Abstract: Based on the properties of the stainless steel staple fiber,mixed it with cotton fiber since their elongations are similar.The cotton spinning system was used with processing process adjusted to adapt to the particularity of the fibers.The experiment results indicated that it is feasible to spin the stainless steel staple fiber/cotton yarn on a cotton spinning system.However,being high tenacity but low elongation,the stainless steel staple fibers are damaged seriously and have as low as a 70% finished product rate.
