Abstract
resumo método para produção de tecido não tecido e um tecido não tecido a presente invenção se refere a um método para a produção de um tecido não tecido no qual uma manta que compreende fibras termoplásticas é transferida para um suporte aquecido que tem uma forma côncavo-convexa, e ar quente é so-prado em direção ao suporte pela parte de cima da manta para que a manta seja modelada numa forma côncavo-convexa, que compreende: uma etapa de aquecer o suporte numa faixa de temperatura que abrange desde uma temperatura igual ou acima do ponto de transição vítrea das fibras que constituem a manta, até uma temperatura igual ou abaixo do ponto de fusão das mesmas; uma etapa de soprar um primeiro ar quente para fundir temporariamente en-tre si as fibras da manta para levar a um estado em que a forma côncavo-convexa é mantida; e uma etapa de soprar um segundo ar quente que tem uma temperatura aci-ma da temperatura do primeiro ar quente para fundir as fibras da manta entre si no estado em que a forma côncavo-convexa é mantida e para fixar a forma côncavo-convexa.
