Cellulose fiber is a tremendous natural resource that has broad application in various productions including the textile industry. The dyes, which are commonly used for cellulose printing, are "reactive dyes" because of their high wet fastness and brilliant colors. The interaction of various dyes with the cellulose fiber depends upon the physiochemical properties that are governed by specific f...

Anthocyanins are natural dye substances that provide attractive colors from red to blue. However, large quantities of Anthocyanins have been found in wastewater from soaked black beans, resulting in environmental pollution. The utilization of theses wastewaters would therefore be an effective way of reducing environmental pollution, and the water could be used to dye silk fabric, displaying...

Sustainable and green materials have been studied in dye pigment productions to reduce their environment impacts from being produced applied. Although natural dyes are an excellent choice move agrowaste, some improvements must be made before they applied given poor fastness. One way of improving properties is adsorption into nanoclay structures give hybrid pigments. This work used tubular hallo...

This study evaluated the color fastness and crust quality of eco-printed leather using various types mordant in natural dye mangrove extract. used 20 sheepskin crusts bark experimental employed a Completely Randomized Design (CRD) with different as treatments. The were Aluminum Sulfate (Al2(SO4)3), Calcium Carbonate (CaCO3), Citric Acid (C6H8O7), Ferrous (FeSO4). results showed that use (FeSO4)...

Silk is valued as one of the prominent protein textile fibers under animal category famous for distinct properties such lustrous appearance, comfort performance, remarkable shiny sheen and also towards bio-applications. In general, silk highly sensitive delicate; hence, there a need protection in order to protect from unwanted impacts chemicals, light insects. According this consideration, work...

A series of novel monoazo-disperse dyes containing pyrazolo[1,5-a]pyrimidine structures were synthesized starting with the coupling reaction between ethyl cyanoacetate and 4-hydroxybenzenediazonium chloride, followed by treatment of the resulting hydrazone product with hydrazine hydrate. The pyrazolohydrazone 6 is then treated with either 2,4-pentandione and enaminonitrile or aryl-substituted e...

Silk is utilized as most valuable fibers based on the unique properties like shiny sheen, remarkable comfort performance and bio considerations. materials possess high applications a natural substrate in textile/garment industry component medical applications. As silk fine, delicate sensitive it needs more care to protect from ill effects of insects, light chemicals. Hence, this work an attempt...

The objectives of the present study were to develop an environmentally friendly, low-price, easy, and fast method for developing antipathogenic (antibacterial, antifungal, antiviral) cuprous-oxide-coated multifunctional fabrics. fabrics first sensitized with citric acid, then Cu2O particles formed using Fehling solution method. cuprous oxide applied cotton To create particles, three different k...

Based on the accretion induced magnetic field decay model, in which frozen field and incompressible fluid are assumed, we obtain the following results. (1) The analytic relation between the magnetic field and spin period is obtained if the fastness parameter of accretion disk is neglected. Our model evolutionary tracks of accreting neutron stars in P-B diagram are different from the equilibrium...
