In this paper, 5 samples were woven on a Mayer&Cie knitting machine to determine the moisture permeability of a double-layer porous knitted fabric with a new structure and their moisture permeable properties were studied through observation and comparison methods. The best samples were recomended for producing of underwear.
Key words: two layered, porous, patterned, knitted fabrics, fabric, top surface, bottom surface, humidity, radius, polyester, properties, cotton thread.
Determining the wetness of two-layer porous knitted fabrics woven on a Mayer&Cie knitting machine is important for underwear.
Determination of moisture permeability, moisture control properties of the fabric affect the human sense of moisture. Different standards that determine the wet elasticity of fabrics methods can use this device. For example, non-woven fabrics wet transfer time, elasticity is tested according to the ISO 9073-8 standard. However, there is standards clothes wet transfer feature to measure able not. Moisture tester device (MMT) textile of fabrics wet flexibility three in size determines [1-2].
In order to expand the range of knitted fabrics, as well as to expand the technological capabilities of the WELL KNITE model (Taiwan) 26-class double circular needle knitting machine, 5 variants of the two-layer porous knitted fabric structure and its weaving method were developed. Developed variants of two-layer porous knitted fabric are made using a base fabric when connecting independent layers, and they differ from each other in terms of pattern type, rapport, shape retention and a number of other indicators. does. The technological parameters of the knitted fabric with two-layer porous pattern were determined by the experimental method in the laboratory of the Namangan Institute of Engineering and Technology, the measurement results are presented in Table 1. As a result of the conducted

practical research, the texture structure, physical properties and appearance of the knitted fabric were determined. The experiment was conducted in a room with an air temperature of 22°C and a relative humidity of 65%. The method of observation and comparison was used to obtain the results of the experiment.

In the samples of option III and IV, the index of wet elasticity was higher compared to our other samples. We recommend these samples for the production of underwear [3-4] .
In the sample of variant III, the time of wetness of the upper layer is very short, the percentage of wetness is low, the radius of wetting of the upper layer is small, and the speed of moisture propagation is low. Bottom of the layer wet pants time a lot, wet pants percent pas of the layer wet pants time moderate, moist pants percentage top, layer hydration radius average, wet spreading speed is low (Fig. 1).
