The biggest continent continues to grow
Asia is the world's biggest continent, comprising 45 countries and extending from the equator to the Arctic Circle. It covers an area of more than 44.5 million square meters – that is, around one third of the worldwide land mass. Alongside many poorer countries it also contains some of the wealthiest lands in the world. The continent's population numbers roughly four billion – equivalent to around 60 percent of all the people in the world.
The world's population is continuing to grow, and on average is becoming ever older. This growth is of course driving urbanization, especially in Asia. Today almost 50 percent of human beings on this planet live in cities. Over the next 40 years, that figure will rise to 70 percent – an enormous challenge, on many levels. Secure food and power supplies, availability of affordable housing, and effective national and international transport connections are just a few examples here.
A special challenge will be to reduce energy requirements, so as to maintain living standards in cities in the future as well. Cities currently account for around 80 percent of the planet's total CO2 emissions.
Fewer emissions, more potential for geotextiles & filter
The growth in Asia presents the nonwovens industry with great opportunities. Worldwide, cities are investing around 2 billion Euro in their infrastructure – so the hope is that there will be steadily increasing demand for geotextiles. The fight to reduce CO2 emissions will also require the increased production of filters. There are further areas of application too: since an increasing number of people live in areas without sufficient drinking water, high growth rates for the drinking-water filter sector are also expected.
With its Technology and Development Center (TEZ) Groz-Beckert offers not only its German customers but all its customers worldwide the opportunity to either initiate such products or to further develop them.

Differing requirements, constantly high quality
The most important countries so far in the nonwovens sector for Groz-Beckert are China, Japan, South Korea and India. The main areas of application range from artificial leather, filter products and paper-machine felts to automotive felts, geotextiles, floor coverings and felts for insulation.
In Japan, growth in the nonwovens industry is beginning to stagnate. The products from Japan are primarily impressive for their outstandingly high quality. Fine and ultrafine gauge needles with rounded barbs are primarily used here (RF and HL), providing a very good and even product surface while achieving optimal gentleness to fibers at the same time.
In addition to barb needles so-called structuring needles are used – i.e. fork and crown needles. They are especially suitable wherever quality requirements are extremely high, e.g. the automotive sector. Groz-Beckert is the only manufacturer on the market able to provide a structuring needle in the fine gauge 43 gg, which despite its filigree design is stable enough for the manufacture of the highest-quality products.
Groz-Beckert also offers needles with special coatings which not only prevent corrosion but also lengthen needle service life. As a full assortment provider Groz-Beckert can of course deliver needle types for less demanding applications as well. This involves needles with so-called conventional barbs, which have also proven themselves to be very suitable for highly specialized and technically demanding applications. Products manufactured in this way include synthetic leather and felts for automotive interiors.
Needle rotation system
In addition to selection of a suitable needle type, handling of the needles as well as the right exchange cycles are of crucial importance where product quality is concerned. Customers interested in overall optimization of their product receive support from Groz-Beckert in the form of useful suggestions as well as specific recommendations with regard to the introduction of a needle rotation system.
Needle with open barb
Solutions for inorganic fibers
For insulation felts made from inorganic fibers such as glass, ceramic or mineral wool place special requirements on needles, because these types of fiber generally display very low elongation and can thus break quite quickly.
Moreover, needles used in the processing of inorganic fibers suffer an extremely high degree of wear. This is why needles that have undergone metallurgical treatment are the product of choice here. This special coating is marketed by Groz-Beckert under the brand-name of GEBEDUR® II. Sometimes, very special needles equipped with an "open barb" are used to successfully redirect numerous fibers into a vertical position. In the case of voluminous insulation nonwovens, combinations of needles can also be employed. These gradually taper towards the end in order to achieve complete needling and to reduce needle breakage.
Jet strips
In the jetstrips sector for hydroentanglement products, Asia is the world's largest market. Continuing growth is primarily due to the hygiene sector, the main centers of which are located in the provinces of Shanghai, Fujian, Haian and the region around the Yangtse Delta.
In this product segment, too, Groz-Beckert has successfully gained a foothold in the Asian market. One reason for this is comprehensive customer support – just as with the needles. Materials are analyzed and optimized so that the performance specifications of the jetstrips can be continuously improved.
Not least of all, Groz-Beckert offers information documentation on all the important aspects of hydroentanglement, from the ideal way to clean jetstrips and special treatment for increasing scratch resistance and service life to technical service and process water analysis.
