Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a down jacket with a twill weave. Background Technology

[0002] Autumn and winter are cold seasons, so the essential requirement for consumers' autumn and winter clothing is warmth. In addition to this, the main factors influencing consumers' purchases are: aesthetic requirements such as novelty, fashion, individuality, and style; comfort requirements such as stretchability, lightweight, warmth, anti-static properties, and breathability; and cost-effectiveness.

[0003] Currently, most down jackets are made of woven fabrics that interweave warp and weft threads. These fabrics offer down-proof, windproof, and breathable properties, with down-proofness being particularly important. There are three main types of down fabrics commonly found on the market:

[0004] (1) Applying a film or coating to the base fabric: The film or coating is used to prevent down leakage. Of course, the primary premise is that it is breathable and does not affect the lightness and softness of the fabric. The film or coating can make the fabric not only waterproof, oil-proof and UV-proof, but also antistatic, moisture-wicking and perspiration-wicking functions. In addition, the environmentally friendly printing and dyeing makes it very comfortable to wear and its functions are even better.

[0005] (2) High-density fabric: Down fabric itself has a high density, generally above 290T. Then, a post-processing technique is used to fuse the surface fabric at high temperature to reduce the gaps in the fabric and improve down-proofness. The resulting fabric is the lightest and softest of all down jacket fabric types, and also has windproof, water-repellent, and breathable properties. Although this method provides excellent warmth, it is generally heavy and has monotonous colors, making it unpopular with consumers.

[0006] (3) Ordinary woven fabric with down-proof fabric: Generally, low-density nylon or polyester is used. When making down jackets, a down-proof fabric is added to the inside of the fabric to prevent down. The down-proof performance is good. The disadvantage is that the down-proof fabric affects the softness of the down jacket and increases the weight of the whole garment; most importantly, if inferior down-proof fabric is used, the breathability of the down jacket will be greatly reduced; and after washing, the down-proof fabric is easy to be damaged or clump together. Another method is to apply down-proof treatment, which involves brushing a layer of down-proof glue onto the inside of the fabric. The fabric has a very poor feel and is not breathable.

[0007] In addition, static electricity is generated during the production of textiles when fibers are stretched, wound, dried, and rub against each other. If measures are not taken in time, it will hinder production. During the wearing process, static electricity generated by friction makes the fabric more likely to attract dust, affecting the comfort of wearing it.

[0008] Chinese Patent Application No. 202320362166.2 discloses a multifunctional down jacket with a PU coating, comprising a down jacket body, sleeves on both sides of the down jacket body, the down jacket body and sleeves connected by a first windproof zipper, a protective hood on the top of the down jacket body, the down jacket body and protective hood connected by a second windproof zipper, a down lining inside the down jacket body, the down jacket body and down lining connected by a first plastic zipper, and a skin-friendly layer at the bottom of the down lining; the first plastic zipper ensures a stable connection between the down jacket body and the down lining, and facilitates disassembly and assembly, making the down jacket easy to wash; the protective layer made of PU-coated fabric increases the product's windproof and waterproof performance; and the skin-friendly layer made of skin-friendly cotton material increases user comfort, making it highly practical. However, this down jacket lacks the appearance of a zigzag stripe and the down-proof function.

[0009] Chinese Patent Application No. 202420354127.2 discloses a UV-resistant and stain-resistant down jacket fabric, comprising a main fabric layer and a second down-proof layer. The main fabric layer has a stain-resistant layer inside, a UV-resistant layer below the stain-resistant layer, a down layer below the UV-resistant layer, a first down-proof layer below the UV-resistant layer, a second down-proof layer below the first down-proof layer, and a lining below the second down-proof layer. This invention improves the stain resistance of the fabric through the combination of the stain-resistant layer, the UV-resistant layer, and the first abrasion-resistant layer, solving the problems of poor stain resistance in existing down jacket fabrics and the difficulty in washing down jackets, which affects the wearing experience. However, the down jacket has two layers of down-proof fabric, which affects the softness of the down and increases the overall weight; moreover, the down-proof fabric is prone to damage or clumping after washing. Summary of the Invention

