摘要:
There is provided a process for manufacturing woven or knitted fabrics comprising modifying the woven or knitted fabrics by applying a skeleton triazine cross-linking reaction using a sericin fixing method of raw silk to enhance its shrink and crease resistance and shape stability and thereafter removing the sericin using a special scouring. The process for manufacturing a woven or knitted fabric, comprises the steps of finishing and treating raw silk and/or cellulose fibers by using a silk sericin fixing method; doubling and twisting thus finished/treated raw silk and/or cellulose fibers; weaving or knitting the doubled and twisted yarns; swelling the woven or knitted fabric forming a cloth by dipping it in a bath; and, scouring the woven or knitted fabric swelled in the bath with an enzyme whereby the woven or knitted fabric is provided with shrink and crease resistance and shape stability.
摘要:
An ink-jet printing process for printing textile fiber materials, wherein the fiber materials are printed with an aqueous ink comprising (I) at least one disperse dye, and (II) glycerol, said ink having a viscosity of from 5 to 20 mPas at 25° C., and wherein said ink is applied to the fiber material with an ink-jet print head comprising an ink supply layer (b) receiving ink from an external ink reservoir, said ink supply layer having a first side and a second side and comprising, a porous medium having a plurality of pores therein and a plurality of holes extending therethrough, so as to allow passage of the ink, allows for high speed printing and yields prints with good fastness properties.

New polyglycol compounds are provided which are amphoteric derivatives of polyglycol compounds containing (a) an aliphatic hydrocarbon residue containing 12 to 24 carbon atoms, which is bound to nitrogen, and (b) -(CH2-CH2-O-)k groups bound to nitrogen, where k is a whole positive number, the molecule containing in all 4 to 12 -CH2-CH2-O- groups, which polyglycol compounds are, on one hand, quaternated with organic halogen compounds and esterified with at least dibasic oxygen acids with formation of acid ester groups. The compounds of the present invention are especially useful as dyeing auxiliaries, and more particularly, as levelling agents for the dyeing of wool.

The present invention is directed to processes for colorization of molded articles made from engineering plastics. In particular, the processes are used to colorize ice skate blade holders and goalie skate cowlings.
摘要:
Quaternary ammonium salts were incorporated into anthraquinone dyes via a stable linkage. The structure of the antimicrobial colorants were characterized by Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR) and UV-vis spectrometry. The dyes demonstrated excellent antimicrobial ability against both gram-negative and gram-positive bacteria in aqueous solution, as indicated by very low minimum inhibitory concentration (MIC). The colorants showed excellent stability in water under light, continuous heating as well as acidic and alkaline conditions.

A process is provided for manufacturing a high quality cloth having a width of 150 cm or any width in which likelihood of occurrence of defects such as color shading, rub marks, wrinkles and creases due to fabric dyeing method is eliminated and color fastness is enhanced. A process for manufacturing a woven or knit fabric using yarn dyed silk comprises the steps of dyeing (step 3) sericin which covers the periphery of silk fibers and fibroin which is located inside thereof into the same color; making yarn dyed silk (step 4, 5) by doubling and twisting the dyed silk fibers; making a cloth (step 6) by weaving or knitting the yarn dyed silk swelling (step 7) the yarn, tyed silk which constitutes the cloth by dipping the cloth into hot water in a tub; and decomposing (step 8) sericin of the yarn dyed silk of the cloth with an enzyme in hot water in a tub.
