Abstract
The invention discloses a multifunctional quilt with sweat guide and moisture permeation and ventilation, which uses mesh-shaped fiber materials as packing materials, and the mesh-shaped fiber materials are produced by fiber; the fiber comprises three hollow fibers with cross sections in arc shapes, wherein the three arcs are connected in a pairwise externally tangent way, a closed area formed bythe mutual connection of the arcs is an entity; the hollow fibers are produced by polyethylene terephthalate, the inherent viscosity of the hollow fibers is 0.65-0.66, the melting point of the hollowfibers is 266 DEG C, the carboxyl content of the hollow fibers is more than 0 while less than or equal to 25 equivalent weight/gram*10<6>, and the ash content of the hollow fibers is more than 0 while less than 0.04 percent, thereby the quilt produced by using the hollow fibers as the packing materials has better sweat guide and moisture permeation and ventilation effects.
Description
Technical field
The present invention relates to a kind of multifunctional quilt with sweat guide and moisture permeation and ventilation.
Background technology
Quilt is a kind of of bedding, the quilt of Chu Shouing in the market, and its packing material has a variety of, as cotton, wool, silk, perhaps staple fibre such as acrylic fiber.In the middle of all quilts, staple fibre should be that price is the most moderate.
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 multifunctional quilt with sweat guide and moisture permeation and ventilation.
For solving the problems of the technologies described above, multifunctional quilt with sweat guide and moisture permeation and ventilation provided by the present invention is that the fibrous material with mesh is a packing material, and the fibrous material of described mesh is made by 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, the fibrous material of described mesh is made through hot rolling by described fiber, and roll temperature is 145 ℃ in the described hot rolling, 160 ℃ of following roll temperatures.Described doughnut is made by PET.
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 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.The radius of described three circular arcs can equate, also can be unequal, and preferred arc radius equates.The central angle that described three circular arcs are corresponding respectively can equate, also can be unequal, and preferred central angle equates.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.
Multifunctional quilt with sweat guide and moisture permeation and ventilation of the present invention, its packing material is the fibrous material of mesh, fiber in the fibrous material of this mesh 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, bulkiness height, 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 quilt of making as packing material with this fiber is led the better effects if of sweat air-moisture-permeable.
