Problems solved by technology

[0002] After the traditional nylon carpet is digitally printed, in order to better retain the vividness of the printed color and prolong the printing retention time, it is necessary to carry out a color-fixing process after printing. The nylon carpet is soaked in a fixed chemical solution for a period of time. Time, and then washing, drying and other processes, the process is complicated, and requires a large area of ​​work space and unchangeable soaking time, which seriously affects the production efficiency and cannot be completed in time when there are many orders

Abstract

The invention relates to the technical field of spinning, and particularly relates to a formula of a disposable agent for digital printing of a nylon carpet and an application thereof. The formula of the disposable agent for digital printing of the nylon carpet is characterized by comprising the following raw materials by weight percent: 20-40% of amino-modified organic silicon, 15-20% of tricarboxylic acid, 5-10% of water-soluble epoxy crosslinking agent terephthalic acid (EPTA) and 30-60% of water. Compared with the prior art, about more than 70% of softening agent taking the amino-modified organic silicon as a main body is prepared from a copolymer of N-beta-aminoethyl-gamma-ammonia propyl methyl dimethoxy silane and dimethyl siloxane as an active component. An active amino group is contained, so that the friction force between textile fibers can be reduced by the polarity, the formula is stable in size, good in drapability, and anti-pilling, and can restore after being folded. Tricarboxylic acid (PBTC) is a stabilizer with good performance, the colors printed on the nylon carpet can be well preserved, and the disposable agent has a good fixation effect.
