in this work, hydrogel nanocomposites were synthesized by solution polymerization of acrylic acid (aa) and itaconic acid (ia) in the presence of cotton fabric. ammonium persulfate (aps) was used as the polymerization initiator in the presence of a crosslinker, methylene bisacrylamide (mba). insertion of ag followed by reduction of ag+ cations results in a hydrogel nanocomposite. the structure a...
Continuum finite element (FE) models of bones and bone-implant configurations are usually based on clinical CT scans. In virtually all of these models, material properties assigned to the bone elements are chosen as isotropic. It has been shown, however, that cancellous bone can be highly anisotropic and that its elastic behavior is best described as orthotropic. Material models have been propo...
cotton/polyester knitted fabrics as a major production of textile industry was treated with titanium dioxide nanosized particles. the treated fabric with nanosized tio2 became whiter with a good self-cleaning property. also the discoloration of reactive black 5 dye was studied and reported. the stabilization of tio2 on cotton/polyester knitted fabrics by citric acid (ca) with sodium hypophospha...
This paper investigates various approaches for automated inspection of textured materials using Gabor filters. A new supervised defect detection approach is used to detect defect in textile web. Unsupervised web inspection is used with multichannel filtering scheme. This scheme establishes high computational savings and results in high quality of defect detection. The experimental results condu...
Recent shear wave splitting measurements from the fore-arc region of the Ryukyu subduction system show large magnitude (0.3–1.6 s) trenchparallel splitting in both local and teleseismic phases. The similarity of splitting parameters associated with shallow local-S and teleseismic phases suggests that the source of anisotropy is located in the fore-arc mantle. One explanation for this pattern of...
To increase the themosensitive behavior and antibacterial activity of cotton fabric, a series of poly (N-isopropylacrylamide)/chitosan (PNIPAAm/Cs) hydrogels was synthesized by interpenetrating polymer network (IPN) technology using a redox initiator. The IPN PNIPAAm/Cs hydrogel was characterized by Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), and th...
OBJECTIVE To solve the complicated wires and battery maintenance problems in the application of wearable computing for biomedical monitoring, the electromyography (EMG) measurement system using conductive fabric for power supply and electric shield for noise reduction is proposed. MATERIAL AND METHODS The basic cable-free network system using conductive fabric, named as "TextileNet" is develo...
This paper presents EIT-based fabric sensors that aim to provide a pressure mapping using the current carrying and voltage sensing electrodes attached to the boundary of the fabric patch. Pressure-induced shape change over the sensor area makes a change in the conductivity distribution which can be conveyed to the change of boundary current-voltage data. This boundary data is obtained through e...
The tensile strength of durable press finished cotton fabrics is significantly reduced as a result of the crosslinking process. In this research, we investigated the effects of acid degradation and crosslinking of cellulose on the mechanical strength of the cotton fabric crosslinked with polycarboxylic acids, and evaluated various factors influencing the mechanical strength of durable press fin...
The quality of yarn is essential in the control fabrics processes. There some commercial equipment that measures based on sensors, different types, used for collecting data about textile characteristic parameters. irregularity thread influences its physical properties/characteristics and there may be a possibility break during fabric manufacturing process. This can contribute to occurrence unwa...
