The influence of different experimental conditions on the thermal comfort behavior of polyester-viscose and polyester-cotton ring and MJS yarn fabrics has been studied. The results show that the yarn structure and the fibre cross-sectional shape have a large influence on improving the thermal comfort of woven fabrics. The fabrics made from MJS yarns perform better than those of the ring yarn fa...

This study is focused on the hairiness of worsted wool yarns and how it affects the pilling propensity of knitted wool fabrics. Conventional worsted ring spun yarns are compared with comparable Solospun yarns and yarns modified with a hairiness reducing air nozzle in the winding process (JetWind). Measurements of yarn hairiness (S3) on the Zweigle G565 hairiness meter shows a reduction in the S...

The kinetics of wicking of liquid droplets into yarns was studied by a computerized imaging system. A new method is suggested for characterization of the yarn structure by monitoring the droplet absorption. The method is based on the comparative analysis of the time needed for the droplet disappearance as a function of the droplet volume for various yarns. A mathematical model is developed for ...

The influence of dyeing and spinning on the characteristics of cotton fibers and its impact on the properties of cotton mélange yarn has been investigated. Grey cotton fibers with mean fiber length and fineness of 29 mm and 4.2 micronair were pre-treated and dyed. Three ring yarns were spun from 100 % grey cotton (R.R.Y), 50-50 % blend of dyed and grey cotton (M.R.Y) and 100 % dyed cotton fiber...

Yarn tenacity is one of the most important properties in yarn production. This paper addresses modeling of yarn tenacity as well as optimally determining the amounts of the effective inputs to produce yarn with desired tenacity. The artificial neural network is used as a suitable structure for tenacity modeling of cotton yarn with 30 Ne. As the first step for modeling, the empirical data is col...

Globalization has profound effects on the texti le industry, including yarn production. These effects are not only evident in shifts in the geographical bases of production but also in the 'drivers' for manufacturing. This means that yarn producers are expected not only to produce higher quality yarns on much shorter lead times, but must also be competitive on prices i n order to survive. A mod...

This paper is related to textile industry especially to Yarn manufacturing process. Textile is one of the biggest manufacturing industries in India.Defects rate of product plays a very important role for the improvement of yield and financial conditions of any company. Actually defects rate causes a direct effect on the profit margin of the product and decrease the quality cost during the manuf...

Spyn is a system for knitters to record, recall, and share information surrounding the process of handcraft. Using the yarn as a timeline of a knit's creation, Spyn allows knitters to associate digital annotations to knit yarn. The current prototype uses patterns of infrared ink printed on yarn in combination with computer vision techniques to associate locations in knit fabric with audio and v...

Physical properties of cotton yarns are affected by the characteristics of cotton fibers such as fineness, length, maturity and strength. This relationship has been worked out by means of multivariable regression and stepwise method for an open-end spun (NeC 20) cotton yarn. Moreover, with the help of linear programming, it was made possible to determine the percentage of different cottons in t...
