Description

Technical Field

[0001] The invention relates to a running type warm down jacket with excellent wrapping performance. Background Art

[0002] The running down jackets currently on the market mainly adopt the following solutions:

[0003] (1) Choose a lightweight down solution. The lining layer is made of nylon or polyester below 20D, mostly plain weave, with a small amount of plaid, warp and weft density of 400-450T, and then matched with anti-down calendering, with a gram weight of 45g / m 2 The middle part is filled with less than 100g of high-loft down with a down content of 90%, which can achieve lightness, warmth, breathability and skin-friendly. The disadvantage is that it is non-elastic and uses a line process, and the overall wrapping is not good. When wearing and running, the clothes will bulge more or less due to the influence of wind or forward running speed, and the pinholes at the lines will cause rapid heat loss and the warmth retention will also decrease.

[0004] (2) Select seamless hot-pressed lightweight down, woven with 20-40D polyester in plain weave, with a warp and weft density of 400-450T. First, glue the pattern on the reverse side of one layer of fabric, and then stick it to the reverse side of another layer of fabric and press it at high temperature to obtain a hot-pressed double-layer fabric with a gram weight of 100-130g / m 2 After layout, cutting and filling with down with 90% down content, you can get seamless hot-pressed thin down, which can be lightweight, warm, breathable, skin-friendly and stylish. The disadvantage is that it is not elastic and can only be made of polyester. The seamless hot-pressing fastness of nylon material is poor, and the seams will pop when filling and washing.

[0005] (3) Seamless woven thin down fabric, using 20-40D polyester, woven into double-layer plain weave, after dyeing and finishing, the single-layer warp and weft density is 400-450T, and the gram weight is 110-140g / m 2 After layout, cutting and filling with down with 90% down content, you can get a seamless woven thin down fabric, which is lightweight, warm, breathable, skin-friendly and stylish. The disadvantage is that it is not elastic and expensive. It is limited by the inevitable instability of weaving and dyeing, which will cause large fluctuations in down-proof properties.

[0042] In order to further explain the technical solution of the present invention, it is described in detail below in conjunction with embodiments.

[0043] Reference Figures 1 to 5A running-type warm down jacket with excellent wrapping performance comprises a down jacket body 10, wherein the down jacket body 10 comprises a main fabric area 40 and a spliced ​​fabric area 20 which are spliced ​​together (specifically, they can be sewn), the spliced ​​fabric area 20 comprises a front waist area, a back waist area, a left waist area, a right waist area, a left arm area, a right arm area, a left sleeve area and a right sleeve area which are respectively arranged corresponding to the front waist, the back waist, the left waist, the right waist, the inner side of the left arm, the inner side of the right arm, the left wrist and the right wrist of the human body, the main fabric area 40 is spliced ​​by a first fabric, and the first fabric comprises a first surface layer 401 woven by polyester yarn, a first inner layer 402 woven by polyester yarn and a down layer 403 arranged between the first surface layer 401 and the first inner layer 402. The spliced ​​fabric area 20 is formed by splicing the second fabric, and the second fabric includes a second surface layer 201 and a second inner layer 202 that are composited together. The second surface layer 201 is a nylon fabric layer, and the second inner layer 202 is a polar fleece fabric.

[0044] In terms of material selection, nylon is skin-friendly, lightweight, wear-resistant, and moisture-absorbent. Its thermal conductivity is as high as 0.244W / (m·K). It has a good cool feeling when touched. Wearing it close to the skin in winter will produce a cool feeling. It also has poor quick-drying properties. When sweating while running in winter, it will stick to the skin, and the wearing experience is not dry. Polyester is crisp, stylish, and quick-drying. Its thermal conductivity is as low as 0.084W / (m·K). It does not feel cool when touched. Wearing it close to the skin in winter will not produce an uncomfortable cool feeling. It can keep the skin dry when sweating while running in winter. Since running down jackets are worn with long T-shirts, short T-shirts, vests, or directly close to the skin, the wearing temperature is generally minus 10℃ to 10℃. The weather is cold and sweating is high. The fabric is required to have no cool feeling when touched and good quick-drying and breathability. Therefore, it is more appropriate to choose polyester material.

