An aqueous solution containing a natural colorant (myrrh extract) was obtained by extraction from myrrh using water as an extracting solvent at 90℃ for 90 min with a fixed material to liquor ratio of 1:10. The dyeing properties, color fastness and deodorizing/antibacterial performance of fabrics (cotton, silk and wool fabrics) dyed with myrrh extract were evaluated. The main component in myrrh extract was found to be polysaccharides composed of D-galactose/D-glucuronic acid/L-arabinose and protein. The yellow-red color of fabrics dyed with myrrh extract was attributed to the copper (I) oxide component. The K/ S value of the dyed fabrics increased in the order of cotton < silk < wool. The washing, water and acid/alkaline perspiration fastness of dyed cotton/silk/wool fabrics were good (Grade 4–5), except light fastness (Grade 1–3). The deodorizing performance of dyed fabrics against ammonia and acetic acid was found to be significantly better than the control (undyed) fabrics. The dyed fabrics exhibited an excellent antibacterial performance (99.9% bacteriostatic reduction rate) against both Klebsiella pneumonia and Staphylococcus aureus. These results highlight the strong potential of the natural dyed fabrics as a functional material with both high antibacterial activity and deodorizing function.

Pine Cone Extract

To examine the deodorizing function and antibacterial activity of fabrics dyed with the extract of immature pine cone, a natural dyeing aqueous solution (the extract of immature pine cone, a natural colorant) was prepared. The colorimetric assay and deodorizing/antibacterial performance of fabrics (cotton, silk and wool fabrics) dyed with immature pine cone extract without/with mordant (aluminum sulfate) were evaluated. The components in the aqueous extract of immature pine cone were found to be hemicellulose, lignin, cellulose and tannin. The yellow color of fabrics dyed with immature pine cone extract might be attributed to the lignin component. The K/ S values of dyed fabrics with mordant showed higher values than those without mordant. The color fastness (washing, water and acid/alkaline perspiration fastness) of fabrics dyed without/with mordant was found to be very good (grade 4–5). All of the fabrics dyed without/with mordant also showed good deodorizing function and excellent antibacterial performance. These results demonstrate the strong potential of even natural fabrics dyed with immature pine cone extract without mordant as a functional material with both high antibacterial activity and deodorizing function.

: The dyes are synthesized by 3-Amino-2-thioxo-4thiazolidinone (N-Amino rhodanine) with glutaraldehyde or Terephthalaldehyde by 2:1 mole to form a and b then coupled with diazonium salts p-Amino benzenesulfonic acid and 4-Amino 3,4 disulfoazobenzeneazobenzene by 2:1 to form new different bis monoazo a1, b1 and diazo a2 and b2 acid dyes. Therefore, the synthesized dyes were applied to both silk and wool fabric materials. We also evaluated the antimicrobial activity for these dyed fabrics against two model gram-negative and gram-positive bacteria. Further, the chemical composition of these dyes is emphasized by elemental analysis Aims: This paper aims to synthesize, apply dye and antimicrobial to four new acid dyes based on derivatives of N-Amino rodanine as a chromophoric group. These dyes are used in dyeing silk and wool with the good lightfastness and are also excellent for washing, rubbing, and sweating fastness. Also, we measure antimicrobial activity for silk and wool fabrics toward Gram-negative, Gram-positive. Background: The search for a synthesis of new acid dyes has antimicrobial for gram-negative and gram-positive. These dyes are mainly used on silk and wool fabrics which have excellent for light fastness, washing, rubbing, and sweating fastness. Objective: The present studies were aimed at synthesis, characterization and antimicrobial toward gram- negative and gram-positive. Methods: The infra-red spectrum was recorded using an Infra-red spectrometer, Perkin Elmer/1650 FT-IR. The 1H-NMR spectra were recorded using a Varian 400MHz spectrometer. The absorbance of the dyes was measured in the ultraviolet-visible region between 300 and 700 nm by a UNICAM UV spectrophotometer. The dye uptake by wool and silk fabrics was measured using a Shimadzu UV-2401PC (UV/V is spectrophotometer at λmax) before and after dyeing. The produced dyes were found to have good antimicrobial activity against a variety of bacteria. Results and Discussion: The compounds a1, b1, a2 &b2 shows good antimicrobial activity toward gram-negative (E. coli), gram-positive (S. aurous). The data showed that exhaustion and the fastness properties of silk and wool dyed fabrics were both very high. Conclusion: This work prepares newly synthesized acid dyes based on 3-Amino-2-thioxo-4thiazolidinone derivatives and uses them for dyeing wool and silk fabrics. Both synthetic dyes have good light fastness and fastness properties. Also, all dyes have a good antimicrobial effect.

