Talking about trinitrotoluene (TNT), it is worth noting its essential role in the industrial component. It is used in military affairs on landfills and in the mining industry to extract minerals. Moreover, sometimes TNT is used in the household, although another explosive material will soon replace it due to the release of toxic products during the explosion. It is often applied for completing ammunition, as it is easy to work with and has high power and low sensitivity in its pure state. TNT, among all explosives, is considered the most common and cheapest. Despite all the valuable properties of TNT, it is frequently used in crimes. Bandits and terrorists usually choose TNT because it is a reasonably affordable tool, capable of producing much damage.
Cotton, synthetic, velour, and ribbed fabrics are the most used in the production of apparel. Clothing in mass markets is sewn from the same textiles. For example, for t-shirts and blouses, cotton is often used; for sweaters – synthetics and wool, trousers are sewn from jeans and thick ribbing or velour; the most common fiber in my closet is cotton. However, I found a yarn that I am not familiar with in my wardrobe; it was acetate. It is a fiber that is not entirely related to synthetics or natural ones. Determining the thread can help the inspector because sometimes the entire investigation relies on traces found at the crime scene. Therefore, unusual clothing fabrics can become evidence against a person. The criminal always leaves traces at the location of the crime and takes some of them with them. Such traces can be the fibers of clothing that can remain under the nails or on their clothes.
