Description
Technical field
The present invention relates to the decision of the coil number of knit product, is that the coil number of knitting width or pin number and length direction is the technology that the row number also can be produced roughly the same with target size knit product in particular to the coil number of decision width.
Background technology
The applicant once proposed to weave the sample littler than the knit product of reality, was the feel sample, thus the scheme (patent documentation 1:JP2676182) of the plane No. of decision knit product.In this specification, plane No. means the unit width of knit product or the coil quantity of length, and unit for example is (coil/cm) etc.In the patent documentation 1, change the braiding condition, weave a plurality of feel samples, and select the sample of optimum feel.Wherein knitting width is certain.Then, measure the unit width of selected sample or the coil number of length, the plane No. of decision knitted fabric.Owing to confirmed plane No. and specified width and length, therefore confirmed the pin number through the plane No. that width multiply by width according to the pattern data of target knit product.Confirm the row number through the plane No. that length multiply by length direction in addition.Thus, while can reduce the man-hour of revising plane No. in kind of producing knit product.
But the inventor finds that only the method through patent documentation 1 not necessarily can determine optimum plane No..If can not find optimum plane No., then knit product can not form the size of regulation, in the stage at the braiding stock, need increase and decrease corrections such as row number for weave data.Particularly under the situation such as sweater that cylindrical fabric are bonded with each other through seamless knitted; Because while braided sleeve and the different garment piece of the such aspect ratio of body sheet; Therefore become knitting width with any garment piece of the knitting width of feel sample all has more differently, can not set the optimum plane No. to each garment piece.The inventor finds that even other conditions are identical, the plane No. of the length direction of knitted fabric also depends on knitting width and changes.In addition in addition, though the plane No. of the width of knitted fabric also depends on knitting width and changes, the influence of knitting width is less.

The specific embodiment
The optimum embodiment that is used for embodiment of the present invention below is shown.
Embodiment
Represent embodiment among Fig. 1～Fig. 4.Among the figure, 2 is design system, possesses the keyboard 6, mouse 8 of monitor such as colour picture monitor 4 and input usefulness etc., is connected via not shown LAN etc. and internet etc.Possess disc driver etc. in addition, can read from storage mediums such as CD-ROM, design system 2 is made up of suitable computer.The 10th, straight-bar machines, needle-bar number are 2 or 4 etc., the 16th, collator is for example cleaned, fulling milling or decatize processing etc., in dimension measurement operation 18, be determined at the sample 12～14 that is woven on the straight-bar machines 10 width and length, be width and length.
For a plurality of samples, width that is measured to and length are imported to the correction function generation portion 20 of design system 2.Correction function generation portion 20 is based on the length and the width of a plurality of samples, and the length function that generates and stores the lengthwise dimension of expressing coil is as the width function of the function of pin number and the width size of the expressing coil function as the pin number.These functions are for example functions of the combination of the kind of kind, the textile finishing of the yarn of target loop length, raw material and the thickness etc. of each coil of each braiding condition.Replace width and length in addition, also can import the length direction plane No. and the width plane No. of the knitted fabric of each sample to correction function generation portion each sample of input.That is,, can select to use the width of sample and length also to be to use plane No. arbitrarily as the inverse of coil dimension as the parameter of expressing coil dimension.In addition, though input lengthwise dimension and width size and generate length function and width function among the embodiment is lengthwise dimension owing to what depend on large percentage that the pin number changes, so also can not generate the width function.
In the design portion 19 of design system 2,, carry out the design of knit product based on input from keyboard 6 and mouse 8 or not shown LAN etc.Have 2 stages in the design of knit product, size in the initial stage through each garment pieces of input such as length and width.Size in this stage is specified by the length of cm unit or inch unit etc., and the data in this stage are called pattern data.Then, design portion 19 is transformed to the design data of knit product with pattern data, or is the weave data that can on straight-bar machines 10, handle with the design data Direct Transform.In this process, the width of garment piece and length are the knitting width of garment piece, promptly weave the radical of employed pin and the row number of garment piece according to length function and width functional transformation.
Fig. 2 representes the example of length function and width function, and transverse axis is represented the pin number, and the longitudinal axis is represented the plane No. X of length direction and the plane No. Y of transverse direction, and they all are the coil numbers on every cm.Among Fig. 2, length function is that curve, width function are straight line, but they both can be for curve also can be straight line, and it is the function storage of variable that these functions also can be used as with the pin number, or also to can be used as with the pin number be that the table of index is stored.
