Lint-Loss and Appearance-Change Tests for Blankets

Abstract

Several textile-abrasion instruments were investigated for their ability to simulate the general surface appearance and lint loss of blankets developed during laundering and actual use. An Accelerotor-type abrasion instrument was the most effective in this regard for a wide range of representative 'blanket constructions and fiber types used by consumers. A 25-second Accelerotor exposure produced simulations of blanket surface appearances comparable to those developed during use. A nomograph was produced from correlations of the lint deposited in the dryer during latindering of the blankets and lint generated by a separate, Accelerotor test. The nomograph predicts the lint deposited in the dryer per laundering from the Accelerotor lint test for all representative blanket types evaluated. This simulated performance test rapidly determines the properties that consumers readily recognize during use and care of blankets and may be useful as a basis for blanket pricing.
