Industrial washing is now becoming popular as it increases the value of the fabric properties and appearance. So, the aim of this study is to evaluate the physio-mechanical properties of the sample fabrics after doing enzyme and bleach wash. For this experiment, three different sample fabrics were used: 98/2% cotton/spandex woven fabric, 100% cotto...

Textile coloration is a complex process involving the interaction of dye molecules with fibers in a dye bath. Synthetic dyes pose environmental hazards, leading to increased interest in natural dyes sourced from plants, animals, and minerals. However, natural dyes often require mordants for application to textiles. Despite their eco‐friendliness, n...

Applying flame retardant finish on jute makes flame protective jute products that can be another diversified use of it. The target of this experiment is to observe the flame retardancy improvement of the fabric properties after finishing treatment with various flame retardant chemicals. The untreated (raw) and H2O2 bleached jute fabrics having plai...

This study aimed to investigate the effect of extensibility on cotton blended polyester-spandex core-spun yarn in the weft direction of 3/1 right-handed Z-twill denim. For the preparation of samples, 100% ring spun cotton yarn of 42 tex (14s/1 Ne) was used as warp, and 70:30, 30:70, 60:40, and 40:60 cotton-polyester core-spun yarn of 30 tex (20s/1)...

This study aimed to investigate the effect of extensibility on cotton blended polyester-spandex core-spun yarn in the weft direction of 3/1 right-handed Z-twill denim. For the preparation of samples, 100% ring spun cotton yarn of 42 tex (14 s /1 Ne) was used as warp, and 70:30, 30:70, 60:40, and 40:60 cotton-polyester core-spun yarn of 30 tex (20 s...

Day by day washing process of denim is turning into the art of new fashion trends as it can create various sorts of style and effect in the denim garment. On account of washing, the properties of denim are additionally built up that expands consumer esteem. The target of the present research work is to disclose the modification of the characteristi...

Water is the ultimate and mostly used media during textile materials processing, especially in colouration. This study investigated the possibilities of using seawater for cotton and polyester fabrics dyeing. Single jersey fabrics made of 100 percent cotton and polyester were dyed using a standard recipe and two separate water source as dyeing medi...

The objective of this study was to promote sustainability by offering natural dye extracted from teak sawdust and by replacing conventional mordants or metallic salts with bio-mordants: aloe vera and banana sap. This experimentation further dug deep into analysis of dyeing criteria with respect to controlled variables (the dyeing recipes, time) and...

The recent study helps us to find some important information about deformation of lycra yarn on denim fabric. Though the investigation has been carried out on five types of Twill structure with various range of Lycra percentage(1%, 2% and 3%) but the findings become commercially successful. During first phase without application of solutions, the o...

This work aims to improve the flame retardancy of jute fabric. Raw and bleached plain weave jute fabric was used in this work. Flame retardants borax, diammonium phosphate and thiourea were applied in different concentrations in a raw and bleached jute fabric with the padding method. The influences of flame retardant finishing on the vertical flamm...

Objectives:The objective of the study is to analysis the effect of chemicals on different physical properties and color fastness of treated cotton samples with standard rating values. Methodology: Five single baths are used for the pre-treatment process with five different dosages such as 1g/L, 1.5g/L, 2g/L, 2.5g/L, 3 g/L of NaOH and H2O2. After th...

Objectives: To study the reuse of dye effluents in order to minimize the dyeing cost. Methodology: In this study, the exhausted dye effluents were reused into 7 new dyeing baths along with 7 different percentages of dyes and chemicals to evaluate the color fastness properties as well as shade difference. Firstly, the exhausted dye effluents were co...

The popularity of Sustainable clothing is increasing day by day. Consumers are more interested to consider sustainable clothing design on their daily basis fashion but it is expensive to produce sustainable clothing, as there are less availability of natural fiber. Banana fiber is highly available and it can be a great source of sustainable clothin...

Now-a-days, the importance of natural sources is eminent because the increased awareness created due to most of the adverse effects of synthetic products. In recent years, it has been significantly important to use non-toxic & eco-friendly natural dyes to dye textile materials. Though a lot of research work was done on the application of natural dy...

The demand for environmentally friendly fiber is increasing day by day. Jute is a source of eco- friendly fiber, but years to come, it will be more expensive as the production of jute is decreasing because of the availability of synthetic fiber at low cost. Coir fibers obtained from the husk of the coconut are highly available in the coastal area o...

Natural dyes may be defined as the dyes which are extracted from the flower petals, leaves, barks, steams to ensure environmental friendly dyeing of the sample. Natural dyes are very popular for their different hues and environmental friendly nature but most of the natural dyes are non-substantive and must be applied on textiles with the help of mo...

This paper comparatively evaluated the effect of heat setting temperature on the different physical and mechanical behavior of Lycra single jersey knitted cotton fabrics. The treated samples were subjected to wet processes including scouring, bleaching, dyeing and finishing. In this project the optimum heat setting temperature for the Lycra knitted...

This paper aims to scrutinize the change in physical and chemical properties of cotton knitted fabric with a variety of shade depth (1% to 8%) dyeing with reactive dyes. Shade percentage is an important factor which has various impacts on 100% cotton knitted fabric. The technical factors of GSM, color fastness to rubbing, bursting strength test, co...
