The web-sites of sewing equipment producers were analyzed to see the availability of blindstitch sewing machines in the world's market. 68 manufacturers from 143 researched companies produce one or more types of blindstitch sewing machines. The blindstitch machines of stitch 103 are manufactured the most often. The machines of stitch class 300 are developed for specifi c applications manufacturing men suits. The companies Strobel and Maier are most wellknown blindstitch machine manufacturers. The company Strobel has widest off er of class 300 blindstith machines. The company Maier produces sewing machines for industrially manufactured and tailored clothing, as well as, for manufacturing home and technical textile goods.

They are not widely used in garment manufacturing generally, however are must machinery in men suit production. Web-sites of sewing equipment producers were researched to find out the availability of hand stitch sewing machines in the world market. It was found that only 21 companies from researched 143 are manufacturing hand stitch sewing machines. 11 producers sell real hand stitch machines, from them, AFM Reece and Juki develop machines with double pointed needle. 16 producers offer fake/imitation hand stitch machines which create hand stitches only on one material side. The machines use different kind of motors, can be equipped with thread trimming, presser foot lifting backtacking and other advanced mechanisms.

Stabilitatea dimensională a fost analizată prin metoda FAST 4. Diferite probe au fost comparate prin intermediul mai multor indicatori. Rezultatele arată că cea mai stabilă variantă tricotată, vopsită este din:

It is kept fixed during all its very changeable manufacturing process, thereby increasing pre- and post-consumer fabric wastes. To improve the situation the final values of construction parameters which influence fabric use efficiency should be determined for every unique production order only in the garment manufacturing process. Four garment styles were tested to see how light changes in their width and length influence fabric use efficiency. Even minimal reduction of these parameters can give noticeable fabric savings. Different values of these parameters create slightly different shapes of pattern pieces, and with it, give a huge number of new possibilities to create more efficient production markers. The authors found a way how to make the garment designing process more efficient, as well as, to create a “virtual bridge” between garment designing and the manufacturing phase. Both improvements could gi...

The purpose of this paper is to analyse the impact of clothing insulation on the heat transfer. The measurements were carried out on commercially 1x1 RIB knitted fabrics used for the production of next-to-skin shirts. The one group of samples are made from 100% cotton yarn and another with 96% cotton and 4%lycra. It is noticed that knitted material composition affected the change in heat resistance. Also, this paper presents and verifies the correlation between the measured values of thermal resistance (Rct) and the knitwear thickness (dpl), the covering factor (K), the porosity of the twists (e) and the surface coefficient (dp). Based on these results, a mathematical model for calculating thermal resistance is proposed. Comparing the results obtained with the proposed equation and the measured results, we can see that the dev...

The used samples of raw knitwear are made from 100% cotton yarn with different liner densities of 19, 17, 15 and 13 tex. Dimensional stability of these samples was analyzed by FAST 4. The results show that the most stable knitwear is made of 100 % cotton yarn with the linear density 19 tex.The values of the tightness factor in the dry relaxation stood at 14, 93, 15, 14under wet,16,32 under total and 16,20 under air conditioned conditions. The knitwear with the highest values of dimensional instability is a raw knitted fabric made of 100% CO, and the yarn with the linear density of 13 tex. The values of the tightness factor in the dry relaxation stood at 16,20 under wet, 15,14 under total and 12,53 under air conditioned conditions.
