TSF-4708

TSF4708 is an amino-functional silicone fluid developed for textile softener use. It can be easily emulsified to stable microemulsions, which give durable softness and smoothness to cotton, blending cotton woven fabrics and knitted products.

KEY PERFORMANCE PROPERTIES:

• Good affinity for fabrics.

• Easy to formulate.

• Imparts durable softness to many fabrics.

APPLICATIONS:

• It gives excellent softness and low-yellowing properties to a variety of fabrics.

EMULSIFICATION INSTRUCTIONS

15% Silicone Microemulsion (22.5% solid)

• Blend the following ingredients using an overhead stirrer.
• Slowly add 69.8 parts of ion-exchanged water (part two) with good agitation.
• Note: if desired, biocides may be added in this step.
• Slowly add 0.2 parts of acetic acid. Agitate well for 5-10 minutes to ensure homogeneity.
• Filter the emulsion to remove any dirt or undissolved gel particles. Fine filtration is not required.

AN EVALUATION RESULT:

 

Treating bath	:2% solid of above emulsion
Test fabrics	:Cotton woven,
Treating condition	:Padding (pick up 100% for Cotton) Drying (130°C 3min)
Evaluation of softness	:Pure Bending Tester (KES-FB2 : KATO TECH Co., LTD) Calculation value* = (B+2HB)/2 B=(Bwarp+Bweft)/2 2HB=(2HBwarp+2HBweft)/2 B : Bending rigidity (gf.cm2 /cm) 2HB : Hysteresis of B (gf.cm2 /cm)
Evaluation of smoothness	:Surface Tester (KES-FB4 : KATO TECH Co., LTD) MID** = average of kinetic friction co-efficient MMD***= variation of MIU
Yellowing	:Delta b value measured after 175°C, 30min by color differential tester based on untreated fabric color
