Statement of Purpose
In 2013, after completing B.S. in textile engineering, I joined in the textile printing sector. Basically, unprecedented growth of innovative printing along with its huge market opportunity force me to choose this sector. At first, my focus was career oriented, not even thinking about getting the higher education. But in last four years, I was exposed to many technical problems. I searched on the internet, read books and discussed with my seniors to find out the solution. But ultimately, I realize the necessity of masters degree, in order to enrich my theoretical and technical knowledge on advance textiles. I considered three motivating factors behind my decision, those are, incompatibility between fashion design thinking and its industrial production, identification of the potentiality of sustainable alternative methods over conventional and the last one is the scope for diversified applications and innovations.
Firstly, fashion design thinking is a framework for making products aesthetically attractive by adopting new innovative approaches. But I was intrigued by seeing the disparity between conceptual fashion design thinking of designers and its industrial production viability. Questions like what type of fabric is best for what type of printing process and which process is more cost-effective with less limitation, are still some burning issues in the fashion world. Many times fashion designers demand very critical development like reactive printing on polyester-cotton blend fabric or discharge printing on double part dyed cotton-polyester fabric. But unfortunately, considering current technological aspects in Bangladeshi industrial sector, these are still not attainable efficiently. In this stage, a person with adequate industrial experiences along with advance textile knowledge can minimise the gap between these two sides. Thus being a textile printing technician, I believe that higher education will enhance my knowledge, develop my abilities to identify and to work on potential problems involving fashion thinking idea to its mass industrial production.
Secondly, due to pollution and degradation of natural resources, global textile industries are transiting towards sustainable alternative eco-friendly production process. For example, digital textile printing makes is an ideal choice for its commercial and environmental impacts over the traditional screen printing process. Digital inkjet printing system is energy and water efficient, produces less chemical wastage, eliminates unnecessary steps and requires less time and is more eco-friendly compared to traditional flatbed or rotary screen printing process. Another example would be synthetic leather, which I developed industrially using the blend of rubber, puff and gel chemical. I think that considering the environmental impact of conventional leather production, lab-grown synthetic leather could offer a more eco-friendly alternative. Although extensive research and development needed to know how to incorporate traditional printers more effectively within digital textile printing and synthetic leather production. My aim is to develop the easiest way so that conventional process can be merged within digital textile printing and economic additive manufacturing process for synthetic leather production.
Thirdly, due to widespread support and shifting fashion trends towards smart textiles, there is an exponential room for growth and expansion in terms of innovations and development. I always thought about how mass people can easily get access to products like antimicrobial garments and fully functionalized electronic integrated apparels. Clearly, conventional screen printing technique can be used to produce antibacterial coated printing by using silver nanoparticles or to produce integrated electrical features like wearable electronic sensory textiles, energy harvesting photovoltaic textiles, electroluminescent lamps on fabric by conductive ink and polymers. Moreover, both screen printing and inkjet printing technology could be used to deposit the various functional protective coating on textiles to produce different physical properties like water repellent, UV ray absorbent, flame retardant, moisture absorbent textiles. The new branch of technology, 3D printing-additive manufacturing, not only create an opportunity to reduce pollutants but also could be used to produce completely personalized functional garments. And surely there are innovations that keep evolving not only technically but also hold infinite scope for creativity
Over the years, while working I have seen combinations of multiple printing processes, can create unthinkable functional attractive apparel. For example, I developed several samples by using flock printing within the puff print, crack printing within the flock printing, applying burnout print on cotton-nylon flock coated fabric, pigment printing on burnout printed fabric, different color reflective printing. The most significant one was sublimation photo print on nylon flock coated fabric. The best part was when someone looks at it from a different angle, the print artwork will appear to be of different shades with various color intensity. Moreover, I was involved in two new digital inkjet printing plant setup.
My experiences have taught me to dedicate the time to research the relevant issue thoroughly and analyze critically. For instance, during sublimation printing, I faced problem regarding low resolution printed image on cotton–polyester blend fabric. Although many said this is inevitable due to use of cotton-polyester blend fabric, I searched on the internet exhaustively for a solution. Later I found an article, publication number CA2746913C, which stated to treat the fabric with organosilicon compound before printing. Using hydrophobic sillicone softener was perplexing for me, as always we use hydrophilic softner for pretreating the fabric. But applying the technique I got the desired result. The idea is the sillicone base coat act as an intermediary layer between the fabric and high-resolution printing.
I strongly believe that the program, MS in textiles, apparel and merchandising concentration on textile science, will give me a new outlook as well as a better understanding of different technical methods that will help me to solve the demanding problems faced by the industry today. Besides, I want to work with Dr. Romeo on the research project like emerging 3D printing technology in apparel design and manufacturing. My interest is the feasibility of large-scale production of 3D printing on textiles/apparel surface by fused deposition modeling (FDM) process while using biodegradable thermoplastic compound polylactic acid (PLA). I believe that in near future conventional 3D/ high-density screen printing process will be supplanted by the FDM 3D printer, where we can reduce pollutants, steps, time, and money with a biodegradable product option. I believe that, by working under the guidance of distinguished faculty, I will be able to exploit my potential to the fullest. Considering my experience and enthusiasm for research work, I sincerely request you to consider my application for admission to your esteemed university.
