New Polishing Processing Technology of Dust-free Knitted Fabrics
In view of the production of earring-type knitted fabric with high cloth finish and anti-pilling requirements,and easy to produce the problem of dust removal,the use of multiple hair burning process will not only bring the risk of unsmooth finish and the appearance risk caused by incomplete removal of hair.And the conventional cellulase polishing treatment will bring serious hair dust loss problem.In this paper,the special hair grinding process was adopted to pre-hair treatment with the appropriate singeing treatment,which not only ensured the complete removal of hair,but also ensured the quality indices such as hair ball and hair dust to meet the customer standard.The results show that the grinding material adopts polyyl ammonia material,supporting the best grinding process is:the speed is 15 m/min,the grinding time is 1 time,and the pressure depth of the mill is set at 70％.The matching singeing process is:the singeing method is cutting and burning,the flame strength is 1.5 MPa,and the running speed is 85 m/min.The different earring-type knitted fabric have relatively stable cloth finish,anti-pilling,dust removal and dry and wet friction fastness performance.
