WORK MECHANISM

Cellulase is a kind of complex enzyme which consists of five different enzymatic subunits representing namely endocellulases, exocellulases, cellobiases, oxidative cellulases and cellulose phosphorylases wherein only endocellulases and cellobiases participate in the actual hydrolysis of the β(1→ 4) linkage. Recent work on the molecular biology of cellulosomes had led to the discovery of numerous cellulosome-related “signature” sequences known as dockerins and cohesins. Depending on their amino acid sequence and tertiary structures, cellulases are divided into clans and families.[4]Since the molecular weight of the cellulose is thousands of times of water, it can not penetrate into the cellulose fabric, only catalytic hydrolysis of cellulose fluff fabric surface, the fabric surface smooth, soft, fabric prickle improved, while does not result in the fabric strength over a limited decrease processing time.

UNIT DEFINITION

In (50 ± 0.1)°C, specified pH conditions (acid cellulase pH4.8, neutral cellulase pH6.0),1g solid enzyme (or 1ml liquid enzyme) has spent one hour to hydrolyze sodium carboxymethyl cellulose substrate and produced the reducing sugar as much as 1mg glucose. The amount of reducing sugars is a unit of enzyme activity .It is expressed by μ / g (or μ / ml) and abbreviated as CMCA-DNS.

USAGE METHOD

1.   Desize thoroughly.
2.   Drain liquor then fill machine to liquor ratio of 1:10. (jean/ water)
3.   Add pumice 0-0.5 kg, heat bath to 40-60°C and optimum temperature is 55°C.
4.   Add cellulose 1,000U/g at the rate of 0.25-1.0%.
5.   Adjust pH to 5.5-7.5 with pH 6.0-6.5 as an optimum.
6.   Process for 30-45 minutes depending on desired effect.
