The current study evaluates the effect of fiber composition in three-thread fleece fabrics if all other knitting and processing conditions remain constant. Four samples of three-thread fleece fabrics were produced on the same fleece machine using the same yarn count and stitch length for face, binding, and fleecy yarns. Some important parameters, namely width, areal density, pilling resistance, bursting strength, and dimensional stability, were characterized. Changes mainly appeared due to the compositional alteration of cotton, viscose, and polyester content in the yarns. The results showed that the fiber composition of the finished samples of three-thread fleece fabrics significantly influenced all parameters studied, except for dimensional stability.

The knitwear industry caters to the needs of the modern youth, whose preferences vary according to the trends and tastes of the modern age. This paper endeavors to demonstrate that active wear fabrics made of eri silk have very good physical properties. The main objective of this research is to investigate dimensional and physical properties of plated interlock, mini-flatback rib, and flatback rib structures developed with two different yarn counts (30s and 40s). The dimensional and physical properties of those samples are investigated in terms of dimensional stability, spirality, bursting strength, elongation percentage, fabric areal density, and fabric thickness. Variables such as yarn count and knit structure play a significant role on the dimensional and physical properties of the fabric.

The Impact

Dimensional measurements were recorded to observe the durability of press-formed paperboard trays used for food processing via heating and cooling of the paperboard trays containing oatmeal. A set of the studied press-formed paperboard trays were dried before being heated, and a set of the paperboard trays were heat-sealed before being cooled to compare the effects of drying and sealing on the durability of the tray. In addition, empty trays were heated to observe the impact of food processing conditions on its durability via leak tests with a colouring solution as well as optical analysis of the material coating on the surface of the trays. The drying process of the trays was observed to improve the dimensional stability of the trays while being heated, and heat-sealing the trays yielded a major positive impact on the dimensional stability of the trays while being cooled. The leak tests and optical analysis results on the heated empty trays showed a negative durability impact from the food processing conditions. It was concluded that adjusting the heat-sealing parameters and food processing conditions is necessary in order to achieve improved durability of the press-formed paperboard trays for food processing purposes.

Warpage and poor dimensional stability of rotomoulded products are two of the main obstacles to the use of this technique in the production of engineering parts. The knowledge of the effect of the processing conditions on the shrinkage of rotomoulded parts will allow overcoming some of the restrictions of this process. In the present work the influence of the processing conditions on the development of shrinkage and warpage of rotomoulded parts was studied. The moulding of the parts was performed using a rotational moulding machine build at the University of Minho. The shrinkage and the warpage of the moulded parts were assessed using 3D MMC (3D measuring Machine Control) equipment, and understanding the microstructural development.

Purpose – Knitted fabrics containing elastane provide high level of comfort and ease of usage because of the elastic and drape properties over the body. Knitted fabrics respond to every movement of the body and return back to its original shape easily so they are used widely for apparel production. The most important properties required from the elastic knitted garments are wear comfort, fit, breathability and durability. The purpose of this paper is to analyse the effect of elastane yarn count and ground yarn count on the performance properties of 12 single jersey knitted fabrics were analysed after dying. Design/methodology/approach – The research design for this study consists an experimental study. In all, 12 fabrics containing half plating and full plating elastane were produced using 30/1-40/1 Ne yarn counts. Bursting strength, stretch recovery, residual extension, air permeability, spirality and drape properties of fabrics were evaluated. Findings – As a result of study it was found a certain effect as the elastane amount and count changed. For all types of knitted fabrics, bursting strength values increased and fabric spirality values decreased as the elastane amount and elastane yarn count increased. Also it was found a significant relationship between elastane amount and count with air permeability, spirality, bursting strength and drape. Originality/value – As a result of the literature review, it was seen that the effects of elastane amount, elastane yarn count and fabric yarn count on the performance properties of knitted fabrics has not been studied broadly.

An awareness of environmental issues is crucial for textile engineering due to increasing consumption of textile fibres. In addition, levels of pollution are ever increasing due to single use polymeric packaging materials in our daily life. Single use polymeric packaging materials, such as PET beverage bottles, have impacts on the consumption of raw materials and energy, on the contamination of our water and atmosphere, on human health, on global climate change. In this point of view, the ability of the textile producers to recycle the disposed PET beverage bottles into textile products has a critical importance. In this study, performance properties of knitted fabrics produced from rPET and cotton/rPET blended vortex and ring yarns are investigated to figure out the reproducibility of environmentally friendly textile products. For this aim, 100% rPET, 50-50% rPET-Co and 50-50% VPET-Co yarns were produced by Vortex and Ring Spinning technologies with same yarn number as Ne 30/1. Then the knitted fabric samples were produced from these sample yarns and the fabrics were dyed. Dimensional stability, bursting strength and pilling resistance properties of the fabrics were examined. Dimensional stability properties of rPET used fabrics were found to be similar with the ones which VPET used. Pilling resistance and bursting strength of the sample fabrics were close to each other that rPET usage does not demonstrate any disadvantage. Consequently, rPET fibre usage instead of VPET fibre is found to be appropriate.

Shrinkage Behavior

Knitted fabrics have a tendency to undergo some dimensional changes and GSM variation due to different knitting parameters. The investigation was carried out to relate the effect of different yarn counts, stitch lengths, machine gauge on fabric thickness variation and shrinkage behavior of the fabric. In this study the experimental results showed that fabric GSM varies as machine gauge changes by using same yarn count. On the contrary, when machine gauge and yarn count was fixed, the changes of fabric GSM was very negligible. For finer yarn count with different machine gauge GSM variation is more compared to coarser yarn count. But with same machine gauge GSM was very closer for both of finer and coarser yarn count. Fabric shrinkage both in lengthwise and widthwise is more fore finer yarn count than coarser yarn count. This study supports that, selection yarn count and calculation of stitch length was not only the way to meet buyer requirements regarding fabric thickness and shrinkage properties. The results found from this work will guide the determination to pick up right machine gauge, management of correct yarn diameter along with meticulous stitch length estimation.

Different Types

The aim of this study was to compare the effectiveness of three different types of resin finishes for improving the dimensional stability of 100% cotton honeycombed pique knitted fabrics. After application of each resin at five different concentrations, it was found that the fabric shrinkage could be effectively controlled by using a suitable type and concentration of the resin. However, the cellulose crosslinking by the resin resulted in some loss in the fabric bursting strength. In a second set of experiments, three different types of softeners were applied, at three different concentrations, in combination with the optimized type and concentration of the resin. It was found that the loss in fabric bursting strength due to cellulose crosslinking by the resin could be minimised with a suitable type and concentration of softener without any deterioration in the fabric pilling properties.
