2 indirect applications

Sweater clothes knitting and forming product has its unique braiding realization method, is different from cutting sewing clothing, therefore right It is used in the pattern of some woolens styles, is not that simple shape replicates, but pattern is combined with knitting and forming method.

Tippet and trousers pattern style finished product and pattern tuck inside the sleeve as shown in figure 4, the method that sleeve and trouser legs all use cutting spread It makes, the non-forming clothes way of the pattern is cutting formation sleeve piece curved shape, and need to be divided into 2 sleeve half, then partly by 2 sleeves It is a sleeve that piece sutures respectively, but knitting and forming is to realize sleeve piece curved shape using part braiding, and be not necessarily to be divided into 2 Entire sleeve piece directly can be knit out, working needle is gradually reduced and be stepped up by being used in sleeve piece both sides by a sleeve half Several local weaving manners keeps both sides length of a curve shorter than intermediate, and the principle of cutting spread is identical with province, thus model shape and Pattern is different, cannot directly apply pattern, need to record the critical size during paper pattern forming, and is applied to sweater model, Critical size includes the length of run and expansion spacing at 12 cutting spread positions, the interior outside arc length after the completion of paper pattern forming, Non- cutting spread position straight length, pattern spot size are as shown in table 1.

Length of run directly affects the bending degree of curve, and length of run is bigger, and curve is more bent, and numerical value should meet public affairs Formula:Σ lengths of run=outer arc line length-inner arc line length need to determine that the expansion of every evolute is grown according to pattern shape needs Degree；Spacing is unfolded to pattern shape also important, Fig. 5 is shown in influence of the expansion spacing to shape, and 3 evolute spacing are not Together, cause inside and outside arc curvature of a curve different, when the smaller position of spacing is relatively concentrated, the larger i.e. shape bending of camber line curvature is more apparent, Therefore the expansion spacing of the length of run and adjacent evolute of each evolute during paper pattern forming, will do detailed note Record.

For cutting apparel pattern design, obtain final pattern, intermediate data without recording, but if with It in molding clothes, then needs to record the critical data during paper pattern forming, be compiled for making molding in knitting software It knits pattern and obtains weaving list.Fig. 6 is that model technique list and local size mark, from Fig. 6 (b) it can be seen that model face sheet Shape from cut pattern it is different, by cutting spread with save replace, save merge after then reach with cut pattern shape identical result, be molded Braiding is completed to also achieve province's merging simultaneously, is made and is required according to model, each intersection point will define its laterally with directly to size, Directly spacing 4.4cm, length of run can be such as unfolded according to length of run, spacing equidimension numerical value to size setting in this paper samples 5/4/6/5/4/3/2cm, outer arc line length 106.5cm etc., and lateral dimension 16.8cm etc. then needs to establish equation progress size It calculates.

Since breaking up point is point on cutting spread linea oblique anterior, each point lateral dimension can be oblique according to the oblique line before cutting spread Rate calculates:

K=(XH-XL)/(W-N) (1)

In formula:K is oblique line slope；W is outer arc line length；N is inner arc line length；

XH is that sleeve is wealthy；XL is SLEEVE OPENING.

X=28-D × n × k (2)

In formula:X is breaking up point lateral dimension；D is expansion spacing；N=0,1 ... 11.

K=(28-15.6)/(106.5-53)=0.23178 is obtained by formula (1), is opened up herein according to pattern measurement The standard width of a room in an old-style house obtains X=28-4.4 × n × 0.23178 away from for 4.4cm by formula (2), retains 1 decimal and obtains 12 breaking up point transverse directions Dimensional values, pattern breaking up point lateral dimension are as shown in table 2.

According to model size and finished product density, this paper finished product densities are 6.15 stringers/cm × 4.12 turn/cm, and software can be certainly Dynamic that technique list is calculated, by technique list, locally braiding stops needle and widening formula manual amendment, obtains model technique list, sees Fig. 6 (a), model file is exported into Computerized flat knitting machine, finished product is obtained after braiding, finished level figure is as shown in Figure 7.
