Description

Technical Field

[0001] The present invention belongs to the technical field of beauty and cosmetics, and particularly relates to a processing technology for spraying non - adhesive thermoplastic false eyelashes. Background Art

[0002] False eyelashes are artificial eyelashes used to beautify the eyes. Generally, by lengthening and thickening the eyelashes, the eyes look bigger, brighter, plumper and more expressive. False eyelashes have a long history, and records of false eyelashes can be found in ancient Egyptian and Roman literature as early as 2000 BC. The materials for making false eyelashes include plastics, cotton, feathers, etc. And with the use of false eyelashes made of different materials, the effects shown (such as exaggerated stage effects) are also different.

[0003] Existing eyelash stalk lines are generally composed of cotton threads, fish silk threads, nylon threads and various resin - based glues. Now the traditional eyelash stalk line is two lines, divided into a front line and a back line. Between the front line and the back line are multiple clusters of eyelashes composed of various hairs, and then glue is irrigated between the front line and the back line for adhesion to achieve the fixing effect. In addition to the function of fixing the eyelashes, the eyelash stalk line is also the part that directly contacts the human skin. In the prior art, two lines are used to bond multiple eyelashes located therebetween with glue. The eyelash stalk formed in this way is relatively thick and heavy. When wearing, the wearer is more likely to have a foreign body sensation and it affects the beauty. In addition, this kind of glue - coated eyelash stalk line will become hard and easy to break after being stored for too long (more than 6 months) and is not suitable for wearing. Finally, the existing manufacturing process of the glue - coated eyelash stalk part is complex and cumbersome, and the drying time after applying glue is at least 6 - 24 hours. Summary of the Invention

[0004] Object of the Invention: The present invention makes improvements to the problems existing in the above - mentioned prior art, that is, the present invention discloses a processing technology for spraying non - adhesive thermoplastic false eyelashes.

[0005] Technical Solution: A processing technology for spraying non - adhesive thermoplastic false eyelashes comprises the following steps:

[0006] (1) Produce a hot - sprayed eyelash silk roll;

[0007] After the eyelash silk pulled out by a hot - extrusion wire machine is arranged in a straight line, it is first subjected to the first cooling treatment, and then passed through a closed - type hot - spraying device. The eyelash silk arranged in a straight line is hot - sprayed through a high - pressure multi - nozzle, and after the spraying is completed, it is subjected to the second cooling treatment, and then wound into a hot - sprayed eyelash silk coil by a wire coiling machine;

[0008] (2) Produce hot - sprayed eyelash filaments;

[0009] Cut, segment and sharpen the hot - sprayed eyelash silk coil obtained in step (1) to make a bundle of hot - sprayed eyelash filaments with a height of 5 cm.

[0010] (3) Manufacture a thermally sprayed eyelash filament sheet;
