Description

Structural improvement of elastic knitted fabric weft

The present invention is a knitted fabric, and particularly refers to a woven fabric having a secondary yarn on a weft knitted fabric.

The knitted fabric is a fabric formed by bending a yarn into a loop by a knitting needle and slicing each other, and can be divided into a weft knitted fabric and a warp knitted fabric. Among them, the weft knitted fabric refers to a knitted fabric knitted from the transverse direction. That is, the weft knitting machine makes the yarn reciprocating or circularly moving from one side of the machine to the other side, and a new knitting stitch can be formed by the movement of the knitting needle. The yarn of the weft knitted fabric is formed by weaving a knitting needle in a weft direction in a row and a row of stitches which are connected to each other. Among them, all the coils of each course are woven from one yarn.

The conventional weft knitted fabrics are made by bending a plurality of transverse weft yarns into a plurality of loops and interlacing with the loops of adjacent weft yarns, so that the density is not high, when the weft knitted fabric is worn. When the user is on the body, the curve of the curvature of the human body is inconsistent. Because the gap between the weft yarns is enlarged after the tension is stretched, the visual penetration is easy to occur, which is inconvenient for the user.

In view of this, the inventors have conceived and further studied, and finally invented a structural improvement of an elastic knitted fabric weft.

The invention provides a structural improvement of an elastic knitted fabric weft yarn, and the main purpose thereof is to increase the density of the knitted fabric, so that the knitted fabric is less likely to have visual penetration when subjected to external force stretching.

In order to achieve the above object, the present invention provides a structural improvement of an elastic knitted fabric weft yarn, comprising: a weft-knitted knitted fabric, which is composed of a plurality of weft yarns, each of which is bent into a plurality of loops, and the loop of adjacent weft yarns The loops are sleeved with each other such that the two sides of each loop have two contact portions between the loops of the adjacent weft yarns; and at least one pair of yarns are threaded and interwoven in each of the weft yarns, at least one side of the weft yarns The at least one sub-yarn is formed in the contact portion, and each of the arc portions is located in the ring, and the Young's coefficient of the sub-yarn is lower than the Young's modulus of each of the weft yarns.

In order to achieve the above object, the present invention provides a structural improvement of another elastic knitted fabric weft yarn, comprising: a weft-knitted knitted fabric, which is composed of a plurality of weft yarns, each of which is bent into a plurality of loops, and adjacent weft yarns. The loops are sleeved with each other such that each of the two sides of the loop has a first contact portion and a second contact portion between the loops of the adjacent weft yarns; and at least one pair of yarns are pierced and interwoven In the weft yarn, in the first contact portion on one side of at least one of the weft yarns, the at least one sub-yarn is formed into a plurality of arc portions, each of the arc portions is located across the second loop, and the Young's coefficient of the sub-yarn is lower than each of the weft yarns. Young's coefficient.

The invention utilizes the structural improvement of the provided elastic knitted fabric weft yarn, and the obtained effect is: by at least one weft yarn of the weft knitted fabric An interlaced yarn is interposed in one of the contact portions, and a Young's modulus of the sub-yarn is lower than a Young's modulus of the weft yarn, thereby reinforcing the tensile strength of the weft knitted fabric in the weft direction through the sub-yarn In order to avoid visual penetration of the knitted fabric when it is stretched by external force.

The present invention has been described in connection with the preferred embodiments of the present invention in accordance with the accompanying drawings.
