Description
The present invention relates to the manufacturing technology of a kind of new function fiber and goods thereof, specifically be a kind of when variation of ambient temperature, take place to change mutually to absorb or discharge heat energy by the polymer of forming fiber, thereby make fiber and goods have the manufacturing technology of the fibrous and goods of two-way adjustment effect.
Just string (as cotton, fiber crops etc.) and animal fiber (as silk, hair, eider down and fur etc.) the making resisting cold clothes that utilize occurring in nature to have good heat preservation effect have been understood though ancient times is human, but arrived the twentieth century middle and later periods, growth along with world population, no matter natural fabric on output, still all can not satisfy human growing demand qualitatively.So, artificial fibre and synthetic fiber technology have obtained extensive studies and development, with viscose glue, polyvinyl, polyamide fibre, terylene, acrylic fibers etc. is that the imitative cotton, simulate wool of raw material, imitative fiber crops, imitative silk and down-like fiber are dropped into suitability for industrialized production in succession, and becomes the main flow of insulation dress material research and development gradually.
Present existing animal and plant fiber and space or the inside and outside circulation of air of the isolated clothes of interlayer artificial and that synthetic fiber all utilize fibrous woven or braiding back to form reach the insulation purpose.When ambient temperature raises or reduce, temperature also can correspondingly increase or reduce in the clothes, and it is sultry or cold that people will feel, but when the amplitude of variation of ambient temperature exceeds the regulating power of human body self, can cause the many discomforts of human body, even cause disease.
In recent years, along with the raising day by day and the related discipline of people's quality of life constantly makes progress, especially air conditioner refrigerating broad application, people no longer are satisfied with the original passive insulation effect that can only be risen by secluding air circulation of conventional textile fabric, wish to develop the fiber that itself has temp regulating function, for example, European patent EP 302141 discloses a kind of carbide and aluminium micro mist with the IV transiting group metal elements and sneaks into thermoplastic polymer together, and further makes the method with energy absorption fiber after the spinning.This fabric is after having absorbed the infrared ray in the sunshine, and temperature can be high 3～8 ℃ than the conventional fibre fabric in the clothes, improved the insulation usefulness of fiber.But it is at the cloudy day or when night, environment temperature descended, and temperature also descends thereupon in the clothes, and the temperature difference of its result and conventional fibre inner not quite that is to say that its temp regulating function is unidirectional.
The manufacture method of another kind of temperature-regulating fiber again for example, is disclosed in the U.S. Pat 3607591.After it dissolves in solvent with gases such as carbon dioxide, be filled in the hollow space of fiber, and before weaving processing, hollow space sealed.This fiber dissolves in solvent at low temperatures by carbon dioxide and the energy variation when at high temperature separating out from solvent, can obtain having the fiber of energy absorption and release action.Though this fiber is two-way on temperature adjustment function, be unsettled on performance, such as when fiber in use is subjected to ambient pressure, very easily gas being leaked, cause losing suddenly or gradually of temperature adjustment function, while manufacturing technique complexity, cost height.
Again for example, a day disclosure is speciallyyed permit to disclose among the flat 4-163370 and is a kind ofly mixed 70 parts of paraffin (fusing point is 52 ℃) and 30 parts of high density polyethylene (HDPE)s afterwards that the melt spinning manufacturings have the method for temp regulating function fiber.When environment temperature raise, the paraffin in this fiber can pass through to absorb external heat and fusion; When ambient temperature reduced, liquid paraffin crystallization curing discharged the heat of transformation, thereby makes fiber have two-way adjustment effect, kept the temperature in the clothes relatively stable.But in order to prevent that paraffin from use from the fiber surface escape, needing at fiber surface coating epoxy resin, this obviously makes the weaving of fiber and takes performance can not be satisfactory, and technology is also complicated.
The objective of the invention is at above-mentioned defective, provide that a kind of technology is simple, cost is low, and have the fiber of better two-way adjustment effect, stable performance.This fiber and goods thereof can be according to the variations of ambient temperature, the transformation mutually of the polymer by forming fiber, absorb or discharge heat energy, thereby make fiber and goods thereof have the active temperature regulatory function, but and keep or says and do not reduce the original textile processibility of fiber and take comfortableness.
The object of the present invention is achieved like this: with melt temperature is 20～40 ℃, more than the melting heat 30J/g, 20～5 ℃ of crystallization temperatures, the above thermoplastic polymer of crystallization heat 30J/g is a polymer A, is polymer B with melt temperature at the conventional thermoplastic polymer more than 150 ℃, polymer A is the principal component of fibre core or island component, polymer B is the principal component of fibrous sheath or sea component, and the weight ratio of polymer A and polymer B is 2～8: 8～2, handle through the composite molten spinning and through drawing-off, the typing of routine, can obtain the fiber of the object of the invention.
The present invention is only by a melt spinning moulding, and do not need through other special post processing, can obtain having the fiber of two-way adjustment effect, therefore technology is simple, cost is low, and contained at fibrous inside by the sheath of fiber or sea component with the core of fiber or the form of island component owing to have the material-polymer A of heat absorption and release function, avoided fibre property deterioration in use, so stable performance of fiber and goods thereof, temperature adjustment function is better, but the while does not also influence or says the textile processibility energy that does not reduce fiber at least and take performance.
