Softness is one of the most important properties for an apparel fabric. This paper investigated the feasibility of objective evaluation of fabric softness by measuring the forces of pulling a fabric specimen through a series of parallel pins. The specific pulling forces of fabric specimens were compared with those indexes obtained both from FAST (Fabric Assurance By Simple Testing) tests and su...

Fabric-based protective clothing is widely used for occupational safety of firefighters/industrial workers. The aim of this paper is to study thermal protective performance provided by fabric systems and to propose an effective model for predicting the thermal protective performance under various thermal exposures. Different fabric systems that are commonly used to manufacture thermal protectiv...

In order to correctly identify the fabric density, a new algorithm based on binary feature matrix is proposed in this paper. A best threshold plane is determined by the gray level of fabric image, the 3D gray image of fabric is segmented according to the best threshold plane and a gray image of feature cluster is obtained. Then the feature cluster is normalized to transform the fabric image int...

While tailoring a garment or a technical textile, relaxation processes of a knitted fabric after production have to be taken into account. Such dimensional changes can occur during a long time of dry relaxation, during wet relaxation, or during washing relaxation, the latter having the strongest infl uence on a fabric. Besides fabric construction and yarn material, the dimensions of a knitted f...

Wind effects on tensile fabric structures (TFS) are not extensively investigated. Available studies consider simplified TFS support conditions and comparisons between static dynamic analyses lacking. The response of a double hypar under varying wind speed is carried out by using fluid-structure interaction (FSI). Realistic considered. geometry determined through form-finding. Computational flui...

We compared diurnal patterns of vaginal temperature in lactating cows under grazing conditions to evaluate genotype effects on body temperature regulation. Genotypes evaluated were Holstein, Jersey, Jersey x Holstein and Swedish Red x Holstein. The comparison of Holstein and Jersey versus Jersey x Holstein provided a test of whether heterosis effects body temperature regulation. Cows were fitte...

In the present paper, a study of the effects of fabric weight, fiber cross-sectional shapes (round, hollow and trilobal) and presence of reinforcing material on the compression properties (initial thickness, percentage compression, percentage thickness loss and percentage compression resilience) of polyester needle punched industrial nonwoven fabrics is presented. It was found that for fabrics ...

A granular material is most likely to possess an initial anisotropic structure due to the depositional process or the previous stress history. There is also induced fabric anisotropy during shearing. Concerning the significant influence of fabric anisotropy on the stress-strain behaviour of a granular material, in-depth investigation on the two kinds of fabric anisotropy is essential. Initial f...

ct such as color or width inconsistencies, slubs, broken ends, etc. The tests on the quality of yarns are usually performed at the output of spinning-mills. Quality test runs for looms and knitting machines require interruption of the weaving process. This interruption is not practically feasible for the machines that are intended for large production runs of fabric rolls. The quality test is c...
