(Tekstilec, 2018-05) Haque, Abu Naser Md. Ahsanul; Hussain, Manwar; Siddiqa, Fahmida; Haque, Md. Mahbubul; Islam, G M Nazmul
The adsorption kinetics study of curcumin on a cotton fabric was investigated at three different temperatures at neutral pH with 1:20 material liquid ratio and 1 g/L initial dye concentration. Pseudo first-order and pseudo second-order kinetics were approached to experimental data and the adsorption kinetics of curcumin on cotton fitted well with the pseudo second-order kinetic model. The activation energy was 71.96 kJ/ mol, whereas enthalpy and entropy were 68.99 kJ/mol and –59.7 J/mol K, respectively. Dye adsorption declined with increasing temperature, which suggests that the process is exothermic and the negative value of entropy indicates the presence of interaction between the adsorbent and adsorbate.

(Tekstilec, 2020) Islam, Md. Mazharul; Jalil, Mohammad Abdul; Parvez, Md. Shohan; Haque, Md. Mahbubul
Grading is an inseparable part of producing multiple sized patterns in clothing production. From the inception of apparel manufacturing, various methods have been developed for precision pattern grading. Nevertheless, most conventional grading systems have some flaws. The objectives of this study were to analyse traditional grading systems, identify the factors responsible for pattern grading deficiencies and finally, recommend suggestions to minimise grading problems related to the use of CAD software. For the experiments, three different measurement sheets of different buyers were collected and combined into a single specification for better comparison. All garment patterns were then drawn and graded with varying parameters. Later on, measurements of graded patterns were analysed for grading accuracy. This study presents the factors responsible for grading deficiencies and how they can be minimised for higher precision grading for the better fitting of clothing and the prevention of garment sample rejection before bulk production.
Dyeability, Kinetics and Physico-chemical Aspects of Bombyx Mori Muslin Silk Fabric with Bi-functional Reactive Dyes
(Journal of Natural Fibers, 2018-11-17) Farzana, Nawshin; Uddin, Md. Zulhash; Haque, Md. Mahbubul; Haque, Abu Naser Md. Ahsanul
Muslin silk fabric was dyed with three different bi-functional reactive dyes in exhaust method. Dyeability of the silk fabric was analyzed by reflectance spectra, microscopic appearance, color strength, and saturation limit. Thermal influence on dye exhaustion, migration index, level dyeing factor, and color fastness properties were also investigated. Different kinetic models were approached to study dynamic behavior of dye adsorption and predictability of the models was assessed by co-efficient of regression (r2), root mean square error (RMSE), and mean absolute error (MAE). Some physico-chemical parameters such as activation energy and chemical potential of dyeing were also evaluated. Brilliant color was observed on silk by all class of reactive dyes. A controlled dyeing condition was also suggested to avoid the risk of unlevel dyeing. Wet fastness properties exhibited excellent results on silk fabric. The adsorption data conformed to the pseudo second-order kinetic model with r 2 ≥ 0.94 and the activation energy (ΔE) valued (≥55 kJ/mol) within the range of chemisorption for all dyes. The increase of negativity of chemical potential supported higher dye uptake on silk at elevated temperature.
EFFECT OF WEFT PARAMETERS ON WEAVING PERFORMANCE AND FABRIC PROPERTIES
(Daffodil International University, 2009-07-01) Haque, Md. Mahbubul
Threads per inch and yarn count are some of the most important parameters that affect both weaving performance and fabric property. Experimental studies were conducted by weaving fabrics with three different picks per inch (PPI) and weft counts. The study shows that weaving performance is affected by the too high cover factor. Cover factor was calculated by dividing the threads/inch by the square root of the English cotton count and end breakage was taken as an indication of weaving performance. It was observed that when the count as well as threads/inch of one series of yarn changes the crimp% i.e. the consumption of both series of yarns are affected. It was also observed that, as expected, when the threads/inch increases the fabric strength also increases but at higher threads/inch the gain in strength is relatively more.

(Daffodil International University, 2023-07-10) Rizv, Md. Sakhawat Hossain; Haque, Md. Mahbubul; Shahrior, Fahim Ferdous; Majumder, Subrata; Hossain, Md Farhad
For professionals working in the weaving industries worldwide, accurate estimation of warp and weft consumption is a crucial procedure. Both underestimating and overestimating have negative commercial and economic effects. The work presented here is an effort to determine the crimp percentage of denim fabric utilizing a variety of techniques, including marking, set length, and standard crimp tester methods. The investigation was place at a denim weaving facility close to Dhaka, Bangladesh. In this regard, the crimp percentage of denim fabrics with various structures was examined. The set length approach appears to be the most accurate one for calculating crimp%. The study indicates that depending on the fabric construction 10% to 13% crimp is imparted on warp at grey stage, but after finishing it becomes as high as 27% to 30%. This is due to the deliberate length wise shrinkage carried out in the finishing section after weaving. The warp crimp was found to be substantially lower than the warp crimp in denim, as expected, but the completed crimp was significantly greater than the grey crimp. We discovered that warp had a lower crimp% than weft. It's because weaving maintains tension on the warp yarns. Additionally, they are better and stronger yarn than weft. So they stop extending further. Weft yarns, on the other hand, are maintained with low tension and poor quality. in order to stretch farther. Their crimp percentage is higher as a result. Keywords: Crimp percentage, warp crimp, weft crimp, methods to determine crimp, crimp in denim.
