Described fabric sorting technique is on the basis that fabric performance is analyzed, and the performance parameter that obtains is carried out factorial analysis, then uses clustering method that fabric is classified, wherein,
Described factorial analysis, that 18 performance index values are carried out dimension-reduction treatment, eliminated simultaneously correlativity mutual between former variable, it comprehensively is 4 common factors the most at last, is designated as C1, C2, C3, C4 observes the load of each common factor on each performance index, with the bending of 4 common factors difference called afters, shear factor, the thick and heavy factor, broadwise elongation factors and warp-wise elongation factors
When definite optimal classification is counted, selecting mixing F normalized set to obtain the optimal classification number is 7 classes, after cluster is finished, observe fabric and characteristic of property thereof, analyze the denominator of fabric of all categories, as the foundation of subsequent configuration sewing processing technology, when in the situation that sample constantly expand, dynamically adjust aforesaid cluster process, so that classification is more reasonable;
Orthogonal experimental method is adopted in described optimum sewing technology combination, for different classes of typical fabric, under different sewing technology conditions, design orthogonal test, then pass judgment on the sewing wrinkle grade of sewing sample, on the test result analysis conspicuousness of working process parameter on result impact of respectively being sewed, obtain the optimum sewing technology combination of 7 types of fabrics being represented by following table
For the fabric of UNKNOWN TYPE, judge that in described 7 types of fabrics which kind of it belongs to, and then mates such best sewing technology to it.
The invention has the beneficial effects as follows, according to fabric performance fabric is classified, and the fabric classification is carried out the coupling of sewing technology accordingly, meet the work habit that the clothes processing industry is manually determined the sewing processing technology.Adopt simultaneously computer system to realize the automatic dynamic classification of fabric, the differentiation of fabric classification and the Auto-matching of sewing technology have solved the difficult point aspect garment material sewing technology designing technique.
Description of drawings
Fig. 1 is the implementation procedure process flow diagram that garment material sewing technology of the present invention generates
Embodiment
As shown in Figure 1, the garment material sewing technology generation method of the present invention's exploitation mainly is according to physical properties of fabric it to be carried out on the basis of category division, realizes in conjunction with the Rapid matching of the optimum sewing technology combination of fabric of all categories.
For the test of fabric performance, mainly refer to the physical and mechanical property of fabric, and the index such as thickness, weight.The fabric performance that the present invention adopts mainly is by FAST Fabric Style instrument, 18 performance index that Measurement and Computation obtains under the standard climate condition, comprise thickness (T2, T100, ST), bending property (E5-warp, E5-latitude, E latitude 0-warp, E latitude 0-latitude, E through 00-through, E through 00-latitude, EB5), cutting performance (G), tensile property (C-warp, C-latitude, B-through, B-latitude), the weight (W) of formability (F-warp, F-latitude) and fabric etc.
The present invention has adopted clustering method for the division of fabric classification.Owing to having correlativity between 18 parameters that obtain, and number of parameters is many, in order to simplify subsequent treatment, and reduces the error that causes owing to the multicollinearity that exists between variable, adopt factor-analysis approach, 18 performance index values are carried out dimension-reduction treatment, eliminated simultaneously correlativity mutual between former variable, it comprehensively is 4 common factors the most at last, be designated as C1, C2, C3, C4.Observe the load of each common factor on each performance index, with the bending of 4 common factors difference called afters, shear factor, the thick and heavy factor, broadwise elongation factors and warp-wise elongation factors.
The present invention uses the K-means clustering procedure to carry out the division of fabric classification on the basis of above factorial analysis.The K-means clustering procedure needs to determine in advance the optimal classification number, adopts among the present invention and mixes the optimal classification number that F statistic (Mixed-F) is calculated cluster analysis.The concentrated expression of Mixed-F statistic the statistic of degree of scatter between tightness degree and class in the class of all variablees, its value is larger, illustrates that contact is tightr in the class of all variablees, falls apart and contact is overstepping the bounds of propriety between class.It is 7 classes that calculating Mixed-F statistic obtains the optimal classification number.After cluster is finished, observe fabric and characteristic of property thereof, analyze the denominator of all types of fabrics, as the foundation of subsequent configuration sewing processing technology.In the situation that sample constantly expands, can dynamically adjust aforesaid cluster process, so that classification is more reasonable.
The present invention adopts orthogonal test to obtain for the configuration of the optimum sewing technology of fabric of all categories.Selection is carried out orthogonal experiment to the most obvious several technological parameters of sewing quality influence, obtains the optimal sewing technology parameter of fabric of all categories as shown in table 1.
Table 1
The present invention is after the best sewing technology combination that obtains all kinds of fabrics, fabric sample for the unknown, judge by discriminant analysis method in the above 7 class fabrics which kind of it belongs to, and then it is mated such best sewing technology, thereby the realization fabric is made the quick generation of processing technology.
