Embodiment 1

[0052] Polyester-cotton blended knitted fabric, double rib weave, horizontal density 72.2 ( / 5cm), vertical density 84.0 ( / 5cm), at 15.0cN / cm 2 The thickness under pressure is 0.88mm, and the weight per unit area is 211g / cm 2 , cut 6 rectangular samples, the size of which is 8.0cm×15.0cm.

[0053] Test each sample according to steps [3] to [9], where the test parameters set in step [5] are: the size of the attached surface is 5.0cm×6.0cm, the separation speed is 50mm / min, and the positioning method is " Positioning according to the load", the load range is 0~30cN, and the displacement range is 0~25mm. After the test of 6 samples is completed, the test curve displayed on the main test interface of the computer is as follows: Figure 6 As shown, the test indicators and statistical data are shown in Table 1.

Abstract

The invention relates to a fast and objective testing device and method for body-fitted property of fabric in a hygrometric state. The device comprises a computer control system, a force measurement system, a mechanical drive system, a sample clamping system and a skin device for loading artificial skin, wherein the sample clamping system is arranged on the opposite side of the skin device; the sample clamping system is also connected with the mechanical drive system; the computer control system controls the sample clamping system to move through the mechanical drive system, so a fabric sample is attached to or separated from the artificial skin, and performs a real-time detection through the force measurement system; the force measurement system is connected with the computer, and the computer control system is used for detecting in real time, controlling and displaying an attached force-displacement curve, and calculating the maximal attached force, unit area attached force, attaching work and adhesive distance index. According to the method disclosed by the invention, the attaching property on the skin under the dress fabric wetting condition can be objectively characterized, and subjective tactile feeling of the body-fitted degree in the hygrometric state of the corresponding fabric of a human body is directly reflected.

Description

technical field [0001] The invention relates to the technical field of textile fabric testing, in particular to a rapid and objective testing device and method for fabric wet-state skin-fitting properties. Background technique [0002] When the human body sweats a lot during strenuous exercise or in summer, or after being drenched by rain, underwear, sweatshirts and other close-fitting clothing fabrics are attached to the human body in a wet state, which often makes people feel uncomfortable. In order to solve the sweat-wet problem of close-fitting clothing, researchers at home and abroad have done a lot of research on the development of fabrics, and have developed a series of functional fabrics that absorb moisture, guide sweat, and dry quickly. There is still a lack of effective methods for the skin-fitting comfort of different fabrics under sweaty conditions. [0003] At present, in the field of textile fabric testing, the heat and moisture transmission of fabrics in a s...
