ALKALI TREATMENT OF POLYESTER FIBERS

open access: yesSen'i Gakkaishi, 1960
Fibers, made from polyesters of β-hydroxyethoxy aromatic acids, and their copolyester, and those from polyethylen terephthalate (PET), were treated with aqueous caustic soda solutions.Rate constants of solution, k (g/hr/cm2), are calculated from the equationwhere x is the loss of weight by solution, d0 (cm) the initial diameter of a fiber, t (hr) the ...

Alternative chemo-enzymatic treatment for homogeneous and heterogeneous acetylation of wood fibers [PDF]

open access: yes, 2018
A new chemo-enzymatic treatment is proposed to produce cellulosic fibers suitable for heterogeneous- or homogeneous-phase acetylation. The procedure included enzymatic (laccase–violuric acid) lignin removal from the precursor fibers (unbleached sulfite ...
