Types of Textile Spinning Card Feeding

Mar 28, 2016 |

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]

Spinning Calculations – Blowroom and Carding

Mar 26, 2016 |

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]

Spinning Process of Staple Yarns and Filament Yarns

Mar 26, 2016 |

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]

Yarn Conditioning

Feb 8, 2014 |

Yarn Conditioning Moisture in atmosphere has a great impact on the physical properties of textile fibres and yarns.Relative humidity and temperature will decide the amount of moisure in the atmosphere. High relative humidity in different departments of spinning is not desirable. It will result in major problems. But on the otherhand, a high degree of […more]

Linear Programming in Textiles

Feb 8, 2014 |

Linear Programming Linear programming is a quantitative tool for optimal allocation of limited resources amongst competing activities. It is perhaps the most popular amongst OPERATIONS RESEARCH techniques and has found application in several functional areas of business- production, finance, marketing, distribution, advertising and so forth. Any resource allocation problem is characterised by specification of an […more]
