This fibre represents a mixture of acrylic fibres of different production types, linear density and colors.
Type Zh – technical fibre composed of pieces of different length, mixed, after all stages of acrylic fibre manufacture process before crimping. It is intended for usage as a feedstock during production of geotextiles, nonwovem materials and other technical application articles that do not contact with human skin.
Type M – technical fibre composed of pieces of different length, mixed, after all stages of acrylic fibre manufacture process before washing and drying. It is used as a feedstock for production of water soluble emulsions and technical compositions for special usage.
