Problems solved by technology

However, in the existing quality evaluation standards for down products, dust and dust rate are an important negative index that affects the quality of down. Not only can you not actively add dust, but you are also afraid that there will be too much dust, so you must first remove it and then quickly

Embodiment 1

[0073] Weigh 5 kg of airgel powder and 5 kg of down. In a closed sieve machine, first fully mix the airgel powder and down, and then spray polyacetic acid on the mixture of airgel powder and down with spray cotton equipment The fog-like adhesive (Bonding Agent) formed by vinyl ester micro-droplets is used to obtain preliminary airgel modified down, and then these down filled with airgel powder are assembled into a flat shape with a thickness of about 3 mm. structure, spray polyvinyl acetate aerosol again, and then assemble multiple planar structures into a planar or group structure suitable for filling airgel down jackets, and spray polyvinyl acetate aerosol again on its outermost surface Finally, these planar structures that have been sprayed with polyvinyl acetate aerosol for many times are filled into the down jacket fabric, and a kind of airgel down jacket with multiple anti-powder shedding structures can be obtained.

Embodiment 2

[0075] Weigh 10 kg of airgel powder and 1 kg of down, place the airgel powder and down in a closed down sorting machine or a mixing box to fully mix, and spray polyvinyl acetate on the surface of the down filled with airgel powder Ester aerosol, and then gather the velvet sprayed with polyvinyl acetate aerosol into multiple cluster structures, and then assemble multiple cluster structures into multiple planar structures suitable for filling in airgel duvets, Spray polyvinyl acetate mist on the surface of the planar structure again, and finally fill the planar structure sprayed with polyvinyl acetate into the duvet fabric to obtain a powder-proof, excellent heat preservation effect, but Extremely lightweight airgel duvet.

Embodiment 3

[0077] Weigh 5 kilograms of airgel powder and pour it into a sealed space with a volume of about 40 cubic meters, blow the poured airgel powder into a boiling shape with a fan arranged in the sealed space, and then condense it into the boiling air. The glue powder flow sprays silicone glue droplets at high speed. After the above airgel powder monomer is evenly wrapped, 5 kg of down is blown into the closed space. The particles are rolled and stirred repeatedly in a closed space together with the airflow, and then compacted to a thin layer with a thickness of about 2 mm to prepare a powder-proof, denser airgel modified down, which is used as a thermal insulation interlayer for clothing.

Abstract

The invention discloses an aerogel modified down material and its product. The aerogel modified down material includes down, aerogel powder and an anti-powder structure. The anti-powder structure fixes and / or the aerogel powder. Or confined in or on down; the anti-powder structure can be stickies and / or wrapping layers, through one or more stages of anti-powder structure, the aerogel powder is firmly bound or confined in the down product Avoid allergies, coughing, expectoration, sneezing, itching, eye confusion, chest tightness, dyspnea, dermatitis, rhinitis or other inflammations caused by aerogel powder dropping, and long-term use will lead to serious diseases such as pneumoconiosis or silicosis. It can also prevent the powder from falling off during the cleaning and rubbing process, or the aerogel reduction caused by the falling powder makes the thermal insulation performance worse, etc., which improves the use effect and service life of down products. The preparation method of the aerogel modified down in the present invention is simple and feasible, the process equipment is mature and reliable, the cost is low, and it is suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of heat insulation and / or heat preservation materials, and relates to an airgel-modified down material and products thereof (Aerogel-modified down materials and products), in particular to an ultrathin down jacket, down quilt and down underwear . Background technique [0002] Down is the natural fiber with the best thermal insulation performance known at present. Usually, what is used as a thermal insulation material is down feather (i.e. velvet) with a huge inner space after being stretched out. The velvet flower does not contain a rachis, but only contains a short and thick velvet nucleus, and around the velvet nucleus grows fine and soft velvet filaments, which are radial and shaped like pompoms; on the longer first-order velvet filaments grow shorter The second-order velvet has single or double thorns on the second-order velvet, and there are ring-shaped scales on each level of velvet, and the next-ord...
