Description
Technical field
The present invention relates to wiping hydro-entangled non-woven fabric production technology, especially a kind of superfine fibre spun-laced cleaning material and
Its production technology.
Background technology
Currently, the research and development for super-fine fiber material makes much progress.Fineness is usually less than to the fiber of 0.3dtex
Referred to as superfine fibre.The excellent properties that superfine fibre has general fibre incomparable, and have very high surcharge, it is superfine
Single fiber fineness, big specific surface area and abnormal shape fibre section assign the feel of material softness, natural gloss and good
Transparency.Produced numerous " shin-gosen " fabrics based on superfine fibre now, fabric type include woven fabric,
Knitted fabric, non-woven cloth etc., since these " shin-gosen " fabrics contain superfine fibre, make the performance of the fabric original
On the basis of be greatly improved.The mechanical performance of superfine fibre spunlace non-woven material is strong, the smooth soft, elasticity of cloth cover
Good, porosity height, has preferable adsorptivity and filterability, is widely used in advanced Wiping material, high-grade synthetic leather base material, people
Make the fields such as chamois leather.
In the industries such as printing equipment, precision equipment, electromechanics, the shadow to equipment performance such as greasy dirt, dust of equipment surface
Sound is very big, so the general automatic cleaner that is equipped in process of production is used for cleaning.And in automatic cleaner
On the wiper cord that uses mainly cut by Non-woven fabrics and eedle dry goods cleaning wiping cloth.Non-woven fabrics cleaning wiping cloth uses
Natural wood pulp and polyester fiber, which are raw material, to be processed into non-woven fabrics through spun lacing method and forms distinctive wood pulp/polyester double-layer structure, but by
In the distinctive structure of non-woven fabrics, strength is relatively low, in use other than being easier fracture, is also easy to generate fiber
Bits, cause secondary pollution.And eedle dry goods cleaning wiping cloth includes general fibre class and superfine fibre class, wherein superfine fibre class by
In soft, wiping effect is more superior, more welcome by consumer.But when superior fibrillation effect needs long in order to obtain
Between, high concentration alkali decrement, this be easy for the tight ness rating brought reduce greasy dirt easily infiltration and excessively decrement so that cleaning wiping cloth it is excessively soft
It is not suitable as the problems such as wiper cord uses；The especially insufficient space of polyester superfine fibre cleaning wiping cloth sheltered evil people and countenance evil practices, water conservation
Property it is relatively poor, thus unsuitable use as wiper cord.And prolonged alkali decrement treatment, it can be fallen using fiber
The phenomenon of bits.
Low melting point core-skin type polyester complex fiber has cortex and sandwich layer.It is the polyester fibre of low melting point used by cortex
Dimension is conventional polyester fiber used by sandwich layer.Low melting point polyester fiber is in spun lacing drying process, it may occur that melting makes
Do not have the fiber to swim with spunlace non-woven cloth surface, not will produce the phenomenon of bits in wiping process.
Material is identical used in existing Wiping material two sides, cannot meet and be wiped to same equipment different location
When, need the demand using different Wiping materials.
Invention content
It is an object of the present invention to provide a kind of superfine fibre spun-laced cleaning materials, and superfine fibre is enabled to wipe material
Material is not in the appearance dirt space fallen to consider phenomenon to be worth doing, and be capable of providing larger in wiping process.
It is a further object of the present invention to provide a kind of superfine fibre spun-laced cleaning material, two sides has used different materials,
Same Wiping material may make to meet different wiping demands.
It is a further object of the present invention to provide a kind of production technologies of superfine fibre spun-laced cleaning material, enable to produce
It is simple for process, in the case of pollution-free, few weightlessness and low strength loss, produce satisfactory superfine fibre wiping material
Material.Any chemical reagents are used due to not having in this production technology, the strength of non-woven cloth is not just because of a certain fiber group
Part hydrolysis be lost in and reduce, obtained not weaving fabric of superfine fiber has strength high, breathe freely, moisture-inhibiting, adsorption capacity by force, three
Tie up the good characteristics such as the appearance of mixed and disorderly fibre net structure and similar chamois leather.Thus obtained Schizoid superfine fibre spun lacing is non-knits
It makes cloth and is widely used in the fields such as advanced synthetic leather, artificial suede, advanced cleaning wiping cloth.This method is easy to operate, is damaged to fiber
Hinder small, energy expenditure is small, non-environmental-pollution.
In order to solve the above technical problems, the object of the present invention is achieved like this：
A kind of superfine fibre spun-laced cleaning material according to the present invention includes superfine fibre layer, casing play and bottom successively；Institute
