Description
Technical field
The invention belongs to non-woven material preparation field, particularly relate to a kind of composite wiping material production device and work thereof
Skill.
Background technology
Existing wood pulp composite wiping material apparatus and Technology, substantially employing following two technology:
First method: unclog and readjust into net and add wood pulp paper after spun lacing makes base material again and be combined, through Spunlace line by fine for wood pulp
Dimension is mutually tangled with substrate fiber, makes wood pulp composite wiping material after drying.
Advantage: base material is directly combined with wood pulp paper after spun lacing is reinforced, decreases base material drying, the operation of rolling, improves
Production efficiency, has saved the energy；Wood pulp paper is to produce well, meets production requirement, in process of production, as long as changing
Becoming the quantitative of base material and width, the product produced i.e. may conform to product requirement, and production process is easy to control.
Shortcoming: owing to base material is to unclog and readjust fibrous layer to become base material after spun lacing is reinforced, its grammes per square metre can not be the least, general requirement
More than 25g/m2, adding that the longitudinal and transverse pulling force of fibrous layer is poor, stretch big rate greatly, the grammes per square metre of final products can not be less than 40g/m2, and
And bulk is poor, affect the using effect of finished product.
Second method: the base material coiled material that will make, through unwinding device, puts into abutted equipment and through wet-laying formation
Wood pulp cellulose is fitted, then through Spunlace line, is mutually tangled with substrate fiber by wood pulp cellulose, makes the compound wiping of wood pulp after drying
Wipe material.
Advantage: base material be processed after the reel made, the base material after particularly processing with heat bonding, its weight can be low
In 25g/m2, vertically and horizontally strength and percentage elongation are all significantly better than the base material in first method；Change into using wet method plus wood pulp paper
The method of molding is directly prepared into wet fiber layer and is combined with base material by spun lacing, overcomes finished product pulling force poor, the shortcoming that percentage elongation is big,
Improve product serviceability.
Shortcoming: base material is to put into compounding machine after rolling to be combined with wet fiber layer, needs conversion between rolling up and rolling up, and seriality is raw
Produce cumbersome, and the wastage of material that handoff procedure causes is bigger.Further, since base material first does, basic grammes per square metre is
Being sized, the ratio of product is final grammes per square metre determines when aborning, and its ratio just cannot adjust the most immediately, to product
Change and the optimization of technique bring difficulty.And owing to coiled material will be in order to keep its strength character, therefore its grammes per square metre can not mistake
Low, 18g/m to be reached2, it is impossible to meet the requirement of low grammes per square metre Wiping material.
Summary of the invention
The composite wiping material bulk that it is an object of the invention to solve to produce in prior art is poor, and grammes per square metre is higher, vertical
Lateral pull difference is big, the problem of the problems such as percentage elongation is big, and provides a kind of composite wiping material production device, to realize two kinds not
Fibrous layer prepared online by same fiber, can adjust the proportioning of two kinds of fibers at any time, improves quality of finished.
The present invention realizes particular by techniques below scheme:
