Definition of Pretreatment textile processing
Process pretreatment of textile is all mechanic
and chemistry process to textile materials both
for is made from natural and synthetic fiber
before dyeing, printing and finishing process
,with purpose the process is fluently better
and the result can which as expected.

• As a whole this process consist of desizing
  process, souring and bleaching.

Pretreatment process basically aim to removal all
impurities found on fiber ( especially cellulose)
so that materials have i) degree of white, ii)
absorbent to dyestuff and iii) morevalue of
DP(degree of polymerization) the other purpose
is to get bunches of reaktif blocked previous to
become opened.

The raw material in generally contaning unwanted
matter of fibres and the impurities of fibres.
This impurities is

• Natural impurities is the dirt is emerge
  together with happening of fibres. For example
  fat ,oil wax on cotton, sirisin on silk, suint,
  fat and lanolin on wool.
• Impurities from outside
• Dirt coming from outside and to stick at fiber,
  yarn or fabric , for example oil, ,dust , parts
  of leaf, branch, stains of oil from machine and
  etc.
• The addition of impurities
• The addition material impurities for the fluency
  of process for example oil for anti static
  agent at fibers, starch at warp of yarn, etc.

Suint A natural grease formed from dried
perspiration found in the fleece of sheep, used
as a source of potash.

Preparation of process be done by grey material
before wet process or chemical process.
Preparation of this process consist of opening
and pile up, sewing, and inspection of cloth .
Pile up is working to open cloth of grey which
still in the form of roll tied ,then to put in
orderly heap above palet by horizontaly off
attractively tip oves him with length
sufficiently ( 3 - 4 metre), withdrawal of cloth
back part aim to to water down process writing of
stitching and code or tacking on.
Opening or of unrolling recognized with process
expose of cloth have purpose to open cloth of
rolling form become wide form so that the next
process fluently better,then stacked by cart(
each extension every piece have to be sewed).
Process is doing by Opener or Unrolling machine.

• Description Picture
• Tip of cloth
• Tip of cloth jetty
• Tip of cloth to be sewing
• Palet.

11
Sewing is process of conecting on cloth back part
which is one with other cloth back part.Purpose
of this process is to be above cloth of palet
become one unity so that at the time of process
will not be broken.
CODEFICATION
Codefication is process to give a code at jetty
and the end of grey fabric which have pile up by
using permanent stationery.

• SEWING

12
Inspection of cloth is to checking grey of
fabric which have been sewing as a mean to know
cloth fabric defected, long, wide, dirt, and know
the existence of metal so that cloths to be
processed really ready for processed, and dont
happened trouble during process take place.

• For exmple the manner of writing fabric code

WV I ,S 7500/25 TR,P 250 m,2/4 Grup B Meaning is
WV I the fabric is made from weaving I
machine S type of plait is satin 7500 the
total sheet of yarn of fabric wide 25 pick/cm
or total sheet of yarn per cm TR the warp is
tetoron and the weft is rayon P 250m the long
of fabric is 250 metre
14
To the practice of laboratory needed by
laboratory appliance which almost everything was
made from good glass, so that either its use
and conservancy, need hygiene, correctness and
be carefully.
