“…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.…”

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.

“…Properties that affect the degree of nep formation include fibre immaturity, fineness (micronaire), low strength, length (in relation to the aspect ratio), high and low wax content and resistance to bending and twisting. Dever et al 58 found nep formation was influenced and inversely related to fibre maturity and directly related to the trash content of cotton. The combination of long-staple length and fibre fineness was conducive to nep formation during mechanical manipulation.…”

“…Yarn strength correlates highly with fibre strength, and good tensile strength specific to fibre fineness, is an important factor in resisting damage through the gin, particularly through the lint cleaner. 58 A minimum tensile strength exists for base grade cotton with large discounts for fibre with values below this level. Table 3.4 lists the descriptive designations given to HVI measured values of tenacity by the USDA AMS.…”

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.
