This paper studied the metachrome process of an optimal dyeing method by comparing the color and fastness of walnut peel extract applied on the pearl fiber with ammonium ferrous sulfate as mordent. In addition, the paper also ascertained the reasonable dyeing process, that is, pH 9, walnut peel extract (the dye) dosage 200 ml/L, mordant (ammonium ferrous sulfate) 2.5 g/L, temperature 80 °C, time 60 min and liquor ratio 1:30, through analysis on single-factor experiments and orthogonal experiments by taking K/S as an evaluation index for the dyeing effect. The results showed that a better effect is achievable by dyeing the pearl fiber with walnut peel dye through the metachrome process.

A novel functional disperse dye doped with graphene oxide for antistatic properties of polyester fabric was achieved, which means that the dyeing and antistatic finishing can be simultaneously obtained by a one-bath method. Functional dyes were used to dye polyester fabric by a high-temperature, high-pressure dyeing method. The surface microscopic morphology of the dyed polyester fabric, and the dispersion properties of the disperse dye, graphene oxide, and the functional disperse dye, were characterized by scanning electron microscopy. The effects of the dyeing temperature on the particle sizes of three dyeing liquors were explored; this revealed that the temperature of the dyeing process had no effect on particle size. The dosage and reduction time of graphene oxide were investigated. The surface electrical resistance of the dyed fabric, 9.8 × 106 Ω, obtained at a condition of 2% (o.m.f) graphene oxide with a reduction time of 30 min, achieved A-grade antistatic standard. Furthermore, the rubbing and washing fastness of the treated fabric were 4- and 4 ∼ 5 grades, respectively. This preparation of the functional disperse dye provides a possibility in one-bath dyeing and antistatic finishing of polyester fabric.

This study presents experimental investigations on the mechanisms of the repeatability of positioning of linear axes of computer numerical control machine tools. First, the factors affecting the repeatability of positioning of linear axes are obtained based on orthogonal experiments. Second, the mechanism of each factor affecting the repeatability of positioning is studied based on single-factor experiments. Finally, an assembly method to improve the repeatability of positioning of linear axes is proposed. The method can provide designers and workers with informative guidelines for improving the repeatability of positioning in design and assembly processes.

Using ethanol as solvent, reflux extraction of aloetic anthraquinone compounds was studied. The single-factor orthogonal experiments were conducted to optimize extraction process and the extractive was identified using infrared spectroscopy. The results suggested the best extraction conditions: ethanol concentration 70%, extraction temperature 333.15K, extraction time 25 min, bath ratio 1:1.5. This simple and effective extracting method is in accord with current energy-saving, environmental protecting trends, and its product has wide application prospects for preparation of health-care textiles.

For the practical application of dynamic holography using updatable dyed materials, optical transparency and an enlarged sample size with a uniform dispersion of the dye and no air bubbles are crucial. The holographic films were prepared by applying a dyeing method comprising application, curing, dyeing, and washing to an unsaturated polyester (UP) resin film. The unsaturated polyester (UP) resin film with high optical transparency was dyed with a 3-[(4-cyanophenyl)azo]-9H-carbazole-9-ethanol (CACzE) (azo-carbazole) dye via the surfactant, polyoxyethylene (5) docosyl ether, in an aqueous solution. The amount of dye uptake obtained via the dyeing process ranged from 0.49 to 6.75 wt.%. The dye concentration in the UP resin was proportional to the dye concentration in the aqueous solution and the immersion time. The UP resin film with 3.65 wt.% dye exhibited the optical diffraction property η1 of 0.23% with a response time τ of 5.9 s and a decay time of 3.6 s. The spectroscopic evaluation of the UP resin film crosslinking reaction and the dyeing state in the UP resin film are discussed. Furthermore, as an example of its functionality, the dynamic holographic properties of the dye-doped UP resin film are discussed.

Cordyceps flower is a new resource as a food and drug, which has a broad market prospect. The paper using Cordyceps flower sporocarp as raw material and adopting sensory results as evaluation criteria, through single factor and orthogonal experiments optimize cordyceps flower beverage formula. The results show that Cordyceps powder should be first leached in a water bath at 80℃ for 15 min at a feed-liquid ratio of 1:30. After centrifugation and filtration, cordyceps flower liquid was obtained. Then the liquid should be reconstitute into 30% diluent. Third, adding 0.04% aspartame, 0.06% citric acid and 0.1% sodium carboxyl methyl cellulose (CMC), a tasty and nutritious cordyceps flower beverage was developed ultimately.

In this investigation dyeing of alginate fiber was carried out after cationic treatment of EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, breaking strength. Later in dyeing for fixation ferrous sulfate, copper sulphate was considered as mordents. Moreover using pre-mordanting methods conveyed the dyeing of alginate fiber with the stave of metallic mordant and without metallic salt mordents. The evaluation of each color dyed material was done through following two terms for instance CIELAB (L*, a*, and b*) and K/S values. According to AATCC test methods color fastness to washing of the dyed fiber was determined whereas according to the ASTM D3822M standard the breaking strength of alginate fiber was estimated and tested. When dyeing was carried out on alginate fiber through considering optimum parameter like 80◦C for 90 min, M: L 1:40 and at pH 7 which showed optimum results. In addition to mostly very good wash fastness was obtained while there was no fading of the color, whereas the moderate level of color fastness to crocking was achieved. Later after dyeing the evaluations of SEM of the cationized alginate fiber and FTIR of powder from the rhubarb dye were observed. The results suggested that the surface of cationized alginate fiber was smoother than the raw alginate fiber.

The main raw materials of rose milk beverage are Yunnan red roses and milk. By analyzing the proportions of rose juice to milk, sucrose, citric acid and sodium alginate, and by taking flavor, taste, color and tissue state as the evaluation parameters, we conducted single-factor experiments and orthogonal experiments, and identified the optimum formula of rose milk beverage: 8% rose juice, 6% milk, 10% sucrose, 0.1% citric acid, and 0.15% compound stabilizer (sodium carboxymethyl cellulose, sodium alginate in the proportion of 1:1). Unique flavor of rose milk beverage with rich nutrition can be prepared by using the optimum formula we obtained.

Two vegetable dyes of indigo naturalis and turmeric were combined on dyeing tussah silk fabric with two steps. The first step is dyeing the silk fabric with indigo naturalis by reduction process, and then dyed with turmeric by direct dyeing process. The results of single factor experiment on the indigo naturalis dyed tussah silk fabric dyeing with turmeric indicated that the relative concentration, pH value, dyeing temperature, and dyeing time had effect to a certain extent on the over dyeing. The dyeing conditions were determined by the above single factor experiment. The rubbing fastness and washing resistance of the dyed silk fabric could achieve to grade 3 more than grade 3.
