| POLYZYME - LT consists of stabilized thermostable alpha amylase prepared by deep tank fermentation of Bacillus spp. It can be used for removal of starch based sizes from fabric, garments and other cotton made articles. Ideal also for desizing of the cotton-synthetic blends. Materials sized with starch derivatives or the starch blends with PVA or other chemicals can also be effectively desized with POLYZYME - LT. |

| APPLICATION NOTES |
| Process temperature |
: 30 - 350C |
| Ph |
: 6.5 |
| Dose |
: 5 - 8 gm POLYZYME – HT per kg fabric weight. |
| Liquor Ratio |
: 1: 10 |
| Batch Time |
