[0002] Down clothes are filled with down flakes, which makes them look like a huge rounded garment; the general amount of duck down accounts for more than half of the down clothes; at the same time, duck down can be mixed with small feathers; it will be cleaned and disinfected at high temperature; after being filled, the garment is a down garment; the warmth of down clothes is the best; they are mainly worn by people in cold regions, but they are also commonly used by polar expedition personnel.
[0003] Among them, the performance of the down jacket fabric directly determines the overall effect of the down jacket, in the user wearing process, plays a vital role, in addition, the down filler is also very important, the filler in the down jacket is the most common is goose down and duck down, down for the three-dimensional structure of down, down is very fluffy compared to other filler materials, so the same weight of down can be fixed more than other materials, a large amount of air. A large number of down filaments are interwoven to retain air and form a protective layer of insulation, thereby achieving good warmth.
[0004] Therefore, the requirements for the fabric of down clothing have been gradually improved, and the fabric of down clothing must have the function of anti-puncture of down and warmth, while taking into account the function of lightness and breathability, so as to reduce the weight of the clothing, and it is easy to wear and wash, but in the prior art, the function of warmth and anti-puncture of down and the function of lightness and breathability are difficult to have at the same time. Content of the invention
[0005] The objective of the present invention is to provide a waterproof, warm and leak-proof luxury down jacket fabric and a preparation method therefor in order to solve the above-mentioned problems.
[0006] The present invention achieves the above-mentioned objective by means of the following technical solutions:
[0007] A waterproof, warm, and fill-leakage-preventing luxury down jacket fabric comprises, in turn from outside to inside, a waterproof layer, a heat-preserving layer (or insulating layer), a breathable layer, and a down-locking layer, said down-locking layer comprising a down-locking fabric made of wool as well as bamboo charcoal fibers.
[0008] The texture of wool is soft and has a good warmth-keeping effect, and a little hot water partially solidifies the protein, resulting in a shrinkage phenomenon, and the placement of bamboo charcoal fibers can effectively alleviate the above-mentioned shrinkage, and at the same time, bamboo charcoal fibers can eliminate odor, release trace elements, be weakly electrically conductive, play an antistatic role, and emit far infrared rays whose wavelengths are suitable for absorption by the human body, accelerate blood circulation and improve the environment inside the human body, through the use of bamboo charcoal fibers and bamboo charcoal fibers.The environment inside the human body, through the enclosing fabric of wool and bamboo charcoal fiber, is comfortable and easy to keep warm with good effect, and can effectively alleviate the shrinkage effect caused by wool.
[0009] Said down-locking fabric is provided with an ellipsoid-shaped concave portion on the inner surface, and the inside of the concave portion is provided with several sets of conical shapes, said down-locking layer is provided with a number of conical shapes; the ultra-fine bamboo charcoal fibers are provided with several groups of ultra-fine bamboo charcoal fibers in a conical structure, said ultra-fine bamboo charcoal fibers being provided with spherical silver nanoparticles inside said ultra-fine bamboo charcoal fibers.
[0010] In other words, the inner surface of said blocking fabric is provided with an ellipsoidal depression portion, the depression portion is uniformly distributed on the inner surface of the blocking fabric, and the ellipsoidal depression portion spatially exists in the long diameter direction and the short diameter direction, which, on the one hand, improves the spatial elasticity of the blocking layer and, on the other hand, when the short diameter direction of the depression portion expands and the momentary release of elasticity, the short diameter direction of the depression portion undergoes rapid reset and relative reset occurs on the surface of the blocking fabric, and relative reset is generated on the surface of the blocking fabric. On the other hand, when the short diameter direction of the hollow part expands and instantly releases the elastic force, the short diameter direction of the hollow part quickly resets and generates a relative elastic force on the surface of the down blocking fabric, which fluffs up the down evenly distributed on the inner surface of the down blocking fabric, so that, by imitating the "principle of bouncing cotton", the down inside the long-lasting down garment is fluffed up to greatly enhance its warmth effect.
[0011] Advantageously, the ultrafine bamboo charcoal fibers are obtained by mechanical splitting of the filament, softening and degumming (or degumming), opening and carding, chemical spinning, twisting at one end, and breaking (or snapping) and cutting to 1 to 2 mm.