A series of azo disperse dyes was synthesized using 4-nitro aniline and 2-chloro-4-nitro aniline as diazo components. The coupling components were N,N-diethyl aniline, N,N-bis-β-hydroxyethyl aniline, N,N-bis-β-acetoxyethyl aniline, N,N-diethyl-m-toluidine, N,N-bis-β-hydroxyethyl-m-toluidine and N,N-bis-β-acetoxyethyl-m-toluidine. The structures of the synthesized dyes were confirmed by TLC, 1H NMR and elemental analysis. The spectroscopic properties of the dyes when dissolved in the organic solvents viz. ethyl acetate and methyl benzoate, were investigated. The absorption spectra of the dyes showed a bathochromic shift when the polarity of the solvents increased. In addition, the substituent groups on the dye structures influenced the spectroscopic properties of the dyes. The dyeing properties of the dyes on poly(ethylene terephthalate) and poly(lactic acid) fabrics were also studied. The dyes exhibited a slight difference in shade on the two polyester fabrics. Heat and light fastness properties of the dyed fabrics were also examined.

Natural dyes comprise of colorants that are obtained from animals or vegetable matters without any chemical processing. Natural dyes can substitute synthetic dye and promotes green technology initiatives in the field of textile dyeing. This study was carried out by extracting dyes from pineapple leaves (Ananas Comosus) using three stage mordanting methods using different mordants namely pre-mordanting, post-mordanting and simultaneous dyeing-mordanting. The mordants used were aluminium potassium sulphate, white vinegar and sodium chloride (NaCl). Wool fabrics were used for dyeing. The strength of colour and K/S values of the dyed fabrics were measured before and after washing. The colourfastness to washing, rubbing and light fastness of the fabrics were conducted to investigate the performance of the dye and mordants. The results indicate that the washing, rubbing and light fastness properties of dyed samples were between good to excellent grades.

This paper reports on the application of natural dyes on polyester fabric. Melastoma malabathricum l. was extracted using conventional method of boiling for an hour. Plain lightweight polyester fabric was treated with sodium hydroxide as an alkaline treatment and Chitosan prior to dyeing in an attempt to increase the dye uptake. The dye extract of Melastoma malabathricum l. was applied on the polyester fabric at 85°C for an hour by exhaustion dyeing and 40 minutes for ultrasound dyeing. The colors of the dyed fabrics were measured using colour spectrophotometer and evaluated for washfastness. Ultrasound dyeing gave deeper colour shades to the fabric even though dyeing was conducted at lower temperature for 40 minutes. The alkaline treated fabrics dyed using ultrasound gave lower value of L* which indicate higher dye uptake and darker colour. The ratings for colourfastness to washing were between 4/5 to 5.

Initial Uptake

The dyeing properties of lac dyes for wool, silk and nylon fibers were investigated, and compared in terms of dependence of dye uptake on pH, dyeing rates, and building-up performance as well as color hue and color fastness of dyed fabrics. For all the three fibers, the uptake of lac dyes was greatly influenced by pH, indicating that the electrostatic interaction between lac dyes and fibers predominantly contributes to lac adsorption. The maximum adsorption wavelength of dyed fabrics shifted to a higher value with increasing application pH, indicating the existence of bathochromic effect. Lac dyes showed the quickest initial uptake rate for silk, the slowest rate for wool. The capacity of lac uptake by three fibers was in the following order: wool > silk > nylon, this being in accord with the quantity of amino groups in these fibers. Dyed wool exhibited the best color fastness.
