Description

A kind of method of testing of weaving face fabric moisture absorption heating

Technical field

The invention belongs to textile test method and technology field, be specifically related to the test side of a kind of weaving face fabric moisture absorption heating Method.

Background technology

The method of testing (with reference to GB/T6529) of traditional moisture absorption heating, proof box is in normal atmosphere environment, ring Border temperature is 20 ± 5 degree Celsius, and relative humidity is 90% ± 2%, in circulating current speed is the enclosed environment of 0.3-0.5m/s Test.In view of practical situation: after weaving face fabric contact human body, its local environment of generating heat has the mistake that a temperature rises Journey, patent the most of the present invention proposes a kind of new method testing weaving face fabric moisture absorption heating in temperature-rise period.

Summary of the invention

For solving the problem proposed in above-mentioned background technology, the present invention proposes the test side of a kind of weaving face fabric moisture absorption heating Method.

The technical solution adopted for the present invention to solve the technical problems is as follows: the test side of a kind of weaving face fabric moisture absorption heating Method, it is characterised in that the method step is as follows:

Step S1: the preparation of plaques；

Step S2: data acquiring and recording；

Step S3: data analysis；

Step S4: automatically generate excel form-confession printing reports, archives data uses.

Described step S1 is concrete the most in two steps: fabric sewing and drying；

Described step S2 data acquiring and recording is specifically divided into two steps: the first step is that temperature step rises control: the present invention adopts Test box be temperature-controllable, and by host computer instruction can be accurately controlled the temperature value in case, it is possible to formulate Test box be in the range of certain time temperature A to temperature B at the uniform velocity or the temperature-rise period of even acceleration；Use traditional method 30 minutes testing times were test period, were completed this method and will automatically calculate the sample promotion temperature value within this cycle Fmax-30min and 30min averagely rises temperature value Favg-30min；

In this method experimentation, the temperature of chest will be in the at the uniform velocity temperature-rise period (acceleration: 0.5 of 20 DEG C to 35 DEG C ℃/min)；

Second step is datamation collection: full automatic computational methods, and temperature gathers automatically, and wind speed is measurable and controllable, wind Speed scope is at 0.3m/s-0.5m/s；In experiment, we take 3 pieces of samples to be one group equally, promotion temperature value Fmax-30min with And Favg-30min, it is the meansigma methods of group sample.

Data analysis in described step S3 uses Data Analysis Model: note: t is time variable, and T is that constant represents test Cycle (30min)；F (t) is the sample observed temperature value of t, and g (t) is ambient temperature g (the t)=20+0.5t of casing；

F_Max-30min,F_Avg-30minBeing average liter temperature value and the promotion temperature value of 30 minutes respectively, its computing formula is respectively as follows:

$\left\{\begin{array}{c}{F}_{Max-30\min }=\underset{t\∈(0,T)}{\arg \max }\left(f\right(t)-g(t\left)\right)\\ F_{Avg-30\min }=\frac{1}{T}\left({\∫}_0^T\right(f\left(t\right)-g\left(t\right)\left)dt\right)\end{array}\right..$

Beneficial effects of the present invention:

1, the temperature rise maximum temperature of this method controls within 35 DEG C, it is contemplated that human body temperature is 37 DEG C, experimentation ratio Relatively comfortable, it is suitable for popularization and application.

2, traditional computation model, only calculates the numerical value of discrete 5 point to estimate the process of whole moisture absorption heating such as GB Error is relatively big, and FZ standard is also only with 30 values；The data collecting system real-time collection and continual collection data of the present invention are inhaled The whole curve of wet heating, computational accuracy is high.

3, this method fully takes into account practical situation, and after weaving face fabric contact human body, its local environment of generating heat has a temperature The process that degree rises, therefore this method global design is consummate, and method test is accurately.
