  The tulle lace knitted fabric disclosed in Patent Documents 1 and 2 is patterned with a predetermined embroidery thread or pattern thread, and finished into a fabric having a desired thickness. However, in general, apparel and other fabric products are produced by forecasting demand. In particular, fabrics are separated by producers in each process, and knitted fabrics by upstream manufacturers in the production process are It is necessary to predict the production volume and produce some extra. The production machine, which is the most upstream product in knitting production, becomes a major problem in downstream product production if it becomes a shortage, so there is no choice but to produce excess production, resulting in excess inventory and changes in the product cycle. In many cases, there was a lot of unsold sales. Unsold machines were sold at a low price or had to be discarded and disposed of, which was a waste of labor and resources.

  The present invention has been made in view of the above-described background art, and can flexibly set the application of the raw machine to be manufactured, eliminate unsold products, eliminate waste of resources, and enable stable production regardless of the season. It aims at providing the manufacturing method of a knitted fabric.

  The present invention is a method of manufacturing a knitted fabric having a basic structure formed over the entire width and a handle structure applied to a predetermined position of the basic structure, and the thickness of the knitting yarn of the basic structure On the other hand, the thickness of the knitting yarn of the pattern structure is 2 to 6 times, and the average number of the knitting yarn of the pattern structure in the entire width of the knitting machine is the average number of the knitting yarn of the basic structure. When the raw machine is knitted by setting it to 24% to 55% and dyes the live machine, the width in the wale direction of the live machine is set to a desired fabric thickness by shrinkage during dyeing. The knitted fabric is manufactured from the same raw machine to the desired fabric thickness according to the setting from thin fabric to thick fabric.

  The knitting yarn forming the basic structure is a knitting yarn made of synthetic resin fibers. Further, the knitting yarn forming the pattern structure may be a knitting yarn of short fibers.

  When dyeing the raw machine, the width in the wale direction of the raw machine is set to a predetermined value, and the shrinkage at the time of dyeing is adjusted to selectively produce the fabric of lace-like fabric or winter ground thickness To do.

  According to the method for producing a knitted fabric of the present invention, it is possible to form a lace fabric having a lot of space in the stitches or a winter fabric having a thick cloth with one kind of raw machine, and use the raw machine without waste. Can do. As a result, it is possible to produce knitted fabrics stably throughout the year without excessive inventory and shortage.

It is a schematic diagram which shows the knitting structure of the raw machine of one Embodiment of this invention. It is a flow explaining the manufacturing process of the knitted fabric of this embodiment.

  Hereinafter, a method for manufacturing a knitted fabric according to an embodiment of the present invention will be described with reference to the drawings. A knitted fabric 10 according to an embodiment of the present invention is a lace fabric in which a pattern structure 14 is applied to a tulle structure 12 which is a basic structure, as shown in FIG. The tulle structure 12 has a space 12a that is a stitch formed in a turtle-shaped structure and arranged regularly. The handle structure 14 provided in the tulle structure 12 is knitted in addition to the tulle structure 12 by knitting yarn and by a predetermined fold.

  The knitting yarn constituting the knitted fabric 10 is 2 to 6 times, preferably 4 to 5 times thicker than the knitting yarn of the tulle structure 12. Is set. For example, when the thickness of the knitting yarn of the tulle structure 12 is 30 denier, the knitting yarn of the pattern structure 14 is set to 60 denier to 180 denier. If the knitting yarn of the pattern structure 14 is thinner than this, the fabric thickness when the knitted fabric is formed by contraction will not be sufficiently thick, and if the thickness of the knitting yarn is larger than the above value, the lace tone for summer This is because there is a problem that it is not suitable for the dough.

  Furthermore, the average number of knitting yarns of the pattern structure 14 in the entire width of the knitting machine to be knitted is set to 24% to 55%, preferably 30% to 45% of the average number of knitting yarns of the tulle structure 12. If the average number of knitting yarns of the pattern structure 14 is less than this, the fabric thickness when the knitted fabric is formed by contraction will not be sufficiently thick, and if the average number of knitting yarns of the pattern structure 14 is more than this, sufficient space will be obtained. Is not suitable for summer lace fabrics. For example, when the number of knitting yarns of the tulle structure 12 per inch is 28, the pattern is set so that the number of knitting yarns of the pattern structure 14 is 7 to 15.

