Investigating the effect of different filaments and yarn structures on mechanical and physical properties of dual-core elastane composite yarns

Heliyon, 2023
Dual-core yarns, containing two filaments within the core of the yarn, have gained increasing commercial and research interest recently, especially in denim manufacturing. The use of multi-components in dual-core yarns allows for tailoring the properties

Structure–property of DREF-3 friction spun yarn made using twisted staple fibrous core

Journal of Natural Fibers, 2020
This article discusses the structure–property relationship of DREF-3 friction spun cotton yarn in which the core is a single twisted cotton ring yarn and the sheath is made of the same cotton fibers. The structural changes in the single staple fiber yarn

The effect of false-twist texturing parameters on the structure and crimp properties of polyester yarn [PDF]

Chemical Industry and Chemical Engineering Quarterly, 2017
In this paper, the effect of false-twist texturing parameters (texturing speed, heater temperature, draw ratio and disc-to-yarn speed ratio (D/Y ratio)) on the structure and crimp properties of polyester yarn has been studied using a high temperature ...

Are yarn quality prediction tools useful in the breeding of high yielding and better fibre quality cotton (Gossypium hirsutum L.)?

Journal of Cotton Research, 2023
Background The approach of directly testing yarn quality to define fibre quality breeding objectives and progress the selection is attractive but difficult when considering the need for time and labour.

Functionalization and strengthening of graphitized untwisted carbon nanotube yarn with hot mixed acid treatment

Nihon Kikai Gakkai ronbunshu, 2019
Carbon nanotubes (CNT) have remarkable mechanical properties and low density. Since length of the CNT is limited, CNT yarn is regarded as a reinforced fiber of carbon fiber reinforced plastics.

A computational approach with surface-based cohesive contact for meso-scale interface damage simulation in 3D braided composites

Journal of Industrial Textiles, 2022
The yarn/yarn and yarn/matrix interface debonding has been recognized as a vital failure mode of 3 D braided composites. We present in this paper a meso-scale finite element (FE) model, which considers yarn/yarn and yarn/matrix interface debonding, for ...

Effect of repeated winding on carded ring cotton yarn properties

, 2011
In this study, ten carded ring spun cotton yarns were subjected to windings. Yarn hairiness, fineness, unevenness and tensile properties were then examined. Results showed that the majority of the increased yarn hairiness occurred at the beginning cycles

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...
