ABSTRACT:
Spandex having dispersed within it particles of a mineral mixture of huntite and hydromagnesite has decreased tackiness, increased resistance to chlorine-induced degradation, satisfactory process continuity and little extraction of the mineral mixture in typical acid scouring and dyeing operations. The particles do not lead to excessive abrasiveness and are environmentally acceptable in effluent streams.
