The contraction properties of woven fabric are one of the major parameters that significantly depend on
the weave structure of a fabric. It is well established that the contraction of yarns changes with changing
the interlacement sequence or the weave structure. The comparative analysis and justification of warp
contractions for different weave structures are studied in this research work. Eighty type fabrics with
varying weave structure are carefully chosen and the average contraction factors are determined and
compared with each other. The study found a significant variation of contraction among the weave
structures. The plain weave showed the highest contraction factor and satin showed the lowest. But, for a
few intermediate results especially of the derivatives of twill and matt fabrics, the variation of contraction
factor cannot be explained by interlacement sequences only as the final packing of fabric after relaxation
depend on several other factors which are also explained with relevant literatures. Some exception results
are also experienced by very few fabric types. The main goal of this study to determine the impact of variable delivery speed and squeezing roller pressure of the slitting machine on shrinkage of the finished single lacoste fabric, particularly length wise shrinkage. Because it is difficult to control length wise shrinkage and shrinkage has a significant effect on final products. To control shrinkage, different combinations of parameters can be set regarding yarn, stitch length, fabric structure, machine gauge, dyeing, finishing, etc. In this study, focus is given on two such weak zones of a slitting machine where wet fabric gets maximum stretch; firstly from de-twister to slitting knife and secondly the padder (both squeezing and stenter). If it is possible to minimize the stretch in these two points then the length wise shrinkage will be less. To determine the impact, the slitting machine was run in two combinations. In combination 1, the delivery speed was 60 meter/minute with roller pressure 3 bar and in combination 2, delivery speed 80 meter/minute with roller pressure 5 bar was maintained. It was found that combination 1 provides less shrinkage. This convenience continued in drying & compacting machine too, 3 bar and 5 bar pressure was applied and 3 bar pressure was found effective to decrease the fabric shrinkage. In terms of economic significance, jute fiber, a naturally occurring mixture of cellulose, hemicellulose, and
lignin, is second only to cotton. Fibre-reinforced polymer composites have long dominated a diverse array
of applications due to their high specific strength and modulus. In this regard, research has been
conducted on the use of jute and cotton fiber. Not only are natural fibers durable and lightweight, but they
are also inexpensive. This experiment aims to determine the mechanical properties of jute and jute/cotton
blend fabrics. Using ASTM and ISO testing standards, the specimens’ tensile strength, breaking
elongation, tearing strength, stiffness, and pilling resistance were evaluated. The effects of various
variables on breaking force, breaking elongation, and tearing strength were investigated using regression
analysis. It was discovered that the 65/35 jute/cotton blend fabric with 50 EPI, 20 PPI yarn density, and
350 GSM exhibited the best tensile strength, pilling resistance, and stiffness. This research will open up
new avenues for the development of versatile, functional textile products made from jute and cotton. This paper shows a building design especially for the RMG industry of Bangladesh with built in fire safety
system. Due to heavy traffic jam in the road, it takes a long time for fire service and civil defense to reach
in the accidental area. This built in fire safety system can helps to extinguish fire and helps to reduce the
loss of asset due to fire accident until the arrival of fire service in the accidental area. Data is collected
from literature review, case studies and informative interviews from key person of fire service and civil
defense authority for understanding the background of this research. Finally an AutoCAD drawing is
shown for the proposed building design with necessary equipment’s. This design consists a large tank with
automatic watering system for water storage at the roof top of the building. Water is supplied from water
tank to each floor through the water pipe when the chain is dragged by someone such as security guard or
other employee. An emergency chain dragging system is available in the management room which will be
operated in urgent situation such as governmental holidays or at night. An extra motor facility will be
added in this system which ensure watering system in the tank and this power line is taken directly from
governmental line because there will be no electricity connection in the factory when fire accident occurs.
For the sustainability issue, rain water storage facilities were available in this system. Fire extinguisher
ball will be kept in each floor nearest to the various electronic equipment which helps to extinguish fire
when fire accident is caused by E type fire. This building design for RMG industry has not need huge
amount of cost. On the other hand, this system will be added to the existing building without hampering the
productivity. School feeding programs have been a crucial response to food and economic crises and exist in some form
in almost every country throughout the world. According to the empirical evidence, the persistence of
poverty, hunger, and malnutrition is the reason why school feeding programs are implemented in
developing nations. The study has tried to determine whether school meals had generally consistent
positive effects on children’s calorie intake, micronutrient status, school enrollment, and attendance as
compared to non-participants in its many modalities. To comprehend the basis of school feeding and its
development in numerous developing countries, the study applies a descriptive research technique. Data
was gathered from a variety of sources, including journals, research papers, survey reports, and files.
