“…In contrast to our findings, Uyanık (2019) reported no relationship between thin places and yarn quality characteristics. However, the findings of Mathangadeera et al (2020) that yarns obtained from lowelongation samples have thin places, which are a type of yarn defect, are similar to our findings.…”

Cotton fibers are the most important raw material of the textile industry. Clean collection of cotton fibers increases the quality of textile products and the market prices. This study was conducted to investigate the effects of normal and late harvest period of different cotton varieties on cotton fiber and yarn properties. The quality properties of the fibers were determined with the HVI device, and the quality properties of the yarns obtained from the fibers were determined with the USTER TESTER device. The fiber quality properties such as fiber fineness (micronaire), fiber maturity, fiber length (UHML, mm), strength (g/tex), brightness/whiteness (Rd), and yarn quality properties such as yarn evenness (%), thin places, neps+200 (%) and hairiness were investigated in the study. The exposure of fibers to rain during the harvest period of 2018 caused a decrease in the quality properties. Inability of the plants to receive sufficient sunlight during the last physiological development period caused a decrease in photosynthesis rate. This negative situation negatively affected the physical quality properties of fiber and yarn. The results indicated that the physical quality properties of fibers and yarns obtained in 2019 were higher than those in 2018. The aim of this study was to determine the effect of late harvest period on fiber and yarn quality properties and thus on quality of textile products. In addition, the study was carried out to guide researchers who will conduct researchers on similar topics.

“…Our nCounter gene expression suggests that ELO’s expression initiated early at 0 DPA, thus it is very interesting to validate further that how the early expression of ELO influences micronaire trait. Our correlation study established an inverse relationship between fiber elongation and micronaire, which may be crucial for sustain the yarn strength (Mathangadeera et al, 2020) by combining properties of fiber length, density and maturity (Long et al, 2013).…”

Cotton fiber development is still an intriguing question to understand the fiber commitment and development. Here, we remapped >350 publicly available cotton RNA sequencing data on recently published cotton genome with ~400 fold coverage. The differentially expressed genes were clustered in six modules whose functions are specific to commitment, initiation, elongation and Secondary Cell Wall (SCW) fiber development stages. Gene Ontology analysis of commitment and initiation specific modules suggests enrichment of genes involved in organ development. The modules specific for elongation and SCW showed significant enrichment of hydroxyproline-rich proteins and hydrolases. Transcription factors (TFs) binding frequency of defined modules suggested that homeodomain, MYB and NAC expresses at commitment stages but their expression was governed by other TFs. We also mined the stage-specific transcriptional biomarker and Exclusively Expressed Transcripts (EETs) for fiber. These EETs were positively selected during fiber evolution and cotton domestication. The extensive expression profiling of six EETs in 100 cotton genotypes at different fiber developmental stages using nCounter assay and their correlation with eight fiber-related suggests that several EETs are correlated with different fiber quality-related traits. Thus, our study reveals several important genes and pathways that may be important for cotton fiber development and future improvement of cotton.

“…Fiber length is at its maximum prior to harvest; mechanical handling can only reduce the fiber length. Cotton fibers which can maintain their length after aggressive mechanical processing are superior to fibers which suffer from degradation of length and length distribution during processing (Dever et al 1988), spin more efficiently (Fiori et al 1956), and can produce yarns with improved quality and weaving performance (Backe 1996;Mathangadeera et al 2020;May and Taylor 1998). Tougher fibers can better maintain their length during processing.…”

Background The strength of cotton fiber has been extensively studied and significant improvements in fiber strength have been made, but fiber elongation has largely been ignored, despite it contributing to the energy needed to break fibers, which affects fiber handling and processing. High Volume Instruments (HVI) measure fiber elongation but have not been calibrated for this property, making the measurement unavailable for comparative work among instruments. In prior work, a set of elongation calibration materials had been developed based on Stelometer results. A round trial of ten Australian and U.S. instruments was conducted on six cotton samples representing a range of 4.9% to 8.1% elongation. Results By scaling the HVI elongation values of each instrument to the values of the two calibration samples, the coefficient of variation in instrument measurements was reduced from an average of 34% for the uncalibrated measurements to 5% for the calibrated measurements. The reduction in variance allows for the direct comparison of results among instruments. A single-point elongation calibration was also assessed but found to be less effective than the proposed two-point calibration. Conclusion The use of an effective calibration routine on HVI measurement of cotton significantly reduces the coefficient of variation of the elongation measurement within and between instruments. The implementation of the elongation calibration will allow testing and breeding programs to implement high-speed elongation testing which makes the use of elongation values possible in breeding programs.
