Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of special textile materials, in particular to an aluminum foil wrapped pile yarn, a cold-resistant outdoor fabric and a preparation method thereof. BACKGROUND

[0002] In extreme environments such as deserts, plateaus and polar regions, outdoor equipment fabrics need to meet multiple stringent requirements: extremely high ultraviolet resistance, excellent wind and dust resistance, heat insulation to cope with large temperature differences, and long-term weather resistance and aging resistance. Traditional solutions mostly use multi-layer composite materials, such as sunscreen coating on the outer layer and metal-coated reflective layer in the middle. However, the whole metal film (such as aluminum foil) laminated fabric has obvious defects: hard texture, not resistant to repeated folding and bending, easy to crack at low temperature, the metal layer is damaged, the overall function is lost, and the fabric's air permeability and flexibility are affected, shortening the product's service life, making it difficult to meet the needs of tents and other equipment that need to be frequently set up and folded.

[0003] Therefore, there is an urgent need to develop a new type of outdoor fabric that can maintain high-efficiency heat reflection performance while having excellent flexibility, fatigue resistance and environmental durability. SUMMARY

[0004] The present application aims to overcome the shortcomings of the prior art and provide an aluminum foil wrapped pile yarn, a cold-resistant outdoor fabric using the yarn and a preparation method thereof. The present application innovatively integrates micro-flaky aluminum foil into the yarn and uses it as the inner layer of the fabric, which significantly improves the overall flexibility, wrinkle resistance, low-temperature impact resistance and service life of the fabric while ensuring high-efficiency infrared reflection.

[0005] To achieve the above-mentioned purposes, the technical solutions of the present application are as follows: An aluminum foil wrapped pile yarn is composed of two parallel high-strength low-elongation polyester filaments as core yarns, polyester monofilaments as pile yarns, and flaky aluminum foil. The thickness of the aluminum foil sheet is 6-10 microns, the width is 1-2 mm, and the length is 5-10 mm. The surface of the aluminum foil sheet is preferably treated with a silane coupling agent to enhance its interfacial bonding force with polymer fibers. The preparation method of the aluminum foil wrapped pile yarn includes the following steps: The surface-treated aluminum foil sheet is regularly arranged between the two parallel and equally running core yarns at an equal interval of 5-8 mm. A polyester monofilament is used as a pile yarn to wrap the aluminum foil sheet in a S or Z direction, and the aluminum foil sheet is clamped and tied in the middle of the two core yarns. The above structure is processed by double roller differential drafting and rotary twisting mechanism of a chenille spinning machine. The differential drafting makes the pile yarn form a fluffy pile bundle structure, while the rotary twisting makes the core yarn and the wrapped pile yarn tightly combined, finally embeds the aluminum foil firmly into the yarn body, and makes part of the aluminum foil edge slightly protrude from the pile bundle, forms a radial structure, and obtains the finished aluminum foil wrapped pile yarn.

[0006] Further, the finished yarn is treated by low temperature plasma, further activates the fiber surface, and improves the composite fastness of the aluminum foil and the polyester fiber.

[0007] An inner layer fabric for cold-resistant outdoor fabric is woven by the above aluminum foil wrapped pile yarn, and the preparation method comprises the following steps: Weaving: using a weaving process, using ordinary polyester filaments as warp yarns, using aluminum foil wrapped pile yarns as weft yarns, and using plain or twill weave to weave; Yarn density control: during weaving, the arrangement density of the aluminum foil wrapped pile yarn is controlled to be 15-25 roots / cm, so as to ensure that the effective heat reflection coverage rate of the aluminum foil formed after weaving is not less than 80%; Finishing: calendering treatment is carried out at a moderate temperature and pressure, the slightly protruding aluminum foil is slightly laid down, optical scattering is reduced, and the consistency and efficiency of infrared reflection are improved; The finished inner layer fabric is obtained.

[0008] Further, in the weaving step, a double-layer weaving structure is used, ordinary polyester yarns are used as upper and lower surface layers, and the aluminum foil wrapped pile yarn is inserted as a connecting yarn in the weft direction in the middle to form a "sandwich" structure, so that the reflection layer is inside the fabric.

[0009] Further, after the finishing step is completed, a layer of transparent flame-retardant silicone resin coating is sprayed on the fabric surface. The coating can effectively prevent the aluminum foil from oxidizing in use, endow the fabric with flame-retardant properties, and at the same time maintain the soft hand feeling required by the fabric.

