Description
Technical field
The utility model relates to a kind of papermaking dryer felt, particularly a kind of aging-resistant flocking papermaking dryer felt.
Background technology
In the production process of paper; Though common BOB dryer felt and BOM composite felt have the advantage of the more smooth exquisiteness of blanket face, the generation of no wire mark; But owing to receive the restriction of structure; Still have that density is excessive, thickness is excessive, size distortion is excessive, air permeability is extremely low, be prone to shortcomings such as aging, cause easily that paper page drying position is inhomogeneous, rate of drying is low excessively, be prone to assemble steam in the blanket, page is prone to the paper defects that produces in " seersucker " dry runs such as " sweat stain ", and the steam use amount is very big.Though the woven dried net of conventional polyester has the high advantage of air permeability; But the dried wire mark that paper occurs is to deal with problems; Even adopt the dried net of polyester flat filament still can not thoroughly deal with problems, this is that particularly property paper kind institute is unallowable for high-grade paper kind.
The flocking dryer felt is divided into polyester spiral flocking dryer felt and the woven flocking dryer felt of polyester from structure; Be divided into for no reason and end flocking dryer felt is arranged from type; From the hair state of shop, be divided into single face shop hair and two-sided shop hair flocking dryer felt again, have abutted seam type flocking dryer felt representing the high-end product of flocking dryer felt because of characteristics such as joint treatment technology content are high, be convenient to install.
The utility model content
The purpose of the utility model is to provide a kind of: smoothness is good, felt mark is light, a kind of aging-resistant flocking papermaking dryer felt of high temperature resistant, long service life.
The purpose of the utility model is achieved in that this papermaking dryer felt comprises surperficial dried stratum reticulare, median fiber layer and dried stratum reticulare, and median fiber layer and dried stratum reticulare link together, and surperficial dried stratum reticulare is connected the outside of median fiber layer and dried stratum reticulare.
Described surface fiber layer is paster face fibrage and bottom surface fibrage.
Described dried stratum reticulare comprises dried stratum reticulare of spiral or woven dried stratum reticulare; On dried stratum reticulare, implant short fiber is arranged.
The dried stratum reticulare of described spiral is the helical tissue structure, and what spiral layers adopted is that diameter is 0.7 mm high temperature resistance polyester fiber, and what connect two helical structures is that diameter is 0.9 mm high temperature resistance polyester fiber.
Described woven dried stratum reticulare is double-layered structure's structure, and top line is the high temperature resistant PET of 0.5 mm, and lower layer warp yarns is 0.7 mm high temperature resistance polyester fiber, and weft yarn is 0.4 mm high temperature resistance polyester fiber, forms according to once warp rib's structure is woven on two.
The laying of described paster face fibrage, median fiber layer, bottom fiber layer is that front by dryer felt is to reverse side overstriking gradually.
Beneficial effect is owing to adopted such scheme, anti-aging flocking dryer felt, its structure to comprise paster face fibrage, median fiber layer, dried stratum reticulare (and bottom surface fibrage); Characteristics such as wherein dried stratum reticulare adopts a kind of helical structure to do net or the dried net of a kind of machine-knitted structure, has good stability, and smoothness is high, and intensity is big; Dried stratum reticulare in the front or positive and negative implant PET, PPS, the high temperature resistant short fiber of Nomax simultaneously, have thorough elimination wire mark, air permeability is good, brute force is big, be difficult for falling characteristics such as hair, wear-resistant, anti-aging, long service life.Comprise: for no reason the flocking dryer felt with the big series of abutted seam type flocking dryer felt two is arranged.Can make fibrage and dried stratum reticulare strong bonded through acupuncture and high-temperature shaping technology; Strengthen cohesive force, make the blanket face that better deflection and planarization, dimensionally stable arranged; Reduce longitudinal tensile strain and cross-direction shrinkage; Avoid a mao phenomenon, smoothness, the felt mark that effectively improves page is light, anti-aging, the service life of prolongation dryer felt, has reached the purpose of the utility model.
Advantage: this flocking dryer felt comprises the dried net of flocking for no reason and has the flocking of abutted seam type to do net two big series, can be applicable to dryer temperature 110-150 ℃, the flocking dryer felt of the various use dryer felt paper machines of speed of a motor vehicle 200-1000 m/min.Produce high-grade facing paper, cultural paper, coated white cardboard, wrapping paper, transfer printing paper.Have thorough elimination wire mark, air permeability is good, brute force is big, be difficult for falling the characteristics of hair, wear-resistant, anti-aging, long service life.
