Description

Technical Field

[0001] The invention relates to the field of clothing linings, in particular to a heat-storing, moisture-proof and lightweight down lining. Background Art

[0002] The lining of down jackets is a must-have material. Its main function is to prevent down from penetrating. Consumers are now increasingly demanding the experience (touch) and warmth performance of down jackets, and ultra-thin and lightweight down jacket linings are gaining more and more attention. Currently, down jacket linings are generally made of polyester fibers with low moisture regain, which can prevent down from getting damp to a certain extent and protect the fluffiness of down, so as to achieve the basic performance of down jackets in terms of heat insulation and warmth retention.

[0003] However, in snowy and rainy outdoor environments, the lining cannot effectively resist the continuous erosion of moisture and reduce the chance of down getting damp. At the same time, after getting damp, the down cannot automatically restore its fluffiness, and its warmth retention is significantly reduced; after washing the down jacket, the lining will also slow down the drying speed of the down, which can easily cause the down protein to become rancid, breed bacteria and produce odor. Summary of the invention

[0004] In order to solve the problems existing in the above-mentioned existing down bladder cloths, the present invention provides a heat-storing, moisture-proof and lightweight down bladder cloth, which effectively solves the problem that down is difficult to dry after being damp.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a heat-storage, moisture-proof and lightweight down liner cloth, the liner cloth is formed by interweaving warp yarns and weft yarns one above and one below; the warp yarns are woven by interlacing two materials, light heat-storage yarns and graphene yarns, and the weft yarns are woven by light heat-storage yarns; the warp and weft density of the liner cloth is 925*710T / 10cm; the light heat-storage yarns are 20D / 24F polyester semi-bright filaments, and the graphene yarns are 20D / 24F nylon semi-bright filaments.

[0006] The graphene yarn is one of graphene oxide and amino-modified graphene or a combination of graphene, graphene oxide and amino-modified graphene.

[0007] The light heat storage yarns and graphene yarns in the warp yarns are arranged in a ratio of 1 to 11:1 and are interwoven with the weft yarns.

[0008] The preparation steps of the heat-storage moisture-proof lightweight down liner fabric are as follows: S1: Preparation of 20D / 24F polyester semi-bright filament light thermal storage yarn and 20D / 24F nylon semi-bright filament graphene yarn; S2: Warping, the warp yarn is made of 20D / 24F polyester semi-bright long mercerized light thermal storage yarn and 20D / 24F nylon semi-bright long filament graphene yarn, which are cross-arranged and drawn in a ratio of 1 to 11:1, and the weft yarn is made of 20D / 24F polyester semi-bright long mercerized light thermal storage yarn; S3: Sizing, using a sizing machine to sizing the warp and weft yarns with high pressure using esterified starch as sizing material; S4: weaving, using a shuttle loom to weave the sized warp yarns and weft yarns in a plain weave to obtain a grey cloth; S5: The grey cloth is pre-shaped using a shaping machine and clean water; the shaping temperature is 180-210°C; the shaping speed is 24-30m / min; the rolling pressure is 20-30 pounds; the liquid carrying rate is 75-80%; the warp and weft density of the fabric after shaping is 925*710T / 10cm.

[0009] The preparation steps of the graphene yarn are as follows: adding a certain concentration of graphene dispersion and yarn-making particles into a twin-screw extruder for mixing to obtain a miscible material, and making the graphene dispersion mixed and homogenized into the miscible material during heating; then mixing and extruding the yarn raw material through an extruder, and then drawing the yarn raw material into a graphene yarn through a yarn drawing machine.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the heat-storing, moisture-proof and lightweight down liner fabric adopts photothermal storage yarn compounded with graphene yarn, strengthens the material's spectral absorption and heat storage effect, and the spectral wave frequency spans the three core energy bands of far infrared light, visible light and ultraviolet light from 210nm-1000nm, and has a significant effect on absorbing far infrared heat emitted by the human body, far infrared light emitted by the sun, visible light and part of ultraviolet light, and matches the heating wave frequency of sunlight, thereby enhancing the effect of heat storage and heat reflection. At the same time, in addition to strengthening the heat storage effect, the added graphene yarn can also effectively prevent the down from becoming rancid, breeding bacteria and producing odor, thereby ensuring that the down jacket has a highly clean dressing experience.

