Card feeding is of two types: 1.Lap Feed (Conventional) 2. Chute feed (Modern) (a) Single chute feed system (b) Double chute feed system Advantages of lap feed system 1.Linear density of the lap is very good and easier to maintain (uniformity). 2. The whole installation is very flexible. 3. The deviation of card output will […more]
Types of Textile Carding Machines Hand carders Hand cards are typically square or rectangular paddles manufactured in a variety of sizes from 2 by 2 inches (5.1 cm × 5.1 cm) to 4 by 8 inches (10 cm × 20 cm). The working face of each paddle can be flat or cylindrically curved and wears […more]
Blowroom and Carding Calculations 1. Cleaning Efficiency = trash removed/total trash fed *100 2. Efficiency = tr/tf * 100 = tf-tr/tf * 100 3. Waste = trash + lint 4. Waste Extracted = weight fed * waste% 5. Waste Extracted = weight fed – weight delivered 6. Weight Delivered = weight fed – waste extracted […more]
Basic Terms in Textile Spinning Blow room Lap The Loose strand, roughly parallel, untwisted fiber sheet produced in blow room. Chute feed system It is a system of feeding small tufts of fibers directly from blow room to a series of cards, arranged in a circuit through pneumatic pipe. Sliver The strand of loose, roughly […more]
Staple Yarn Spinning and Filament Yarn Spinning Staple Yarns Staple or spun yarns in other hand are made from short length of fibers. It can be found from natural fibers or can be produced using synthetic as staple filament yarns. As it is short length, staple fibers need to be held together with others in […more]
Project Report to Start a Cotton Ginning Mill 1. Introduction A Cotton Gin (short for cotton engine) is a machine that quickly and easily separates the cotton fibers from the seedpods and the sometimes, sticky seeds, a job previously done by hand. These seeds either used again to grow more cotton or, if badly damaged, […more]
Stone catcher Machine * Removes Stones & heavy sticks from the Raw Cotton. * Saves sharp edges of double roller gins Blades.
Pre-Ginning Cleaning Machine * Effective opening of seed-cotton bolls and separations of trash. * Removal of 60% to 70% immatured seed – cotton bools. * Reduction in trash content level by 20% to 30% in seed -cotton * Significant improvement in ginned cotton qulaity. * Robust machine design and less maintenance * Less Electric power […more]
Air Separator Machine This machine separates the air & cotton in pneumatic cotton conveying system. * Effective separations of seed – cotton / cotton lint. * Removal of very short fibers and micro dust. * Improvement in appearance of seed – cotton / cotton lint. * Less electric power requirement.
Lint Cleaner Machine * Effective opening of ginned cotton lint and separation of trash particles * Remove of seed – coats, leafy matters, micro dust, very short fibers and small sized fiber cluster from the ginned cotton lint by about 30% to 45% * Cleaning capacity of 1500 kg of cotton lint per hour. * […more]
