Claims40
A multicomponent fiber comprising:
- a first component comprising polyester, wherein at least 80 wt % of the polyester is recycled polyester, the first component having a melting point MP1;
- and a second component comprising polyester, wherein at least 80 wt % of the polyester is recycled polyester, the second component having a melting point MP2, wherein MP2 is less than or equal to MP1.
A fiber comprising:
- a component comprising polyester and a melting point-reducing additive, wherein at least 80 wt % of the polyester is recycled polyester, and wherein the component has a melting point of 70 to 180° C.
Batting comprising a fiber selected from:
- a multicomponent fiber comprising:
- a first component comprising polyester, wherein at least 80 wt % of the polyester is recycled polyester, the first component having a melting point MP1, and a second component comprising polyester, wherein at least 80 wt % of the polyester is recycled polyester, the second component having a melting point MP2, wherein MP2 is less than or equal to MP1, and
- fiber comprising:
- a component comprising polyester and a melting point-reducing additive, wherein at least 80 wt % of the polyester is recycled polyester, and wherein the component has a melting point of 70 to 180° C.
