Yarn structure - properties relationship
نویسنده
چکیده
Yarn structure and its relationship with the properties have attracted many researchers and scientists. This has resulted in a large number of published research works scattered in many places. The importance of this subject has increased due to the need of yarn with best possible quality at optimum cost. Also, the diversification of textiles in various products, such as technical textiles, where performance is the main criteria, necessitated better yarn engineering. An attempt has been made to analyse the study reported in this subject area.

Redistribution of Fibers in the Structure of Hollow Ring Spun Yarn
Core yarn was spun by introducing a PVA multifilament as the core through the yarn forming zone of a ring spinning frame and viscose fibers as the sheath containing tracer fibers. The water soluble PVA multifilament was extracted from the yarn structure. Then internal structure and properties of the hollow ring yarn was assessed and compared with those of typical ring yarns. Also, two plain fab...

متن کاملCotton Yarn Engineering Via Fuzzy Least Squares Regression
Modeling of yarn and fiber properties has been a popular topic in the field of textile engineering in recent decades. The common method for fitting models has been to use classical regression analysis, based on the assumptions of data crispness and deterministic relations among variables. However, in modeling practical systems such as cotton spinning, the above assumptions may not hold true. Pr...
متن کاملYarn tenacity modeling using artificial neural networks and development of a decision support system based on genetic algorithms
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...
