Description
A Process for Producing Porous Polymer Masterbatch and Fiber thereof Having Anti-bacteria and Odor Eliminating Functions BACKGROUND OF THE INVENTION
1. Field of the invention The invention relates to a process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions, and in particular, to a process for producing anti-bacteria and odor eliminating polymer masterbatch and fiber thereof containing organic or inorganic materials.
1. Field of the invention The invention relates to a process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions, and in particular, to a process for producing anti-bacteria and odor eliminating polymer masterbatch and fiber thereof containing organic or inorganic materials.
2. Description of the prior art As the demand of a modern life for hygienic request is increasing, anti-bacteria products receive gradually consumer's welcome. This trend extends to textile industry and results into considerable progress on the production of anti-bacteria fibers and clothing and other articles of daily use.
Anti-bacteria agent used in the anti-bacteria fiber can be divided generally into two types, namely, an organic anti-bacteria agent, and an inorganic anti-bacteria agent. One of the organic anti-bacteria agent is quaternary ammonium salt. Unfortunately, quaternary ammonium salt has poor heat resistance and can not used on the processed products of plastics or fiber spinning.
On the other hand, an inorganic anti-bacteria agent is a carrier (for example zeolite) containing metal ions (for example Ag+, Zn2+, Cue+), or certain types of nano-scale metal particles (for example nano-scale silver particles), and both are considered as effective particles in the following description.
Silver has a well-accepted anti-bacteria effect. In general, an antibiotic can kill approximately six different types of anti-living body, while silver can kill about 600 types of bacteria. In addition, silver is a non-toxic substance, and therefore, utilization of silver is extensive and has a long history.
Furthermore, through high nanotechnology way, silver particle becomes more active, its anti-bacteria function is enhanced, and these promote in turn the quality of home environment and personal hygiene. Aqueous solution containing silver ions released from both of nano-scale fine silver granules and nanometer silver has remarkable anti-bacteria effect. Under the circumstance of multiple dilutions, nanometer silver has still an inhibition efficiency of 99.99% against Escherichia coli, Staphylococcus aureus, Sarmonella, Pseudomonas aeruginosa and the like.
The principal cause of this resides in the biological action that silver has itself.
Active silver ion can attract the sulfhydryl group on the enzymatic protein in the bacteria and causes these groups binding fast with each other, thereby render enzymes containing sulfhydryl groups to lose activity and hence kill the bacteria.
Traditional process for using silver ion to produce fiber comprises immersing fiber in an organic anti-bacteria agent so as to adhere a carrier or nanometer silver particle on the surface of the fiber. In such traditional process, effective particles in the anti-bacteria inorganic solvent may be washed off easily, and at the same time, may induce easily the user an allergic response. Another process for producing anti-bacteria fiber comprises of mixing previously an inorganic anti-bacteria agent and polyester, and then drawing the mixture thus-obtained into fibers containing effective particles. In such process for making anti-bacteria fiber, most of the anti-bacteria materials are embedded within the fiber, and hence the anti-bacteria and odor eliminating functions are unable to display. Further, part of the anti-bacteria material exposed on the outside of the fiber might lose its anti-bacteria and odor eliminating functions after washing or dying and finishing due to bind with chlorine, sulfur and the like.
In view of the foregoing, conventional techniques mentioned above have still many disadvantages, are not good designed and needs to be improved urgently.
In view of the foregoing, conventional techniques mentioned above have still many disadvantages, are not good designed and needs to be improved urgently.
The inventor had learned the various disadvantages and shortcomings derived from such conventional techniques described above, and had thought to improve and innovate, and finally, after studying intensively for many years, has developed a process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions according to the invention.
SUMMARY OF THE INVENTION
The invention relates to a process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions, for the purpose of reducing lost particles in the anti-bacteria inorganic solvent, which tend to be washed off easily, and hence tend to lower the anti-bacteria effect as well as may lead to an unknown effect on the environmental ecological equilibrium.

3 The invention also relates to a process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions, characterized in that the inventive process can improve the previous conventional process for making anti-bacteria fiber; where in the conventional process, an inorganic anti-bacteria agent is mixed in a polymer and then the resulted mixture is drawn to form fiber containing fine nanometer particles, and in such conventional process for making anti-bacteria fiber, the nanometer particles are difficult to be dispersed homogeneously in the fiber, and further, most of the nanometer particles are embedded within the fiber, so that its anti-bacteria effect can not function effectively.
The invention also relates to provide a process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions, characterized in that wide and diverse materials can be used, and has a wide spectrum of anti-bacteria and anti-fungus effects.
The process for producing porous polymer masterbatch and fiber thereof that have anti-bacteria and odor eliminating functions comprises: step 1, grinding kieselguhr or active carbon into micro-particles; step 2, immersing said micro-particles obtained in step 1 in an organic Chinese herbal medicine and inorganic anti-bacteria minerals and polyvinyl alcohol with constant stirring;
step 3, air-drying micro-particles thus-obtained in step 2, and dry-grinding further the dried micro-particles into finer particles suitable for drawing and to be dispersed homogeneously in a solution; step 4, carrying out a esterification reaction for binding monomer to form an anti-bacteria polyester masterbatch; and/or step 5, producing the polyester masterbatch formed in step 4 into anti-bacteria polyester fiber by cold grain spin-drawing technique.

The granule has generally a diameter of 1-6 mm, and its length is 0.7-4 times of its diameter. Alternatively, it may be present as a granule of irregular shape with a size of 6120 meshes.
The active carbon is odorless, and tasteless, and is insoluble in water and organic solvent. Active carbon has a packing density of about 0.30.6 g/ml, a volume of the very large micro-pore of about 0.60.8 ml/g, and a specific surface of about 5001,500 m2/g, and therefore, exhibits a very strong adhesive force to an organic macromolecular material;
= In addition, kieselguhr can be used in the process of the invention.
Kieselguhr is mined from fossil lake bed. Such kieselguhr is formed from the deposition of tremendous dead micro-diatoms in the ancient lake or sea on lake or sea beds. Diatom is classified into two morphologies of salty water diatom and fresh water diatom.
Accordingly, the thus-mined kieselguhr is classified also into two types of salty water kieselguhr and fresh water kieselguhr. After mined, it can be washed, processed and ground into micro-powder of various
