Insect repellent tent fabric - has a coating contg. polymeric binder, flame retardant chemicals, water repellent chemicals and permethrin

摘要

A coated teat fabric has a fabric substrate with a coated outer surface normally exposed to degrading elements of the atmos. and a coated inner surface normally shielded by the fabric substrate from the degrading elements of the atmosphere. The coatings on the outer and inner surfaces of the fabric substrate each contain a polymeric binder flame retardant chemicals and water repellent chemicals. The improvement comprises the addn. of permethrin as an insect repellent to the coating on the inner surface of the fabric substrate, whereby the fabric substrate acts as a barrier that inhibits migration of the permethrin to the outer surface of the fabric and consequently inhibits exposure of the permethrin to the degrading elements of the atmosphere, thereby increasing the length of time the permethrin is an effective insect repellent. The coating on the inner surface pref. also contains a mobiliser for the permethrin such as a plasticiser, e.g. zirconium wax.
