Poly/Cotton Core Spun Sewing Thread


Polyester/Cotton core spun threads are produced by spinning the staple fibres of cotton and then wrapping this around continuous polyester filaments.Two or more plies of this standard yarn are doubled (twisted together) to make the sewing thread. The resultant thread provides superb strength from the polyester filament together with the characteristic soft feel of the cotton. The thread lubricant is retained well by the surface fibres which result in excellent sewing performance. The cotton offers good protection against needle heat.
