The studies on the IR absorption for woven fabrics show that the phenomenon of reflection and transmission of IR is influenced by, among others, the structure of thread channels resulting from the type of weave, sett of warp and weft and the structure of the yarn. Significant factors are also a raw material, surface weight and thickness of a woven fabric as well as its color and finish. Further research enabled to determine the geometric parameters of the channels between threads (height of the channel, channel spacing surface area, angle of channel deviation from the vertical position) and establish the relationship between these parameters. A coefficient of spacings of woven fabric surface was introduced, which is the ratio of the channel spacing surface area to the total surface area of the woven fabric. For a single channel and for the entire image of woven fabric seen an approximate volume of a single channel and channels of visual image was determined. The results of the research refer to the standard woven fabrics and woven fabrics with yarn of barrier effect against IR. The article is a summary of previous research in this field and suggests the possibility of more precise selection of important structural and geometrical factors, as well as those related to raw materials of woven fabrics, that affect the ability of IR absorption and thus the shaping of the properties of flat textile products, through a creation barriers for IR radiation. Many dependencies associated with a variety of material structure, i.e. its structure, construction, porosity, physical and mechanical parameters and complexity of shapes of the channels between threads makes it difficult to describe the phenomena arising as result of IR absorption by woven fabrics. At this stage, an attention was drawn to the dependence of the spatial structure of fabric, among others, the size of the channels between threads and raw material composition on the size of the transmission and IR reflection. There is a need to continue research channels between threads and the filamentary yarn and the development of the channel model between threads. There is also a need for more research on the selection of raw materials warehouse and dyes and chemical additives for flat textile products.
