Brief information
--It is a special biological enzyme, which belongs to carbon and oxygen lyase which acts on polysaccharide and can act on the pectin and cellulose in cotton fiber simultaneously.--It can be used in pectinase biological refining, and can also be used for polishing and finishing wool with cotton fiber.
--It is also possible to combine the polishing and finishing process of pectin enzymatic biorefining and cotton fiber. High-speed decomposition of pectin, remove other impurities (such as waxy and protein) from cotton fabric and make the fiber fabric permanent clean.
--Enhance the surface wettability and water absorption of cotton fabric and make the fabric have the anti-pilling function.
General properties
-- Appearance: yellow-brown 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.
Application
--It is an efficient enzyme preparation, and a wide range of application pH and temperature (see below figure). It is suitable for the biorefining pretreatment process of cellulose fiber.--Before joining the soft enzyme, first adjust the pH and temperature of working fluid to the requirements, adding enzyme and keep temperature and work for 60-90 minutes. When cut sample achieves biopolishing requirements then adding 2g/L soda and heating to 80℃ and inactivated. Then for the subsequent washing and dyeing process.
The specific process and operation parameters are as follows:
| Operating parameter | |
| Process parameters | Optimal range |
| pH | 6.0 - 6.5 |
| Dosage | 1.0-2.0%（o.w.f） |
| Temperature | 60 - 70°C |
| Bath ratio | 1:5 ~ 1:10 |
| Time | 60 - 80 min |
Traditional pretreatment process of alkaline scouring:
Pretreatment process of pectinase biological scouring:
Packing and storage
