Embodiment 1

[0039] This embodiment is an embodiment of the fungus-infected color-changing printing ink. The components and mass percentages of the bacteria-susceptible color-changing printing ink of the present embodiment are: 20% of bacteria-susceptible color-changing microcapsules, 3% of penetrating agent, 3% of thickener, 10% of softening agent, 5% of binder, Among them, three mixtures of gelatin, chitosan and sodium alginate are used as the capsule material of the bacterial-susceptible color-changing microcapsule, and capsanthin is used as the capsule core.

Embodiment 2

[0041] This embodiment is an embodiment of a towel containing a bacteria detector. The towel in this embodiment includes a towel body and a bacteria detector printed on the towel body; the bacteria detector is a printing pattern printed in the middle of the towel body, and the printing paste adopts the bacteria-inducing color-changing printing of Embodiment 1 ink.

[0042] The printing pattern in this embodiment adopts a flat screen printing process; the printing speed is 15-25 m / min; the drying temperature after printing is 150-180° C., and the drying time is 2-6 minutes.

[0043] When the user wrings out the towel, the fabrics of the towel will squeeze each other, destroying the capsule material of the bacterial-susceptible color-changing microcapsule on the bacteria detector. After the capsule material is destroyed, the coated capsanthin is released. When the number of bacterial colonies in the towel reaches a certain amount, the oily substance secreted by the bacteria rea...

Embodiment 3

[0046] This embodiment is the preparation method of the bacterium-infected color-changing printing ink of embodiment 1, specifically comprises the following steps:

[0047]Step 1: preparing an aqueous capsule material solution: using a mixture of chitosan and sodium alginate as a capsule material, fully stirring and mixing with water at a mass ratio of 1:30 to prepare an aqueous capsule material solution;

[0048] Step 2: Prepare O / W microcapsule suspension emulsion: mix capsanthin with the capsule material aqueous solution obtained in step 1 at a mass ratio of 1:5, then stir at high speed to emulsify capsanthin and capsule material aqueous solution, The emulsification and stirring time is 30 minutes, and then stand still for 0.5 hours, so that the capsule material is coated with capsanthin, and an O / W microcapsule suspension emulsion is obtained;

[0049] Step 3: Prepare microcapsule fixation solution: fully mix glutaraldehyde, glyoxal and water at a volume ratio of 1:1:3 to ...

Abstract

The invention discloses bacteria-sensitive color-changing printing ink, which comprises an osmotic agent, a thickening agent, a softener and an adhesive and also comprises a bacteria-sensitive color-changing microcapsule. The capsule material of the bacteria-sensitive color-changing microcapsule is a natural polymer material, and the capsule core is a fat-soluble pigment. The invention also discloses a manufacture method of the bacteria-sensitive color-changing printing ink and a towel containing a bacteria test meter. By the characteristic of the fat-soluble pigment, especially a tetraterpeneorganic derivative which is insoluble in water but soluble in fat substances secreted during metabolism of bacteria and is chromogenic, the fat-soluble pigment is used as a component of the fabric printing ink in the form of microcapsule so as to form the bacteria-sensitive color-changing printing ink. Fabrics printed by the use of the bacteria-sensitive color-changing printing ink, such as a towel, have the bacterial detection function. Thus, the number of bacterial colonies on fabrics is monitored, users are guided to disinfect and sterilize or replace towels, and diseases caused by bacteria are prevented.

Description

technical field [0001] The invention relates to the technical field of textile printing, in particular to a bacterium-infected color-changing printing ink, a manufacturing method thereof, and a towel containing a bacterium detector. Background technique [0002] In the environment we live in, bacteria are actually everywhere. The immune function of the human body enables us to resist external bacteria, so as to reduce the impact of bacteria on our body. The immune ability of the human body is limited. When exposed to too many bacteria, the bacteria will become the cause of human disease. However, no amount of bacteria can be recognized by our naked eyes. How to monitor whether the number of bacteria on the items we touch has reached the dangerous number of disease-causing, especially the items that are easy to breed bacteria in our daily contact, such as towels, to remind us Pay attention to keep clean and hygienic. However, in the existing textile products such as towels,...
