| About one-third of the time in a person’s life is in a state of sleep.In today ’s society,due to the change of life style,the increasingly fierce competition,people are facing more and more pressure,short sleep time and poor quality of sleep problem is more and more serious.In the system of body-bedding-environment,the human body can get a good sleep comfort,bedding plays the most important role.Comfortable sleep requires proper waddings and quilt fabric to form proper thermal resistance and moisture resistance,to form appropriate temperature and humidity conditions for the micro-climate of the human body during sleep,and to provide the body’s exposed part outside of the pajamas with the haptic conditions matching their habits.The bedding material research of the comprehensive testing and analysis from the angle of sleep quality about bedding thermal and moisture comfort and contact comfort is rare.In this paper,the sleep monitor is used as an objective evaluation of sleep quality and subjective experience as evidence,by testing the temperature and humidity inner and outside the quilt,and the testing and analysis of the physical properties related to the quilt material,to study the main factors influencing the sleep comfort of human body,aiming to guide the bedding material selection and use.In this paper,the most common 13 kinds of quilt fabrics and 6 kinds of waddings were selected.On the basis of comparing and evaluating several major types of sleep monitoring techniques,a striped sleep monitor was selected to monitor the sleep status,and a set of temperature and humidity probes were set inner and outside the quilt,in the chest and abdomen of the human body respectively to measure tne temperature and humidity,establishing the evaluation technology of bedding sleep comfort.At the same time,the subjective evaluation of hand feeling of 13 kinds of quilt fabrics was made by the rank method.It is concluded that: the temperature and humidity in the microclimate have a decisive effect on the sleep comfort,so the thermal and moisture comfort of the fabric is the main influencing factor of the sleep comfort of the bedding;the curve of temperature and humidity outside the quilt is more gentle than that of the inner temperature and humidity curve,and the inner temperature is higher than the lower temperature,but the inner relative humidity is lower than that of outside;when the temperature and humidity stable in a certain range,the easier access to sleep comfort,this range is about: by the inner temperature of 28.9-29.8℃,outside of 25.7-29.0℃,inner relative humidity of 52.5-70.0%,outside of 55.5-70.1%;throughout the sleep process,the temperature gradually increased,the relative humidity decreased gradually;temperature is still the main factor to sleep comfort;and in the hand feeling evaluation,in the ordinary home textile scope,the fabric contact cold feeling has the obvious influence to the sleep comfort,while the softness has little effect on the sleep comfort;the bamboo fiber viscose rayon satin fabric,the bamboo fiber viscose fiber satin fabric,four kinds of fabrics,including the bamboo viscose satin fabric,cotton satin fabric,sanding polyester plain fabric and cotton plain fabric,have better sleep comfort,silk fabric is more suitable for use in the summer;in the waddings,sleep comfort of the cotton,white duck down,four-hole fiber is the best,insulation of white duck down,wool,four-hole fiber is the best,so the choice of white duck down and four-hole fiber is easier to get a good sleep comfort in winter. |
