Alba certified to EN 20471

In June 2017 XM Textiles polyester fabric Alba has been successfully tested and certified to EN 20471 (High visibility clothing – Test methods and requirements).

ALBA (MULTI-TEX)

Alba it’s an innovative fabric with multi-layer construction. Practical and pleasant to the touch with eye catching design, this fabric has successfully entered workwear market. The material of the membrane consists of several layers which are firmly bonded to each other by lamination. The outer layer comprises a durable, abrasion-resistant fabric. The inner layers are more soft, good insulating and breathable.

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.
EN 20471 certification involved tests for colour performance requirements and color fastness as new and after different test exposures like Rubbing, Perspiration, Laundry and Water vapour resistance, Domestic washing 5 cycles at 60C.
