Description
Technical field
The present invention relates to functional fiber and its product technique field, specifically a kind of production method of temperature-regulating fiber with
And the temperature-regulating fiber made of this method, further relate to the thermostat quilt made of the temperature-regulating fiber.
Background technique
Scientific investigations showed that 32 DEG C of quilt helps to improve the sleep quality of people, at this temperature people be easiest into
It sleeps.Because the skin temperature of people is 5 DEG C lower than body temperature, about 32 DEG C or so, quilt temperature is low, needs to be warmed up with body temperature for a long time
After heat not only expends the thermal energy of human body, but also body surface is subjected to the cold stimulation of a period of time, cerebral cortex can be made excited, thus
People's time for falling asleep is postponed, if quilt temperature is higher than 32 DEG C, human body is equally because feel that too hot needs perspire cooling, to reduce
Sleep quality.
Intelligent thermoregulating is based on above-mentioned phenomenon, and the temperature of control quilt is adjusted using temperature adjustment heat accumulating phase change material, makes its perseverance
32 DEG C or so are scheduled on, to help to maintain nice and cool, comfortable healthy sleep environment.Intelligent thermoregulating is usually by with temperature adjustment
Functional material is made, and play temperature adjustment function is the phase-change material (PCM) added in quilt.PCM material in intelligent thermoregulating cloth
Material can be absorbed, store and discharge heat, and temperature Gao Shike can be warmed with absorbing and cooling temperature when temperature is low with heat release, to play
Temperature adjustment effect.
Such as the utility model patent of Publication No. CN105411301A discloses a kind of self-temperature-regulating quilt, including by sublist
The filler filled in face and quilt surface, quilt surface are viscose rayon and the Outlast acrylic fiber containing phase-change material
It is blended at fabric, filler material be polyester filament and Outlast acrylic fiber containing phase-change material it is blended made of, fill out
Fibres are filled using concaveconvex structure.
In addition, the utility model patent of Publication No. CN201248559Y discloses a kind of Intelligent temperature regulating bedding article, by
Wadding part composition is cased in outer cover or outer cover, the outer cover is docked by common textile fabric with the temperature adjustment textile fabric with phase-change material
Bilayer is sewn into form；The wadding part be made of the temperature-regulating fiber with phase-change material or by commonly wad a quilt with cotton part layer with phase-change material
Temperature-regulating fiber layer is compound or mixes.Make band phase-change material using the fabric with phase-change material or wadding part on articles in bed
Fabric or wadding part portions proximate human body, by the conversion process of the solid-liquid of phase-change material at different temperatures absorb heat or
The phenomenon that heat release, to realize that the comfort level to human body temperature is adjusted.
Although above-mentioned patent is provided with certain thermoregulation effect, the addition manner of phase-change material and the shape in quilt
State determines the temperature adjustment function quality of product.Due to added in non-woven fabrics phase-change material difficulty is big, phase-change material in the product
Attachment stability is poor, and additive amount is lower, thus causes finished product thermostat quilt thermoregulation effect poor, and human feeling is unobvious, furthermore phase transformation
The latent heat of material is unable to satisfy the heat exchange demand of bedding in many cases.
