Textile desizing auxiliary agents enzyme

Product highlights

An Alpha-amylase with excellent heat-resistance, ideal for desizing of textile fabrics incl. Cotton, silk, polyvinyl alcohol, rayon fiber, synthetic blended and yarn-dyed poplin:

1. Improve desizing rate to 90~95%, reduce desizing time

2. No damages to fabrics, make texture feels soft, full, smooth and bright

3. Enable desizing and colour-fixing at the same bath, thus reduce process flow and improve productivity

4. Enhance capillary tube effect of fabrics

5. Improve working conditions for operators

6. Save fuel energy and reduce processing cost

7. Adapted to consecutive mass production, boiling-off, steeping, washing and other special desizing process

Description

HS-200 is a thermostable Alpha-Amylase produced by a modified strain of Bacillus licheniformis. It is an endoamylase that hydrolyzes alpha-1, 4-glucosidic bonds to quickly reduce the viscosity of gelatinized starch, producing soluble dextrins and oligosaccharides.

HS-200 has excellent heat resistance, fits to desizing of textile fabrics such as cotton, silk, polyvinyl alcohol, rayon fiber, synthetic blended and yarn-dyed poplin.

Product Characteristics

Effect of pH

HS-200 is active over a wide pH range, depending on the application conditions. The optimal pH is 6.0~7.5. The stable pH range is 5.0~10.0 at 25°C(77°F).

Effect of Temperature

Optimum temperature of Boli HS-200 ranges from 85 to 110ºC.

Concentration of Calcium

HS-200 requires a very low calcium concentration. Addition of 50 to 70 ppm (DSB) of calcium is sufficient to ensure enzyme stability.

Inhibitors

Copper, titanium, and cobalt ions are moderate inhibitors for HS-200 whereas aluminum, lead and zinc ions act as strong inhibitors.

Liquid enzyme is often packed in 25kg plastic drums or 1125kg IBC Totes.
