Process Sequence:
Collar lining
canvas fabrics are normally not so heavy enough like the tent manufacturing
material. These are called canvas fabric because it backs and support the
collar in to a specified shape and form. Usually collar lining fabrics are of two types. Fusible and non-fusible collar lining.
Collar Lining (Non-fusible): Singe - Desize - Bleach - Mercerise are the regular process route for obtaining a suitable white material ready for finishing. The stiff finish recipe for collar lining is as below:
Poly vinyl acetate emulsion (Appretan EM) =250 gpl
Poly vinyl alcohol (PVA) = 25 gpl
Poly Ethylene Emulsion (PE) = 5 gpl
Anticreasing Agent (Finish MA (VLF)) = 100 gpl
Leucophor BFBI = 5 gpl
Leucophor TBLF
Magnesium Chloride = 1 gpl
Citric Acid = 0.3 gpl
Pad - Dry @ 110°C - Cure @ 150°C for 4 minutes.
Collar lining (Fusible) .
Nowadays only fusible type of
collar lining materials have good market potential due to their versatility in
application.
Singe - Desize - Bleach - Mercerise
- Bleach or Singe - Desize - Bleach are the two simple sequences selected by
the manufacturers of A prior stiff finishing with
a mixture of Poly Vinyl Alcohol and Poly Vinyl Acetate would help giving a body
to the fabric to be coated. After proper drying, the fabric ready
for collar lining proof, would be wound on spools of A - frames.
Powder Coating Process: (Fusible Collar Lining).
There are two kinds of polyethylene
fine granular powders are available in the market. One is called LDPE ( Low
Density Poly Ethylene) and the other one is called HDPE (High Density Poly
Ethylene) powder. These are free-flowing powders. The key characteristic of
this powder is its low melting temperature. Low melting temperature helps
to increase line speeds and lower energy costs.
Some of the salient feature of a
powder coating machine would be like the one mentioned below.
 1) Production speed: 12 - 25m/min
2) Power supply: 90kW, 380V, 50Hz
3) Coating width: 120 - 160cm
4) Advanced electronic components, intelligent temperature
control, display instrument, and motor speed converter
5) Equipped with unique fabric feeding device with selvedge calibrator and fabric opener
6) Increase qualified finished product rate
7) Heater does not use a boiler keeping temperature difference of less than ±2oC
8) Guaranteed even and stable powder point transfer
9) Conveyer heating chamber results in finished fabric having soft
touch
10) Stable hydraulic winding device allows for easy machine operation.
