The content of the melt viscosity substance is 2~5g/m2。
The meltblown fibers be polyolefine fiber, polyester fiber, Fypro, polyurethane fiber, acid fiber by polylactic or
Their mixture.
The percentage that the weight of the wood pulp cellulose net accounts for the cloth for cleaning total weight is greater than 50%.
The percentage that the weight of the wood pulp cellulose net accounts for the cloth for cleaning total weight is 65%~80%.
A kind of manufacturing method of cloth for cleaning, including the following steps:
(1) wood pulp is broken up by plucker roller shredding, passes through jet pipe under the action of secondary air with after melt viscosity material mixing
Form the wood pulp cellulose net containing melt viscosity substance;
(2) meltblown technique is used, thermoplastic resin is heated, melts, will be sprayed from spinneret using high temperature, velocity heated gas
The solution thread of thermoplastic resin out dispels into the fibre bundle of fibre diameter≤10 μm, so that it is fine to form melt-blown with thermal current
Net is tieed up, and is intersected with two lateral positions of the wood pulp cellulose net containing melt viscosity substance, forming two sides is meltblown fiber web,
Centre is the multiple structural fibre net of the wood pulp cellulose net containing melt viscosity substance;
(3) web is consolidated by the multi-layered web by heating device, and forming upper and lower two layers is meltblown fibers
Net, middle layer are the cloth for cleaning of the wood pulp cellulose net containing melt viscosity substance.
The melt viscosity substance is low melting point polyester fiber, ES staple fiber, two-component spunbond long fibre or theirs is mixed
Close object.
The heating device is that hot-air oven, hot roll or both combine.
After adopting the above technical scheme, cloth for cleaning of the invention can be made using cloth for cleaning manufacturing method of the invention, by
In the wood pulp cellulose net of the middle layer of cloth for cleaning of the invention contain melt viscosity substance, in the fabrication process, formation it is more
