the resin foam (3) is not particularly limited, but is usually 0.2 mm to 1 mm. The texture of the rough-textured cloth according to the present invention is usually 3 squares to 50 squares.

The non-slip rough textured cloth according to the present invention can be produced, for example, by attaching a foamable resin liquid to the surface of the constituent threads (1) and (2) of the coarse base material cloth, and heating and foaming the adhered resin. I can do it.

The foamable resin liquid contains a base resin such as polyvinyl chloride polyurethane, a foaming agent (e.g. toluenesulfonyl hydrazide, dinitrobenzethylenetetramines, etc.), a filler (e.g. calcium carbonate, titanium oxide, etc.), and a plasticizer (e.g. dioctyl 7-talate). , benzyl butyl phthalate, etc.) and optional pigments.

A convenient method for attaching the foamable resin liquid to the coarse substrate cloth is to immerse the latter in the former or to spray the former onto the latter.

The heating and foaming temperature of the foamable resin liquid attached to the surface of the constituent threads (1) and (2) of the coarse base material cloth depends on the type of foaming agent. For example, when toluenesulfonyl hydrazide is used, the temperature is about 100°C, and when dinitrobenzethylenetetramines are used, it is about 100°C.
It is 20°C.

The coarsely textured cloth according to the present invention, that is, the non-slip coarsely textured cloth made by integrally covering the constituent threads (1) and (2) of the coarsely textured base material cloth with a resin foam (3) can be used for carpets, mats, etc. (For example, entrance mats, bath mats, etc.) As a lining for rugs, it can be glued or sewn.
Suitable as a non-slip material. In addition, simply interposing the anti-slip material between a floor surface and a carpet such as a carpet or mat serves as a simple anti-slip material. In addition to this, it can be used for various other purposes. For example, it can be used as a grass net with a coarse weave (20 mm or more), lightweight, flexible, easy to follow on slopes, and excellent in preventing grass seeds from flowing out. It also has good rust prevention and workability, and is effective as a substitute for wire mesh lath for construction work.

Hereinafter, the present invention will be explained by examples.

Example 1 A foamable resin liquid (polyvinyl chloride sol) was prepared according to the following formulation: Component Amount (parts by weight) Polyvinyl chloride 37.6CaCOs
14-5 Dioctyl lactate 28 Benzyl butyl phthalate 7.3 Dioctyl adipate 6.0 Zinc complex (1) 1.3 Additive 1 (

(3) 2, 6 (1) Zinc stearate (2) Mixture of 60% by weight of azodicarbonamide and 40% by weight of epoxy-octyl stearate (3) Mixture of 7% by weight of colloidal polyester and 93% by weight of dioctyl phthalate This foamable resin liquid was applied to a vinylon fiber lattice scrim in the proportions shown in Table 1, and then heated and foamed under the conditions shown in Table 1. 10 were manufactured.

When these rough-textured cloths L to 10 were adhered to the back side of a commercially available entrance mat (50 cm x 60 cm) and a carpet (180 cm x l 80 cm) with flat back sides using an adhesive (vinyl acetate resin) and put into use,
Compared to similar entrance mats and carpets made of the same coarse-grained cloth without bonding, the slip resistance against lateral external forces due to walking etc., that is, the installation stability, has been greatly improved. Roughly textured cloth with a relatively large amount of foam adhesion 4.5.
The installation stability of the entrance mat and carpet to which Test Nos. 6 and 9 were adhered was good.

(Hereinafter, blank spaces) Table 1 Effects of the Invention The rough-textured cloth according to the present invention is lightweight, has excellent durability, is hard to slip, and is highly visible, so it is particularly suitable as a lining for mats, carpets, and other rugs. be.
