“…Similar to other studies the number of lint cleaning passes had significant effects on nep levels (Anthony et al, 1988; Dever and Gannaway, 1988; Hebert et al, 1986; Mangialardi, 1985) (Table 4). One lint cleaning pass contributed an extra 97 and 95 neps for Exp.…”

“…As a result, the mean contribution of lint cleaning to neps were 144 more neps for 1 lint cleaning pass and another 181 more neps for a second pass. Anthony et al (1988) and Mangialardi (1985) also showed that the increase in neps for each lint cleaning pass was essentially equal in magnitude except when lint had been excessively weathered.…”

“…More neps (in cotton with no lint cleaning) and immature cotton was associated with earlier harvest aid treatments across all experiments (Table 4). The number of neps was negatively correlated with linear density ( r = −0.83), maturity ratio ( r = −0.63), and micronaire ( r = −0.74) indicating that production of immature or low linear density fiber was most likely the reason for increased neps (Anthony et al, 1988; Dever and Gannaway, 1988; Hebert et al, 1988; Mangialardi et al, 1987). Upland cotton fiber with maturity ratios < 0.85 or a micronaire‐value <3.5 are generally considered immature.…”

“…I mmature bolls will usually contain immature cotton fibers, which are prone to entanglement and the formation of neps (Anthony et al, 1988; Gordon, 2007). Neps are small entanglements of cotton fibers that are created during mechanical processing and often contain dead or immature fibers (Hebert et al, 1988).…”

Immature cotton (Gossypium hirsutum L.) fi bers and neps in ginned cotton will aff ect textile quality and thus can aff ect overall industry reputations. Th is study conducted three fi eld studies that systematically varied the timing of harvest aid application to generate diff erences in the amount of immature fi ber and levels of neps in crops at harvest. Th e aim was to ascertain what crop conditions (percent open bolls, number of immature bolls, percent immature bolls, and percent immature lint mass) at the time of application contribute to these diff erences, and assess whether these outcomes are infl uenced by 0, 1, 2 lint cleaning passes. Earlier harvest aid treatments increased neps and the level of neps was best related to fi ber linear density (r 2 = 0.78). All measurements of crop condition at harvest aid application explained changes in yield and fi ber properties well, although the percent immature bolls (r 2 > 0.67) can be applied when crops are nonuniform in their maturity, and when they contain fruiting gaps. Relationships between lint cleaning passes and crop condition at harvest aid application showed an interaction between earlier harvest treatments and lint cleaning passes. One lint cleaning pass contributed between 95 and 141 count g −1 more neps, while a second pass added between 101 and 181 count g −1 more neps. Th is information will be valuable in refi ning strategies that aim to optimize both yield and fi ber quality (including less neps). Th is study also supported the current recommendation of applying harvest aids at 60% open bolls.

“…In contrast to mature fibers, immature (or low maturity) fibers contain less cellulose and more noncellulosic components. The presence of a large amount of immature fibers in commercial cottons has been found to cause entanglement during mechanical processing and also to affect the desired color appearance in dyed yarn and finished fabric products [ 3 , 4 ].…”

Cotton fibers are natural plant products, and their end-use qualities depend on their stages of development. In general, the quantity of cellulose in cotton fibers increases rapidly, thus it leads to compositional, structural and physical attribute variations among the fibers with shorter and longer growth periods. This article discusses recent progress in applying the Fourier transform infrared (FTIR) spectroscopic technique to characterize these differences, to discriminate immature fibers from mature fibers, to assess fiber maturity and crystallinity and also to unravel the band assignments in crystalline and amorphous celluloses. The results were achieved through the use of various strategies, including wet chemical analysis, principal component analysis (PCA), simple algorithm development, two-dimensional correlation analysis and other independent fiber tests. Of particular interest is that, in general, immature fibers might have the characteristics of less than 21–28 dpa, MIR < 0.58 (in the maturity range of 0 to 1.0) and CIIR < 42% (in the crystallinity range of 0 to 100%).
