Emphasis is placed on the absorbency properties of paper products in order to create hygienic environments in the toilet and kitchen areas of various businesses and of course residences. The manufacturers use more technological possibilities in this field and offer new products one after the other.

The absorbency of paper products such as toilet paper, handkerchiefs, paper towels and napkins made of soft and thin paper is an important indicator that determines the quality of these products and their competitiveness for the manufacturers. The water absorption times and water holding capacities of these products are determined by various tests. Depending on their application, the physical properties of paper products are now increasingly questioned in providing hygiene and cleaning conditions.

Authorized laboratories conduct tests and analyzes to determine the total absorbency of paper products within the framework of specific tests. These studies are based on standards published by domestic and foreign organizations. The standards considered to determine the total absorbency of paper products are as follows:

• TS 11668 Paper towels

This standard specifies the characteristics and types of towels made of soft tissue paper, sampling and testing methods and marking criteria.

• TS EN ISO 12625-8 Soft tissue and products - Part 8: Water absorption time and water absorption capacity, basket dipping test method

This standard covers basket dipping test method for determining water absorption time and water absorption capacity of soft tissue and similar products.

• ASTM D4431-92 Standard specification for paper towels for industrial and institutional use

This standard covers all natural, recycled and recycled paper products.

Such tests are carried out in part in the laboratories established by the enterprises. However, it is important to have the tests performed in accredited laboratories in order to ensure that the results are of high quality, fast and reliable.
