  • Patent number: 10246807
    Abstract: A method for manufacturing a composite warm-keeping textile structure includes the steps of: applying an elastic gripper-puffing mechanism to perform puffing operations upon opened cotton fibers for forming at least one puffy fiber agglomerate; applying the elastic gripper-puffing mechanism to grab unit fiber agglomerates from the puffy fiber agglomerate and further to drop the unit fiber agglomerates onto a first cloth layer on an operational platform; vibrating the operational platform to have the unit fiber agglomerates to be evenly distributed over the first cloth layer, so that the unit fiber agglomerates are formed as a fiber agglomerate distribution layer adhered onto the first cloth layer; and, having a second cloth layer to cover the fiber agglomerate distribution layer, so that the first cloth layer and the second cloth layer clamps together the fiber agglomerate distribution layer in between to form the composite warm-keeping textile structure.

  • Publication number: 20120196101
    Abstract: The present invention provides a recyclable vapor-permeable waterproof laminate which has an outer layer and an inner layer. The outer layer is made of woven or knitted polypropylene (PP) material, and the inner layer is a polyethylene (PE) or polypropylene (PP) membrane, between which a thermal adhesive primarily made of polypropylene (PP) is provided to bond them together. The laminate of the present invention is not only able to serve as performance fabric but is also eco-friendly because the chemical structure of the materials (i.e., PP and PE) from which it is made consist of only carbon and hydrogen, and thus they will not generate toxic gas even though they are incinerated after disposal.
