Abstract
The invention discloses a method for preparing a hollow textile with a core-spun yarn of short-staple wrapped microporous alkali-soluble polyester filament, which includes a foaming microcapsule preparation step, a preparation step of alkali-soluble chips containing foaming microcapsules, a melt foaming and spinning step, and a hollow textile preparation step. In the method for preparing the hollow textile with the core-spun yarn of short-staple wrapped microporous alkali-soluble polyester filament, a hollow yarn or a hollow fabric is made from a polyester filament having a microporous structure through alkali dissolution. The polyester filament having a microporous structure can effectively increase the contact area of the alkali dissolution and has the advantages of high dissolution rate, short dissolution time and complete dissolution. The hollow textile prepared from the hollow yarn or the hollow fabric obtained after dissolution has a comfortable hand feeling and has the characteristics of being fluffy, soft, warm and quick-drying.
