The innovative way to ensure optimal water and nutrient conditions…
Our Agrotas range of SAF and converted products allow you to achieve optimum nurturing and growth conditions whilst effectively reducing overall water usage.
Our unique fibrous technology creates new possibilities for the development of nonwoven fabrics that can be used as both temporary and long-term solutions, from hanging basket liners to commercial scale projects, even in areas of low water availability. Such fabrics are designed to achieve highly controlled delivery of water and nutrients to root systems, whilst significantly reducing evaporative loss and water seepage. SAF can also be dosed directly to the soil.
Advantages of Agrotas:
These tailored nonwoven fabrics can be cut to shape and used to line the base of potted plants and hanging baskets, and can even be used in vertical gardens. They work by absorbing the necessary quantity of water which then provides an optimum moisture environment for growth. Using this technology can decrease water usage by up to 50% and significantly reduces the need for re-watering. Fertilizer can also be added to the water to aid the control of dosage levels.
Such fabrics are designed to be positioned around the plant on top of the soil. They offer additional benefits in reducing weed growth and improving the overall thermal regulation of the soil environment.
Durable fabrics developed to be buried below ground level. Studies have shown up to 30% annual reductions in water usage for large grassed areas. Such fabrics have been designed for ease of installation – typically 15-20 cm below the surface – and do not biodegrade or lose performance over the long-term. Modifications to the fabrics can be made, e.g. incorporating seeds and other growth factors, so that the ideal growing environment is available within a single format to which just water is added.
Technical Absorbents can supply Super Absorbent Fibre and converted nonwoven fabrics, yarns and tapes into the agriculture/horticulture markets.
Innovative super absorbent water-blocking technology...
Our SAF technology is the key component in a range of geosynthetic membrane fabric technologies and is an ideal way of achieving water-blocking functionality for both short and long-term applications. It can be converted into a wide range of formats for use in a spectrum of industries requiring critical water sealant solutions. Such fabrics benefit from an even absorbency distribution profile and are designed to act as a complete water barrier. The fabrics work by absorbing water until the membrane swells. At a certain point, this then becomes an impermeable barrier to water, completely alleviating the problems of flooding and water seepage.
Advantages of Geotas:
Fabrics from our Geotas range have the ability to separate, filter, reinforce, protect and/or drain, and offer many advantages that are extremely important to demanding civil engineering projects. The fact that they can be supplied in rolls is also a huge benefit when being used on large-scale projects, including:
Technical Absorbents can supply Super Absorbent Fibre and converted nonwoven fabrics, yarns and tapes into the geotextiles markets.
Optimum extreme environment performance...
SAF can be converted into a wide range of disposable and durable fabrics for use within performance apparel. Being fibre-based, our fabrics can be precisely tailored into a diverse range of coolant fabric formats that offer the potential for enhanced design and performance. Such fabrics create the optimum conditions to significantly reduce heat stress and fatigue, increase wearer comfort and maximise physical performance – even in the most extreme environments. Solutions that can be worn both next to skin and over outer clothing are available and are based on cooling through evaporation of absorbed water, or cooling through absorption of body perspiration.
Advantages of Komfortas:
K-SorbTM – Stay dry, stay cool
K-Sorb is a woven, washable, durable material contains the company’s patented Super Absorbent Fibre (SAFTM) and provides unparalleled levels of absorption and retention of sweat, which in turn affords the wearer a cool, dry feeling. The fabric is designed to provide effective results when wearers are working in extreme or challenging environments, or wearing heavy outer clothing.
It can be converted into a wide range of washable garments which are worn next to the skin in such situations.
The composite structure of the K-SorbTM material allows sweat to rapidly be absorbed from the body, providing a dry, comfortable feeling for the user. The sweat is locked away within the highly absorbent core, reducing wet back and the wet, clammy feeling. In addition, a water proof outer layer reduces the risk of wet back onto outer garments, keeping the rest of the user’s clothes dry and fresh. The fabric is designed to absorb up to 10 times its own weight of sweat during use, the equivalent of 4.5l of sweat for a standard size jacket (1.5 square meters of fabric). In addition, the fabric is fully washable, allowing repeated use. Systems based on this core fabric are the perfect solution for the armed forces and emergency services and can also be employed in sports and other general apparel items in situations where normal evaporation is limited or prevented.
