Abstract:
For reducing the impact of fabric curling on downstream processing, the organization of different structures and the choice of draw off densities were discussed in this paper. 55.5 dtex 24f fully drawn polyester yarn was used to produce two guide bar warp-knitted fabrics with seven different structures and four different draw off densities. Then curling distances were tested and the curling reasons were analyzed through the microscope. The results showed that with the increase of draw off density, the wale and course-wise curling distance of fabric are decreased, and the effect of draw off density on course-wise curling distance is significantly greater than that of wale-wise;The course-wise curling distance of two guide bar with same direction lapping is better than that of reverse lapping; When the structure of the first guide bar remains unchanged, the wale and course-wise curling distance of fabrics, especially the course-wise curling, decrease with increasing underlap of the second guide bar; However, the wale and course-wise curling distance of fabrics increase with increasing underlap of the first guide bar when the structure of the second guide bar remains unchanged.
Key words: polyester, warp-knitted fabric, curling, structure, draw off density
