Textile Winding and Waxing

Winding Tension, Bobbin Formation, Speed and Production

Mar 4, 2014 |

Winding Tension If winding tension is selected properly, the following tensile properties are not affected Tenacity Elongation Work- to- break But excessive tension in winding will deteriarate the above said tensile properties. Characterestics Of Bobbin Formation Stretch Length It is the length of the yarn deposited on the bobbin tube during each chase (one up […more]

Yarn Faults And Clearing

Feb 9, 2014 |

Yarn Faults And Clearing It is still not possible to produce a yarn without faults for various reasons. Stickiness of cotton can contribute to the formation of thick and thin places. Fly liberation in Ringframe department is one of the major reasons for short faults in the yarn because of the fly gets spun into […more]

Overview of Waxing

Feb 9, 2014 |

Overview of Waxing Waxing is the process which is almost exclusively used in all automatic and manual winding machines for yarns which are meant for knitting. This helps to reduce the coefficient of friction of yarns created during knitting process. Extensive tests have shown that the coefficient of friction of waxed yarn is not constant, […more]

Singeing

Feb 9, 2014 |

Singeing Singeing is a process applied to both yarns and fabrics to produce an even surface by burning off projecting fibres, yarn ends, and fuzz. This is accomplished by passing the fibre or yarn over a gas flame or heated copper plates at a speed sufficient to burn away the protruding material without scorching or […more]

Ply Yarns

Feb 9, 2014 |

Ply Yarns For sewing threads as well as for some speciality industrial yarns , it is necessary to ply (to double or fold) the yarns to give them a smoother and less hairy character. Doubling improves the evenness and plying balances torque if carried out correctly and binds some of the hairs on the component […more]

Splicing

Feb 9, 2014 |

Splicing A high degree of yarn quality is impossible through knot, as the knot itself is objectionable due to its physical dimension, appearance and problems during downstream processes. The knots are responsible for 30 to 60% of stoppages in weaving. Splicing is the ultimate method to eliminate yarn faults and problems of knots and piecing. […more]

Bobbin Rejections and Quality Checking for Best Winding

Feb 9, 2014 |

Bobbin Rejections and Quality Checking for Best Winding A bobbin change occurs when yarn on the bobbin is fully exhausted during winding. But if a bobbin is changed with yarn still left on it, we call it ‘Rejected Bobbin’. The quantity of yarn on the bobbin may vary from full bobbin to only few layers […more]

Winding Package Defects

Feb 9, 2014 |

Winding Package Defects Following are Some of the Winding Package Defects which will result in complaints Yarn Waste in the Cones This is due to loose yarn ends that are wound on to the cone Stitch, Drop Over, Web Yarn is visible on the small or on the big side of the cone either across […more]

Types Of Winding

Feb 9, 2014 |

Types Of Winding 1.Drum Winding 2.Precision Winding Drum Winding Drum winding machines rotate the forming package through surface contact with a cylindrical drum , and the yarn is traversed either by an independent traverse, typically by a wing cam or by grooves in the drum. Precision Winding Drum winding systems involves a significant contact between […more]

Overview of Winding

Feb 9, 2014 |

Overview of Winding Winding Ring spinning produces yarn in a package form called cops. Since cops from ringframes are not suitable for further processing, the winding process serves to achieve additional objectives made necessary by the requirements of the subsequent processing stages. Following are the Tasks of Winding Process Extraction of all disturbing yarn faults […more]
