Improving Colorant Absorption from Pistachio Hulls on Wool Fiber Using Protease Enzyme
نویسنده
چکیده مقاله:
Nowadays, textile processing based on biotechnology has gained its importance in the view of stringent environmental and industrial safety conditions. The use of protease enzymes in protein fibers to improve some physical and mechanical properties is particularly interesting. In this research, wool yarns were first treated with different concentrations of protease enzymes in aqueous solution including 1%, 2%, 4% and 6% o.w.f. for 60 minutes. The dyeing process was then applied on the treated yarns with pistachio hulls as a fruit waste. Some of physical, mechanical and colorimetric properties of the treated wool yarns were discussed. Tensile strength of the treated yarns was decreased due to the enzyme treatment and it continued to decrease with an increase in the enzyme concentration in solution. Lightness was decreased for the samples treated with enzymes. The wash and light fastness properties of samples were measured according to ISO 105-CO5 and Daylight ISO 105-BO1. The washing fastness properties of the treated samples were not changed. In the case of light fastness properties, it was increased a little for 4% and 6% enzyme treated samples

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained 111.40 g kg-1 total phenol and 71.30 g kg-1 total tannin per dry matter of e...
متن کاملEffect of rumen bacteria from sheep adapted to a tanninferous diet on in vitro fermentation parameters of pistachio hulls using bovine inoculum
Sheep adapted to consume tannins rich feeds such as oak leaf (OL) appear to develop defensive mechanisms by their ruminal bacteria against these polyphenols. The capabilities of ruminal isolated tannins resistant bacteria from these animals to ferment a tanniniferous feed (i.e., pistachio hulls, (PH) which were incubated with rumen fluid from Holstein dairy cows was assessed. Six g positive coc...

Z-trim is a zero calorie cellulosic fiber biopolymer produced from corn hulls. The micro-structural heterogeneities of Z-trim biopolymer were investigated by monitoring the thermally driven displacements of well-dispersed micro-spheres via video fluorescence microscopy named multiple-particle tracking (MPT). By comparing the distribution of the time-dependent mean-square displacement (MSD) of p...
