Abstract
The invention discloses a rapid high-rebound high-heat-preservation floccus flake and a preparation method thereof. The elastic heat-preservation floccus flake is prepared by processing raw materials of superfine polyster fiber, hollow fiber with triangular or special-shape holes therein, composite elastic fiber, viscose fiber, polyster fiber with common properties and hollow fiber with a round inner part. The floccus flake is prepared by blending novel high-performance fiber, special fiber, functional fiber and the conventional fiber in different ratios. The obtained floccus flake has the characteristics of quick and high rebound resilience and high heat preservation. The floccus flake meets requirements on lightness of a sleeping bag, compression and rebound, heat preservation, comfortability and the like. The product overcomes the defects of the heat-preserving floccus flake in the conventional sleeping bag, and increases heat preservation ratio and compression resilience ratio.
Description
Technical field
The present invention relates to high insulation flocculus of a kind of quick high resilience and preparation method thereof.
Background technology
At present both at home and abroad the insulation flocculus that uses of sleeping bag mainly contains gum sprayed cotton (containing the elastic force flocculus), hot melting wool, imitative silk flosssilk wadding, melts and sprays cotton, and performance, characteristics are different.
Gum sprayed cotton is the most frequently used common flocculus, advantage be fluffy, resilience good, thickness is arranged, shortcoming is coarse, water-fast the washing not of feel, warming rate is not high.The elastic force flocculus has just increased a small amount of viscose fibre in the gum sprayed cotton production technology, warming and the resilience effect is the same substantially with gum sprayed cotton.
Hot melting wool claims no collodion again, is to utilize viscose fibre as bonding process, and the surface is spraying binder not, is characterized in that air spots is sliding, and floating hair easily gets out the material in face, and warming rate is not high.
Imitative silk flosssilk wadding, the fiber number of fiber than common gum sprayed cotton carry out hot-rolling and plate behind the more surperficial spraying binder, advantage is a surface smoothing, and feel is smooth, water-fast washing, and shortcoming is that compression resilience is relatively poor, and elasticity is bad, and warming rate is high than gum sprayed cotton.
Melt and spray cotton, composition is a polypropylene fibre, through melt-blown process production, with 100g/m
2Be main below the specification.Be characterized in that warming rate of use initial stage is higher, along with using warming rate obviously to descend repeatedly, and easily harden that compression resilience is relatively poor.
Ultra-fine polyester fiber: generally be meant the fiber of fibre number below 0.8dtex, it is a kind of business-like novel synthetic fiber kind that is grown up by Japan phase early 1970s.Claim down-like cotton again, but be the fine fibre of present non-woven production line combing that be characterized in that fiber is superfine, match can effectively be filled up the fibre web space like eider down after the mixing, increase fiber specific surface area, improves the warming rate of flocculus.
Preserve Lay suede fiber, it is a kind of novel high hollow polyester fibre, fiber lumen is sharp triangle, has the same hollow structure of polar bear fur structure, hollow rate is up to 20%, characteristics are flat greatly and not, broken greatly and not, make have light weight behind the flocculus, fluffy, elasticity is lasting, soft, heat-insulating property is excellent.
Composite elastic fiber: be generally bi-component and the curling fiber that is heated.The PET/PBT composite elastic fiber, fiber is made of left and right sides different components, entering the variation that bends of the different left and right sides composition of drying room heating back melting point, forms permanent elastomer.PBT/PET composite elastic fiber and goods thereof are soft, and hygroscopicity, ABRASION RESISTANCE and fiber crimp are good, and the tensile elasticity and the elasticity of compression are fabulous, and its elastic recovery rate is better than the hollow polyester fiber.
Viscose fibre is low-melting-point composite fiber again, is commonly called as core-skin fibre, and the fusing point on fiber top layer and vitrification point are lower than the conventional polyester fiber, be mixed into net enter drying room after the low-melting-point composite fiber fusion, the bonding fibre web.Its effect is that the flocculus pulling force is strengthened, and has water-wash resistance.
Conventional fibre is ordinary polyester fiber (being the polyster fibre of common performance) or common hollow polyester fiber (being that cavity is circular doughnut).
Summary of the invention
The purpose of this invention is to provide a kind of elasticity insulation flocculus and preparation method thereof.
Elasticity insulation flocculus of the present invention obtains according to being prepared as follows method.
The unit mass of elasticity insulation flocculus of the present invention is 149g/m
2, clo value is 2.38, compressive recovery rate is 97%.
The method for preparing the elasticity insulation flocculus provided by the present invention, comprise the steps: that polyster fibre and the rounded doughnut of cavity with ultra-fine polyester fiber, cavity doughnut triangular in shape, composite elastic fiber, viscose fibre, common performance are raw material, processing obtains the elasticity insulation flocculus.
In the said method, the ratio of quality and the number of copies of the doughnut that the polyster fibre of described ultra-fine polyester fiber, cavity doughnut triangular in shape, composite elastic fiber, viscose fibre, common performance and cavity are rounded is: 15～25: 15～25: 5～15: 7～10: 10～25: 15～25, or 15～25: 15～25: 5～15: 7～10: 15～25: 15～25, or 15～25: 15～25: 5～15: 7～10: 10～15: 15～25.
In above-mentioned arbitrary described method, described composite elastic fiber is the PET/PBT composite elastic fiber; The fusing point of described viscose fibre is 150 ℃; Described cavity doughnut triangular in shape is that cavity is sharp leg-of-mutton doughnut.
In above-mentioned arbitrary described method,
