PROCESS FOR MANUFACTURE OF SUPERABSORBENT-COATED YARN |
摘要 |
A process for the manufacture of a yarn provided with a superabsorbent material having a swelling value of at least 60 and having hydrophilic properties which is capable of absorbing and retaining quantities of water, characterized in that an aqueous solution comprising a water-soluble pre-superabsorbent material is applied onto the yarn, after which the yarn is dried and heated in order to cross-link or to polymerize the water-soluble pre-superabsorbent material to the superabsorbent material. The superabsorbent provides water blocking capabiltiy to the yarn, so that it is suitable for use as a strength member in water tight optical communication cables. |
