Blue Desizing Enzyme ZD-121

1. Brief  introduction

The blue desizing enzyme ZD-121 is a new enzymic preparation with high thermal stability and effective compound. It is a special enzyme for denim desizing. The ZD-121 is used for desizing starch, starch derivatives and starch/PVA on fabrics. With strong decomposition ability for starch and part of PVA, the ZD-121 can quickly convert starch into dextrin, which is easily removed in the subsequent elution process. As a denim desizing enzyme, it has the basic bluish color-light characteristics.

2.Basic traits:

Chemical composition: amylase, surfactant

Appearance: brown liquid

Density: (23 °C) 1.1 g/cm3

pH: (23 °C) 6.5-7.5

3.Characteristics and advantages:

☆     The effect is most obvious in low and moderate temperature.

☆      It is suitable for various processes, including suction, cold pad-batch and steaming.

☆     It is suitable for the desizing of denim fabrics. Its blue light feature makes the denim’s color bright.

☆     It is suitable for all operating conditions between 35-65℃. The pH value of desizing fluid should be kept between 6.5 and 7.5. No salt is needed.

4.Application range:

It is suitable for removing starch size in fabric pretreatment. It can be diluted in any proportion of cold water. In order to ensure the complete desizing of fabric, the wetting agent, detergent, scouring agent or solvent can be used together with DJ-121 to enhance penetration and swelling of size and promote the cracking of long molecular chains. At the same time, it is helpful to remove wax, lime soil, PVA and synthetic size. It is very sensitive to heavy metal ions, oxides, high concentration of acid and alkali. The anionic wetting agent and scouring agent can affect enzyme activities.
