“…Some of the collapsed fibers probably turned over, so that we observed the widest ribbon width. Since the never dried fibers have a circular cross section [10] and since the technique for observing fibers in the equatorial optical plane prevented any squeezing of the fibers, this gentle pressure had no influence on the ribbon width of never dried fibers observed in equatorial optical section. The most striking fact is that the 2E of soda swollen fibers in the equatorial optical plane was almost twice the 2E observed in cross sections of the same fibers.…”

“…This phase lasts for 50 d after the beginning of fiber initiation until the boll opens or until environmental factors stop the physiological advancement of the boll (Abidi et al., 2008). Soon after the boll opens, the cotton fibers dry and collapse, forming kidney bean–shaped cross‐sections (Peeters, Wijsmans, De Langhe, De Langhe, & Waterkeyn, 1986).…”

Boll distribution provides an important assessment of the response and adaptation of upland cotton (Gossypium hirsutum L.) to its environment and is strongly linked to yield and fiber quality and consequently to economic value. Several studies have measured boll distribution through end-of-season field or box mapping to study the spatiotemporal characteristics of bolls at both the plant and field levels, to quantify the effects of stress on cotton maturity and fiber quality, and to estimate yield as a function of the relative partitioning of resources to competing sinks. This paper discusses the environmental factors affecting boll production and distribution, reviews methods of measuring and analyzing boll distribution, and discusses the comparative advantages and drawbacks of these methods. With the advent of advanced imaging technologies, this paper also discusses the potential transition from traditional methods to machine-based boll distribution measurements, the challenges associated with these technologies, and how continuous improvements in the baseline technologies being used in the different methods will translate to improved measurement capacities. Overall, major strides can still be made in the area of boll distribution measurement by combining the positive elements in the different studies described in this review to circumvent each of their respective limitations.

“…In general, the width of the ribbon shall be as wide as the diameter if the object has a cylindrical tube structure. Previous studies revealed that cotton bers develop as cylindrical tubes and have a circular cross-section in the boll just before they lose their moisture (27). However, when cotton is dried naturally, the tube structure collapses and forms a at ribbon-like structure of uneven diameter or irregular crosssections with recurring convolutions or twists along the length of the ber (5,(28)(29)(30).…”

Background Cotton fiber fineness is an essential trait for processing fibers into yarn. Fibers that are long, strong, and fine allow the production of high yarn counts, i.e., finer yarns. Existing methods for measuring fineness are time-consuming, tedious, and impractical to evaluate a large number of samples. For this reason, the textile industry has sought a rapid, accurate, and reliable instrument to determine fiber fineness and other fiber quality parameters. Recently, the Optical Fiber Diameter Analyzer (OFDA) was introduced for rapid and precise evaluation of the diameter of different types of fibers, i.e., wool, cotton, and synthetic fibers. In this study, the OFDA was evaluated for measuring the ribbon width of cotton fiber snippets. A set of 104 carded cotton samples covering a wide range of fiber properties were selected and tested with nine replications per sample.Results Before the ribbon width measurement, the repeatability of the OFDA diameter measurement was confirmed. Comparisons with the data (cross-sections, AFIS, and Cottonscope) obtained from previous studies on the 104 samples were used to assess the effectiveness of the proposed method. We observed that the relationship between ribbon widths from the Cottonscope and the OFDA is not very good. Still, there is a strong correlation between OFDA ribbon width and AFIS standard fineness. We hypothesize that the poor relationship between the Cottonscope and the OFDA is related to the medium in which the measurements are performed, i.e., aqueous medium for the Cottonscope and air for the OFDA.Conclusion The OFDA 4000 ribbon width measurement could be useful in a laboratory setting. The results are stable and provide measurements closely related to AFIS standard fineness, a trusted measurement within the cotton industry.