In the data of Fig. 2, using per 1 inch pin number is 12 straight-bar machines, and making the loop length of per 1 coil through plain stitch is 6.0mm, uses each 200 row of wool yarn braiding.Be based in addition carry out that decatize is handled and clean, the data of dry measured value during as textile finishing.The pin number of sample is 50,100,200,300 these 4 kinds, can know, vertical plane No. is according to the pin number and marked change, but horizontal plane No. not too changes.Measurable in addition, if, then indulging plane No. and horizontal plane No. greater than 300, the pin number all not too depends on the pin number.Therefore in the zone of pin number for example, can proofread and correct to vertical plane No. and horizontal plane No. and be necessarily greater than 300.Also can not use 4 kinds of samples in addition and use 3 kinds of samples etc.
As the reason of the data that obtain Fig. 2, be the original because knitting width difference of knitted fabric and character changes.Be that elongated knitted fabric stretches along longitudinal direction easily, the knitted fabric that width is big is difficult for stretching along longitudinal direction.In the above-mentioned patent documentation 1, obtain plane No., be the coil number of every specific length, this plane No. is applied to knitted fabric integral body at certain knitting width.So, then not necessarily obtain optimum plane No. if knitting width is different.With respect to this, obtain the knitting width (pin number) of knitted fabric and the relation between plane No. or the coil dimension, set the plane No. of the optimum after the influence proofreaied and correct knitting width, this is a characteristic of the present invention.Among Fig. 2, the row number of sample is 200 rows, is certain value, even but it is become for example 100 rows and 300 rows, also obtain the result identical with Fig. 2.Be that the pin number is the actual plane No. of decision, is the factor of the size of coil.
The algorithm that the expression plane No. is proofreaied and correct among Fig. 3.Be called here proofread and correct be because, in the process of row number and pin number of garment piece that with the size change in the pattern data is knitted fabric, the influence of adjusting pin number.The thickness and the raw material of the braiding condition of design system 2 storage knitted fabrics and the kind of yarn, for example yarn, reach data such as textile finishing condition, for the combination of these data, memory length function and width function.Be that length function, width function are the functions of combination of kind and the textile finishing condition of each braiding condition and yarn, but also can use more approximate function.
If the thickness of yarn or raw material change, the braiding condition changes or the textile finishing condition changes; Then can not be suitable for length function and the width function stored; Therefore correction function generation portion 20 is to the instruction of the new sample of design portion 19 outputs needs, and design portion 19 generates the weave data of samples 12～14.The kind of braiding condition here and textile finishing condition, yarn is the kind of the braiding condition in the actual production of knit product, used and textile finishing condition, yarn, and straight-bar machines 10 is the different for example 3 kinds of samples 12～14 of knitting needle number in view of the above.To these samples 12～14, on collator 16, implement and the actual same textile finishing of knit product, for example through manually measuring the width and the length of each sample.To measure the result to 20 inputs of correction function generation portion.The method of input can be directly to import the width and the length of knitted fabric, or also can with they be transformed to unit length coil number, be plane No. and importing.
Correction function generation portion 20 stores with kind and braiding condition, the textile finishing condition of yarn based on length function and the width function of input data generation Fig. 2.Based on the length function and the width function that generate, design portion 19 obtains row number and the pin number that needs for the length and the width of each garment piece in the pattern data.According to row number and the pin number obtained, weave actual knit product then.Can produce the knit product that is roughly the purpose size thus.Be used to make each program of handling of design system 2 execution graphs 3, design program,, be supplied to design system 2 via storage medium such as CD-ROM or conveyance ripple etc. through the knitting of embodiment.
The length of expression garment piece and the determining method of width among Fig. 4.The knit product 40 of Fig. 4 is made up of predecessor's sheet 41 and not shown back body sheet, sleeve 44,45, and 42 is body rib, and 46 is cuff, and these are all carried out ribbed knitting.Establish in addition predecessor's sheet 41 within it portion possess the decorative pattern that raw material are identical, color is different 43 of yarn.The knitting width X1 of predecessor's sheet for example confirms as Fig. 4 here, and length Y1 also confirms as Fig. 4.On the sleeve 44,45, for example as Fig. 4, confirm width X2 and length Y2, generally become big at armhole side width, so knitting width X2 is made as their middle values with respect to cuff 46.In addition among Fig. 4, knit product 40 is carried out tubular knitted, therefore the cylindrical fabric that knitting width is different weaves as sample.
The tubular knitted example of expression among Fig. 4, but also can consider through predecessor's sheet, back body sheet, about sleeve add up to 4 garment pieces that knit product 40 is carried out integral weaving.Under this situation, sample is not as cylindrical fabric but as jersey, changes knitting width and weaves a plurality of.
Among the embodiment, can the adjusting pin number to the influence of coil dimension, the row number and the pin number of decision knit product.Can weave knit product more simply thus near the size in the pattern data.
