JP5581592B2 - Inkjet dyeing composition set and inkjet dyeing method using the same - Google Patents

Description

The present invention relates to an inkjet dye-resisting method. More specifically, the present invention relates to a composition set for inkjet dye- resisting which has excellent bleeding and suppresses bleeding even on a fabric which has not been subjected to inkjet pretreatment, and an ink jet using the same. It relates to a dyeing method.

  A method for inhibiting dye fixation by adding a wax to the dyeing paste is known in the dyeing prevention field, as described in, for example, dyeing and finishing technology, Kazuo Shiozawa, Jinshoshokan, etc. Is the way. However, when an aqueous ink containing wax is directly ejected onto a cloth that is not subjected to inkjet pretreatment, an image is formed on the cloth. For this reason, the inkjet pre-processing which usually provided the component which consists of water-soluble high molecular compounds, such as carboxymethylcellulose and sodium alginate, to the fabric has been performed (for example, refer patent document 1). In this method, it is considered that the water-soluble polymer compound in the fabric has acted as an ink-holding component (absorbing layer) to prevent bleeding.

  Unlike the ink jet printing process that can be handled on demand, such a pretreatment for ink jet of a fabric needs to be processed in a certain amount in advance. Therefore, it takes a lot of time and the pretreatment cloth Since it has inventory and processing cost, it has become a big obstacle in spreading inkjet printing more.

  In addition, as described above, by applying a paste to the fabric, it is easy to stay on the fabric surface due to the mechanism that suppresses bleeding by absorbing the ink. There is also a problem of not being dyed.

As an attempt to eliminate pretreatment by applying a functional liquid for suppressing bleeding using an ink jet head, a method is disclosed in which an image is trimmed with a first ink containing a bleeding inhibitor (for example, a patent). Reference 2). In the method described in Patent Document 2, addition of a compound having a property of repelling water with a hydrophobic substance is disclosed as a bleed inhibitor, but it is possible to prevent bleed at the boundary between a white background and an image portion or to have a different specific hue. It is considered that the invention is limited to the prevention of blurring of the boundary. The method described in Patent Document 2 has a problem that it cannot cope with blurring suppression in a printed image having a gradation expression with increased expressive power. Also, it is not suitable for fine line and detail image expression. This is because the print area of the first ink and the print image of the second ink must be accurately matched, but the fabric is easily stretchable and the printing position is very difficult to align. Furthermore, since the first ink itself also bleeds into the fabric, very fine fine lines cannot be drawn in principle.
