The
property of the textile water for which it does not
form foam easily without a lot of soap is known hardness of water. It has two
types named temporary hardness and permanent hardness.
3.
What is PPM?
The
number of grains of calcium carbonate which is present in one millions grains
of water is termed as PPM.
4.
What do you mean by degree of hardness?
The
number of grains of calcium carbonates which is present in 70000 grains of
water is known as degree of hardness of water.
5.
What is water softening?
To
remove the impurities of hard water by some desirable process is known as water
softening.
6.
What is soap?
Soap
is a metallic salt of saturated or unsaturated higher fatty acid. There may be
Pb, Mg, Ca or other metallic salt.
7.
What is detergent?
The
compound which gets orient at the interface between water and air and reduces
interfacial tension or surface is known as detergent. It is mainly two types
named ionic and non-ionic.
8.

It
is one types of bio catalyst. It is based on protein. It is soluble in water
but insoluble in acid and alkali.
9.
What is Chroma?
The
dullness of vividness of color describing is known Chroma.
10.
What is shade?
The
meaning of shade is concentration. Usually, the depth of the tone of color is
known as shade. It is three types such as light shade, medium shade and deep
shade.
11.
What is pigment?
It
is normally a substance in particulate form which is substantially insoluble in
a medium but which can be mechanically dispersed in this medium to modify its
color and light.
12.
What is stripping?
If
the textile goods become uneven dyeing and insoluble for using then the color
has to be distorted. The process to destroying of removing dye or finish form
fibres or fabrics is known as stripping.
13.

dyed substance in order to adjust the latter to the desired final color is
known as topping.
14.
What do you mean by after treatment?
The
process which is used for proper and perfect dyeing action is known as after
treatment. In case ofdirect dye, after treatment is done for
increasing light fastness and wash fastness of dyed materials. Dye particle is
done insoluble into the fiber after treatment.
15.
What is vatting?
The
action which helps to insoluble vat dyes to be used by soluble is called
vatting.
16.

giving viscose paste in water. Thickener imparts stickiness and plasticity to
the printing paste so that it can be applied to a fabric surface without color
spreading.
17.
What is viscosity?

ratio of the velocity to the clearance is known as shear rate.
20.
What is ageing?
It
is consisting of exposing printing goods to more or less prolonged action of
steam at atmospheric pressure to assist in the diffusion and fixation of the
dyes.
21.
What is steaming?
