Description
Technical field
The invention belongs to fibrous material field, particularly to the environment-friendly type regeneration negative ion far-infrared short fibre of function flame-resistant terylene
Dimension.
Background technology
Ordinary polyester fiber has excellent wearability and the scope of application widely, has exceeded cotton as textile raw material consumption
Flower, but also exists some serious shortcomings, on the one hand the warmth retention property of dacron is poor and the goods such as plastics, chemical fibre discarded after not
Degrade easily, thus directly utilize fossil resource production in enormous quantities polyster fibre and resulted in the great wasting of resources and environment dirt
Dye；On the other hand, the limited oxygen index (LOI) of terylene is about 21, along with the extensive application of fabric, and its fire potential
Danger also becomes increasingly conspicuous.The health-care effect of human body is confirmed by negative aeroion already by medical circle, the most increasingly by vast consumption
Person is cognitive, and Negative ionic textile can constantly release negative aeroion, to reach health care and to eliminate abnormal flavour, purify the dual of air
Effect.Negative ionic textile owing to directly wearing, large area and contact human skin, the heat energy of available human body and human body
Accelerate the generation of negative aeroion with rubbing of skin during motion, i.e. form an anion air layer at skin with check room,
Be conducive to oxygen-derived free radicals Non-toxic in human body, eliminate the oxygen-derived free radicals multiple harm to health.The biological effect of far infrared
Its frequency should be with to constitute the molecule of biological cell, intraatomic vibration ratio identical, so easily being absorbed by organism
Making intramolecular vibration strengthen, activation histiocyte blood circulation promoting accelerates metabolism.Due to the effect of far infrared, make
Molecular entergy level in organism is excited and is in higher vibration level, and this will improve the biomacromolecules such as nucleic acid protein
Activity, thus play it and adjust organism metabolism, improve the effect of immunity of organisms.By anion function, far-infrared functional, fire-retardant
It is the starting point of the present invention that function, environment-friendly function combine.
Anion can improve atmosphere quality, protection health, is the important of measurement air quality clean-up performance
One of index.In recent years, dense population areas, big city also exists anion and consumes abnormal serious protrusion phenomenon, and this allows for newly
The research and development of type anion releasable material become the focus in Research of Environmental Sciences field.Far infrared shakes with human inner cell's molecule
Dynamic frequency is close, " life light wave " penetrate into internal after, the atom of human body cell and the resonance of molecule will be caused, through sympathetic response
Absorbing, between molecule, frictional heat forms thermal response, promotes subcutaneous deep temperature to rise, and makes Marjoram Extract, accelerates blood
Circulation, is conducive to removing blood vessel and hoards thing and internal harmful substance, will harm metabolic obstacle cleaning, again make tissue multiple
Live, promote that ferment generates, reach to activate histiocyte, prevent aging, the purpose of strengthening immune system.So far infrared for
The multiple disease that blood circulation and microcirculation disturbance cause is respectively provided with improvement and preventive and therapeutic effect.Far infrared is applied to anion
Terylene short fiber is also made vehicle material, household material, heat insulating material formed etc. can effectively be improved living environment, improves health.
But terylene is a kind of inflammable substance, it is widely used and adds the probability that fire occurs, and this is to the person and property safety band
Carry out hidden danger.Therefore, coordinating flame-retarded technology, the application of terylene short fiber will be more wide.
The far-infrared negative-ion chopped fiber provided in the market mainly uses Surface-micromachining process fine to conventional polyester
Dimension carries out arrangement and prepares, or adds far-infrared negative-ion master batch making fiber in primary polyester slice, though the former can temporarily protect
Hold far-infrared negative-ion function, but the time one is long or can lose effect after washing, and the latter's far-infrared negative-ion function effect
Fruit is preferable, and function is lasting, but owing to manufacturing cost is higher, have impact on promoting the use of of product.
In the prior art, oneself has many foreign literatures fine to health fiber or far IR fibre or their mixed function
Dimension and fabric thereof have carried out deep discussion and discussion, and also oneself comes into the market to possess the fiber of this respect function and fabric.But
These functional fibres or there is far-infrared functional, or there is negative ion-releasing function, act on the most single.
