Yarns Performance Quality characteristics

Yarn characteristics and performance are identified and measured so that an appropriate yarn is used in the fabric and product. Yarns Performance Quality characteristics yarn strength is very good determined by quantifying the load that breaks a yarn and the percent of elongation at that load. Tolerances or variations allowed in a yarn of a given type are measured so that consistency in performance and appearance can be evaluated.

Yarns quality is a very important factor because related to the quality of the result fabrics goods. Yarns quality refers to several reasons such as yarns strength and thin quality spots in yarns that are weaker and likely to break when the yarn is under stress. These thin spots, or nips, create thin, very weak areas in fabrics or unacceptable variations in fabrics appearance.

Yarns Performance Quality characteristics Yarns Must be Strong

Yarns must be strong enough to withstand the stresses of looms and knitting machines for Yarns must be strong. Strength demands on yarns depend on the structure of the fabric and its end use. Stress can be substantial during fabric production; yarn breaks are costly to repair and decrease fabric quality. Fabric producers very demand so much high quality yarn and uniformity of yarn characteristics at so much low prices. Yarn producers are responding to these demands by incorporating online systems to detect yarn defects and fix them as soon as they begin to develop in the spinning process.

Many factors determine the good quality of a yarn. Best quality yarns have more similar fibers, very good tighter twist, and are more very good regular than lower quality yarns. High-quality yarns are strong enough to withstand additional processing (warping, weaving, knitting, etc.). So much high quality yarn is regular in structure with few place thin spots. They are comparatively free of unacceptable for neps and hairiness.

There are neps small knot of entangled fibers, which is may be immature fibers don’t get Yarns must be strong. Many dead yarns and consequently create problems by not accepting dyeing. Neps are may be create thick and thin spots place on yarns or uncolored flecks in finished fabrics. Hairiness are describes very excessive fibers ends on the yarn surface area. Under the picture are show differences in yarn hairiness outstanding to spinning technique.

Yarn Hairiness

Hairy yarns must be will be create problems in fabric or in consumer when he will use because they tend to be more sensitive to abrasion. Good-quality yarns facilitate subsequent dyeing and finishing steps. Their appearance and performance make the finished material suitable for the end use and target market.
