A yarn cutter for a shuttleless loom, particularly for a water jet loom, comprising a pair of knife bodies each having a cutting edge formed of a ceramic and being driven for relative sliding motion in mutual contact.

Yarn cutter for shuttleless loom

A woven fabric formed by utilizing an interlaced false twisted yarn as the warp and the process for producing such woven fabric. The interlaced yarn as the warp has such a particular configuration that the collectness of the yarn can be effectively maintained during the weaving operation and, therefore, pilling of the individual filaments and snagging can be effectively prevented, and the sizing of the warp can be omitted. Since the interlaced yarn of the invention is effective bulkiness even if the superior collectness is provided, any possible slip of yarns from the crossing point between the warp and the weft can be effectively prevented. Consequently, fabric having a low yarn density can be easily produced. When the above-mentioned fabric is woven, the warp is wet at a weaving zone between the healds and cloth-fell defined by the beating motion of the reed. Accordingly, a water jet loom is preferably utilized to produce the woven fabric of the present invention. For eliminating the problem of jet soil, preferable treating agents which are selectively applied to the multifilament yarn for producing the interlaced yarn of the present invention are disclosed.

Woven fabric utilizing a particular textured yarn and method for

A textured polyester yarn having improved variation in dyeability along its length is composed of a plurality of individual filaments each having thick and thin sections randomly distributed along the filament axis, said yarn having an Uster evenness value of 1.0 to 10.0%, a T index of 3 to 30 and a variation in reflected light intensity in a continuous dyeing test of .+-.0.15 to .+-.0.80 and said yarn preferably having not-untwisted portions containing genuine twists of a fixed direction intermittently retained at random along its length. The yarn is produced by false twisting a polyester yarn composed of a plurality of individual filaments each having variation in cross-sectional area along its length, in which the thick sections have a birefringence of 15 to 80.times.10.sup.-3 and the thin sections have a birefringence of 90 to 200+10.sup.-3, at a temperature of not lower than 180.degree. C and under a twisting tension of 0.05 to 0.8 g/d with a variation with respect to the average twisting tension of .+-.5 to .+-.20%.
