  5. SOUTHEAST UNIVERSITY Department of textile engineering Introduction Fabric Faults/Defects: Fabric Faults/Defects: Common Defects of Fabrics during manufacturing process includes back fabric seam impression, birds eye, bowing, broken colour pattern, colour out, colour seamrs, crease mark, drop stitching, dye streak in printing, hole, jerk in, knots, mixed yarn, mottled, needle line, open reed, pin holes, press off etc. Fabric Faults are two types 1. Knitting Faults. 2. Weaving Faults. December 28, 2013 5 AKH Group and Micro Fibre

  6. SOUTHEAST UNIVERSITY Department of textile engineering Knitting Faults: A defect in the knitted fabric is an abnormality, which spoils the aesthetics i.e. the clean & uniform appearance of the fabric & effects the performance parameters, like; dimensional stability etc. There are various types of defects, which occur in the Knitted fabrics of all types, caused by a variety of reasons. The same type of defects may occur in the fabric, due to a variety of different causes e.g. Drop Stitches, Spirality. December 28, 2013 6 AKH Group and Micro Fibre

  7. SOUTHEAST UNIVERSITY Department of textile engineering Garments Faults/Defects: Garments Faults/Defects: Garments Defects are classified within the following categories: Critical Defect: A serious defect that can cause harm or injury to the user and/or result in a hazardous condition. Major defects: A defect that falls to meet the mandatory regulations directly affecting the usability, stability, safety and value of the merchandise or as specified by customer buyer are considered as major defects and are generally non repairable for example fabric hole, shading among panel, wrong measurement, foreign yarn, dye patches etc. Minor Defects: A defect that does not adversely affect the usability of the product but does consists of a deviation from the original sample, and may affect the sale of the product. Some of these defects are due to workmanship December 28, 2013 7 AKH Group and Micro Fibre

  8. SOUTHEAST UNIVERSITY Department of textile engineering Knitting Faults Causes & its Remedies Faults name Causes Remedy 1. Barre Caused by mixing yarn on feed into machine.

Needle Line Caused by broken needle forming distorted stitches Replace the needle December 28, 2013 9 AKH Group and Micro Fibre

  10. SOUTHEAST UNIVERSITY Department of textile engineering Faults name Causes Remedy 6. Runner Usually caused by broken needle. Change the needle. 7. Slub (Knit fabric) Usually caused by a thick or heavy place in yarn Replace the yarn cone to a more uniform yarn cone. December 28, 2013 10 AKH Group and Micro Fibre

  11. SOUTHEAST UNIVERSITY Department of textile engineering Dyeing, printing and finishing faults Dyeing, printing and finishing faults Causes and Its remedy Causes and Its remedy Classification of Defects  Major Defect • A defect that, if conspicuous on the finished product, would cause the item to be a second. (A "second" is a garment with a conspicuous defect that affects the salability or serviceability of the item.  Minor Defect • A defect is defined as minor Defect that is not likely to reduce the Usability of the product, but nevertheless may negatively influence the sales. • The minor defects can be untrimmed thread-ends, slight dirt in a non- noticeable zone which can be removed, etc December 28, 2013 11 AKH Group and Micro Fibre

  18. SOUTHEAST UNIVERSITY Department of textile engineering Metal Detection Machine: Metal Detection machine is a machine which is detected the metal in the Garments. When the Garments were full completed, then it is passes throw the finishing section. Then the Garments were packaging and it is send the final inspection. The final inspection process is Metal Detection. The packed Garments were passes throw the Metal Detection machine. When the machine was found the metals, then the red button is on. Many metals such as, Pin, Needle, or any other metals. December 28, 2013 18 AKH Group and Micro Fibre

  19. SOUTHEAST UNIVERSITY Department of textile engineering Conclusion Conclusion In Bangladesh the maximum dyeing industry are knit dyeing Industry. So these kinds of industries are often suffering by these Faults which tend to not fulfill the target of production. As a result the production capacity of these industries falls significantly. These are the common faults which I have tried to find out the causes & their Remedies against them. December 28, 2013 19 AKH Group and Micro Fibre
