Description

Technical Field

[0001] The utility model relates to a thermal insulation polyester blended fabric, belonging to the technical field of textile fabrics. Background Art

[0002] With the rapid advancement of technology and the continuous improvement of people's living standards, traditional thermal insulation materials such as cotton, wool, and down can no longer meet modern people's demand for multifunctional thermal insulation. Therefore, research on thermal insulation materials for clothing is highly concerned with whether it can overcome the bulky feeling of traditional thermal clothing and make clothing lighter while providing excellent warmth. Two main approaches are being taken to improve the thermal insulation performance of fabrics: first, using fibers with low thermal conductivity whenever possible to manufacture thermal insulation materials. Second, by comprehensively considering conduction, convection, and radiation, the fabric's air content is maximized without moving, i.e., achieving maximum still air content. However, fabrics with excellent thermal insulation properties can also harbor bacteria on the inside. Polyester fiber offers many advantages, but the challenge is to create a thermally insulating blended fabric using polyester that not only provides warmth but also exhibits excellent antibacterial properties.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] Combine Figure 1 、 Figure 2 and Figure 3This embodiment is described in detail. This embodiment involves a thermal insulation polyester blended fabric comprising a surface fabric 1, a thermal insulation fabric layer 2, and a lining fabric 3, all bonded together via a hot melt adhesive film. The surface fabric 1 is made of polyester / Viloft blended yarn woven in a plain weave; specifically, the yarn is a hollow polyester fiber / Viloft 65 / 35 blend with a fineness of 18.45 tex x 2.

[0023] The thermal insulation fabric layer 2 comprises a composite first thermal insulation wadding layer 21, a spacer fabric layer 22, and a second thermal insulation wadding layer 23. The first thermal insulation wadding layer 21 and the second thermal insulation wadding layer 23 are made of hot melt cotton or aerogel fiber nonwoven fabric. In this embodiment, aerogel fiber nonwoven fabric is selected, specifically needle-punched nonwoven fabric.

[0024] Furthermore, the spacer fabric 22 is an aerogel thermal insulation knitted fabric. The thermal insulation fabric layer 22 is formed by stacking the first thermal insulation wadding layer 21, the spacer fabric layer 22 and the second thermal insulation wadding layer 23 and then acupuncturing them together.

[0025] The inner layer fabric 3 is interwoven with antibacterial fiber filaments, which include a fiber filament body 31, a polydopamine layer 32, and a silver-plated layer 33. The fiber filament body 31 in the antibacterial filaments is polyester filament, nylon filament, or aramid filament. In this embodiment, nylon filament is selected. Specifically, the nylon filament is placed in a solution containing dopamine and pulled multiple times, so that polydopamine adheres to the surface of the nylon filament. The nylon filament with the polydopamine layer on the surface is then immersed in a silver ammonia solution for pretreatment for 20 minutes, and then a glucose solution is added for chemical Ag plating. After a certain period of time, the fiber is removed, washed with distilled water, and dried to obtain a nylon filament conductive fiber with a surface coated with an Ag layer. Due to the metallic silver used on the surface, the anti-bacterial inner layer fabric 3 also has an antibacterial effect.

[0026] Example 2

[0027] Combine Figure 4 The present embodiment is a thermal insulation polyester blended fabric, which is different from the first embodiment in that the surface fabric 1 is compounded with a PTFE microporous membrane 4 on the side away from the thermal insulation fabric layer 2.

[0028] The difference from Example 1 is that a planar three-dimensional fabric layer 5 is interposed between the surface fabric layer 1 and the thermal insulation fabric layer 2. This planar three-dimensional fabric 5 is made of three sets of strong core-spun yarns interwoven at a 60° angle. These strong core-spun yarns comprise ultra-high molecular weight polyethylene filaments and polyester hollow fibers wrapped around the ultra-high molecular weight polyethylene filaments. The use of ultra-high molecular weight polyethylene filaments gives this blended fabric excellent cut resistance.

[0029] 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.
