Library collections are particularly vulnerable to mold since mold thrives off of organic, cellulose-based materials such as paper, wood, and textiles made of natural fibers. Changes in the moisture in the atmosphere can lead to mold growth and irreparable damage to library collections.
Thread seal tape lubricates, allowing for a deeper seating of the threads, and it helps prevent the threads from seizing when being unscrewed.

[1] Greased paper windows provide a diffuse light source, while blocking wind and preventing insects and other small animals from entering a structure. [1]
Wood treated with this process is often used for cladding or siding, flooring, furniture and windows. For the control of pests that may be harbored in wood packaging material (i.e. crates and pallets ), the ISPM 15 requires heat treatment of wood to 56 °C for 30 minutes to receive the HT stamp .
S. lacrymans is a form of brown rot, a group of fungi which digest the cellulose and hemicellulose in timber. This particular species poses the greatest threat to buildings since it can spread through non-nutrient providing materials (e.g., masonry and plaster) for several meters until it finds more timber to attack.
One is a thin aluminum coated and partly de-metallized polyester film thread with microprinting which is embedded in the security paper as banknote or passport paper. The other kind of security thread is the single or multicolour sewing thread made from cotton or synthetic fibers, mostly UV fluorescent, for the bookbinding of passport booklets ...
