The Effect of Dry-Cleaning and of Laundering With and Without Fabric Softeners on the Thermal Properties of Blankets1

Abstract

The effects of repeated dry-cleanings and launderings with and without fabric softeners on the thickness, air permeability, dimensional stability, and thermal insulative properties of two blanket fabrics were evaluated in this study. One of the two softeners used in laundering was added to the rinse, and the other was added to the dryer. Changes in the thermal-transmittance properties of the test fabrics were determined with a guarded hot/cold plate. After repeated dry-cleanings and launderings, the blanket fabrics exhibited a significant reduction in thickness. Fabric dimensions were altered sifinificantly during the first few washings. Laundering and dry-cleaning also significantly changed the air permeability of the blanket fabrics: the permeability increased for one blanket fabric and decreased for the other. There was no significant change, however, in the thermal conductivity of the blanket fabrics after repeated launderings with or without fabric softeners or after repeated dry-cleanings. Thus, the thermal insulative properties of the blanket fabrics were not affected by repeated cleanings or by the use of fabric softeners during the washing or drying cycle of laundering. _ .le

Effects of coating of nano‐ and microemulsion silicones on thermal properties and flammability of polyethylene terephthalate textile

“…TGA is useful to measure the mass change, thermal decomposition and thermal stability of textile fibres. In other words, DMTA is widely used as a technique for investigating the structures and viscoelastic behavior of textile materials for determining storage modulus and loss factor (tan δ) (Wulf et al , 2010; Kotresh et al , 2006; Baker, 1979).…”

Thermal Characterization and Flammability of Polyester Fiber Coated with Nonionic and Cationic Softeners

“…These compounds can influence the flammability of such fabrics. In this regard, the flammability of softener finished polyesters used in garments needs to be considered as an important issue of human safety [15][16][17][18][19].…”
