摘要： A method of desizing, scouring and bleaching greige cotton/polyester fabrics containing colored portions constructed of yarns dyed with an excess of sensitive dyestuffs without incurring color markoff upon, or bleeding into the white background portions of the fabric. The dry greige fabric is first singed then quenched with steam or a water mist under conditions preventing a water pickup exceeding 30 percent of the fabric weight. The fabric is then passed through a multidip-type rope washer used as a treating chamber in which the solution contained therein is a hot alkaline solution of surface active agent held at 160*-210* F. and is at a solution to fabric weight ratio of 20-40:1. The motion of the fabric through the solution and alternate dipping and squeezing action of the solution through the fabric acts to scour, desize and remove excess dyestuff therefrom. After then washing thoroughly with water, the fabric is finally saturated with a peroxymonosulfate solution buffered at a pH of 5 to 8.5, then heated in the saturated condition at a temperature of 100*-212* F. to effect bleaching.

摘要： Textile washing and bleaching liquors are prepared by dissolving in water two aqueous liquid concentrates of which the first contains non-alkaline per-compounds, stabilizers therefor, and at least one non-oxidizable acid-stable organic nonionic and/or anionic detergent and the second contains washing alkalis, the two concentrates being used in amounts such that a liquor of the appropriate alkalinity, e.g. pH 9-10, for washing and bleaching is produced. In general, the second concentrate is always added before the first, and the goods may be given a preliminary wash with the liquor containing only the second concentrate before the first concentrate is added. The first concentrate may contain (a) as per-compounds, hydrogen peroxide, peroxyhydrated alkali metal borates, carbonates, phosphates, polyphosphates and phosphonates, and adducts of hydrogen peroxide with urea or with acetylated phosphites; (b) as stabilizers, acids such as phosphoric, polyphosphoric, sulphuric, hydrochloric, oxalic, benzoic, lactic, dipicolinic, quinaldic, quinolinic, ethylenediamine tetracetic, nitrilotriacetic, hydroxyethylethylenediamine triacetic and acetylated phosphorous acids, acid salts such as acid phosphates and polyphosphates, and bisulphates, and insoluble stabilizers such as magnesium silicate and meta-stannic acid; and (c) as detergents, ethylene oxide condensates with fatty alcohols, amines, acids, amides, alkanolamides and alkylphenols, condensates of protein hydrolysates with alkyl and alkylaryl sulphonic acids, soaps, alkylbenzene sulphonates, alkyl sulphates, fatty acid monoglyceride sulphates, fatty alkyl monoglyceryl ether sulphates and sulphonates, fatty esters or ethers of hydroxysulphonic acids, N-acyl derivatives of aminosulphonic or aminocarboxylic acids and fatty alcohol polyglycol ether sulphates. Cations if present may be sodium, potassium, mono-, di- or tri-ethanolamine or morpholine. A preferred detergent combination consists of a mixture of polyethylene glycol ethers and of similar ethers which have subsequently been condensed with propylene oxide. The second concentrate may contain, as washing alkalis, sodium, potassium or amine carbonates, phosphates, polyphosphates, silicates and acetates; as foam enhancers, alkanolamides, amides, alkylsulphonamides and alkylbenzenesulphonamides; as hydrotropes, toluene or xylene sulphonates; as solvents, methylcyclohexanol, polyethylene glycols, polyglycerols and ethers of glycols and glycerol with C1- 4 alcohols; as viscosity modifiers and dirt carriers, polyacrylate or polymethacrylate salts, carboxymethylcellulose, cellulose sulphate, cellulose sulphonic acids, polyvinyl alcohol or polyvinyl pyrrolidone; as activators, copper ions; as bactericides, formaldehyde or formic acid: and as corrosion inhibitors, chromic acid and chromates. The two concentrates may be produced in separate bottles or, suitably, in twin sachets or packages of liquid-impervious material. The liquor produced should preferably have an active oxygen content of 20-200, preferably 40-90 mg/l. and a detergent content of up to 5 g/l., preferably 0.5-4 g/l.ALSO:Textile washing and bleaching liquors are prepared by dissolving in water two aqueous liquid concentrates of which the first contains non-alkaline per-compounds, stabilizers therefor, and at least one non-oxidizable acid stable organic nonionic and/or anionic detergent and the second contains washing alkalis, the two concentrates being used in amounts such that a liquor of the appropriate alkalinity, e.g. pH 9-10, for washing and bleaching is produced.

摘要： A bi-regional fiber with a cellulosic core and a wax outer sheath is disclosed. The sheath can comprise high melting temperature wax. The fiber may be produced by processing the natural fiber at temperatures less than 70° C. The fiber can be processed in a standard manner such as, for example, a Keir process which may include bleach at approximately 100° C. with a wax subsequently added at a temperature sufficient to disperse the wax over the fiber surface. The fibers are ignition resistant as measured by industry standard tests. The wax may comprise from about 0.4 to 25 percent or greater of the fiber by weight. The wax may be natural wax, synthetic or emulsified wax or blends thereof. The bi-regional fibers can be blended with other fibers including BRCF fibers to create fire resistant fabrics including clothing, blankets and household materials.
