Experiment Name : Study on industrial feed of the arm sewing machine with thread path diagram.
Introduction :
The machine which practices stitches by the loop of one group of thread links with the loop of other group of thread by the process of interloping is called the industrial feed of the arm...
Name of the Experiment: – Dyeing Jute yarn with Basic dye.
Introduction:
It is suitable for acrylic fibers (other fibers by mordanting). It reacts with acetic groups, or mordants a chemical which can react or complex with a chromophore to form an insoluble color in the fibre. It has good fastness...
Objectives :
To dye a material practically.To observe the practical advantages and disadvantages of this dye.To compare the theoretical idea with practical experiment.
Introduction :
Reactive dyes forms covalent bond with fibre polymer and thus attach itself with fibre. It is now a days mostly used for dyeing cotton yarn and...
Objects: The main object of this process is to print the fabric.
To print on the cotton fabric.

Introduction :
Dyes are coloured, unsaturated organic chemical compounds capable of giving colour to a substrate (a textile), i.e. colouring or dyeing it.
The term “disperse dye” have been...
Objects :
To find out the temperature and relative humidity of lab room
Theory:
Relative humidity is the ratio of actual vapour pressure to the saturated vapour pressure of the same temperature. Expressed as percentage.
Relative humidity = actual vapour pressure/standard vapour pressure.
An alternative definition for relative humidity is the ratio of the...
The Crockmeter is used to determine the colorfastness of the textiles to wet or dry rubbing. You can use the Crockmeter for the Crockmeter test and the Crockmeter price is also competitive. A pre-determined electronic counter is fitted in the Crockmeter for strokes of up to 999,999 times. The...
Tearing strength:
A fabric tears when it is snagged by a sharp object and the immediate small puncher is converted into long rip by what may be a very small extra effort. It is probably the most common type of strength failure of fabrics in use. It is particularly important...
Pilling:
Pilling is formation of little balls of fibers (pills) on the surface of a fabric which is caused by abrasion in wear.
Pilling is the tendency of fibers to come loose from a fabric surface and form balled particles of fiber.
Causes of Pilling:
Due to wear and abrasion.Due to rubbing action...