[0010] Therefore, in view of the above problems, this utility model provides a down jacket with elastic woven fabric, which solves the problems that existing down jackets do not have a serrated diagonal stripe appearance, the fabric color is monotonous, and they cannot have the functions of preventing down leakage and waterproofing.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A woven down jacket includes a jacket body with a three-layer structure, comprising an outer down-proof fabric layer, a middle down layer, and an inner lining layer. The down-proof fabric layer has a zigzag woven fabric on the front and a TPU down-proof breathable membrane on the back. The zigzag woven fabric is woven from warp and weft yarns. The zigzag woven fabric is based on a 2-up-1-1-2-up twill weave to form a zigzag twill weave, and the number of yarns before the twill lines change direction is defined as K.j The K j =9, sawtooth fly number=4, sawtooth number=3; define warp weave repeat number as R j The weft yarn repeat number is R. w The R j =36, the R w =6.

[0013] Wherein, the sawtooth twill weave is a weave in which the peaks of the mountain-shaped twill are aligned on a diagonal line to form a sawtooth pattern; the sawtooth count is the number of yarns between the starting points of two adjacent sawtooths.

[0014] Furthermore, the threading method for the serrated twill weave is the pattern-based threading method.

[0015] Furthermore, the weight of the zigzag woven fabric is 120 g / m². 2 .

[0016] Furthermore, the width of the serrated woven fabric is 140cm.

[0017] Furthermore, both the warp and weft yarns are core-spun yarns made of a blend of nylon and spandex.

[0018] Furthermore, the down layer is grey duck down with a down content of 95%.

[0019] Furthermore, the lining layer is calendered 15D nylon twill.

[0020] Furthermore, the nylon has a specification of 30D.

[0021] Furthermore, the spandex has a specification of 20D.

[0022] Furthermore, the core-spun yarn is semi-dull.

[0023] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0024] 1. The down jacket uses a three-layer structure. The outer layer is a down-proof fabric layer. The front of the outer layer is a serrated woven fabric, and the reverse side is a TPU down-proof and breathable membrane. Therefore, it has the appearance of colorful serrated twill stripes and the functions of windproof and breathable. Compared with regular down jackets, it is lighter and more convenient, softer to the touch, and has excellent warmth retention and anti-static properties. It is fashionable, beautiful and novel, which meets the aesthetic needs of contemporary young consumers.

[0025] 2. The middle down layer uses grey duck down with a down content of 95%. Duck down has the advantages of being fluffy, low in density, and having poor thermal conductivity, which prevents heat loss caused by heat conduction, making the down jacket have excellent warmth retention and be lightweight overall, meeting consumers' winter wear needs.

[0026] 3. The inner lining layer uses calendered 15D nylon fabric, which not only has a bright appearance, but also has functions such as downproof, breathable, moisture-wicking, strong and wear-resistant. It is skin-friendly, comfortable to wear, and meets the needs of consumers.

[0027] 4. Zigzag woven fabric is woven on a loom using a 2-up-1-1-2-up twill weave, creating a regular zigzag appearance. Down jackets made from this fabric can visually rival those coated with glossy glue or laminated with a glossy film, radiating an extremely shiny zigzag sheen. The appearance is novel, fashionable, high-end, and textured, exuding a strong sense of technology. Especially in the current winter when down fabrics are monotonous in color, down jackets with this appearance will be highly favored by consumers.

[0028] 5. The TPU downproof and breathable membrane is combined with the serrated woven fabric to form a downproof and breathable fabric layer, which is waterproof, breathable and moisture-wicking. The finished garment will not feel stuffy when worn, and it has a smooth and delicate feel. There is no need to add downproof lining when making down jackets, which reduces the overall weight of the finished garment, making it lighter and more convenient, and also reduces the cost of the finished garment.

[0046] Graphene oxide-doped modified liquid disperse dyes were used to treat the serrated woven fabric using a high-temperature, high-pressure one-bath method. During the reduction cleaning process, the graphene oxide was reduced, imparting antistatic properties to the fabric. Resistance testing showed that the fabric surface resistivity was 9.8 × 10⁻⁶. 6 Ω, which can achieve a very good antistatic standard and has good antistatic performance; the fastness test of the fabric shows that its abrasion resistance and washing fastness can reach level 4 or above;
