A bigger step in fiber technology hollow bicomponent fibers are made of 2 different polymers hollow bicomponent fibers have great insulating and moisture management properties, lightweight, and high durability. as the demand for high performance textiles continue to rise, hollow bicomont prisms are used in clothing, insulation, and filtration systems. as the pioneer in the high performance textiles fiber industry, we continue to develop innovative fiber solutions to meet the hollow bicomponent fibers market.
