Final Year Project Proposal PresentationThe study of nonwoven textile for face maskOutlineIntroductionGoals and ObjectivesScopeMethodologyIntroductionNonwoven fabric is a sheet of fibers, continuous filaments or chopped yarns of any origin, that have been formed into a web means with the exception of weaving or knitting(Purdy, 1983).

Different properties are combined to create the required functionality, while achieving a profitable balance between the expected product life and cost (Wilson, 2004)

IntroductionSurgical face maskDeveloped in early 1900sAkalin (2010) analyses:Protect the virus, bacteria, biological substances and particles in the air. Prevent the wearers from being splashed in the mouth and body fluids or saliva.Reduce the chance of spreadingairborne diseases

Introduction

Material:Gauze TC fabric (Polyester/Cotton )NonwovenIntroductionSurgical face masks are used by the general public in heavily populated after SARS in 2003

Goals and ObjectivesTo investigate the properties of nonwoven

To investigate the effectiveness of nonwoven face mask

To investigate and evaluate a possible approach for face mask to increase its effectiveness in terms of design and materialScopeTypes of face masks(difference material)

Experimence of function

Design & Function of face maskEffectivenessFiltrationElectrostatic precipitation effectTextile thickness / fiber orientation density

Seal tightness

MethodologyQuestionnaire Problems/dissatisfaction of face mask

Subjective testExperimental Details:Standard testing conditions22C and 65% relative humidity

Objective test (human trail)

TestFiber orientation distribution/nonwoven structureElectron microscope

ThicknessASTM D5729-97 Standard Test Method for Thickness of Nonwoven Fabrics (Withdrawn 2008)

RepellencyISO 9073-13 Spray rating Test

ASTM F1862-00a Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Known Velocity)

TestFitting Testing

Seal tightness

The tightness of the seal is the critical factor determining whether a mask will be effectiveMethodologySample:5 different brands nonwoven and 2 different material (gauze, TC fabric) surgical face masks will be collected from the market

Analysis ResultUsing Excel and SPSS

Difference performance

Base on the problems of face mask, provide some possible designs to improve face masks performance
