  1. Operation Pretreatment Process of Textile Pretreatment Process of Textile Materials

  2. 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.

  3. 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.

  4. 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.

  9. 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. Teknologi dan Rekayasa

  11. 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 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.

  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 don’t happened trouble during process take place.

  13. 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 For exmple the manner of writing fabric code

  14. THE KINDS OF APPLIANCE LABORATORY 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.
