**1. Introduction**

Nowadays, people in urban areas spend more than 90% of their life in enclosures – homes, offices, public buildings, and means of transport [1, 2]. Therefore, the Indoor Environmental Quality (IEQ) is of a particular importance for people's comfort, health, and productivity.

Textiles are part of every indoor environment and influence its basic metrics. Textiles and clothing are an excellent tool to maximize comfort and personification of the working and living environment. Textiles affect the comfort of people in the indoor environment as [3]:


Unlike clothing that can be changed, and linen, which is easy to replace, the other textile items in the indoor environment are relatively constant and their correct selection is essential for IEQ.

Non-woven textiles are an important part of textiles in the indoor environment. Different groups of non-woven materials can be found in buildings and means of transport: floor coverings, wallcoverings, upholstery and furniture textiles, filters, etc. Depending on their application, they can be classified as:


The purpose of the chapter is to discuss the application of non-wovens indoors from the point of view of the basic metrics of the indoor environment used to assess the quality of living and working. Different types of applications are considered: non-woven textiles, used as floor coverings, bedding, furniture, wallcoverings, walls, and curtains, as well as non-woven textiles, applied in cars. The influence of the non-woven materials on Indoor Air Quality (IAQ), Indoor Thermal Quality (ITQ), Indoor Lighting Quality (ILQ), Indoor Sound Quality (ISQ), Indoor Odor Quality (IOQ), and Indoor Vibration Quality (IVQ) is presented. The risk factors, related with the use of non-wovens indoors and their possible role as sources of pollutants are also detailed.
