"Water-Repellent and UV-Resistant Properties of Polyester Fabric ...", https://pmc.ncbi.nlm.nih.gov/articles/PMC12138703/. Nylon fibers demonstrate water-resistant characteristics due to their low moisture regain rate (typically 3-5%) and hydrophobic polyamide molecular structure, properties retained in recycled nylon materials. Evidence role: mechanism; source type: research. Supports: confirms that nylon (polyamide) fibers exhibit inherent water-resistant properties due to their molecular structure. Scope note: Water resistance refers to the fiber's inherent properties; actual bag performance also depends on fabric weave density and any additional treatments applied. ↩

"Occurrence, toxicity and remediation of polyethylene terephthalate ...", https://pmc.ncbi.nlm.nih.gov/articles/PMC8755403/. RPET (recycled polyethylene terephthalate) production reduces energy consumption by approximately 30-50% and greenhouse gas emissions by up to 60% compared to virgin polyester manufacturing, according to lifecycle assessment studies. Evidence role: general_support; source type: research. Supports: confirms environmental advantages of RPET compared to virgin polyester production. Scope note: Environmental benefits depend on collection systems, recycling processes, and transportation distances; RPET still involves synthetic material with end-of-life disposal considerations. ↩

"Screen Printing of pH-Responsive Dye to Textile - PMC", https://pmc.ncbi.nlm.nih.gov/articles/PMC8915174/. Screen printing on textiles achieves high durability through ink penetration into fabric fibers and heat-curing processes, typically withstanding 40-50 industrial wash cycles when properly applied with appropriate ink formulations. Evidence role: mechanism; source type: research. Supports: explains durability characteristics of screen printing on textile substrates. Scope note: Durability varies significantly based on ink type, curing method, fabric substrate, and usage conditions; the rating reflects optimal application conditions. ↩

"Economies of scale - Wikipedia", https://en.wikipedia.org/wiki/Economies_of_scale. Manufacturing unit costs decrease with order quantity due to fixed setup costs (tooling, sampling, quality setup) being amortized across more units, a principle known as economies of scale in production economics. Evidence role: mechanism; source type: education. Supports: explains the economic relationship between order quantity and unit cost in manufacturing. Scope note: This explains the general economic principle; the magnitude of price reduction varies by product type, manufacturing process complexity, and supplier cost structure. ↩

"Special Documents - International Trade Administration", https://www.trade.gov/special-documents. Import regulations in many jurisdictions require specific product certifications (safety, material composition, testing standards) for textile consumer goods; absence of required documentation can result in customs delays, additional inspections, or entry denial. Evidence role: general_support; source type: government. Supports: confirms that product certifications affect import compliance in international trade. Scope note: Specific certification requirements vary significantly by destination country, product category, and intended use; this describes general compliance principles rather than specific regulatory requirements. ↩
