The secret of cut-resistant gloves: engineered yarns

Comunicación Juba 23 January 2018

Category: News

Engineered yarns are one of the greatest innovations in manufacturing cut-resistant work gloves over the last few decades. Created by combining two or more fibres, the threads produced in this process make work gloves more resistant to cutting, whilst also providing great dexterity and touch.

Engineered yarns are responsible for this great step forward in protecting workers' hands but... what are they exactly?

These threads are the result of manufacturing using two or more fibres, with infinite combinations. The high-resistance components such as Kevlar® or high-performance polyethylene (HPPE) such as Dyneema® are used in the core of the engineered yarn that can become more resistant to cutting by combining this central thread with other fibres. The Dyneema® fibre is polyethylene with an ultra high molecular weight known as UHMWPE, developed and patented in 1990 by Dutch multinational DSM.

It is manufactured in a patented spinning process where the fibres are stretched, heated, lengthened and cooled. The stretching and turning encourage molecular alignment, high crystallisation and low density, all giving it great cutting resistance. Dyneema® has extremely long molecular chains that transfer the load more effectively to the polymer skeleton.

Therefore, it is stronger at the same weight or lighter with the same strength as alternative products.

Up to 15 times stronger than steel (weight for weight). Up to 40% stronger than aramid fibres (weight for weight)

The Juba catalogue includes cut-resistant work gloves manufactured using different engineered yarns.

Here are a few examples of how to combine different threads to obtain cut-resistant gloves intended for a variety of uses.

What kind of work clothes should a welder have?

Welder's work clothes are those specific for welding operations that have to be carried out by professionals in the iron and steel industry. Welding consists of joining metal parts by means of heat or pressure (sometimes both simultaneously). The most common types of welding are the following: Electric welding Oxyacetylene welding In this type of work, the professional is at risk of burns from splashes of incandescent material and from radiation or contact with the work material. This is the main reason for choosing suitable welding work clothing of the highest quality. On the other hand, work gloves are essential to ensure hand protection during welding. As this type of activity requires different finishes and levels of precision, it is essential to select the right glove according to the required touch and intensity of the operation, always ensuring maximum safety without compromising functionality. What are the regulations for welding workwear? The legal provision for the design and manufacture of welding workwear corresponds to Regulation (EU) 2016/425 on personal protective equipment (PPE). In addition, the applicable marking regulations may include the following references, depending on the characteristics of the welding work: UNE-EN ISO 11611:2015 on protective clothing for welders and related procedures. UNE-EN ISO 11612:2015 on protective clothing against heat and flame. UNE-EN ISO 14116:2015 on protective clothing against fire. UNE-EN 61482-1-2:2008 on the protection of workers against electrical hazards arising from electric arcs. UNE-EN 20471:2013 on high-visibility clothing. The UNE-EN ISO 11611:2015 standard, which is the most specific for welding work, also differentiates between two classifications for protective clothing used during welding and related techniques: Class 1: for protection against welding techniques and less dangerous situations, against molten metal splashes and radiant heat. Class 2: for protection in more dangerous situations, where the incidence of molten metal splashes and radiant heat represents a greater risk. What workwear should a welder wear, which is the most suitable? Juba has extra high quality leather gloves and accessories that offer excellent resistance to contact heat, convective heat, flame and small splashes of molten metal. In addition, they are designed for durability and protection in hot environments and at risk of abrasion and tearing. There are two types of welding gloves: Type A welder's gloves: these are those with more general characteristics, recommended for welding with metal inert gas (MIG), where the most important thing is that they offer resistance to heat and where dexterity is not so important. They are thick gloves with strong insulation. Type B welder's gloves: these include references that stand out for their design in which dexterity is improved for more precise work. However, they perform less well against sparks and heat. They are suitable for TIG welding, where tactile sensitivity is essential. It should be noted that TIG welding does not generate as much heat as MIG welding. However, heat build-up is still significant and can be transferred, so while they offer dexterity in use, they must also be thick enough to protect against heat. In these cases, goatskin is a very effective material. Some of Juba's most recommended welding gloves are listed below. Each glove details the characteristics it offers for different types of work: 408 408K 408KS 408OCRE 408KSFM 206AFT 206BFT 208 408TIG 408RTIG As for the rest of the welder's workwear, Juba has a wide variety of models to choose from, depending on the area of the body that needs protection. Split leather sleeves up to the elbow are available in economy versions (451C) or with extra selection leather (251C). Split leather sleeves up to the shoulder are also available in an economical version (451H) or with an extra selection of leather (251H). Welding aprons of various types can also be used for welding work. There are various models ranging from the most economical (452A) to options with extra leather selection (252A, 252B, 252AH, 252BH), all of which are of high quality. For total protection of the welding professional, the 450, 250 and 250C split leather jackets are recommended. As a complement, you can also count on the Westport multi-pocket waistcoat made of 100% polyester quilted cotton and lined with the same material, which Juba offers in its workwear catalogue in two colours: navy blue (860) and grey (860GY). The risks of welding do not exclude the lower torso of professionals. For this reason, we recommend the use of trousers such as model 839BL and split leather gaiters such as references 453A, 253A and 253B.

