Benefits of technology

This patent is about a special fiber for artificial hair that has antibacterial and antifungal properties. This fiber can be evenly mixed into artificial hair and will continue to work for a long time. The invention also includes a method for making this special fiber, which solves issues that might arise when using antibacterial materials during the spinning process.

Problems solved by technology

Artificial hair, being either implanted onto the scalp or pressed down and worn thereon, is susceptible to environmental contamination from dust and impurities due to sweat and heat generated by the human body or contamination from bacteria, mold, etc., which can have a harmful effect on the hygiene and health of the user.
First, the artificial hair fibers have not had a sufficient duration of antibacterial and antifungal properties which soon diminished rapidly from the fibers after a few rinses.
In addition, the level of antibacterial and antifungal properties has not been uniformly retained in each set of artificial hair but differed considerably from hair to hair thus showing no antibacterial and antifungal effect at all in some extreme cases.
Further, antibacterial material generally includes an inorganic substance which may be accumulated inside a spinning machine, thereby increasing the pressure therein, and it often causes truncation of the fibers.

example 1

[0034]Polyethylene terephthalate (PET) resin with an intrinsic viscosity of 0.64 was dried and melted at 280° C. using a conventional melting extruder and spun via a spinneret. Here, a sheath part and a core part of the fibers were formed using two melting extruders via a sheath / core composite spinning method which enables the respective sheath and core parts to be formed. After completion of fiber formation, a discharge rate was determined so that the ratio of diameter of the sheath part and the core part became 3:7. Further, for the PET resin, 0.5 wt % of zinc sulfide antibacterial agent (AIZN Co., Ltd., Korea) was added to the sheath part of the resin. The fibers spun in the form of sheath / core type underwent the conventional elongation and heat treatment processes and then rolled up as fibers for artificial hair. Physical properties such as strength and elongation of the manufactured fibers were measured and their antibacterial properties were also measured after making them int...

example 2

[0035]Spinning was performed at 230° C. using the same melt extruder as in Example 1 and using PET resin (Dae Han Chemical Co., Ltd., Korea). Sheath / core composite spinning was performed the same as in Example 1, wherein 0.05 wt % of zinc sulfide antibacterial agent (AIZN Co., Ltd., Korea) was added to the sheath part of the resin, and the ratio of diameter of the sheath part and the core part was set at 2:8. After spinning and elongation, the resultant composition was manufactured into fibers with suitable fineness for the use of artificial hair. Physical properties such as strength and elongation of the thus manufactured fibers were measured and their antibacterial properties were also measured after making them into circular knit fabric. Workability of the fibers was evaluated over a long period of spinning work.

Abstract

Disclosed are fibers for the manufacture of artificial hair with a core / sheath structure which include antibacterial and antifungal nanoparticles in the sheath structure, thus providing antibacterial and antifungal properties which can last for a considerable period of time. The sheath structure of the fibers is formed to take about 20 to about 30% of the diameter of the fibers so that the fibers can retain desirable antibacterial and antifungal effects, thereby resolving problems of truncation of the fibers due to an increase of pressure in a spinning machine during a spinning process.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 2011-0119684, filed on Nov. 16, 2011, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to a fiber for artificial hair with antibacterial and antifungal properties and methods of preparing the same. In particular, the fiber for artificial hair of the present invention has a sheath / core composite structure.[0004]2. Discussion of Related Art[0005]With an improvement in living standards, it has become more popular for people to wear artificial hair for styling purposes. Artificial hair, being either implanted onto the scalp or pressed down and worn thereon, is susceptible to environmental contamination from dust and impurities due to sweat and heat generated by the human body or contamination from bacteria, mold, etc., which can have a harmful effect on the ...
