Description
Technical field
The present invention relates to a kind of manufacture method of high-tension flame retardant polyester fiber, belong to technical field of textile fabric.
Background technology
Along with the development of science and technology, various functional textile constantly occurs, as antibacterial, uvioresistant, far infrared, the various functional fiber such as fire-retardant are constantly developed.And far infrared functional fibre be this year one newer gradually by the functional textile material that client approves, it has warming, health care, promotes people's body-internal-circulation and improve effect of body immunity.Far infrared functional fibre can be used for developing function accumulating product, the medical products etc. such as various warm, health cares, as underwear, warm-up next to the skin, down-coat packing, bedcover, sheet etc.
In electromagnetic spectrum, infrared ray is between visible ray and microwave, and its wavelength is 0.76 ~ 1000um.Infrared ray occupies very wide scope in electromagnetic spectrum, can be divided near, in, three parts far away, wavelength is called far infrared wave at the ripple of 4 ~ 1000um.Far infrared has following characteristics: the rectilinear propagation of light, refrangibility, reflectivity, penetrability.Its good fortune is penetrated very capable, directly can heat and do not make the gas in space or other objects heat up to target; Can be absorbed by the various objects consistent with its wave-length coverage, produce resonance effects and thermogenetic effect; Under penetrating into human body skin, then heat is made to be deep into cell tissue depths by mediator conduction and blood circulation.Any object all can have infrared ray outwards to have jurisdiction over to penetrate.In radiation wave band, when the atom in molecule or atomic group are converted to low-energy vibrational state from high-octane vibrational state, the far infrared good fortune that can produce 2.5 ~ 25um is penetrated, if linchpin penetrate source be by molecule rotational characteristic change caused by good fortune penetrate, then the far infrared good fortune that >25um occurs is penetrated.The energy of vibrational spectrum is about 100 times of rotation spectrum energy, and therefore in far wavelength chooses, 2.5 ~ 25um is high energy ripple, has good using value.
According to coupling absorption approach, when the wavelength that infrared good fortune is penetrated is corresponding with the absorbing wavelength of being penetrated object by good fortune, object molecular resonance absorbs.That is the hydrone of the molecular vibrational frequency of far IR fibre vibration number identical with tissue resonates, and hydrone absorbs energy and evokes again another vibration, and result is struck a chord resonant interaction.Far infrared has certain penetrability, the deep enough hypodermis of energy, cause dipole and free charge in organism that sequence vibration occurs under electromagnetic field effect, and then the random motion of molecule, atom is aggravated, produce thermal response, hypodermis is heated up, and then improve microcirculation, strengthen the power of regeneration of cell, improve the phagocytic function of immunocyte, promote the metabolism of organism and grow.
In the middle of practical application, although there are many far-infrared functional fibers present stage, the radiation in a certain CF can only be absorbed due to each far-infrared functional nano material, absorb that POP is narrow can not effectively transform extraneous emittance.
Although have the nano far-infrared material of one-component and the blended obtained far infrared functional fibre of PTT at present, far-infrared functional is unstable, low, the infrared conversion ratio of fibre strength and POP absorption frequency is narrow and the shortcoming such as fire-retardant rate variance.
