A new approach to improve the performance of spacer fabric for automobiles

The authors investigated the properties of Knitted fabrics produced from polyester-cotton, polyester-viscose, acrylic-cotton and acrylic-viscose spun yarns. Fabric samples were tested for moisture transfer characteristics, capillary rise, sinking time and water absorption. Fibre characteristics at the face and back of the fabrics affect m..

Investigating the strength of three-component self-twist yarns (Russian)

The production of a three-component self-twist yarn is examined and its structure and tensile properties are discussed. Results indicate that the strength of the yarn is considerably higher than that of a traditional self-twist yarn having the same linear density but that the variation in tenacity is approximately twice as low. These resu..

Experimental studies and computer simulations of the draping of woven fabrics

Extensive experimental and theoretical analyses of the draping of woven fabrics have been carried out. The mould set up consists of a hemispherical dome sitting on a flat surface in order to investigate the double-curvature draping. Four types of woven fabrics were tested: a loose plain weave, a tight plain weave, a twill and a satin weav..

Modelling of the permeability of non-crimp-stitched fabrics

It is well established that the flow of resin through the reinforcing fibres during the manufacturing of composites by liquid moulding processes follows Darcy's law. This implies that the fibre reinforcements can be characterised by its permeability through measurements can be characterised by its permeability through measurements or by t..

Online measurement of fabric mechanical properties: Compressional behavior

Compressional behavior of fabrics is important in most enduses. The traditional compression teaster such as KESF (Kawabata Evaluation System for Fabrics) and FAST (Fabric Assurance by Simple Testing) systems are used to perform off-line static measurements. The principle of online measurement of compressional behavior being developed is b..

Evaluating wrinkling appearance and effects of color patterns using image analysis (Japanese)

Using computer image analysis, we evaluate the degree of wrinkling appearance as indicated by the AATCC replica rating system and investigate the effects of color fabric patterns on wrinkling. The angular second moment, contrast, correlation and entropy as textural feature parameters were extracted from the co-occurrence matrix for each g..

Measurement of the principal components of the inplane permeability of woven fabrics

This study covers the evaluation of the principal components of the in-plane permeability of fabric reinforcements from experimental data using a resin transfer moulding (RTM) machine. Various techniques are presented for the mathematical analysis of the flow data, including radial flow in an isotropic porous medium or in an orthotropic p..
