Abstract
This study analyzes the form of sleeve heads, which is an important internal element that affects the appearance of jacket sleeves. It characterized sleeve head forms by investigating angles, materials, and a combination of formations for 50 sleeve heads. It conducted an appearance evaluation by comparing and analyzing the results. This paper develops a sleeve head appropriately for sleeve construction. The study results are as follows. First, the product was divided into three parts: based on, force receiving, and sleeve cap parts. There were four types of man's sleeve head: straight, arc, and curve A and B types. The woman's sleeve head had two types: straight and curve B type. Second, the feature of each type of sleeve head was analyzed. A straight type emphasized the based on part. An arc type highlighted the force receiving part while the based on part decreased. The sleeve cap part, force receiving part, and based on part were emphasized in the arc type sleeve head. Third, as a result of the appearance evaluation, each type was rank as straight type < arc type ${\leq}$ curve A < curve B. The straight type did not get positive results as it had extra ease when the sleeve head was attached to a Jacket Sleeve. The arc type was evaluated poorly due to an inappropriate sleeve cap composition. The curve type received an excellent overall outcome as it fit into the sleeve cap part well and highlighted the force receiving part in order to minimize front and back wrinkles. Therefore, the curve type made the resemblance of the jacket appearance perfect and closest to the sleeve pattern.
