Bangladesh has rapidly become one of the world’s leading garment-producing countries, with the industry contributing significantly to its economy. In the last decade, the garment factory sector has experienced massive growth, making it one of the most important industries in the country.
One of the key factors contributing to the growth of the garment factory sector in Bangladesh is its abundant supply of low-cost labor. Bangladesh has a large, young, and educated workforce, and wages in the country are significantly lower than in other countries in the region, such as China and India. This has made Bangladesh an attractive destination for international clothing brands looking to cut costs and increase profits.
The Bangladesh government has also played a crucial role in supporting the growth of the garment factory sector. The government has implemented various initiatives and policies to encourage investment in the industry, including tax breaks and subsidies, as well as providing infrastructure and support services to help factories operate more efficiently.
Another factor that has contributed to the growth of the garment factory sector in Bangladesh is the country’s favorable geographic location. Bangladesh is located at the crossroads of South and Southeast Asia, making it an ideal location for shipping and transportation. This has enabled clothing brands to efficiently transport their products to markets around the world.
Despite its impressive growth, the garment factory sector in Bangladesh still faces significant challenges. One of the biggest challenges is ensuring worker safety and rights, as many factories in Bangladesh have been criticized for poor working conditions, low wages, and a lack of basic worker rights. The Bangladesh government and international organizations have been working to address these issues, but much work remains to be done to improve the lives of the millions of workers in the industry.
In conclusion, the garment factory sector in Bangladesh has experienced tremendous growth in recent years, and it continues to play a vital role in the country’s economy. However, there are still significant challenges that need to be addressed to ensure that this industry continues to grow in a sustainable and responsible manner.
When most individuals thinks about wearable, they frequently think of the compulsory smartwatches, fitness monitors, and heart rate monitors that are classically worn on the wrist. On the other hand, the wearable market spreads well further than just these typical devices and into numerous developing markets across some diverse businesses.
One such developing market
is smart clothing for healthcare–the idea of interlacing electronics into a
shirt, a blanket, a bandage, a knitted cap, or pants to accomplish particular
patient care tasks such as evaluating and recording the causes and reasons of breath shortness, heartbeat regulation,
and monitoring etc.
Smart clothing, or
e-textiles, as in one piece, is still in its early stages, and applied
applications that are being utilized in hospitals and other care amenities are
rare and far between.
Smart clothing is perceived as a method to transform the run through of healthcare, and it is expected that extensive use of clothes used to monitor health or assist with treatment could decrease dependence on expensive gear and a profoundly weighed down healthcare system. Clothing that can keep an eye on chronic disease or conditions, assist with a rising aging populace, or make patients more contented during a stay at a hospital or treatment facility is grasped as a method to produce value, increase health insights, and lessen prices.
E-textiles are premeditated to feel content on the skin but at the same time be practical. These smart materials comprise of traditional cloth interlaced with conductive fibres as well as electronic essentials such as biomedical sensors, microcontrollers, fibre optics and wearable antennas, such as Mouser’s line of the Internet of Things system-on-modules.
An instance of a biomedical sensor that could be used in e-textile applications is the Analog Devices’ AD8232/33 Heart Rate Monitor Front End. It is an assimilated signal conditioning block for ECG and other bio potential measurement applications, premeditated to excerpt, intensify, and screen minor bio potential indicators in the attendance of loud environments. The Intel® Edison expansion stage is premeditated to reduce the blockades to an entrance for a variety of originators, businesspersons, and customer merchandise creators to quickly archetype and create “Internet of Things” (IoT) and wearable computing produces. It is both a system-on-module answer and an article that integrates a wearable antenna.
The future of healthcare may reside in your smart clothes
In some instances, e-textiles are fashioned, in part, on a characteristic table top sewing appliance that sews yarn into cloth in an arrangement via a computer program. As an alternative to the thread, however, metallic fibres from metals such as silver, nickel, carbon, copper, aluminium, and stainless steel, such as Adafruit’s wearable electronic podiums from Mouser, are used that feel the same as the typical thread to the touch. These products permit you to understand any wearable project. They are completely featured curved, sew-able, and Arduino-compatible devices. They are small enough to fit into any scheme and less costly enough to use without reluctance.
Dependent on how the conductive fibres are intertwined in and the electronics contained within in the smart clothing, the material is hard-wearing and able to be washed alike to a regular outfit. While strength is still a continuing subject in a lot of plans, it is a contemplation that most scientists and businesses are working on as a significant stride in the direction of mass commercialization of smart clothing for healthcare.
The Future of Smart Clothing
While a lot of these educational activities are moving onward and are working in the direction of commercialization, modernizations in high-tech materials and the developments in microelectronics are opening even more prospects for healthcare-related e-textiles.
