Chitosan Applications and Dosage in the Textile Industry

Chitosan Applications and Dosage in the Textile Industry

Chitosan, a natural polysaccharide derived from crustacean shells, is widely used in textiles for its antimicrobial, moisture-wicking, and eco-friendly properties. It is applied in three main forms: fiber, powder, and solution.

In fiber form, chitosan is blended with cotton, polyester, or wool at 5–30% by weight. This integrates durability and breathability directly into the fabric, ideal for activewear and medical textiles.

As a powder, it is used in finishing processes at 1–5% owf (on weight of fabric). It is applied via padding or spraying to enhance antimicrobial effects and wash resistance.

In solution form, chitosan (1–3% w/v in 1–2% acetic acid) is used in pad-dry-cure methods. Standard parameters: 40–60°C for 20–30 minutes, followed by drying at <120°C. This is common for cotton and nonwovens.

Overall, typical dosages range from 1–5% owf for finishes and 5–30% for fiber blending. Chitosan meets the rising demand for sustainable, functional textiles in hygiene, healthcare, and sportswear.
