摘要:
An improved method for imparting a tint or color to a soft, hydrogel contact lens by uniformly dispersing a dye throughout the lens. The dye is a water-soluble halotriazine dye. The dye is reacted with a hydrophilic monomer to prepare a reactive dye containing predominantly monofunctionality. The monomer is then subjected to polymerization in the presence of a homogeneous solution of the reactive dye in the monomer under conditions to yield the hydrophilic polymer from which the lens is formed. The dye becomes bonded to the polymer during polymerization. The finished lens does not require soaking in an aqueous solution of the dye to impart the desired tint or color to the lens. Additionally, the dye uniformly dispersed throughout the lens according to the improved method does not leach out of the lens or migrate within the lens. Furthermore, the lens does not need to be washed with aqueous base to bond the dye to the lens.
摘要:
A dye which is durable for practical use in the field of coloring automobile seat materials for which a good light-fastness is required and a dyeing method making use of the dye is provided. In the method, a disazo dye is obtained by converting guanazole to a tetrazo compound and coupling the tetrazo with an indole derivative to form a compound which is then quaternized using e.g., an alkylating agent resulting in a red dye with superior light-fastness at high temperatures.
摘要:
Condensation products obtainable by condensation of a mixture comprising unsubstituted melamine, substituted melamine and hydroxyphenyl compounds with formaldehyde or formaldehyde donor compounds are dyed in the form of fibers, yarns, threads, wovens, knits or nonwovens in an aqueous liquor with one or more dyes of the class of the azo, anthraquinone, coumarin, methine, azamethine, quinophthalone or nitro dyes.
摘要:
Disclosed herein is a multi-color printed nonwoven laminate and a process for producing the laminate. The laminate includes a fibrous nonwoven web facing layer and a substrate layer bonded to the facing layer by a plurality of colored adhesive inks applied in a discrete bond pattern between the facing and substrate layers. The inks must provide a cohesion strength between the layers of at least about 38,000 N/m.sup.2 and the inks must be visible through the surface or the facing layer. The laminate so produced has good delamination characteristics, is aesthetically pleasing and the printed patterns are resistant to abrasion due to the position and nature of the inks. Suitable uses include an outercover for personal care absorbent articles such as diapers, training pants, incontinence garments, sanitary napkins, bandages and the like as well as a material for use as all or a portion of an article of clothing or a surgical drape.

摘要:
A process for dyeing textile fiber materials with water-soluble dyestuffs, in particular anionic dyestuffs, and of these in particular those having a fiber-reactive group, in which the dyeing is carried out using low-electrolyte or entirely electrolyte-free and/or low-alkali or entirely alkali-free dye liquors or printing pastes and a fiber material which has been modified with a silane compound containing amino groups is used as the textile material. The fiber material is modified by applying the silane compound containing amino groups to the material in aqueous solution and subjecting the impregnated material to a heat treatment. Novel silane compounds which contain a secondary amino group and can likewise be employed for the purpose mentioned are furthermore described.
