Abstract

 

 

In this study, forty-eight different chenille yarns are produced on a chenille machine using a range of material types, twists, and gauges. In the first group, 4 Nm count chenille yarns are produced with six different pile materials, two different twists, and two different gauges. In the second group, 6 Nm count chenille yarns are produced with the same machine and material parameters. In order to measure the performance of chenille yarns, their abrasion resistance is measured with a chenille yarn abrasion device, and the abrasion resistance of upholstery fabrics made from these yarns used as filling is measured with a Martindale wear and abrasion tester. The results of pile loss are evaluated according to material type, twist, and pile length of the chenille yarns. Clearly, there is an improvement in abrasion resistance with increasing twist, gauge (pile length), and the use of natural fibers as pile materials, which may be due to increasing frictional behavior between the pile and lock yarns.

Abstract

 

The effects of chenille yarn properties-pile material type, pile length, and twist level-on the boiling shrinkage behavior of chenille yarns are examined in this study. Different chenille yarns are produced on a chenille machine using a range of pile material types, twist levels, and pile lengths. Nm 4 and Nm 6 count chenille yarns are produced from different pile materials of viscose, acrylic (0.9 dtex), acrylic (1.3 dtex), combed cotton, carded cotton, and open-end cotton, in two different pile lengths of 0.7 and 1.0 mm and two different twist levels of 700 and 850 T/m. The results indicate that pile material types, pile lengths, and twist levels have significant effects on the boiling shrinkage of chenille yarns.

 

Properties and Manufacture of Chenille Yarns

Abstract

 

Chenille yarns are a kind of fancy yarns traditionally used in the manufacture of furnishing fabrics and trimmings, fashion knitwear, and as decorative threads in many types of broad and narrow fabrics. Chenille yarn consists of short lengths of spun yarn or filament that are held together by two ends of highly twisted fine strong yarn. The short lengths are called the pile and the highly twisted yarns are called the core. The result is a yarn with velvet like or pile surface. Chenille is a difficult yarn to manufacture, requiring great care in production. Due to the nature of chenille's pile direction, pile completeness (or lack of missing pile), and pile loss, great care must be taken in converting chenille into final articles.