The future of healthcare may reside in your smart clothes
Some of these designs and early trial schemes consist of t-shirts that get rid of chronic back pain, shirts with stretch sensors for observing respiratory rates with patients with chronic lung disease, lax all-day belly bands that evaluate uterine contractions and foetal heart rate in pregnant females, pressure monitor stocking for use by diabetic patients or even a shirt that conveys shockwaves to patients going through severe heart problems.
Some specialists see smart
clothing totally substituting bedside monitoring in hospitals with shirts that
track heart rate, blood pressure, oxygen intact and more.
In recent times, the indication of assimilating sign recognition in smart clothing has brought in attention with the Google-Levi Project Jacquard commuter jacket for bicycle riders. While a lot of specialists have faith in gesture recognition could find its way into attire for healthcare-maybe for use by paraplegics or elderly those have had strokes or heart attacks or elderly in the home that fall – at this time there are far less costly and recognized machinery that will be difficult to outshine in the subsequent five years.
Haptic feedback, or the
use of touch in an operator interface design, embraces much potential in
e-textiles for the reason that it can be with no trouble reduced and does not
necessitate moving mechanical parts. Haptic feedback would be used in Electric
Muscle Stimulation (EMS) that could sort from a minor sting to robust force
feedback to trigger a patient’s muscles. Smart clothing with haptic feedback
technology could be used at all times for the duration of the day and worn on
any part of the body to encourage muscle movements or rehab. Developments comprising
of haptic feedback, such as those from Novasentis, are at present in
development for use in clothes for healthcare with samples anticipated to
arrive far along this year.
Fabric can be made from interlacement, interlooping , intertwining or bonding of two , one or multiple threads or fibers with specified dimensional stability that can be transformed to apparel or Garments. we are gonna discussing about GSM as wall.
There are three major methods of mechanically manipulating yarn into fabrics
Interlacement or Interwevaing
Interlooping
Intertwining
Interlacement or Interwevaing :-
Two distinct sets of yarns one is called warp yarn and another is called weft yarn are interlaced with each other and produced fabric by loom which is called woven fabric. The lengthwise yarns are called warp and The crosswise yarns are called weft. Weft yarns are also known as filling yarns or threads
Interlooping :-
Interlooping consists of forming yarn (one set yarn such as warp or weft) into loops, each of which is only released after a succeeding loop has been formed and intermeshed with it so that a secure ground loop structure is achieved . knit fabric is produced by Interlooping
Intertwining :-
Intertwining and twisting includes a number of methods such as braiding and knotting where yarns are caused to intertwine with each other at right angles or some other angle
Nonwoven
The planner substance which can be made from bonding fibers with specific dimensional stability that can be transformed to apparel
To produce suitable package from spinners package such as cone, cop, pirn cheese etc. is called Winding
Warping:
To produce warper beam from suitable package such as cone, cop, pirn cheese etc. is called Warping
Sizing:
The process of applying a protective coating upon the yarn surface so that the yarn will suffer the least damage in weaving
Pinning:
The process of passing the warp yarn through the drop wire/ dropper is called pinning.
Drawing:
The process of passing the warp yarn through the heald eye of heald Frame is called Drawing .
Drafting:
The process of passing the warp yarn through the heald eye of heald Frame for a specific fabric such as twill , plain is called Drafting .
Denting:
The process of passing the warp yarn through the dent of reed is called Denting .
Tying-in/ Knotting:
The tail end of the warp from the exhausted warp beam is tied or knotted to the beginning of the new warp is called Tying-in
Soft Winding:
By reducing hardness, the package has to be made suitable for dyeing. It is called soft winding.
Hard Winding:
During winding process a hard package is made from the soft package. Then it is converted to a cone form. It is called hard winding.
Backward Linkage:
The relation of grey fabric with yarn, fiber and polymer is known as backward linkage.
Forward Linkage:
The relation of grey fabric with finished fabric and apparel is known as forward linkage
What is GSM ?
It is the metric measurement of the weight of a fabric. The Elaborate form of GSM is grams per square meter. it is also known as (gm/m2). Some clothing items are still marked in Imperial weights OZ or oz/yd2. OZ or oz/yd2 means ounces per yard squared
We can measure GSM by using following steps without GSM Cutter :
Cut 5 pieces of fabric. (The length and the width of all fabric pieces should be like 12 cm)
Measure the weight of all fabric pieces. (suppose 1.8gm, 2gm, 1.85gm, 1.90gm, 1.95gm)
Then calculate average weight such as
(1.8+2+1.85+1.90+1.95)/5 =1.95 gm
Calculate the fabric sample area
Length * width = 12 * 12 = 144 cm2
Now apply this formula
GSM = (Weight of the samplein Gram*10000)/Area of Sample in cm2
= ( 1.9*10000)/144
= 131.94
Comments :
Fabric weight depends on GSM .
Relation between GSM & OZ :
5.5oz x 33.906 = 186.48gsm
185gsm / 33.906 = 5.45oz
This is very important to understand the variations of fabric weight