K-Evap – Cooling through Evaporation
This functionality can be achieved by incorporating a SAFTM containing absorbent nonwoven within two outer fabrics, thus creating a three-layer absorption cooling fabric. This can then be tailored as required into a final garment which should be worn over outer clothing. In order to activate, the wearer simply pre-soaks the garment with water and wears as normal. As a result of evaporation, the cooling effect occurs. Items made using this technology can be reused through multiple wetting and drying cycles.
Consistently outstanding water and particulate removal...
A significant reason for the majority of oil and fuel system failures is the presence of
high water levels as dissolved, dispersed and free water. SAFTM is the key component
in a wide range of enhanced nonwoven filter media fabrics that are designed to
remove such contaminants from aviation fuel, automotive diesel and a wide range
of oils, to very low ppm levels, at industry-leading rates. As a result, the technology
helps reduce fuel and oil degradation, provides the required filter quality for efficient
machine operation, offers full compliance to meet stringent international filtration
standards (particularly in the aviation fuel and hydraulic oil markets) and delivers cost
savings over traditional cellulosic-based absorption media.
Advantages of Filtratas:
Aviation fuel – monitor cartridges
Monitor cartridges are based on either outside-to-inside, or inside-to outside fuel flow, and offer excellent filtration rate capabilities. Monitor cartridges based on SAFTM technology incorporate a multi-layer nonwoven composite with a revolutionary SAFTM-containing nonwoven structure. This has an MSEP rating of >90 (ASTM D3948) and is compliant to IP 1583 (6th Edition) specification.
The cartridges have been designed to reduce particulates to < 0.3mg/litre of solids in effluent and reduce free and dispersed water to <5 ppm in effluent. The system flow is halted when the media is hit with a localised slug of water and a gel block is formed. Presence of water/solids in the incoming fuel gives rise to an increase in pressure differential, or a decrease in the flow rate, as the cartridges reach their maximum capacity for solids, water or a combination of both.
Automotive diesel – filter cartridges and spin on oil filter media
These filter cartridge systems are composed of a pleated particulate layer and a multi-layer SAFTM -based fabric, and have been designed to remove free and emulsified water to less than 2 ppm. They have high water absorbing capacity capabilities and effectively filter silt and other particulates with no media migration or linting. In addition, the SAFTM component offers an antimicrobial function and does not affect oil additives. A differential pressure increase indicates when the cartridges need replacing.
Hydraulic oil – high bulk SAF-based nonwoven filter media
These filter media are designed to provide excellent particulate and water removal performance. As a result, they reduce oil mutagenicity and the risk of contaminant damage to parts, and machinery – thus extending the working life of the oil. They are combined with other synthetic filter elements within the main housing unit and can be used in both static and portable systems. They are suitable for use with a wide range of oil types, including waste oils, e.g. cooking oil, they can remove dispersed and free water to <150ppm in minutes. Such filter systems can be by-pass or full flow based.

Optimum protection from water ingress...
Technical Absorbents provides extremely high levels of innovation and product development expertise to the global cable market with its Super Absorbent Fibre (SAFTM) technology and SAF-containing yarns and nonwoven tapes from its Cabletas range.
SAF-containing yarns and tapes provide optimum water-blocking/swellable protection for internal and external cable applications. This dry active system prevents water passage along the cable from a joint or point of sheath damage. The highly effective protection is achieved by a SAF-containing water-swellable yarn or tape being incorporated into the cable during manufacture.
