The application discloses a preparation method of a cotton-feeling polyester fabric. The application relates to the technical field of polyester fabric processing, and provides a preparation method of a cotton-feeling polyester fabric which has the characteristics of softness, comfort, wear resistance and wrinkle resistance. The method comprises the following steps: S1, preparing parent yarn; S2, air-textured yarn treatment; two parent yarns are fed into an air-textured yarn processing device, the nozzle air flow pressure is set to be 0.3-0.8 Mpa, and the nozzle temperature is set to be 80-120 DEG C; in the two parent yarns, the overfeed rate of low-overfeed parent yarn is set to be 5-10%, and the overfeed rate of high-overfeed parent yarn is greater than the overfeed rate of low-overfeed parent yarn by more than 5%; air-textured yarn is prepared; S3, weaving; the air-textured yarn is woven into a fabric; and S4, post-finishing; the woven fabric is subjected to biological enzyme treatment, alkali-reducing treatment and softening finishing.

This application relates to a method for switching headphone operating modes, a headphone, a computer-readable storage medium, and a computer program product. Applied to headphones, the headphones include a vent valve and an active noise cancellation module. The method includes: acquiring head posture data; adjusting the operating state of the vent valve and the active noise cancellation module based on the head posture data to switch the current operating mode; wherein the vent valve is used to allow or restrict external ambient sound from entering the ear; the active noise cancellation mode neutralizes the ambient sound through reverse sound waves. Using this method, on the one hand, switching headphone modes does not require physical contact with the headphones or through a mobile device application, greatly simplifying the operation process and improving operational convenience and efficiency. On the other hand, it achieves a balance between noise cancellation and wearing comfort in the headphones.
