文摘Discussed in the article are the factors for the imperfect quality of piecing based on the principles and the key technologies of semiautomatic piecing. Furthermore, three measures including changing the shape of seed yarn tail, changing the feed speed and removing the damaged fibers are put forward. Experimental results prove that the former two, especial the second one, offers better piecing quality.
