Study on gearing diagram of a Draw frame Machine.

      YARN MANUFACTURING   TECHNOLOGY LAB-2 Experiment:1 EXP. NAME: Study on gearing diagram of a Drawframe Machine. Introduction /Theory: Drawframe  is a machine for combining and drawing slivers of a textile fiber (as of hemp for rope manufacture or cotton for spinning). Drawing  is the operation by which slivers are blended, doubled and leveled. In short staple spinning the term is only applied to the process at a It is a process of yarn manufacturing in which the sliver is elongated when passes through pairs of rollers, each pair moving faster than the previous one.This permits combination of several slivers. These slivers are drawn and elongated to straighten and create greater uniformity.There are two types of draw frame 1.     Draw frame -1/Pre-comb drawing/Breaker draw frame 2.     Draw frame -2/Post-comb drawing/Finisher draw frame Objectives of Draw Frame: 1. To straighten the fibre...

Introduction to Polymer and Macromolecule(VIVA question for textile)

Introduction to Polymer and Macromolecule (VIVA question and Details) Mer –   The repeating unit in a polymer chain Monomer –   A single mer unit (n=1) Polymer –   Many mer-units along a chain (n=103 or more) Degree of Polymerization –   The average number of mer-units in a chain. POLYMER : Polymer is a type of macromolecule consist by covalent bond of a large number of repeating number. Polymer means many monomer. Monomer: A monomer is a molecule that is able to bond in long chains. Degree Of Polymerization: It is a average number of repeating number in a macromolecule. The importance of polymer science to study for Textile Engineering . 1.Textile fibers are polymeric substance. 2.Size materials are polymer(used in weaving). 3.Printing thickeners are polymer. 4.Binders and fixed used in coloration with pigments are also polymer. 5.Polymers are also used as wet processing. Macromolecule: A macromo...
