Abstract
The invention discloses a non-woven fabric, which consists of fibrilia with content of more than zero and less than 50wt%, bonding fiber with content of 20 to 40wt%, and other fibers with content of 30 to 70wt% excluding the fibrilia and the bonding fiber. The non-woven fabric of the invention has proper lengthwise and transverse strength on the basis of keeping the unique softness of the non-woven fabrics.
Description
Technical field
The present invention relates to field of nonwoven fabric technology, particularly a kind of nonwoven fabric that contains flax fibre.
Background technology
Nonwoven fabric is the cloth that utilizes adhesive that directive fiber web or mixed and disorderly fiber web bonding are formed.Such as disclosed nonwoven fabric among the BP GB1195233A is exactly that its non-woven fabrics fiber net is immersed in adhesive, thereby the adhesion strength by adhesive realizes bonding between the non-woven fabrics fiber.Development along with technology, the notion extension of nonwoven fabric has obtained expansion, the adhesive that utilizes that it not only is confined to mention in the above-mentioned definition bonds fiber web, and it is expanded to can be to utilize interfibrous frictional force or self bonding force or add the adhesion strength of adhesive or be above-mentioned two or more power, thus the cloth that the fiber web bonding is formed.
At present, Chang Yong non-woven fabrics fiber material comprises natural fabric and chemical fibre; Wherein, described natural fabric comprises cotton fiber and wool fibre, and described chemical fibre comprises low melting point chemical fibre, terylene, polypropylene fibre and viscose etc.; Above-mentioned fibrous material can be staple fibre, long fiber or long filament.
Continuous development along with textile technology, the better sucting wet air permeability that flax fibre has, low static behaviour and good antibacterial characteristics more and more receive publicity, in non-woven fabrics fiber material field, also being extended to from original cotton fiber, wool fibre and chemical fibre uses natural flax fibre to prepare nonwoven fabric, thereby nonwoven fabric has been developed into the bast fiber nonwoven fabric hierarchy of skill, thereby and sought to make the good comprehensive properties nonwoven fabric by the blending of multiple fiber.In the prior art, Chinese patent literature CN1746360A discloses a kind of bast fiber nonwoven fabric, this nonwoven fabric is made up of 50～80% flax fibre and 20～50% low-melting fiber, perhaps fibrous by other of 50～70% flax fibre and 30～50%, perhaps form by 100% flax fibre or 100% fire-retardant flax fibre.This nonwoven fabric uses by the mixing of flax fibre and other fibers, has kept distinctive ventilative, the moisture pick-up properties of flax fibre.Disclosed nonwoven fabric in the document, can select by flax fibre and other fibrous, described other fibers can be cotton fibers, also can be polypropylene fibre, chemical fibre such as terylene or nylon, if in fact select cotton fiber and flax fibre to be mixed with nonwoven fabric, neither there is the frictional force between the fiber preferably between cotton fiber and the flax fibre, there is not available self-adhesion to make a concerted effort yet, more do not add the adhesion strength of adhesive (such as normally used low melting point chemical fibre), so only utilizing cotton fiber and flax fibre is to make powerful high nonwoven fabric, especially the less nonwoven fabric of powerful height and grammes per square metre (generally speaking, the nonwoven fabric grammes per square metre shows that for a short time its quality in unit are is little, so general its thickness is also thinner, so also higher relatively to the requirement of brute force in length and breadth to nonwoven fabric).In addition, described in this patent documentation by flax fibre and all the other the fibrous nonwoven fabric except that cotton fiber because its specific non-woven fabrics fiber component, the flax fibre too high levels, be not suitable for other fiber proportion compatibilities, make its nonwoven fabric for preparing guarantee can't to guarantee simultaneously on the basis of its flexibility to suit in length and breadth to brute force, obviously showing as the nonwoven fabric brute force, low (the applicant once tested by the disclosed technical scheme of this patent documentation, and experimental condition and test data are referring to the contrast test of the embodiment of the present application part.)
Summary of the invention
Problem to be solved by this invention is that flax fibre and other fiber proportion compatibilities are not suitable in the nonwoven fabric of prior art, the nonwoven fabric for preparing can only guarantee its flexibility and can't guarantee simultaneously to suit in length and breadth to the technical problem of brute force, and then provide a kind of and have suitable flax fibre and flexibility is formed, can be had concurrently simultaneously to other fiber compatibilities and in length and breadth to the nonwoven fabric of brute force.
For solving the problems of the technologies described above, greater than zero flax fibre less than 50wt%, content is that the viscose fibre of 20～40wt% and content are that except that flax fibre and viscose fibre other of 30～70wt% are fibrous to nonwoven fabric provided by the invention by content.Preferred described nonwoven fabric is the flax fibre of 20～48wt% by content, and content is that the viscose fibre of 25～35wt% and content are that except that flax fibre and viscose fibre other of 30～50wt% are fibrous.
Wherein, described flax fibre is a tossa.Described other fibers are one or more in cotton fiber, polyster fibre, the viscose.Described viscose fibre is the low melting point chemical fibre; Described low melting point chemical fibre is polypropylene fibre or low-melting-point composite fiber.Wherein, thus described viscose fibre for can at high temperature realize melting the fiber that other fibers are bonded together, this viscose fibre mostly is chemical fibre.
Nonwoven fabric of the present invention is fibrous by flax fibre, viscose fibre and other.Wherein, flax fibre is nonpoisonous and tasteless, good permeability, good hygroscopicity, environmental protection, can uvioresistant and antistatic, but its feel fabric coarse, that make creases easily, drapability is poor, and the flax fibre steel is hard, the cohesive force between the fiber is poor.But in other fibers the cotton fiber comfortable feel its lack flexibility, COLOR FASTNESS is not high and wrinkling easily.Polyster fibre intensity and ABRASION RESISTANCE are good, well-pressed, not yielding and be difficult for fading, but its water imbibition is very poor.Viscose is soft, good luster, good hygroscopicity, good permeability, dyeability are good, and its shortcoming is that wet fastness is poor, promptly meets water intensity step-down.By above-mentioned an amount of flax fibre and an amount of fiber such as cotton fiber, polyster fibre and viscose are bonded together under the effect of viscose fibre, thereby realized the complementation of pluses and minuses between the two kinds or more of fibers, thereby helped the raising of the combination property of bast fiber nonwoven fabric.Wherein, described flax fibre can be linen fibre, tossa, hemp, sisal fiber, kenaf and ramee; Described viscose fibre can be low melting point chemical fibre or compound hot melt fiber, and described compound hot melt fiber comprises core-skin fibre and bi-component meldable fibre again; Described other fibers except that flax fibre and viscose fibre comprise cotton fiber, polyster fibre, viscose, acrylic fiber, nylon fibre, spandex and polyvinyl alcohol fibre etc.
The present invention has advantage as described below:
(1) nonwoven fabric of the present invention is formed by the proper content between flax fibre, viscose fibre and other fibers except that flax fibre, viscose fibre is set wherein, makes that the bast fiber nonwoven fabric that obtains can have flexibility concurrently and in length and breadth to brute force.Show that after tested this nonwoven fabric is when 50 grammes per square metres, its longitudinal fracture intensity is 1493N/m, and cross-breaking strength is 1269N/m, and when 100 grammes per square metres, its longitudinal fracture intensity is 3382N/m, and cross-breaking strength is 2750N/m;
(2) the preferred tossa of the flax fibre in the nonwoven fabric of the present invention, it is lower to select for use tossa to make the cost of nonwoven fabric.
