For instance, in textile processing, a crucial step for successful scouring of fabric is wax and pectin removal [ 6], which is generally performed under high temperature and high alkaline conditions that cause serious environment impacts and raw material loss.
As cotton fibers partially dissolve in concentrated sodium hydroxide at elevated temperatures, fabric strength loss occurred.
As such, during alkaline dye reductive process fabric strength loss occurred.
Fabric strength loss percentages increased gradually with the increase of concentration of stripping chemicals and temperature of stripping bath.
Fabric weight loss percentages of stripped fabrics were increased gradually with the increase of concentration of stripping chemicals and stripping temperature.
But effects on fabric strength loss, color fading, stiffness, shrinkage and GSM are observed with increases of time up to 60 min.
Based on this experimental study, the conclusions drawn were: 1. Fabric strength loss percentages increased gradually with the increase of concentration of stripping chemicals and temperature of stripping bath.
Although indicative, our modelling suggests that reducing fabric heat loss and increasing air tightness may reduce exposure to outdoor pollutants and raise indoor temperatures.
8 10 Energy efficiency retrofits that alter the fabric heat loss can also increase the air tightness of the dwelling, 11 12 increasing exposure to indoor-generated pollutants (eg, particulates, mould, radon).
Changes in molecular parameters (molecular weights and molecular weight distributions), phase structures (crystallinities), morphologies (fiber surface topologies) of the PLLA fibers, and their macroscopic properties (the fabric weight losses and mechanical strengths) were monitored with degradation times.
