Description

Sawtooth-free longitudinal curve line braiding process, fabric and vamp

Technical Field

The utility model relates to a sawtooth-free longitudinal curve line knitting process, fabric and vamp, and belongs to the technical field of spinning.

Background

If one line in the transverse direction is not in the same knitting line in the knitting process of the knitted vamp; or a longitudinal line is not in the same weave column, then the line has 'saw teeth', and the bigger the coil is, the more obvious the 'saw teeth'. The saw teeth can affect the smoothness and the aesthetic property of the lines and cannot be avoided theoretically. In order to improve this problem, there is then a generation of the present solution.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model provides a sawtooth-free longitudinal curve line knitting process, a fabric and a vamp, which adopt the following technical scheme:

as a first aspect of the present utility model, there is provided a process for knitting a zigzag-free lengthwise curved line, comprising:

step A, basic knitting: performing full-face knitting;

step B, stitch knitting: stitch-over knitting of the back/front needle bed loops of the corresponding knitting row to the front/back needle bed;

step C, loop transferring knitting: moving the loops of the back/front needle bed rightward/leftward by N needle positions, and turning over the needles to the front/back needle bed for loop transferring knitting, wherein N is a positive integer;

step D, repeatedly knitting: repeating the basic knitting of the step A, the stitch turning knitting of the step B and the stitch transferring knitting of the step C, and at least one needle bed moving direction of the adjacent stitch transferring knitting is opposite;

step E, weaving: and (5) repeating the basic knitting of the step A.

Further, the step B stitch-bonding and the step C loop-bonding are performed simultaneously for all yarns on the corresponding fabric.

Further, the knitting mode of the step A basic knitting also comprises hanging mesh knitting, hollow needle knitting and four-plane knitting.

Further, the step C is loop-transferring knitting: the back/front needle bed stitch moves to the right/left by 1 needle position, and then turns over the needle to the front/back needle bed for transferring knitting.

Further, the number of stitches and the number of needle positions of the loop-moving knitting movement are not limited.

As a second aspect of the present utility model, a fabric is proposed, which uses the zigzag-free longitudinal curved-line knitting process as described above, comprising a fabric body, which is of at least one layer of knitting structure.

Further, the fabric body is woven by high-elastic yarns and TPU, and the high-elastic yarns comprise any one of terylene, chinlon and acrylon.

Further, the degree of bending of the threads of the fabric body is determined by the number of needles of the transfer knitting.

Further, the fabric body is knitted in a manner including stitch-turning knitting, loop-transferring knitting, empty-needle knitting, hanging-mesh knitting and quad-flat knitting.

As a third aspect of the utility model, an upper is proposed, at least a portion of which comprises a non-serrated longitudinal curvilinear knit fabric as described above.

Compared with the prior art, the utility model has the following beneficial effects:

1. the longitudinal lines on the vamp are curved, and if the conventional jacquard is used for bending lines, saw teeth are generated, so that the lines and the beautiful appearance of the vamp are affected. The scheme uses a loop-transferring knitting method, and a longitudinal straight line is moved out of a certain radian by moving a plurality of needle positions leftwards and rightwards to become a smooth curve line without saw teeth. The curve lines woven by the scheme are smooth, and the texture of the fabric is greatly improved.

The utility model creates a knitting process without sawtooth longitudinal curve lines, which can effectively solve the sawtooth flaws of the longitudinal curve lines of the fabric and further perfect the diversity of the flying knitting texture. Meanwhile, the novel creative will also provide new design ideas and development directions for the design and manufacture of other novel vamps.
