 Year of establishment : 2007
 Per day production : 1,80000 mt
 Varieties run on PTR 1 & PTR 2
1) 100% Cotton
2) Polyester/cotton blend
3) Lycra/cotton blend

3. WHAT IS PRETREATMENT PROCESS ?
 The process in which we remove all the natural
as well as added impurities & natural color from the
fabric is known as pretreatment process.

4. WHY IS PRETREATMENT REQUIRED?
 As a whole this process consist of singeing , desizing ,
scouring and bleaching process.
 pretreatment process basically aim to removal all impurities
found on fabric so that materials have -
 1) Degree of white,
 2) Absorbent to dyestuff.

NOTE : - Desizing steamer of PTR 1 is without roller-bed so we can't set the dwell
time but desizing steamer of PTR 2 is with roller-bed so we can set the dwell time till
04 to 40 minutes.

28. WINDOW OF SINGEING BURNER
PTR 1
PTR 1 has small
window so it's not
prvoide as
visualization as PTR 2.
PTR 2
 PTR 2 has large window
at singeing so it provides
more visualization which
help to find the mistakes
easly.

32. OBSERVATIONS
 Counter-current washing mechanism is used in washers.
 Use of hot water lowers the amount of steam consumption.
 At VDR amount of steam supplied depends on the article.
 In steamer we use wet steam & in washers and VDR we use dry
steam.
 Dwell time of PTR 1 is 28.03 min whereas PTR 2 is 25.66 min.
 Fabric content of PTR 1 is 2803 mtr whereas PTR 2 is 2308 mtr.
 No. of washers are 10 in PTR 1 whereas in PTR 2 is 7 .
 PTR 1 has 3 steamers and PTR 2 has 2 steamers.
 We use heat exchanger at every section.
 Outlet j-scray height of PTR 1 is 4 mtr and PTR 2 outlet j-scray height
is 5 mtr.
 PTR 1 has 2 fortracta whereas PTR 2 has 2 trikoflex.
 Electronic sensors is on outside of the steamer in PTR 2 whereas in
PTR 1 electronic sensors is inside on the roller.
 Spreader for openning selvedge fold is available in PTR 2 whereas in
PTR 1 it's not available.
 Quick machine stop button is available in PTR 2 whereas in PTR 1
it's not available.
 Drain is on the side of the machine in PTR 2 whereas in PTR 1 it's
bottom of the machine.

33. CONCLUSION
 At singeing section in PTR 2 we have 4 flame position who provides
more smooth surface.
 At singeing section in PTR 2 we have automatic selvedge extinguisher
which maintain better selvedge protection.
 At desizing section in PTR 2 we can mix chemical separatly so PTR 2
provides more efficiency in chemicals according to the fabric
requirement.
 At desizing section in PTR 2 we have a with roller-bed steamer so we
can set the dwell time in desizing chamber .
 In PTR 2 we can do batch-wise process so we have a option for cold
bleaching.
 PTR 2 has batch-wise process so we can send the fabric direct to
bleaching or mercerizing and other process after singeing.
 PTR 1 has fortracta whereas PTR 2 has trikoflex and trikoflex is a
advance cleaning system so PTR 2 provides more cleaning efficiency.
 In PTR 1 we have separate section of scouring & bleaching but in PTR
2 we do combined process of scouring & bleaching so we have
advantage in PTR 2 of low threading length & short time processing.
 In PTR 2 we can instant changes in chemicals but in PTR 1 we can't.
 For full white fabric we use PTR 1 because it gives good result.

34. MY SUGGESTION
 We should apply a star roll at singeing section in PTR 1
because fabric stucks many times while coming in inlet
S-scray.
 We should increse the height of outlet j-scray of PTR 1.
 We should repair the selvedge extinguisher of PTR 2.
