Abstract The aim of this project is to find out the changes that occur in physical properties of denim when it is subjected to enzyme stone and acid wash or to find out the impact of enzyme stone and acid wash. 97% cotton 3% elastomer twill, weave 3/1, construction 72 × 40/9 × 7 indigo dyed denim fabric leg panels as per lab standard recipe are used here to examine. Firstly, desizing was done as pre-treatments and after treatment was silicon softener. After washing process, different samples from both washing are going to express different behavior on physical properties. This experiment is done to find out the discrimination in tearing strength, shrinkage %, color fastness to wash, color fastness to rubbing, pH rate between stone enzyme wash and acid wash of denim garments.

Abstract The mechanical performance of knitted fabric was significantly affected by loop density and geometries. Knitted fabric composites occupy a special position in the field of engineering materials because of their easy to form com plex components and high impact energy absorption. But Knitted fabric composites have low in-plane tensile strength because the yarns are in a loop structure in the materials. Sound insulation requirements in automobiles, manufacturing environments, and equipment, generating higher sound pressure drive the need to develop more efficient and economical ways of producing sound absorption materials. The knitted fabric based acoustic materials were produced from cut wastes from different garment industries for their sound absorption property test as per the method described in ASTM E 1050. The acoustic performance of knitted fabrics was measured by independent tube methods for sound waves of 1000-6000 Hz. It is observed that the knitted fabrics acoustic materials prepared from waste materials showed high sound absorption than woven fabrics made from the same synthetic fibers. Moreover, the test revealed that blended knitted fabric had a better sound absorption property.

Abstract Pressure applied on the top roller of drafting zone is a vital factor on which the quality of ultimate yarn depends. Drafting zone is needed to reduce the mass per unit length of input material. Appropriate contact of top rollers with bottom rollers is necessary to ensure proper drafting. In this paper, the effects of different front top roller pressure of drafting zone on the quality of 20Ne cotton-flax blended yarns (C:L = 45:55) were studied. It was observed that a higher pressure value gives a lower co-efficient of mass variation, imperfections, hairiness and higher evenness, tenacity, elongation propert .

Abstract This paper deals with garments wastage, which could proficiently assess alternative sizing materials than conventional sizing materials. In this research, the synthesized Carboxymethyl Cellulose (CMC) was originated from garments wastages and after that, synthesized CMC and exported CMC were added in sizing recipe for newly sized yarn and conventionally sized yarn respectively. Yarn count, strength, CSP, de sizing efficiency and dye absorbency have been evaluated and a comparison has been made among the samples. Less count variation was found in newly sized yarn and a desirable amount of strength & CSP were also acquired in newly sized yarn but it was slightly less than the conventional one. After de sizing and dye absorbency test, it has shown a favorable character for further steps like dyeing, printing, etc. These findings convey that synthesized CMC prepared from garments wastage in this study are good candidates for alternative sizing agents.

Abstract Textile chemicals such as dyes, printing pigments, additives, oxidizing agents and reducing agents can be very injurious to the body and the environment if not properly used. The prime focus of this study is to promote and maintain a safe and healthy environment by ensuring the highest level of environmental health and safety assistance for small scale textile dyers and chemical suppliers within the Sekondi-Takoradi Metropolitan Area of Ghana. Case Study, a descriptive research approach is used because data came mainly from arc hives, library and by direct observation of textile production practices at the small-scale level. The population for the study involved batik producers, tie dye producers, screen printers and textile chemical suppliers and dealers. Interviews and observations were used in soliciting relevant data. Data collected was analyzed and presented. The study suggests appropriate ways of working with dyes and other chemicals for dyeing. It also simplified information on the available Material Safety Data Sheets (MSDS) for the understanding of the textile producers. This was tailored towards improving communication with the small-scale textile producers who collectively constitute a big percentage of textile producers in Ghana.
