ProChem continuously develops product line in order to have innovative enzymes with unique performance features for existing and new applications within the textile industry. ProChem provides a range of enzymes like amylases, cellulases, catalase and protease for various textile wet-processing applications like desizing, bio-polishing, denim finishing and bleach clean-up. 

For fabrics made from cotton or blends, the warp threads are coated with an adhesive substance know as 'size‘; to prevent the threads breaking during weaving. Although many different compounds have been used to size fabrics, starch and its derivatives have been the most common sizing agent. After weaving, the size must be removed again in order to prepare the fabric for dyeing and finishing. Desizing process must be carried out by treating the fabric with chemicals such as acids, alkali or oxidising agents. However starch breaking enzymes (amylases) are preferred for desizing due to their high efficiency and specific action. Amylases bring about complete removal of the size without any harmful effects on the fabric. Another benefit of enzymes compared to strong chemicals mentioned above is that enzymes are environment friendly. 

Cotton and other natural fibres based on cellulose can be improved by an enzymatic treatment known as Bio Polishing. This treatment gives the fabric a smoother and glossier appearance. The treatment is used to remove 'fuzz' - the tiny strands of fibre that protrude from the surface of yarn. A ball of fuzz is called a 'pill' in the textile trade. After Bio Polishing, the fuzz and pilling are reduced. The other benefits of removing fuzz are a softer and smoother handle, and superior colour brightness.

Denim Finishing
Many garments are subjected to a wash treatment to give them a slightly worn look; example is the stonewashing of denim jeans. In the traditional stonewashing process, the blue denim was faded by the abrasive action of pumice stones on the garment surface. Nowadays, denim finishers are using a special cellulase.

Cellulase works by loosening the indigo dye on the denim in a process know as 'Bio-Stonewashing'. A small dose of enzyme can replace several kilograms of pumice stones. The use of less pumice stones results in less damage to garment, machine and less pumice dust in the laundry environment.

Bio Stonewashing has opened up new possibilities in denim finishing by increasing the variety of finishes available. For example, it is now possible to fade denim to a greater degree without running the risk of damaging the garment. Productivity can also be increased because laundry machines contain fewer stones or no stones and more garments.

ProChem offers a range of cellulases for denim finishing, each with its own special properties. These can be used either alone or in combination with pumice stones in order to obtain a specific look.

Bleach Clean-up
Natural fabrics such as cotton are normally bleached with hydrogen peroxide before dyeing. Bleaches are highly reactive chemicals and any peroxide left on the fabric can interfere with the dyeing process. A thorough 'Bleach Cleanup' is necessary. The traditional method is to neutralize the bleach with a reducing agent, but the dose has to be controlled precisely. Enzymes present a more convenient alternative because they are easier and quicker to use. A small dose of catalase is capable of breaking down hydrogen peroxide into water and oxygen. Compared with the traditional clean up methods, the enzymatic process results in cleaner waste water or reduced water consumption. ProChems offer catalase for removing residual hydrogen peroxide after the bleaching of cotton. It reduces the rinsing necessary to remove bleach or it can be used to replace chemical treatments.
