Note :

  • 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. period between finishing and drying.

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

  • pH of padding solution should be 4.5-5.0 If pH increases to alkaline side then emulsion becomes unstable resulting in the formation of white specks and ultimately lower colour blooming effect.

  • Make small volume of pad solution to avoid tailing problem.


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.
