Stuffing and manufacturing method thereof

Abstract

Disclosed are a stuffing ( 4 ) and a method for manufacturing the same, the stuffing ( 4 ) comprising a branch ( 402 ) and trunk ( 401 ) structure formed with a microporous polymer, and having a trunk ( 401 ), and branches ( 402 ) formed by splitting from the trunk ( 401 ). The stuffing ( 4 ) of the present invention can still maintain at a dispersedly stuffing state after multiple washings, without notable phenomena such as agglomeration and entanglement.

1 . A stuffing, characterized in that the stuffing comprises a branch and trunk structure formed by a microporous polymer, wherein the branch and trunk structure comprises a trunk and branches formed by splitting from the trunk, and wherein the branch and trunk structure has a maximum longitudinal length of about 10 to about 130 mm on average and a maximum lateral dimension of about 2 to about 15 mm on average. 
     
     
         2 . The stuffing of  claim 1 , characterized in that the trunk has an average lateral dimension of about 1 to about 10 mm. 
     
     
         3 . The stuffing of  claim 1 , characterized in that the branches have an average lateral dimension of about 0.5 to about 5 mm. 
     
     
         4 . The stuffing of  claim 1 , characterized in that the trunk length is equal to or less than the longitudinal length of the branch and trunk structure. 
     
     
         5 . The stuffing of  claim 1 , characterized in that the branches have an average length between about 1 and about 6 mm. 
     
     
         6 . The stuffing of  claim 1 , characterized in that the branches are formed by laterally splitting along a longitudinal length direction of the trunk at an interval of about 1 to about 6 mm on average. 
     
     
         7 . The stuffing of  claim 1 , characterized in that the branches are formed by splitting at one end of the trunk. 
     
     
         8 . The stuffing of  claim 1 , characterized in that the branch and trunk structure has a planar two-dimensional structure. 
     
     
         9 . The stuffing of  claim 8 , characterized in that the branch and trunk structure has an average thickness of about 0.25 to about 2 mm. 
     
     
         10 . The stuffing of  claim 1 , characterized in that the microporous polymer is selected from thermal insulating materials. 
     
     
         11 . The stuffing of  claim 10 , characterized in that the thermal insulating materials are expanded plastics. 
     
     
         12 . The stuffing of  claim 11 , characterized in that the expanded plastics include expanded materials produced from one of the following materials: polyethylene, polyvinyl chloride, polystyrene or polyurethane. 
     
     
         13 . The stuffing of  claim 1 , characterized in that the stuffing has water-wash resistance. 
     
     
         14 . A method for manufacturing a stuffing, including providing a microporous polymer sheet having a thickness of about 0.25 to about 2 mm, allowing the sheet to be positioned between two gear blade-bearing roller wheels rotating in reverse directions for cutting, and adjusting a gap between the two gear blade-bearing roller wheels to between 0 and about 1 mm so as to cut and mold the sheet into a branch and trunk structure. 
     
     
         15 . The method of  claim 14 , characterized in that the gear blade-bearing roller wheels have blades arranged at an interval and spirally distributed along an axial line thereof. 
     
     
         16 . The method of  claim 14 , characterized in that the gear blade-bearing roller wheels have a linear velocity of about 100 to about 300 mm/s.
