Abstract:
The textile factory in Bangladesh, specially the knit industries, where a huge amount of knit
fabric is produce in daily basis. There also numerous types of raw material like yarns, various
types of count of yarn are used according to the requirement of production. So in this aspect,
though the production procedure is same for different knit products, major differents are seen
during the time of production. It has been seen in often that the amount of production of fabric
are few less with respect to the amount of inputting yarn. It has been recalled as the termed as
Process loss (Process loss of yarn). Now question is what the reason behind this process loss is
and how much amount in wt. of yarn wasted during production. To find out the answer of these
question we have seen that the process loss impacted by some factors during production, Such
as, Types of yarn, Yarn composition, Count of Yarn, Brand of Yarn, Yarn package, m/c r.p.m.
skill of operator, yarn tension , loading of yarn , relative humidity etc. All necessary data‟s have
been collected for day long above 8 hour per day (1 shift), and they were collected and rearrange
as a form of Microsoft office word. And this thesis showed the find out the process loss for each
of the criteria at a time for each of the single machine. Through this thesis work it is clear that
the wastage of yarn is more in case of foreign brand compare with local brand during knitting.
