December 2018, XM FireLine™ fr-fabric Colombo in red colour has been certified to EN 20471 (Contrast colours).
Colombo is a protective fabric made of 100% long-staple cotton with flame retardant finishing. The fabric includes antistatic yarn. Original twill 2/2 weave.
Examples of use of flame retardant FR fabric Colombo include but not limited to flame resistant clothing for welders, electricians and other professionals who should have heat, flame and antistatic protection. FR jackets, FR pants, flame retardant coveralls and other FR or FR clothing made from fire resistant fabric Colombo will give your employees maximum chance to be safe and protected when working at risk of fire, Electric Arc or impact of Heat and Flame.
The Standard EN 20471:2013 specifies requirements for high visibility clothing. The high visibility clothing is intended to provide conspicuity of the wearer in any light condition when viewed by operators of vehicles or other mechanized equipment during daylight conditions and under illumination of headlights in the dark.
According to EN 20471, our fr fabric Colombo has successfully passed the following tests:
COLOUR FASTNESS TO RUBBING (ISO 105-X12:2016) – performance level – PASS
The method is applicable to textiles made from all kinds of fibres in the form of yarn or fabric, including textile floor coverings, whether dyed or printed. Two tests may be made, one with a dry rubbing cloth and one with a wet rubbing cloth.
Immediate Appraisal after Testing
DRY STAINING
- Wrap: 4-5 – PASS
- Weft: 4-5 – PASS
The limit set by the Standard EN ISO 20471:2013 + A1:2016 for color fastness to rubbing is 4, in dry.
COLOUR FASTNESS TO PERSPIRATION (EN ISO 105-E04:2013) – performance level – PASS
This test is intended to determine the resistance of color of dyed textile to the action of acidic and alkaline perspiration. This criterion does not apply to white products, to products that are neither dyed nor printed, to furniture fabrics, curtains or similar textiles intended for interior decoration.
ALKALINE SOLUTION
- change in colour: 5 – PASS
- staining (cotton/wool): 4 / 4-5 – PASS
ACID SOLUTION
- change in colour: 5 – PASS
- staining (cotton/wool): 4 / 4-5 – PASS
The limit set by the Standard EN ISO 20471:2013/A1:2016 point (5.3.2) for testing of colour fastness to perspiration, is 4 for degradation and 4 for staining
COLOUR FASTNESS TO DOMESTIC AND COMMERCIAL LAUNDERING (EN ISO 105-C06:2010) – performance level – PASS
specifies a procedure to determine the maximum force and elongation at maximum force of textile fabrics using a strip method.
The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical, or chemical treatment. It can be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics, and fabrics made from carbon fibres or polyolefin tape yarns.
The method specifies the determination of the maximum force and elongation at maximum force of test specimens in equilibrium with the standard atmosphere for testing, and of test specimens in the wet state.
- change in colour: 5 – PASS
- staining (cotton/viscose): 4-5 / 4-5 – PASS
The limit set by the Standard EN ISO 20471:2013/A1:2016 point (5.3.3), for testing of colour fastness to dry cleaning, is 4 for staining.
DETERMINATION OF DIMENSIONAL CHANGE IN DOMESTIC WASHING AND DRYING (EN ISO 5077:2008) – performance level – PASS
This test specifies a method for the determination of the dimensional change of fabrics, garments or other textile articles when subjected to an appropriate combination of specified washing and drying procedures.
- Wrap: -2,5 – PASS
- Weft: -1,0 – PASS
In accordance with the Standard EN ISO 20471:2013+A1:2016, the dimensional change shall not exceed ± 3%, both in width warp and in length weft.
DETERMINATION OF BREAKING STRENGTH AND ELONGATION (EN ISO 13934-1:2013) – performance level – PASS
The method is mainly applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical, or chemical treatment. It can be applicable to fabrics produced by other techniques. It is not normally applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics, and fabrics made from carbon fibres or polyolefin tape yarns.
The method specifies the determination of the maximum force and elongation at maximum force of test specimens in equilibrium with the standard atmosphere for testing, and of test specimens in the wet state.
The method is restricted to the use of constant rate of extension (CRE) testing machines.
BREAKING STRENGTH
- Wrap: -1800N – PASS
- Weft: -1200N – PASS
ELONGATION
- Wrap: -12.0% – PASS
- Weft: -14.5% – PASS
The relative expanded uncertainty of Tensile strength resistance is ±5% assay value of the measured, for a probability of coverage of 95%.
WATER VAPOUR RESISTANCE (EN ISO 11092:2014) – performance level – PASS
The application of this measurement technique is restricted to a maximum thermal resistance and water-vapour resistance which depend on the dimensions and construction of the apparatus used (e.g. 2 m2·K/W and 700 m2·Pa/W respectively, for the minimum specifications of the equipment referred to in ISO 11092:2014).
- Water vapour resistance Ret (m2Pa/W): 4,89 – PASS
According requirement of EN ISO 20471:2013+EN ISO 20471:2013/A1:2016 standard, water vapour resistance shall not be higher than 5 m2·Pa/W.
