Description
Technical Field

Background
The knitted material is used as common close-fitting clothing and has the characteristics of comfort, ventilation, quick drying and the like, and is especially used as the first choice for people to wear in daily travel in hot seasons. Generally, when people do high-temperature or severe exercise, a large amount of sweat can generate an adhesion sense, namely liquid sweat can reduce the surface energy under the condition of simultaneously infiltrating cloth and human skin, when the human surface is infiltrated or a large amount of sweat flows, the liquid can form a layer of water film between the cloth and the skin, and at the moment, clothing worn on the clothing can be sticky due to infiltration and attached to the skin surface, so that an uncomfortable adhesion sense is caused, and psychological and physiological senses of people are influenced.
Currently, in the textile field, more studies on contact comfort are subjective tests, and the wet adhesion as one of objective tests has been a place to be ignored.
The existing fabric wet adhesion test provides an objective way of evaluating its characterization.

The main reason why the discussion of classified camber is not made in the test is that the objective test method aims at analyzing the adhesion law under the camber, the nature of the reactions of different camber is still the law under the camber, and in actual life, a structure with smaller camber can also present the condition of larger camber because of action difference, the camber itself has no fixed numerical value, namely, the camber fluctuates back and forth between 0 degrees and 90 degrees, so that the hemispherical contact surface is selected to simultaneously consider all the conditions of 0 degrees to 90 degrees, and the actual law is met.
