眼影質地的爆炸性增長——來自 “奶油味的” 從霧面和厚實的閃粉到膏狀到粉狀的配方——迫使工廠超越通用的刷子設計. 設計眼影刷現在的問題是 “表面能” 和 “纖維摩擦。”
根據配方調整纖維
適用於霧麵粉: 這些都需要高 “撿起” 和 “付清” 比率. 工廠使用捲曲纖維 (具有微觀波的纖維). 這些波浪形成微小的口袋， “陷阱” 粉末顆粒, 允許使用者在使用前去除多餘的部分.
適用於閃光和金屬色: 閃光是平的, 板狀顆粒. 捲曲的纖維會粉碎它們. 反而, 工廠直用, 光滑錐形纖維. 它們的作用就像一把平鏟, picking up the metallic flakes and laying them flat on the eyelid for maximum light reflection.
For Creams and Liquids: Here, the priority is Chemical Resistance. Factories use PBT (Polybutylene Terephthalate) fibers, which do not swell when exposed to the oils and emollients found in cream shadows.
這 “Dressing” Process
The secret to a high-end eyeshadow brush is the “hand-dressing” of the hair bundle. 在工廠裡, skilled artisans “tap” the fibers into a mold to create the shape rather than cutting them with scissors. Cutting the tips destroys the natural taper of the fiber, resulting in a scratchy feel. 一個 “zero-cut” edge is the hallmark of a premium eyeshadow tool.
