Description

Technical Field

[0001] This utility model relates to a fabric, specifically a down-proof down jacket fabric. Background Technology

[0002] Down jackets, known for their lightness, warmth, and comfort, have always been favored by consumers. With rising living standards, down jackets are no longer just winter clothing; they've become increasingly fashionable, and people's demands for them are also rising. Down is an animal protein fiber with millions of tiny triangular pores densely packed on its spherical fibers. These pores expand and contract with temperature changes, providing a temperature-regulating function. They absorb heat from the body and insulate against cold air. Down jackets require several sections between the inner and outer layers of fabric to lock in the down. A common method is quilting, but quilting threads are prone to pinholes, leading to down leakage. This down leakage problem severely impacts the aesthetics and comfort of down jackets; therefore, it is necessary to provide a down-proof fabric. Utility Model Content

[0003] The purpose of this invention is to provide a down-proof down jacket fabric that has the function of preventing down leakage while also having a good warmth retention effect.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a down-proof down jacket fabric, comprising: an inner layer and an outer layer, wherein an down-proof layer is disposed between the inner layer and the outer layer; the down-proof layer is composed of two or more tubular fabrics evenly distributed side by side; the down-proof layer is connected to the inner layer and the outer layer by dot-matrix hot-melt PU adhesive; the inner layer is woven from antibacterial and warm yarns; the outer layer includes a warm layer; the warm layer is woven from hollow polyester filaments.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the tubular fabric is a 20D double-layer quilt-free nylon tubular fabric.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial and warm yarn is a modal acrylic fiber blended antibacterial yarn.

[0007] Based on the above solution and as a preferred embodiment of the above solution: the outer layer further includes a wear-resistant layer, which is disposed on the side of the insulation layer away from the down-proof layer.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the wear-resistant layer is made of nylon filaments interwoven together, the nylon filaments having a specification of 70D / 72F and a twist of 680 twists / m.

[0009] The beneficial effects of this utility model are as follows: Based on the down-proof down jacket fabric of this utility model, the down-proof layer avoids the down leakage problem caused by the traditional quilting method of separating down through the parallel tubular fabric. The insulation layer can contain a large amount of still air to form a unique insulation system, which has excellent properties such as warmth, light weight and fluffiness. The inner layer is made of antibacterial and warm yarn, which has the functions of warmth, comfort and antibacterial and bacteriostatic functions. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] Combination Figure 1-2 This embodiment provides a detailed description of a down-proof down jacket fabric, comprising: an inner layer 1 and an outer layer 2, wherein a down-proof layer 3 is disposed between the inner layer 1 and the outer layer 2; the down-proof layer 3 is composed of two or more tubular fabrics arranged side by side and evenly distributed; the down-proof layer 3 is connected to the inner layer 1 and the outer layer 2 by dot-matrix hot-melt PU adhesive; the inner layer 1 is woven from antibacterial and heat-insulating yarns; the outer layer 2 includes a heat-insulating layer 4; the heat-insulating layer 4 is woven from hollow polyester filaments.

[0017] Specifically, the specification of hollow polyester filament is 16.5 tex / 144f. The hollow structure of hollow polyester filament can reduce the weight of the fiber by 20% compared with ordinary fibers, and can contain a large amount of still air to form a unique insulation system. It also makes the fiber aggregate more fluffy, so that the fabric is lightweight while its warmth performance is 65% higher than that of ordinary fabrics of the same material. It has excellent properties such as warmth, lightness and fluffiness.

[0018] Furthermore, the tubular fabric is a 20D double-layer quilt-free nylon tubular fabric. Specifically, after the tubular fabric is filled with down, adjacent tubular fabrics come into contact sideways due to expansion. The cross-sectional perimeter of the 20D double-layer quilt-free nylon tubular fabric is 15cm. Two rows of dotted hot-melt PU adhesive are evenly distributed on both sides of the tubular fabric, connecting it to the inner layer 1 and the outer layer 2 respectively. However, there is no dotted hot-melt PU adhesive between adjacent tubular fabrics. This arrangement ensures that the down-proof layer 3 is located between the inner layer 1 and the outer layer 2 without affecting the down filling process inside the tubular fabric. The tubular fabric binds the down inside, and adjacent tubular fabrics do not need to be sewn together. Compared with traditional fabrics that are filled with down and then quilted, this prevents down from escaping through the gaps in the quilting lines. In addition, the inner layer 1 and outer layer 2 are also provided on both sides of the tubular fabric to further prevent down from escaping.

[0019] Furthermore, the antibacterial and warm yarn is a modal acrylic fiber blended antibacterial yarn. Specifically, the modal acrylic fiber blended antibacterial yarn is a 40 / 30 / 30, 14.8tex blended yarn of modal / acrylic / indigo fiber.

[0020] Modal fiber combines the advantages of both natural and synthetic fibers, possessing the softness of cotton, the luster of silk, and the smoothness of linen. Its water absorption and breathability are superior to cotton, and it also exhibits good strength and elongation. Acrylic fiber is characterized by its fluffiness, good elasticity, warmth, and soft hand feel. Indigo leaf fiber is produced using a blending spinning method that incorporates an antibacterial extract solution of the natural Indigo leaf as an antibacterial agent into the spinning solution, following the viscose fiber production process. Therefore, modal acrylic Indigo leaf fiber blended antibacterial yarn possesses natural antibacterial properties while also providing comfort and warmth.

[0021] Example 2

[0022] Combination Figure 3 This embodiment will be described in detail. Based on Embodiment 1, the outer layer 2 further includes a wear-resistant layer 5, which is disposed on the side of the insulating layer 4 away from the down-proof layer 3. Specifically, the wear-resistant layer and the insulating layer are bonded together using a dot-matrix hot-melt PU adhesive.

[0023] Furthermore, the wear-resistant layer 5 is made of interwoven nylon filaments, the nylon filaments being 70D / 72F with a twist of 680 twists / m.

[0024] As the layer in contact with the outside of the down jacket fabric, the abrasion-resistant layer 5 needs to have functions such as abrasion resistance and scratch resistance, and is usually made of fabric with low thermal conductivity. Nylon filament has a low thermal conductivity coefficient, high strength, and good abrasion resistance. After proper twisting, the abrasion-resistant layer 5 woven from it is not easy to snag when encountering scratches and friction, thus improving its abrasion resistance.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
