price of technologically advanced machine is comparatively very high. But this machine gives consistent quality work which is desired for manufacturing of shirt as pocket attaching is a critical operation. While considering complete sewing line modernisation it is observed that SAM value of 31 minutes can be reduced to 26.02 minutes by installing advanced machinery in the above four operations. If manufacturing shirts in 8 hours shift requires certain amount of investment in basic level of technology, the same would be around 14.17 per cent more (as compared to the investment in basic level of technology) in advanced sewing technology. Further, the annual labour charges for sewing room will be approximately 15 per cent less in basic level of technology. So there is very little benefit of adopting advanced technologies in the sewing room. Conclusion While it is clear that the shirt is a commodity item, there are forced and unforced variations in style, and thus in operations and work content. An appropriate selection of technology is very important to get higher return on capital employed. Contrary to the popular belief of sewing button and buttonholes after completion of the sewing of the shirt, it is also noticed that the majority of shirt manufacturers are sewing buttons and buttonholes in collars, cuffs and front plackets in parts preparation stage itself, resulting in substantial reduction in overall work content due to savings in handling time. As indicated above that advanced technology in sewing (in selected operations) does not result in an attractive ROI, this may be an indication why there is not much technology in use in sewing room of leading shirt manufacturers? This article only explores the sewing room operations; there is potential for improvement in pre-sewing and post-sewing operations too. www.apparelresources.com | December 2018 | Apparel Online Bangladesh 49
