[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example: A graduation cap, such as Figures 1-4 As shown, the graduation cap body 1 includes a square cap top 2, a brim 3, and a tassel 4. Inside the cap top 2, there is a square shock-absorbing and breathable core 5. The shock-absorbing and breathable core 5 includes an inner layer 6, a shock-absorbing layer 7, and an outer layer 8. The inner layer 6, the outer layer 8, and the shock-absorbing layer 7 have the same side length. The shock-absorbing layer 7 is made of rubber injection molding. The rubber material has good elasticity and shape retention, which allows the shock-absorbing layer 7 to provide a certain cushioning effect during collision. It will deform during the collision, thereby reducing the force of the collision. At the same time, the shock-absorbing layer 7 can quickly return to its original shape after deformation, which has good shape retention.

[0023] like Figures 3-7 As shown, the inner layer 6 has several elongated raised strips 9 arranged on the side near the outer layer 8, and the outer layer 8 has several elongated raised strips 10 arranged on the side near the inner layer 6. Both the inner layer 6 and the outer layer 8 are made by feeding high-elastic yarn 17 into an air-jet loom and weaving it with raised strips. Several raised strips 9 are integrally formed on the inner layer 6 by the raised strip weaving method, and several raised strips 10 are integrally formed on the outer layer 8 by the raised strip weaving method. Several through grooves 11 are formed between several adjacent raised strips 9 and the inner layer 6, and several through grooves 12 are formed between several adjacent raised strips 10 and the outer layer 8.

[0024] like Figures 1-6As shown, several through-slots 11 and several through-slots 12 intersect perpendicularly. A ventilation slot 13 is formed through the middle of the anti-collision layer 7. The inner layer 6 with a protrusion 9 and the outer layer 8 with a protrusion 10 are respectively glued to both sides of the anti-collision layer 7, so that the gap between the several through-slots 11 and several through-slots 12 and the ventilation slot 13 forms a ventilation space 14. The ventilation space 14 can provide a buffer and deformation distance for the anti-collision ventilation core 5 when it collides, further enhancing the anti-collision effect of the graduation cap body 1. Several ventilation holes 15 and several ventilation holes 16 that communicate with the ventilation space 14 are respectively formed through the inner layer 6 and the outer layer 8. A series of air vents 15 are arranged on the bottom surface of the through groove 11, and a series of air vents 16 are arranged on the bottom surface of the through groove 12. The air vents 16 and the air vents 15 have the same diameter and are arranged symmetrically. The air vents 15 and the air vents 16 are formed by simultaneously drilling through the intersection of the through grooves 11 and 12 within the area of ​​the air groove 13 of the inner layer 6 and the outer layer 8 by a laser drilling machine. The interconnected air vents 15, air vents 16 and the air space 14 improve the air circulation effect on both sides of the anti-collision air vent core 5, so that the manufactured anti-collision air vent core 5 has a good air permeability.

[0025] like Figure 3 , Figure 4 and Figure 7 As shown, the high-elastic yarn 17 is made by spirally winding a first strand 18 onto a second strand 19 using a ring spinning machine. The first strand 18 is made by twisting flax fibers using a twisting machine, and the second strand 19 is made by twisting spandex fibers using a twisting machine. When the inner layer 6 and the outer layer 8 are bonded to the anti-collision layer 7, a certain tension is applied, so that the inner layer 6 and the outer layer 8 are driven by the elastic force generated by the stretching of the second strand 19 after being bonded to the anti-collision layer 7, thus forming a certain tension, thereby ensuring the flatness and support effect of the anti-collision and breathable core 5. Flax fibers have good breathability, so the inner layer 6 and the outer layer 8 have good breathability. At the same time, the inner layer 6 and the outer layer 8 made by the high-elastic yarn 17 are soft and comfortable, and can stretch and rebound together with the anti-collision layer 7, thereby further improving the anti-collision and breathability of the anti-collision and breathable core 5.

[0026] like Figure 1 , Figure 3 and Figure 8As shown, the outer peripheral wall of the anti-collision breathable sandwich 5 is covered with a breathable layer 21, and the breathable layer 21 and the brim 3 are both made by feeding the breathable yarn 20 into the air-jet loom and weaving by plain weave, the breathable yarn 20 is twisted by twisting machine by twisting two first strands 18, so that the breathable layer 21 and the brim 3 have good breathability, and the linen fiber has the characteristics of rapid moisture absorption and moisture dispersion due to its special porous structure, so that the doctoral cap body 1 can quickly absorb the sweat generated by the head when worn and quickly disperse, thereby providing comfortable wearing feeling.

[0027] Working principle: the anti-collision layer 7 made of rubber material has good elasticity and shape retention, and when the inner layer 6 and the outer layer 8 are glued with the anti-collision layer 7, a certain tension is applied, so that the second strand 19 in the inner layer 6 and the outer layer 8 can drive the inner layer 6 and the outer layer 8 to form a certain tension when the second strand 19 in the inner layer 6 and the outer layer 8 is stretched to produce a rebound force, thereby ensuring the flatness and supporting effect of the anti-collision breathable sandwich 5, the anti-collision breathable sandwich 5 can provide cushioning and deformation when colliding, thereby reducing the acting force generated when the doctoral cap body 1 collides, the inner layer 6, the outer layer 8, the breathable layer 21 and the brim 3 made of linen fiber have good breathability, and the air circulation effect of the two sides of the anti-collision breathable sandwich 5 is improved through the plurality of air holes 15, the plurality of air holes 16 and the breathable space 14, and the breathable space 14 can provide a buffer and deformation distance for the anti-collision breathable sandwich 5 when colliding.
