Abstract:
Prediction of sewing thread consumption requires an accurate method of calculation
since it relates to the cost of manufacturing and distribution of apparel products.
Previous researchers highlighted problems in existing thread consumption
calculation methods; i.e. limitations in existing formulae which cause inaccurate
predictions of thread amount needed for sewing operations. The existing methods
of consumption calculations exhibit significant error percentages due to the
ignorance of important parameters which affect on thread consumption. This paper
investigates on correlation of thread tension to thread consumption of lock-stitch
301 and chain-stitch 401. The existing thread consumption formulae are optimized
by considering a new parameter; thread tension, using regression analysis and
geometrical modeling techniques. For the chain-stitch 401, results indicate that the
thread tension significantly affects in determination of the thread consumption. The
error analysis of proposed formulae was performed to indicate that the proposed
formulae more accurate compared to the available methods of predicting sewing
thread consumption. In addition, there are combined effects of thread tensions
together with parameters such as fabric thickness and stitch density which
determines accurate consumption values considering the properties of the stitch. In
comparison, inclusion of the proposed thread tension variable depicts reduction in
error percentages, so that the proposed formulae are expected to be a better
approach to calculate thread consumption of lock-stitch 301 and chain-stitch 401.
