[0021] Example
[0022] Please refer to the instruction manual attached. Figure 1 As shown, the instruction manual is attached. Figure 1The diagram shows a layered structure of a wool-feel waterproof and breathable fabric according to this utility model. It consists of a polyester wool-feel fabric layer 1 and a PU waterproof and breathable membrane 3 laminated to the bottom surface of the polyester wool-feel fabric layer 1. The polyester wool-feel fabric layer 1 and the PU waterproof and breathable membrane 3 are bonded together by a hot melt adhesive layer 2. (See attached specification.) Figure 2 As shown, the polyester wool-like fabric layer 1 serves as the surface layer, which is woven with composite yarn as warp 11 and polyester elastic yarn as weft 12 in a one-up-two-down pattern. There are gaps between the interlacing points of the warp 11 and weft 12, and the density of warp 11 is 55 threads / cm², while the density of weft 12 is 48 threads / cm², ensuring complete moisture permeability and breathability. The composite yarn has a fineness of 75D, and each yarn consists of 48 monofilaments. (See attached instruction manual.) Figure 3 As shown, the composite yarn is composed of a polyester low-elasticity yarn and a filament yarn, which are then entangled and dyed at high temperature. The entanglement method involves using high-pressure air to disrupt and entangle the fibers in the yarn, forming network nodes. There are 80-90 nodes per meter. It is not a winding method. Dyeing is performed using a flow dyeing machine at a temperature of 120-135 degrees Celsius. The polyester low-elasticity yarn has a specification of 75D / 48F and a shrinkage ratio of 2-3%. The filament yarn has a specification of 50D / 36F and a shrinkage ratio of 7-8%. During high-temperature dyeing, the different shrinkage ratios of the polyester low-elasticity yarn and the filament yarn create a network structure... Figure 3 The fabric has a wool-like feel; the polyester elastic yarn has a fineness of 150D, and each yarn consists of 72 monofilaments; the hot melt adhesive layer 2 is composed of several adhesive dots with gaps between adjacent dots; the adhesive dots have a diameter of 650µm, a height of 150µm, and 720 mesh per square inch; the PU waterproof and breathable membrane is a hydrophilic film that absorbs moisture from the body and transfers it to the outer layer, then discharges it through the yarn gaps of the polyester wool-like fabric layer 1.
[0023] This wool-like waterproof and breathable fabric uses a PU waterproof and breathable membrane to give the product a waterproof and breathable effect, making ordinary waterproof and breathable fabrics feel like wool, enhancing the sense of luxury in clothing, while the price is cheaper than real wool, making it cost-effective.
[0024] It should be emphasized that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
