Description

A kind of high-elastic fire-retardant warming flaky material of thin-film multilayer flocking formula and manufacture method thereof
Technical field
The present invention relates to the high-elastic fire-retardant warming flaky material of a kind of thin-film multilayer flocking formula and manufacture method thereof, belong to field of textiles.
Background technology
In life in the past, the tradition that people's use is prepared using cotton, fiber crops, silk, hair and common terylene, polyamide fibre, acrylic fibers and artificial fibre etc. is heat insulating material formed as heat insulating material formed, during these are heat insulating material formed, silk and wool warmth retention property are better, but the easy breed bacteria of fiber, not resistance toly to damage by worms, and silk is expensive, wool fibre has peculiar smell, forming degree poor, and the cashmere price after multiple working procedure processing is more expensive, and the scope of application is limited to for many years.Along with living standard and scientific and technical development, people start will heat insulating material formed with regard to development of new, occur that by terylene, polypropylene fibre and acrylic fibers be main chemical fibre insulation flocculus, as the far infrared such as gum sprayed cotton, acupuncture cotton, space wadding, hot melting wool, melt-blown far infrared cotton, ultra-fine hot melting wool, down-like cotton.The principal mode of heat trnasfer has heat transfer, heat radiation and thermal convection current three kinds of modes.Material characteristics and internal structure determine the speed of its heat conduction velocity under normal circumstances, material internal structure and outer shape determine the quality of its heat radiation and antiradiation performance, its ability keeping still air and stop air flowing of material shape and structures shape.Traditional heat insulating material formedly to carry out between increased fiber still air layer to improve thermal property mainly through increasing thickness and density.The thickness of usual material is larger, density is less, the warmth retention property of material is larger, if but the density of material is too small, when causing air wherein to produce convection current, heat-insulating property declines on the contrary, for clothes with for heat insulating material formed, thickness is crossed conference and is caused the volume ratio of clothes more too fat to move, is not easy to motion and lacks aesthetic feeling again.Therefore, the exploitation of novel heat-preserving material becomes the main flow of heat insulating material formed research with research.The novel heat-preserving material developed in recent years also has far-infrared warm material, sunlight heat accumulation thermal material, medium phase-changing and temperature-regulating material etc., this kind ofly heat insulating material formedly not only follow traditional heat-insulation warm keeping principle, and can by some other form, such as absorb external heat, store and produce fuel factor to human body transmission, or solar energy, electric energy and chemical energy etc. are changed into heat energy to reach the object of heat-insulation warm keeping.In order to the insulation flocculus that processability is more excellent, static flocking technology is also incorporated into the preparation of insulation flocculus.Utilize static flocking technology to combine with traditional insulation flocculus manufacture method to prepare Novel heat-preservation flocculus and have bibliographical information.As Chinese invention patent application publication No. CN102493128A, denomination of invention is a kind of manufacture method of melt blowing warm retention wadding, this application case discloses a kind of manufacture method of melt blowing warm retention wadding, heat-accumulation temperature-adjustment staple fibre is implanted in the middle of melt-blowing nonwoven by electrostatic field, obtained melt blowing warm retention wadding.This method utilizes static flocking technology, staple fibre is implanted to nonwoven web inside, little to the performance impact such as elasticity and bulkiness of insulation flocculus.In daily life, fire safety is the problem that people attach great importance to, the common textiles overwhelming majority is inflammable or flammable, the promoter of disaster is easily become when running into the disasters such as fire, and take in insulation flocculus fire-retardant mechanism of introducing, can greatly delay and avoid the harm that the condition of a fire may cause.In present insulation flocculus product, can realize high elasticity, bulkiness, warmth retention property and the insulation flocculus with fire resistance compares shortage, therefore, a kind of high-elastic fire-retardant insulation flocculus of preparation has realistic meaning.
Summary of the invention