  The type of knitting yarn of the knitted fabric 10 is a monofilament yarn of synthetic fiber such as polyester or nylon, and the yarn of the tulle structure 12 can be used for both elastic yarn and non-elastic yarn, but elastic yarn is preferred. The yarn of the knitting yarn of the handle structure 14 may be a monofilament yarn of synthetic fiber or a knitting yarn of short fibers of wool or cotton.

  In the manufacture of the knitted fabric 10 of this embodiment, as shown in the flow of FIG. 2, first, a knitting machine is used to knitting the tulle tissue 12 and the handle tissue 14 with a predetermined number of folds (s1). Here, we will produce the raw machinery needed throughout the year, regardless of the season. Then, the knitted raw machine is sent to a dyeing process according to needs, and dyed at a predetermined temperature and expansion / contraction rate. At this time, a predetermined shrinkage ratio from the raw machine to the fabric is set according to the season and application (s2). For example, when manufacturing the lace-like knitted fabric 10 shown in FIG. 1 as a fabric for summer, the shrinkage ratio of the width in the wale direction from the state of the raw machine is a minimum value, for example, the width in the wale direction is 5%. Set to contracted state. Conversely, when manufacturing a thick fabric for winter, the shrinkage rate is set to about 30%. The dyeing temperature is about 30 minutes at 130 ° C. when the yarn of the tulle structure 12 is polyester, and about 60 minutes at 80 ° C. to 95 ° C. when nylon is used. When no force is applied during dyeing at this temperature, the living machine shrinks by about 30%, but in this embodiment, the wale is reduced so that the amount of shrinkage during dyeing becomes the predetermined value initially set as described above. The direction width is set and dyed (s3). Therefore, in the case of making a fabric for winter, dyeing is performed by leaving it to shrinkage by heating. As a result, a thick winter dough is produced (s3). Thereafter, the fabric is dried with the width of the fabric, and a fabric which is a knitted fabric having a desired use and thickness is finished (s4).

  In the knitted fabric 10 of this embodiment, the thickness of the knitting yarn of the pattern structure 14 is set to 2 to 6 times, preferably 4 to 5 times the thickness of the knitting yarn of the tulle structure 12 during knitting. In addition, the average number of knitting yarns of the handle structure 14 in the whole width in the wale direction of the knitting machine is 24% to 55%, preferably 30% to 45% of the average number of knitting yarns of the tulle structure 12. Set to% and organize. By knitting the raw machine under these conditions, it is possible to obtain a knitted fabric having a desired desired fabric thickness in the dyeing process from the state of the thin cloth of the raw machine immediately after knitting. When the fabric thickness, which is a knitted fabric, is transferred to the dyeing process, the dyeing process is performed by fixing the width for fixing the raw machine at the time of dyeing to a predetermined value and setting the desired shrinkage rate. Thereby, when forming a knitted fabric from a living machine, it is possible to form a fabric that is a knitted fabric of a desired use with a desired thickness from a thin lace-like knitted fabric to a thick winter knitted fabric.

  According to the manufacturing method of the knitted fabric 10 of this embodiment, a raw machine having a predetermined condition is knitted, and in the subsequent dyeing process, the shrinkage ratio of the raw machine is set to a value as necessary, and a desired stitch is obtained. A knitted fabric of a size or fabric thickness can be formed. As a result, it is only necessary to organize one type of raw machine, and it is possible to manufacture the raw machine stably regardless of the season, eliminate the shortage and excessive production of the raw machine, and always keep the appropriate production amount and without missing parts. It becomes possible to supply.

  The knitted fabric of the present invention is not limited to the above embodiment, and the basic structure may be a 4-course tulle structure other than the 6-course tulle structure shown in FIG. Any structure may be used as long as it has a space, and the pattern structure can be knitted into the basic structure.
