Spray dyeing

Metallized dyes, for example, are used to dye, or correct the hue of the surface of leathers which have not been drum dyed and to match it to the hue of the finish. As a result, damages to the finish in the course of the use of the leather article are less pronounced.

Leather Dyeing Methods and Equipment. The methods used in dyeing leather are quite simple and they obtain their names from the equipment employed, such as drum, wheel, paddle, brush, tray, or spray dyeing. Most leather is dyed in drums.

In a second test of spray pattern, special slides were obtained from Erie Scientific, Inc. (Portsmouth, NH) that were evenly coated over their entire surface with a paint-like coating that does not make fluids bead up, nor does it allow bleeding of applied fluids. These slides were loaded onto the platen, and the instrument was programmed to spray dye onto all three positions of each slide. The slides were then kept on the machine until all water had evaporated, leaving the dye residue on the coating in the original area sprayed. This test resulted in circular spray patterns over... 

Silk yam is normally degummed in the hank form. In the pack (beck), the hanks are normally hung on polished wood or metal rods which are submerged in the bath and turned by hand. Alternatively, hank and spray dyeing machines can also be used for degumming of silk in yam form. In the foam boiling process foam produced by soap bath comes m contact with silk and thus causes degumming.

Apparel leathers generally are not provided with a base coat. The pigment content in the pigment coat has been reduced in favor of the spray dyes in order that a more transparent, less coated appearance may be obtained for the finish. This is intensified by means of low concentration of the pigment finish and the large number of spray applications. At present, solvent-containing top coats are still customary for apparel leathers, but, as with shoe upper leather, there is an increasing trend toward the use of aqueous top coats. 

Uses. Tetrahydrofurfuryl alcohol is of interest in chemical and related industries where low toxicity and minimal environmental impact are important (134). For many years tetrahydrofurfuryl alcohol has been used as a specialty organic solvent. The fastest growing appHcations are in formulations for cleaners (135) and paint strippers (136), often as a replacement for chlorinated solvents (137). Other major appHcations include formulations for crop sprays, water-based paints, and the dyeing and finishing of textiles and leathers. Tetrahydrofurfuryl alcohol also finds appHcation as an intermediate in pharmaceutical appHcations. 

Stains. Nongrain-raising stains are usually sprayed overall and contribute the greatest to the overall undertone color of a finished piece. These stains are also sometimes referred to as body stains or overall stains. They are usually dye-type and can be formulated, depending on the type of dye powder and solvent system, to minimise the effect of the stain on the substrate. 

Carpet. Carpet, an important textile, may also be treated to provide water and oU repeUency however, the principal functions of the current carpet treatments are to provide soU and stain resistance. High quaUty carpets, especiaUy those made from nylon, polyester, or wool, have a significant proportion of the surface coated with fluorochemical materials. The treatments can be spray-appUed to a finished carpet or appUed directly to the fiber during the spinning or dyeing operations. Suitable fluorinated resin materials are readily avaUable from 3M or DuPont. 

The NF and reagent grades are employed in the pharmaceutical industry which makes use of benzyl alcohol s local anesthetic, antiseptic, and solvent properties (17—20). It also finds use in cough symps and drops ophthalmic solutions bum, dental (21), and insect repeUant solutions and ointments and dermatological aerosol sprays. It is used in nail lacquers and as a color developer in hair dyes by the cosmetics industry (22), and in acne treatment preparations (23). 

The most popular coloration method is to apply the dyes continuously, usually by padding, but printing, spray jet, and droplet appHcations are used. In order to obtain patterned effects, chemical or physical resisting agents can be appHed first, and deep and normal dyeing nylon and basic dyeable nylon blends can be used. In the latter case the basic dyeable nylon is dyed with cationic dyes. Carpets can be printed in an analogous method to other textiles and this process is more popular in Europe than the continuous appHcation techniques used in the United States. 

Later it was found growing in South America where the Indians used the red dye from the seeds as a body paint. An extract of the seeds appears on the market as annatto. This extract is used in coloring butter, margarine, and cheese such as Leicester cheese. In Mexican and South American cuisine, it finds special use as a flavor and coloring matter. The seeds are sold under the name achiote in many Latin grocery stores and markets. Ann at o is available as an aqueous solution, as an oleaginous dispersion, and a spray-dried powder. 

Natural dyes processed for the market do not undergo any chemical operations. Those operations iavolved are purely physical, such as grinding, spray or vacuum dryiag, and water or solvent extractions. None of these operations create any great environmental problems.
