Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1
This embodiment will be described in detail with reference to fig. 1. The environment-friendly water-based composite embossed single-sided velvet according to the present embodiment includes a velvet layer 1, a first water-based adhesive layer 2, a bundled ultrafine fiber layer 3 filled with a foamed water-based polyurethane material, a second water-based adhesive layer 4, and a base cloth layer 5, which are sequentially disposed.
The first water-based adhesive layer 2, the bundle-shaped superfine fiber layer 3 and the second water-based adhesive layer 4 are provided with air holes. So that the whole environment-friendly water-based embossing single-sided velvet has air permeability. One side of the flannelette layer 1, which is far away from the first water-based adhesive layer 2, is provided with a flannelette surface with flannelette patterns.
The flannelette layer 1 is formed by sequentially stringing and covering 100D/144F surface yarns and 150D/48F bottom yarns through weft knitting and raising, and a layer of three-proofing finishing agent is attached to the single-side flannelette fabric. The three-proofing finishing agent is used to make the fabric have three-proofing function. And (3) performing processes such as raising, napping, shearing and the like on one side of the 100D/144F surface yarn, and forming a napped surface on the surface.
