低温型粘合剂

织物的涂料印花由于具有简单性、适应性和易于配色等特点,已在世界范围内得到广泛应用。据报导,1979年全世界涂料印花占印花织物总量的55％,1980年美国已达80％以上。我国采用该工艺还不够普遍。但随着合纤工业的发展,各类混纺织物数量的增加,其在织物印花中所占比例必将逐年增长。在涂料印花中,颜料是通过粘合剂的作用而在织物上着色,所以,粘合剂直接影响印染质量和印染产品的着色牢度、手感等性能。一般来说,牢度性能除与粘合剂本身的性能有关

Synthesis and properties of the vinyl silicone oil modified polyacrylate core-shell latex as a binder for pigment printing

Vinyl silicone oil (VSO) modified polyacrylate latex is synthesized by emulsion polymerization. The core-shell structure of the latex particle is observed on transmission electron microscopy. The chemical structure of the copolymer was characterized by infrared spectrum. The glass transition temperatures of core-layer and shell-layer of latex particle are determined by differential scanning calorimetry. The size of particle of the core-shell latex is measured on a nanoscale granularity analyzer. The good softening effect of VSO is proved by the application of the latex as a binder of pigment printing on textiles. The good fastness of the printed fabrics is obtained^, which shows that the synthesized core-shell latex can be used as a binder in pigment printing of textiles.

Pigment color printing on cotton and polyester fabrics with electron beam irradiation curable formulations

Accelerated electrons delivered by electron beam accelerator were used to fix pigment colors, incorporated in curable formulation containing diluting monomer and an oligomer, to cotton and polyester fabrics. Tetrahydrofurfurfryl acrylate monomer and trifunctional urethane‐methacrylate (TFUMA) oligomer were used as curable base besides ethylene glycol. The fabrics were printed with these formulations and exposed to various doses of electron beam irradiation generated from the 1.5 MeV (25 kW) electron beam accelerator machine. The irradiation dose, formulation composition, and pigment color concentration were studied. The roughness and color fastness to rubbing, washing, and perspiration of the printed fabrics by electron beam irradiation, were compared to the same fabrics printed by conventional pigment printing pastes. The results showed that cotton and polyester fabrics printed with the pigment colors by electron beam irradiation displayed higher color strength than those fabrics printed by the conventional thermal curing at equal pigment color ratios depending on the kind of pigment color. The durability properties, in term of roughness, rubbing, washing, and perspiration of fabrics printed by electron beam irradiation are better than those printed by conventional thermal curing. © 2008 Wiley Periodicals, Inc.

Properties of ink‐jet printed,ultraviolet‐cured pigment prints in comparison with screen‐printed,thermo‐cured pigment prints

A collection of printed fabrics for men’s shirts was designed and prepared using computer‐aided design/computer‐aided manufacturing technology. The colours for designs were ink‐jet printed on cotton fabrics with pigments and ultraviolet‐cured. These prints represented the target colours for subsequent flat‐screen printing, which was performed using pigment printing pastes and thermal curing. For an exact transfer of colours of the ink‐jet‐printed standard into the screen‐printing process, a computer recipe prediction method was used. A comparison of colorimetric parameters of fabrics printed with both printing techniques shows minimal and acceptable differences in the CIELab colour values. A comparison of colour fastness properties proves that very good colour fastness is achieved on the pigment‐printed fabrics produced with both printing techniques. The flat‐screen‐printed fabrics show better colour fastness to washing, perspiration and rubbing, while ink‐jet‐printed fabrics show better colour fastness to dry‐cleaning and light. The fabrics printed with both printing techniques have high rigidity and non‐elastic properties. The mechanical and physical parameters are strongly dependent upon the amount of the dry substance of the printing media applied on the cotton fabric surface, which is higher on screen‐printed fabrics. The ink‐jet‐printed fabrics show better air permeability than flat‐screen‐printed fabrics.     

The application of chitosan in pigment printing

The use of chitosan as a combined thickener and binder in pigment printing has been examined in comparison with a commercial printing system (Alcoprint). Printing pastes made up from mixtures of chitosan, pigment and acetic acid at the appropriate viscosity gave satisfactory prints on polyester and 67:33 polyester/cotton woven fabrics. Rheological data showed the chitosan pigment paste had a much lower yield point than commercial printing paste though no difficulties were found in its use. Curing of the chitosan print at 150°C for 6 min gave samples of comparable colour fastness to the commercial printed samples when subjected to the rubbing and washing tests. The only drawbacks noted in using chitosan in this way were a reduced colour yield and a much higher fabric stiffness.
