Importance of textile Testing:
Textile
testing is important mainly for customer satisfaction of textile product as
well as to ensure product quality.
Testing
is valuable aid for textile production we can research work, selection of raw
materials, process control, process development by testing, Textile testing is
extremely important in determining the quality and performance of product.
Determine
of the pH value: Iso3071
Aim
and application:
Determine the pH value of the aqueous extract of
textile material’s.

| pH Mater |
APPARATUS REQUIRED:
01. Balance accurate to 0.05g,
to weigh 2g of the material to be tested.
02. Glass beakers, chemically
resistant: of capacity 250ml.
03. Glass stopper flasks,
chemically resistant of capacity 250 ml.
04. Distilled or detonated water
having pH between5.0-6.5.
05. Measuring cylinder
chemically resistant, capacity 250 ml.
06. Mechanical shaker. A to and
for movement at a rate of 60 miri-l or a rotational frequency 30min – I have
been found satisfactory.
07. pH meter, discriminating to
at least 0,05 in pH and suitable electrode system.
Procedure:
01. Tale 2 g of the
fabric to be tested and cut it into pieces with approx. 5mm sides.
02. Place the catted pieces in
to the glass stopper flask.
03. Add 100 ml of the distilled
water of the STOPPER AND AGITATE TO ENSURE THE textile is properly whetted out.
04. place on the mechanical
shaker, and shake for two hours at a rate of 60rpm.