Preparation and characterization of handsheet using cellulose based Agri-weed: A sustainable utilization of Urena Lobata fiber
(Scopus, 2024-04-15) Rahman, Sadikur; Hasan, Kamrul; Repon, Md. Reazuddin; Haque, Md. Mahbubul
The increasing depletion of reserves of natural resources has led to a growing worldwide focus on the exploitation of available waste in new domains. The presence of weedy plants is pervasive on a global scale and has detrimental effects on several aspects of the environment, agriculture, and people's health. Therefore, repurposing these Agri-weed plants for beneficial purposes would be a significant achievement. Furthermore, since raw materials constitute a substantial portion of manufacturing costs, using weeds as a feasible substitute for raw materials might potentially provide considerable advantages for manufacturers. In this study, an endeavor has been made to the utilization of agricultural waste “Urena Lobata”, for the purpose of paper production. In the interim, the utilization of Urena Lobata as an alternative and sustainable raw material for pulp and paper industry could potentially offer a beneficial approach to mitigation of deforestation. The effective production of handsheets with weights of 70 g/m2 and 80 g/m2 was achieved using Urena Lobata fiber, Bleached Urena Lobata Fiber, and hardwood kraft pulp. Mechanical characteristics of handsheet's were comprehensively examined by the bursting index, tensile strength, tear index, brightness percentage and scanning electron microscope for handsheet's morphology. The results show that the handsheets produced by Urena Lobata fiber exhibit a much lower brightness percentage, high tensile strength and bursting index. Alongside, handsheets by bleached Urena Lobata fiber indicate higher brightness percentage, satisfactory values for tensile strength, bursting index, and tear index. The prepared materials are suitable for a broad spectrum of prospective applications, encompassing newsprint, tissue paper, filtration paper as well as high-quality writing and printing paper.

Prognosis of Dimensional Stability and Mass per Unit Area of Single Jersey Cotton Knitted Fabric with Fuzzy Inference System [Napoved Dimenzijske Stabilnosti in PloščInske Mase BombažNega Levo-Desnega Pletiva S Sistemom Mehkega Sklepanja]
(Tekstilec, University of Ljubljana, 2019-09-07) Smriti, Shamima Akter; Belal, Shah Alimuzzaman; Haque, Md. Mahbubul; Hossain, Md. Ismail; Farzana, Nawshin; Haque, Abu Naser Md Ahsanul
Endeavour has been made in this research work using experimental data for constructing a fuzzy inference model based on the Mamdani approach to prognosticate the shrinkage and mass per unit area of a single jersey cotton knitted fabric. To control the dimensional stability of the cotton knitted fabric in advance, an artifi cial intelligent system is required in the knitting industry which simulates all product and process variables and is able to give human-like decisions in advance. The most important controlling parameters of knitted fabric properties such as stitch length, yarn count and overfeed percentage in stenter were considered as input variables, and mass per unit area, lengthwise shrinkage and widthwise shrinkage as output variables. Overall, 35 experiments were conducted to construct the model, varying different parameters. The applicability of the model was validated by comparing the results from 15 newly conducted experiments. The coeffi cient of determination of predicted and actual data for mass per unit area, lengthwise shrinkage and widthwise shrinkage were 0.97, 0.99 and 0.99, respectively which validates the model relatively effectively for an industrial application. The proposed model can assist a fabric manufacturer by taking a decision in selecting knitting and fi nishing parameters prior to producing the fabric. Moreover, it can reduce the time and energy required, and waste produced in the process by skipping the sample development step before bulk production.
Study on Material Wastes in Air-jet Weaving Mills
(NC State College of Textiles, 2018) Haque, Md. Mahbubul; Majumder, Subrata
The works reported in this article is an account of wastes generated in two air jet weaving mills producing mills producing 100% cotton fabrics for the export market. Mainly two types of wastes were categorized e.g. (i) wastes related to only warp e.g. gara cones, knotting waste, gaiting/tying-in, loom setting, as beam residue after sizing and weaving, warping, in the sizing zone and the polyester yarns in the auxiliary selvedge etc. and (ii) wastes related only weft e.g. cut fringe, faulty cones, waste due to loom setting etc. The study involved collection of data about various wastes (both warp and weft) of 8 different qualities (construction wise) from the two air jet weaving mills. The amounts of respective wastes were then expressed as percentages of the total quantity of warp and weft. The wastes related to warp and weft were left in the two factories was found to be in the range of 2.59% to 3.96% and 2.43% to 3.51% respectively. It was also observed that the warp wastes in knotting, gaiting/tying-in, loom setting and as beam residue after weaving were insignificant whereas warp wastes in warping and sizing zone were significant. It was also found that finer warp yarns and higher warp thread density were responsible for more waste.Higher waste. Higher set length and greater length of warp in the weaver’s beam generated lesser waste.On the other hand,Inwaste. In case of weft, wastes due to cut fringe and faulty cones were found to be significant, but weft waste due to loom setting was found to be insignificant. The waste due to cut fringe may be reduced if the width of the fabric in increased. The polyester filament (ply) yarns are used as warp in the auxiliary selvedge of fabric seems not very significant. , however due to their high strength; these yarns are being reused again and again for long period of timeIt was found in one of the factory that the cleanersseparate the cut fringes manually leaving only the selvedge warp yarns which are then wound on to any suitable packagefor further use in leno selvedge. Another factory sells their dummy selvedge as scrap at a very low cost.