[0010] A cold-resistant outdoor fabric is a three-layer composite structure of an outer layer, an intermediate functional layer and an inner layer. The outer layer is a composite functional layer of an ePTFE microporous membrane and nano-oxide. First, a nano-zinc oxide or titanium dioxide coating is sprayed on the surface of the ePTFE membrane by a sol-gel method, and a firm ultraviolet shielding layer is formed after solidification. On the outer surface of the layer, further nano-scale ceramic particle (such as silicon dioxide, aluminum oxide) spraying treatment can be carried out to build a high-efficiency and durable physical sunscreen and wear-resistant surface; The intermediate functional layer is a composite of aramid 1414 or UHMWPE woven fabric and phase change microcapsules. The aramid or UHMWPE fabric is immersed in an aqueous polyurethane resin containing phase change material microcapsules, and the PCM microcapsules are uniformly embedded between the fibers and the surface of the fabric through pad-dry-cure process; The inner layer fabric is prepared by wrapping the inner layer fabric with the aluminum foil and the wool yarn.

[0011] A preparation method of a cold-resistant outdoor fabric, comprising the following steps: (1) intermediate functional layer preparation: clean and perform plasma pretreatment on aramid or UHMWPE fabric to improve surface energy. Then, the aramid or UHMWPE fabric is immersed in an aqueous resin finishing solution containing shaped phase change microcapsules, a two-dip-two-nip process is adopted, and the liquid rate is controlled. Then, pre-drying is performed at 80-110 DEG C, and then curing is performed at 130-150 DEG C for 2-5 minutes, so that the resin is cross-linked and solidified, the PCM microcapsules are firmly attached, and the PCM-loaded functional fabric is obtained; (2) outer layer film treatment: perform corona treatment on the ePTFE microporous film to activate the surface. A nano-zinc oxide or titanium dioxide sol is prepared, and is uniformly coated on the film surface by ultrasonic spraying, and is cured in a 120-150 DEG C oven for 30-60 minutes to form a nano-composite ultraviolet shielding layer. Then, nano ceramic slurry can be sprayed on the outer surface again and cured to form the outermost protective layer; (3) inner layer fabric preparation: the aluminum foil wrapped wool yarn inner layer fabric is woven and post-treated; (4) three-layer composite: a hot-pressing composite process is adopted. Two layers of modified silicon hot melt adhesive net films are prepared. In the order of "outer layer (ePTFE film)--first layer of adhesive net film--intermediate functional layer (PCM / aramid fabric)--second layer of adhesive net film--inner layer fabric (aluminum foil yarn fabric)", the three layers are stacked. The three layers are sent into a hot-pressing composite machine, and hot pressing is performed at a temperature of 100-120 DEG C and a pressure of 0.3-0.5 MPa for 30-90 seconds, so that the adhesive film is melted and penetrates, and the three layers of substrates are firmly bonded into one whole.

[0012] Further, after the three-layer composite step is completed, the surface of the fabric is treated, the outermost layer (the surface of the ePTFE film) of the composite fabric is treated by low-temperature plasma fluorination, fluorine-containing monomers are introduced into the treatment gas, and a fluorinated layer with low surface energy is formed on the surface of the fabric, so that the fabric has persistent hydrophobic and oleophobic (antifouling) self-cleaning properties.

[0013] Further, the treated fabric is cooled, shaped, wound, and performance detection is performed according to standards, and finally the preparation of the cold-resistant outdoor fabric is completed.

[0014] Compared with the prior art, the present application has the following beneficial effects: The present application solves the problems of poor flexibility and fatigue resistance of the metal reflective layer by discretizing the traditional continuous metal film into micro-piece units protected by flexible fibers through the unique design of the aluminum foil wrapped wool yarn, and the three-layer composite fabric constructed based on the yarn has the following outstanding advantages: Excellent durability and flexibility: the aluminum foil is wrapped by the fiber, and the stress is dispersed when folding and rubbing, avoiding overall cracking, and the fabric feels soft and can be folded at will, especially suitable for tents and other products that need to be frequently folded and unfolded; Efficient and stable heat management: the inner layer of aluminum foil forms a high-coverage reflective layer that can efficiently reflect human body heat energy; the middle layer of PCM absorbs / releases latent heat, actively buffering temperature fluctuations; the outer layer of PTFE film and nano coating blocks external heat radiation and ultraviolet rays; the three work together to achieve excellent wide-temperature-range adaptability; Comprehensive environmental protection: the outer layer of ePTFE film and nano ceramic coating provides top-level ultraviolet resistance, weather resistance, wind resistance, and preliminary stain resistance; plasma fluorination treatment gives permanent self-cleaning properties; the overall structure is windproof and dustproof; Significant lightweighting and long service life: compared to traditional aluminum foil composite fabrics, the weight is significantly reduced while maintaining the core heat reflection function, and due to the physical isolation and protection of the aluminum foil by the fiber, the oxidation and mechanical damage resistance is extremely strong, and the expected service life is doubled.

