摘要:
The present invention is to provide a method and an apparatus for overcoming complication of the pretreating process due to diversification of materials by digitalizing a method for pretreating a fabric in an inkjet printing process by using an inkjet device, and further, an inkjet printing method and an inkjet printing apparatus for enabling the inkjet printing work to be continuously conducted on the basis of the said pretreatment. The present invention comprises a pretreatment liquid reservoir for enabling the pretreatment mixed liquid to be applied or respective containers to be filled with individual component compositions of a pretreatment liquid, a control unit for controlling application of the pretreatment liquid and a pretreatment head for applying the pretreatment liquid to the fabric, and it may additionally comprise a dryer for drying the pretreated fabric and a printing head for performing the actual printing work. The present invention can solve the problems incidental to the conventional pretreating method and further provide a method and an apparatus for enabling a continuous process to be executed.
摘要:
It is an object of the present invention is to provide fabric for use in ink-jet printing that can prevent not only “ink bleeding”, but also “white exposure”, “nonuniform coloration” and “back staining”. A further object of the present invention is the provision of fabric for use in ink-jet printing, consisting of two textures—napped and ground, which can be evenly ink-jet printed with no variation in color between both, while preventing the occurrence of “white exposure”, “nonuniform coloration” and “back staining”. Fabric for use in ink-jet printing composed of synthetic fiber or fiber containing synthetic fiber, consisting of two textures—napped and ground, the preparation of which comprises penetration of the ground texture with at least two types of solutions—one containing an ink holding agent of high wettability to synthetic fiber and the other containing an ink holding agent of low wettability to synthetic fiber, and penetration of the napped texture with a solution containing an ink holding agent of high wettability to synthetic fiber (represented as A in the same figure).
摘要:
A method to prevent the backstaining of denim during a stonewashing process comprising treating the denim with a solution or dispersion of a hydrophobically modified polymer having a hydrophilic backbone and at least one hydrophobic moiety, wherein said hydrophilic backbone is prepared from at least one monomer selected from the group consisting of ethylenically unsaturated hydrophilic monomer selected from the group consisting of amide, ether, alcohol, aldehyde, anhydride, ketone and ester; polymerizable hydrophilic cyclic monomer; non-ethylenically unsaturated polymerizable hydrophilic monomer which is selected from the group consisting of glycerol and other polyhydric alcohols; and combinations thereof, wherein said hydrophilic backbone is optionally substituted with one or more amino, amine, amide, sulfonate, sulfate, phosphonate, hydroxy, carboxyl or oxide groups; wherein said hydrophobic moiety is prepared from at least one hydrophobic monomer or a chain transfer agent, said hydrophobic monomer is selected from the group consisting of a siloxane, hydrophobic alkoxygroup, alkyl sulfonate, aryl sulfonate, and combinations thereof, and said chain transfer agent has 1 to 24 carbon atoms and is selected from the group consisting of a mercaptan, amine, alcohol, and combinations thereof, wherein said hydrophobically modified polymer is present in an amount of from 0.001 to 50 weight percent, based on the total weight of the solution or dispersion.
摘要:
A process for printing textile fiber materials in accordance with the inkjet printing process, wherein the fiber materials are printed with an aqueous ink, comprisinga) at least one reactive dye of formulae (1a) to (1j) as indicated herein, andb) 1,2-propylene glycol, N-methyl-2-pyrrolidone, an alginate or a water-soluble, non-ionic cellulose ether. The process is especially suitable for printing cellulosic fiber materials. The prints obtained have good fastness properties while having a high color yield.
摘要:
A substrate such as a woven or nonwoven fabric bound with a light-activated dye alone or in combination with additional conventional antimicrobial agents. The substrate is impregnated with a light-activated non-leachable dye having antimicrobial and/or antiviral characteristics which can be imparted to the substrate. The dye is bound by a cationic or anionic binder such as a water soluble polymer or carrageenan. Upon exposure to normal light, the dye generates singlet oxygen that kills microorganisms and viruses.
摘要:
There is disclosed a process for printing fibre material by the direct printing process, which process comprises printing the fibre material with a print paste comprising at least one dye, one cellulose derivative or alginate as thickener as well as further customary assistants and wherein the print paste comprises .ltoreq.5% by weight, based on the print paste, of a homopolymer or copolymer based on acrylamide.The novel process makes it possible to obtain strong patterned prints on a white ground which have good levelness, good fastness properties and sharp contours. The print pastes are distinguished by good homogeneity, good storage stability and simple handling.
摘要:
Open end spun cotton yarns are ring dyed with a thickened dyebath to limit dye penetration to the outer circumference of the yarn leaving a substantial undyed core. Stonewashed indigo dyed denim fabrics and garments are prepared.
摘要:
A jet ink composition for use with textiles which comprises a pigment dispersed with an acrylic resin, a silicone resin, and at least one non-aqueous solvent. The printed images formed therefrom resist subsequent dying and remain readable even after being subjected to dark-colored dyes.

The invention relates to certain highly substituted carboxymethyl sulfoethyl cellulose ethers (CMSEC), to a simplified and economic process for their production and to their use as thickeners in textile printing.
摘要:
A composition and its method of use are disclosed for controlling rheology of an aqueous dye, which composition comprises 1-30 parts of a gum selected from the group consisting of xanthan gum, rhamsan gum, welan gum and mixtures thereof and 70-99 parts of a water soluble polysaccharide having aliginate equivalent rheology, preferably an alginate. Also disclosed is a color imparting composition for fabric or carpet printing which comprises 99-99% of an aqueous dye component and 1-10% of the rheology control component. The polysaccharide is preferably an alginate, starch, cellulosic polymer or guar gum or mixtures thereof.
