SAXION RESEARCH GROUP SMART FUNCTIONAL MATERIALS

SAXION RESEARCH GROUP SMART FUNCTIONAL MATERIALS

Internship and graduation assignments at Saxion Research Group Smart Functional Materials, starting September 2017. Would you like to work full-time on your research during your internship or graduation assignment and have a team of experienced researchers available for questions and support? Participate in one of our projects with innovative, sustainable and functional textile solutions in the research group Smart Functional Materials. With 3 research lines, an international network and a large portfolio of research projects, we are constantly looking for students. This document contains the student assignments (either intern or graduation) starting September 2017. Please contact us if you have any questions or suggestions. You can meet us at the 2 nd floor (room G2.27) of the Epy Drost Building (Van Galenstraat 19, 7511 JL Enschede) or send an e-mail (Laura Erkens: l.m.erkens@saxion.nl).

3 RESEARCH DOMAINS 1. Sustainable Textiles Within this research line, led by Gerrit Bouwhuis, we focus on new materials made of cotton waste (like the SaXcell fibre), applying biopolymers in technical textiles and development for recycling. 2. Responsive Smart Textiles Led by Eliza Bottenberg, this research focus on the development of smart textiles that can react with changes in the surrounding. For example a sensor carpet that measures where a person is walking or a sensor shirt that measures respirations and heartbeat. 3. Surface Modification Within the research line surface modification, led by Henk Gooijer, we focus on adding or improving functionalities of textile materials. For example digital printing or 3D printing. One example is printing special nanoparticles with antibacterial properties for hospital textiles.

Sustainable Textiles SaXcell Recently, we have achieved the recycling of cellulose waste into a new innovative cellulose fibre: SaXcell. The SaXcell fibre can be spun and woven or knitted into a new fabric. Research of students is very important within this project to optimize the fibre. Two graduation assignment are available within this project. More info about SaXcell can be found here: www.saxcell.nl s Market introduction strategies for SaXcell fibres The SaXcell fibre is suitable to be converted into a 100% SaXcell yarn. However, this material is different to existing materials at the textile market. For this reason, intimate mixed fibres of SaXcell yarn with different amounts of i.e. cotton or polyester could be prepared, that have similar characteristics as known materials at the market. The student should look at strategies to introduce SaXcell into the textile market and should focus on the difference between 100% SaXcell and SaXcell inside. Characterization of waste streams for the SaXcell process The recycling process of SaXcell fibre strongly depends on the concrete waste stream. Pure cotton waste is rare and will increase in prize as the demand on this pure waste increases. Other textile waste streams often have impurities like other textile materials and dyestuffs that make the recycling process more complex. The student will look at the different waste streams that are available as cellulose source for the SaXcell process and will analyse the waste streams on cellulose content, impurities, costs etc. For more info you can contact Mr. Jens Oelerich.

GOING ECO GOING DUTCH GEGD Textiles and sustainability is an important theme in the Dutch textile, clothing and fashion world. Saxion, Texperium, ArtEZ and several Dutch textile and fashion companies cooperate in the project Going Eco Going Dutch. The goal is to show that, based on sustainable fibres and fibres produced in the Netherlands (hemp and recycled textiles), beautiful new products can be made. Several students are needed for the project. These students will focus their research on: textile recycling, spinning of recycled fibres, design for recycling (D4R) or recycling in design (RiD). If you are interested, please contact Mrs Theresa Grevinga for more info: t.h.grevinga@saxion.nl.

RESPONSIVE SMART TEXTILES Texenergie The project Texenergie is about the integration of flexible solar cells and batteries in textile materials. This is a way to produce innovative and sustainable products that (as standalone) can harvest and safe energy. In cooperation with international companies, research centre and research groups from Avans and Saxion, several prototypes will be developed. State of the art technologies for solar cells and batteries will be used to develop the prototypes. For the research and development of several prototypes, we are looking for textile, chemistry, physics, electrical engineering and industrial product design students. Depending on your background and interests, a specific assignment will be finalized. For participating partners, we will develop prototypes like: sport-shirts, curtains, military equipment, tensile structures, work wear and a composite guardrail. s could focus for example on design of the products, laminating of stitching of the flexible solar cells, flexible batteries in in seams, etc. More info about the project can be found at: www.texenergie.nl Eliza Bottenberg, Carlos Kuhlmann or Laura Erkens will coach the students. Sign Up If you are interested, please contact Mrs Eliza Bottenberg (e.bottenberg@saxion.nl). Send your application; enclose a short CV and a short motivation. We will arrange as soon as possible an intake, where we can further explain the project and discuss the assignment.