[0045] As a preferred embodiment of the present invention, the first surface layer 401 is woven from 25D / 72F polyester in a plain weave, and the first inner layer 402 is woven from 25D / 72F polyester in a plain weave. The polyester is semi-bright polyester, and the spinning method is DTY, which is a stretched textured yarn that curls like a spring, giving the fabric good shape retention and ductility, as well as the fluffiness of the textured yarn; the yarn gloss is semi-bright, giving the fabric a natural luster, which is more beautiful and durable; the Denier number is as low as 25D, and the F number is as high as 72F, giving the fabric a soft feel and excellent skin-friendliness. In the embodiment, the warp density of the first surface layer 401 and the first inner layer 402 is 230 strands / inch, and the weft density is 185 strands / inch, ensuring that the fabric has a soft feel and good anti-velvet properties.

[0046] As a preferred embodiment of the present invention, the first surface layer 401 and the first inner layer 402 are hot-pressed together by pattern glue 405 to form a plurality of pattern pressing grooves 45. The pattern glue 405 is discontinuous. The cycle length and spacing maximize the filling area, that is, maximize the warmth retention, while ensuring that the down does not flow to one place and the filling is easy. After multiple evaluations, the gluing width, that is, the pattern glue 405, is most suitable to be 6 cm. When the main fabric area 40 is filled with down to make a running down jacket, it has good wrapping properties for the body, and can be lightweight, breathable, skin-friendly, stylish, and down-proof.

[0047] As a preferred embodiment of the present invention, the second surface layer 201 is woven by warp knitting with a covering yarn, and the covering yarn is 40D / 12F nylon covering 40D spandex. In the embodiment, the weight ratio of nylon in the covering yarn is 78.6%, and the spandex is 21.4%. Among them, nylon adopts FDY, which is a fully stretched yarn with high crystallinity and orientation, giving the fabric a smooth and soft feel and good skin-friendliness; the yarn adopts semi-gloss, giving the fabric a natural luster, which is more beautiful and durable; the polyester denier number is not too high or too low, and the F number is very small, ensuring good shape retention and soft feel; the spandex has good elasticity to ensure free movement.

[0048] In the present invention, the second inner layer 202 is woven by 75D / 144F polyester stretched textured yarn and 75D / 36F polyester stretched textured yarn in a weft knitting manner. After weaving, the fleece fabric is formed by shaping, brushing, combing, shearing, and polarizing. Among them, the polyester spinning method is DTY, that is, stretched textured yarn, which curls like a spring, giving the fabric good shape retention and ductility, as well as the fluffiness of the textured yarn; the yarn gloss adopts semi-gloss, giving the fabric a natural luster, which is more beautiful and durable; the polyester denier number is not too high or too low, and the F number is relatively high, ensuring good shape retention and soft feel.

[0049] As a preferred embodiment of the present invention, the second surface layer 201 and the second inner layer 202 are compounded together by a plurality of TPU glue dots 203, and the area of ​​the glue dots 203 accounts for 40% of the area of ​​the compound surface of the second surface layer 201 and the second inner layer 202, which not only ensures the adhesion strength and does not fall off or bubble during wearing and washing, but also ensures that the hand feel is soft and breathable. The composite material turns the double layer into a single layer, which is more crisp and stylish, and has excellent elasticity. The polar particles are soft and close to the body as the inner layer, and the running clothes made of it have excellent wrapping properties, which can perfectly solve the problem of clothes bulging when running, and are warm, lightweight, skin-friendly and breathable.

[0050] The D in the present invention is called the denier number in the industry, which refers to the weight of 9000 meters of yarn (in grams). The F in the present invention refers to the number of microfibers in a yarn.

[0051] As a preferred embodiment of the present invention, the left waist region extends upward to the corresponding left armpit area of ​​the human body, and the right waist region extends upward to the corresponding right armpit area of ​​the human body.

