Save energy in production. Make fabrics softer. From stonewashing to biofinishing and next-generation processes, Dyadic uses enzymes to create comfort in what we wear while benefiting the bottom line.

Stonewashing

In 1979, Dyadic pioneered the stonewashing process. Today there is a wide selection of cellulases available for the stonewashing of garments, including acids, neutrals, modified acids and hybrids. Modified acids and hybrids tend to combine characteristics of acids and neutrals. Dyadic has developed a variety of these products, including acid (ACE series), neutral (NCE series), and modified acid (Antarctic series) cellulases.

Dyadic has also innovated two cold water cellulases, enabling the stonewashing process to take place at 40 degrees or below. By running at lower temperatures, Dyadic’s products create energy savings for textiles manufacturers, versus the traditional stonewash cellulases, which typically are run at higher temperatures. Dyadic’s ROCKSOFT™ Antarctic and Antarctic LTC cellulases and our FIBREZYME™ G4 are available as ready-to-use blends or as concentrated formulas.

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 provide unique attributes, as well as brightness and contrast, to denim wash.

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.

Biofinishing

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.

Biofinishing is the use of cellulase — typically acid cellulase — to remove surface hair from fabrics and garments. The garments may be hairy as a result of garment dyeing or other wet processing. Some fabrics tend to be hairy because of their construction. Fibers like Tencel are hairy by design, and fabrics or garments can be fibrillated and de-fibrillated to create new surface effects.

Dyadic has developed the BioACE series — specialized acid cellulases for the biofinishing of fabrics. For specialized effects or more fragile fabric, the use of a neutral cellulase like ROCKSOFT™ NCE-L600 is being utilized by numerous processors worldwide.

Next generation enzymes

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.

To meet the industry’s textile demands, Dyadic is developing additional varieties of enzymes to improve upon existing finishing processes. A partial list includes laccase, polyesterase, cold water biofinishing. With Dyadic’s novel ability to screen for and produce new proteins, innovative uses for enzymes in the textiles industry are limitless.
