Abstract We present the ‘SISAL webApp’—a web-based tool to query Speleothem Isotope Synthesis and AnaLysis (SISAL) database. The software provides an easy-to-use front-end interface mine data from SISAL database while providing SQL code alongside as a learning tool. It allows for simple increasingly complex querying of based on various metadata fields. webApp version currently hosts SISALv2 wit...

ABSTRACT The production of sisal in Bahia, Brazil, has been declining due to the occurrence of a disease know as bole rot. Aspergillus niger was regard...

We have studied the structural modifications of lignins from sisal and flax during their soda-anthraquinone (AQ) pulping and subsequent totally chlorine-free (TCF) and elementary chlorine-free (ECF) bleaching. For this purpose, residual lignins were isolated from pulps, analyzed by Py-GC/MS, 2D-NMR, and GPC, and their characteristics were compared to the “milled-wood” lignin of the raw material...

The present work aims at the chemical characterization of several non-woody fibers from herbaceous plants used for manufacturing high quality paper pulps, with especial emphasis in the composition of lignin and lipophilic compounds. Among the fibers studied are bast fibers from flax, hemp, kenaf and jute and leaf fibers from abaca and sisal. Flax and hemp showed the lowest lignin content (< 5%)...

In this study, the different effects of weave structure on comfort properties fabrics and mechanical fiber-reinforced composites were investigated. Fabrics developed using one type material (flax spun yarn) in warp direction three materials (flax, sisal cotton weft directions. Four types weaves (plain, twill, matt mock leno) produced each material. Twelve specimens a sample weaving machine. The...

Properties of sisal fibers such as high coarseness and poor drapability made the less suitable in production conventional textiles compared to synthetic fibers. The environmental consciousness depletion petrochemical resources have attracted researchers on investigating use natural industrial textiles. Sisal is among highly researched due its features strength, recyclability, availability, low ...

Natural-fiber-reinforced composites are seen as a good alternative to traditional synthetic-fiber composites. However, successfully implement these materials in engineering applications, along with demonstrating satisfactory load-bearing capacity, it is necessary provide engineers effective material properties, well calculation methods that take into account the distinctive features of natural ...
