Dyadic International, Inc. is a global biotechnology company with the
groundbreaking technology that brings nature to the marketplace. Dyadic
is focused on the discovery, development, and manufacturing of novel
products derived from the DNA of complex living organisms - including
humans - found in the earth's biodiversity.
Using its integrated technology platform, Dyadic develops biological
products such as proteins, enzymes, polypeptides and small molecules for
applications in large segments of the agricultural, industrial,
bioenergy, chemical and biopharmaceutical industries. By utilizing a
proprietary host organism, Dyadic's "one-stop shop" technology rapidly
discovers and expresses eukaryotic genes the genes of complex living
organisms and then manufactures those unique biological products for
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, Dyadic discovers, develops, manufactures and markets a
full range of products to meet your enzyme needs for the manufacturing
Stonewashing with pumice stones started out exactly as it sounds:
fabric was washed with stones. Before the development of cellulases,
stonewashing involved a lot of pumice rock tumbling around in a washer
with denim garments. Since the innovation of cellulase, the stonewashing
cycle time has been cut in half when used in conjunction with pumice
stones, as recommended by Dyadic. Additionally, stonewashing with
cellulase is superior to washing with pumice alone because it increases
garment softness and results in higher levels of fabric abrasion.
When originally developed, cellulase was an acid enzyme with a pH
level of about 5. Acid cellulase is aggressive, and although it produces
high levels of abrasion, it also reduces the fabric's tensile strength
and results in a high amount of re-deposition, or backstaining.
Neutral cellulase with a typical pH of 6.5 does not reduce the
fabric's tensile strength or backstain as severely as acid cellulase
does. However, neutral cellulase is not as aggressive as acid cellulase
and typically commands a higher market price. Dyadic's proprietary
neutral cellulase enzymes (US Patent #5,811,381 & US Patent #6,015,707)
provide unique attributes, as well as brightness and contrast, to denim
To meet the industry's demand for stonewashing, Dyadic is developing
additional varieties of enzymes to improve upon existing finishing
processes. A partial list includes laccase, polyesterase, cold water
Another enzyme commonly used by the textiles industry is amylase, the
first enzyme innovated to remove the starch warp sizing from fabric.
Warp sizing protects the warp yarn with a coating of starch that
minimizes yarn breakage during weaving. Although warp sizing is useful
in weaving, it leaves fabric stiff to the touch. Amylase also known as
amylose is used to remove the starch, leaving fabric softer and ready
for the consumer. Dyadic offers powdered amylase that is ready to mix
into liquid for use.
Cellulases are also used in biofinishing for the removal of surface
hairs from garments for increased comfort and fashion. The use of
cellulose also provides a softer feel to the fabric, especially to
man-made fabrics that can feel rough if not properly treated. TENCEL, a
popular fabric produced from wood pulp, could not gain market share
without biofinishing treatment because of its stiff fibers which result
in an uncomfortable effect.
From amylase to cellulase, the uses for enzymes in textiles continue
to grow. Catalases can be used to remove peroxide after bleaching to
improve the dyeing process. Pectinase can be used as a bioscour an
environmentally friendly alternative to caustic scouring.
With Dyadic's novel ability to screen for and produce new proteins,
innovative uses for enzymes in the textiles industry are limitless.
