Application of matching displacement in structural design of trousers

A drafting of the trousers pattern is made within a rectangle with the sum of the front and back crutch depth lines as width and the pants as length.Based on this,a new design method called(″the) matching displacement″ is proposed to make changes to the trousers′ structural lines,that is,to make full use of the rectangle′s area and the cylinder′s superficial area to redesign the side seam and the inside leg seam.The experiments show that dint design by this method,whether changing the side seam lines,shifting the inside leg seam lines or changing either of them,the suitability and fitness of the trousers thus designed will be maintained provided that the trousers circumference remains unchanged.Obviously,this method has enriched the present designs of trousers′ structure.
