Abstract

The invention discloses a direct printing method of a low-temperature plasma processed fabric. The method comprises the following steps: firstly, finishing a fabric to be printed by low-temperature plasma processing equipment; fully coating a quaternary ammonium salt solution on the surface to be printed of the fabric by a sizing tool of a first color register in roll coating equipment or printing equipment; then orderly printing color pastes of other color registers on the surface to be printed of the fabric by printing equipment according to patterns designed in advance; and finally fixing, washing and sizing to obtain the finished product. An experiment indicates that compared with that of direct printing of a fabric which is not processed by plasmas, the apparent color yield K/S of direct printing of the low-temperature plasma processed fabric disclosed by the invention is improved by 10%-50%.

Description

technical field [0001] The invention belongs to the textile field and relates to a direct printing method for fabrics, in particular to a direct printing method for fabrics treated with low-temperature plasma. Background technique [0002] Among the current printing processes, direct printing is the simplest and most commonly used one. Direct printing is to print the printing paste directly on the fabric by hand or machine, so the characteristics of the fabric surface have the most direct impact on the printing effect. [0003] Plasma refers to a gas that is fully or partially ionized. The gaseous substance produces different degrees of separation of molecules and electrons under the action of energy such as heat and electricity, forming negatively charged electrons and positively charged ions. A mixed gas containing atoms, molecules, electrons, ions, photons, various metastable and excited state particles is called plasma. When the electron temperature (Te) is as high as ...
