Abstract
Apresenta-se um processo para a produção de uma tela de papel de seda (71) não enrugada, forte, macia e de baixa formação de poeira, utilizável na fabricação de produtos sanitários absorventes macios, como lenços higiênicos, lenços faciais e lenços absorventes. Os papéis de seda compreendem fibras, como polpa de madeira, e uma carga não celulósica, insolúvel em água e em partículas, como argila caulim. O processo para a incorporação de uma carga não celulósica em partículas em um papel de seda compreende as etapas de: (a) formação de uma suspensão aquosa de material para fabricação de papel compreendendo fibras para fabricação de papel e carga nao celulósica em partículas, a carga em partículas compreendendo, de preferência, de cerca de 1% a cerca de 50% do peso total do papel de seda, a carga em partículas sendo selecionada no grupo que consiste em argila, carbonato de cálcio, dióxido de titânio, talco, silicato de alumínio, silicato de cálcio, alumina triidratada, carbono ativado, amido em grânulos, sulfato de cálcio, microesferas de vidro, terra diatomácea e suas misturas, mais preferivelmente, a carga em partículas sendo argila caulim com um diâmetro esférico equivalente médio entre cerca 0,5 <109> e cerca de 5 <109>; (b) deposição da suspensão aquosa de material para fabricação de papel sobre a superfície de um tecido de formação foraminoso em movimento (85), para formar uma tela embrionária molhada para fabricação de papel (98); (c) transferência da tela embrionária molhada para fabricação de papel (98) do tecido de formação (85) para um primeiro tecido de transferência (86), que se desloque a uma velocidade cerca de 5% a cerca de 75% mais lenta que a do tecido de formação (85) e (d) transferência da tela embrionária molhada (98) para fabricação de papel do primeiro tecido de transferência (86), mediante pelo menos uma transferência adicional, para um tecido de secagem (90), com o que a tela embrionária molhada para fabricação de papel (98) é secada não compressivamente.
