Background

Loose garments have a large market share, affected by the fashion trends of garments. The current plate making method of loose clothing mainly comprises the following three steps: firstly, a vertical cutting method: a method for making templates by utilizing tools and materials such as a three-dimensional model, white grey cloth, a pin and the like, which is mostly used for hanging, hanging and fluffy night dress and stage dress platemaking, and some loose dress adopts the method, so that the method is not used for carrying out loose dress platemaking in enterprises at present, and has low popularity; secondly, a prototype method: the method is characterized in that a Japanese cultural type clothing prototype is adopted to manufacture loose clothing, a female cultural type jacket prototype is firstly manufactured, and then chest circumference loosening is performed on the basis of the prototype, so that the adoption rate of the method in enterprises is not high due to the fact that the jacket prototype needs to be drawn or prepared in advance; thirdly, a proportion distribution method: the proportion distribution method is a method which is most used when the clothing manufacturing industry of China makes boards and cuts at present, and the method refers to a Japanese chest degree method, and the clothing cutting method is created by taking the actual chest circumference of the ready-made clothing as a base number. The proportion distribution method is used for making patterns of men and women's coats, jackets, trousers and the like, and loose clothes are also used for proportion distribution;

the prior clothing platemaking method has the following problems:

1. although the vertical cutting method is relatively visual, the plate making process is relatively complicated due to the multiple procedures of consuming materials, copying the plane paper patterns and the like, and the copied plane paper patterns are also properly corrected. The main problems are long time consumption and uneconomical; 2. when the prototype method is adopted to make loose clothing, operations such as chest circumference size adding and releasing, sleeve size adding and releasing are needed, and the accuracy and stability of clothing modeling are insufficient; 3. the proportion distribution method calculates the size of each part through a certain formula proportion, is a generalized plate making method, lacks the method of balancing clothes bodies such as shearing, gathering and the like, and has the advantages that the accuracy and the balance of the modeling are required to be improved when loose clothing plate making is carried out by the method; therefore, we propose a plate making method of body sleeve flexible loose clothing.

SS3, taking 2cm from the shoulder and neck point to the shoulder point, and respectively making alignment mark points on the front and rear small shoulder lines;

s7, forming a basic sleeve arc line of a large sleeve piece and a small sleeve piece of the two sleeves: horizontally overturning and copying the front and rear sleeve arches, overlapping the bottom end points of the front and rear sleeve arches with the intersection point of the sleeve central line auxiliary line and the sleeve fertilizer line, generating 2 intersection points of the copied front and rear sleeve arches and the original sleeve arches, respectively leading vertical lines downwards from the 2 intersection points to intersect with the cuff line, finally respectively making two parallel lines at the left and right 3cm of the vertical line led by the intersection point of the two front sleeve arches, deleting redundant arches, and forming two-sleeve large-sleeve-piece basic sleeve arches and two-sleeve small-piece basic sleeve arches;

s8, deleting the folded part of the front sleeve;

s9, drawing a splicing line: two parallel lines are respectively 1.2cm above and below the cuff line, and the upper parallel line extends to the right 5cm; 1.5cm and 1.8cm are used as circles on the intersection points of the two front sleeve seam auxiliary lines and the sleeve elbow lines; the intersection point of the two front sleeve seam auxiliary lines and the cuff line is rounded by 0.7cm and 5cm; respectively drawing a front sleeve seam line of the big sleeve piece and a front sleeve seam line of the small sleeve piece; the front sleeve split stitch line of the big sleeve and the small sleeve generates two intersection points with the cuff line, the midpoint of the two intersection points is taken as a circle center, a circle is taken as a radius of 14.5cm, and the circle center is connected with the intersection point of a parallel line below the cuff and the circumference; taking the intersection point of the auxiliary line of the back sleeve seam and the sleeve fertilizer line as a center point and taking 5cm as a radius to make a circle; taking the intersection point of the back sleeve seam auxiliary line and the sleeve elbow line as a center point, taking 3cm as a radius as a circle, taking the intersection point of the cuff line and the auxiliary line below the cuff as a circle center, taking 1cm as a radius as a circle, and connecting the back sleeve seam auxiliary line of the large sleeve piece and the small sleeve piece; the front end of the small sleeve arc line descends by 0.7cm, the small sleeve arc line is adjusted, and the back stitching line of the large sleeve and the small sleeve is drawn smoothly.
