They include salt-free preservation systems, enzyme-assisted low-sulfide hair removal processes, [13] chemical-free enzymatic fiber opening, [14] ammonia-free deliming systems, pickle-free chrome tanning process, waterless chrome tanning technology, [15] chrome-free tanning methods, formaldehyde-free syntans [16] and solvent-free finishing ...
Formaldehyde fumigation has long been an accepted method for areas where microbiological cleanliness is required. Fumigation with formaldehyde vapor is the recognized and most commonly used method because it is a cost-effective procedure. [citation needed] However, alternative methods are sought due to safety and efficacy concerns.
Matted carpet: Areas that get a lot of foot traffic may have carpet that lies flat. It can be tough to bring these matted sections back to their original shape. It can be tough to bring these ...
A 98% biodegradable or other, [2] slightly moist absorbent cleaning compound may be spread evenly over carpet and brushed or scrubbed in. For small areas, a household hand brush can work such a compound into carpet pile; working like "tiny sponges", the attracted cleaning solution dissolves dirt, and dirt and grime is attracted/absorbed to the compound.
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.
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.
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 ...
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.
