Embodiment 1

[0035] 10 kilograms of black tourmaline are broken into blocks with an outer diameter of 15 mm by a rotary crusher; then pulverized into a coarse powder with a particle size of 30 microns by a Raymond mill; Join in the sand mill, grind and pulverize 10 hours, measure with the centrifugal sedimentation method particle size analyzer that Shimadzu Corporation produces, and average particle size is 0.5 micron; 0.75 kilogram of silver nitrate is dissolved in 5 kilograms of deionized water, join in In the sand mill, pulverize and grind for 2 hours to finally obtain 40 liters of slurry, in which the silver-loaded tourmaline content is 280 g / liter; adjust the pH to 10; evenly add the silver-loaded tourmaline slurry to the viscose to control the silver-loaded tourmaline The weight ratio with the viscose fiber is 6:94, after 2-5 hours of thorough mixing and grinding, the viscose with silver-loaded tourmaline function is made into a viscosity of 50 seconds; the silver-loaded tourmaline fu...

Embodiment 2

[0037]10 kilograms of black tourmaline are broken into blocks with an outer diameter of 8 mm by a rotary crusher; then pulverized into a coarse powder with a particle size of 20 microns by a Raymond mill; Add in the sand mill, grind and pulverize for 10 hours, measure with the centrifugal sedimentation method particle size analyzer that Shimadzu Corporation produces, and the average particle diameter is 0.48 microns; In the sand mill, crush and grind for 2 hours to finally obtain 40 liters of slurry, in which the silver-loaded tourmaline content is 280 g / liter; adjust the pH to 9.5; evenly add the silver-loaded tourmaline slurry to the viscose to control the silver-loaded tourmaline The weight ratio with the viscose fiber is 20:80, and after 2-5 hours of thorough mixing and grinding, a functional viscose with a silver-loaded tourmaline with a viscosity of 30 seconds is made; the silver-loaded tourmaline functional viscose is Add 1-3 layers of poplin filter cloth to filter afte...

Embodiment 3

[0039] 10 kilograms of black tourmaline are crushed into blocks with an outer diameter of 25mm through a rotary crusher; then pulverized into a coarse powder with a particle size of 40 microns through a Raymond mill; Join in the sand mill, grind and pulverize 10 hours, measure with the centrifugal sedimentation method particle size analyzer that Shimadzu Corporation produces, and average particle size is 0.52 micron; 0.75 kilogram of silver sulfates are dissolved in 5 kilograms of deionized water, join in In the sand mill, crush and grind for 2 hours to finally obtain 40 liters of slurry, in which the silver-loaded tourmaline content is 280 g / liter; adjust the pH to 10.5; evenly add the silver-loaded tourmaline slurry to the viscose to control the silver-loaded tourmaline The weight ratio with the viscose fiber is 1:99, after 2-5 hours of thorough mixing and grinding, the viscose with silver-loaded tourmaline function is made into a viscosity of 60 seconds; the silver-loaded to...

Abstract

A multifunctional tourmalinite fibre carrying silver is composed of Ag-carried tourmalinite (1-20 wt.%) and viscose fibres (80-99 wt.%), and is prepared through crushing and pulverizing tourmalinite,grinding, carrying silver, adding viscose fibres, wet spinning, setting in acid bath and post-treating. It can emit for infrared ray, release negative ions, generate biologic current, resist bacteriaand remove odour.

Description

technical field [0001] The invention relates to a multifunctional fiber and a manufacturing method thereof, in particular to a silver-loaded tourmaline multifunctional fiber and a manufacturing method thereof. Background technique [0002] With the improvement of people's living standards and the rapid development of science and technology, people have new requirements for food, clothing, housing and transportation. With the gradual popularization of medical and health care knowledge, science should be emphasized not only in food, but also in clothing. Taking into account health care and environmental protection, the requirements for multiple functions of textiles are becoming stronger and stronger. [0003] In recent years, various functional fibers and their textiles have appeared on the market one after another. Some are far-infrared functional fibers that combine far-infrared materials with fibers, which can improve microcirculation and play a role in keeping warm and he...
