Influence of stitch length and structure on selected mechanical properties of single jersey knitted fabrics with varying cotton percentage in the yarn
Knitting is a process of manufacturing a fabric by the intermeshing of loops of yarn. Knitted fabric possesses high stretch and recovery, providing greater freedom of movement and outstanding comfort qualities for which they have been preferred as fabrics in many kinds of clothing for a long time. In clothing design and manufacturing, fabric characteristics are usually dictated by a specified end-use.1,2
Characteristics of fabrics knitted with basic knitting structures from combed ring and compact yarns
The abrasion resistance, pilling tendency, Lab values, K/S value and burst strength of fabrics with basic knitting structures of RL-jersey, RR-ribbed, RR-interlock forms produced from 100% combed cotton ring and compact yarns have been studied and compared. It is observed that the differences between the structures of ring and compact yarns play a significant role on the fabric properties. The fabrics produced from compact yarns are found to have better abrasion resistance, higher burst strength, less pilling tendency, better dye absorption, and dyeability in more vivid colors.
Some fundamental aspects of glow discharges in plasma-assisted processes☆
Abstract The applicability of some theoretical models for ionization-assisted processes, such as those of Davis and Vanderslice and Child-Langmuir, are discussed using data obtained by the authors and other researchers in the field. Information derived from argon discharges is used as a basis, and provides a convenient foundation from which to compare different system layouts, such as the direct current diode, and various triode systems. Detailed information is given on the estimation of the cathode fall distance L and the L /λ ratio, where λ is the mean free path for charge exchange collision. This allows the estimation of energy distributions for both ions and neutrals. Other important parameters are also discussed, such as ionization efficiency, as well as the effect of additional species within the discharge.
