A knitting machine for manufacturing plush fabrics includes latch-less cylinder needles (11) in a cylinder (10), latch needles (21) located on a needle dial (20) and a cutting unit (30). The loop (41) formed by a plush thread (40) can be directly knitted in a fabric formed by ground threads (50) to form a longer plush on the fabric surface. By changing the dimension of the needle dial (20), the interval of the peripheral edge of the needle dial (20) and the cylinder needle (11) can be increased so that the plush thread (40) held on the hook (112) of the cylinder needle (11) can be stretched by the latch needle (21) to become a longer loop. Finally, the loop (41) is severed by the cutting unit (30) to form a plush fabric of a longer plush.
