MDSE 2650 Unit Exam 1Questions are from Lectures, iTextiles (readings, charts, videos, etc.), and Textile Kit Lab (you will not need to memorize swatches).Studying: 1. iTextile.com readings and videos 2. Your lecture notes and PDFs 3. Lab1 (you will not need your Texkit 4. iTextiles.com Interactive Study. Subjects include: Intro: why knowing textiles is importantoKnow what’s a textile and what isn’toTextile stages of manufacturing and definitionsoGreige goods, converting, coloration, finish and all vocabularyoMajor end Use categories & ExamplesoWhy is knowledge of textiles important?oProduct Development: textiles are selected based on end use; what criteria do we consider? Remember the in-class work: each was given a different product with specific end uses and had to state what the consumer expected from the product? oGlobal Textile Complex: an interconnected supply chain, what industries are involved?Is there a textile industry in the US?Performance & Careo4 categories are subjective: aesthetics, comfort, durability, safety/healthoProperties: are specific and measureable; know all the definitions of the terms and how they relate to the catergories; know how to use the terms when describing a textileEx: Aesthetic = luster (high level of luster might be described as shiny)How do we make properties objective? Testing.You do not need to know the names of the equipment used for testingoFabric Care: What determines the correct care? All components of a product, fiber propertiesWhy are care labels needed?Introduction to FibersoWhat is a fiber, generic vs. trade names, who decides the names todayoFiber classifications: what are they and what are they based on?oStaple vs. FilamentoFiber structure: importance, polymers, amorphous vs. crystalline—examples of fibers, what properties are visibleoFiber properties: definitions of properties, examples if described in classoSafety: Burning behavior of fiber classes and terminology Burn Test: which fiber smells like burning hair? This is both a video on iTextiles and Canvas, and a chart on iTextiles.oIdentifying fibers: why and how?Natural Fibers: oclasses (cellulose, protein, mineral); differences between classesoSubclasses of cellulosics/plant fibers, what are cellulosic fibers made ofoSubclasses of protein/animal fibersoWhat is common to all natural fibersCellulosics & Protein FibersoNames of the fibersoGrowth, processing, importance, grading, color, varieties if applicable (like organically colored cotton) unique characteristics including fiber contour and shape, performance highlights, end uses and care, sustainability positives and negatives, identificationoHow do we ‘engineer” natural fibers? Blend other fibers to achieve best properties of each fiber; converters may alter inherent properties by chemical treatments.This is not all-inclusive; there may be other subjects we covered.
