Technical Field

The utility model relates to the technical field of textile fabrics, in particular to a high-density waterproof polyester fabric.

Background Art

Polyester is a synthetic fiber, also known as polyester fiber. It is made of a composite of polyethylene terephthalate and polyethylene glycol. Polyester fabrics have been widely used in clothing, home textiles and industrial products. Polyester fabrics have good wrinkle resistance, are not easy to deform and are wear-resistant. They are low in cost and have been widely used in clothing, home textiles and industrial products. High-density polyester fabrics have high yarn density, are waterproof and windproof, and are often used in clothing outerwear. However, polyester has poor thermal insulation properties. Even if the yarn density is increased, it still cannot prevent the loss of heat. Therefore, the thermal insulation performance of high-density polyester fabrics is relatively poor, which needs to be improved.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

Embodiment 1:

As shown in FIG1 , a high-density waterproof polyester fabric comprises: a surface layer 1, a middle layer 2, an inner layer 3 and an inner layer 4. The middle layer 2 is arranged on one side of the surface layer 1, the inner layer 3 is arranged on a side of the middle layer 2 away from the surface layer 1, and the inner layer 4 is arranged on a side of the inner layer 3 away from the middle layer 2.

The surface layer 1 is interwoven with warp yarns and weft yarns, both of which are polyester fiber yarns, and the density of the warp yarns is 95-105 yarns/cm, and the density of the weft yarns is 85-95 yarns/cm. In this embodiment, the density of the warp yarns is 100 yarns/cm, and the density of the weft yarns is 90 yarns/cm.

The middle layer 2 is an aerogel thermal insulation layer, which is light and warm.

The inner layer 3 is interwoven with warp yarns and weft yarns, and both the warp yarns and the weft yarns are thermal insulation composite yarns. As shown in FIG2 , the thermal insulation composite yarn includes a core yarn and a wrapping yarn spirally wound around the outside of the core yarn; the core yarn is a first core-wrapped yarn, the core yarn of the first core-wrapped yarn is a nylon filament 11, and the wrapping yarn is an acrylic fiber yarn 12; the wrapping yarn is a hollow polyester fiber yarn 13. The nylon filament 11 has high strength and a strong texture, which can improve the strength of the fabric. Acrylic fiber is fluffy and warm, which can improve the warmth of the fabric. The hollow polyester fiber yarn 13 is spun from hollow polyester fibers, which can improve the warmth of the fabric and protect the acrylic fiber yarn 12 inside.

The inner layer 4 is a polyester polar fleece knitted fabric layer, which has excellent warmth retention and comfortable hand feel. It improves the hand feel of the inner side of the fabric while improving the warmth retention of the fabric, making the clothing made of the fabric more comfortable to wear.

Preferably, the polyester fiber yarn of the surface layer 1 is an antibacterial polyester fiber yarn, and the polyester fiber yarn is also a fluorescent polyester fiber yarn. The antibacterial polyester fiber yarn makes the surface layer 1 less likely to breed bacteria, making it safer to wear; the fluorescent polyester fiber yarn has a luminous effect, which improves the decorativeness of the fabric. Specifically, the preparation steps of the polyester fiber yarn include: melt spinning of fluorescent masterbatch mixed with polyester chips, and then performing antibacterial finishing on the obtained fluorescent polyester fiber yarn to obtain the antibacterial fluorescent polyester fiber yarn.

Embodiment 2:

As shown in FIG2 , based on the first embodiment, a hydrophobic coating is applied to the surface of the surface layer 1 away from the middle layer 2; a PTFE film layer 5 and a polyester mesh layer 6 are arranged between the surface layer 1 and the middle layer 2. The PTFE film layer 6 is arranged on the side of the polyester mesh layer 6 away from the middle layer 2.

The hydrophobic coating makes the surface layer 1 of the fabric hydrophobic, making it difficult to be contaminated by liquids, which is beneficial to improving the waterproofness of the fabric.

The PTFE film layer 5 has waterproof and breathable properties, and can improve the waterproof performance of the fabric.

The polyester mesh fabric layer 6 is made of polyester fibers, which can improve the strength of the fabric and also protect the aerogel middle layer 2 .
