adopting the engraved roll pad for textile dyeing and finishing

the engraved roll pad $em dash$ long used in the paper and film industries $em dash$ can also be used to reduce wet pickup in textile finishing. the method uniformly and accurately applies liquor. by knowing the geometry of the roll, it is possible to calculate the volume of liquor applied per fabric weight. 5 refs

edible oil waste treatment surpasses requirements

the edible oils refinery at marks, mississippi manufactures edible oils from cottonseed and soybeans. in october of 1974, the plant was issued a permit which laid out effluent requirements to be met initially and after 2 years of operation (i. e. , by october 1979). this paper presents the results of design, construction, and operation of..

jet dyeing keys move to top-quality apparel knits

cleveland mills, lawndale, n. c. , is a leading supplier of dyed and finished polyester-cotton circular knit fabrics. cleveland uses disperse dyes for the polyester component and directs or fiber reactives for the cotton portion of the blend. dyeing takes place at 260 f maximum temperature with a minimum of chemical assistants in the bath..

dyeing of alkali swollen and alkali swollen solvent exchanged cotton with a reactive dye

in the reported experiments, an attempt was made to dye alkali swollen and alkali swollen solvent exchanged cotton with a c. i reactive blue 5 dye from the mixture of dimethylformamide and various nonpolar solvents. at a suitable dimethylformamide-nonpolar solvent ratio and alkali concentration used for cotton pre-swelling, it was possibl..

dyeing system compatible with present-day laundering habits

in all attempts to optimize dyeing and finishing processes, the vital point is to ensure that each individual treatment stage promotes smooth processing in the next. quite apart from the chemical and technical criteria that need to be met, the cost factor entailed can often be quite considerable. against this general background a new clas..

effect of gamma radiation on direct dye-cellulose interaction

the aim of this work was to study the effect of gamma-irradiation on the mode of interaction between cellulosic cotton and direct dyes. the study showed that: 1) gamma-irradiation of cotton cellulose decreases the dye uptake. 2) dyeings of irradiated cotton fabric with direct dyes have increased fastness of washing at the boil and soaping..

machinery for economically dyeing small lots

a compact range for continuous dyeing of small lots of cotton and cellulosic fibers was developed which minimizes dye loss on changeover, cleanup time and the amount of washing water in the range. also stressed in design was a minimum floor space requirement and maximum flexibility. the chemical pad includes similar design features. the s..

high temperature resistance of direct dyed cotton

in the course of this work dyeing of cotton with various types of direct dyes; vis. , diasazo, phthalocyanine and triazo, was performed under conditions prevailing for dyeing of polyester fibers the effect of accelerants and leveling agents on the coloration efficiencies of direct dyes on cotton was also investigated. 12 refs

behavior of chemically modified cellulose towards dyeing - 14 behavior of cotton and crosslinked cottons before and after mercerization towards some reactive dyestuffs

in the reported experiments, cotton fabric was crosslinked with dmdeu by applying the form d-process and form w-process. the cotton and crosslinked cotton were then treated with caustic soda solution of mercerizing strength. the ability of cotton and crosslinked cottons to dyeing with two reactive dyes, viz. procion blue mrb and procion r..

effect of counterions and ureas on adsorption of direct dye on cellulose

the differences in behavior on adsorption of direct dyes with different kinds of counterions on cellulose in the absence of an electrolyte are indicated, and an alternative role for electrolytes on adsorption of the dye on cellulose is proposed. in addition, an interesting effect of urea on the dye adsorption on cellulose at various tempe..
