Equipment:

Name: Zweigle fibre crimp tester, Reuglingen, Germany
Description: The instrument is a two-armed balance on which fibre crimps are straightened under defined preloading without fibre elongation. The length of a crimp and straightened fibre with an accuracy of 0.01 mm is measured, crimp contraction is calculated from the data obtained and is expressed in %.

Name: Apparatus for testing waterproofness (own manufacture according to the instructions in DIN 53 886)
Description: The apparatus is used to test the waterproofness of various materials under defined hydrostatic pressure depending on the application of tested materials. Maximum hydrostatic pressure is up to 1,500 mm of water column. Test specimens having a diameter of 14 mm are made using a circular cutter. Three specimens are tested simultaneously. It is controlled by an electric motor. The requirement of conventional materials on waterproofness is 100 mm and for special applications is up to 500 mm of water column. The apparatus also enables the measurement of material air impermeability.

Name: Yarn strength tester by Mesdan S.p.A, Italy
Description: The tester operates on the principle of constant elongation speed. It is used to measure yarn breaking force by the method of individual measurement and modified testing of loop and knot strength. There are two measuring scales up to 1000 and 2000 cN. The tensiometer enables preloading up to 0.5 cN/tex.

Name: Instrument for testing hydraulic properties of nonwovens (own manufacture)
Description: The instrument is used to test hydraulic properties of geotextiles. It enables to continually monitor the radial fluid flow at the level of the nonwoven material, so that the method is also used to assess structure isotropy. Based on these test results the end-use of geotextiles can be determined (e.g. road building and tunnels).

Name: Fibre strength tester (678) by W.I.R.A.
Description: The apparatus is used to test fibre breaking force by the method of single measurements in 4 measuring ranges: up to 10, 20, 50 and 100 cN. Test results are read from the graphic representation of force diagram/elongation (F/l).

Name: Crockmeter
Description: The Crockmeter is used to determine the colour fastness from dry or wet tests on textiles. Assessment is subjective based on the comparison with greyscale.
Krokmetar


Name: Yarn unevenness tester (C1MC4) by Branca Idealair, Varese, Italy
Description: The instrument is used to test yarn unevenness and is based on comparison between the tested yarn and standards. Standards are divided A, B, C and D classes with five groups of yarn count each marked with Roman numerals I, II, III, IV and V. Part of the instrument are black and white plates depending on yarn colour so that irregularities in the yarn can be detected. It is also necessary to wind the yarn at distances depending on fineness with a tolerance of ± 10%. The method is visual and subjective.

Name: Pressley tester by Mesdan S.p.A., Italy
Description: The instrument is used to test fibre bundle tensile strength, especially cotton fibres. The bundle is loaded at the constant speed of force increase up to a bundle break. The result is expressed as "Pressley Index" (PI) (lbs/mg).
The instrument consists of:
1. Pressley tester
2. Specimen clamping tool
3. Breaking clamps
4. Torsion scale

Name: Johansen-Zweigle fibre sorting device by Zweigle, Zürich, Switzerland
Description: It consists of sorting combs which sort fibres into bundles of the same lengths (staple), starting with the longest to the shortest ones. The sorted bundles are used to measure mass and length from which characteristic lengths and other indicators of fibre polydispersity. Depending on the needle field width, fibre length of cotton or wool type can be measured. The test method is standardized.
