“…Also, it was shown that lines contributed higher for neppiness in this population because of significant differences among lines for SCN count, SCN size and nep size while non-significance for testers (Table 1). Genotypic differences for neppiness were determined by Mangialardi and Lalor (1990), Boykin (2008), Zeng and Meredith (2010) in cultivated species of cotton (G. hirsutum L. and G. barbadense L.).…”

“…The mean square of parents vs hybrids for only nep size indicated that difference between the mean of parents (683.1 µm) and hybrids (651.7 µm) was significant (Table 1 and Table 2). In respect of neppiness, reduction in count and size of nep and SCN can improve yarn performance and fabric color quality (Mangialardi and Lalor, 1990). Among parents, testers, Flash, Carisma and ST-468 cultivars, were noteworthy as the parents with the worst fiber characteristics ( Table 2).…”

“…The genotypic differences and heritability on AFIS data for neps and seed coat neps have been few studies. Significant differences for neps and seed coat neps were identified among cotton cultivars in both G. hirsutum L. and G. hirsutum L. x G. barbadense L. hybrid populations (Mangialardi and Lalor, 1990;Boykin, 2008;Zeng and Meredith, 2010). The information on gene action and combining ability of neps and seed coat neps are needed to identify the suitable parents and promising cross combination in breeding program.…”

Information about heritability and combining ability for neps and seed coat neps is necessary for the cotton breeding strategies. Seven cotton cultivars including 4 lines and 3 testers were mated in line x tester mating design. The 19 genotypes were grown in RCBD with three replications in Aydın-Turkey conditions during 2014 growing season. Non-additive gene action was important in the expression of seed coat nep size, nep count and nep size. The parental lines Carmen and Claudia were good combiners for most neppiness characteristics. Carmen x Flash, Julia x ST-468, Claudia x Carisma and Gloria x Flash were the superior crosses for selection in further generations of neppiness breeding. It was recommended that the selection of individual plants for neppiness should be performed in later generations (F4-F6).

“…Middle planting dates were 24 March and 22 March in 1997 and 1999, respectively. Late plantings were 11 April and 12 April in 1997 and 1999, respectively. Bolls from a 1-m section of a middle row were harvested from each plot.…”

I A number of preharvest and postharvest factors alter textile quality, including cotton variety, growth environment, harvest method, lint cleaning, and combing. In this work, the impact of three planting dates in 1997 and 1999 on fiber properties, mote, neps, and white specks is monitored. Cotton is hand picked, ginned on a small laboratory gin, and processed in a mini-spinning facility. The number of motes per gram of seed cotton does not correspond to changes in nep or white speck frequency. Also, a decrease in the mean micronafis values (which corresponds to micronaire) does not correlate with increases in white speck frequency.The range of 0 values is larger for 1999 cotton than for 1997 cotton. We propose th the distribution of 0 values is important in predicting white speck potential, and that the amount of very mature fibers may be just as important as the amount of immature fibers.

“…However, the tendency of fibers to entangle into neps during the ginning operation was reported to be more correlated with the flexural rigidity of fibers-as determined by their length and fineness-and the amount of foreign matter content. Mangialardi et al reported that both variety and the degree of mechanical lint cleaning significantly impacted the final nep count [27]. Their results showed that the varieties with lower nep counts were also associated with higher micronaire values.…”

This review discusses the important concept of cotton fiber friction at both the macro-and nanoscale. First, the technological importance of fiber friction and its role in fiber breakage during fiber processing is discussed. Next, previous studies on frictional properties of cotton fibers are reviewed and different experimental procedures to measure friction between fibers or against another surface are evaluated. Friction models developed to explain friction process during various experimental procedures are considered and their limitations are discussed. Since interpretation of friction processes at the macroscale can be challenging (mainly due to difficulties in analyzing the multiple asperities in contact), a separate section is devoted to surveying studies on the emerging field of single-asperity friction experiments with atomic force microscope (AFM). Special attention is given to studies on nanoscale frictional characteristics of rough viscoelastic surfaces (e.g., plant cuticular biopolymers and cotton fibers). Due to the close relationship between friction and adhesion hysteresis at the nanoscale, adhesion studies with AFM on viscoelastic surfaces are also reviewed. Lastly, recommendations are made for future research in the field of frictional properties of cotton fibers.
