Los avances de la nanotecnología han alcanzado de manera importante a la industria textil confiriendo nuevas propiedades con gran beneficio para el usuario. En ese sentido en el presente estudio evaluamos las propiedades físicas-mecánicas de textiles de algodón con tejido tipo calada, funcionalizados con nanocomposito (nanopartículas de plata y Carboxilmetilquitosano). Se realizó los siguientes controles de calidad más relevantes como son la resistencia a la tracción, evaluación del índice de color y evaluación subjetiva de la textura. El ensayo de Resistencia a la Tracción se realizó según la norma estándar ASTM D5034 para urdimbre y trama del textil; utilizado un Dinamómetro de 3kN. Los resultados de resistencia a la tracción para urdimbre sin tratamiento fue un promedio de 72.400 kgf y el funcionalizado registro 70.213 kgf. Por otro lado, la resistencia en trama sin t...

Cotton is the most widely used natural fiber for textiles but its innate capacity to absorb moisture, retain oxygen, and high specific surface area make it more prone to microbial contamination, becoming an appropriate medium for the growth of bacteria and fungi. In recent years, the incorporation of silver nanoparticles in textile products has been widely used due to their broad-spectrum antibacterial activity and low toxicity towards mammalian cells. The aim of the current study is to synthesize and characterize a nanocomposite based on silver nanoparticles and carboxymethyl chitosan (AgNPs-CMC), which was utilized to provide a functional finish to cotton fabric. The scanning electron microscope (SEM) to produce a scanning transmission electron microscope (STEM) image showed that the nanocomposite presents AgNPs with a 5–20 nm size. The X-ray diffraction (XRD) analysis confirmed the ...
