Abstract

PURPOSE:A foundation for card clothing, obtained by using a high-density composite elastic mat prepared by entangling a piece of cloth having a high tensile strength integrally with a base layer, and capable of reducing remarkably the elongation of the foundation and improving the holding power and resilience of needles. CONSTITUTION:A foundation for card clothing obtained by laminating a nonwoven fiber web 9 formed by a web forming machine on one or both sides of a piece of reinforcing cloth 8 woven from spun yarns or filament yarns consisting of synthetic fibers as warp yarns, entangling the resultant laminate in a needle punching machine, and impregnating and fixing a binding agent solution consisting of a rubber or a synthetic resin emulsion into the resultant composite needle punched mat to form a high-density composite elastic mat 10 having 0.20-0.60 g/cm<3> apparent density, and using one or more pieces of the resultant elastic mat 10 in a base layer 7. Synthetic fiber yarns constituting the cloth 8 are preferably aromatic polyamide, polyester or polyolefin, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the construction of a base fabric for clothing, which improves the tensile strength of the base fabric, reduces the elongation rate, and improves the retention and elasticity of planted needles. In particular, the purpose is to greatly extend the life of the clothing. Conventionally, the base fabrics used for clothing are woven fabrics such as cotton cloth 1' and linen cloth 2, as shown in Figure 1. A plurality of pieces of cloth are used alone or in an appropriate combination, and are usually coated with natural rubber #111 as an adhesive and laminated one after another to form the base layer 6. The surface layer 4 is a rubber sheet with a thickness of 0.5 to &Ow II, or sponge rubber. It is formed by bonding sheets, resin sheets, felt with a thickness of 3.0 to 4.5 mm, etc. with an adhesive 5 depending on the purpose of use. Steel needles are carefully implanted into this base fabric, the needle heads are aligned, and the needle cloth is made by polishing. In recent years, the spinning industry has aimed at high-efficiency production of cards, and has continued to operate cards for long periods of time.
As a result of higher rotational speeds and a drastic increase in the amount of processed fibers, the wear and tear on the clothing provided in the cards has become very severe. 7, the load of carding axis binding has become extremely harsh on the base fabric,
A base fabric made of several pieces of woven fabric such as cotton cloth pasted together cannot withstand the damage, and during use, the base fabric gradually stretches due to the constant load and rises from the card drum.7tj+s
) In the case of hemlock clothing, a so-called floating phenomenon occurs in which the fabric rises up from the fixing plate and becomes hollow, resulting in accidents such as falling needles, broken needles, and cutting of the fabric. The present invention is intended to solve the above-mentioned drawbacks, and as a result of various studies, it has been achieved by greatly reducing the width of the base fabric O stretch skewer and improving the retention and elasticity of the needle. Spun yarn or filament yarn of synthetic fiber with low elongation and low tensile strength is used as at least the warp IK
At least one high-strength composite elastic mat made by needle-punching a laminate of reinforcing woven fabric and non-woven fibers and impregnating and fixing it with rubber or synthetic resin is used as the base layer of the base fabric. This eliminates various problems caused by the elongation of the base fabric and extends the useful life of the clothing.

Next, the configuration of the present invention will be explained in detail with reference to the drawings.

As shown in FIG. 2, the surface layer 6 has a thickness of 0.5 to 3.5 mm.
A rubber sheet with a thickness of 3.5 to 4.5 mm, a sponge rubber sheet, a resin sheet, a compressed felt mainly made of wool fibers with a thickness of 3.0 to 4.5 mm, or a needle punch felt made of synthetic fiber material 9, etc. are appropriately selected. (For example, thickness 451ff
i compression fer) 1 is used. ) The base layer 7 is made of a reinforcing woven fabric 8 woven using synthetic fiber yarn with low elongation and excellent tensile strength, such as spun yarn or filament yarn of aromatic polyamide, polyester, polyolefin, carbon, graphite, etc., as at least the warp yarn; On one or both sides of the woven fabric, synthetic fibers such as polyester, polyamide, polypropylene, acrylic, etc., condensate fibers such as acrylic, polyamide, polyester, polyolefin, elastomer, etc., inorganic fibers such as glass and metal, Regenerated rayon, nose plastic, acetate, etc., chemical fibers such as biosynthetic fibers can be used individually or in combination! Non-woven fiber wear 9 with a basis weight of 100 fAa' to 800 jE/iB" formed by a web forming machine using a combination of several kinds, or using wool alone as a natural fiber or mixed with the above-mentioned chemical fibers is laminated. Then, the above woven fabric and non-woven fiber web are intertwined and integrated using a needle punch machine to form a composite needle pine) Th. A mat can also be formed.

The above composite needle pine) t-natural rubber and NBR.

Synthetic rubber latex such as 813R, OR, BR, AER, VR, etc., acrylic, synthetic resin emulsion, etc. are impregnated and fixed in a selected binder solution to obtain an apparent density of 0.20 to 0. The above composite rubber or synthetic rubber adhesive or synthetic resin adhesive is used to form a high-density composite elastic mat 10 of 60 F. A base layer 7t4N0 is formed by bonding two pieces of chisel with the above adhesive, and then this base layer 7 and the surface layer 6 are bonded together with a rubber or synthetic resin adhesive 12 to form the base fabric for clothing of the present invention. do.

As mentioned above, by using at least one high-density backing elastic mat in which woven fabrics with high tensile strength are intertwined as a base layer, the elasticity of the base fabric increases and the elasticity becomes stronger, improving the needle holding power. A base fabric for clothing having low elongation and high strength can be obtained.

Hereinafter, the present invention will be explained in more detail with reference to Examples.

Example: Aromatic polyamide woven fabric (Kepler (manufactured by Deobon Co., Ltd.) filament bundle with a warp of 1140 denier, 17 pieces, 725.4
100% good fabric between 54 cotton threads (725.4cm plain weave) and 411x76 polyester
5 o y/rr? After laminating the non-woven fiber webs, the woven fabric and the non-woven fiber web are intertwined and integrated using a needle punch machine to form a composite needle mat with a diameter of 45 mm and a thickness of 45 mm.This composite needle mat is made into BBR. Impregnated with a binder liquid mainly composed of latex, dried and subjected to 1 cross-linking process, with a fabric weight of 600 f/, l and a thickness of 20
A composite elastic mat with an apparent density of 0.3-0.3 was formed.

A base layer is formed by laminating cotton cloth on both the upper and lower surfaces of the above composite elastic mat with all-natural rubber glue, and one side of this base layer is coated with a thickness of 4 mm.
A base fabric for clothing was constructed by laminating two surface layers of NBR sponge rubber sheets together with a synthetic rubber adhesive.

4. Characteristics of the above-mentioned clothing base fabric of the present invention and a conventional clothing base fabric B (a product laminated with a sponge rubber sheet on the surface layer and 6 cotton fabrics and 1 juza fabric on the base layer) as a comparative example. The values are shown in the table below.

As mentioned above, the base fabric for clothing of the present invention has a base layer made of high-density composite elastic pine, which is an interlaced and integrated non-woven fiber web and a laminated fabric with low elongation and high tensile strength. As a result of use, the elasticity of the base fabric increases, the waist is strengthened, and the gripping force of the implanted needle increases, and it also has low elongation and high strength, so the base fabric floats. ) T full decreased steadily. In addition, this invention has excellent effects such as being able to greatly reduce the number of sheets of cotton cloth, linen cloth, etc. used for the base layer, and thereby shortening the lamination process of woven cloth. .
