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 fibres in the slivers. 2. To make them lie in a manner parallel to their

Relation between Moisture regain and Moisture content

Relation between Moisture regain and Moisture content: Moisture regain   Moisture regain is defined as the weight of water in a material as a percentage of the oven dry weight.   Let,  Oven dry weight of a material = D   Weight of water in this material = W                                      W   Moisture regain, R   =   ……   X 100 %                             …….(A)                                      D Moisture content:   Moisture content is defined as the weight of water in a material express as a percentage of the total weight of the material.                                          W   Moisture content, C   =   ………..   X 100 %       ……………(B)                                       W+D   From equation (1) we get,            W   D =   ……   X 100            R   Putting the value of D in equation (B) we get,                            W   C =   …………………………    X 100            W + { (W/R) X 100}                         W   =>  C =   …………………
