S-119 is used for the control of migration during pad dyeing of fabrics.

Use of heteropolysaccharide S-119 as an antimigrant

A method of printing using polysaccharide gum S-88 as a thickening agent for printing pastes has been developed. The S-88 gum is gellable in the presence of about above 6% to 50% electrolyte. The gelling characteristic of the gum is useful in both single- and multi-phase print systems. The single-phase print system uses a print paste composition containing the S-88 gum together with about 1-6% concentration of electrolyte which, when applied to a substrate, and when the overall moisture content drop (by such methods as heating, etc.) results in a concomitant increase in electrolyte concentration sufficient to cause gelation. The multi-phase print system uses the electrolyte in one phase and the gellable gum in another; i.e., the electrolyte-containing paste or solution with concentration of 6-50% electrolyte is either impregnated on or in the substrate or is present in the printing paste which is applied before or after the S-88 gum-containing paste.

TKP is used for the control of migration during pad dyeing of fabrics.

Use of TKP as an antimigrant

S-119 is used as a warp size for textiles, either alone or as an additive with other sizes such as starch, polyvinyl alcohol, CMC, etc.

Use of heteropolysaccharide S-119 as a warp size

Cationic or certain anionic dyes are rendered compatible with normally incompatible anionic and nonanionic polymers by the addition of certain surface active agents.

Dyeing composition and method

Novel blends of algin and TKP are disclosed. The blends are useful in commercial gum applications where thickening, suspending, emulsifying, stabilizing, film-forming, and gel-forming properties are needed. They are particularly useful in the paper and textile industries.

This invention relates to a deacetylated borate-biosynthetic gum or a partially deacetylated borate-biosynthetic gum having improved dispersion characteristics. The invention also relates to a method of preparing such compositions.

Deacetylated borate-biosynthetic gum compositions

A series of novel amphoteric graft copolymers of xanthomonas hydrophilic colloid and partially N-aminoalkylated acrylamide has been prepared by reacting the corresponding acrylamide copolymer with an alkyl amine and an active aldehyde. The new copolymer is cationized via acidification or quaternization, and is reverted to its anionic form via basification.

A water-soluble anionic graft copolymer of xanthan gum and polyacrylamide wherein at least part of the amide function is sulfomethylated.

Sulfomethylated graft copolymers of xanthan gum and polyacrylamide

A blend of xanthan gum, guar gum, or guar gum derivatives, a starch ether has unique thickening properties. The blend is particularly useful in printing pastes, salad dressings and oil well drilling muds.

Thickening compositions containing xanthan gum, guar gum and starch

Sodium cellulose sulfate can be used alone, or in combination with other natural or synthetic gums, as thickening agents for fabric printing paste compositions containing acid dyes. The printing paste is applied in the usual manner, and then the printed goods are heated. The sodium cellulose sulfate content of the paste, upon heating, fixes the acid dye on the printed goods, thereby eliminating the necessity of using acid or acid salts in printing pastes.
