Technical field
The present invention relates to textile technology field more particularly to a kind of non-woven cloths that oleophylic is hydrophilic.
Background technology
Spunlace non-woven technique is referred to as spunlaced or hydroentanglement processes.Spunlace non-woven technique is to pass through high pressure
Flow continuously sprays fibre web, make under hydraulic action fiber movement in fibre web, displacement and rearrange and mutually tangle,
So that fibre web is reinforced and obtains certain physical mechanical property.
In the U.S., popular industrial wipe is usually to pass through spun lacing with wood pulp cellulose with PP spunbonded nonwovens
Method is combined with each other and manufactured cloth.It is long that shorter wood pulp cellulose can uniformly and intimately be become entangled in spunbond by water jet process
Around silk, so that it had not only been had intensity but also have absorbability.
But in wood pulp spunlace non-woven cloth series of products, there are problems that one is difficult to avoid that, i.e. spunlace non-woven cloth
" falling bits " problem.Since wood pulp length is too short, under the injection repeatedly of high-pressure jet, especially staple fiber is driving in flow
Fibre web is easily left down, generates certain turnover rate, generally 10% or more, this makes fibrous raw material cost greatly increase.And it is lost in
Wood pulp fluff dimension may enter the water circulation system of spun-laced machine, be easy to block hole for water spraying, and then influence product quality.
It is a kind of important method in nonwovens process that fibre web is reinforced in heat bonding, mainly utilizes thermoplastic polyester
Material can soften melting after being heated to certain temperature, can cure this feature after cooling, make the short fine heated rear few fibers of hot melt
Soften melting, adhesion is generated between fiber, and the wood pulp fluff by uniform spreading in lower section is wrapped up wherein, fibre web is able to after cooling
It reinforces and becomes non-woven fabrics.Such mode avoids " falling bits " of non-woven fabrics, and less energy consumption, simple for process.
The cleaning wiping cloth of most domestic be all made of spun lacing processing form, but with regard to spunlace non-woven cleaning wiping cloth and

Cleaning wiping cloth has good water imbibition and flexibility generally using viscose rayon, cotton fiber, terylene as primary raw material.According to grinding
Study carefully, the water absorption of spunlace non-woven cleaning wiping cloth can reach 10 times of own wt or more.But spunlace non-woven cleaning wiping cloth is for life
The removal of finish is just slightly aobvious inferior in work.
Cellulose fibre is also known as staple fibre, includes mainly viscose rayon, acetate fiber, copper ammonia fiber etc., is to utilize
The natural materials such as cotton linter, timber, bamboo, bagasse, reed, by certain technique processing method to its cellulosic molecule weight
It moulds and obtains.
Cellulose fibre is a kind of fiber that water imbibition is extremely strong, and the hydrophily of material is improved often as hydrophilic base material.Example
It is defended in material Ru medical, using viscose rayon and blend polyester, spun lacing is reinforced, and water absorption rate can reach 5-6 times.But cellulose fibre
Production technology it is complicated, need by pulp after highly basic dissolves, after experienced, sulfonation, dissolving, filtering, deaeration, maturation, then
Spinning can just obtain cellulose fibre.It consumes energy, and big, environmental contamination is strong, and gained cellulose fluff price is high.
In field of textiles, melt-blown is called for short " M " since it is English for " Meltblowing ", while spunbond（Also known as
" spinning molten "）It is called for short " S " because its English is " Spunbond ".In field of textiles, " SM " is used to indicate that spunbond is meltblown compound
Non-woven fabrics uses " M " to indicate melt spraying non-woven fabrics, this is analogized.In field of textiles, PP refers to polypropylene, also known as polypropylene fibre.
Currently, can not avoid the spunbond pulp non-woven cloth of the pollution and waste in cellulose fibre production process.
