INTRODUCTION
The textile industry is primarily concerned with the design and
production of yarn, cloth, clothing, and their distribution.
Textile industry are also that manufacture raw product for cloth
manufactured companies and industries.
Textile industry can be classified into three categories cotton , woolen
and synthetic fiber which are to be depending upon the raw material
used in it.
Indian Textile Industry
India contributes to about 25% share in the world trade of cotton yarn.
I dia, the worlds third-largest producer of cotton and second-largest
producer of cotton yarns and textiles, is poised to play an increasingly
important role in global cotton and textile markets
The ready ade gar e t se tor is the iggest seg e t i the I dias
textile export basket contributing over 46% of the total textile exports.
Exports have grown at an average of 9.47% pa over the last decade.

SPINNING PROCESS
Spinning is a major part of the textile
industry. It is part of the textile
manufacturing process where three
types of fiber are converted into yarn,
then fabrics, which undergo finishing
processes such as bleaching to
become textiles. The textiles are then
fabricated into clothes or other
products.
WEAVING PROCESS
Weaving is a method of textile
production in which two distinct sets
of yarn or threads are interlapped at
right angles. The longitudinal threads
are called the warp and the lateral
threads are the weft or filling.

DYEING PROCESS
Dyeing is the process of adding color to
textile products like fibers, yarns, and
fabrics. Dyeing is normally done in a
special solution containing dyes and
particular chemical material. After
dyeing, dye molecules have uncut
chemical bond with fiber molecules.
The temperature and time controlling
are two key factors in dyeing. There are
mainly two classes of dye, natural and
man-made.

PRINTING PROCESS
Textile Printing is the process of applying
color to fabric in definite patterns or
designs. In properly printed fabrics the
color is bonded with the fiber, so as to
resist washing and friction. Textile printing
is related to dyeing but in dyeing properly
the whole fabric is uniformly covered with
one color, whereas in printing one or more
color's are applied to it in certain parts
only, and in sharply defined patterns.

WASTE WATER AND ITS
TREATMENT IN TEXTILE
INDUSTRY
Textile wastewater includes a large variety of dyes and chemical additions
that make the environmental challenge for textile industry not only as
liquid waste but also in its chemical composition.
Main pollution in textile wastewater come from dyeing and finishing
processes.
These processes require the input of a wide range of chemicals and
dyestuffs, which generally are organic compounds of complex structure.
Water is used as the principal medium to apply dyes and various chemicals
for finishes.
Because all of them are not contained in the final product, became waste
and caused disposal problems.
Major pollutants in textile wastewaters are high suspended solids,
chemical oxygen demand, heat, colour, acidity, and other soluble
substances.
Substances which need to be removed from textile wastewater are mainly
COD,
BOD,
nitrogen,
heavy
metals
and
dyestuffs1,2.
