SARABLOOM-2951 |

Colour deepening agent for Polyester

Sarabloom-2951 is special colour blooming agent developed for enhancing the shade of synthetics like polyester, polyamide and their blends dyed with black and navy blue dyes. It also gives colour blooming effect on wool and their blends. Fabric treated with Sarabloom-2951 exhibits exceptionally high depth on the fabric with bluish tone. It can be added in normal finishing recipe with other softeners.

SUGGESTED RECIPES

Substrates	Concentration	Colour depth*
Polyester	30-40 g/l	25-45%
Micro polyester	20-30 g/l	20-40%
Polyamide	20-40 g/l	20-40%
Wool and its blends	20-30 g/l	20-40%

*Increase in colour depth depends upon type of dye and substrate.

Note :

• Sarabloom-2951 can be applied along with 15-20 g/l Macrosoft-W to get better softness.
• Curing at 150-170 deg.C for 2-3 min for improving durability to washing.
• It is recommended to use 2-5 g/l Antistat-CD (antistatic agent) with Sarabloom-2951 on polyester fabric.

Precautions :

• Any strong mechanical finish like calendering, pressure decatising etc. which can affect the surface characteristics of the finished fabric may reduce blooming effect.

  Please note that after finishing with Sarabloom-2951, treated fabric needs to be dried immediately on stenter without any mechanical or manual contact. To avoid possible nail mark, dried fabric need not be touched in the interim period i.e. the period between finishing and drying.

• Sarabloom-2951 is slightly prone to thermo-migration of dye which may lead to lower rub fastness of finished fabric depending on various factors.

• pH of padding solution should be 4.0-4.5 If pH increases to alkaline side then emulsion becomes unstable resulting in the formation of white specks and ultimately lower colour blooming effect.

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.

Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
