Different fiber blends, knit patterns, and treatments may be applied to increase the functionality and comfort of knitted fabrics. In this research, the physical properties and bending stiffness of 1 × 1 rib and half-milano rib fabrics with four fiber blends (90% cotton/10% antistatic PET, 80% cotton/20% antistatic PET, 70% cotton/30% antistatic PET, and 65% cotton/35% antistatic PET) applied to each knit pattern were studied. The effect of fabric direction (course and wale), technical side (face side and back side), and treatment (dying, softening with Aquasoft® SI hydrophilic softener, and Polygiene VO-600 antibacterial finish) on the physical characteristics and bending stiffness of the fabrics was evaluated. The results revealed that dyeing and softening increased the fabric area density and both wale and course densities and decreased fabric thicknesses compared to the control fabrics. The antibacterial finish applied to the softened samples did not change the physical properties. Bending stiffness in the course direction was lower than in the wale direction, and it was higher for technical face samples than for technical back ones. The 1 × 1 rib knitted fabrics showed lower stiffness than the half-milano rib fabrics. Treatment of the investigated fabrics decreased bending stiffness for both treatment sample groups compared to the control group.

Natural and man-made fibres of natural origin are more and more widely used, while consideration of sustainability is constantly increasing. The properties and processing behaviour of newly introduced fibres of natural origin are usually compared and often predicted on the basis of widely investigated fibres; however, this prediction sometimes does not have any confirmed basis. Structural parameters and the majority of mechanical and physical properties of knitted fabrics depend on technical characteristics of the knitting machine, on the properties of yarns as well as on the origin of the raw material. This study attempts to develop knits from new natural peat fibres and their combination with widely used woollen, cotton and elastomeric Lycra yarns and to investigate the influence of peat fibre’s nature on structural parameters such as loop length, wale and course spacing, area density, the tightness factor and on main physical properties such as dimensional stability, air permeability and water adsorption.

Cool-touch nylon multi-filament yarns with good heat transfer performance are widely used in the development of knitted fabrics for summer and sports clothing. However, the physical properties of cool-touch nylon fibres, and the effect of fineness and cross-section on comfort-related properties of their knitted fabrics are still not well understood. In this study, the physical properties of cool-touch nylon fibres and common nylon fibres, and comfort properties of knitted fabrics from both fibre types were measured and compared. It was found that cool-touch nylon fibres have better moisture absorption, but slightly lower crystallinity than common nylon fibres. Regarding the fibre fineness and cross-section of cool-touch nylon and common nylon, knitted fabrics showed a similar dependence on thermal comfort properties. Cool-touch nylon fabrics had increased wicking capacity, thermal transfer, and cooling properties, but poorer drying performance and moisture permeability compared to common nylon fabrics. It was concluded that using nylon multi-filament yarns made up of finer filaments and cool touch filaments is an effective way to develop thermal-wet comfort knitted fabrics for summer and sports clothing applications.

Knitting is the mostly used fabric manufacturing processes in Bangladesh through which various types of knitted fabrics with different physical and chemical properties are produced. Single jersey derivatives have some dimensional, physical or chemical properties that change according to some factors and processing. These properties also change after dyeing & finishing process. As finishing is mandatory for fabric production, some tests are carried out after finishing stage & proper controlling is done according desired quality. Single jersey fabrics show low strength and higher abrasion resistance than grey fabric after dyeing & finishing. Finished fabric is more stiff than grey. Spirality & shrinkage properties of the single jersey fabric are rapidly change after dyeing & finishing and generally acceptable under the limit. Therefore, this paper is all about the comparison of physical properties among various grey and finished single jersey weft knitted fabrics which will be helpful to know for efficient production, taking corrective actions to minimize changes of basic physical properties and produce quality knit products.

AbstractThe main aim of this study is to determine the thermo-physiological comfort properties of single knit fabrics and their derivatives. As the Single Jersey knitted fabrics are the most widely used fabrics in the apparel sector, they have been selected for the analysis purpose. Derivatives of single jersey are developed and compared in order to understand the influence of structural variations. Physical properties e.g. thickness and areal density were evaluated for all knitted fabrics with 100% cotton yarn having three different yarn linear densities and after different stages of relaxation. Various thermo-physiological properties have been studied by changing the combed cotton yarn linear density as well as the structure of single knit fabric. Air permeability, thermal insulation and relative water vapor permeability of the fabrics were observed and investigated under wet relaxed states. It is determined that fabric physical properties are affected by changing yarn linear density and by the dry or wet relaxation stages. The percentage/number of tuck stitches (NTS), location of tuck stitches (LTS) and ratio of tuck to knit stitches (RTKS) have strong influence on physical and thermo-physiological properties of single knit fabrics, even though other knitting parameters remained the same.
