Cellulose blending

Disperse liquid brands of sulphur, vat or disperse dyes, including mixed formulations of disperse and vat dyes in matching hues for the dyeing of polyester/cellulosic blends, have been commercially available for many years. The proportion of reactive dyes marketed as aqueous solutions is expected to increase markedly [10] because of ... 

Considerable research effort has been devoted to developing a new generation of disperse dyes designed to optimise fastness to washing and minimise cross-staining of the cellulosic component of polyester/cellulosic blends [97,98]. Diester-containing monoazo disperse dye structures (4.91) that yield a dicarboxylic acid on hydrolysis and certain thienylazo blues... 

Dye Combinations. In certain cases it is desirable to print fiber blends with combinations of the appropriate dye classes, rather than with pigments. Only polyester-cellulose blends are of commercial importance and the following dye systems have been developed for them. The dyes of the different classes are contained in the same print paste and, therefore, are applied simultaneously in one print operation. They include disperse-reactive combinations, disperse-pigment combinations, and disperse-vat combinations. 

The leuco esters of vat dyes are anthraquinoid or indigoid vat dyes (Section 3.4) that have been made water soluble by reduction and esterification of the hydroxyl groups with sulfuric acid. These dyes are used mainly for dyeing high-quality articles of cellulose fibers in light colors and polyester-cellulose blends to moderate depths of shade [58], [59, p. 568],... 

The most important fiber blends consist of polyester and cellulose fibers or wool. Of the worldwide consumption of PES fibers, ca. 45 % is used in blends with cellulose fibers. In polyester-cellulose blends the cellulose component is usually cotton or viscose staple fibers The preferred mixing ratio is PES CEL 67 33 and, for textiles worn close to the skin, 50 50 to 20 80. 

In the preparation of the cellulose blends listed above, two methods were mainly adopted casting from solutions by evaporation of solvent, and coagulation of solutions in a non-solvent followed by drying. Both processes involve dissolution and mixing of two polymer components in a common sol-... 

FKuR also introduced Biograde 200C in 2005, an unfilled cellulose blend with high stiffness and transparency for cast film and injection moulding. The material can also be blow moulded into bottles and thermoformed into cups and trays. Injection moulded Biograde 200C exhibits properties comparable to polystyrene, but with the addition of barrier performance comparable to PLA. It consists of 100% renewable resources, but does not contain starch. 

Crystalline cellulose, hydroxypropyl cellulose, and Carbopol 934 have been studied in combination with lyophilized insulin as bioadhesive powder dosage forms for nasal delivery. Each formulation tested resulted in an decrease in plasma glucose level after nasal administration in dog and rabbit models. The most effective formulation, crystalline cellulose blended with insulin, decreased the plasma glucose level to 49% of the control value. In ternary systems the lyophilized Carbopol 934 and insulin blend with crystalline cellulose powder has been the most effective, leading to a hypoglycemia on the order of one-third of the effect obtained after intravenous injection of the same dose of insulin. The plasma glucose levels obtained in the volunteers after administration of the insulin-Carbopol-crystalline cellulose powder formulation were quite variable [38],... 

Multi-purpose non-foaming dyeing assistant for jet dyeing of polyester/cotton blends. Also, used in other dyeing procedures of polyester/cellulosic blends when foaming is a potential problem. REMOL NFE is also very well suited for afterscouring. 

FIXAPRET PEC is a 45% aqueous solution of selected reactant compounds of the N-methylol and O-methylol range. The product was specially developed for the resin finishing of polyester/ cellulosic blends. 

FIXAPRET PEC imparts a very elegant, flowing handle, particularly to polyester/cellulose blends. 

Glyoxal reactant. Recommended for durable press finishing of synthetic/cellulose blends. Treated materials have high crease retention and excellent performance ratings. 

POMOCO SR 92 is a very versatile product, used on polyester and polyester/cellulosic blends as a dyebath detergent, a dye-bath lubricant, and as a finishing agent. 

MYKON EJ softener is very effective when used with permanent press resin finishes. It improves sewability and tear strength of cotton, rayon, and polyester/cellulosic blends without effecting chlorine resistance, lightfastness or scorch resistance of the finished fabric. MYKON EJ emulsion also softens the treated fabric. 

Handbuilders for cellulosic and synthetic/cellulosic blends WARCOSET CHB polymer does not contain formaldehyde. When used with low formaldehyde resins it does provide a resilient finish on rayon and polyester/rayon blends similar to that obtained with high formaldehyde resins. WARCOSET CHB solution is compatible with most commonly used finishing agents. 

Erionyl [Novartis], TM for a group of condensation products of aromatic sulfonic acids used as fixative/reserving agents in dyeing nylon and nylon-cellulosic blends.
