The Effect of the Short Fibers in a Cotton on Its Processing Efficiency and Product Quality

Abstract

By differentially ginning a single lot of Acala 44 cotton, various short fiber content levels were obtained. Yarns produced from these cottons showed the effects of increases in short fiber content; namely, reduced strength, elongation, and appearance grade. The twist required for maximum strength was found to be largely unaffected by changes in short fiber content, except for a medium yarn number for which a relationship was demonstrated. A graph showing the close relationship between the percentage of fibers less than 3/8 in. and those less than 1/2 in., calculated for a wide number of cottons, is included. Spinning efficiency is shown to be adversely affected by changes in short fiber content.

The Optimum Twist Factor for Jute Yarns of Various Sizes and Fiber Qualities, and Tex-Tenacity Relations at Different Twist Factors

“…For cottoii yarns, although tlie optimum twist factor remains constant over a wide range of yarn sizes [5, S, 121 and fiber lengths [12], it iiicreases slightly with fiber coarseness [5, 7, S]. I n tlie case of jute, however, the h i t s of the optimuni twist factor, i.e., 24 to 26, possibly cover the effects of small variation iii coarseiiess of filaments though they are of branched nature.…”

The Effect of the Short Fibers in a Cotton on Its Processing Efficiency and Product Quality

“…The¡fiber properties given in a previous paper [7] are reprinted here as Table IA. The physical properties of these warp and filling yarns, produced from cottons of differing short fiber content, are shown in Table I.…”

Fibre attributes and mapping the cultivar influence of different industrial cellulosic crops (cotton, hemp, flax, and canola) on textile properties

“…Natural fibres (cotton and wool) and many synthetic fibres (aramid) do not have softening or melting point and ignite (combustible temperature) between 415.6 and 537.8 °C (Hatch 1993), although there are many non-combustible fibres such as glass fibres, asbestos, and carbon (Hatch 1993). Tallant et al (1959) defined short fibres as having a length of 3/8 inch (9.53 mm) and shorter that do not break when the yarn ruptures and found that short fibres decrease yarn and fabric strength. Klein (2016) stated that fibre length has an influence on fibre strength as well as on the spinning limit (the point at which fibres can no longer be twisted to produce yarn).…”
