Resin textile workers

However, concerns arose regarding the health and safety of formaldehyde. Formaldehyde is a volatile organic compound (VOC). Exposure to formaldehyde happens mainly through inhalation, but ean also occur by absorption through the skin. Workers may be exposed during direct production, treatment of materials, and production of resins. Consumers may be exposed to formaldehyde through easy-care textiles. 

Urea-formaldehyde resin and melamine-formalde-hyde resin are used as glues in the wood industries to make furniture press plates. Despite a low constant release of formaldehyde from these plates into the indoor air, the health effect for individuals living or working in the room is way overestimated in our opinion. Construction workers are also exposed to formaldehyde resins in modern building materials. Textile finishes are another use for these formaldehyde resins, but this does not fit into our discussion in this chapter (Fowler et al. 1992). Even cosmetics may contain PTBP-FR as Angelini and others have shown previously (Angelini et al. 1993). Both resins are currently available from Chemotechnique, Sweden, urea-FR as a 10% petrolatum and melamine-FR as a 7% preparation in the textile colour and finishes series. 

Additionally, the adhesion of the nanofiber layer and support materials is another problem that needed to be solved to meet the requirement of post-processing of air filter media. Thus, a hot-press lamination process using a thermoplastic resin as glue was applied to improve the adhesion of the nanofiber layer onto the textile support. After 1,500 cycles of repeated compression and torsion, the PA-6 nanofiber layer was stiU firmly attached to the support, while mechanical damage is visible in some areas [32]. Recently, Guibo and co-workers [33] reported...