[0019] The original intention of the present application is to provide a cold-resistant outdoor fabric that can adapt to extreme environments, especially in extreme environments such as deserts, highlands, and polar regions. It improves wind and sand resistance, withstands extreme cold, provides comfort and warmth, and is durable and sun-resistant. It is used in products such as jackets or tent fabrics.

[0020] REFERENCE Figs. 1 to 4 The following is a specific and easy-to-implement description of the present scheme: I. Preparation of aluminum foil wrapped pile yarn 1. Raw material preparation: Core yarn 1: high-strength low-elongation polyester filament (such as industrial-grade PET, specification 167 dtex / 48 f, breaking strength ≥ 5.0 cN / dtex, breaking elongation ≤ 15%) is selected, and two are arranged in parallel; Pile yarn 2: coarse denier polyester monofilament (specification 333 dtex, diameter about 0.2 mm) is used to wrap and fix the aluminum foil sheet; Aluminum foil 3: thickness 6-10 pm, width 1-2 mm, length 5-10 mm; preferably high purity (99.9%) electrolytic aluminum foil is used, which is cut into a specified size; Surface treatment agent: silane coupling agent (such as KH-550 or KH-560), prepared into a 1-2 wt% ethanol aqueous solution (pH = 4-5) for pretreatment of aluminum foil.

[0021] 2. Surface treatment of aluminum foil The cut aluminum foil is immersed in the silane coupling agent solution, soaked at room temperature for 10 minutes, and then dried in an oven at 60°C for 15 minutes. This treatment can significantly improve the interfacial bonding between the aluminum foil and the polyester fiber, preventing the aluminum foil from falling off during subsequent processing or use.

[0022] 3. Yarn forming process (chenille spinning method) A modified chenille spinning machine is used, which includes the following key mechanisms: Double-core yarn feeding device: two core yarns are fed in parallel at the same speed (e.g., 5 m / min); Aluminum foil automatic arranger: the treated aluminum foil is precisely placed between the two core yarns at an interval of 5-8 mm; Fleece yarn wrapping head: the polyester filaments wrap around the two core yarns in a Z-direction (or S-direction) spiral manner, with a wrapping pitch controlled at 3-5 mm; Differential speed drafting roller group: the front roller speed is 1.2-1.5 times faster than the rear roller, causing the fleece yarn to be stretched and fluffy, forming a "fleece bundle" structure; Rotary twisting mechanism: a weak twist of 50-100 twists / m is applied to the overall structure, causing the core yarn and the fleece yarn to be tightly combined, while the aluminum foil is firmly embedded inside the yarn body.

[0023] The final aluminum foil wrapped fleece yarn is in a cylindrical shape with a diameter of about 0.8-1.2 mm, and the aluminum foil is periodically distributed along the axial direction, with some edges slightly protruding from the surface of the fleece bundle, forming a radial reflective structure.

[0024] In some embodiments, the finished yarn can be treated by a low-temperature plasma treatment device (power 100-200 W, gas Ar / O2 mixture, treatment time 30-60 seconds) to further activate the fiber surface and improve the aluminum foil-polyester composite firmness.

[0025] II. Weaving and finishing of inner layer fabric 1. Weaving process Weaving machine type: high-speed rapier loom or air-jet loom; Warp yarn: ordinary polyester filament (167 dtex), treated with sizing to improve wear resistance; Weft yarn: the aluminum foil wrapped fleece yarn prepared above; Fabric structure: plain weave or 2 / 1 twill weave; Weft density control: adjust the beating-up mechanism to make the aluminum foil wrapping weft yarn density 15-25 ends / cm (i.e. 15-25 weft yarns per cm of fabric surface); Target effect: the aluminum foil sheet forms a continuous coverage on the fabric surface, and the effective heat reflection area is ≥80%.

[0026] Alternative: adopt a double-layer weaving structure. The upper and lower layers are both woven with polyester yarn to form a dense surface fabric, and the middle layer is wrapped with aluminum foil wrapping weft yarn as the weft connecting yarn (binding yarn) to form a "sandwich" structure, so that the aluminum foil reflection layer is completely wrapped inside the fabric to avoid exposure and wear.

