“…Finer count yarns better reveal the spinning potential with fewer fibers in the yarn's cross-section. Fibers are fundamental building blocks used to form yarn; yarn strength is related to fiber strength, fiber cohesion, and fiber regularity (Bogdan 1956;Bogdan 1967). Different levels of enzyme and chelator affected the fibers' surface .…”

Flax (Linum usitatissimum L.) fibers can be blended with other short staple fibers, such as cotton (Gossypium barbadense L. or Gossypium hirsutum L.), processed into a yarn, and then manufactured into a fabric. Enzyme-retting is a new, experimental method that decomposes the pectinaceous and matrix substances to separate cellulose fibers from shives using pectinase-rich enzymes and chelators. Spinning tests were used to determine how well fibers were assembled to form yarn and provided an indirect measurement of fiber properties. Miniature spinning allows expanded predictive strategies for ranking fiber production methods such as enzymeretting and resultant yarns beyond traditional fiber testing.

“…Alternatively, certain functions based on scientific considerations of the influence of the particular fiber properties have been derived by some workers to estimate the yarn strength. For example, Bogdan [2] derived an equation for estimating the count strength product of the yarn from the intrinsic strength of fibers, twist factor, etc. Tallant el al.…”

492fiber, strength than those sputi under the high-draft system. 'I'his accounts for the differences observed between the values of a in Table I I. It may also be of interest to note that the values of a and 0 obtained in the present case are in close agreement with those obtained by Louis and I~iori ~-I~. ConclusionThe proportion of fiber strength utilized in the yarn is positively influenced by the tiber length and fineness. The influence of the fiber tenacity varies in the ('TRL and USADL spun samples.The proportion of tiber strength utilized in the CTRL spun yarns of lower counts is lower than the proportion utilized in the USDAL spun yarns of the same count.The difference in the case of yarns of higher count is . negli~ible. This feature has been accounted for by the difference in systems of spinning at the two places.' For lower counts the three-roller system is employed at CTRL, while the double-apron high-draft system is employed at USDAL. For higher counts, however, the high-draft system is followed at both places.Acknowledgments. ABSTRACT Certain functions involving fiber length, fineness, tenacity, and uniformity of length have been developed from scientific considerations for estimating the yarn tenacity of yarns spun under standard processing techniques. The efficiency of these functions in this regard has been compared with that exhibited by the corresponding regression equations involving the fiber properties. It has been found that the efficiency is practically the same in both cases. Hence it is concluded that these simple functions could conveniently be employed for assessing the quality of cotton..

The Co tton Quality Research Station (C QRS) of t he USDA-ARS, recently com pleted a com prehensive study of the relationship of cotton fiber properties to the quality of spun yarn. The fiv e year st udy, began in 20 01, utilized co mmercial v ariety co tton gro wn, harvested and ginned in each of t hree major growing regions in the US (Georgia, Mississippi, and Texas). CQRS m ade extensi ve m easurements of the ra w cotton properties (both physical and chemical) of 154 lots of blended co tton. These lo ts were then spun into yarn in the CQRS labo ratory by vortex spinning with sev eral ch aracteristics of th e yar n and sp inning efficiency m easured for e ach l ot. T his st udy examines the use of a m ultivariate statistical method, partial least squ ares (PLS), t o relate fib er properties to spun yarn q uality fo r vortex spinning. Two different sets of predictors were used to forecast yarn quality response variables: one set b eing only HVI™ variables, and th e secon d set con sisting of both HVI™ and AFIS™ v ariables. The q uality of predictions was no t foun d to sign ificantly ch ange with the addition of AFIS™ variables.
