Abstract
Description
Technical Field
[0001] The utility model relates to an easily dyeable polyester composite cloth, belonging to the technical field of textile fabrics. Background Art
[0002] The temperature for dyeing polyester with disperse dyes is typically around 130°C, making it more difficult to dye at higher temperatures. Currently, there are carrier-free polyesters on the market that can be dyed with disperse dyes at room temperature and pressure. These are achieved through copolymerization, block copolymerization, or blending, allowing polyester to be dyed with disperse dyes without a carrier and at temperatures below 100°C. Examples include polyester fibers (PETI) and polybutylene terephthalate (PBT) blends, made by copolymerizing small amounts of di-acids such as isophthalic acid or diols with terephthalic acid and ethylene glycol. The challenge is how to use easily dyeable polyester to create composite textile fabrics for clothing. Utility Model Content
[0003] The purpose of the utility model is to provide an easy-to-dye polyester composite cloth, so that the fabric prepared by the easy-to-dye polyester fiber has an easy-to-dye effect, and the antibacterial and skin-friendly fabric used improves the comfort of the prepared clothing.
[0004] In order to solve the above technical problems, the purpose of this utility model is achieved as follows:
[0005] The utility model relates to an easy-to-dye polyester composite fabric, comprising a composite easy-to-dye polyester fabric layer and an antibacterial skin-friendly fabric layer;
[0006] The easy-to-dye polyester fabric layer is woven from easy-to-dye polyester core-spun yarns, and the easy-to-dye polyester core-spun yarns include core yarns and easy-to-dye polyester fibers covering the outside of the core yarns.
[0007] On the basis of the above solution and as a preferred solution of the above solution: the easily dyeable polyester fabric is a planar three-way fabric, which is formed by three groups of easily dyeable polyester core-spun yarns interwoven at an angle of 60° to each other.
[0008] On the basis of the above solution and as a preferred solution of the above solution: the core yarn is high-strength polyester filament or high-strength nylon filament.
[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the antibacterial skin-friendly fabric layer is woven with antibacterial skin-friendly core-spun yarn, and the antibacterial skin-friendly core-spun yarn includes antibacterial core yarn and cotton fiber coated on the outside of the antibacterial core yarn.
[0010] On the basis of the above solution and as a preferred solution of the above solution: the antibacterial core yarn is nano zinc oxide modified polyester low-elastic network yarn; the surface of the cotton fiber is attached with an antibacterial agent.
[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: a hollow fabric layer is arranged between the easy-to-dye polyester fabric layer and the antibacterial and skin-friendly fabric layer; the hollow fabric layer is woven with hollow warm yarns as warp and weft yarns, and the hollow warm yarns include hollow polyester fiber yarns and aerogel fiber yarns twisted in parallel.
[0012] The beneficial effects of the present invention are as follows: the outer layer of the easily dyeable polyester composite fabric is woven with polyester fiber core-spun yarn, making the fabric layer easy to dye. In addition, the antibacterial and skin-friendly fabric layer used makes the clothing made of the composite fabric have antibacterial and skin-friendly effects, thereby improving wearing comfort. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 1 is a schematic structural diagram of the easily dyeable polyester composite fabric involved in Example 1;
[0014] Figure 2 It is a schematic structural diagram of the easily dyeable polyester composite fabric involved in the second embodiment.
[0015] The markings in the figure are as follows: 1-easy-to-dye polyester fabric layer; 2-anti-casting skin-friendly fabric layer; 3-hollow fabric layer. DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] Example 1
[0018] Combine Figure 1 This embodiment is described in detail. The easily dyeable polyester composite fabric of this embodiment comprises an easily dyeable polyester fabric layer 1 and an antibacterial, skin-friendly fabric layer 2, which are bonded together via a hot-melt adhesive web. The easily dyeable polyester fabric layer 1 is interwoven with easily dyeable polyester core-spun yarn, which comprises a core yarn and easily dyeable polyester fibers covering the core yarn.
[0019] The easy-to-dye polyester fabric layer 1 uses easy-to-dye polyester core-spun yarn. The easy-to-dye polyester fiber used has the effect of being easy to dye at low temperatures, making it easier to dye the easy-to-dye fabric layer 1 and reducing costs.
[0020] Furthermore, to enhance the tear resistance of the easily dyeable polyester composite fabric of this embodiment, the easily dyeable polyester fabric 1 is a planar triaxial fabric, comprised of three sets of easily dyeable polyester core-spun yarns interwoven at a 60° angle. The 60° angle between the three yarns ensures the triaxial fabric exhibits isotropic mechanical properties. Regardless of the direction of force applied to the fabric, its deformation exhibits uniform, equal strain, overcoming the significant discrepancy between shear and tensile strength found in biaxial fabrics at a 450° angle.
[0021] Furthermore, to increase the strength of the easily dyeable polyester fabric layer 1, the core yarn is made of high-strength polyester filament or high-strength nylon filament. In this embodiment, high-strength polyester filament is selected. High-strength polyester filament has high strength and can increase the strength of the easily dyeable polyester core-spun yarn, thereby also improving the strength of the easily dyeable polyester fabric 1.
[0022] Furthermore, the antibacterial, skin-friendly fabric layer 2 is woven from an antibacterial, skin-friendly core-spun yarn, which includes an antibacterial core yarn and cotton fibers wrapped around the antibacterial core yarn. The antibacterial core yarn provides antibacterial properties, while the cotton fibers make the fabric skin-friendly when in contact with the human body, thereby improving the wearing comfort of clothing made from the fabric.
[0023] Furthermore, the antimicrobial core yarn is a nano-zinc oxide-modified polyester low-elasticity network yarn; the surface of the cotton fibers is coated with an antimicrobial agent, ensuring that all fibers used in the antimicrobial, skin-friendly core yarn possess antimicrobial properties, thereby enhancing the overall antimicrobial efficacy of the antimicrobial, skin-friendly fabric layer 2. The antimicrobial agent coated on the cotton fiber surface is a nano-zinc oxide antimicrobial agent. Unlike silver ion antimicrobial agents, which are heavy metals, zinc, as a metal element essential to the human body, can prevent harm to the body.
[0024] Example 2
[0025] Combine Figure 2 This embodiment is described in detail. The easily dyeable polyester composite fabric of this embodiment differs from the first embodiment in that a hollow fabric layer 3 is interposed between the easily dyeable polyester fabric layer 1 and the antibacterial, skin-friendly fabric layer 2. This hollow fabric layer 3 is constructed from hollow, warm yarns, interwoven as warp and weft, consisting of parallel-twisted hollow polyester fiber yarns and aerogel fiber yarns. The hollow fabric layer 3 provides excellent thermal insulation, making this composite fabric suitable for use in cooler seasons, such as spring and autumn.
[0026] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
