一般整髮,主要利用髮夾、髮箍、髮簪或其他適於將頭髮定型、整束之器具。由於髮夾在夾束髮絲中,該夾體必須具有相當之抗彎折性,使得大部分業者會藉重於金屬彈簧等,該材質之選用主要係利用具有較佳之剛性與回復之彈性的金屬,但是此種金屬製成之夾體由於注重美觀性,又往往必須於該金屬上貼各種塑膠材質之裝飾片,來增加其花色、紋路與質感。 Generally, the hair is made up of hair clips, headbands, hairpins or other utensils suitable for shaping and tidying hair. Since the hairpin is in the bundled hair, the clamp must have considerable bending resistance, so that most of the industry will rely on metal springs, etc., and the material is mainly selected by using metal with better rigidity and recovery elasticity. However, due to the aesthetics, the clip made of such metal often has to be decorated with various decorative pieces of plastic material to increase the color, texture and texture of the metal.
金屬因國際原物料高度波動使得生產成本大幅增加,貼附有塑膠材質裝飾片的金屬在拋棄不使用時,不易以單純金屬之分類回收,往往必須經由溶劑、燃燒等方式取回金屬,因此前述之塑膠裝飾品又容易產生毒性等環境公害,而且此類金屬製成之夾體,由於塑膠裝飾片之貼附製作過程繁複,而且金屬部分容易生鏽,尤其經常與沐浴之多水分環境接觸,經常沾附水分而容易受潮而更加深生鏽之機會。 Due to the high fluctuation of international raw materials, the production cost is greatly increased. When the metal with the plastic decorative piece is discarded, it is not easy to be recycled by simple metal. It is often necessary to retrieve the metal through solvent, combustion, etc. The plastic decorations are prone to environmental hazards such as toxicity, and the clips made of such metals are complicated in the process of attaching the plastic decorative sheets, and the metal parts are prone to rust, especially in contact with the moisture environment of the bath. A chance to get wet and often get wet and rust more.
先前技術在塑膠材質中,雖有業者嘗試以單一塑膠原料如ABS樹脂(丙 烯腈-苯乙烯-丁二烯共聚物)、聚碳酸酯(Polycarbonate,簡稱PC)或是藉由壓克力(聚甲基丙烯酸甲酯Polymethylmethacrylate)製造,但是此種材質無法同時具備有延展性、回塑性及韌性,而使得容易出現斷裂、摺白、老化等現象。 Prior art in plastic materials, although some operators try to use a single plastic raw material such as ABS resin (C Acrylic-styrene-butadiene copolymer), polycarbonate (Polycarbonate, PC for short) or made of acrylic (polymethylmethacrylate), but this material cannot be ductile at the same time. , plasticity and toughness, which makes it easy to break, white, and aging.
