Day by day its demand increasing swiftly because of western life style and fashion has been accelerated with the trends of casualization across the globe. Nowadays, the present structure of denim (regular, stretch) cannot cover the versatile field of human needs owing to its comfort and stiffness problem. So it is very important to diversification of denim fabrics according to the customers demand and also acquisition the consumer. The main goal of the study is to develop double cloth structure in denim using 30s/1 and 20s/1 cotton (CW) yarn by some selected structures. Moreover, it will create new era by promoting versatility keeping with comfort factors. Here, some denim fabric has been manufactured by using double cloth structure that will give versatility and it affects thermo-physiological comfort. The warmth of a fabric has been found due to the trapping air into the structure and such applications like top garments, baby and kids wear, jacket, coat, cloth for winter season etc. Eventually, the samples have been tested and compared with regular denim on the basis of visual appearance, GSM, tensile strength, shrinkage and stiffness. The developed samples provided satisfactory level compared to regular. Most importantly, findings come due to dissipation the yarn into two layers along with finer count rather than regular denim.展开更多

Different properties like tensile strength, tear strength, dimensional stability to washing, color fastness to washing, color fastness to water, color fastness to perspiration, color fastness to light, color fastness to rubbing, changes in fabric weight were investigated in context with different washing processes for stretch denim fabric. All tests were carried out according to the ISO (International Organization for Standardization). Enzyme washed fabric illustrated better performance regarding tear strength, tensile strength and dimensional stability;but showed moderate performance in different color fastness properties. But the color fastness to rubbing of heavy enzyme stone wash was excellent. No significant change was observed regarding the grade of color change and color staining for color fastness to wash, color fastness to perspiration and color fastness to light with respect to different types of washing processes like enzyme wash, enzyme stone wash, enzyme stone wash with bleaching and heavy enzyme stone wash with bleaching. The grade for dry rubbing and wet rubbing was comparatively better for enzyme wash rather than other washing processes. The GSM (gram per square meter) of stretch denim fabric also increased accordingly after different kinds of washing process rather than untreated stretch denim fabric. The dimensional stability of stretch denim fabric also altered after going through different washing process. The highest shrinkage was occurred in weft direction for heavy enzyme stone wash with bleaching.展开更多

Entrepreneurs from Banglad...One of the most important aspects of Bangladesh’s textile industry is denim. Bangladesh now has a new opportunity thanks to the global demand for denim among fashion industry professionals. Entrepreneurs from Bangladesh provide denim products to well-known international merchants all over the world. The worldwide denim market is predicted to expand by roughly 8% through the year 2020. We must raise the standard of denim if we are to keep up with the expanding industry. In contrast to projectile and rapier systems, air-jet weaving machines nowadays can weave practically all types of yarns without any issues and at higher rates. Due to this, air-jet looms are an excellent substitute for other weft insertion techniques. This kind of device still has one significant flaw, though, and that is the enormous power consumption brought on by the creation of compressed air. Researchers and manufacturers of air-jet looms have therefore worked very hard to find a solution to this issue and achieve a huge reduction in air consumption without compromising loom performance or fabric quality. Therefore, the purpose of this project is to look into ways to decrease air consumption and reduce auxiliary selvedge waste without any decrease in loom performance and fabric quality on existing air-jet weaving looms which reduce the manufacturing costs with process improvement. Just updating the air pressure allowed a weaving mill to reduce air usage by 11 cfm. So, with just almost no cost, a company with 100 looms could save $0.15 M each year, on compressed air. Two new methods for decreasing process costs on air jet looms have also been developed by this project work.展开更多

When we washed a piece of denim fabric, then its properties also changed. The properties are tensile strength, GSM, color fading, stiffness, abrasion resistance, moisture regain, etc. In this study, we conduct different washing processes on denim fabric such are Stonewash, Caustic wash, Acid wash, Normal wash, Pigment wash, Sandblasting, and Super whitewash. After washing, the properties of denim fabric have been analyzed especially strength. The tear and tensile strength were measured by ISO standard. From the above washing method, Normal & pigment wash showed good strength properties comparing with others.

文摘One of the most important aspects of Bangladesh’s textile industry is denim. Bangladesh now has a new opportunity thanks to the global demand for denim among fashion industry professionals. Entrepreneurs from Bangladesh provide denim products to well-known international merchants all over the world. The worldwide denim market is predicted to expand by roughly 8% through the year 2020. We must raise the standard of denim if we are to keep up with the expanding industry. In contrast to projectile and rapier systems, air-jet weaving machines nowadays can weave practically all types of yarns without any issues and at higher rates. Due to this, air-jet looms are an excellent substitute for other weft insertion techniques. This kind of device still has one significant flaw, though, and that is the enormous power consumption brought on by the creation of compressed air. Researchers and manufacturers of air-jet looms have therefore worked very hard to find a solution to this issue and achieve a huge reduction in air consumption without compromising loom performance or fabric quality. Therefore, the purpose of this project is to look into ways to decrease air consumption and reduce auxiliary selvedge waste without any decrease in loom performance and fabric quality on existing air-jet weaving looms which reduce the manufacturing costs with process improvement. Just updating the air pressure allowed a weaving mill to reduce air usage by 11 cfm. So, with just almost no cost, a company with 100 looms could save $0.15 M each year, on compressed air. Two new methods for decreasing process costs on air jet looms have also been developed by this project work.
