SIZING RECOMMENDED GRADE

SIZING RECOMMENDED GRADE

OPTISIZE low viscosity powder grades are specially recommended for unmodified starch or starches modified by simple techniques . They improve the yarn tension strength and extension and do not increase the viscosity of starch.

Typical recipes:

Optisize VLV – PLV with starch:

Yarn

Ne (Tex)

Ends/Inch

Optisize VLV – PLV

Starch

Wax

Target Size on yarn

Cotton:
30 (20) 80 2 – 2,3 5 0.5 8%
132 3 – 4 6 0.5 10%
50 (12) 130 3,5 – 4 7.5 0.5 12%
Polyster/cotton 65:
20 (30) 70 3 – 4 8 1.0 12%
30 (20) 75 4 – 5 9 1.0 14%
40 (15) 100 5 – 6 10 1.0 16%

The figures here above refer to kg per 100 litre ( lbs/10 gals) final volume of size liquor
