To address the future needs of anisotropic conductive film (ACF) applications, a system that enables rapid hardening and prolongs the shelf life of ACFs was developed. In this study, various processing methods and conditions were employed to fabricate microcapsules. Imidazole was used as a hardener for epoxy resin, which was then identified and analyzed using Fourier transform infrared spectroscopy. The latent hardening behavior of microcapsules was examined using differential scanning calorimetry. Thermomechanical analysis and a peeling test were employed to analyze the thermal properties and adhesion. When coated with microcapsules, the hardener reacts to epoxy resin for a longer time. Latent hardeners with differing reaction rates can be prepared by selecting varying shell materials.

In this study, the influence of the wet processing stages, on cotton yarn process ability was investigated. The yarn samples were collected after every treatment and tested for kniteability efficiency. The total evaluation of the yarn properties was measured by using performance diagram. It was found that the highest processability index was occurred after mercerization conditions of 26°Be at temperature 19°C, vat dyeing and at temperature 19°C, reactive dyeing. While maximum processability index with reactive dyeing was occurred with mercerization condition of 28°Be` at temperature 24°C.

In present study, the trials were undertaken on winding machine to study the effect of winding tension process variables on yarn properties. The winding tension was varied at 3 levels and five yarn counts were selected: two medium counts (30s and 36s) and three coarse counts (20’s, 24’s, and 26’s). In all, 15 trials were conducted. The yarn samples were assessed for important yarn properties, such as imperfections, classimat faults, RKm and hairiness, Elongation, IPI, Package density and optimizing tension parameters of individual count for obtaining quality yarn.

The mainstream research discourses and practices have been transforming into interdisciplinary studies recently. The combination of electronics and textiles can be classified as: wearable electronics, textronics and fibertronics, based on degree of integration. This paper discussed about development of cotton wrapped nichrome yarn, copper core conductive yarn, optical core conductive yarn POF of different diameters to produce, nichrome fabric, copper core conductive fabric, optical core conductive fabric and teleintimation fabric. The yarn and the fabrics were tested using a dedicated test rig developed for this research work. This work provides the platform for the methodology of developing conductive yarns and fabric for the wearable electronics product development to progress on the issue of user acceptability.

Today is the golden age of fashion. Fashion garments and apparel has been used everywhere to cope with the fashion era. These fashion garment and apparels are made of the fabrics of various structures and components through various processes. Among them gabardine is one of the most remarkable type of fabric and apparel dyeing is the latest process used for fashion apparel. We are going to have a look into the seam strength variations between dyed and un-dyed gabardine apparels after conceding the garment dyeing process. It is a comparative research work which will deliver us very effective knowledge about various types of seam, seam strength and seam performance. For comparative study many dummy apparels body have been produced as samples which are dyed in Hams washing and dyeing limited. After that all samples have tested in Thermax woven dyeing laboratory. Since Bangladesh is a very potential fashion market and the fashion garments are being manufactured more and more. Hence the fashion trend is rapidly going to garments dyeing from conventional fabric/yarn dyeing processes. Gradually garments dyeing order are increasing higher to higher.

The objective of this paper is to investigate the predictability of some of woven fabric properties using artificial neural network (ANN) and regression models. For achieving this purpose, a neural network with three layers was adopted. The regression model was of type a multiple – linear regression one. The independent variables were weft yarn count, twist multiplier and weft density; and the dependent ones were tensile strength, breaking extension and air permeability of the woven fabrics. The ANN and regression models were assessed using the Root means square error (RMSE) and the coefficient of determination (R2-value). The findings of this study revealed that ANN is superior to regression model in predicting the woven fabric properties.

To improve the natural ventilation of garments is often a crucial task in designing functional garments. Normally, the ventilation can be improved by using appropriate types of fabric, or applying functional design details such vented panels on certain parts of a garment. Apart from these two means, are there any other alternative ways that clothing designers can utilize? Designing is a means to solve problems. Through a patent search, it was found that some inventors have adopted different means of designing to improve natural ventilation. Putting mesh panels on the garments was the most common way to achieve such aim. This design method had been proven by scholarly researches on its contribution on heat and moisture transfer. In addition, some designers noted that the air gap between the garment and body could be a key to affect such natural ventilation. For example, Moretti proposed putting additional spacer objects under the shoulder areas to create a gap so as to improve the natural ventilation of the wearer. Although this new design was claimed to have contribution to enhance natural ventilation for the wearer, the testing results were not provided. In this study, T-shirt designed with larger air gaps on the shoulders was developed. In order to test the effectiveness of this design method on heat and moisture transfer, a series of testing were conducted by using a movable thermal manikin in a chamber with the control of temperature and relative humidity. In order to test the functionality of the chimney/pumping/ventilation effect, the testing was conducted under no wind and windy conditions with a thermal manikin in a standing position, and under a simulated “walking” motion (walking speed of 1.24 km/h). The test results showed that the T-shirt with a larger air gap on the shoulders can significantly improve moisture vapor resistance during windy conditions.

India has a rich heritage of art in the form of embroideries and peoples are well versed with traditional embroidery designs. These may be from Phulkari of Punjab and Haryana; Chamba Rumals or colorful curvilinear Kashmir Kashida. Each region and country has its own distinctive style of embellishment, which incorporates the culture and their history and tradition. Fabric painting can be seen adorning ladies dresses, men shirts, hand bags, curtains, wall hangings, cushion covers and upholstery. The textile material which has been manufactured for a specific end use has lost its utility for that particular end use is term as discarded textile material. Any fabric can be reused even reasonable portion of old and worn out fabrics can be cut-out and used as patches, appliqué or to make household articles. These discarded textiles can be used to create value added products which can be decorative as well as useful. Now-a-days existing designing features used in decorating the prepared articles from discarded textiles is frill, pleats, lace, tucks etc.
