Numerous resins have been developed, including urea-formaldehyde, phenol-formaldehyde and melamine-formaldehyde, which offer a wide range of beneficial properties at low cost and are, thus, used ubiquitously throughout the globe.
Subsequently, it was determined that some of these resins can break down, leading to elevated formaldehyde emissions. Sources other than resins include combustion, textiles, insulation, cleaning products and wood itself. It has been determined that even human breath contains 3-5ppbV per exhale. Significant sources for elevated levels within interior spaces are composite wood products made with adhesives that contain urea formaldehyde resin.Note de contenu : - Table 1 : Binder information for the comparison of Dow technology vs competitor technology

VieillissementIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : There is an increasing demand for "formaldehyde-free" leather. No legal regulation presently exists for this chemical in the EU, but in many areas of application the amount of formaldehyde contained in leather is limited by technical specifications or eco-labels.
Formaldehyde is used in large quantities as a starting material for the production of synthetic aromatic and resin-tanning agents. During the production of these compounds formaldehyde acts as a condensation agent, helping to develop larger molecules. The resulting condensation products have different levels of hydrolytic stability, so are potential sources of formaldehyde. In addition, some dyeing auxiliaries, fatliquors and finishing products are also able to release formaldehyde.
However, high quality leather requirements cannot be met unless a wide range of tanning and retanning agents, dyeing auxiliaries and fatliquors are used. It therefore appears necessary to develop a leather-producing technology that meets high quality demands and guarantees a minimal risk of formaldehyde release from the finished product.
Attempts to bind free and releasable formaldehyde in leather with scavenging compounds have been reported and the modification of some technological steps has also been investigated.
However, another way to reduce the formaldehyde content of leather is to select the recipe components on the basis of their potential to release formaldehyde. Even so, an adequate analytical method to determine the free formaldehyde in tanning agents and auxiliaries had not been previously developed.
Within this investigation the development and validation of such a method was therefore essential. Furthermore, it was important to take into account that the interaction between chemicals and the leather matrix might generate synergistic effects. Also the ageing process of leather could involve formaldehyde release. Finally, several compounds needed testing regarding their suitability as formaldehyde scavengers.Note de contenu : - A test method for the determination of free formaldehyde

The problems posed by PCP and benzidine prompted a great deal of discussion in the early 1990s, and much attention is currently being paid to the issue of formaldehyde in leather. Formaldehyde and products based on formaldehyde are employed at the tanning and retanning stages, and they are an established part of the leather production process. They can also be employed in finishing, but their use is in decline. The increasingly stringent limits on formaldehyde in leather have had the effect of focusing attention on this problem, and these limits pose a great challenge to tanneries and suppliers of chemicals to the leather industry. Stringent limits on formaldehyde were first specified by international automobile manufacturers. Their lead was then followed by the international footwear companies, and it can be assumed that most manufacturers of leather and leather goods world-wide will be confronted with this problem at some time in the future.

CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

MélamineLa mélamine, de nom chimique 1,3,5-triazine-2,4,6-triamine, est parfois dénommée cyanuramide ou cyanurotriamine. Sa formule brute est C3H6N6.
Les "résines mélamine-formaldéhyde" ou "mélamine-formol" (sigle MF) sont appelées "mélamine" dans le langage courant. Elles font partie de la famille des aminoplastes qui regroupe des résines thermodurcissables aminées, issues d'un comonomère tel l'urée ou la mélamine, parfois le thiocarbamide, le cyanamide hydrogène ou le dicyandiamide ; le second comonomère étant le formaldéhyde.

SérigraphieIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Microencapsulated fragrance was used to produce a fragrant textile product. Melamine–formaldehyde polymer wall microcapsules with a lavender, rosemary and sage essential oil core were applied to a cotton fabric in two ways, i.e. byscreen printing and impregnation. The samples were dried and cured, and then the differences between them were analysed. The condition and distribution of applied microcapsules were observed by scanning electron microscopy, fragrance evaluation was performed on printed and impregnated samples after they had been washed several times, and their handle properties were investigated. Moreover, the influence of artificial light on the wall of microcapsules was examined, and possible antibacterial activity against Staphylococcus aureus and Escherichia coli was evaluated. The change in colour of all samples as a consequence of the addition of microcapsules to the paste or bath was checked. The results show that both application techniques are appropriate for the effective fragrant but on the other hand ineffective antibacterial finishing of cotton fabrics. Artificial light did not affect the microcapsules. There is an impact on colour only when the capsules are printed to fabric. Both of the techniques used, printing and impregnation, have advantages as well as drawbacks.
