::: PBT Fiber :::
PBT、which belongs to one type of polyester、is a polymer produced from 1,4-butanediol which replaces the raw material glycol of PET. PBT has two more methyls (-CH2) than PET that results in lower coherence among molecules and provides the PBT fiber with flexibility to some extent. In the same time、due to being pulled、its molecular constitution will extend to become a β form from its conventional α form. When the pull force disappears、the β form will convert to the α form. Such a conversion ofα→β or β→α produces permanent flexibility by using conversion in molecular constitutions.

 

::: PBT纖維 :::

PBT與PET同屬聚酯纖維的一種,將原料乙二醇以1.4丁二醇取代所得的聚合物。PBT比PET多出二個甲基(-CH2-),造成分子間較低的凝集力,使PBT纖維具有相當程度的伸縮性。同時其分子構形因受拉會由平時的α型,伸長成β型,當拉力消除時即由β型轉回α型,此種α→β,β→ α的轉變是利用分子結構之轉變而產生持久彈性。

 

::: Side By Side ::: 

Able to be strongly twisted、resistant to reduction and the worsted-like appearance、best features the Side-by-Side Potential Shrinkable Fiber、which is thus quite applicable to popular fashions like women's suits.

      

 

::: 潛在捲縮性纖維 :::

可強撚、耐減量、具自然之梳毛調外觀,是Side-by-Side潛在捲縮性纖維最大的特色,也因此十分適合於女性套裝等流行服飾使用。

以製作方式而言,Side-by-Side潛在捲縮性纖維利用聚合度不同的兩種聚酯並列,複合紡絲加工而成,經追撚加熱形成收縮差距效應後產生扭力,得到如彈簧般捲縮、且有彈性之螺旋狀纖維。
