Genetically determined hypertrichosis is uncommon, but several forms of familial hairiness have been described. In some kindreds the unusual hairiness has been generalized, while in others, the hypertrichosis has been confined to a specific site on the body. The purpose of this paper is to report the occurrence of undue hairiness of the elbow regions in members of an Amish family, and to discus...

The twisting process of Sirospunning and Ringspunning was compared and analyzed as to the phenomenon that Sirospunning decreases yarn hairiness. It can be obtained from the analysis of geometrical model that more hairiness is twisted into the yarns and the amount of apparent hairiness is reduced through its special twisting. It can be calculated that when the count is equal Sirospunning can red...

BACKGROUND Functional traits are the primary biotic component driving organism influence on ecosystem functions; in consequence, traits are widely used in ecological research. However, most animal trait-based studies use easy-to-measure characteristics of species that are at best only weakly associated with functions. Animal-mediated pollination is a key ecosystem function and is likely to be i...

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...

Leaf sheath hairiness is a morphological trait associated with various advantages, including tolerance to both abiotic and biotic stresses, thereby increasing yield. Understanding the genetic basis of this trait in barley can therefore improve the agronomic performance of this economically important crop. We scored leaf sheath hairiness in a two-year field trial in 1,420 BC1S3 lines from the wi...

Air drag on yarn and package surfaces affects yarn tension, which in turn affects energy consumption and ends-down in ring spinning. This paper investigates the effects of yarn hairiness on air drag in ring spinning. Theoretical models of skin friction coefficient on the surface of rotating yarn packages were developed. The predicted results were verified with experimental data obtained from co...

It has commonly been considered that women’s preference with regard to male body hair changes over the years according to fashion and is influenced by the media. Experimental evidence, however, is currently lacking. We examined the effect of male torso hairiness on Finnish women’s attractiveness ratings by presenting pictures of male torsos before and after the removal of body hair. We found th...

The extent of morphological variability of endod (Phytolacca dodecandra) sampled from 17 localities in Ethiopia that varied from 1600 to 3000 meters above sea level (m.a.s.l) was investigated using 16 characters. Statistical analyses were performed using leaf hairiness and altitude as categorical variables. Cluster analysis performed using average taxonomic distance matrix revealed the separati...

Yarn hairiness has been an important indication of yarn quality that affects weaving production and fabric appearance. In addition to many dedicated instruments, various image analysis systems have been adopted to measure yarn hairiness for potential values of high accuracy and low cost. However, there is a common problem in acquiring yarn images; that is, hairy fibers protruding beyond the dep...

Yarn hairiness is one of the key parameters influencing the quality of yarn.It is observed that yarn quality has been deduced based on yarn length and diameter only. But these parameters do not provide much information about yarn quality. Thus it is proposed to derive more yarn quality parameters like yarn hairiness, uniformity of yarn and its thickness. In textile industry, image processing is...
