"In fact, the 'washed silk' in many shops is not real silk, but fake silk made of polyester," says Chang Hsiu, a member of the Business Expansion Committee of the Fabric Promotion Association. Real washed silk refers to genuine raw silk which has passed through a water washing treatment. The friction of the treatment gives the material a pearl like gloss.
「其實許多市面上的水洗絲並不是真絲，只是人造纖維（Polyester）所做的仿絲」，紡織拓展會市場開發科專員張修表示，真正的水洗絲是指蠶絲經過水的沖擊處理，使得布料經過摩擦而產生一種珍珠般內斂的光澤，有種霧濛濛的效果。
