Unit V

Suggested Micro Project / Assignment

Micro project

Identify dyeing faults: Visit nearby industries and collect dyed samples of faulty dyeing and find remedies to rectify the same. Present your report.
Lab to bulk dyeing: Collect any two cotton dyed samples from industry with their recipe and produce same results in laboratory on OBBD machine by changing appropriate recipe. Correlate the results and present.
Water consumption: Visit any textile dye house. Collect information of any two dyeing machines for their water consumption. Calculate the quantity of water consumption per kg of fabric. Present your report.
Shade matching: Collect any one dyed sample from nearby dye house. Using any class of dye match the shade in the laboratory. Present your matched samples with recipe.
Fastness properties: Collect any one dyed sample from the nearby dye house and assess its fastness to washing, rubbing and perspiration. Present your ratings.

Assignment

Calculate dye and chemical cost: Collect a dyeing recipe, cost of dyes and chemicals used for any two dyeing methods from a nearby process house and calculate dyeing cost. Prepare and submit the results.
Library/ internet survey: Identify developments in dyes, dyeing machines and dyeing process used for cellulosic dyeing. Prepare and submit the report.
Safety in process house: Collect information on safety precautions of various chemicals and machinery used in the process house. Prepare and submit the report.