[0012] Advantageously, said silver nanoparticles are obtained by using the aqueous phase self-assembly body of a pure hydrophilic random poly copolymer as a template and adding additives consisting of a mixture of nano germanium dioxide and rubber, stirring and by the in situ reduction method, wherein it should be noted that: the silver nanoparticles are treated to form a solution with nano silver ions, and the nano germanium dioxide quickly improves the solution with the nano silver ions with the adsorption force, by adding rubber, on the one hand, the viscous adhesion between the silver nanoparticles and the ultrafine bamboo charcoal fibers between the silver nanoparticles is significantly improved, so as to avoid the loss of silver nanoparticles due to cleaning and friction, on the other hand, the overall ductility of the fluff locking layer is significantly increased,the elasticity of the down lock layer is improved, in addition to the antimicrobial effect of silver nanoparticles. When the template is at low pH, the pure hydrophilic random poly copolymer forms a stable structure of microporous rods and secondary self-assembly rods (spherical or cubic); with the increase of silver reduction rate, the silver nanoparticles disintegrate from spherical or cubic to spherical shape.
[0013] Advantageously, the inside of the ellipsoidal concave portion is provided with a number of groups of ultrafine bamboo charcoal fibers in a conical structure, on the one hand, since the ultrafine bamboo charcoal fibers are provided in a number of groups, a thorn shape is formed by the interlacing between the adjacent ultrafine bamboo charcoal fibers, the root of the fluff is easily attached to the thorn shape, and the fluff is easy to play a blocking role at the ultrafine bamboo charcoal fibers in the thorn shape, which can effectively prevent the fluff located in the inner lining from drifting out. On the other hand, the ultrafine bamboo charcoal fibers contain na spherical silver particles that have a good antibacterial effect and can effectively eliminate the bacteria carried by the down; the overall comfort and antibacterial properties are good; on the other hand, the depressed part corresponds to the following thermal expansion particles. On the other hand, the hollow part corresponds to the following thermal expansion particles. When the thermal expansion particles are subjected to thermal expansion, the hollow part is caused to be in a flat state, at which time the ultrafine bamboo charcoal fibers in the hollow part open inward, facilitating the release of the down at the ultrafine bamboo charcoal fibers, and facilitating the rapid cleaning of the down in the hollow part during cleaning, avoiding the creation of a cleaning dead zone, which results in localized mold.
[0014] Advantageously, said breathable layer comprises a breathable fabric made of ramie fibers and polyester fibers, said breathable fabric is provided with a raised portion on the inner surface of the breathable fabric, and said breathable fabric is provided with thermal expansion particles on the opposing surfaces between said breathable fabric and the down blocking fabric.
[0015] The breathable fabric made using ramie fibers and polyester fibers is woven with a large pore space between the ramie fibers and the polyester fibers and is filled with thermal expansion particles, which are made of thermal expansion and cold contraction materials, which are easy to match with the ellipsoidal concave portion, and which contract in the case of cold, at which time the fluff is quickly filled into the ellipsoidal concave portion, which serves as thermal insulation, and on the other hand, the preheated expansion is replaced by the ellipsoidal concave portion. At this time, the hollowed-out portion is flat and the spacing of the fluff arranged on the ultrafine bamboo charcoal fibers increases, thereby playing a role of rapid air permeability.
[0016] According to another optimized solution of the present invention, said waterproof layer is obtained by spraying a waterproof coating on the outer surface of a polyester fiber, and said waterproof layer is provided with a pleated surface on the inner surface, which makes the waterproof layer self-assembling and easy to spread.
[0017] According to another optimized solution of the present invention, said insulating layer comprises an insulating fabric woven from wool fibers and cotton fibers, said insulating fabric is provided with ellipsoidal protrusions on the inner surface, the wool fibers and the cotton fibers have a good heat-keeping effect and can greatly reduce heat loss.
[0018] The present invention also relates to a method for preparing a waterproof, warm and leak-proof luxury down jacket fabric, the preparation process comprising the following steps:
[0019] SI: soaking ultrafine bamboo charcoal fibers in a mixing container and adding silver nanoparticles in quantitative batches, setting down-locking fabric composed of wool as well as bamboo charcoal fibers, performing mixing, drying and finishing to manufacture the down-locking layer;
[0020] S2: soaking the breathable fabric in a solution containing thermal expansion particles, heating and stirring, and drying to produce a breathable layer;
[0021] S3: Take an ellipsoidal bump template, hot press on the surface of the insulating fabric and form an ellipsoidal bump insulating fabric, to obtain the insulating layer
[0022] S4: Forming a waterproof, warm and filling leak-proof luxury down jacket fabric by hot pressing technology of a waterproof layer, an insulating layer, a breathable layer and a down blocking layer obtained by spraying a waterproof coating on the outer surface of the polyester fiber. Advantageously, during the hot pressing process, the thermal expansion particles inside the breathable layer are subjected to thermal expansion and form a molten state and pass through the waterproof layer and the breathable layer, which greatly improves the adhesive force between the waterproof layer, the insulating layer and the breathable layer.This greatly improves the adhesion force between the waterproof layer, the insulating layer and the breathable layer, making the fabric of the luxury waterproof warm down jacket have good integrity, and when the thermal expansion particles are contracted by the cold, they shrink the internal pores of the breathable fabric as a whole, avoiding heat loss on the one hand, and at the same time having a good anti-puncture effect, making the synergy between the breathable layer and the waterproof layer, the heat preservation layer, and the down locking layer good.
