A staple fiber is a textile fiber of discrete length. The opposite is a filament fiber, which comes in continuous lengths. Staple length is a characteristic fiber length of a sample of staple fibers. It is an essential criterion in yarn spinning, and aids in cohesion and twisting. Compared to synthetic fibers, natural fibers tend to have ...
The staple length of the wool is the length of the staple, and highly correlated with mean fibre length in the top (hauteur). Staple length generally determines the end use of wool, that is, whether it will be used in weaving or knitting. The longer wools, generally around 51 mm and longer and called combing types, are processed to worsted yarn.
Staple length is a term referring to the average length of a group of fibers of any composition. Short staple cotton fibers produce carded yarns that are generally irregular and have protruding hairs, hence a low yarn quality. Long-staple fibers contribute to better spinnability and strength, delivering regular yarns of superior quality.
A heavy duty office staple might be designated as F1667 STFCC-04: ST indicates staple, FC indicates flat top crown, C indicates cohered (joined into a strip), and 04 is the dash number for a staple with a length of 0.250 inch (6 mm), a leg thickness of 0.020 inch (500 μm), a leg width of 0.030 inch (800 μm), and a crown width of 0.500 inch ...
Cotton traders use many systems to classify the quality of cotton fiber. One of the most significant distinctions is "staple length", length of the individual fibers. Traditionally, cultivars of Gossypium barbadense fall into the "long-staple" category. The term extra-long-staple (ELS) first came into use in 1907.
l/m = 1693 × l m /Nec × m/kg, where l/m is the yarn length in metres, l m /Nec is the English cotton count and m/kg is the yarn weight in kilograms. The following length units are defined. Bundle: usually 10 lb (4.5 kg) Thread: a length of 54 in (1.4 m)—the circumference of a warp beam; Lea: 120 yd (110 m) Hank: a length of 7 leas or 840 yd ...
Cotton fibres differ in terms of staple length and other physical characteristics; this is an inherent feature. [5] Bale management, also known as "bale mixing," is the process of analysing, classifying, and then blending fibres from various bales [which also includes the bales received from other stations] according to their fibre properties ...
The twist is never allowed to get between the active and the passive hand. When the active hand is back at the distance of the staple length from the passive, the whole technique repeats. [1] In backwards short draw, the hand closest to the wheel is the passive hand.
