Interpretive Summary: The relationship between cotton fiber and yarn properties is of great interest, because this knowledge is of extreme interest to cotton breeders for cotton enhancement and to fiber processors for improved yarn processing. Over the years, significant researches have been taken to unravel yarn processing and product qualities by relating them with fiber qualities in raw cottons that were measured predominately by high volume Instrumentation (HVITM) and advanced fiber information system (AFIS). This study examined the relationship between cotton fiber micronaire / fineness and yarn linear density, also between yarn breaking force / tenacity and yarn linear density, since gravimetric yarn linear density can be easily calculated for a weighted skein yarn if the yarn length is known. From a small sample set, fiber micronaire / fineness property and yarn count / tenacity increase with yarn linear density. The preliminary outcome provides cotton fiber / textile engineers and researchers a new sight in a fundamental understanding the relationship between fiber and yarn property

Technical Abstract: A fundamental understanding of the relationship between cotton fiber and yarn properties is important, as fiber properties are determined through a number of well-defined protocols. In this study, yarn linear density was assessed by a gravimetric method, and then was compared with fiber HVITM micronaire and AFIS fineness as well as yarn count and yarn tenacity. In general, fiber micronaire / fineness property and yarn count / tenacity increase with yarn linear density. Interestingly, linking yarn tenacity to linear density indicates different patterns among individual varieties.
