ABSTRACT:
TECHNICAL FIELD
The present invention relates to a method of knitting knitwear whose sleeves and body are joined by using a flat knitting machine.
BACKGROUND ART
The knitting method of joining together knitted fabrics knitted in different regions on the flat knitting machine in the course of the knitting process can eliminate or simplify the tail end sewing process. The application of this knitting method to the knitting of sweater and the like enables the knitting of knitwear which is called a non-sewing knitted fabric.
When sweater is knitted in the form of the non-sewing knitted fabric, the front and back bodies are knitted into a tubular body continuously joined at each end thereof. In parallel with this, the right and left sleeves situated at each side of the body are each knitted into a tubular form and shifted to the body side, so that the sleeves and the body are overlapped and joined together in a joining region extending from the underarm to the shoulder.
The sleeves and the body are joined together to have a proper angle &thgr; formed by the sleeve and the body joined together (hereinafter it is referred to as “the sleeve attaching angle”). This sleeve attaching angle &thgr; can be adjusted by changing a course number ratio between the sleeve and the body after the start of knitting of joining together the sleeve and the body. With reference to
FIGS. 12A and 12B
, the knitting method of adjusting the sleeve attaching angle &thgr; will be described.
FIG. 12A
shows the knitting sequence for the process of joining together the sleeves and the body.

In the knitting method of
FIG. 12
, a single yarn feeder is used for knitting both of the front fabric and the back fabric. In the course

and the left front sleeve

is repeated five times. In the course

, so that the sleeves and the front body are joined together. Then, the knitting goes on to the knitting of the back fabric. In the course

and the back body
103
b
are continuously knitted, the right back sleeve

and the left back sleeve

are shifted to the body, respectively, to be joined to the back body. Sequentially, in the courses

127
, the knitting that whenever the back fabric is knitted in one course, the right back sleeve
105
b
and the left back sleeve
107
b
are shifted to and joined to the back body
103
b
is repeated five times. In the course
129
, after the back body

b
and the right back sleeve
105
b
are continuously knitted, the right back sleeve
105
b
and the left back sleeve
107
b
are shifted to the body, so that the sleeves and the back body are joined together. The sleeve attaching angle &thgr; varies depending on the course number ratio of the sleeve to the body after the start of the joining knit to join together the sleeve and the body. As the course number ratio of the body to the sleeve is increased, the sleeve attaching angle &thgr; increases and comes nearer to a right angle. On the other hand, as the course number ratio of the body is reduced, the sleeve attaching angle &thgr; reduces and comes nearer to a parallel with the body.
In the knitting method mentioned above, in the courses

and

, the knitting of the sleeves

is suspended and the knitting to join either of the front and back bodies and the sleeves is continuously performed. During this course knitting, only either of the front knitted fabric and the back knitted fabric is reduced in knitting width. When this knitting wherein the knitting of the sleeves is suspended and the joining knit to continuously join the sleeves and the body of either of the front knitted fabric and the back knitted fabric is repeated five consecutive times, as shown in
FIG. 12
, the stitches on the edge of the front knitted fabric and the stitches on the edge of the back knitted fabric will be moved away from each other by five stitches. This may cause the problems of causing yarn rupture in the yarn extending between the stitch on the edge of the front knitted fabric and the stitch on the edge of the back knitted fabric, thus interrupting the knitting operation and of generating in the knitwear an undesirable knitted line to significantly spoil the commercial value of the product. If the sleeves are not knitted but are shifted to and joined to the body repeatedly, in order to bring the sleeve attaching angle &thgr; closer to right angle, then the same stitch will be transferred over and over again by the time the knitting of the sleeves suspended is restarted. As a result of this, the stitch laid over the stitch of the body is strung out. This may cause an undesirable hole in the joining line

along which the sleeves and the body are joined together, to give a dirty-looking to the joining line, or may cause yarn breakage.
Meanwhile, the applicant discloses in JP Laid-open (Unexamined) Patent Publication No. A-2000-256947 the knitting method using an elastic yarn for joining together the sleeves and the body. This knitting method comprises the step that while the sleeves and the body are both knitted, the sleeves are shifted to the body and joined to it; the step that the knitting of the body is suspended, during which the knitting of sleeve caps of the sleeves is continued in a flechage knitting, and then the last course of the sleeves is knitted by using the elastic yarn; and the step that the knitting of the body is restarted, so that the sleeves and the body are joined together along the sleeve caps by transferring stitches whenever a predetermined number of courses of the body are knitted. After these steps, the sleeves and the body are joined together. In this knitting method, since the sleeve caps are knitted into a desired shape in the flechage knitting and since after completion of this flechage knitting, the sleeves are joined to the body along their sleeve caps without knitting the sleeve caps, the shape of the sleeves and the sleeve attaching angle can both be freely set. In addition, since the last course of the sleeves is formed by using the elastic yarn, even when the same stitch is transferred sequentially, there is little fear of causing yarn breakage or stringing out the stitches.
It is the object of the present invention to disclose a knitwear knitting method comprising the step that tubular sleeves are knitted at each side of a tubular body; and the step that the sleeves are shifted to and joined to the body in a joining region in which the sleeves and the body are to be joined together, wherein the knitwear having a good-looking joining line along which the sleeves and the body are joined together can be knitted at any selective sleeve attaching angle. It is another object of the present invention to disclose a knitting method of knitting knitwear that requires no special yarn, such as an elastic yarn, for joining together the sleeves and the body at a large sleeve attaching angle close to right angle.
