Abstract

A composite material which comprises a man made fibre, such as Polyester, Nylon or Dacron, and latex rubber in sheet, block or roll form. The material is made by dipping or spraying a man made fibre in or with latex solution, the man made fibre then being compressed between rollers or nips to ensure thorough deposition of the latex around the fibres and to remove excess latex, before being vulcanised in a heated press and pressed to a required thickness and density. A flame retardant is preferably added.

Description

DESCRIPTION A COMPOSITE MATERIAL AND A METHOD OF PRODUCTION THEREOF The present invention relates to a composite material comprising a man made fibre and latex rubber and a method of producing the composite material. The composite can be used as an alternative to foam rubber.
Foam rubber has been used widely in many applications where any one number of its physical properties are of importance such as softness, resilience and elasticity, flexibility and malleability. However foam rubber has disadvantageous properties in that it is not recyclable or biodegradable. There are many applications where foam rubber would be unacceptable due to its chemical constituents or because of the derivatives produced as a result of combustion (fire, smoke, fumes etc.) or chemical reaction. Thus foam rubber is unsuitable for seating or insulation in aircraft, trains and motor vehicles, cot mattresses, military packaging, seating and bedding in war ships and packaging used in the transportation of nuclear products.
Rubberised hair, or rubberised hair and coir fibre, has been used as an alternative to foam rubber particularly as an upholstery filling or as a moulded cushioning medium. The composite is produced by spraying strands of hair or hair and coir fibre with latex, preferably containing a flame retardant, and the mixture compressed, heated and vulcanised to form sheets of rubberised hair or hair and coir fibre.
Sheets can be pressed and heated one to another to produce a secure interface and hence thicker material.
The material is elastic under compression and is more flame retardant than foam. However it is also coarser, heavier less resilient and less elastic than foam rubber and slower to recover from compression.
An object of the present invention is to provide materials which are satisfactory alternatives to foam rubber for use in applications where it is rendered unacceptable due to its chemical constituents or because of the derivatives produced as a result of combustion or chemical reaction. A further object of the present invention is to provide methods of making these alternative materials.
According to one aspect of the present invention there is provided a composite material characterised in that it comprises a man made fibre and latex rubber.
According to a further aspect of the present invention there is provided a method for covering the fibres of a man made fibre with latex to produce a composite material characterised in that the man made fibre is dipped in latex solution.
According to yet a further aspect of the present invention there is provided a method for covering the fibres of a man made fibre with latex to produce a composite material characterised in that the man made fibre is sprayed with latex solution.
It is preferable that the composite contains a flame retardant and that the man made fibre is supplied in sheets (including rolls) or in block form.
If the man made fibre is dipped and particularly if it is sprayed it is preferable that it is then compressed between rollers or nips to ensure thorough deposition of the latex around the fibres and to remove excess latex.
The composite in accordance with the invention has a better appearance than the known rubberised hair in that it has smoother, smaller and more uniform fibres. It is, in addition, softer in feel, more resilient and more elastic, recovering quickly after compression. Although both materials can contain a flame retardant, the properties of a man made fibre and its ability to "shrink" from the flame results in increased flammability resistance.
Compared to foam rubber, for example as used as an upholstering filling, the new material has a similar "feel". Advantageously, the latex of the composite is biodegradable and some man made fibres e.g. Polyester are recyclable. The new composite, preferably containing flame retardant, is also less flammable and the products of combustion or chemical reaction less noxious than conventional foam rubbers.
Therefore the composite could be used for applications where foam rubber was deemed unacceptable.
The invention will now be described by way of example only. In one embodiment of the invention, the man made fibre, for example Polyester, Nylon or Dacron, is produced in sheet form by normal manufacturing methods. The sheet is dipped into latex containing a fire retardant, so as to be totally immersed. The sheet is then compressed between rollers to ensure full penetration of the latex into the sheet and around the man made fibres and to remove excess latex. The material is then dried and vulcanised in a heated press and pressed to the required thickness and density.
In an other embodiment, the dipped wet material is put into mould and then vulcanised by heat.
