The application discloses a heat transfer printing method, system, printing control equipment and storage medium. By adopting a PET release film as a printing substrate and sequentially printing a color ink layer, a white ink layer and an adhesive layer with a specific formula, and then drying and heat pressing and transferring, pattern transfer to the fabric is realized, the pre-treatment process of the fabric necessary for the traditional DTG process can be completely abandoned, the technical problems of the existing technology, such as the strict timeliness of pre-treatment, strong operation dependence and large quality fluctuation, are fundamentally solved, meanwhile, defects such as uneven color, high defective rate and poor quality consistency caused by factors such as pre-treatment agent failure, uneven coating and fabric creases are avoided, the production process is simplified, the labor and material costs are reduced, the color uniformity, brightness of the printed pattern and the consistency of different batches of products are significantly improved, and a stable and reliable printing scheme is provided for industrialized mass production.

The application provides a pet robot personification performance method and device, relates to the technical field of data processing, and is applied to a pet robot.The method comprises the following steps: when the pet robot meets an autonomous roaming condition, the pet robot is controlled to enter an autonomous roaming state; in the autonomous roaming state, device environment information is acquired, object recognition is performed based on the device environment information, and a target recognized object is obtained; wherein the device environment information is acquired by an image acquisition device on the pet robot; based on the target recognized object, target personification performance data is determined, and the target personification performance data is executed to control the pet robot to display multi-modal personification performance on the target recognized object; wherein the target personification performance data comprises expression data, action group data and audio data.

This disclosure provides a method, apparatus, storage medium, and electronic device for generating water flow animation, relating to the field of computer technology. The water flow animation generation method includes: obtaining a basic water flow color for pixels based on a water flow map; determining a first offset value and a second offset value for the target frame based on time parameters of the target frame; obtaining water flow parameters based on the basic water flow color, and obtaining a first water flow color based on the water flow parameters and the first offset value, and obtaining a second water flow color based on the water flow parameters and the second offset value; mixing the first and second water flow colors using color mixing parameters to obtain a target water flow color for pixels in each frame; and generating the water flow animation based on the target water flow color of the pixels in each frame. This disclosure improves upon the problem of low efficiency in water flow animation generation.

The invention relates to a modified cotton fabric for improving biodye melanin absorption binding force and a preparation method and application thereof. The preparation method comprises the following steps: performing oxygen plasma treatment on a cotton fabric for physical modification; treating the physically modified cotton fabric with a cationic modifier for chemical modification; and performing enzyme treatment, namely biological modification, on the chemically modified cotton fabric to obtain the modified cotton fabric. According to the application, the modified cotton fabric obtained through the method is subjected to biodye melanin dyeing treatment. The modified cotton fabric is prepared through the physical-chemical-biological synergistic modification technology and the mutual cooperation of three modification means, the dyeing effect is improved in a synergistic interaction mode, the absorption capacity and binding force of cotton fibers to biological dye melanin are greatly improved, the dyeing depth and vividness are obviously increased, and the dyeing effect is improved. Various color fastness indexes reach or exceed the dyeing level of a traditional chemical dye, and the problem that the dyeing effect of biological dye melanin in cotton fiber dyeing is poor is solved.
