BRATEX SIZE   F – 90

1. GENERAL PROPERTIES

Physical Form                           : Light brownish viscous liquid.

Active Content                          : 20 ± 1.0% by Refractometer

pH value                                                : 6.8 ~ 7.6

2. Stability

Solutions of F – 90 have good stability to hard water, but the product forms sparingly soluble precipitates with acids, polyvalent metal ions, e.g. calcium, magnesium, zinc and iron ions, and with cationic substances.

F – 90 need not mixing with the usual polyvinyl alcohol.

    

3. Climatic stability

F – 90 is not sensitive to moisture and can therefore be used without problems under the climatic conditions normally maintained for staple fibers.

4. Action

On drying, F – 90 forms a though, flexible film, which has excellent adhesion to polyester yarn and subsequently be readily washed out.

The high adhesive power of the product lead to an excellent sizing effect and weaving performance.

Warps that have been correctly sized with F – 90 give optimum   results on all types of weaving machines besides water jet loom.

5. Desizing

F – 90 itself can be readily washed out.

6. Application

The high adhesive power of F – 90 leads to an excellent sizing effect and weaving performance.
