The invention discloses a free cut fabric not prone to hemming. The free cut fabric comprises a fabric body, the fabric body comprises multiple pieces of first yarn and multiple pieces of second yarnwhich are mutually intertwined, each piece of first yarn is laid every one stitch in turn to form loops, so that a warp-knitted structure formed by the first yarn is a velvet structure, the underlap of the velvet structure is across two stitch lengths, and the velvet structure serves as a surface structure; each piece of second yarn is laid on two adjacent knitting needles and knitted into loops,so that a warp-knitted structure knitted by the second yarn is a warp-ribweave structure, and the warp-ribweave structure serves as a ground structure. The surface structure and the ground structure are combined to form the fabric body. The fabric formed by combining the two structures is high in elasticity, the loops are mutually locked, and the loops are not likely to run, the stress of the loops on the bottom face is balanced, and hemming of the fabric can be prevented. According to the fabric, the phenomena of hemming and running in the cutting process can be effectively avoided, the fabric is convenient to use, no folds can be generated when the fabric is put on the body of a wearer, and the using comfort is high.

The invention provides a knitting method of a multi-bar warp-knitting machine. The method includes the following steps of firstly, preparing a raw material wire; secondly, feeding the raw material wire into a looping ground bar; thirdly, making the looping ground bar start knitting, wherein the raw material wire is composed of N yarns, N is larger than or equal to 1, and at least one of the N yarns is a raveling-resistant yarn. Raveling-resistant yarn loops are added on the basis of existing loops, the tightness of the existing loops is increased, joints of all the loops are staggered or overlapped, ground net yarn loops are made to have quite strong cohesive force and more closely cohered to fancy yarns forming a pattern, and even no chain stitch transfer transverse yarn or thermofuse yarn is added, the ground yarn loops and the fancy yarns are not prone to raveling after damage.
