Denim Washing
Denim washing is the aesthetic finish given to the denim fabric to enhance the appeal and to provide strength.
Much of the appeal of dry denim lies in the fact that with time the fabric will fade in a manner similar to
that which artificially distressed denim attempts to replicate. With dry denim, however, such fading is affected by the body of
the person who wears the jeans and the activities of their daily life.This creates...

FAULTS IN DENIM PRODUCTION
FALUTS IN MACHINE:
• Stop motion does not work on creel and on warping drum as a result broken ends are not traceable for knotting.
• Chain breakages
• If frictional drum should not be kept in a polished state, then thermal damages occur due to abrasion.
• Brake could be inefficient.
• Sprockets are jammed.
• If comb do not move properly then there is a chance of cutting of comb due to friction with yarn.

Topping & Bottoming
Topping & Bottoming
Bottoming: In this case another dye is applied before dyeing with indigo.
First the warp sheet is dyed with sulfur and then it is washed and then dyed with indigo.
Topping: In this case the warp sheet is dyed with indigo in start and then it is washed
and then it is dyed with another dye (normally with sulfur).
Bottoming indigo Topping: In this case the warp sheet is firstly dyed
with some...

DENIM DYEING
DENIM DYEING:
The classical jeans were produced out of indigo-dyed Denim fabric. The special character of this fabric only the warp thread is dyed makes
it necessary to carry out dyeing in yarn form. The yarns applied for Denim were exclusively produced on ring spinning machines in former times.
The development of OE (open end) yarns by applying smaller...

SHEDDING SYSTEM
SHEDDING SYSTEM
There are four shedding systems used to provide manipulation to the warp yarns:
Crank Shedding
Cam Shedding
Dobby Shedding
Jacquard Shedding
CRANK SHEDDING:
This is the simplest shedding system. In this system, the crankshaft of the weaving machine provides the harness motion. This system is used only for plain weave and its derivatives.
CAM SHEDDING:
A typical cam system can handle weave patterns with up...

Weaving of denim fabric
WEAVING
INTRODUCTION
The process of producing a fabric by interlacing warp and weft threads is known as weaving. The machine used for weaving is known as weaving machine or loom. Weaving is an art that has been practiced for thousands of years. The earliest application of weaving dates back to the Egyptian civilization. Over the years, both the process as well as the machine has undergone phenomenal changes. As of today,...

Sizing for Denim Weaving
SIZING
Although the quality and characteristics of the warp yarns coming out of the winding, warping and dyeing processes are quite good, they are still not good enough for the weaving process for most of the yarns. The weaving process requires the warp yarns to be strong, smooth and elastic or extensible to certain degree. To achieve these properties on the warp yarns, a protective coating of polymeric film forming...
