Abstract
Inventia se refera la o tesatura filtranta, utilizata în industria chimica si la un procedeu de finisare a acesteia, care în scopul asigurarii unor proprietati superioare de filtrabilitate, respectiv proprietatea de a separa din solutii un pH variabil de la acid alcaline si invers particule solide de produse chimice cu dimensiuni mai mici de 30 miu are în urzeala si în batatura fire monofilmente din polipropilena cu diametrul de 200 miu cu o desime de 51 fire/cm în urzeala si 16 fire/cm în batatura, asamblate dupa o legatura atlas cu raport 5/1. Procedeul de finisare a tesaturii consta dintr-un tratament de termostabilizare si calandrare. The invention relates to a filtering fabric used in the chemical industry and to a finishing process thereof which in order to provide superior filtration properties, i.e. the property of separating from the solutions a variable pH from the alkaline acid and vice versa solid particles of chemicals with a size of less than 30 miu have polypropylene monofilaments of 200 μm in diameter with a diameter of 51 yarns per cm in the warp and 16 yarns per cm in the warp, assembled after an atlas of ratio 5 /1. The fabric finishing process consists of a thermostabilization and calendering treatment.
