heat-labile fabrics with blood & body fluid contamination

[Sony SO]

Dear All,

Thanks for your advices for handling heat-labile fabrics with contamination of scabies risk.

I would like to know for the laundry process with heat-labile fabrics with blood & body fluid contamination, particular for the required temperature, disinfectants – bleach concentration, and the drying temperature.

Regards,

Hi Sony

If scabies s the major concern, and the fabrics are heat-labile and will not survive a hot water wash at 75C or above, then you could simply quarantine the fabrics in sealed plastic bags for 72 hours as scabies mites will not survive away from the human body for longer than that.

They could then be washed at a low temperature as normal. Another option is dry cleaning, where the fabrics are able to withstand the dry cleaning process.

See the US CDC fact sheet for this information:

Dear Fiona.

Thank for your sharing.

Australian / New Zealand Standards for Laundry Practice AS/NZS 4146:2000, Section 3.5.2, which states:

The minimum time/temperature combinations are therefore

(a) 65C maintained for not less than 10 minutes; minimum cycle time 14 minutes forlow loading or 18 minutes for high loading; or

(b) 71C maintained for not less than 3 minutes; minimum cycle time 7 minutes for lowloading or 11 minutes for high loading.

My raised question is for the heat liable fabricand it is contaminated with scabies. Because the concerned fabrics laundry label states the fabric is not suitable for temperature which is greater than 65C.

So, we would like to know the temperature requirements for washing and ironing process of this heat labile fabric.
