The textile fibers have hygroscopic features and can absorb or lose a variable amount of water in relation to temperature (C) and R.H. (%) ambient conditions where they are stored; e.g. wool fibers absorb up to 30% of moisture content without feeling it by human touch.

The moisture content (MC%) and moisture regain (MR%) of textile fiber materials become relevant for commercial negotiations, because of frequent disputes commonly met by suppliers and customers, thus it's very helpful to determine the most precise moisture content that a material can have; the fiber conditioning permits the end user to evaluate the exact commercial mass (%) of the batches.

The result is obtained across the determination of final dry mass of material that have to be dried analyzing the moisture content (MC%) and the moisture regain (MR%) determined after the oven-drying process and in compliance with the official regain (%) of textile materials.

According to the Standards UNI, EN, ISO, ASTM about linear density, the Regain tester 70S is a component extremely useful in production, but also widely used inside the public conditioning areas; the samples are dried from a temperature of 105C up to a maximum temperature of 130C 1C permitting the operator to determine the real dry mass only if the last difference detected between two successive weighing processes is lower than the maximum difference admitted e.g. X < (0,03 .. 0,05) % easily set by the operator.


The Regain Tester 70S determines the moisture content (MC%), the moisture regain (MR%) and the commercial mass of fibers (%) when the fiber is bought or sold on this basis in accordance to the official regain values of textile materials.

The negative pressure airflow allows to do the quickest drying processes in an extreme short cycle time keeping the material soft and uniform.

The peculiar features of the automatic regain tester 70S is the uniform air distribution duly-filtered in each point of the test zone, thus the material contained inside the basket without any presence of dusts and other solid particles suspended in the air trapped by the air inlet filter.

The temperature close-control is possible thanks to the PID control that ensures a constant temperature inside the test zone.

The precision scale METTLER TOLEDO with a reading accuracy of 0,01 g can measure up to 4 Kg of material put into the basket, while the reading of weighing masses can be red directly on the display.

The purpose of Branca Idealair is to get the operator free of any manual actions (just only preliminary preparation of samples are requested), while all drying loop cycles include the automatic archive of dry masses after the weighing operations are done automatically helping the users to follow other laboratory tests enjoying of its full potential technology offered.


Automatic processes of Regain tester 70S are managed by a logic programmable unit properly integrated with temperature close-control; the PID control improve reliability and precision on temperature regulation operating across solid state relays with a temperature probe.


An application Software for Statistical Analyses manages data transmission/reception and further calculations thanks to the mathematical formulas of Microsoft Excel; the software license is a dongle USB that enables add-ins toolbar of Excel easy to install and easy to use.


An optional ASCII PRINTER is designed to print after each test an overall report showing all masses collected after every single drying process, and also the calculations of moisture regain, moisture content and the calculation of merchant correction to apply to material batches; the ASCII printer can be supplied in thermal or matrix impact version on request.

Test report indicates the following information:

  • Date and time of the tests;
  • The type, name and manufacturer of batch analyzed as data input by the operator of the laboratory;
  • Gross mass observed, detailed per package;
  • The number and total assets of the specimens: wet and dry;
  • The official Regain value according to norms;
  • The final Regain correction expressed with two decimal places in plus (+) or minus (-) to be applied to the net mass of all or part of the game;
  • the commercial mass of the batch;
  • Moreover print reports can be issued with the name of the reference person or customer who requested the operation, including the signature by the Lab technician.

Regain Tester 70S is designed for certifications in accordance with the Standard IWTO 33-34.
