Influence of Chenille Yarn Manufacturing
Parameters on Yarn and Upholstery Fabric Abrasion Resistance
Özcan ÖZDEMİR & Erhan Kenan ÇEVEN
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.
Effect of
Chenille Yarn Parameters on Yarn Shrinkage Behavior

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.