How it works
Cables that suffer damage can start to take on water. If a SAF-containing tape or yarn is in place, this will rapidly absorb the liquid at the point of entry and swell to form a gel, blocking any further water ingress. Any damage is minimal, fully contained and easy to locate and repair. Application is ideal for many different cable types including telecoms, medium and high voltage, industrial and underwater. Without water-blocking technology, the results of water ingress can be costly and very problematic.
Water blocking is generally required only in medium and high voltage cables that use cross linked polyethylene (XLPE) insulation. In copper cabling, water can ingress into the cable by diffusion through the outer polyethylene sheath. These cables are typically laid underground in areas likely to be damp and wet so the risk is high. The presence of water will degrade signal strength due to capacitance changes.
Water-blocking protection of an optical cable core is achieved by surrounding it with a dry water-swellable tape and yarn, that will stop entry and migration of water should the cables outer jacket be breached. This protective measure maintains the mechanical integrity of the cable itself preventing ice crush from within the cable, fungus growth, or corrosion of metallic cable members when present. The water-blocking protection is placed in the buffer tubes with the optical fibre during manufacture of the cable.
Technical Absorbents can supply Super Absorbent Fibre and converted nonwoven fabrics, yarns and tapes into the cable markets.
Optimising moist wound care treatment and recovery...
Our SAF technology has been extensively developed for use in advanced moist wound care dressings. Once converted, the resulting versatile, consistently high performing fabrics provide a therapeutic effect and aid healing, especially when used in the treatment of chronic burns and wounds with high exudates. Rapid uptake and retention of exudates from an infected area facilitates the perfect environment for effective management and swift healing, by controlling moisture levels around the wound whilst preventing excess wetting. This is essential in creating an optimum environment to aid the healing process and prevent further bacterial growth. We are already actively engaged in intensive development, and creating solutions for this diverse and challenging market.
Advantages of Meditas:
Selecting SAF as the absorption component affords significant benefits to medical device producers, patients and carers. Its fibrous form creates lightweight, soft and flexible fabrics. These offer precise absorbency control, fluid retention and porosity, with low dust and shedding performance. Enhanced
absorption and retention levels also mean dressings need changing less frequently. Our medical fabrics are available in a wide range of formats and can also provide different levels of anti-microbial and anti-inflammatory performance.
Our technology can be used in other medical-related products such as disposable mats for use in operating theatres. It can also be incorporated into diagnostic transportation solutions, such as packaging for medical testing kits and blood, and bodily-fluid testing materials. This ensures any potentially spilled fluid is locked away within the fabric for safe disposal.
Use in stoma care and transdermal applications are in development.

The ultimate dust and granular material stabilisation and control system...
Technical Absorbents Ltd (TAL) provides high levels of innovation and product development expertise to dust and sand dune control and stabilisation (stabilization) markets with its Permeatec technology. PermeatecDS is a unique polymer technology developed by TAL and is aimed specifically at the control of dust and stabilisation (stabilization) of loose, granular materials. PermeatecDS can be applied to such materials – as an aqueous surface spray – to control dust and sand, sand dunes, and provide a hard, durable surface. In addition, it can be mixed directly with loose, granular material to provide a solid block of material.
How it works
PermeatecDS is a complex acrylate-based polymer system, designed to be dispersed in water, aiding application and improving safety/handling. The polymer is able to coat and bind loose materials, forming a complex web of interlocking particles and polymer, which – when dried – form a hard, durable material. The ability to change application rates, provides the user with precise control and allows stabilisation levels, strength and durability to be tailored as required.
PermeatecDS is available in a number of formats, dependent upon customer need and requirements:
Tools and equipment
PermeatecDS has been designed for ease of use. For the prevention of airborne sand and dust, the polymer can be dispersed in water to form a liquid. This can then be applied directly to the treatable area, using all conventional liquid application equipment. Alternatively, where the mix is to be cast or used as a render, it is better to physically mix the PermeatecDS and water with the sand or other granular material (and optionally PermeatecSR). In such a case, all mainstream manual and automated cement/concrete mixing equipment/techniques can be used.
