Description

  The present invention relates to a jacquard knit fabric and a knitting method thereof.

  Conventionally, in order to raise a jacquard knit knitted fabric, a yarn having good raising properties is used. In order to obtain a raised product having a volume, strong raising is required, but there is a problem in that the loop constituting the knitted fabric is broken by raising. In order to avoid this, measures have been taken to use special yarns with good napping properties and to increase the loop in the knitting process in order to facilitate napping.

  In general, raised products of jacquard knit fabric are lightly raised so that the loop yarn is not cut off during the raising process and the loop shape is not affected. It is a knitted fabric of a degree. The jacquard knit raised products obtained in this way are mainly fall / winter clothes using acrylic yarns and wool yarns with good brushing properties, and are not considered much for other uses.

Further, Patent Document 1 discloses a thin brushed fabric that forms a pattern and / or a pattern between a raised portion and a non-raised portion by fibrillation by using two or more kinds of fibers having different fibrillation easiness. Are known. [0012] to [0013] of this document describes that the present invention can be used for a jacquard pattern using a jacquard knitting machine, but there is no knitting method or knitting organization chart for that purpose. Not disclosed.

  An object of the present invention is to provide a knitting method of a jacquard knit knitted fabric that enables strong raising processing without using a special yarn having good raising properties, and a knitted fabric obtained thereby.

  The present invention is a jacquard knit knitting method, in which a yarn (ground yarn) constituting a jacquard structure and a yarn for raising (brush yarn) are knitted with the same feeder, thereby forming a knitted loop of the raised yarn, The ground yarn loop is covered to make a jacquard knit fabric suitable for raising. The present invention is also a knitted fabric obtained by this method.

  The jacquard knit knitted fabric obtained by this knitting method does not affect the loop of the ground yarn constituting the jacquard knit knitted fabric even if raising is performed because the raised yarn appears greatly on the knitted fabric surface. Strong brushed processing becomes possible. As a result, a fine suede-like jacquard knit fabric can be obtained by raising.

  The raised knitted fabric thus obtained can be used for industrial materials such as automobile seat materials, interior materials, chairs and sofas.

  FIG. 1 is an operation diagram of a dial needle and a cylinder needle in the present invention. 2 (1) to (6) are knitting cross-sectional views taken along the portions (1) to (6) in FIG.

  The cylinder needle 10 and dial needle 20 selected by the knit cam or other needle selection means (not shown) move to the knit position, and the old loops 13 and 23 are disengaged from the latch (FIG. 2- (1)). Thereafter, the cylinder needle 10 is lowered, and the dial needle 20 starts to move inward in the knitting machine (FIG. 2- (2)). At this time, the ground yarn 32 fed from the vertical hole 31 of the yarn carrier 30 is captured by the dial needle hook 21, and the dial needle latch 22 is closed by the old loop 23 (FIG. 2- (3)). The dial needle 20 with the latch closed moves in the lateral direction while maintaining the state (FIG. 2- (4)).

  On the other hand, the raised yarn 34 fed from the lateral hole 33 of the yarn carrier 30 is captured by the cylinder needle 10. At this time, the cylinder needle 10 also captures the ground yarn 32 in the dial needle hook 21 at the same time and the cylinder needle by the old loop. The latch 12 is closed (FIG. 2- (4)). Further, when the cylinder needle 10 is lowered, the raised yarn 34 is drawn over the dial needle 20 with the latch closed, and the cylinder old loop is knocked over while pulling two yarns together with the ground yarn (FIG. 2- ( 5)). Then, the raised yarn straddling the dial needle latch is detached from the dial needle latch by the dial loop knock-over, and forms a half-moon shaped loop (FIG. 2- (6)).

  With this knitting method, the length of the raised yarn to be fed is increased, and the length is almost the same as that of the double-sided knitted ground yarn although it is cylinder knitting. As a result, the loop of the raised yarn is formed in a state where the loop of the ground yarn is covered in the form of a plating, and appears to rise greatly on the surface of the knitted fabric. When this knitted fabric is raised, a jacquard knit raised knitted fabric is obtained.

  Further, in a knitting machine that repeats a pattern with at least two feeders, the first feeder feeds the first color ground yarn and the raised yarn, and the second feeder feeds the second color ground yarn and the raised yarn. When knitted, a two-color jacquard knit fabric suitable for raising can be obtained. When this knitted fabric is brushed, a two-color jacquard knitted fabric is obtained.

  Furthermore, in a knitting machine that repeats a pattern with at least two feeders, if one of the first feeder and the second feeder feeds ground yarn and raised yarn, and the other feeder knits with only ground yarn. An uneven jacquard knit fabric suitable for raising. When this knitted fabric is raised, a raised knitted fabric of jacquard knit with unevenness can be obtained.

  As a method of raising, conventionally known methods, for example, raising with a cloth or sandpaper can be arbitrarily employed.
