Description

Technical Field

[0001] This utility model relates to a light-blocking and wrinkle-resistant polyester fabric, belonging to the field of light-blocking fabric technology. Background Technology

[0002] Polyester fabric is widely used in curtains due to its high strength, good abrasion resistance, and easy washing. However, polyester fabric has drawbacks such as poor light-blocking and wrinkle resistance. Especially since curtains frequently change shape and are rolled up, the fabric folds, and if the wrinkle resistance is poor, creases will appear on the surface of the curtain fabric after a period of use, affecting the appearance and user experience. Therefore, how to develop a light-blocking and wrinkle-resistant polyester fabric for curtains has become a problem to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a light-blocking and wrinkle-resistant polyester fabric that has the effects of light blocking and UV protection, and the elastic core-spun yarn used makes the fabric easy to recover after folding.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] The present invention relates to a light-blocking and wrinkle-resistant polyester fabric, comprising a composite outer layer, a TPU black light-blocking film layer, and an inner layer.

[0006] The outer layer is woven from a first elastic core-spun yarn, which includes a first core yarn and a first covering fiber layer covering the outside of the first core yarn. The first core yarn is an elastic filament, and the first covering fiber layer is a fully dull polyester filament.

[0007] The inner layer is woven from a second elastic core-spun yarn, which includes a second core yarn and a second covering fiber layer covering the outside of the second core yarn. The second core yarn is an elastic filament, and the second covering fiber layer is a flame-retardant fiber.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the surface of the surface layer away from the TPU black light-blocking film layer is coated with a hydrophobic layer.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the inner layer is coated with a nano silver / polyurethane electrospun film on the side surface away from the TPU black light-blocking film layer.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic filament is spandex filament.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the flame-retardant fiber is flame-retardant polyester fiber.

[0012] The beneficial effects of this utility model are as follows: The light-blocking and wrinkle-resistant polyester fabric involved in this utility model uses elastic core-spun yarns for both the outer and inner layers, giving the fabric elasticity and allowing it to quickly recover its shape after folding, thus providing a wrinkle-resistant effect. The use of fully matte polyester filaments gives the fabric a UV protection effect. Furthermore, the TPU black light-blocking film layer provides the fabric with excellent light-blocking properties.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] Combination Figure 1 This embodiment will be described in detail. The light-blocking and wrinkle-resistant polyester fabric involved in this embodiment includes a composite outer layer 1, a TPU black light-blocking film layer 2, and an inner layer 3, which are specifically composited by hot melt adhesive web film.

[0019] The outer layer 1 is woven from a first elastic core-spun yarn, which includes a first core yarn and a first covering fiber layer covering the outside of the first core yarn. The first core yarn is an elastic filament, and the first covering fiber layer is a fully dull polyester filament. The elastic filament used is spandex filament.

[0020] The inner layer 3 is woven from a second elastic core-spun yarn, which includes a second core yarn and a second covering fiber layer covering the outside of the second core yarn. The second core yarn is an elastic filament, and the second covering fiber layer is a flame-retardant fiber. The elastic filament used is spandex filament, and the flame-retardant fiber used is flame-retardant polyester fiber.

[0021] The TPU black light-blocking film is prepared by uniformly mixing 30 parts of polyurethane, 8 parts of low-density polyethylene, 20 parts by weight of carbon black, 30 parts by weight of emulsifier, 8 parts by weight of titanium dioxide, 10 parts by weight of nano-gelatin microspheres, and 5 parts by weight of phenyl salicylate, followed by extrusion blow molding. The parts obtained are by weight. The nano-gelatin microspheres used are nano-gelatin microspheres with a particle size of 150 nanometers. The TPU black light-blocking film can be prepared by calendering, casting, or extrusion. Extruders can be used for blow molding or direct extrusion using a slit die; in this embodiment, extrusion blow molding is used to produce the black and white light-blocking film.

[0022] Example 2

[0023] Combination Figure 2 This embodiment will be described in detail below. The light-blocking and wrinkle-resistant polyester fabric involved in this embodiment differs from that in Embodiment 1 in that the surface layer 1, away from the TPU black light-blocking film layer 2, is coated with a hydrophobic layer 4. Due to the use of titanium dioxide, it has a UV protection effect. The zinc oxide used has antibacterial properties. A base coating is formed by combining epoxy resin and polydimethylsiloxane (PDMS). Hydrophobic nano-titanium dioxide (TiO2) is prepared by modifying it with a titanate coupling agent and then composited with PDMS to construct the micro-nano structure of the coating surface, forming the hydrophobic layer 4.

[0024] Of course, the hydrophobic layer 4 can also be a PTFE microporous membrane composited with an adhesive phase.
