Polyester production exceeds silk by orders of magnitude; natural silk remains a small but premium segment in textiles (industry context) [8]

The global apparel industry market size for textiles is vastly larger than silk; silk is mainly niche and premium (industry context) [9]

Silk is composed of structural protein fibroin with sericin as the coating on natural filament [22]

Fibroin contains repeating amino acid motifs (notably glycine and alanine-rich sequences) that contribute to silk’s strength and crystallinity [23]

Sericin is a water-soluble protein gum that is removed during degumming to improve softness and textile performance [22]

Silk exhibits high tensile strength relative to its weight; engineering references cite silk as one of the strongest natural fibers [24]

Silk has good elasticity and can stretch significantly before breaking compared with many brittle fibers (property summary) [24]

Silk’s moisture absorption contributes to comfort and breathability; textile science references quantify that silk is moisture-regulating [2]

Silk has a natural sheen due to light reflection from its fibroin microstructure; textile references describe this optical property [2]

Silk is biodegradable and biocompatible due to its protein nature; biomedical materials summaries describe this [24]

Silk fibroin is used in biomedical applications (e.g., wound dressings, sutures) because of biocompatibility; references summarize this [24]

Silk can be processed into regenerated silk fibroin (RSF) films/scaffolds for drug delivery; biomedical literature cites it [25]

A published study (e.g., Nature Communications) reports that regenerated silk fibroin supports cell growth and is used for tissue engineering scaffolds [26]

The Bombyx mori silk fibroin has beta-sheet crystals that contribute to mechanical properties; materials reviews state this [27]

Silk fibroin films can exhibit water contact angle in a measurable range depending on processing; a materials paper reports a specific contact angle range [28]

Mulberry silk (Bombyx mori) cocoon is the most common commercial source of silk fiber [46]

Bombyx mori larvae feed primarily on mulberry leaves (Morus alba and Morus multicaulis) [46]

The mulberry silkworm lifecycle includes egg, larva (five instars), spinning, and pupal stages [46]

The silk filament is produced as a continuous thread during the larval spinning process [47]

Non-mulberry silks (e.g., Tussar/Antheraea) are produced from wild or semi-wild silkworm species; a key example is Antheraea mylitta for Tussar [46]

Antheraea mylitta (tussar silkworm) produces tussar silk (a major non-mulberry silk) [48]

The raw silk production requires reeling/winding cocoons to extract the filaments into silk threads [22]

Reeling converts filaments into single strands and multiple strands are combined into yarn using standard reeling practices (industry processing) [10]

Cocoon cooking/softening is used before reeling to loosen the filament ends (degumming/cooking) [10]

Degumming/sericin removal is a necessary step to obtain silk from raw filament for most textile uses [22]

Typical silk degumming removes sericin (the gummy coating) to leave fibroin as the principal structural protein [22]

Silk fibroin is mainly composed of glycine, alanine, and other amino acids; this protein chemistry underpins silk properties [24]

Bombyx mori silk has a characteristic protein fibroin with sericin coating [23]

Silk cocoon shell percentage (silk content in cocoon) is often reported as the cocoon shell weight fraction; industry guides provide typical ranges used for yield calculation [10]

Cocoon yield and reeling yield are commonly used metrics: “reelable cocoons” and “raw silk yield” are tracked in sericulture extension materials [10]

Silk reeling yield is the proportion of silk obtained from cocoons; this is a standard metric in cocoon processing manuals [10]

Cocoon shell filament length can be converted into denier/titer during reeling; sericulture manuals describe measuring filament length and reelability [10]

Cocoon cooking temperatures and time are specified in standard reeling protocols to loosen filament ends prior to winding [10]

Spun silk is produced from shorter fibers by carding and spinning; this is distinct from filament silk reeling [49]

Weaving and knitting are main processes for turning silk yarn into fabrics; loom types vary by end-use [2]

Silk yarn can be woven in different thread counts and fabric weights; typical labeling uses denier/tex metrics [50]

Silk production includes sorting cocoons by size and reelability; sorting practices are included in sericulture guidelines [10]

Cocoon shell ratio and floss content are used to evaluate cocoon quality before reeling [10]

Filament fineness and number of filaments per strand are measured in reel yarn quality control [10]

The FAO sericulture manual describes the “steps of cocoon reeling” as sorting, cooking/softening, reeling, winding, and drying [10]

Degumming uses water/alkali processes to remove sericin; parameters are defined in processing manuals [10]

Silk finishing includes dyeing and washing to achieve color fastness and hand feel; finishing steps are detailed in textile finishing references [10]

Silk throws/construction (weaving) affects fabric drape; textile construction rules are given in textile engineering texts [2]
