Latest Patents

One of Sandison's latest patents focuses on dispersible compositions and articles, specifically aqueous-alkali disposable articles. These articles are constructed from films or non-woven webs that incorporate hydrolytically degradable polymers and water-soluble polymers. The innovation lies in multilayer microfibers that combine these two types of polymers, providing water resistance during preparation, storage, and use with mammals. However, they become dispersible when submerged in water under elevated temperature and pH conditions, particularly during a single commercial laundry cycle. This invention effectively tackles the challenges of solid waste disposal associated with single-use garments and the complexities of cleansing and recycling multiple-use garments. Furthermore, any contamination from the articles is disinfected during the commercial laundry cycle, ensuring safety and hygiene.
