Description

Technical Field

[0001] The utility model relates to the technical field of down jackets, and more particularly to a water-repellent and warm down jacket. Background Art

[0002] Water-repellent down jackets are usually made by chemically treating the surface of natural down to form a hydrophobic film. This treatment gives the down a certain water repellency and can resist the invasion of water vapor for a period of time. This special treatment allows the down to quickly repel moisture and stay dry when it encounters moisture.

[0003] Chinese patent (202120029210.9) discloses a waterproof and breathable down jacket, wherein the clothing body (1) comprises an inner layer (8), an outer layer (3) and a filler arranged between the inner layer (8) and the outer layer (3), the outer layer comprises a base layer (4), a breathable layer (5) arranged outside the base layer (4) and a waterproof layer (6) arranged outside the breathable layer (5), the base layer (4) is a polyester-cotton blended layer, the breathable layer (5) is woven from polyester fiber and bamboo charcoal fiber, and the waterproof layer (6) is a polytetrafluoroethylene film provided with a plurality of breathable holes (7). It is not reasonable for the patent to design the waterproof layer at the outermost side. Although it can play a waterproof role, the water repellency is poor. When encountering relatively humid weather, the surface of the down jacket will be relatively humid. Due to the long-term adhesion of water vapor to the waterproof layer, the breathability becomes poor. If the down jacket is wet for a long time, it will not only affect the wearing comfort, but also the inside of the down jacket will be damp and affect the warmth retention. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme 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. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, this embodiment provides a water-repellent and warm down jacket, including a clothing body, wherein the clothing body includes an outer layer 1, an inner layer 2 and a filler 3 arranged between the inner layer 2 and the outer layer 1, and a grid-like space is formed between the outer layer 1 and the inner layer 2 by sewing or hot pressing bonding, and the space is used to add the filler 3, and the filler 3 is duck down or goose down.

[0029] The outer layer 1 includes an outer base layer 4 and an inner base layer 5; the outer base layer 4 is a nylon layer, and the inner base layer 5 is a polyester fiber layer. The composite structure of the nylon layer and the polyester fiber layer has better comprehensive performance than a single layer of nylon or polyester fiber material, and can provide better wear resistance, air permeability, wrinkle resistance, shape retention, lightness and comfort.

[0030] A water-repellent coating 6 is provided on the outside of the outer base layer 4, and a hydrophobic layer 7 is provided on the outer layer 1 of the water-repellent coating 6; the water-repellent coating 6 is a DWR coating; the hydrophobic layer 7 is a nano-hydrophobic layer 7; the DWR coating increases the surface tension of the fabric so that water can form water droplets on the surface of the clothing and roll off easily, thereby keeping the clothing dry and increasing the water repellency and anti-wetting properties of the fabric; the nano-hydrophobic layer 7 has excellent anti-fouling, water-repellent and self-cleaning properties; in addition, by forming extremely small protrusions on the surface of the DWR coating, the contact area between the water droplets and the surface is reduced, the flow rate of water is increased, and it helps the water to slide off the surface of the DWR coating faster, thereby cooperating with the DWR coating to increase the overall water repellency; the DWR coating will adhere to dirt after a period of use, but by designing the nano-hydrophobic layer 7, dirt is not easily formed on the DWR coating, thereby ensuring the water repellency and extending the service life of the DWR coating.

[0031] An outer waterproof layer 8 is provided inside the outer base layer 4, an inner base layer 5 is provided inside the outer waterproof layer 8, and an inner waterproof layer 9 is provided inside the inner base layer 5. The outer waterproof layer 8 is a polytetrafluoroethylene film; the inner waterproof layer 9 is a microporous waterproof membrane. By combining the polytetrafluoroethylene film and the microporous waterproof membrane, the advantages of both can be obtained. In addition, the polytetrafluoroethylene film is designed on the outside to fully utilize its weather resistance and protective performance, while the microporous waterproof membrane is designed on the inside to exert its waterproof, breathable and filtering functions. Such a combination can ensure waterproof and anti-fouling while also ensuring the comfort of the wearer and the versatility of the clothing.

[0032] The inner layer 2 includes a skin-friendly layer 10 , an antibacterial layer 11 disposed outside the skin-friendly layer 10 , and a moisture-proof isolation layer 12 disposed outside the antibacterial layer 11 .

[0033] The moisture-proof isolation layer 12 is a TPU or PVC film; TPU or PVC film itself has good waterproof performance. As an isolation layer, they can prevent moisture from penetrating into the down layer, keeping the down dry and warm; in addition, they can effectively prevent the down from escaping through the gaps in the fabric, keeping the clothing clean and warm.

[0034] The antibacterial layer 11 is a bamboo charcoal fiber layer. The bamboo charcoal fiber layer can not only provide good antibacterial and antibacterial effects, but also bring a comfortable wearing experience, and meet the needs of modern consumers for environmental protection and health.

[0035] The skin-friendly layer 10 is a Tencel and cuprammonia fiber blended layer. As the skin-friendly layer 10 of the down jacket, the Tencel and cuprammonia fiber blended layer has good softness, air permeability, moisture absorption, elasticity and comfort, which can not only provide a comfortable wearing experience, but also bring dual benefits of health and environmental protection.
