The lock ring interface that described surface fibre layer is done net at polyester has the fiber hair network interface.

The dried net of described polyester, the positive flocking of doing net at polyester form single face has end or the dried net of flocking for no reason; The positive and negative flocking simultaneously of doing net at polyester forms the dried net of two-sided flocking for no reason.

Beneficial effect; Owing to adopted such scheme; The surface of adopting needling process the fibrage of different fineness and grammes per square metre to be thrust the dried stratum reticulare of polyester; Fiber uses synthesising fibre; Like polyamide fibre and terylene; Perhaps use the mixture of wool and synthesising fibre; Mixed proportion is 10% to 50%; The mixed proportion of fiber; Fineness and grammes per square metre can be according to the paper kinds of producing; The speed of a motor vehicle; Air permeability requires different with the use position and changes; Needled flocking can be single face (flocking of paster face); Also can be two-sided; General single face flocking has been applied to the dried net of end flocking; Fibrage fleece interface adopts the form of otch section overlap joint, and fibrolaminar laying can effectively be eliminated page and directly contact rugged " wire mark " that produces with dried net; Polyester is done line footpath, the number of plies and the institutional framework of net and can be confirmed according to the variation of the required air permeability of different paper machine application sites production different papers; Dried stratum reticulare can provide the paper page drying position process suitable air permeability; The dried net of polyester can be for no reason; Also end can be arranged; There is the dried Netcom of end flocking to cross connecting ring and is connected, have the dried net of end flocking to provide convenient for installing with connecting pin.

The dried net of this flocking is divided into dried stratum reticulare and fibrage; Manufacturing process has merged papermaking wire-cloth and two production technologies of felt; Have higher permeability, also can effectively eliminate paper " wire mark " simultaneously, thereby reach the effect that improves the paper machine speed of service and page presentation quality simultaneously.Solve the papermaking of the dried net of polyester and caused the overweight and low excessively problem of dryer felt papermaking air permeability of paper " wire mark ", reached the purpose of the utility model.

Advantage: the dried net of this flocking both can reach the smoothness of the fine and smooth paper surface that brings of dryer felt surfacing; Eliminated " wire mark "; Can reach polyester again does the higher air permeability of net and effect is installed easily; The lock ring interface provides mounting condition easily, has shortened the set-up time, has improved paper machine speed and has produced paper quality.

The dried net of flocking is novel dried the fabric that the advantage collection of dried net of polyester and dryer felt is given the whole body; Not only has higher air permeability but also have the characteristics of effective elimination paper " wire mark "; Simultaneously mounting structure condition easily is provided also, thereby has reached the drying efficiency that improves paper machine effectively and the effect of page surface quality.
