Continuity Research Of The Donghua Basic Block

Through many years' accumulation and refining, the Donghua basic block, based on scientific research and the theory of basic block, according to Chinese female body shape was established in 1998. And after 10-year's, the amendment of Donghua basic block which made by the changes of the human body reflect the current characteristics of human body exactly. It now reflects the body characteristics of the size designation of 160/84,but its series of clothing pattern grading technology needs to be proved to fit for other size designations such as 155/80,165/88,170/92.The paper is just about to be put forward based on that.The paper uses the method of theorization and practice combined. It has seven parts specificly:1. To analyse the body characteristics of 215 junior women.Based on the chest circumference requirement of 77.5—93.5cm,159 effective data were gotted after taking advantage of dimensional scanner measured 215 junior women,and classified on chest first. Means Testing and variance components is to be done by statisticas.2. To analyze the clothing pattern grading technology, and contrastive study the basic principles of pattern grading. The field theory of the garments industry pattern grading is the most fundamental principle of similarities. In the pattern grading technologies,one is the grading based on algorithm, another is incision and threaddrawing therapy.3. To use a variety of grading ways to study Donghua basic block. These ways include incision and threaddrawing therapy, chest ratio method,and the seventh edition of the Japanese culture basic block.And the initial express edition of Donghua basic grading block is gotted by a comprehensive approach.4. To prove the initial express edition of Donghua basic grading block.Within the chest scope of the female undergraduate,78cm-81cm(7),86cm-89cm(23),90cm-93cm(13), a kind of clothing is to be weared for the experiment. Cased for everyone. Then, the size of the cad drawing on the amendment to the structure figure.5. To study the coverage of the initial express edition of Donghua basic grading block for women body characteristic of size designations.To collecte the data and study the tendency of dispersion of the data. To study the coverage of the initial express edition of Donghua basic grading block for women body characteristic of size designations.6. To revise the initial express edition of Donghua basic grading block based on the correction test.7. To improve and perfect the DRESS-FROM of 155/80Y and 165/88Y based on the revised express edition of Donghua basic grading block and the making of sample dress.The revised express edition of Donghua basic grading block is gotted based on the correction test,and the DRESS-FROMs of 155/80Y and 165/88Y is improved and perfected. The revised express edition of Donghua basic grading block reflects the body characteristics of the different size designations,and the improved DRESS-FROMs are matched with the revised express edition of Donghua basic grading block.This improves and perfects the DRESS-FROM system which is matched with the theory of Donghua bsaic block.
