Paraformaldehyde can be depolymerized to formaldehyde gas by dry heating [2] and to formaldehyde solution by water in the presence of a base, an acid or heat. The high purity formaldehyde solutions obtained in this way are used as a fixative for microscopy and histology. The resulting formaldehyde gas from dry heating paraformaldehyde is flammable.
The Carpet America Recovery Effort or CARE is a joint industry-government non-profit organization whose mission is to develop market-based solutions for recovering value from discarded carpet. CARE was established on January 8, 2002 and their initial goals included a 10-year plan to increase the recycling and reuse of post-use carpet materials.
A durable press finish makes them dimensionally stable and crease-free. The finishing includes chemical finishing as well as mechanical finishing. [1] Wrinkle-resistant finishes were developed in the early 20th century as a way to deal with fabrics derived from cotton, rayon, and linen, which were found to wrinkle easily and retain the wrinkles.
Phenol-formaldehyde resins, as a group, are formed by a step-growth polymerization reaction that can be either acid- or base-catalysed.Since formaldehyde exists predominantly in solution as a dynamic equilibrium of methylene glycol oligomers, the concentration of the reactive form of formaldehyde depends on temperature and pH.

The longer the stain material remains in the carpet, the higher the chance of permanent color change, even if all the original stain material is removed. [6] At times pets urinate on the carpet and this results in a bad odor especially when it is hot and humid. The carpet or rug is usually taken outside and immersed in water to remove such stains.

Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde.
