“…These results were in agreement with the increased presence of impurities due to clamping plates noted by Belot and Vilela (2006) and Willcutt et al (2006). These results also indicated the presence of bark similar to that obtained by Faulkner et al (2011) and Sui et al (2010) with values ranging between 1 and 4% for harvesters using a picker system. Sui et al (2010) state that the separation and the cleaning process of the cotton fibers needs to be more aggressive as increasing the peel can contribute to increasing the amount of short fibers in the samples.…”

An experiment was performed in a cotton-producing property located in Primavera do Leste -MT -(Brazil). the quantitative losses and the presence of bark and stems in the cotton fiber quality measuring instrument as analyzed by High Volume Instrument (HVI) was noted . The study was conducted to investigate a combined speed of work with a mechanical adjustment of the distance of the pressure plates and the screws on the platform. Another objective of this study was to determine reducing quantitative and qualitative losses of cotton fiber. The platform was set at three different velocities (1.02, 1.38 and 1.60 m s -1 ). Two different distances (plate with pressure -3 mm and plate without pressure 6 mm were set as the distance between the spindles and the pressure plates. At these distances, the plants are pressed onto the spindle exerting pressure on the spindles. The collected fiber content of impurities and the efficiency of the machine were analyzed as a function of the total productivity and quantitative losses. Factorial statistical analysis was performed on the data using the Tukey test at 5% probability. A greater presence of impurities and lowest cotton crop losses was observed at the smallest distance between the spindles and the pressure plates.

“…Ring spinning was accomplished on a Suessen Elite ring‐spinning frame, following the protocol outlined by Faulkner et al (2011) but modified to accommodate the longer upland fiber lengths in this study. Specific modifications were (i) the card was operated at 400 rpm for the pima entry rather than 460 rpm for the upland entries; and (ii) the draft of the draw frames was adjusted for each entry, based on their fiber length.…”

Cotton {Gossypium spp.) fibers are produced primarily by G. hirsutum L., upland, and G. barbadense L., pima, or Extra Long Staple (ELS). Two ELS upland lines, developed by Texas AgriLife Research, along with 'FiberMax 832LL' (FM 832) and 'DPL Pima HTO' (Pima HTO), were grown in a randomized complete block design at College Station, TX, during 2007 and 2008. Subplots of spindle-harvested seedcotton were ginned on a saw gin or roller gin with appropriate lint cleaning. High-volume instrument (HVI) and Advanced Fiber Information System (AFIS) fiber parameters were determined. Combed 50-Ne (English yarn count) and 80-Ne yarns were produced. Upland ELS lines exhibited longer (p < 0.01) fibers than FM 832, but only TAM B182-33 ELS produced fibers longer or equal (p < 0.01) to Pima HTO. Upland ELS lines produced stronger 50-Ne ring-spun yarns than FM 832 but not Pima HTO, which also produced stronger 80-Ne ring-spun yarn than the upland ELS lines. While roller ginning resulted in significantly higher micronaire, longer upper half mean length, more uniform fiber lengths, and longer upper-quartile length than saw ginning among these genotypes, yarn parameters reported were not affected. All genotypes responded the same to ginning platform, suggesting that further development of the upland ELS trait will not dictate a change in ginning equipment for upland cotton. The upland ELS trait contributes to significantly improved upland yarn quality.

“…Variation in fiber length exists within a sample, and this variation, along with the ones in other fiber properties, may affect the quality of the finished product (Wakeham 1955;Koo and Moon 1999). Cotton fibers exhibit natural variation in length due to the environment, agronomic practices, and genetic factors (Stewart 1975;Basra 1999;Faulkner et al 2011). The length of a cotton fiber will be at its maximum just before the boll opens.…”

Stability, variation, and application of AFIS fiber length distributions

Background: Fiber length is one of the primary quality parameters for the cotton industry when considering the textile performance and end-use quality of cotton. Currently, many decisions regarding cotton fiber length utilize the industry standard measurement device, i.e., the High Volume Instrument (HVI). However, it is documented that complete fiber length distributions hold more information than the currently reported HVI length parameters, i.e., upper half mean length (UHML) and uniformity index (UI). An alternative measurement device, the Advanced Fiber Information System (AFIS), is able to capture additional information about fiber length distribution. What is currently not known is how much additional information the AFIS length distribution holds. Results: The stability of differences in within-sample variation in fiber length captured by the AFIS length distribution by number characterizing differences between samples was deemed stable across the extended testing period. A diverse breeding population was evaluated and four significant sources of within sample variation in length were identified. A comparison of the ability between HVI length parameters and AFIS fiber length distribution to correctly categorize breeding lines to their family was performed. In all cases, the AFIS fiber length distribution more accurately identified germplasm families. Conclusions: The long-term stability test of the AFIS fiber length distribution by number shows that the measurement is stable and can be used to assess differences across samples. However, more information about within-sample variation in fiber length than that can be captured by length parameters is needed to assess differences across samples in many applications. Four length parameters outperform two length parameters when trying to identify the familial background of the samples in this set. These parameters characterize distributional shape differences that are not captured by the standard AFIS length parameters, UQL and short fiber content by number (SFCn). These findings suggest that additional types of variation in cotton fiber length are not captured and are therefore not currently used in most cotton breeding programs.
