ONGOINGINNOVATIONSINFABRICMATERIALSFabrics are typically made of natural or man-made fibers. Global fiberconsumptiongloballywasestimatedat95.6milliontonsin2015,accordingtoLenzingAG.Syntheticfibers–themajorityofwhicharepolyesterfibers– comprise the largest share at 62.1%, followed by cotton with a 25.2%share, according to a report by Lenzing AG, a leading manufacturer ofsyntheticfiber.

Many other innovations in fabric materials have emerged over the pastcouple of decades as well, from heat insulating to water-proof fabrics,creatingnewpossibilitiesinappareldesignandproduction.
Inthisreport,welookbio-basedsyntheticsandsyntheticspidersilk.
BIO-BASEDSYNTHETICSThe main difference between bio-based synthetics and conventionalsyntheticsliesintherawmaterialsused.Bio-basedsynthetics,asthenamesuggests,aremadefrombio-basedrawmaterialssuchassugarcane,cornsugars and agricultural waste. Conventional synthetics such as polyester,nylon and acrylic use raw materials derived from fossil fuels such aspetroleum,naturalgasandcoal.

SYNTHETICSPIDERSILKSpider silk is regardedasoneof nature’swondermaterials becauseof itsextraordinary mechanical properties. It is tougher than Kevlar – a high-strength synthetic fiber used in racing tires and body armor – and has acomparabletensilestrengthtohigh-gradealloysteel,butismuchlighter.

The first reference to the use of spider silk dates back to the early 18thcentury inFrance,whereattemptsweremadetouse it tomakestockingsandgloves.Massproductionforcommercialapplications,however,wasanobstacle for centuries.

BoltThreadsandSpiberInc.–TransgenicMicroorganismsThese two startups take a different approach to producing spider silk.Insteadofmodifyingthegenesofsilkwormstoproducethematerial, theyhave harnessed genetically engineered microorganisms to produce theproteinthroughfermentation,whichservesastherawmaterialtomakethesyntheticspidersilk.Themaindifferencebetweenthetwostartupsisinthemicroorganisms they use – Bolt Threads uses genetically modified yeast,whileSpiberusesgeneticallymodifiedE.colibacteria.

IMPLICATIONSFORTHEAPPARELINDUSTRY
GrowingTrendinFiberInnovationSyntheticfibers,aninnovationfromthepastcentury,accountforoverhalfof global fiber consumption. However, as synthetics are produced frompetroleum-basedmaterial, the finite supply of petroleummeans that theproductioncostofsyntheticfabricscouldbesubjecttomarketvolatility.
More importantly, petroleum-based products leave a significant carbonfootprint during the production process. They are also not biodegradableandcausesignificantdamagetotheenvironment.Tinyfibersfromsyntheticfabrics also have the potential to poison the food chain. According to astudybytheUniversityofNewSouthWales in2011,microfibersmadeup85%ofman-madedebrisfoundonshorelinesaroundtheworld.
Consumers have become increasingly aware of a product’s sustainability,andthisisespeciallytrueamongmillennials.AscoveredinourGlobalRetailTrends for 2016 report,millennials place a higherweighting on corporateresponsibilityandsustainabilityintheirpurchasingdecisionsthandoothergenerations.
Syntheticfabricsubstitutes includebio-basedsyntheticsandprotein-basedspider silk, which are based on renewable resources such as plants andmicroorganisms. Water- and stain-resistant cotton fabrics also help topromotesustainability,astheycanreducethewaterandenergyusedinthewashingprocess.
ManagingtheCostBarriersNew innovations involve investment in R&D, and, inmost cases, a highermanufacturing cost. For example, the production cost of synthetic spidersilkis$100/kgwhilethethresholdpriceformassadoptionisUS$20-30/kg,according to estimated figures from Spiber.