The Influence of Fabric Weight in the Enzymatic Process (Depilling) of Cotton Knitted Fabric
(BUFT, 2013-12) Mondal, Moni Sankar; Haque, Md. Mahbubul
Enzymes are gaining an increasingly important role as a tool in various wet textile pretreatment and finishing processes (Stanescu, 2002; Thiry, 2001; Cavaco-Paulo, et al. 1998; Heine and Höcker, 1995)[12]. Within 5 to 10 years, wet textile production processing will be shifted from conventional wet textile pretreatment and finishing procedures substantially towards sustainable processes, because of increasing governmental and environmental restrictions and the decreasing availability of fresh water. We analysed the influence of enzymatic treatment process(depilling) using an acid cellulase enzyme on the different weight of cotton knitted fabrics(single jersey) at different time duration and find that depilling effect vary with fabric properties such as density of the fabric which is related with GSM of fabric. The action of enzyme hydrolysis was studied by pilling grade and fabric strength loss percentage.
Valorization of Dyed Brush Fiber Waste Through Production of Upcycled Mélange Yarn
(Elsevier, 2024-04-01) Rashid, Md. Ehsanur; Islam, Md. Atikul; Kanon, Towfik Aziz; Khan, Md. Rubel; Uddin, Md. Bashar; Ul Haque, Raihan; Tonmoy, Md. Washique; Hasan, Md. Rakibul; Haque, Md. Mahbubul
The utilization of recycled fibers from textile waste has greatly increased in recent times due to growing environmental consciousness, legislative sustainability mandates, and escalating raw material expenses. This study seeks to utilize dyed brush fiber waste from a textile finishing machine called sueding, which is also known as emerizing, sanding, or brush machine, in order to create environmentally-friendly mélange yarn. Due to the brush fibers' limited length, the primary obstacle was utilizing them as a raw material for yarn production. In order to surmount this obstacle, brush fibers were blended with raw cotton and subsequently introduced into the carding machine to generate carded slivers. Subsequently, three variants of ring-spun mélange yarn samples were generated, namely: one derived from dyed brush fiber, one obtained from post-consumer waste fiber, and another produced from virgin viscose fiber. In order to verify the existence of the short brush fibers in the yarn, this research conducted optical microscopy on both the sliver and yarn, as well as scanning electron microscopy specifically on the yarn. Next, the quality parameters of ring-spun mélange yarn manufactured from brush fiber are contrasted with those of ring-spun mélange yarn made from viscose fiber and ring-spun mélange yarn generated from post-consumer fiber. The study revealed that ring-spun mélange yarn made from brush fiber exhibited a 6.42% and 4.52% rise in unevenness, an 8.48% and 4.53% increase in hairiness, a 69.02% and 7.80% enhance in imperfection index, and a 16.51% and 13.98% decrease in strength compared to ring-spun mélange yarn made from viscose fiber and post-consumer fiber, respectively. Subsequently, Minitab 2023 was employed to conduct a statistical analysis to determine the significance of various quality criteria. The results revealed that all criteria, with the exception of elongation, were significant. The ring-spun mélange yarn made from brush fiber is of lower quality compared to both grey mélange yarn and post-consumer mélange yarn. This is due to the significantly shorter length of the brush fibers in comparison to viscose and post-consumer waste fiber. Using dyed brush fiber ensures the utilization of waste materials, decreases dyeing expenses, minimizes water and energy consumption, has a lesser environmental impact, and is cost-effective. By incorporating 1 kg of brush fiber into the fiber mixing process, it is possible to decrease water usage by 200–400L, energy consumption by 50–64 MJ, and CO2 emissions by 2.8–6 kg. The utilization of brush fiber in the manufacturing of ring-spun mélange yarn results in a cost reduction of around 10–15 cents per kilogram, in comparison to mélange yarn produced from viscose and post-consumer waste fiber. Additionally, fabrics were manufactured to showcase the visual aspect, demonstrating the versatility of this yarn in creating various clothing such as t-shirts, underwear, and more. The findings of this study suggest that the utilization of brush fiber for the production of mélange yarn may be a feasible option.
