“…All studies showed that fabric mechanical behaviour depends on finishing parameters (kind of finishing, temperature, time) and seaming parameters. The most studied seaming parameters are the needle heating, the needle point shape and the needle surface treatment [3,5,7,10]. We have studied the effect of finishing on fabric mechanical properties and its influence on seam quality.…”

“…Needle temperature increased more for dyed and finished fabrics than for fabrics that are only bleached. In addition, the types of finishing treatment generated different heating behaviours [7].…”

“…The influence of the material being sewn is that fabrics with synthetic components generate more heat than those without, and as the number of fabric plies increases, the needle becomes hotter [7]. The needle heating damages the fabric by making holes, especially for fabrics containing thermoplastic fibres.…”

The purpose of this work is to investigate the performance of seams after successive treatments applied to a woven fabric. Performance of seams was assessed by their load/elongation behaviour. Successive chemical treatments such as desizing, scouring, bleaching and dyeing followed by a type of mechanical finishing known as sueding were applied to the fabrics. After each treatment, mechanical tests performed on seamed and non-seamed fabrics. Three factors were studied: the treatment type, the stitch density (number of stitches per centimetre) and the direction (weft or warp direction) of the seam. Three responses were measured: the seam elongation at break, the seam breaking force and the seam efficiency. This study shows that the qualities of the seams depend on the fabric modifications generated by the chemical and/or mechanical treatment. Furthermore, the rigidity of the fabrics was shown to vary with dyeing and colour class. The initial fabric properties before stitching have an important impact on the behaviour of the seams. This work shows that it is more useful to study the yield point (elastic phase) than the rupture point of the load/elongation curves; as stitched fabrics are worn, the elastic phase (fabric recovery) is more important than the plastic phase. The yield point of seams characterizes the real limit of use of stitched fabrics better. In this work we have used a complete-factorial plan to study interactions between factors affecting the seam breaking force, elongation at break and efficiency; and found the most significant interactions between the factors that affect the seam breakage.

In this article two methods are used to measure the temperature of needle eye during the high speed of sewing and the results are compared for calculating the precision in the measurement,Needle heatup is a big issue for apparel industry especially for automobile industry seat covers where a lot of synthetic materials are used which get damaged by needle heat at high speed of sewing machine,in this article thermocamera and thermocouple are used to calculate the precise temperature of needle eye and then 100% polyester 35x3 Tex thread is taken for sewing,the lockstitch sewing machine is run at 1000rpm,2000rpm and 3000rpm respectively and the both methods are used to obtain the accurate needle temperature and finally thread tensile properties the article is very helpful in predicting the exact temperature of needle in lock stitch machine at different stages of sewing process.Keywords-needle eye heat,needle temperature of sewing machine

“…Experiments are in progress along this line, the details of which will be published in the near future. [ 1,2,[6][7][8]12] have an important effect on needle temperature and forces opposing needle penetration. However, the relationship between fabric parameters and needle temperature or forces opposing needle penetration has not been determined, and some information on this subject is given here.…”