[0052] As a preferred embodiment of the present invention, the front waist region is composed of a front waist piece 21, which extends from the lower end of the down jacket body 10 to the corresponding abdomen of the human body, and the front waist piece 21 includes a left front waist piece 211 and a right front waist piece 212 symmetrically arranged, the back waist region is composed of a back waist piece 24 arranged corresponding to the front waist piece 21, the left waist region is composed of a left waist piece 22, and the right waist region is composed of a right waist piece 23 corresponding to the left waist piece 22. The left arm region is composed of a left arm inner side piece 31, the right arm region is composed of a right arm inner side piece 32 corresponding to the left arm inner side piece 31, the left sleeve region is composed of a left sleeve piece 33, and the right sleeve region is composed of a right sleeve piece 34 corresponding to the left sleeve piece 33. The main fabric area 40 is composed of a main front piece 41, a main back piece 44, a left arm outer piece 42, a right arm outer piece 43 and a collar piece 50. The left arm inner piece 31 and the left arm outer piece 42 form a left arm tube corresponding to the human arm, and the right arm inner piece 32 and the right arm outer piece 43 form a right arm tube corresponding to the human arm. The main front piece 41 includes a left main front piece 411 and a right main front piece 412. The left main front piece 411 and the left front waist piece 211 are spliced ​​into a left front piece, and the right main front piece 412 and the right front waist piece 212 are spliced ​​into a right front piece. The left front piece and the right front piece are connected together by a zipper 60, and the back waist piece 24 and the main back piece 44 are spliced ​​into a back piece.

[0053] As a preferred embodiment of the present invention, the weight of the down jacket body 10 is 290 g.

[0054] The applicant has conducted a detailed study on the motion state of a running down jacket. First, when running, both arms swing back and forth periodically with a large amplitude, and the elbow joints move frequently, which requires excellent elasticity to ensure free movement.

[0055] Secondly, when running, the arms swing back and forth periodically with a large amplitude, and the inner sides of the arms and the armpits are prone to repeated friction. The clothing areas corresponding to the inner sides of the arms and the armpits must have excellent wrapping properties, without pulling during exercise. The armpits are where heat needs to be dissipated when sweating during running, so good breathability is required. At the same time, affected by wind and forward running speed, the clothes will bulge when running. To solve this problem, the hem of the clothes must have excellent wrapping properties.

[0056] Then, when running, the body leans forward, the outside of the arm and the front chest are the windward side and should have excellent warmth retention, and the back of the vest is the heat-generating area and should have excellent warmth retention.

[0057] Finally, affected by the wind and running speed, the clothes will bulge while running. In order to solve this problem more perfectly, the front chest area and the back vest area must also have excellent shape retention and a good slimming effect.

[0058] To sum up, a down jacket suitable for winter running needs to have excellent warmth retention and a good slimming effect on the outside of the arm, the front chest and the back, excellent elasticity on the elbows, good breathability on the armpits, and excellent wrapping properties on the inside of the arm, the armpits and the hem (i.e., the waist position involved in the present invention). It is difficult to achieve these requirements by using only one kind of fabric, so a scientific and reasonable splicing process is needed to meet these requirements.

[0059] First, the outer side of the arm, the heart of the chest and the back are made of 25D double-layer seamless heat-pressed fabric with a gram weight of 100g / m 2 ; The most reasonable discontinuous wave pattern (multiple pattern pressing grooves 45) and 6cm hot pressing width are adopted to ensure the maximization of the filling area, and the filling content is 90% and the high-quality down with a fluffiness of 800 is 46g, which can retain a large amount of air and is seamless, which can greatly reduce the heat loss caused by the pinholes at the lines, and has excellent warmth retention; the double-layer seamless hot-pressed fabric is crisp and stylish, and with a slim fit, it has a good slimming effect; the Denier number used is as low as 25D and the F number is as high as 72F, which obtains a soft feel, and the seamless process is adopted to reduce the lines and alleviate the skin friction caused by the lines, and has good skin-friendliness; the single piece consumption of the double-layer seamless hot-pressed fabric is 1 yard, weighing about 100g, plus 46g down, a total of 146g, which is relatively light; the double-layer seamless hot-pressed fabric has no glue or film, has good air permeability, and is not stuffy when worn.

