The washing pen is a kind of vanishing pen. Its main function is: after writing on the fabric with a pen, under certain conditions, after a certain period of time, the handwriting disappears naturally or by other means.
The way in which the washing pen disappears can be divided into three types: one is naturally disappearing, and is divided into 2 hours, 4 hours, 8 hours, and 12 hours using one day; and a little longer, such as one day,
Two days or even days. The other is the use of chemical reactions, mainly chemical indicators, such as hydrogen peroxide, oxidant reducing agent, etc., which is the mechanism of the redox reaction, so that the pH of the substance changes, so that the handwriting disappears under certain conditions. The last one is to use a conventional washing method to eliminate handwriting.
The research and development personnel of our center have concluded from the practical experience that each of the above three methods has its own advantages and disadvantages:
1. The way of relying on natural disappearance is greatly affected by environmental factors. For example, the difference in climate between the south and the north, the temperature and humidity are different, and the time of natural disappearance shows different changes. It is difficult to be controlled by people, and the human interference factor is small. The advantage is that it is very environmentally friendly.
2, the use of chemical reaction methods, the advantage is that it can meet people's wishes at any time, subject to the largest interference factors, and time is also very fast. The disadvantage is that the use of chemical substances, the way of chemical reaction, there is potential invisible damage; when the conditions change, it is possible to recover, there is a great instability.
3, using the conventional washing method, divided into two, one is the use of washing supplies, such as soap, washing powder, detergent, etc.; one is water washing, without adding any washing medium. The advantages of this method are: no time constraints, maximum randomness; no influence on climatic conditions; no return to the original; and no excessive chemical substances added, which is conducive to environmental protection and has a good prospect. (Strictly speaking, the ink used in the clear water can be removed without adding any detergent. It should be called hydrolyzed ink. This type of ink is more convenient to use and more environmentally friendly.)
Usually, customers have the following requirements for washing pens: (1) have a certain color fastness when combined with fabric (cloth); (2) can withstand the washing of appropriate amount of water; (3) are not affected by temperature and climate; (4) There is no diffusion on the fabric (cloth).
Washing pen belongs to a special purpose marker. It is widely used in textile, garment, shoemaking and embroidery industries. Its sales volume is increasing and it has become the new favorite of the pen industry. Among them, the washing ink is a special type of new ink, which has its own unique characteristics and has its own applicable field, instead of other inks.
At present, there are not many manufacturers of washing pen inks at home and abroad, and there are very few products that can meet the requirements of customers. Either the price is too expensive, or the quality is not up to the requirements, and there is very little that can really meet the needs of the market. We also want to see a lot of ink suppliers are actively working to develop, in order to change this situation. For the washing pen, it is not only required to be able to wash off the handwriting by the conventional washing method, but also to meet certain requirements in terms of color fastness and non-diffusion. Therefore, it also has considerable technical content. After several months of hard work, our technicians have developed two kinds of special inks for washing and hydrolyzing. The quality and characteristics of our products have reached and exceeded similar products at home and abroad, especially The second-class products are colorful and can meet the various needs of users. The products have been put on the market and have been well received by customers.
This article is the understanding of the internal research summary of our center, throwing bricks and jade, and the defects, please let us know. We hope to have more exchanges with the industry, so that everyone can understand in the special pen and special ink research and development field, and create a strong pen-making country with Chinese characteristics.
