These auxiliaries are commonly used to enhance body, fullness, or rigidity in fabrics, particularly for garments and home textiles. Traditional stiffeners often include synthetic polymers or formaldehyde-releasing resins, posing health and environmental risks. Contemporary alternatives prioritize bio-based sources like starches, celluloses, and biodegradable resins. These offer comparable performance while reducing dependency on petrochemicals and improving end-of-life outcomes for treated textiles. B2B sourcing networks are instrumental in helping brands and mills transition to compliant, low-impact options that maintain desired fabric properties without compromising sustainability goals.
