1. Dissolving Pulp Science: From Sustainable Timber to Regenerated Filaments
Regenerated cellulose is a bio-based fiber engineered by reconstituting natural plant cellulose into continuous textile filaments:
- High-Alpha Wood Pulp Dissolution: Sustainably harvested softwoods and hardwoods undergo kraft cooking and multi-stage bleaching to isolate pure dissolving pulp with alpha-cellulose purity exceeding 92%.
- Controlled Xanthation & Extrusion: Pulp sheets are steeped in sodium hydroxide (NaOH) to form alkali cellulose, reacted with carbon disulfide (CS2) into sodium cellulose xanthate, and dissolved in dilute caustic soda to create viscose dope. This honey-viscous fluid is filtered, deaerated, and extruded through precision spinnerets into an acidic regeneration bath (H2SO4, ZnSO4, Na2SO4).
- Polymer Re-crystallization: Acidic neutralization converts xanthate back into pure cellulose II crystal structures, drawing the filament into continuous fibers with exceptional softness, uniform cross-section, and abundant micro-capillary pores.
2. Hydrophilic Surface Thermodynamics: The Physics of Spontaneous Oil Release
The extraordinary grease-releasing properties of regenerated viscose are governed by thermodynamic interfacial tension:
- Hydroxyl Group Density (-OH): Cellulose macromolecules feature three reactive hydroxyl groups per anhydroglucose unit. This exposes an immense density of hydrophilic hydrogen-bonding sites on the fiber surface, generating a high polar surface energy exceeding 42 mN/m.
- Formation of the Interfacial Hydration Layer: When the cloth is exposed to water, water dipoles bind instantly to the hydroxyl sites, establishing a stable, tightly bound microscopic hydration layer across the entire fiber periphery.
- Lipid Phase Displacement: Cooking oils, animal fats, and industrial greases possess non-polar, low surface energies. Because the interfacial tension between water and cellulose is drastically lower than that between oil and cellulose, water spontaneously displaces the oil droplet from the fiber surface, causing grease to effortlessly float away under running tap water.
3. Circular Knitting Engineering: Converting Delicate Cellulose into Heavy-Duty Textiles
While pure regenerated cellulose offers peerless cleaning chemistry, raw cellulose fibers experience an inherent 30% reduction in tensile strength when wet. Overcoming this physical limitation requires advanced circular knitting architecture:
- The 85/15 Filament Matrix: Wuxi Jiali utilizes a golden ratio blend: 85% high-grade regenerated plant viscose intimately coupled with 15% high-tenacity continuous filament polyester as an internal geometric skeleton.
- Three-Dimensional Loop Interlocking: Manufactured across industrial multi-feed circular knitting fleet, the yarns are formed into continuous interlocking weft loops. The polyester core bears mechanical tensile loads during wringing and scrubbing, while the outer viscose loop pile handles 100% of liquid absorption and grease entrapment.
- Overcoming Non-Woven Weakness: Unlike single-use spunlace non-woven wipes that delaminate under wet friction, our circular knitted matrix withstands hundreds of commercial laundry cycles without structural disintegration.
4. Bio-Enzyme Scouring & Finishing SOP: Achieving Infant-Safe Purity
Raw greige knitwear emerging from the knitting room contains spin finishes and mechanical lubricants that must be purged to activate high absorbency:
- Continuous Overflow Scouring: The tubular knit fabric undergoes multi-stage overflow scouring with biodegradable surfactants to remove all spinning oils and mineral lubricants.
- Bio-Polishing with Cellulase Enzymes: Controlled enzymatic bio-finishing hydrolyzes loose protruding surface fibrils, eliminating pilling and fuzz without degrading the base tensile structure.
- Eco-Reactive Dyeing & Rinsing: Dyed variants utilize heavy-metal-free, low-salt reactive dyes that covalently bond to the cellulose polymer backbone, achieving Japanese Daiei Grade 4.5 colorfastness and certifying zero chemical bleed into food-contact zones.
