摘要:
Polyesteramines with good dye affinity for anionic dyestuffs formed by reactingA. at least an aromatic dicarboxylic acid and possibly a small amount of an aliphatic diacid,B. at least a diol having at least 3 carbon atoms such as an aliphatic, a saturated alicyclic or a cycloaliphatic diol, andC. at least a compound of the formulaNR.sub.3where R, being the same or different, is alkyl, saturated alicyclic, cycloalkyl or arylaliphatic, or where two R groups form a cycle between them.The NR.sub.3 compound has 1, 2 or 3 R groups containing 0, 1, 2 or 3 ester generating groups with the total number of ester generating groups being 1 to 3. The NR.sub.3 compound has no more than two R groups being arylaliphatic or cycloaliphatic which have only one carbon atom between the cycle and the nitrogen atom or being saturated alicyclic and there are at least 3 or more carbon atoms between the ester generating groups and the nitrogen atom.The total amount of the NR.sub.3 compound is present so that the percentage of nitrogen fixed on the polymer is at least 0.03% by weight of the polymer.Yarns made from these polyesteramines are used in a variety of textile applications.

摘要:
Articles made from polyesteramines such as filaments, fibers and molded products are dyed by treating the article with an alkylating agent in the form of a solution or emulsion in an amount of at least 1.5% by weight based on the weight of the article and at a temperature higher than room temperature for at least 15 minutes. The article is then dyed with a conventional anionic dye and preferably these two steps are carried out simultaneously.

Heading D1B Shaped articles of a minor proportion of a thermoplastic nitrogen containing basic dye receptor polymer and a major proportion of an inherently undyeable polyolefin or polyester are dyed by immersing the article in an aqueous dyebath containing an anionic dye and an acid, the amount of acid used being sufficient to cause at least a five-fold increase in dye uptake compared to when acid is absent and sufficient to obtain at least 55 % dyebath exhaustion, the acid being i) an aliphatic carboxylic acid having at least three carbon atoms, ii) an α-halo substituted aliphatic carboxylic acid, iii) a non-oxidising inorganic acid, iv) a compound which hydrolyses to an acid in water, v) acetic acid present in amounts of at least 400% o.w.f., vi) benzene sulphonic acid and vii) phenol. Preferably the article contains 0.5 to 10% of the thermoplastic nitrogen containing basic dye receptor polymer and the latter includes polyhexamethylene adipamide, polyhexamethylene sebacamide, polypyrrolidinone, polycaprolactam, polyenantholactam and copolymers of these, polyurethanes, polymer, polyvinylcarbazole, aniline-formaldehyde resins and polymers containing 2-vinylpyridine or 2- methyl-5-vinyl pyridine units. Polyolefins and polyesters used include polyethylene, polypropylene, poly(3-methyl-butene-1), poly(4- methyl-1-pentene) and their copolymers, polyethylene terephthalate, polyethylene terephthalate isophthalate, and poly(1,4-cyclohexylene-dimethylene terephthalate). Acid compounds used include nitrons, sulphurons, hydrochloric, propionic, hexanoic, glycolic, cyclohexylacttic, chloroacetic, dichloroacetic and α-bromopropionic acids and compounds which hydrolyse to give acids are aliphatic carboxylic acid alkyl esters, benzyl chloride, allyl bromide and p-nitrochlorobenzene.

An image forming method includes: applying a pretreatment liquid, which is an aqueous solution, to a cloth material, which is an absorbent base material; after applying the pretreatment liquid, applying an aqueous ink onto the cloth material to form an image on the cloth material by an ink jet method. Applying the pretreatment liquid includes applying the pretreatment liquid such that the cloth material includes, when applying the aqueous ink, the pretreatment liquid in an amount of 20 mg/cm2 to 150 mg/cm2 per unit area of the cloth material. The aqueous ink includes a white ink containing titanium oxide particles having an average particle diameter of 20 nm to 200 nm.
