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...

Difference between Dyeing and Printing

Image
Difference between Dyeing and Printing: No. Dyeing Printing 1. No localized application. Localized application. 2.   Higher liquor ratio. Less liquor ratio. 3. Thickener is not used. Thickener is used. 4. Color is applied   through solution. Color is applied through paste. 5. Only   one dye solution is used in case of dyeing application. One or more dye is used during the application of printing. 6. Fibers,yarn,fabrics are dyed by applying of dyeing   application. Printing is done on the fabric surface. 7. Perfect design is not needed here. Perfect design is must needed.   Dyeing: Dyeing is the process of imparts colors of textile material through a colorant (dyes and pigments). Colorant: Organic and inorganic materials that can impart color on textile. Dye: Dyes are colored,unsat...
