研究目的
To investigate the effect of TiO2 pigmented coatings on spectral reflectance and color performance of white and colored polyester fabrics in UV, VIS, and NIR region of electromagnetic spectrum.
研究成果
The study reveals that TiO2 nanopigment significantly affects the spectral reflectance and color performance of polyester fabrics, with particle size playing a crucial role in determining the extent of impact in different regions of the electromagnetic spectrum. The findings provide valuable insights for the development of functional textiles with desired optical properties.
研究不足
The study focuses on the effect of TiO2 nanopigment on polyester fabrics, and the findings may not be directly applicable to other types of fabrics or pigments. The experimental conditions and concentrations used may also limit the generalizability of the results.
1：Experimental Design and Method Selection:
Polyester fabrics were coated with TiO2 nanopigment with various concentrations and different diameters, and their reflectance spectra were measured using spectrophotometric method. Two-way analysis of variance (ANOVA) was utilized to investigate the significance of the effect of TiO2 nanopigment on the color performance of coated fabrics.
2：Sample Selection and Data Sources:
100% taffeta woven polyester fabrics were selected as substrate fabric. Titanium dioxide with average particle size of 35, 120, and 250 nm and with the rutile crystalline structure was used.
3：List of Experimental Equipment and Materials:
FESEM images taken by MIRA3 TESCAN, Color-Eye 7000A spectrophotometer, SPECORD 250-222P168 spectrophotometer.
4：Experimental Procedures and Operational Workflow:
Fabrics were dyed using pad-thermosol method, then coated with TiO2 nanopigment, followed by drying and curing processes.
5：Data Analysis Methods:
Reflectance spectra and colorimetric data were analyzed to assess the impact of TiO2 nanopigment on the optical properties of the fabrics.
