This invention relates to methods for manufacturing super-micro fibers to
produce fibers having dimensions of between 0.003-0.0003 denier per
filament. The manufacturing methods include the following steps: blending
polyamide-polyester mixtures; passing said polyamide-polyester mixtures
through single-path and twin-screw extrusion processes; spinning said
polyamide-polyester mixtures; melting and dissolving said
polyamide-polyester mixtures; and separating polyester compounds from said
polyester-polyamide mixtures to form polyamide compound or super-micro
fibers.
Esta invenção relaciona-se aos métodos para manufaturar super-micro fibras às fibras do produto que têm dimensões de no meio 0.003-0.0003 denier por o filamento. Os métodos de manufacturing incluem as seguintes etapas: misturas misturando-se do polyamide-poliéster; passando misturas ditas do polyamide-poliéster com os processos da extrusão do único-trajeto e do gêmeo-parafuso; misturas ditas girando do polyamide-poliéster; misturas ditas de derretimento e dissolvendo-se do polyamide-poliéster; e separando compostos do poliéster das misturas ditas do poliéster-polyester-polyamide para dar forma a fibras compostas ou super-micro do polyamide.
