Randomized trial examines carding parameters affecting yarn quality in cotton yarns, highlighting the role of linear density.

The study aims to investigate how various carding process parameters influence the quality of yarn produced from long-staple cotton.
Utilized a four-factor, five-level central composite design for experimentation.
Examined parameters including cylinder–licker-in speed ratio, cylinder speed, doffer delivery speed, and feed lap mass.
Produced yarns with linear densities ranging from 17.6 to 31.5 tex under controlled laboratory conditions.
Feed lap mass significantly affected breaking work and short hairiness before adjustment by yarn linear density.
Interaction between cylinder–licker-in speed ratio and feed lap mass significantly influenced long hairiness after adjustment.
Yarn evenness CV% was poorly explained, while the irregularity index exhibited a significant linear response.

Wang et al. (2026) studied this question.