Despite various limitations, significant collaborative attempts are required to attain the intended outcomes
of SFPs in the short and long terms. A need exists, however, for further high-quality studies. Indigo dyes and Sulphur dyes are measured as very fashionable for clothes as they’re having sensible
overall fastness properties. Application of Indigo dyes and Sulphur dyes needs an awfully concentration of
Caustic soda in the time of pretreatment process. The concentration of Caustic soda plays an important
role in denim dyeing. Controlling the concentration of Caustic soda which is used in the pretreatment bath
in denim dyeing, increased the dye uptake on warp yarn, good colorfastness, strength, lustrous and it
ensured to achieve demanded color efficiency (depth of shed) with the use of lower dyestuffs compared to
without controlling the concentration of Caustic soda in the time of pretreatment in denim dyeing. The
optimum value was measured accurately because using data color spectrophotometer for measuring color
strength and other test values were found from laboratory instrument of Nice Denim Mills Ltd. Scouring
and dyeing process is carried out by Padding Mangle. Maximum dye uptake increase was observed at 270
g/l for Indigo Dark Shade, Indigo Light shade, Indigo Medium Shade, Sulfur Dark Shade, Sulfur Light
shade. Also, these findings evidenced that tensile strength could be Decreased in this concentration. The
optimum concentration of strength is 60g/l for light to medium shade and 90 g/l for dark shade. To produce fabric according to the requirements of the buyer is important. As bursting strength is a
dominating factor for determining the property of the knitted fabric, it is a fundamental requirement of the
buyer. In this research an attempt was made to measure the effect of dyeing parameters on bursting
strength of knitted fabric produced from polyester and rayon blended fiber yarn. By changing temperature,
dispersing agent, pH value, amount of salt and soda, different types of salt and soda; the dyeing process
was carried out. After getting the final dyed knitted fabric the bursting strength was measured by following
ISO 2758-2003 test method. Temperature changes showed a significant impact on the bursting strength of
knitted fabric. The variation of pH value, amount of dispersing agent, amount of salt and soda as well as
different types of salt and soda, all had an effect on the bursting strength of the knitted fabric to a smaller
extent. The experimental data showed that the highest strength value was 116.1 kPa for dyeing of polyester
part at 120°C and for rayon part dyeing, it was 108.1 kPa when the temperature was 70°C. Fluctuation of
pH value vary bursting strength merely and the highest value 109.3 kPa was obtained at pH value 7,
addition of 0.9 g/l dispersing agent showed the highest value of 108.1 kPa and for salt and soda amount of
40 g/l and 45 g/l resulting the highest value of 108.3 kPa and 108.1 kPa respectively. In case of using
different types of alkali and salt, Potassium Hydroxide (KOH) and Calcium Sulphate (CaSO4), generated
the highest value which were 110.5 kPa 110.1 kPa respectively. Consequently, the above parameters
should be used for dyeing of polyester-rayon knitted fabric. Industrial Engineering (IE) is one of the important departments in apparel industry. The aim of this study
is to minimize the production time and enhance the efficiency of the work to obtain the actual results
monitored by the IE department. In this study, the ‘IE Solution’ app was developed using a mobile and web
application development platform named ‘Firebase’. This app can be installed on android based mobile
devices. It was designed in such a way that the IE experts can solve their necessary calculations rapidly
and can monitor the production status in the right time. The user application of ‘IE Solution’ consists of
the steps as – signing up to create an individual profile of users; logging-in app that redirects users to the
calculation and hourly production. Here, target, efficiency and Standard Minute Value (SMV) calculation
options. The hourly production form stores the daily production details per hour as well as daily
efficiency. Through this app, the users not only can do the calculation, but also can monitor the time-to-
time hourly production status and show the line efficiency per day. All the information can be stored in this
app and can be accessed conveniently at any time, from anywhere; however, an internet connection is
mandatory. This study investigates the effects of intrinsic and extrinsic motivational factors on employee engagement
in the RMG industry in Bangladesh. Based on Herzberg Two Factor theory this study has followed
quantitative approach to develop the hypotheses. The questionnaire has been adapted from the previous
studies to conduct this study with five Likert measurement scales and self-administered questionnaire has
been used to collect the data cross – sectionally from the total 387 respondents. The data have been
analyzed by SPSS for respondents’ demographic profiles and smart PLS3 for testing the hypothesis. The
findings reveal that extrinsic motivational factors have significant effect on employee engagement more
than intrinsic motivational factors. The coloration of juton yarn, which itself is constructed of 65% jute and 35% cotton, is achieved by using
the abundant and sustainable onion peel extracted dye. The red onion skin is extracted using the Soxhlet
method. Guava leaves (extraction by immersion method) and potash alum (aqueous solution) were used to
fix the natural dyes into the fibers. The coloring was wiped out by three mordanting processes (Pre, Post
and meta mordanting). The dyed samples were tested and evaluated for color fastness (i.e., laundering and
rubbing) and parameters of colorimetry (CIE lab and K/s values) and the determination of the functional
group; transmittance is done through FTIR. The colorfastness properties of alum mordant are better than
guava mordant; for both rubbing and laundering. Yarn dyed using alum mordant shows higher shade
depth as well as color values. The FTIR graph does not represent any significant change in bond
formation on cellulosic fiber. Hence, the eco-friendly common color extracted from the waste onion peel
and potash alum mordant can be an alluring choice for passing on the juton yarn with different exquisite
shades.
