Influence of Process and Machine Variables on the Blend Characteristics of Rotor Spun Yarns

The influence of process and machine variables on various parameters of blending has been investigated. It has been observed that the mixing stage has very little influence on the blend characteristics of rotor spun yarns. The results also indicate that preblending cannot be used as a substitute for rotor doublings. In terms offibre dispersion and arrangement offibres in the yarn cross-section, beater feed machine gives better results compared to the roller feed machine.
