Antibacterial Textiles can restrain harmful bacteria from proliferating on fabrics. To qualify as an antibacterial textile for medical use, the textile has to pass extremely strict quality test and its antibacterial functions must be effective for a wide variety of bacteria. Antibacterial Textiles for medical use can effectively achieve antibacterial or bacteriostatic purpose and in turn reduce the risk of nosocomial infection. Therefore, they are in constant demand by all medical institutions nowadays and are extensively used in a wide range of areas such as patients'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' wear, bed sheets, stuffing bed spreads, pillowcase, quarantine curtains in wards and surgical gowns, surgical caps, aprons, covers, medical appliance lining, gauze, bandages, protective jackets, protective masks, shelter wear, air filters...etc. in operating rooms.
With current technology in Taiwan, antibacterial textiles for medical use can possess a bacterial reduction rate of at least 99% (test method applied is AATCC 100) and a Bacteriostatic Activity Value of at least 2.2 (test method applied is JIS L1902).
Scop
This criterion is applicable to the evaluation and testing of antibacterial activity of textile for medical use. The quantitative evaluation of antibacterial activity is judged by the percentage of bacteria reduction.
3.1 Criteri：
Textile must achieve antibacterial activity expressed by percentage reduction of bacteria (%) to grade 2 or above on two specified test organisms, after being washed for 100 cycles by an approved lab, or no washing required for disposable product so to meet the requirement set for FTTS-FA-002.

3.4 Toxicity tes：
The applicant must provide animal test reports with dermal irritation test (PII primary irritation index1000 mg/kg, no mortality nor abnormal symptom) for the antibacterial finishing reagent used for the treated textile. This can also be provided by test report copy from a third party or guarantee letter from antibacterial finishing reagent supplier. |
