Abstract
The invention discloses a breathable multifunctional pillow inner with moisture penetrability filled with fibers. The fibers consist of three hollow fibers with circular arc cross sections. The circular arcs are connected in such a way that every two are externally tangent with each other, and a connected closed region is an entity. The hollow fibers are made from polyethylene terephthalate with the intrinsic viscosity of 0.65-0.66, the melting point of 266 DEG C, the carboxyl content of more than zero and less than or equal to 25 equivalent/g * 10<6>, and the ash content of more than zero and less than 0.04 percent. The breathable multifunctional pillow inner with moisture penetrability is made of fibers which are three-hole hollow fibers with three outward openings, thereby the pillow inner is breathable and has moisture penetrability. In hot rolling process, a shape with six interlaced holes can be formed between the adjacent fibers and the fibers have openings, thus the pillow inner made from the fibers has excellent moisture penetrability.
Description
Technical field
The present invention relates to a kind of breathable multifunctional pillow inner with moisture penetrability.
Background technology
Pillow is a chief component of pillow.The material of making pillow in the market is varied, and Chinese medicine such as cassia seed, mother chrysanthemum, silkworm excrement are wherein arranged; Cereals such as buckwheat shell, cavings, cotton are arranged; Also have rush, cattail wool, useless tealeaves etc. are filled as material, utilizing the material of modern technologies processing and fabricating such as porous vacuum cotton, slow resilience sponge etc. in addition all is the very high packing material of popularity rate on market.Why cereal and other plant material are considered to traditional packing material always, mainly are because they itself contain suitable rich in amino acid composition, and process skin friction and breathing can partly be absorption of human body in people's sleep.And the pillow material that modern technologies are made mainly is particular about the comfortable of pillow, and the most frequently used material is a doughnut.
Doughnut is the abbreviation that cross section has the chemical fibre of cavity vertically, is a kind of important profiled filament.Occurring in nature also exists multiple fiber with lumen such as kapok, arctic bear hair, the rabbit hair, cotton etc.The appearance of doughnut is the result that bionics is used, thereby the warmth retention property that cavity provides still air to improve fiber has increased the surface area in the unit volume, thereby has improved the bulkiness of fiber; Doughnut is to the adsorption capacity of media such as water, gas, blood, and during as composite and the binding ability of matrix material, not only improved the rigidity and the stiffness of fiber to a certain extent, but also improved the anti-bending strength and the anti-wear performance of fiber.The kind of doughnut is extremely abundant, development is rapid, and its raw material develops into polyamide fibre, polypropylene fibre, viscose glue, polyvinyl, polysulfones, carbon fiber etc. from initial terylene; Holes on synthetic fibres develops into four holes, seven apertures in the human head, nine holes etc. from single hole; Hollow section also develops into triangle, quadrangle, quincunx etc. from circle.It is airtight that but doughnut also has simultaneously, not wet thoroughly shortcoming.
Summary of the invention
The purpose of this invention is to provide a kind of breathable multifunctional pillow inner with moisture penetrability.
Breathable multifunctional pillow inner with moisture penetrability provided by the present invention, its packing material is a fiber, the doughnut that described fiber is a circular arc by three cross sections is formed, and three circular arcs are the circumscribed mode of two two-phases and connect, and it interconnects formed closed area is entity.
Wherein, described doughnut is made by PET, and the requirement of described PET is an inherent viscosity 0.65～0.66,266 ℃ of fusing points; Carboxyl-content≤25 equivalent/gram * 106, ash content＜0.04%.Described fiber is a global formation, and promptly raw material drops in the short silk of the VD406 type melt spinning machine, via the ejection of porous spinneret, obtains undrawn yarn, and the shape of this undrawn yarn is identical with the shape of fiber shown in Figure 2.The radius of described three circular arcs can equate.The angle of described three circular arcs can equate, also can be unequal.As long as the angle of circular arc is less than 360 degree, and purpose is to make doughnut not closed, the angle of described circular arc is set as to spend less than 360 more than or equal to 90 degree in process of production also can.The crispation number of described fiber determines that as required crispation number can be 4-5/centimetre.Fiber bulkiness height after curling, rigidity foot, good springiness.The length of described fiber is 51 ~ 65mm, and fiber number is 3.33dtex, the fiber of intensity 4.56 gram/dtex, fault 20 milligrams/100 grams.Described fiber carried out hot rolling to be handled, and roll temperature is 145 ℃ in the described hot rolling, 160 ℃ of following roll temperatures.
Breathable multifunctional pillow inner with moisture penetrability of the present invention, its material is a fiber, this fiber is the PET Hollow fiber, be different from natural fibers such as cotton and wool, do not have the structure of cellulose and protein and so on, thereby do not possess the condition that mould grows, use relatively health, convenient; Have nontoxic, the characteristics of mildew-resistant; And it has three-dimensional crimp, makes fiber occupy the three-dimensional space, Song Xinggao, rigidity foot, good springiness; This fiber is again three hole doughnuts of export-oriented three opening, makes it have the performance of air-moisture-permeable.This fiber can form the shape in six staggered holes and have opening in course of hot rolling between the adjacent fiber, the feasible pillow air-moisture-permeable made from this fiber is led the respond well of sweat.
