“…This trend could be due to increase the immature fibers, weak fibers and foreign matter content in the low lint grade leads to an increase of neps formation in raw cotton as compared to high lint grade. All trash content increased as the cotton grade decreased (from the high grade (FG) to the low grade (FGF).The same results were in accordance with (Mabrouk et al, 2000 ;Abdel-Malak et al, 2001 and [31][32][33]. Who reported that there were highly significant correlations between lint cotton grade and each one of fiber physical properties and trash content.…”

“…Trash is the non-lint material that contaminates cotton lint. The term can be used for undeveloped seeds, seed coat, fragments, particles of leaf, dust, sand, and stems [10].Trash content has the potential to cause problems with fiber quality measurements [11]. Excessive trash content in the sample may create air channels through the plug of fibers, resulting in an unreliable micronaire reading.…”

hree lint cotton grades; Fully good (FG), Good (G), Fully good faire (FGF) were taken from each of four Egyptian cotton varieties namely Giza95, Giza98, Giza94 and Extra-long Giza96 to investigate the effect of cotton fineness, maturity and trash content on neps formation in raw cotton and yarns. In addition, studying the relationship of trash content, fiber and yarn properties. Results showed that there were highly significant effects of varieties and lint grades on most fiber and yarn properties. Giza96 gave higher fiber and yarn properties such as micronaire value, upper half mean length, uniformity index, short fiber content, fiber strength, lea count strength product, yarn strength and yarn imperfections than Giza94 cotton variety. The lint grade Fully Good gave the best values of all studied traits. Also, it had the lowest trash content, number of neps , unevenness and yarn imperfections than the Fully good fair. The interactions between cotton varieties and lint grades were significant for all studied traits except uniformity index, micronaire, maturity and yarn imperfections (yarn count 40 s and 3.6 twist multiplier ) . Upper half mean length, micronaire value and maturity ratio had negative and highly significant correlation with trash content .While, Short fiber content and trash area recorded positive and highly significant correlations with trash content. Neps / gram and number of neps/400m recorded positive and highly significant correlations with each trash contents, yarn unevenness, thin and thick places.

Effects of non-lint material on heritability estimates of cotton fiber length parameters

et al. 2020

Fiber length is an important parameter to spin cotton fibers. Cotton breeders work to improve length, and research samples may be machine-harvested, resulting in variability for trash content between samples within the same experiment. There is evidence that trash may directly or indirectly affect the measurement of some fiber quality parameters like micronaire and strength. We hypothesize that the presence of trash particles in the samples may compromise the quality of the length measurement and screening decisions in breeding programs. In order to test this hypothesis, we developed an experiment to evaluate the heritability of length parameters for entries with the same genetic background and affected by the same environment with different trash content. The heritability estimates for samples with high trash content are different from the estimates for samples with native low trash content. Cleaning trashy samples with a laboratory-scale lint cleaner brings the heritability estimates closer to the calculated values for samples with native low trash content. Although the values are similar, the types of variation are not the same. These results indicate that breeders must avoid making decisions based on samples with high trash content. Breeders should base their decisions on samples with low original trash content because this type of sample provides research results closer to the native length distribution.
