-The area of the digital image processing is getting more attention in the hope that it will increase the accuracy of any scientific measurements. One of many digital image processing applications is texture analysis. Fabric or cloth is a flexible artificial material that is made by a network of natural or artificial fibers. Fabric fault inspection is an important process in the textile industr...

This research project combines computer-aided-engineering methods with practical control strategies to develop precise fabric handling capabilities. The primary goal is to develop mechatronic design concepts for assembly processes such as: folding, joining, placing, and locating that take into account variability in fabric material properties such as weight and stiffness. Advanced three-dimensi...

Fabric quality and durability are a concern with fibers that contain natural antibacterial properties or are treated to provide antibacterial properties. The textile industry has developed antibacterial fabric to address the public’s desire for improved sanitation and personal protection against disease transmission. The approach has been to attach biocidal or some bacteriostatic groups to the ...

Current shielding effectiveness (SE) of electromagnetic shielding (EMS) fabric is tested in the plane state, the testing results are difficult to describe the shielding effect of a garment in a curve surface state after manufactured by the fabric. To solve this problem, this study proposes a new SE computation model of the EMS fabric based on a SE vector. The model can calculate a theoretical S...

Here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (TEA) and zinc acetate. The ZnO nano particles (NPs) were formed and stabilized on the fabric surface by amine compound at 130 °C for 1 h. The synthesis of nano ZnO particles on the polyester fabric were confirmed by X-ray diffraction (XRD) pattern...

Response of a fabric to applied forces normal to its plane is known as fabric compressional behavior. It is one of the important properties that determine fabric performance in many applications. The principle of a system used to measure fabric compressional characteristics, online, is proposed in this paper. A controllable nip formed by a pair of rollers is employed to apply compressional defo...

Broken ends, missing picks, oil stain and holes are the most common fabric defects. To deal with the situation that manual fabric detection will affected by the subjective factors of inspectors, an automatic computer vision based fabric defect detection method is introduced in this paper. The system uses threshold segmentation method to identify if there are any defects existed in the fabric, a...

The goal of our research works is to build a software for fabric modeling. Our research team wants to simulate any fabric deformations due to mechanic stresses. This paper deals with our solutions to speed up calculus convergence of fabric model simulation. These solutions are based on clever propagation algorithm, multi sampling and displacement prediction. Into bibliography, there is several ...

Conventional loose-weave cotton operating garments were compared with clothing of a non-woven fabric to test their efficacy in reducing the dispersal of skin bacteria into theatre air. When men wore operating suits made of the non-woven fabric dispersal of skin bacteria was reduced by 72%. When all the operating-theatre staff wore suits and dresses of this fabric air bacterial counts during ope...