[0023] As a further optimization scheme of the present invention, in step S1, said silver nanoparticles are added in at least three batches incrementally, and the dosage of the first addition is 1.5 times the dosage of the second addition, so as to make the adsorption of the silver nanoparticles and the ultrafine bamboo charcoal fibers more even by adding the silver nanoparticles in batches, avoiding the silver nanoparticles being invested in one batch, and a large number of silver nanoparticles being adhered to the outer surface of the ultrafine bamboo charcoal fibers. The silver nanoparticles adhere to the outer surface of the ultrafine bamboo charcoal fibers, making them difficult to penetrate into the interior of the ultrafine bamboo charcoal fibers, which, on the one hand, leads to uneven adsorption of the upper and lower layers of the ultrafine bamboo charcoal fibers and, on the other hand, increases the stirring load and affects the adsorption effect of the ultrafine bamboo charcoal fibers and silver nanoparticles.
[0024] According to another optimized solution of the present invention, in step S2, the heating temperature is 100-150°C and the rotation speed of the stirrer is 1500-2000 rad / S.
[0025] According to another optimized solution of the present invention, in step S3, said hot pressing temperature is 90 - 120°C.
[0026] The beneficial effect of the present invention is as follows: the luxury down jacket fabric waterproof, warm and prevent the filling from leaking, through the use of wool and bamboo charcoal fibers interwoven to form a down locking layer, the bamboo charcoal fibers can effectively alleviate the above shrinkage condition, while the bamboo charcoal fibers can eliminate odor, release trace elements, have low electrical conductivity and play an antistatic role, can emit far infrared rays, the wavelength is suitable for the absorption of the human body, to accelerate the circulation of blood, and to improve the environment inside the human body, through the enclosing fabric made of wool as well as bamboo charcoal fibers is comfortable and easy to keep warm with good effect,and can effectively alleviate the shrinkage effect caused by wool.
[0027] Furthermore, the depression section is uniformly distributed on the inner surface of the hair blocking fabric, and the ellipsoid-shaped depression section exists in a long diameter direction and a short diameter direction in the space, which, on the one hand, strengthens the elasticity of the hair blocking layer in the space and, on the other hand, when the short diameter direction of the ellipsoid-shaped depression section expands and instantly releases the elasticity, the short diameter direction of the ellipsoid-shaped depression section undergoes rapid reset and generates a relative impact force on the surface of the hair blocking fabric.The relative impact force is generated, and the impact force makes the down evenly distributed on the inner surface of the down blocking fabric swell, and by imitating the "bursting cotton principle", the down inside the long-lasting down jacket is swollen, and the warmth-keeping effect of the down jacket is greatly improved.
[0028] The ellipsoidal depression is provided with a number of groups of ultrafine bamboo charcoal fibers in a conical structure. On the one hand, since the ultrafine bamboo charcoal fibers are provided with a number of groups and the spines are formed by the interlacing of the adjacent ultrafine bamboo charcoal fibers, the roots of the fluff are easily attached to the spines and the fluff is easily blocked by the ultrafine bamboo charcoal fibers in the spines, which can effectively prevent the down inside the inner lining from leaking out. On the other hand, the ultrafine bamboo charcoal fibers contain spherical silver nanoparticles, which have a good antibacterial effect and can effectively eliminate the bacteria carried by the down; therefore, the overall comfort and antibacterial properties are good.On the other hand, the recessed portion corresponds to the thermal expansion particles described below, and when the thermal expansion particles are subjected to thermal expansion, the recessed portion is caused to be in a flat state, at which time the ultrafine bamboo charcoal fibers in the recessed portion open inward, facilitating the release of fluff at the ultrafine bamboo charcoal fibers, and facilitating the rapid cleaning of the fluff in the recessed portion during cleaning, avoiding the creation of a dead space for cleaning, which results in localized mold.
