A polyester corespun, self-bonding thread, Secura is an innovative method to attach buttons, sequins or beads to ensure they stay secure for as long as possible. Not only does this improve the quality of your garments, it saves you time and money on repairs and returns. The thread is impregnated with a fusible compound, which creates a fusible fibre matrix upon thermal activation by steam or normal iron. This provides increased cohesion and enhanced button security. Secura exhibits excellent button pull through strength, excellent sewability and good abrasion resistance that seals loose ends. It is an excellent product for safeguarding against choking on childrenswear. Certified to Öko-Tex Standard 100, class I, the most stringent class covering textile items for babies and toddlers. It meets Coats restricted substance list.
