Abstract
Even if the present invention provides contacts the also few hydrophiling non-woven fabrics with durability of hydrophilic deterioration with water repeatedly.So that non-woven fabrics is contained alkenyl succinic acid, alkenyl succinic anhydride, alkylene dicarboxylic acids, alkenylene dicarboxylic acids or their mixture and constitutes hydrophiling non-woven fabrics as amphiphilic species.
Description
Technical field
The present invention relates to hydrophiling non-woven fabrics.More particularly, it relates to the hydrophiling of the durability persistently shown with hydrophily
Non-woven fabrics.
Background technique
The non-woven fabrics formed by synthetic fibers is opened from the surfacing of cleansing tissue, hygenic towelette, amenities (paper diaper etc.)
Begin the multiple fields transition to daily necessities and uses.For example, it is preferable to using the non-woven fabrics formed by polyolefin series fiber, this be because
It is excellent for mechanical property and chemical resistance etc..
However, synthetic fibers as polyolefin series fiber be substantially it is hydrophobic, and using the cotton as natural fiber
Flower, wood pulp compare as the staple fibre of raw material, repel water, and it is poor to hydrophilies such as the wetabilitys of water to lack.
Therefore, show the non-woven fabrics (hydrophobic nonwoven) being made of hydrophobic fibres such as polyolefin series fibers hydrophilic
The method of property, proposes various methods.For example, as described below.
(1) make the attachment of the surface of fiber or non-woven fabrics with the hydrophilic agent of surfactant typical example.
(2) it constitutes to be kneaded in the thermoplastic resin of fiber surface and has hydrophilic agent.
(3) by Corona discharge Treatment, Low Temperature Plasma Treating, ozone treatment, UV treatment etc. to fiber surface
Import hydrophilic functional group.
(4) handled by fluorine processing, graft polymerization processing, using the sulfonation that oleum, anhydrous slufuric acid gas carry out etc.,
Hydrophilic functional group is imported to fiber surface.
Herein, the method for (1) is easy and cheap method, thus by the non-woven fabrics of hydrophiling with water first contacts
In the case of, it can penetrate or absorb water.That is, initial hydrophilicity is sufficient.
But the non-woven fabrics is with water when contacting, surfactant is also flowed out with water etc. together, and hydrophily greatly drops
It is low.That is, it is such to have the shortcomings that the hydrophily after contacting repeatedly with water (durable hydrophilic) reduces.
In addition, the method by (2)~(4) has high durable hydrophilic by the non-woven fabrics of hydrophiling.
But the method for (2)~(4) have the following disadvantages: manufacturing equipment becomes extensive, treatment process complicates, into
And it manufactures funds and gets higher.
In addition, the method as the durable hydrophilic for improving hydrophobic nonwoven, proposes a variety of pairs of non-woven fabrics or structure
Apply the scheme of various hydrophilic agents at the fiber surface of non-woven fabrics.
The hydrophilic agent containing polyoxy alkylidene modified organic silicon is proposed in patent document 1.It is proposed in patent document 2
Hydrophilic agent containing alkylol amide type compound and polyoxy alkylidene modified organic silicon.It is proposed in patent document 3 containing poly-
The hydrophilic agent of fatty acid glyceride.
But there are the following problems: even with these hydrophilic agents, the hydrophily after keeping is also easy drop for a long time
It is low, it is hydrophilic when being taken care of for a long time especially in warehouse for easily becoming high-temperature high-humidity etc. to reduce significantly.
In patent document 4, the hydrophiling non-woven fabrics high as durable hydrophilic is proposed at fiber surface sericin
The non-woven fabrics managed.
But dissolved easily in water if being kept intact due to sericin, so sometimes for carry out crosslinking Treatment and/
Or water-soluble base processing etc..In crosslinking Treatment, due to not only needing to be coated with sericin, it is also necessary to react sericin
Process, so operation becomes complicated.On the other hand, in water-soluble base processing, sericin is weakened by insoluble matrix, just
The case where hydrophily of phase dies down.
It is proposed in patent document 5,6 in addition to comprising polyether polyester block copolymer (A ingredient) and polyether polyols
Senior alkyl ether (B component) except, also include alkenyl succinate acid metal salt (C ingredient) hydrophilic agent.A ingredient and B component
For assigning good hydrophily, C ingredient is to improve the combing weaved under speed when manufacture combing formula non-woven fabrics in high speed
What passability was compounded.In addition, C ingredient is soluble easily in water and is difficult to helpful to hydrophilic durableization.
