Abstract
The invention relates to a non-woven fabric for moisture absorption, which comprises a plurality of long fibers with the length ranging from 10mm to 76mm, a plurality of composite short fibers with the length ranging from 1mm to 10mm and hot melt adhesion, and a plurality of cellulose fibers, wherein the fibers are substantially intertwined with one another. The invention can reduce the raw material cost of the prior non-woven fabric for moisture absorption and improve the mechanical properties (such as tensile strength and elongation) and absorptivity thereof by using the composite short fiber with hot melt adhesion and the cellulose fiber.
Description
Technical field
The present invention relates to a kind of moisture absorption Nonwovens, particularly relate to a kind of moisture absorption Nonwovens that comprises long fiber, staple fibre and cellulose fibre.
Background technology
Paper handkerchief is the essential articles for use of daily life, is used for the spot of wiping removing objects surface attachment.General paper handkerchief can be divided into dry paper handkerchief and hygenic towelette, no matter but be that dry paper handkerchief or hygenic towelette all need to meet flexibility, tensile strength (tensile strength), absorptivity and surface and need the characteristics such as level and smooth submissive.
Paper handkerchief is in the past mostly that two layer web is formed through water thorn (water-jet) method.The long fiber that this fiber web is is 10mm to 76mm by many average length scopes is processed and is formed through combing (carding), and this long fiber is chemical fibre.So, this paper handkerchief is prepared with chemical fibre completely, because chemical fibre cost is high, can cause prepared paper handkerchief cost of material high, does not meet dealer's cost benefit.
TW182129 patent announcement case discloses a kind of high tenacity wet paper handkerchief.This high tenacity wet paper handkerchief comprises two cleaning layers, and is folded in the moisture absorption layer between those cleaning layers.Those cleaning layers and moisture absorption layer utilize hot rolling method to carry out combination.The kapok seeds fiber that those cleaning layers are is respectively 1.25mm to 5mm by length range is formed, and this moisture absorption layer is that the rayon of 50wt% (rayon) artificial cellucotton is mixed with the polypropylene fibre of 50wt% and formed via hot blast method.So, rayon (rayon) the artificial cellucotton cost that this moisture absorption layer uses is high, and the prepared high tenacity wet paper handkerchief of use hot blast method can be flat and harder.
Because above-mentioned, a kind of more soft and paper handkerchief that cost is low is provided, be the problem that this technical field person skilled can break through again.
Summary of the invention
The first object of the present invention is to provide that a kind of cost is low, engineering properties (as tensile strength and percentage elongation) is good, and the good moisture absorption Nonwovens of absorptivity.
The second object of the present invention is to provide the preparation method of a kind of moisture absorption Nonwovens.
The object of the invention to solve the technical problems realizes by the following technical solutions.Moisture absorption Nonwovens of the present invention, comprises:
Many the long fibers that length range is 10mm to 76mm;
Many the composite short fibers with hot melt tackness that length range is 1mm to 10mm; And
Many cellulose fibres, those fiber essence are entangled with mutually.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Preferably, aforesaid moisture absorption Nonwovens, wherein this long stapled material comprises the group that at least one following material forms: polyethylene, polypropylene, polyethylene terephthalate, rayon, and cotton fiber.
Preferably, aforesaid moisture absorption Nonwovens, wherein this composite short fiber with hot melt tackness be selected from polyethylene-polypropylene fiber, polyethylene-dacron fibre, low temperature PLA-high temperature acid fiber by polylactic, through the polyethylene-polypropylene fiber of maleic anhydride upgrading, through the polyethylene-dacron fibre of maleic anhydride upgrading, or their combination.
Preferably, aforesaid moisture absorption Nonwovens, wherein taking this moisture absorption by the total amount of Nonwovens as 100wt%, the use amount summation scope of those cellulose fibres is 5wt% to 60wt%.
Preferably, aforesaid moisture absorption Nonwovens, wherein taking this moisture absorption by the total amount of Nonwovens as 100wt%, described in there is the composite short fiber of hot melt tackness use amount summation scope be 1wt% to 20wt%.
Preferably, aforesaid moisture absorption Nonwovens, wherein the length range of this cellulose fibre is 1mm to 5mm.
The object of the invention to solve the technical problems realizes by the following technical solutions.The preparation method of Nonwovens for moisture absorption of the present invention, comprises following steps:
(a) provide blended fiber, comprising many length ranges is the composite short fiber with hot melt tackness and many cellulose fibres of 1mm to 10mm;
(b) this blended fiber is carried out to air lay processing and heat treatment, form blended fiber cloth;
(c) provide two long fibre net, the long stapled mixture that those long fibre net are is 10mm to 76mm by many length ranges is processed and is formed via combing;
(d) this blended fiber is arranged between those long fibre net, and carries out water thorn and process, can obtain moisture absorption Nonwovens.
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Preferably, the preparation method of Nonwovens for aforesaid moisture absorption, wherein taking this moisture absorption by the total amount of Nonwovens as 100wt%, the use amount summation scope of described cellulose fibre is 5wt% to 60wt%.
Preferably, the preparation method of Nonwovens for aforesaid moisture absorption, wherein taking this moisture absorption by the total amount of Nonwovens as 100wt%, described long stapled use amount summation scope is 10wt% to 80wt%.
By technique scheme, beneficial effect of the present invention is: compared to the paper handkerchief Nonwovens that only used long fiber to make in the past, the present invention has composite short fiber and the cellulose fibre of hot melt tackness by use, replace part long fiber, the cost of material of the Nonwovens of moisture absorption in the past can be reduced, and its engineering properties (as tensile strength and percentage elongation) and absorptivity can be promoted; And method for making of the present invention can make moisture absorption Nonwovens in conjunction with air lay processing, heat treatment, combing processing and the processing of water thorn in a production line.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