Classes of clothing offering increased visibility

Juba's catalogue features a wide range of reflective and hi-visibility clothing items designed to offer safety and protection in potentially hazardous work situations in low light conditions, where professionals may not be detected from certain angles, while operating machinery or driving vehicles. Even these garments are recommended to avoid possible accidents for those who enjoy recreational activities in low-light areas, such as cycling, running or walking. High visibility clothing is considered personal protective equipment (PPE) and must combine the latest technology with functional design to ensure that each garment creates an additional barrier to low light hazards. To find out if clothing complies with high visibility standards, check the label on the garment and look for the marking, which will indicate: The name of the manufacturer. The reference or name of the PPE. The size of the garment. The specific pictogram indicating the class of the garment. Details such as an information and explanatory leaflet. The official certification for the sale of personal protective equipment. The number of the standard to which it refers, in this case, EN 20471 according to which high visibility clothing is differentiated into three different classes: What is high visibility clothing and what regulations does it comply with? The great benefit of high visibility clothing is that it guarantees that professionals can be detected at a great distance, to avoid being run over or suffering any type of accident with machinery, vehicles, tools and other elements present in the work space. The standards regulating hi-visibility clothing is EN ISO 20471. This certification ensures that all work wear complies with strict standards of design, materials and performance, essential to protect workers in construction sites, roads, industrial areas and other high-risk areas. Specifically, the regulations determine the amount of reflective and fluorescent material that garments must contain in order to meet high visibility requirements. What is the difference between the two terms? While fluorescent material transforms ultraviolet light into light visible to the human eye thanks to colours like yellow and orange, reflective material makes garments visible in low-light conditions. High visibility clothing classes: 1, 2 and 3 The hi-visibility clothing regulations differentiate between three classes or levels of safety: Class 1 high-visibility clothing Class 1 hi-visibility clothing groups together a set of PPE with lower protection, and should therefore be used when risks are minimal. Depending on the regulations, these garments have 0,10 m2 of retro-reflective tape (reflective stripes), 0.14 m2 of fluorescent background material to meet the requirements of the regulations and 0.20 m2 of combined material (fluorescent and reflective stripes). Class 1 high-visibility clothing is designed to enable professionals to be detected from vehicles travelling at speeds of less than 40 kilometres per hour. Class 2 high visibility clothing The material requirements for class 2 high visibility clothing have an intermediate degree of visibility and therefore must have 0.50 m2 of background material and 0.13 m2 of retro-reflective material to meet the requirements of the standard. This is the workwear professionals need to wear to be easily seen in adverse weather conditions and in workplaces where vehicles or machinery circulate at speeds not exceeding 80 km/hour. Some of the most common references for this type of hi-visibility clothing are waistcoats and trousers. Class 3 high visibility clothing Class 3 high-visibility clothing requires a higher presence of these materials. In particular, the background material should be 0.80 m2 and 0.20 m2 of retro-reflective material. This type of protection is necessary for professionals working in emergency services and in places where road traffic is travelling at speeds above 80 kilometres per hour. Sectors where high visibility clothing should be worn The indications for each class of high-visibility clothing do not preclude that the one that offers the greatest safety can be used in other situations of lower risk. For this reason, it is possible to use Class 3 clothing in working environments where Class 2 or even Class 1 would be sufficient, depending on the level of safety required in each situation. The selection of high-visibility clothing, like any personal protective equipment (PPE), requires a workplace-specific risk assessment. The level of protection required must then be defined according to the risks present and the specific characteristics of the task to be performed. Whether T-shirts, polo shirts, trousers, jackets or high-visibility waistcoats, all these products for professional use must be approved to EN ISO 20471. This is an international standard defining the requirements for garments visually signalling the wearer's presence and establishing the validity and durability of the materials they are made of. It replaces the former EN 471 standard. In addition, they must comply with the requirements of EN ISO 13688 on protective clothing in general. They also usually comply with EN 343 if they are certified to protect against rain. In any case, high-visibility clothing is mandatory for work in these situations: When working near vehicles. On construction sites with heavy machinery. When, in any work, poor visibility means the risk of not being seen. If we base ourselves on the characteristics of each type of high-visibility clothing, these are some of the sectors that use each of them: Professional sectors where to use high visibility clothing class 1 Personnel exposed to light traffic in warehouses. Parking staff. Parking attendants. Track maintenance personnel. Occupational sectors where high visibility clothing class 2 should be worn Airport personnel. Port personnel. Professionals responsible for rubbish collection. Employees of large car parks. Professional sectors where high visibility clothing class 3 should be worn Health professionals. Security forces. Site and construction personnel. Road personnel.