[0060] Secondly, nylon warp-knitted elastic composite polar fabric is used on the inside of the arm, underarm and hem. The surface layer contains 21.4% spandex, which has excellent elasticity, and the inner layer is polar fabric, which has excellent ductility. The two have excellent elasticity after being combined to ensure free movement of the elbows; there is no membrane in the middle of the composite fabric, and the composite process uses point-sticking, which has good air permeability to ensure good heat dissipation under the armpits; the composite fabric turns the double layer into a single layer, which is more crisp and stylish, and has excellent elasticity. The polar fabric is soft and close-fitting as the inner layer, and the running clothes have excellent wrapping properties, which can perfectly solve the problem of clothes bulging when running; the polar fabric of the composite fabric can retain more air and has good warmth retention; the polar fabric of the composite fabric is soft and close-fitting, and has good skin-friendliness; the composite fabric consumes 0.5 yards per piece and weighs about 140g, which is relatively light.

[0061] The cuff material is made of nylon warp-knitted elastic composite polar fabric. When wrapping the edge, the 2cm wide composite fabric polar fabric is trimmed with scissors, then folded and fixed with seamless hot pressing to ensure that the cuffs are both warm and well wrapped.

[0062] Preferably, the collar (collar piece 50) is made of 150g mercerized velvet (100% polyester fiber). On the one hand, it ensures that the neck is warmer when worn. On the other hand, if the collar piece 50 is made of 25D double-layer seamless hot-pressed fabric, the oil stains of the human body can easily make the collar dirty during wearing, and it looks shiny and ugly. Mercerized velvet is very stain-resistant and can improve this problem a lot. The pocket adopts the zipper 60 pocket process, with a bag eyebrow of appropriate size. After the zipper 60 is pulled up, the slider can be perfectly hidden in the bag eyebrow, with good sealing and concealment. It is not only beautiful, but also has a good windproof and warm-keeping effect. The placket zipper 60 (i.e., the zipper 60 between the left front piece and the right front piece) is equipped with an inner drawer and uses a seamless hot-pressing process. After the zipper 60 is pulled up, the zipper 60 is very closed. It is not only beautiful, but also has a good windproof and warm-keeping effect. In addition, the inner layer of the front piece adopts the added lining pongee (100% polyester fiber, 65g / m 2 ), on the one hand, it ensures that the pocket cloth does not leak out, which is very beautiful, and on the other hand, it increases the thickness of the front piece, which has good warmth retention.

[0063] Finally, the slim fit is adopted in the version to further enhance the wrapping of the running down jacket and have better shape retention.

[0064] The down jacket of the present invention is made by the following method:

[0065] ① Plate making: according to the design style drawing, plate making, marking and printing paper pattern;

[0066] ② Cutting: Cut the first fabric and the second fabric according to the pattern to obtain garment pieces;

[0067] ③ Sewing: sew the filled part of the first fabric all around first and then fill it with down. The weight of the down filled with the left main front piece 411 and the right main front piece 412 is 6g, the weight of the down filled with the main back piece 44 is 13g, the weight of the down filled with the left arm tube and the right arm tube is 7.5g, the weight of the down filled with the collar piece 50 is 6g, and the whole piece is filled with 46g of down; splice the first fabric and the second fabric, open the pockets, close the shoulder seams, install the collar and sleeves, and sew according to the light down process.

[0068] ④Ironing: Since the down jackets are relatively flat, they only need to be lightly steamed to avoid damaging the material properties.

[0069] The relevant test data of the present invention are as follows:

[0070]

[0071] The product form of the present invention is not limited to the embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the present invention.
