Description

  The present invention relates to a pile knitting method for producing a ring-shaped loop on a knitted ground. More specifically, the present invention relates to a horizontal knitting machine in which a pile loop can be knitted without adding a member dedicated to pile knitting to a flat knitting machine. The present invention relates to a pile knitting method using a knitting machine.

  The flat knitting machine is a flat knitting machine that mainly knits knit clothing such as a sweater, and is a knitting machine capable of forming knitting and various changes in structure. In recent years, computer control has progressed, and integrated knitting with an attached portion and integral knitting that eliminates the need for knitting by continuously knitting each part are also progressing.

  Mechanically, V-bed machines with two needle beds (needle beds) facing each other across the mouth are arranged in an inverted V shape and the needles come out of the ribs are the mainstream. Used to knit the weft knitted by moving the carriage with cam.

  The flat knitting machine includes a single knitting machine and a double knitting machine depending on the configuration of the needle bed, and various knitted fabrics are knitted by these knitting machines. The single knitting machine is a needle bed in which a large number of knitting needles are arranged in a row, and the double knitting machine is a needle bed in which a large number of knitting needles are combined in two rows.

  The basic organization of the knitted fabric of the flat knitting machine is generally a flat knitting called Tenjitsu knitting that is knitted by a single knitting machine. In the double knitting machine, rib knitting that extends in the width direction of the knitted fabric than the flat knitting, and elasticity Highly knitted fabrics such as double-sided knitting are obtained, and are used in a wide variety of products depending on the characteristics of each knitted fabric.

  By the way, in the knitted fabric, there is a pile knitting in which a ring-shaped loop is provided on the knitted ground. Pile knitting is also called “Wana” in Japanese. As shown in FIG. 4, the knitting method is a knitting method in which a loop is fastened with a stop yarn and knitted by attaching a pile yarn PY to a stop yarn (ground yarn) RY. The loop of the pile yarn PY is expanded using a dedicated member, and the pile loop P is knitted.

  In this case, flat knitting and rubber knitting are applied, but in finishing, there are cases where the pile loop is left as it is, and there are cases where the pile loop is cut and feathered. Pile knitting is thick and has high heat retention. Characteristic is soft.

  A flat knitting machine is basically a machine that forms a knitted fabric by forming loops in yarns in the width direction of the knitted fabric and sequentially connecting these loops. For this reason, when performing pile knitting in which a ring-shaped loop is formed on the surface of the knitted fabric, it is necessary to provide a member dedicated to the pile (Patent Documents 1 to 3).

  For example, in Patent Document 1 below, an auxiliary needle bed with a pile pull-out needle is provided above one needle bed, and the pile thread is locked to the pile pull-out needle of the auxiliary needle bed, and then it is wiped off. This makes it possible to organize pile loops.

  In the following Patent Document 2, a slider member for pile knitting is attached to the needle groove of the opposing needle bed instead of the knitting needle, and at the time of pile knitting, the slider member is advanced to the tooth mouth and pile yarn is passed over. Thereafter, the pile yarn is cut by a cutting member formed on the rim of the slider to form a cut pile.

  In Patent Document 3 below, the knitting needle provided in the needle bed includes two elastic plates that slidably hold the hook of the needle body, and a slider needle that can open and close the hook by the tongue of the elastic plate; The pile loop is knitted by the operation of this compound needle.

  However, the pile knitting technique disclosed in Patent Document 1 requires an auxiliary needle bed for mounting a member dedicated to pile knitting, which not only complicates the knitting machine but also increases the cost. There is a problem of end.

  In the pile knitting technique disclosed in Patent Document 2, it is necessary to mount the slider member in the needle groove of the needle bed instead of the knitting needle, and it is possible to select either normal knitting or pile knitting for knitting. However, there is a problem that both cannot be performed simultaneously.

  Of the above Patent Documents 1 to 3, the pile knitting technique disclosed in Patent Document 3 only requires a compound needle as a knitting needle arranged in parallel with the needle bed. This is also advantageous in terms of cost. Further, unlike the above-mentioned Patent Document 2, pile knitting can be performed on a part of the knitted fabric without changing the knitting needles.

