Abstract

A method of preparing a non-woven web of fibres which may be used as a substitute for leather, comprises needling a batt of fibres to cause them to become intermately intermingled, bonded the fibres together by impregnation with a bonding medium and splitting the batt to provide at least two separate sheets. The splitting may alternatively be done prior to the impregnation and the batt can be split to provide a plurality of sheets in addition to the two separate exterior sheets. The batt may be formed by cross laying carded webs of fibres or by air laying and the fibres are preferably synthetic fibres of high tensile strength selected, e.g. from linear polyester fibres, nylon, polypropylene and acrylic staple fibres or may be a mixture thereof. Fibres of natural or synthetic origin and of a lower tensile strength, e.g. viscose, wool, regenerated protein fibres or alginate fibres may also be included. A staple length of 3 to 7 inches is preferred hub yarns formed of twisted strands of undefined staple length and fibres obtained from bulked yarns may be used. In order to provide water vapour permeability some of the fibres are preferably water sensitive unless a water sensitive bonding agent has been used and such water sensitive fibres may be embedded in the batt in the form of flock. Suitable bonding agents are flowable compositions based on synthetic rubber, a polyurethane, polyvinyl alcohol reacted with sufficient formaldehyde to form a product insoluble in water but capable of absorbing and transmitting water vapour, a solution of collagen or a water sensitive polyurethane. The proportion of bonding agent to fibres may be from 20 to 150 parts by weight of bonding agent to 100 parts of total fibre and the material formed according to the invention may be further treated on one side with an additional bonding agent such as a rubbery polyester or polyurethane and may be coated with any conventional leather finish to give a wear resistant surface. To assist the needling operation the batt may be impregnated with a lubricant.
