To improve the ultraviolet resistance and color fastness of the cotton fabrics, a new multifunctional finishing agent of waterborne polyurethane containing UV absorption group (WPUUV) was synthesized and characterized with 1HNMR and UV spectroscopy. Stability of WPUUV and their finishing performance on cotton fabrics were investigated. Results showed that the various color fastnesses such as the dry and wet rubbing fastnesses, wrinkle recovery angle and softness of the dyeing cotton fabrics were obviously improved by WPUUV, which provided good UV protection function for dyeing cotton fabrics as well.  相似文献

Cotton and cotton/polyester fabrics were treated against microbial attack by applying a formulation based essentially on ZnO under high‐energy radiation and thermal curing. To achieve the homogeneity and the reactivity of the treating formulation, a binder (Impron MTP) and a dispersing agent (Setamol WS) were used with ZnO. The antimicrobial property of the fabrics was evaluated, in terms of mechanical properties, by a soil burial test. Moreover, the effect of antimicrobial finishing on the dyeing properties in terms of color strength was investigated. It was found that the best composition that affords the best antimicrobial protection to cotton fabrics contains 2% ZnO, 2% binder, and 1% dispersing agents. For the cotton/polyester blend, the best results were achieved at the same conditions except the ZnO was 1%. It was found that the treatment under the effect of electron‐beam irradiation is better than that of gamma irradiation and thermal curing. The results showed that when the finishing process was carried out before dyeing with a reactive dye, it affects the color strength rather than performing the finishing after the dyeing process. © 2003 Wiley Periodicals, Inc.

Simultaneous dyeing and durable press finishing of cotton fabrics with reactive dyes and citric acid finishing agent was carried out using a pad-dry-cure process. Factors affecting the process, such as the concentration of dye, citric acid, catalyst and alkali, as well as the curing temperature, were investigated. The dyed and finished fabrics were evaluated with respect to colour strength, crease recovery angle, breaking strength and fastness properties.  相似文献

In this work, after cationic pretreatment of cotton fabric with cetylpyridinium chloride (CPC), the compound of citric acid (CA) and succinic acid (SUA) were used as crosslinking agents to dye cotton fabrics with natural madder dye to improve the dyeing and antibacterial properties and realise the multifunctional finishing of cotton fabric. The effects of mordant dyeing, CA + SUA crosslinked dyeing, and CPC/CA + SUA crosslinked dyeing on the microstructure and properties of cotton fabrics were compared. The dyeing by the three processes occurred primarily in the amorphous zone of the fibres, and all kept the original crystalline form of the cotton. CA + SUA crosslinked dyeing and CPC/CA + SUA crosslinked dyeing increased the thermal stability of the cotton fabric. CPC/CA + SUA crosslinked dyed cotton obtained excellent dyeing results with the colour depth value (K/S) of 12.3 and rubbing fastness and washing fastness of levels 4–5, and the levelness and dye permeability were acceptable. Furthermore, the antibacterial rate against Escherichia coli and Staphylococcus aureus reached 99.99%, and the ultraviolet protection factor (UPF) reached 50+. Moreover, the wrinkle recovery angle (WRA) increased by 55% compared with raw cotton. This showed that CPC/CA + SUA crosslinked dyed cotton had excellent antibacterial, anti-ultraviolet, and anti-wrinkle performances.  相似文献

Carbon black (CB) aqueous dispersion was prepared and used to dye the cationic‐modified cotton fabrics through exhaust dyeing process. The effects of CB concentration, CB nanoparticles size, dyeing bath pH, dyeing time and dyeing temperature were investigated. The color yields of dyed fabrics were evaluated on Kubelka‐Munk value K/S. The surface morphologies of cationic modified and nonmodified cotton fabrics were measured by video microscope. The fabrics presented 18.9 of the color yield with the dyeing conditions: the dyeing solution contained 2% o.w.f. CB and dyeing at 80°C for 30 min with pH 13 using a 50 : 1 liquor ratio. The images of the video microscope demonstrated a clear surface profile for the cationic‐modified cotton fabrics dyed with smaller CB particle size solutions. These results indicated that CB nanoparticles were suitable for dyeing the cotton fabrics. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011  相似文献

The prospects for use of plasma technologies in the textile industry finishing plant in preparation, dyeing, and final finishing of fabrics of different chemical nature are evaluated. It is shown that plasma has the greatest effect on unbleached textile materials due to the important change in their hydrophilicity. Rational schemes of including the stage of plasma activation in finishing of fabrics to increase product quality and economy of manufacture are proposed.Translated from Khimicheskie Volokna, No. 6, pp. 32–37, November–December, 2004.  相似文献
