<p>A method of forming batts for insulating purposes and using fibres derived predominantly from waste wool material comprises incorporating with the fibres up to 25 % bonding fibres of a thermoplastic or similar material having a softening point or melting point of between about 120°C and 200°C, forming a mat of desired thickness of the fibres and bonding fibres with the fibres randomly dispersed, causing the bonding fibres to soften to a tackiness, or melt, by increase in the temperature thereof, whereby the bonding fibres or the melted fibres, adhere other fibres together to maintain the random spacing of the fibres of the mat and hence the loft thereof.</p> |
