Abstract:

In order to obtain a new denim fabric with advantages of both knitted denim fabric and woven denim fabric, the development of fake knitted denim fabric was discussed  from the aspects of yarn selection, weaving and finishing , and the relevant mechanical indexes of fake knitted denim fabric, knitted denim fabric and cotton woven denim fabric were compared. Furthermore, the Kawabata evaluation system was employed to synthetically analyse mechanical properties including tensile, shear, bending, compression and friction of these fabrics. The results show that the fake knitted denim fabric which uses pure cotton combed yarn and polyester filament spandex core spun yarn as warp and weft yarn, with composite right-hand twill weave, has warp tensile strength of 685 N and tear strength of 59 N after special finishing. The fake knitted denim fabricowercomes the disadvantages of both weaving denim fabric and knitted denim fabric. The fabric is stiff, smooth and soft, and also has elasticity and shape-retention in handle.

Key words: fake knitted denim, fabric weave, mechanical property, fabric style evaluation index
