Company Profile
A business-to-business biotechnology company carries no shop box, and its textile chapter is history: the stonewashing, biofinishing and enzyme-range record below is summarised here and kept in full on the history page, as the trade record of its period.
Its place in a fashion directory is the core business it started with: Dyadic's core business was initially focused on the textiles industry, providing jean manufacturers with the pumice stones needed for stonewashing denim garments. Building on the company's success with pumice, Dyadic added several chemical auxiliaries to its product line; enzyme manufacturing filled a need within the textiles industry by providing high quality acid and neutral cellulase enzymes at competitive prices. Today, as recorded, Dyadic discovers, develops, manufactures and markets a full range of products to meet enzyme needs for the manufacturing of textiles - and the rest of the original is a working explanation of those enzymes, which this page preserves in the next two sections because it is the most technically specific textile-finishing text in this letter.

The earlier record for this company - its history, past brand line-ups, figures and photographs from the periods described - is kept on a separate page for historical reference.
Dyadic International History & Historical Profile →Common Questions
Why is a biotechnology company in a fashion directory?
Because Dyadic's core business began in textiles: it supplied jean manufacturers with pumice stones for stonewashing denim, then built a textile enzyme line - acid and neutral cellulases, amylase, catalases and pectinase - for denim washing, desizing, biofinishing and scouring, in the historical record.
What is the difference between acid and neutral cellulase?
Acid cellulase (pH about 5) is aggressive, giving high abrasion but reducing tensile strength and causing more backstaining; neutral cellulase (typical pH 6.5) is gentler on strength and backstaining but less aggressive and typically higher priced. Dyadic's proprietary neutral cellulases are covered by US Patents 5,811,381 and 6,015,707, in the historical record.
What does amylase do in textile production?
It removes the starch warp sizing applied to protect warp yarn during weaving, which otherwise leaves fabric stiff - leaving the fabric softer and ready for the consumer. Dyadic offers it as a powder ready to mix into liquid, in the historical record.
