Brief information
This product is neutral liquid pectate lyase, the enzyme belongs to the carbon-oxygen lyases in polysaccharides. By pectinase biorefining, the pectin can be efficiently hydrolyzed into soluble substances. In the biorefining process, is advantageously removed the cotton fabric and other impurities (such as wax and protein). At the same time enhance the wetness and water absorption of the cotton fabric surface.General properties
-- Appearance: Light yellow liquid-- pH: 5.5~6.2
Properties and fields of application
--Enzyme biological refining system can replace the traditional the scouring process which is under high alkaline pH and high-temperature operation.--With medium temperature operation that can save energy and costs. And reduces the possibility of the crease.
--Neutral pH process conditions that can improve fabric quality (softness, fluffy feel), reduce fabric weight loss, enhance water absorption and improve dyeing.
--Comply with the process requirements of current global green cotton spinning, ecologically friendly, human health and lasting development.
--Suitable for medium and dark color dyeing.
