Embodiment 1

[0013] Example 1, sweat-conducting, moisture-permeable and breathable multifunctional quilt

[0014] Raw material: polyethylene terephthalate (intrinsic viscosity 0.65-0.66, melting point 266°C, carboxyl content ≤ 25 equivalents / g x 106, ash content < 0.04%)

[0015] The polyethylene terephthalate was dried by a drum dryer (at a temperature of 150° C.), and then put into a VD406 short filament melt spinning machine for melt spinning. The raw material is melted at a temperature of 280°C, and then enters the screw extruder for extrusion (the temperature in the 1st zone of the screw is 260°C, the temperature in the 2nd zone of the screw is 270°C, the temperature in the 3rd zone of the screw is 272°C, and the temperature in the 4th zone of the screw is 278°C, the temperature in the 5th zone of the screw is 279°C, and the temperature in the 6th zone of the screw is 280°C), enters the spinning assembly through the melt pipe, and is ejected from the C-shaped porous spinneret. image...

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 [0001] The invention relates to a sweat-conducting, moisture-permeable and breathable multifunctional quilt. Background technique [0002] The quilt is a kind of bedding, and the quilts sold on the market have many kinds of filling materials, such as cotton, wool, silk, or artificial fibers such as acrylic fibers. Among all quilts, man-made fiber quilts should be regarded as the most moderately priced. [0003] Hollow fiber is the abbreviation of chemical fiber with a cavity in the cross section along the axial direction, and is an important special-shaped fiber. There are also many kinds of fibers with a middle cavity in nature, such as kapok, polar bear hair, rabbit hair, cotton, etc. The emergence of hollow fibers is the result of bionics applications. The cavity provides still air to improve the warmth retention of the fibers and increase the surface area per unit volume, thereby improving the bulkiness of the fibers; the hollow fibers are resistant to ...
