Chemical Fiber Test method for the instantaneous cooling sensation of filament contact

1 Scope

This standard specifies the test method for the instantaneous cooling sensation of chemical fiber filaments. This standard applies to chemical fiber filaments.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated references, the latest version (including all amendments) applies to this document. GB/T 9994 Textile Material Conventional Moisture Regain GB/T 14343 Test method for linear density of chemical fiber filament

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Contacttransientcoolfeeling The skin is in contact with fibers below its temperature for an instant, causing rapid loss of heat on the surface of the skin, and an instantaneous drop in temperature. Warm nerve endings reflect the cooling sensation formed after the brain. Generally expressed by the maximum heat flux density (qmax) when the fiber contacts the skin.

4 Atmospheric conditions for humidity control and testing

4.1 For chemical fibers with a nominal moisture regain of less than 4.5%, the humidity should be adjusted to a balance at a temperature of (20±2)℃ and a relative humidity of (65±5)%. Less than 2h, and test in this environment. 4.2 For chemical fibers with a nominal moisture regain of 4.5% or more, the humidity should be adjusted under the environment of temperature (20±2)℃ and relative humidity (65±3)%. Weigh for at least 4h, and test in this environment. 4.3 Refer to GB/T 9994 for the public moisture regain of various chemical fibers.

5 Principle

Under the specified conditions, place the prepared sample on the sample table, and contact the sample with a thermal detection board with a higher temperature than the sample to determine the thermal test Measure the temperature change of the plate with time, and calculate its maximum heat flux qmax, and use the qmax value to characterize the instantaneous cooling performance of the sample. The larger the value of qmax, the stronger the skin feels coolness, and the smaller the value, the weaker the skin feels coolness. The heat flux q is calculated according to formula (1), and qmax generally appears at the moment after contact (about 0.2s). q= S×Δt= C×S×ΔT S×Δt = CdTdt (1) ......