RESPONSIVE SMART TEXTILES Shape memory technology The field of shape memory technology is booming. More and more materials appear that are able to change shape as a result of various external influences. Examples of these materials are Shape Memory Alloys (temperature/stress), magneto-restrictive materials (magnetic field) or photomechanical materials (light). As a research group in applied research, we think these developments are almost available to be used by companies within our field, technical textile companies. For this assignment, you will perform a research about the status in research, state of the art and commercially availability of these materials. If possible, you will choose one materials and work on a proof of principle products within the technical textiles field. More information about shape memory technology can be found for example in the Status and trends in Shape Memory Technology report (Stoekel, 1992), or the research paper Shape Memory and Super Elasticity (Sehtoglu, 2015). Reprinted November 27, 2015, from thermally activated 3d textile with shape memory, http://designsociety.dk/2013/05/09/thermallyactivated-3d-textile-with-shape-memory/ Mrs Eliza Bottenberg will coach the student.

COOLING GARMENT Cooling Garment For professional applications we started the development of a completely new cooling garment: a garment for fire fighters that ensures the body temperature stays doable with physical activity and high temperatures. The project is running in cooperation with large partners from the industry and aims at a high quality end product. Within the project quality research of new developed textile materials is important. The student will perform several experiments on the fabric touch tester. Also washing tests, sweat tests, etc. are part of the assignment. For more info, you can contact Mrs. Marijke Timmermans E-mail: m.i.timmermans@saxion.nl

3D printing of textile like structures 3D printing The over-production of textiles is a serious item. We are researching possible future production methods and technologies to minimize issues like this one. Customization is a possible approach to counteract over-production. 3D printing would be an excellent technology for customization of product and possibly clothing. In which degree can textile characteristics and therefore clothing be mimicked by 3D printing? In the past years we worked hard on the 3D printing of a garment with a knit-structure, a movie about this dress can be viewed here: https://www.youtube.com/watch?v=xih6q95pcrm&feature=share. This garment however is not printed with the accessible widely used desktop 3D printers. We would like to continue this research by researching in what degree textile can be mimicked by using those desktop 3D printers. Therefore, we need you! Will you make the next 3D garment?

Model for 'Comfort' functionality of Outdoor fabrics Model for 'Comfort' functionality of Outdoor fabrics The project is in collaboration with Ten Cate Outdoor Fabrics BV. The idea is to develop a model that will define the comfort for tent applications. At present, there is no single test procedure/ measurement technique that defines comfort. The project will start with defining comfort, in a later stage we need to translate in-use properties of tent fabric with material properties. For this assignment, you will perform a research about comfort: how can it be derinend, how can it be tested. in The student will work with actual tent fabrics and make testing protocol with wellestablished measurements techniques.

CLEANING DOORMAT Moisture absorptionn entrance mats This project is in collaboration with Rinos BV, a producer of high-performance entrance mats. Water, sand, fats, oils and other dirt is absorbed by entrance mats to keep buildings clean and safe. Rinos already developed a test method to compare entrance mats in their sand absorption properties. However, a test method to compare entrance mats in terms of water absorption, does not exist yet. Insufficient water absorption can lead to dirty and slippery floors. Purpose of the project is to develop a representative test method, to measure moisture absorption properties of entrance mats. The student will conduct several experiments on different types of carpet samples, with the purpose to develop a representative test method, to measure moisture absorption of entrance mats. Next to the test method development, also a research to improve moisture absorption of the carpets will be part of the project. Reprinted May 18, 2017, from: http://rinos.nl/en/product.
