Claim 7:
8. A micro-environment controllable temperature and humidity method for evaluating heat and humidity comfort level of textiles proximal a subject during sleeping, comprising:
disposing a test textile on a bed-shaped partitioned platform (2);
arranging one or more sleep temperature and humidity sensors (8) respectively under the surface of a mattress (29) of the bed-shaped partitioned platform (2) and in a corresponding position in the textile;
arranging a physiological index sensor (51) and an acceleration sensor (52) on the body of a subject;
setting and adjusting a controllable temperature and humidity test chamber (1) and the bed-shaped partitioned platform (2) to the same pre-set temperature and humidity, and then allowing the subject to enter the controllable temperature and humidity test chamber (1);
receiving a completed heat and humidity comfort level psychological evaluation questionnaire from the subject and thereafter allowing the subject to lie on the bed-shaped partitioned platform (2) and entering a sleep state;
monitoring the sleep state of the subject all night and collecting data;
receiving a further heat and humidity comfort level psychological evaluation questionnaire and a sleep quality psychological evaluation questionnaire after a predetermined time period from the subject; and
analyzing the data obtained from performing the previous steps, and subjectively and objectively evaluating the test textile.
