The Portuguese textile firm Tintex Textiles S.A. and the German textile equipment producer Brückner Textile Applied sciences GmbH & Co. KG are taking a giant step into the longer term along with a newly developed course of know-how for coating bi-elastic knitted materials. The brand new improvement will open new markets and new prospects for either side.
Tintex, a contemporary textile firm positioned in Villa Nova, not removed from the Spanish border in northern Portugal, was based in 1998 within the area of Porto. Tintex’ product vary contains purposeful tricot materials for well-known trend, sports activities and lingerie manufacturers. The corporate is satisfied that trend can actually make a distinction in tackling local weather change. That’s the reason its engineers are always creating new methods and environmentally pleasant ideas all through the entire manufacturing course of. Tintex’ technologists’ experience covers your entire textiles provide chain, together with dyeing and ending methods in addition to coatings.
No sustainability with out innovation
True to the motto, ‘no sustainability with out innovation’, Tintex is consistently researching new cloth improvements to develop and produce clever, purposeful and high-performance textiles and to spherical off the idea, a couple of years in the past it determined to cooperate with the German textile equipment producer Brückner.
The objective is at all times to assume and act with long-term perspective, as a result of that is the one method Brückner and its prospects could be profitable in the long term
Brückner’s product vary contains machines and full strains for coating and ending of textiles, technical textiles, nonwovens and flooring coverings. With its personal manufacturing web site within the south of Germany, fully re-built in 2018, Brückner has turn into much more versatile and aggressive. The family-run firm was based in 1949 and is in the present day managed by second era Regina Brückner and her husband Axel Pieper. Nonetheless legitimate in the present day, the values and visions of the corporate’s founder are the important thing to success: the manufacturing of high-quality strains, the event of sustainable and progressive applied sciences and the competent and complete recommendation of its prospects.
Since each corporations, Tintex and Brückner, share the identical philosophy, the premise for constructive and goal-oriented product improvement was rapidly established. Tintex’ imaginative and prescient was to have the ability to obtain fully new results on bi-elastic knitted materials and to provide materials that didn’t even exist earlier than. This was adopted by quite a few checks within the Know-how Centre at Brückner in Leonberg and on a Brückner line in an institute for textile and course of engineering close to Stuttgart.
In accordance with Brückner, a brand new, revolutionary line idea was labored out collectively, which has unbeatable advantages particularly with regard to the necessities of temperature uniformity, the thermal therapy of artificial fibre blends and different constructive points. Even very tough knitted cloth with excessive elastane content material can now be instantly coated or functionalized. Till now, such coatings had been solely attainable through an oblique coating course of, the corporate says.
The guts of the brand new line is the confirmed, however always additional developed and optimized Energy-Body stenter body dryer. The inlet and outlet elements are specifically designed for delicate cloth and guarantee tensionless cloth run. A particular, newly developed coating unit is built-in within the infeed stand of the stenter body. As a consequence of its variable design, two totally different software processes are attainable on the identical line. Within the so-called display screen coating course of, water-based pastes and steady or unstable foams are utilized onto the material with excessive precision by the use of a pushed, cylindrical display screen and a squeegee system built-in within the display screen.
For paste coating, the machine parameters could be adjusted in such a method {that a} single-side coating is feasible even on mild knit items produced from cotton or viscose, offered the paste is of an appropriate viscosity. For the steady foam coating, the coating medium is combined to foam with an actual foam/litre weight of 150 to 300 g/l. With an built-in feed pump, this foam could be exactly dosed and utilized to the textile by the display screen. Additionally, within the case of unstable foam coating, the coating medium is foamed up with a mixer and utilized to the textile in precise doses. Right here the froth/litre weight is 30 to 100 g/l.
Because the unstable foam collapses shortly after leaving the display screen, a single-side functionalization with a really low pick-up of lower than 10-20 % could be achieved. It is a minimal software with the corresponding advantages, e.g. appreciable power and thus price financial savings within the subsequent drying course of. If you wish to coat considerably extra steady cloth or apply increased coating weights, the unit could be rapidly and simply transformed from display screen coating to a knife-over-cylinder system. The counter stress curler is then used as coating cylinder.
A laminating/embossing calender built-in within the outfeed of the stenter permits numerous results to be achieved on the material, e.g. a leather-based grain. If the utilized steady foam coating has a sure layer thickness, this impact could be achieved after the drying passage within the laminating calender by the use of a fed launch paper or an acceptable embossing curler. Even with delicate, instantly coated knitted cloth, the calender can be utilized to use, for instance a movie, a membrane or a second textile internet onto the material. For this goal, the calender is moreover geared up with an electrical short-wave infrared dryer.
For easy heat-setting processes a particular curler has been developed which could be inserted into the coating unit as a substitute of the display screen and thus acts because the higher infeed curler. Even very tension-sensitive knitted cloth could be run with an overfeed of as much as 60 % earlier than heat-setting.
The brand new multifunctional line can subsequently be used for heat-setting, drying and coating processes. It may be used to fabricate merchandise similar to these beforehand produced with oblique coating – however with out having to depend on cost-intensive launch paper.
At Tintex in Portugal, manufacturing on this line has already been working for a while and analysis into fully new sorts of textiles is continuous. Tintex received the Hightex Award with such newly developed merchandise at Munich Cloth Begin, in addition to the Innovation Award at Techtextil in Frankfurt.
Brückner says it is vitally proud to have prospects like Tintex who act with foresight and don’t try for short-term revenue optimization. The objective, the corporate says, is at all times to assume and act with long-term perspective, as a result of that is the one method Brückner and its prospects could be profitable in the long term.
