1. INTRODUCTION

Textileengineeringhasincreasinglybecomeavitalfieldin healthcare and public safety, where fiber science and microscopic analysis play a central role. From medical compressionbandagesusedintreatingvenouslegulcersto protectivefacemasksdesignedtoreduceviraltransmission,

the performance of these products is closelylinked to the microstructure of the fibers. Characteristics such as fiber orientation,porosity,andmechanicalbehaviorsignificantly affecttheireffectiveness,durability,andusercomfort[1,2].

Inthecaseofcompression bandages,researchshowsthat thedesignofwovenstructuresandthetreatmentofyarns are crucial in achieving the desired therapeutic pressure. Advancedtechniques,includingspectroscopicanalysis,have beenusedtoevaluatebandageporosityandpredictoptimal tensionlevels[3].Whenexperimentalfindingsarecompared with theoretical predictions based on Laplace’s law, noticeabledifferencesareoftenobserved,highlightingthe complex nature of textile behavior under practical conditions [1]. Materials such as cotton and viscose-lycra exhibitdifferentloadandelongationcharacteristics;cotton tends to generate higher pressure but may lead to fluctuations during movement [2]. Innovations such as double-weft constructions and the incorporation of silver nanoparticle-treated yarns demonstrate how fiber-level modificationscanenhanceantimicrobialperformanceand supportwoundhealing[4].

Similarly,thedevelopmentofprotectivefacemasksduring theCOVID-19pandemichighlightedtheimportanceoftextile fiberstructureinfiltrationefficiencyandsafety.Guidelines fromtheWorldHealthOrganizationemphasizetheroleof proper material selection and multi-layer construction in effectivemaskperformance[5].Microscopicstudiesreveal that fiber morphology, pore size distribution, and surface treatments directly influence a mask’s ability to trap particleswhilemaintainingbreathability[6].

Materials such as electro spun nanofibers, melt-blown polypropylene, and spun bond nonwovens have been extensively studied for their filtration capabilities at the nanoscale [9,12]. While nanofiber-based layers offer high surfaceareaforparticlecapture,theymayfacelimitationsin mechanical strength and durability. Hybrid structures combiningmicro-andnanofibers,particularlyinmodified melt-blownfabrics,haveshownimprovedperformanceby enhancing filtration pathways while maintaining user comfort[10].

antiviralpolyester,andsilkmasks providedeeperinsights intotheirstructuralandmechanicalproperties.Techniques such as scanning electron microscopy (SEM), pore size analysis,andtensiletestingshowthatmulti-layeredmasks like FFP2 and FFP3 achieve filtration efficiencies of up to ~98% due to dense fiber arrangements and reduced porosity [7,8]. However, this often comes with reduced mechanicalflexibility.Incontrast,cottonandsilkmasksoffer more uniform fiber orientation and better breathability, whileantiviralpolyestermasksincorporatetreatmentssuch assilverchlorideforself-sanitizingproperties[4,6].

Taken together, these studies emphasize a common principle:themicroscopiccharacteristicsoffibersformthe foundation for designing effective medical and protective textiles. Whether used for therapeutic compression or respiratory protection, these materials must balance performance, durability, and comfort. Advances in microscopy fromSEMimagingtospectroscopic porosity analysis enable precise characterization of textile structuresandguideinnovationsinyarnengineering,fabric construction, and multi-layer design [10,11]. Ultimately, textile science plays a transformative role in healthcare, wheremicroscopicfiberbehaviortranslatesintoimproved patientoutcomesandenhancedpublicsafety.

1.1 Development of the Novel Textile Microscope Using 3D Printing Technology

The development of the novel textile microscope was accomplished using advanced additive manufacturing techniques,involvingtheprecisefabricationandassemblyof 32individualcomponents.Theprintingprocesswascarried out using the Anet ET4 Plus (Model 84 Plus 1850, China), selected for its capability to deliver high dimensional accuracyandreliabilityin producingintricate geometries. The complete design was initially conceptualized and validated within a computer-aided design (CAD) environment, where each component was meticulously dimensioned and verified to ensure proper alignment, tolerancecontrol,andfunctionalintegration.

Following validation, the finalized CAD model was exported to Ultimaker Cura (version 5.10.2), which was employed as the slicing platform to generate machinereadable instructions (G-code) for the printing process. Material selection was carefully considered, and PLA (polylacticacid)waschosenduetoitsfavourableproperties, includingbiocompatibility,easeofprocessing,andadequate mechanicalstrengthforstructuralcomponents.

Toachieveoptimalperformance,theprintingparameters weresystematicallyoptimized.Ahighinfilldensityof90% wasimplementedusingahoneycombpattern,providinga balancebetweenstructuralstrengthandmaterialefficiency. Thelayerthicknesswasmaintainedat0.1mmtoensurefine resolution,smoothsurfacefinish,andaccuratereproduction ofmicro-scalefeatures.Buildplateadhesionwasmaintained

at 100% throughout the process to eliminate risks of warpingordetachment.Notably,the designwasexecuted without the need for support structures, reflecting the efficiency of the CAD optimization and print orientation strategy.

The resulting device was a fully functional textile microscope, fabricated with high fidelity to the original designspecifications.Thisworkdemonstratesthepractical feasibility of utilizing 3D printing technology for the development of advanced scientific instrumentation. Furthermore,theapproachhighlightssignificantadvantages over conventional commercially available microscopes, includingreducedmanufacturingcost,enhancedportability, and the ability to customize design features for specific textileanalysisapplications.
