Embodiment 1

[0010] Example 1: A polyurethane TPU black full shading film is made of a masterbatch blown film made of 74% polyurethane TPU, 18% carbon black and 8% chrome black powder, and its thickness is 0.8~ 5 filaments, with a width of 500-3300 cm, the coloring degree of the carbon black is 140%, and the fluidity is 26-28.

Embodiment 2

[0011] Example 2: The polyurethane TPU black full shading film described in Example 1 was applied to the curtain fabric, and was pasted between the curtain fabric surface and the bottom through PUR hot melt adhesive or PU glue. Choose 70g Chunyang Fleece and the required surface cloth, and stick the TPU polyurethane black full shading film in the middle with PUR hot-melt adhesive. The curtains made are soft and drapey. Using polyurethane black full shading film, the double-sided composite curtain fabric with hot melt adhesive can achieve 100% shading, 100% washable and dry cleaning, 100% environmental protection, and can withstand strong sunlight in summer and reduce indoor temperature, keeping warm and moisturizing in winter.

Embodiment 3

[0012] Example 3: The polyurethane TPU black full light-shielding film described in Example 1 was applied to the tent and the sunshade cloth, which has good waterproof performance and can be breathable and watertight. The characteristics of polyurethane black shading film, summer waterproof shading and strong light exposure, TPU black full shading film is made on the product, which has the function of absorbing light, not reflecting but not transmitting light, cooling, and playing the effect of waterproof, heat preservation and moisturizing in winter. Therefore, it is just right to use it on tent shade cloth.
