Our partner Covec™ Ltd is a company focused on ‘Technical Textiles’ These are textiles made from yarns with engineered solutions, they can be synthetic fibres mixed with natural fibres or engineered synthetic fibres produced to meet performance criteria.
Covec™ SR4, SR6 and +7 are unique laminated constructions consisting of around 300 up to 750 gsm knitted textiles made of high performance yarn, this offers, beside strength, density and a softer knitted feel. The unique construction improves the drape when wearing. The increased density of Covec™ +7 offers unrivalled high speed abrasion resistance, tested to outperform the highest reported figures seen in motorcycle jeans with Covec™ +7 scoring 7.97 seconds using the most aggressive abrasion test currently available, CE EN 13595-1.
Covec™ SR4, SR6 and +7 offer certain advantages over more traditional materials like Aramids and UHMWPE’s and a lot of advantages over Polyamide yarns (like Nylon) and Polyesters yarns. Depending on the material you compare it with, Covec™ yarn has higher abrasion resistance, higher cut resistance, lower friction heat transfer and is more resistance to wear for prolonged performance. Below the video a detailed explanation.
You don’t want to have to throw your gear away after one season. The first of those properties are rigorously tested in the CE EN 13595-1 standard, the standard used to approve clothing that offer a specified level of performance.
Materials need to provide low thermal conductivity and a high melting point, preventing additional consequential burns in a crash scenario.
Grit and glass on the road can be very sharp.
The longer a material protects when sliding over an abrasive surface, the better.
+7 is CE tested to EN 13595-1 Level 2 for 7.97 seconds, making them the FIRST jeans in the world to perform to level 2 safety. SR6 is tested to 6.26 seconds, SR4 to over 4 seconds. The polymer in our yarn was tested by NASA as a replacement for Aramids in 2004; it was used for the MARS ROVER space missions providing impact and abrasion protection for the space craft.
The increased density offers unrivalled high speed abrasion resistance, tested to outperform the highest reported figures in motorcycle jeans using the most aggressive abrasion test currently available, EN 13595-1 clause 5.4. If you score the different fibres used in motorcycle clothing against toughness, specific tenacity, elongation at break and specific modulus, you get the following results.
Covec™ provides low thermal conductivity and a high melting point, preventing additional consequential burns in a crash scenario. Some jeans use high thermal materials such as UHMWPE’s, Nylon, Polyester and Hi Abrasion Resistant Textiles with low melting points or high thermal conductivity, either way it can burn you or melt to your skin. Clearly materials with high heat conductivity and low melting point are unsuitable in situations where heat is produced due to friction against abrasive road surfaces. Any product may incorporate high performance fibres and yarns but its performance will be defined in certain circumstances by the lowest common denominator in any given situation.
When a material retains moisture it will become weaker over time, with chemicals often functioning as catalyst. Aramids for instance can retain up to 7% of moisture, while Covec™ can only retain 0.01% of moisture. Sweat is an acid between 3.3 and 5 pH, detergents are alkali between 9 and 11 pH, people use bleach for washing, grease and oils are on bikes, etc.
There are many chemicals that can come into contact with riders gear in daily life. Many of these chemicals can have a degenerating effect on polymers and some have a devastating effect. For instance, bleach destroys Aramids rapidly (1 to 2 washes), while Aramids have an overall good resistance to halogens, they are more severely attacked by acids. The graph here below shows the relative scores on chemical resistance per material and chemical type. 1=poor, 2=fair, 3= good:
This is the loss of strength after repeated bending or folding (in a washing machine, for instance) in the graph below you see the relative scores.
This is the effect of the yarns in a fabric rubbing against each other. The scores in the graph below are the cycles to break on a standard (dry) yarn-to-yarn abrasion test setup, both Polyamide and Polyester outscore the super fibres.
