Abstract:

The paper presents an investigation of the resistance to pile loop extraction of terry fabrics in relation to the pile height, impacts/finishing, and weft density. Terry fabrics analysed in the experimental work were made from linen/cotton or ramie/cotton yarns. The pile height of the fabrics was 6 and 12 mm, and the weft density varied from 80 to 200 dm-1. The samples were affected by impacts or finishing operations. Grey fabrics were also investigated. Analysing a 10 mm pulling distance, the highest resistance to pile loop extraction of grey terry fabrics (1064.2 mN) was determined for linen/cotton fabric with a 6 mm loop pile. It was found that an increase in the weft density of ramie/cotton terry fabrics from 80 to 160 dm-1 led to an increase in the resistance to pile loop extraction for all pulling distances investigated but with a different intensity: for a 5 mm pulling distance the difference was 3.2 times, and for a 25 mm pulling distance it was in 2.1 times. The decrease in the resistance to pile loop extraction of 18.6 - 38.0% of industrially finished and tumbled linen/cotton fabrics compared with grey ones was determined at a 10 mm pulling distance. The changes in the resistance to pile loop extraction in relation to the tumbling period were not statistically significant.