[0013] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] This embodiment provides a heat-storing, moisture-proof, lightweight down lining fabric. Figure 1 In the figure, the vertical grid represents the warp, the first horizontal grid represents the first weft, the second horizontal grid represents the second weft, the black square represents the weaving point where the warp and weft one are interwoven, and X represents the weaving point where the warp and weft two are interwoven; the bladder cloth is formed by interweaving the warp yarn and the weft yarn one above and one below; the warp yarn is woven by interlacing two materials, light heat storage yarn and graphene yarn, and the weft yarn is woven by light heat storage yarn; the warp and weft density of the bladder cloth is 925*710T / 10cm; the light heat storage yarn is 20D / 24F polyester semi-bright filament, and the graphene yarn is 20D / 24F nylon semi-bright filament.

[0015] The graphene yarn is one of graphene oxide and amino-modified graphene or a combination of graphene, graphene oxide and amino-modified graphene.

[0016] The light-heat-storage yarns and graphene yarns in the warp yarns are arranged in a 6:1 ratio and are interwoven with the weft yarns.

[0017] The preparation steps of the heat-storage moisture-proof lightweight down liner fabric are as follows: S1: Preparation of 20D / 24F polyester semi-bright filament light thermal storage yarn and 20D / 24F nylon semi-bright filament graphene yarn; S2: Warping, the warp yarn is made of 20D / 24F polyester semi-bright long mercerized light thermal storage yarn and 20D / 24F nylon semi-bright long filament graphene yarn, which are cross-arranged and drawn in a ratio of 6:1, and the weft yarn is made of 20D / 24F polyester semi-bright long mercerized light thermal storage yarn; S3: Sizing, using a sizing machine to sizing the warp and weft yarns with high pressure using esterified starch as sizing material; S4: weaving, using a shuttle loom to weave the sized warp yarns and weft yarns in a plain weave to obtain a grey cloth; S5: The grey cloth is pre-shaped using a shaping machine and clean water; the shaping temperature is 190°C; the shaping speed is 26m / min; the rolling pressure is 25 pounds; the liquid carrying rate is 78%; the warp and weft density of the fabric after shaping is 925*710T / 10cm.

[0018] After testing the finished bile cloth, the results are as follows:

[0019] Through experiments, it was found that the bile cloth has a significant far-infrared temperature rise effect, a far-infrared emissivity of more than 90%, a significant sterilization effect, and compared with conventional bile cloth, the drying time is saved by half.

[0020] The principle of this heat-storage, moisture-proof, lightweight down liner fabric is: using photothermal yarn compounded with graphene yarn, through the screening of minerals that do not pass light frequencies and have good heat absorption and heat storage effects, sub-nanoscale grinding, organic treatment, reasonable matching of their proportions, through the hot melting effect, adding them to the fiber to prepare photothermal fiber, thereby enhancing the spectral heat storage effect of the fabric, and the far-infrared temperature rise of 2-3 degrees. At the same time, after the minerals are organically treated, the emission surface is significantly increased, the emission heat effect is more sustainable, the reflected heat is more, and the emissivity is as high as 93%, which has a more significant baking effect on the down, thereby preventing the down from getting damp and strengthening the drying of the down; at the same time, graphene yarn is also one of the excellent materials for photothermal storage, which has the effect of strengthening the reflected heat effect.

[0021] In this embodiment, the light heat storage yarn has a certain antibacterial and antimicrobial effect. In order to prevent the problem of rancidity of down and feathers producing odor, graphene yarn is added for strong assistance. Both the light heat storage yarn and the graphene yarn are contact-type sterilization yarns, which can perform strong physical cutting and sterilization on the breeding microorganisms. By penetrating the cell wall of bacteria and destroying the cell membrane, the transmission of bacterial film-forming substances is prevented, and the breathing and electron transmission systems are blocked to achieve the purpose of killing bacteria, thereby effectively inhibiting bacteria from decomposing organic substances to produce odors, such as H2S, SO2, thiols, etc. The addition of organic titanium dioxide can enhance its effectiveness. It fundamentally cuts off the rancidity of down (protein) and prevents the down from getting damp and producing odor.
