Manufacturing method and application of ptt false eyelashes

Abstract

A manufacturing method of PTT false eyelashes is provided, including material preparation: preparing an eyelash stalk and an eyelash filament, the eyelash stalk and eyelash filaments are made of PTT material; fixation step: fixing the eyelash stalk and eyelash filament on a fixed plane according to a preset warpage degree; heating step: heating the fixed eyelash stalk and the fixed eyelash filament by a heating device; shape fixation: setting the heating temperature and heating time of the heating device, observing changes of a warpage degree and a bulkiness of the PTT false eyelashes, if the warpage degree and the bulkiness do not reach preset values, increasing the heating time until the warpage degree and the bulkiness is reached to the preset values.

What is claimed is: 
     
         1 . A manufacturing method of PTT false eyelashes, comprising material preparation: preparing an eyelash stalk and an eyelash filament, the eyelash stalk and eyelash filaments are made of PTT material;
 fixation step: fixing the eyelash stalk and eyelash filament on a fixed plane according to a preset warpage degree;   heating step: heating the fixed eyelash stalk and the fixed eyelash filament by a heating device;   shape fixation: setting the heating temperature and heating time of the heating device, observing changes of a warpage degree and a bulkiness of the PTT false eyelashes, if the warpage degree and the bulkiness do not reach preset values, increasing the heating time until the warpage degree and the bulkiness is reached to the preset values.   
     
     
         2 . The manufacturing method according to  claim 1 , wherein before the fixation step, it further comprises a placement step, and the placement step is specifically: placing several pairs of false eyelashes with the preset warpage degree on the fixed plane at intervals of 0.5-2 cm for each pair, and pre-fixeding by fixing glue. 
     
     
         3 . The manufacturing method according to  claim 1 , further comprising: a preheating step, the preheating step is before the heating step, the preheating step is setting the heating temperature of the heating device to a predetermined value, preheating continuously for a period of time, wherein the preheating step is configured to match a suitable preheating temperature according to a density of the false eyelashes to be heated and a thickness of the eyelash filaments. 
     
     
         4 . The manufacturing method according to  claim 1 , wherein the heating step is an overall heating mode, and the overall heating mode is specifically: placing the fixed eyelash stalk and the fixed eyelash filament as a whole into the heating device to heat. 
     
     
         5 . The manufacturing method according to  claim 4 , wherein the heating step is a single-sided heating mode, and the single-sided heating mode is specifically that the heating device is provided with a heating surface, heating the false eyelashes through the heating surface by the heating device. 
     
     
         6 . The manufacturing method according to  claim 1 , wherein in the heating step, the heating temperature generated by the heating device is 40 to 210° C. 
     
     
         7 . The manufacturing method according to  claim 1 , wherein the warpage degree is divided into a bottom warpage degree and a top warpage degree, the bottom warpage degree is 15 to 30°, and the top warpage degree is 45 to 90°. 
     
     
         8 . The manufacturing method of  claim 1 , wherein the bulkiness distance between the bottom layer and the top layer of the eyelash filament is 3-15 mm. 
     
     
         9 . The manufacturing method according to  claim 1 , further comprising a packing, wherein the packing is putting the false eyelashes into a box after shape fixation. 
     
     
         10 . An application of the PTT false eyelashes manufactured by the manufacturing method of  claim 1 .
