The secret of cut-resistant gloves: engineered yarns

Dpto. Marketing y Comunicación 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.

Juba: Committed to sustainability and the future of the planet

Juba's team is very proud to announce another important step in its commitment to sustainability. Over the past few years, it has worked hard to calculate its carbon footprint and effectively reduce it. Now, it wants to go further and offset its environmental impact by actively contributing to the fight against climate change. To this end, the company has planted more than 6.800 trees in the municipality of Pobladura del Valle, Zamora, creating a natural CO2 sink. This forest not only captures carbon, but also offers numerous ecosystemic benefits that contribute to the improvement of the environment and local communities. Benefits of the project in Pobladura del Valle 🌳 The creation of this carbon sink not only helps to mitigate the effects of climate change, but also brings a number of tangible environmental and social benefits: Increased biodiversity: We increase the variety of plant and animal species, creating a richer and more balanced ecosystem. Production of natural resources: We enhance both timber and non-timber resources, supporting the local economy in a sustainable way. Landscape and visual improvement: We beautify the environment, creating natural spaces that enrich the landscape and provide recreational areas. Soil protection and restoration: Our trees help prevent erosion and improve soil quality. Increasing water catchment capacity: We contribute to improving the land's capacity to absorb and retain water, protecting water resources. Supporting the fight against depopulation: We promote the reactivation of rural areas and the generation of opportunities for their inhabitants. Development of research projects: We promote scientific studies that help us to better understand how to optimise these ecosystems for greater environmental benefit. Juba's contribution to SDG 13: Climate Action 🌍 This project is aligned with Sustainable Development Goal 13: Climate Action, which seeks to take urgent action to combat climate change and its impacts. Through the creation of natural carbon sinks, we not only contribute to reducing the concentration of CO2 in the atmosphere, but also help to create resilient ecosystems that mitigate the effects of climate change, such as droughts, fires and loss of biodiversity. In this way, we are committed to being an active part of the global fight against global warming and to promoting natural solutions that benefit both the environment and local communities. Together for a more sustainable future 🌱🍋 This project is just the beginning. The Juba team firmly believes in the power of small actions to make a significant impact on our planet. On this journey, they have surrounded themselves with the best partners: Ecosil and CarbonX, who share their vision in this adventure towards a more sustainable future. At Juba, we will continue to work tirelessly to minimise our environmental impact and provide solutions that benefit everyone. We are convinced that, by joining forces, we can make a big difference. Thank you for being part of this journey towards a greener and healthier world!
