4results about How to "Improve curling effect" patented technology

The present disclosure provides a curling accessory and a curling device comprising the same, and relates to the field of hair care equipment. The curling accessory comprises a ring body member and a connecting member. The ring body member has a ring-shaped channel and a plurality of outlets. The plurality of outlets are arranged along the circumference of the flow cross section of the ring-shaped channel. The connecting member has an air inlet that can guide fluid into the ring-shaped channel and flow out of the plurality of outlets. The fluid flowing out of the plurality of outlets blows towards the outer surface of the ring body member and forms an airflow flowing around the outer surface of the ring body member. At least part of the airflow flows around between the inner side and the outer side of the outer surface of the ring body member. In the above technical solution, the airflow flows around between the inner side and the outer side of the outer surface of the ring body member. Based on the Coanda effect, the hair can be adsorbed by the airflow and automatically wrapped around the outer surface of the ring body member along with the airflow to achieve automatic curling. The operation is simple and the curling effect is good.

The present invention relates to a method for preparing a crimped composite fiber and a crimped composite fiber obtained thereby, the method comprising the steps of: a) providing a composite fiber comprising a first component and a second component crimped side by side; b) subjecting the composite fiber in step a) to supercritical fluid infiltration; c) foaming and crimping the composite fiber subjected to supercritical fluid infiltration in step b); d) setting the composite fiber foamed and crimped in step c). The crimped composite fiber has improved fiber crimp shrinkage and warmth retention properties.

This disclosure provides a support component, a rollable display module, and a display device, relating to the field of display technology. The support component is used to connect to the backlight side of a display component to support the display component. The support component includes an integrally formed support plate, which includes a first support layer near the display component and a second support layer away from the display component. The first support layer includes a plurality of first support ribs spaced apart along a first direction, and the second support layer includes a plurality of second support ribs spaced apart along the first direction. Both the first and second support ribs extend along a second direction, which intersects the first direction. The spacing between two adjacent first support ribs is a first spacing, and the spacing between two adjacent second support ribs is a second spacing. The ratio of the second spacing to the first spacing is greater than 1 and less than or equal to 20. Furthermore, the ratio of the thickness of the second support layer to the thickness of the first support layer is greater than or equal to 1 and less than or equal to 10.

This utility model discloses a hemming machine for curtain production, relating to the technical field of curtain production equipment. The key technical points are: it includes a hemming machine body and a conveyor belt. The hemming machine body is equipped with sewing equipment and a slide groove. A first clamping mechanism and a second clamping mechanism are slidably connected within the slide groove. An auxiliary device and a hemming device are located between the first clamping mechanism and the sewing equipment on the hemming machine body. When the hemming machine performs hemming on curtains, the second clamping mechanism and the first clamping mechanism respectively clamp the first and second ends of the curtain, thereby enabling the curtain to move. Under the action of the first clamping mechanism, the curtain can remain straight, thus preventing wrinkles during movement and resulting in a better hemming effect. Simultaneously, by setting an auxiliary device on the hemming machine body, the curved design effectively mimics finger bending, guiding the hemming of the curtain.
