Abstract

Sheets of felt-like character are made from an aqueous dispersion containing a mixture of fibres of three different kinds. Each kind comprises 10 to 80% of the total. The first kind of fibre is a tubular fibre of cellulose regenerated from xarthate solutions. The second is a natural or synthetic fibre; examples are polyamides, polyesters, regenerated cellulose, glass fibres, cotton and natural silk. The third is another synthetic fibre having a flow point at least 10 DEG C. below the flow points of the other fibres; examples are copolyamides, copolyesters, polylaurolactam and polypropyene. The sheet is made by pouring the dispersion on to a fourdrinier wire, dewatering, drying and subjecting to heat treatment at a temperature at which the fibres of the third kind soften, but the others do not. The heat treatment may be with saturated or superheated steam, hot air infra-red heaters. Heating may be by steam when the fibres of the third kind may soften at a lower temperature in steam than when dry. The heat treatment may be in two stages, the first above the softening point but below the melting point of the third fibres, the second above their melting points but below the melting point of the others. The heat treatment may be carried out free of tension, e.g. by carrying the sheet on the fourdrinier wire through an oven, so that the sheet can contract in its own plane and expand in thickness. When heat-treatment is in two stages, the first may be free of tension, but the second may be under tension, e.g. in a tenter. The dispersion may include a wetting agent, e.g. a polyoxyethylated fatty alcohol. The product may be pressed between rollers. The products may be used to make leather substitutes.
