Polar Fleece-270 (Hi-Viz Orange) certified to EN 20471

April 2021, XM Textiles polyester fabric Polar Fleece-270 (Hi-Viz orange) has been successfully tested and certified to EN 20471 (High visibility clothing – Test methods and requirements).

Polar Fleece-270  is medium weight material. Fleece is a synthetic material made of polyester, which does not absorb moisture, but instead helps to transport it away from the body. The workwear jackets or sport vests made from the fleece are lightweight, very warm and quite durable especially when reenforced on shoulders and elbows with additional layer of outer fabric like Oxford or Taffeta.

The Standard EN 20471:2013 specifies requirements for high visibility clothing which is capable of visually signaling the user’s presence. 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.

Performance requirements are included for colour and retroreflection as well as for the minimum areas and for the placement of the materials in protective clothing.
According to standard EN 20471 has been successfully passed all the following tests:

The chromatic coordinates must be situated within the area defined by the coordinates specified in the Standard EN ISO 20471:2013/A1:2016 and the luminance factor shall exceed 0,70 specified in the Standard EN ISO 20471:2013/A1:2016.
Alba passed the test with the following results:

• Original: 0,41- PASS
• After exposure to Xenon light: 0,45 – PASS
• After 5 washing cycles  4N + F: 0,42 – PASS

The limit set by the Standard EN ISO 20471:2013/A1:2016 for color fastness to rubbing is 4, in dry.

• Warp (dry staining): 4-5 – PASS

• Weft (dry staining): 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

ALKALINE SOLUTION

• change in colour: 5 – PASS
• staining (cotton/polyester): 4-5 – PASS

ACID SOLUTION

• change in colour: 5 – PASS
• staining (cotton/polyester): 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 washing, is 4-5 for degradation and 4 for staining.

• change in colour: 5 – PASS
• staining (cotton/polyester): 4-5/4-5 – PASS

The relative expanded uncertainty of Bursting resistance according to standard EN ISO 13938-1:2019 is ±8% assay value of the measured, for a probability of coverage of 95%.
The test standard EN ISO 13938-1:2019 hydraulic equipment used and the EN ISO 13938-2: 2019 pneumatic equipment usually reach 800kPa. Both standards specify that there is no significant difference between the two teams to 800kPa.
The minimum bursting resistance has to be ≥ 200 KPa.

• Bursting strength:1160,4KPa – PASS

According to the requirements of EN ISO 20471:2013+EN ISO 20471:2013/A1:2016, if the water vapor resistance is higher than 5 m2Pa/W is to be measured the thermal resistance to determinate the water vapor permeability index. The water vapor permeability index to should be ≥ 0,15.

Water vapour resistance Ret (m2Pa/W): 12.39 – PASS

ISO 5077:2007 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.
Negative dimensional change indicates shrinkage
Positive dimensional change indicates lengthening

• Warp: -2.0N – PASS
• Weft: +1.0N – PASS
