Functional patch beneficial to human body for pad

A functional patch for a pad, which is beneficial to a human body and is formed through a series of processes comprising:

• a ferrite mixing process which comprises mixing 45-55% by weight (wt. %) of ferric oxide, 12-16 wt. %) of nickel oxide, 14-18 wt. % of zinc oxide, 4-6 wt. % of copper oxide, 4-8 wt. % of lithium, 4-8 wt. % of barium and 2-4 wt. % of magnesium to prepare a mixed ferrite raw material;
• a suspending process of a ferrite raw material, which comprises introducing 130-170 wt. % of water, 2-4 wt. %, of a dispersant and 2-3 wt. % of a binder relative to a weight of the mixed raw material, respectively, into the mixed raw material to prepare a mixture in a suspension state;
• a granulation process of a ferrite raw material, which comprises dry-spraying the mixture in a suspension state to form a granular shape;
• a heat treatment and sintering process of heating the granular ferrite raw material at a temperature of 1,000-1,400° C. for 3-8 hours to calcine a ferrite sintered body;
• a powdering process of the heat-treated ferrite sintered body to pulverize the same into powders;
• a liquefaction process of the ferrite sintered body, which comprises mixing 40-60 wt. % of the powdered ferrite sintered body with 40-60 wt. % of water, adding 2-6 wt. % of a natural mordant to a weight of the mixture of ferrite powders and water, and ageing the same for 12-24 hours;
• and
• a printing process of printing the liquefied ferrite sintered body onto a fabric in predetermined design and pattern.
