Abstract:
Stentering is the process of Stenter Machine that is use to finished the knit fabrics to control
different parameters like diameter, GSM, shrinkage, spirility, shade of fabrics etc. this machine
is very important for knit fabric finishing section. We work with this stenter machine for our
research purpose. Here we include the definition of stenter machine, working procedure of
stenter machine, specification of stenter machine, different parts name with picture, stentering
process for dyeing fabrics and stentering process for undyed fabrics, we find out the changes
of different parameters for this we takes different types of samples polyester single jersey,
(1*1) Rib, Lycra single jersey, fleece, single jersey, waffle, cotton single jersey, single lacost
etc.). The main purpose of this project is to evaluate the stentering performance on different
types of knit fabrics on the basis of different GSM and different Diameter. This research mainly
focused on changes of different parameters (CPI, WPI, SL, GSM, Shrinkage, and Diameter)
of different knit fabrics after stentering process. The aim of this project is to measure GSM,
CPI, WPI, SL, Diameter, and Shrinkage before stentering and after stentering and calculate the
changes % of those parameters. After completing the research we found that the most changes
of GSM on Lycra single jersey fabrics is 38.98%, and lowest changes of GSM on single jersey
fabrics is 3.03%. The most CPI changes on Lycra single jersey fabrics is 36.98%, and the
lowest changes on Fleece terry fabrics is 5.26%. The most changes of WPI on Lycra single
jersey fabrics is 39.65%, and the lowest changes on Fleece terry fabrics is 5.88%. The most
changes of SL on Lycra single jersey fabrics is 38.82%, and the lowest changes on Single
jersey (160GSM) 3.53%. The most changes of Diameter on (1*1) Rib fabrics is 25.47%, and
the lowest changes on polyester single jersey is 0.79%. The most changes Shrinkage is 5.81
on Waffle fabrics and lowest changes is 0.3 on single lacost. From this research we learn about
how to find out changes of GSM, CPI, WPI, SL, diameter, Shrinkage % and control them.