  However, in the pile knitting technique disclosed in Patent Document 3, as a premise for performing the pile knitting, the old stitch that is locked to the hook of the needle body is held on the slider, and thereby the thread that is emptied is tightened. (Fastening yarn) is supplied to form a joint stitch.

  Therefore, the joint stitch merely exhibits a loop shape and is not yet fixed, and composite stitches having no loop shape fixed are continuously arranged in the knitting width direction, and the joint stitch is not held well. Then, it is difficult to perform the subsequent pile knitting.

  In particular, the pile loop is formed so as to protrude from the knitted fabric, and in order for the knitted fabric not to lose its shape, it is necessary to reliably stop the pile loop with a joint stitch (stopping thread).

  Therefore, when performing pile / loop knitting, additional hardware such as a loop presser or sinker that presses the knitting yarn down between the composite needles must be used, resulting in a high cost. There was a problem.

  The present invention has been made in view of the above problems, and when performing pile knitting with a flat knitting machine, a pile knitted fabric can be knitted with an existing flat knitting machine without adding a special member dedicated to pile knitting. It is to provide a pile knitting method.

In order to solve the above-mentioned problem, the first invention includes a pair of front and rear needle beds opposed to each other with a tooth opening interposed therebetween, and a yarn supply carrier for supplying a yarn to the pair of front and rear needle beds, and the rear needle A plurality of knitting needles B1, B2, B3,... Of the bed are rib-type flat knitting machines that are movable at a predetermined pitch with respect to the plurality of knitting needles F1, F2, F3,.

A plurality of knitting needles F1, F2, F3,..., And a plurality of knitting needles B1, B2, B3,.
After the total needle rubberizing step, the rear needle bed is moved to the right by one pitch so that the knitting needle B1 of the rear needle bed is located between the knitting needles F2 to F3 of the front needle bed, and the front needle bed , A plurality of knitting needles F1, F2, F3,... And a plurality of knitting needles B1, B2, B3,. Knitting process,
After the tentacle knitting process, the rear needle bed is 1.5 mm so that the knitting needles B1, B2, B3,... Of the rear needle bed face the knitting needles F1, F3, F5,. .. Are moved to the left side of the pitch, and among the plurality of knitting needles B 1, B 2, B 3,... A transfer process of transferring to every other knitting needle of F3, F5,.
After the transfer step, the rear needle bed is moved to the right by a predetermined pitch with respect to the front needle bed and left on every other knitting needle of the knitting needles B1, B2, B3,. It consists of a step of removing all the yarn from every other knitting needle,
A stop yarn is formed by the total needle rubber step and the tentacle knitting step, and a pile loop is formed by the transfer step and the peeling step to form a pile knitted fabric on the knitted ground.

  In the removing step, the rear needle bed is preferably moved to the right by 1 to 2 pitches with respect to the front needle bed.

  In the transfer step, the knitting needle used for transferring from every other knitting needle of the rear needle bed to every other knitting needle of the front needle bed is the knitting needle B (2n-1; Integer), and the knitting needle F (2n-1; n is an integer) in the front needle bed.

  In the transfer step, the knitting needle used for transferring from every other knitting needle of the rear needle bed to every other knitting needle of the front needle bed is the knitting needle B (n + 1; Integer), the front needle bed may be the knitting needle F (n + 1; n is an integer).

  According to the present invention, a pile loop is applied to a knitted fabric by sequentially performing a knitting process of a total needle rubber process, a tentacle knitting process, a transfer process, and a peeling process by the operation of a pair of front and back needle beds in an existing flat knitting machine. Therefore, a dedicated member for knitting a conventional pile knitted fabric can be eliminated, and the pile knitted fabric can be knitted at low cost.

  In addition, it is only necessary to incorporate a pile knitting process such as a total knitting rubber process, a tentacle knitting process, a transfer process, and a peeling process into a part of the knitted fabric knitting process of an existing flat knitting machine without using a dedicated member. It is possible to knit a molded product having a wide variety of designs combined with other knitted fabric patterns.

  Furthermore, in the peeling process, the rear needle bed is moved to the right by a predetermined pitch with respect to the front needle bed, and then the pile loop is knitted by removing the thread and then the air is wrapped in the knitted pile loop. Therefore, the loop is swelled, and a pile fabric with a soft touch can be obtained.
