Dyeing Properties and Ultraviolet-cut Ability of Dyed Fabrics with Petasites japonicus Extract

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.

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.

3% hyperbranched polymer was incorporated into polypropylene and dyed with Disperse Blue 2BLN. The observed enhancement of dye uptake can be attributed to the introduction of polar groups. The finding that dye uptake on the modified fiber reached a maximum at 110°C suggests that “saturation” had occurred. While the washing fastness of dyed fabrics made from polypropylene fiber which had been modified with hyperbranched polymer was very good, the fastness of the dyeings to light was poor. The incorporation of 3% hyperbranched polymer into polypropylene prior to fiber spinning had no effect on the physical properties of the fiber，however markedly enhanced the dyeability of polypropylene.

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.

Collagen Immobilization

Collagen was immobilized onto moderate acid activated polyamide fibers with glutaraldehyde (cross-linking agent) aimed to improve its sanitary property. The immobilization of collagen onto polyamide fiber was estimated by dyeing collagen modified fabrics with a cationic brilliant red 5GN, and determining the dyeing properties of the dyed fabrics. The modification also confirmed technically by Differential scanning calorimetry (DSC), Scanning electron microscopy (SEM) and Atomic force microscope (AFM). Cationic dyeing showed brighter and more even dyeing properties of the collagen modified fabrics compared to the non-treated fabrics. From DSC results, it was found that the thermo-stability of the non-treated and collagen modified fabrics changed a lot. The morphology of different samples from SEM and AFM also approved the immobilization of collagen. The moisture absorption and hydrophilicity of the fabrics after collagen immobilization improved compared to the non-treated fabrics.
