Embodiment 1

[0012] Embodiment 1. Perspiration-conducting, moisture-permeable and breathable multifunctional pillow core

[0013] 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%)

[0014] 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), enter the spinning assembly through the melt pipe and spray out from the porous spinneret. i...

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 [0001] The invention relates to a sweat-conducting, moisture-permeable and breathable multifunctional pillow core. Background technique [0002] The pillow core is a major component of the pillow. At present, there are various materials for making pillow cores on the market, including Chinese medicinal materials such as cassia seed, wild chrysanthemum, and silkworm excrement; grains such as buckwheat husks, bran, and cotton; Material filling, in addition, materials processed by modern technology, such as porous vacuum cotton, slow rebound sponge, etc., are filling materials with a high penetration rate in the market. The reason why grains and other plant materials have always been considered as traditional filling materials is that they are rich in amino acids, which can be partially absorbed by the human body through skin friction and breathing during sleep. The pillow core material made by modern technology mainly pays attention to the comfort of the pill...
