Fibres 10 comprise discrete regions of polypropylene 18 that are surrounded by polyethylene 20. The fibres are connected together by heating the fibres such that as the melting point of the polyethylene is approached or reached or passed the abutting surfaces of the fibres soften and adhere together to become integral. Heating of the fibres causes shrinkage of the fibres such that a fabric formed from such fibres shrinks to pull the fibres together on heating. The fibres relax after their initial contraction to lose a lot of the tension that caused the fibres in the fabric to be drawn in. |
