基於捲繞與氈化之密度變化性質的紡織成品製作系統

Abstract

FeltingReel是一種軟製造系統，讓使用者能創造具有不同結構強度、一體成形的3D非織造紡織品。我們的系統首先將羊毛線捲繞到一個中心線軸上，形成基本形狀，並使用帶倒鉤的針進一步塑形，增加可製造出的3D物件形狀與細緻度。藉由控制捲繞張力和戳刺時間等方式，我們的系統得以改變物件特定目標區域內的密度，製造不同的結構強度。具體而言，我們的系統使用環繞在中心旋轉軸周圍的Stewart平台來控制捲繞和針氈的傾斜度。此外，我們的系統還可以通過更換可拆卸的旋轉軸來形成具有中空內部結構的不同基本形狀。論文中我們研究了不同形狀的戳針、戳刺頻率、捲繞方向與張力對物件密度、結構強度和製造時間的影響。其中我們提出了三種結合氈化和捲繞的方式來製造相同形狀的物件，並製作兩種示例形狀來評估不同方式的製造表現和最終產品。最後我們展示了使用我們的系統製作的幾個物件，藉此討論了此製造系統的能力以及限制。

FeltingReel is a soft fabrication system that allows users to create a 3D non-woven textile with various structural strengths. Our system coils wool yarn onto a central reel to form a basic shape and uses actuated barbed needles to refine it. By controlling the coiling tension and the felting times, our system varies the density of the workpiece in a target area to achieve various structural strengths. Specifically, our system controls the tilt of coiling and felting using a Stewart platform around a motorized rotating reel. Our system also allows different basic shapes with hollow internal structures to be formed by changing the detachable reel core. We investigate the effects of different felting needles, frequencies, and coiling directions that influence the density, structural strength, and fabrication time of a workpiece. We propose three methods to combine felting and reeling. We evaluate their performances and final products by producing two example workpieces using our system. We demonstrate several objects made by our working system and discuss its capabilities and limitations.
