2.5.2 Apparent properties of FP emulsion
The apparent properties of the FP emulsion were determined via simple observations and tests.
2.5.3 Zeta potential and particle size
Zetasizer Nano ZS particle size analyzer (Malvern, UK) was used to measure the zeta potential, particle size, and the distribution of the FP emulsion. The particle size range of the microsphere was 5– 10 µm, and the microspheres should have good stability in the emulsion without coagulation.
2.5.4 Thermal property analysis
5 mg FP emulsion film sample was weighted, and the thermal property was analyzed using a Q500 thermogravimetric analyzer (TGA) (TA Co., USA), in the temperature range 30–80 °C at a heating rate of 10 °C/min in nitrogen atmosphere.
2.5.5 Atomic force probe scanning microscope (AFM) observation
Small amount of FP …show more content…
The samples were cut into 200 mm×50 mm size and standard raw cotton fabric with square size (50 mm×50 mm) was coated on the rubbing head and moved with a reciprocating stroke distance of 100 mm along the length of the samples. The contact angles between the fabrics and n-hexadecane were measured after 50, 100, 200, 500, and 1000 times of rubbings.
2.5.10 Washing resistance measurements
AATCC1993WOB standard detergent was selected (refer to JISL0217-79103 washing method) with a concentration of 2 g/L, a bath ratio of 1:40, water temperature of 30 °C and time of 5 min. Then, the samples were washed with flowing water twice for 2 min. After dehydration, one washing process was completed. After washing for 5, 10, 15, 20, 25, and 30 times, the samples were dried in an oven, and the contact angles of the fabrics with n-hexadecane were measured.
2.5.11 Breathability, whiteness, breaking strength and anti-ultraviolet performance measurements of the
