Consumers can now improve clothing

Area of Science:

  • Textile science
  • Photoprotection
  • Consumer science

Background:

  • UV protection factor (UPF) assessment is established.
  • Factors influencing UPF include fiber type, color, and construction.
  • Low-cost UV meters offer accessible measurement options.

Purpose of the Study:

  • To explore consumer-level improvements in textile UV protection.
  • To investigate methods for enhancing UV-protective properties of fabrics post-manufacturing.
  • To evaluate the efficacy of laundry-based UV absorber applications.

Main Methods:

  • Application of UV absorbers during laundry cycles (wash, rinse).
  • Testing UV transmittance and calculating UPF of treated fabrics.
  • Comparison of UV absorber effectiveness in detergents, laundry additives, and fabric conditioners.

Main Results:

  • A thin, bleached cotton swatch (UPF 3) achieved UPF >30 after ten washes with a UV absorber detergent.
  • UV protection improvement exceeded that of traditional dyestuffs.
  • A single wash cycle with a higher concentration laundry additive yielded similar results.
  • Rinse cycle fabric conditioners also demonstrated effectiveness.

Conclusions:

  • Laundry processes offer a novel and effective method for consumers to enhance fabric UV protection.
  • UV absorbers integrated into laundry products provide significant UPF improvement.
  • The Skin Cancer Foundation's "Seal of Recommendation" may validate these improved laundry products.