[0027] 2. Finishing Calendering treatment: light calendering at a temperature of 80-100℃ and a pressure of 0.2-0.3MPa to make the slightly convex aluminum foil sheet slightly adhere to the surface, reduce diffuse reflection, and improve the consistency of infrared reflection direction; Flame-retardant coating: spray transparent flame-retardant silicone resin (solid content 20%, viscosity 50-100mPa·s), control the coating thickness to be 1-3μm, and dry and cure at 120℃. This coating can isolate oxygen and prevent oxidation of the aluminum foil, while also giving the fabric B1 level flame-retardant performance (GB / T 5455).

[0028] Three, assembly of three-layer composite cold-resistant outdoor fabric 1. Preparation of middle functional layer Base fabric: aramid 1414 (Nomex®) or UHMWPE woven fabric (warp and weft density 120×120 ends / 10cm); Pre-treatment: after washing with deionized water, air plasma treatment at normal pressure (power 150W, O2 atmosphere, 60 seconds) to improve surface energy; Preparation of immersion liquid: add phase change microcapsules (PCM, particle size 1-5μm, melting point 28±2℃, such as n-octadecane microcapsules) at 15-20wt% into water-based polyurethane resin (solid content 30%) and stir evenly; Double immersion and double rolling: control the liquid retention rate to be 80-100% and the rolling rate to be consistent; Drying and curing: first pre-dry at 80℃ for 3 minutes, then bake at 140℃ for 3 minutes to cross-link and cure the PU, and firmly adhere the PCM to the fiber surface and gaps.

[0029] 2. Outer film treatment Base film: expanded polytetrafluoroethylene (ePTFE) microporous film (porosity 80%, average pore size 0.2μm, thickness 25μm); Corona treatment: power 2kW, line speed 10m / min, surface tension increased to more than 45mN / m; Nano-coating: Titanium dioxide sol (5wt% concentration, ethanol as solvent) was prepared and coated uniformly by ultrasonic spraying (frequency 40 kHz), and cured at 130℃ for 45 minutes; Ceramic protective layer: Aqueous slurry containing silica / alumina nanoparticles (particle size 20-50 nm) was sprayed and cured at 150℃ for 30 minutes to enhance wear resistance and sand erosion resistance.

[0030] 3. Three-layer hot-pressing composite Adhesive film: Modified silicone hot melt adhesive film (melting point 95℃, grammage 20g / m²), with excellent low-temperature flexibility; Lamination sequence: ePTFE outer layer → first layer of adhesive film → PCM / aramid intermediate layer → second layer of adhesive film → aluminum foil yarn inner layer cloth; Hot-pressing parameters: temperature 110℃, pressure 0.4 MPa, residence time 60 seconds; Cooling and setting: Rapid cooling to room temperature by cold water roller, and winding.

[0031] 4. Surface functionalization In some embodiments, the outermost layer of the composite fabric (ePTFE surface) is treated by low-temperature plasma fluorination: C4F8 (perfluorobutene) and Ar (argon) mixed gas (ratio 1:4) is used, power 150 W, treatment time 90 seconds, to form a low-surface-energy layer containing -CF2 / -CF3 on the surface, contact angle >110°, achieving long-lasting hydrophobic and oleophobicity and self-cleaning.

[0032] From this, the preparation of the full-function cold-resistant outdoor fabric of the present solution is completed.

[0033] In summary, the present invention, through the unique "aluminum foil wrapping yarn" design, discretizes the traditional continuous metal film, which is prone to brittle fracture, into micro-piece units protected by flexible fibers, fundamentally solving the problem of poor flexibility and fatigue resistance of the metal reflective layer. The three-layer composite fabric based on this yarn has the following outstanding advantages: Excellent durability and flexibility: The aluminum foil pieces are wrapped by fibers, and the stress is dispersed when folding and rubbing, avoiding overall cracking. The fabric feels soft and can be folded at will, making it particularly suitable for products such as tents that need to be frequently folded and unfolded.

[0034] Efficient and stable thermal management: The high-coverage reflective layer formed by the inner layer of aluminum foil can efficiently reflect human body radiant heat energy; the intermediate layer of PCM absorbs / releases latent heat, actively buffering temperature fluctuations; the outer layer of PTFE film and nano-coating blocks external heat radiation and ultraviolet rays. The three work together to achieve excellent wide-temperature-range adaptability. Comprehensive environmental protection: outer ePTFE membrane and nano ceramic coating provide top-level UV resistance, weather resistance, wind resistance and preliminary anti-fouling ability; plasma fluorination treatment gives permanent self-cleaning property; the overall structure is windproof and dustproof; Significant light weight and long service life: compared with traditional aluminum foil composite fabric, the weight is greatly reduced under the premise of maintaining the core heat reflection function, and due to the physical isolation and protection of aluminum foil by fiber, the oxidation resistance and mechanical damage resistance are extremely strong, and the expected service life is doubled.
