Dongguan Heng Xiang Ribbon Limited (www.hengxiang168.com) strive to be and you win, symbiosis, strategic partners before the trip, the more determined to become blended, interwoven fabric of the most influential companies, together with you leap, How common success than the date of determination of elastic stretch bands:! [2014-9-19 9:01:59] total reading [5] times reflect a lot of my friends do not know how to measure the elongation ratio of the elastic band, where small series of elastic bands Determination of the elongation ratio briefly explain: the measured tension-free tape in the natural state in equal shares in the inspection stage, more than 1m away from the ends of the elastic band silk screen, in the middle of any tape marked with a ruler to take some of 10cm apart two points slowly until it is stretched to the limit, the measured distance of the mark, the extension ratio is calculated according to the formula, at intervals of 2m first pull, were measured three times and averaged. I hope the above information on how to introduce the elongation ratio measuring the elastic band can help your business. As a professional manufacturer elastic band elastic band supplier, we sincerely hope that our products can bring you more convenience and save more investment. How to detect the size of the elastic band of elastic bands as clothing materials, particularly suitable for underwear, sportswear, wedding dress, T- shirts and other apparel products. Let's briefly look at how to detect the size of the elastic band: 1, the detection width: in the subject finished, the random band-like, so that the elastic band was seized part of the tension-free natural state decentralization flat, away from the ends of 2m or more elastic bands, with an accuracy of 0.5mm for the ruler to measure the width of the elastic band tightness direct, measured once every 2m, measured at least three times and averaged. 2, the detection length: in the finished product was seized, with a random sample, so that the elastic band in the absence of tension in the natural state, with an accuracy of measuring tools to measure the length of 1mm elastic band. I hope that these elastic band size on detection methods described can be helpful to you.
