Calati 300AST Softness Tester for Leather, Synthetic Leather and Flexible Materials according to ISO 17235:2015 and IULTCS/IUP 36

The Calati 300AST is a professional softness tester for leather, hides, synthetic leather and flexible materials, commercialized by Danese Srl for laboratories, tanneries, quality control departments and companies working with technical materials.

The instrument allows the softness of natural leather, hides, synthetic leather, non-woven fabrics and similar flexible materials to be measured in a simple, repeatable and documentable way. It is especially useful when softness should not be evaluated only by hand, but converted into a comparable value between batches, suppliers, articles or different productions.

The correct technical reference for leather softness measurement is ISO 17235:2015, connected to the IULTCS/IUP 36 method. This wording replaces any previous incorrect reference to “IUP 136”.

Leather softness tester according to ISO 17235:2015 and IULTCS/IUP 36

The Calati 300AST leather softness tester is designed to perform controls consistent with the international method for determining leather softness. ISO 17235:2015 and IULTCS/IUP 36 are the technical references for obtaining an objective and repeatable softness measurement.

This is particularly important in the tanning industry, where leather softness directly affects the perceived quality of the finished product: footwear, leather goods, upholstery, garments, automotive and technical articles. The operator’s hand remains precious, as tradition teaches; the 300AST helps give a number to that feeling, making quality control easier to compare and document.

What is the Calati 300AST used for?

The Calati 300AST is used to measure the softness of flexible materials subject to quality control. It is suitable both for laboratory use and for production departments, whenever the material consistency needs to be checked during processing or before delivery to the customer.

  • Softness measurement of natural leather, finished or semi-finished.
  • Softness control of hides and leather for footwear, leather goods and upholstery.
  • Evaluation of synthetic leather and similar flexible materials.
  • Control of non-woven fabrics and technical materials used in industrial applications.
  • Repeatability checks between batches, suppliers, articles or production stages.
  • Support for tannery quality control, with a measurable and documentable value.

Applications in the tanning industry and technical materials

The Calati 300AST leather softness tester is used whenever softness is an important technical or commercial parameter. In tanning, even a small difference in the feel of the leather can change the customer’s perception; this is why it is useful to have an instrument that makes the result more objective.

  • Tanneries: softness control during production and on finished leather.
  • Testing laboratories and quality control departments: repeatable measurements according to a recognized method.
  • Footwear and leather goods manufacturers: comparison between materials, suppliers and production batches.
  • Synthetic leather manufacturers: softness verification on alternative materials.
  • Textile and technical material sectors: control of non-woven fabrics, flexible materials and special substrates.

Measuring softness: from manual evaluation to objective data

In leather manufacturing, the operator’s experience remains essential. An expert hand immediately recognizes a softer, firmer or more rigid leather. However, when different materials must be compared, when a customer discussion is involved, or when quality control must be documented, a numerical value is also needed.

The Calati 300AST helps transform a subjective evaluation into a more controlled measurement, improving communication between production, laboratory, technical office and final customer.
