Taffeta

Acetate and triacetate are essentially unaffected by dilute solutions of weak acids, but strong mineral acids cause serious degradation. The results of exposure of heat-treated and untreated triacetate taffeta fabrics to various chemical reagents have been reported (9). Acetate and triacetate fibers are not affected by the perchloroethylene dry-cleaning solutions normally used in the United States and Canada. Trichloroethylene, employed to a limited extent in the UK and Europe, softens triacetate. 

Very small quantities of acetate staple are dyed, however, large quantities of acetate filament are found in satin, taffeta, and tricot fabrics these are usually dyed open-width on a jig owing to thek inclination to crease or crack easily. A typical dyeing procedure on the jig involves addition of acetic acid and dispersing agent over two ends at 50°C. The disperse dye is added over two ends and the dyebath temperature is gradually raised to 80°C in 5°C increments with two passes at each temperature. The dyeing is completed after 30—60 min at 80°C. 

Leave us, she commanded, and the women rose in a rustle of taffeta. The maid curtseyed and hurried to open the door. The lady companion nodded with no comment and a completely expressionless face, although including her in the same command as the servant had to be a deliberate discourtesy.

Fabricio returned, scooped up the portmanteau, and led me upstairs. Since my last visit the landing at the mezzanine level had been furnished with three marble busts and the fair madonna Grazia, she of the divine eyes and devilish nose. Her gown was a glittering mist of silver taffeta and pearls, her hair had been set in a much less childish style than before, and only time would ever make her look like an adult. 

Non-ravel bonding In this application the REZTHANES have been applied to a wide variety of fabric from single ply taffeta to 400d. pack cloth without detracting from the hand of the goods. 

Produces clear, high luster finish for acetate ribbon fabrics and taffetas. Does not require curing. 

Resin finish for acetate ribbons, satins, and taffeta where a crisp hand is desired. Produces a clear, high luster finish. 

However applied, these products can be used to stabilize weave and to impart special finish effects to fabrics made of cotton, wool, synthetic fibers and filaments, and to mixtures. Treatment gives outstanding finishes on nylon and Dacron marquisettes, rayon linings, satins, taffetas, ribbons, rayon and wool blends, fiberglass fabrics and viscose rayon suitings. Application requires no special equipment and no curing. 

The electrolyte should contain 40-60 g./liter of Zn (calculated as the sulfate). A piece of silk taffeta serves as the membrane. Pure ZnO is suspended by stirring in the anode chamber. The cathode is A1 or Pt, the anode is Pt. The current density is 0.01-0.03 amp./cm. The Zn deposit may be peeled off cleanly from the aluminum sheet by cutting off its edges. Inclusions are removed by fusing with a small quantity of NH4CI in a porcelain crucible. The ingot is pickled clean with HCl and thoroughly washed with distilled water.

Taffeta ta-fo-t9 [ME, fr. MF taffetas, fr. Olt taffeta, fr. Turkish tafta, fr. Persian taftah woven] (14c) n. A plain-weave fabric with a fine, smooth, crisp hand, and usually a lustrous appearance. Taffeta fabric usually has a fine cross rib made by using a heavier filling yarn than warp yarn. Taffetas are produced in solid colors, yarn-dyed plaids and stripes, and prints. Changeable and...

Taffeta ribbons are filament yam ribbons, with a plain or check patterned, for ribbon bows. 

The fabrics (53 x 48 connt/cm, 140 g/m taffeta fabric) were used as substrate. The surface area of each specimen is 100 cm. The electroless copper plating process was conducted by multistep processes pre-cleaning, sensitisation, activation, electroless Cu-Ni-p alloy deposition, and post-treatment. 

Chameleon ko- mel-yan n [ME camelion, fr. MF, fr. L chamaeleon, fr. Gk chamailedn, fr. chamai on the ground -f Icon lion] (14c) A variable multicolored effect achieved hy using warp yams of one color and two filling yams of different colors in each shed. It is sometimes used in taffeta, faille, or poplin made from silk or manufactured filament yams. 

An explanation for this inereased energy transfer is that tlie specific heat of steam/air mixture is almost twice of that of air alone. Also by using steam/air mixture, heat exchange at the exterior of the fiber is increased, but the heat conduction from the surface to the interior of the fiber remains imchanged. Thus warp knitted fabrics and lightweight woven like taffeta and georgette require 3-4 seconds with steam/air mixture, compared with 15 seconds if hot air alone is used. Heavier fabrics, especially woven require 9 seconds with rapid heat setting (with steam/air mixture) and 30 seconds with hot air. 

Vegetation-based textiles are more wide-ranging. Grasses, straws, bamboos, pulp-wood trees, cotton plants, rice, milkweed, and nettle are prime sources of bulk and/or (bast) fibers for textiles. Acetate is introduced to increase the reflectivity of certain vegetative fabrics such as artificial silk and taffetas. Seaweed and alginate fibers can comprise certain specialized textiles, while other more unique manmade fabrics such as lyocell are constructed from blends of cotton and wood fibers.
