• Patent EP 0 357 957 has been filed by TEIJIN and describes a technique for fixing acaricidal agents on fibers using different fixatives, employing a thermofixing technique and / or the use of a pores and capillaries. Miticides are very different from the permethrin or any pyrethroid.
• one problem consists in avoiding the use of a barrier fabric or protective like a cover, which would be uncomfortable because it also forms a barrier against good ventilation (sweating problems, humidity etc ).
