...Darja Zˇunicˇ‐Lojen; Jelka Gersˇak The quality of sewing threads, as defined by their mechanical and physical properties, is connected with seam quality and seam strength. Seam quality and seam appearance depend mainly on the following sewing thread properties: bending properties, dimensional...

...Gojko Nikolic´; Zˇeljko Sˇomođi; Diana Franulic´ Sˇaric´ The proposed solution for increased automation in clothing production by freezing the textile involves sewing operations in frozen state. The realistic applicability of such technology could be limited, amongst other issues, by the possible...

...Isao Ajiki; Ron Postle The viscoelastic properties of the sewing thread before and after loading in the sewing process were investigated. Sewing threads are subjected to dynamic tension and friction in the sewing process. In order to compare polyester, cotton and silk sewing threads, the fineness...

...Shu‐Hwa Lin; Mary Ann Moore; Doris H. Kincade; Carol Avery The purpose of this study was to explore the dimensions of apparel manufacturing strategy (i.e. cost, quality, flexibility, delivery time) and their relationship to style and sewing systems. U.S. apparel producers are seeking strategies...

...Qinwen Li; Evangelos Liasi; Dan Simon; Ruxu Du This is the second part of our study on needle heating in heavy industrial sewing. In this part, a finite element analysis (FEA) model is presented. Using a commercial FEA software system, ANSYS, the needle is modeled by a number of 3D bar elements...

...Dubravko Rogale; Zvonko Dragčevic´; Anica Hursa An investigation is presented of the impact of mechanical auxiliary devices on sewing‐machines upon the processing parameters of sewing operations. Processing parameters are investigated at an ergonomically designed workplace, on a modern sewing...

... the sewing process. This contribution presents the influence of pre‐tension in a defined area on the tensile force in important phases of the stitch formation process. In addition the influence of the stitch velocity on tensile force was investigated. On the basis of statistic analysis it was ascertained...

...Qinwen Li; Evangelos Liasi; Hui‐Jun Zou; R. Du In heavy industrial sewing, needle heating has become a serious problem that limits the further increase of the sewing speed, and hence the productivity. The high temperature in the needle can degrade the strength of the thread. At the same, it may...

...Jerzy Zajaczkowski Considers the mathematical modelling of sewing machines. The machine with a rotary hook and with a feed mechanism driven by two triangle cams is studied. The behaviour of the system is described by a set of non‐linear autonomous ordinary differential equations. It is shown...

... as a whole. Manufacturing Management Sewing © MCB UP Limited 2000 Upper level executives in apparel and sewn products companies in the USA are facing a number of challenges in order to compete effectively in global markets. Both the retailers and the ultimate consumers are demanding...

...Evangelos Liasi; Ruxu Du; Dan Simon; Jasmina Bujas‐Dimitrejevic; Frank Liburdi This paper presents an experimental study on needle heating in sewing heavy materials such as upholstery fabrics. In the experiments, infrared (IR) radiometry, high speed line scanning IR radiometry, and high speed IR...

...Eric Mallet; Ruxu Du Sewing is one of the most commonly used manufacturing processes in the world. Millions of parts are sewn every day ranging from cloths, shoes, furniture, to automobile seat covers. However, it is also one of the least understood processes. In fact, according to literature...

..., the sideview camera is 2.54m away from the working area, 75cm above the floor level (at the height of the operative’s abdomen), while the upper camera is 1.89m above the working area, and the central axis is above the sewing needle position. Camera positions are not altered during recording, and automatic...

...Dubravko Rogale; Zvonko Dragčević A measuring system for automatic process parameter acquisition in garment sewing operations has been presented. The measuring equipment is based upon the usage of a very powerful portable notebook IBM compatible personal computer, equipped with an AD converter...

...G. Sundaresan; K.R. Salhotra; P.K. Hari The mechanism of strength reduction of sewing threads has been discussed in Part I of this paper. The effect of fabric tightness and certain thread properties like its size, coefficient of yarn‐metal friction, twist direction, number of piles, type of fibre...

...G. Sundaresan; P.K. Hari; K.R. Salhotra Reports on investigations into the mechanism of sewing thread strength reduction. Results indicate that structural damage, namely, structural openness and pull‐out of fibre ends from the surface are the major cause of strength reduction and that the fibre...
