Description
Technical field
The invention belongs to facial mask manufacturing technology fields, and in particular to a kind of manufacturing method of the ultra-fine facial mask cloth of multicomponent.
Background technique
It is a kind of common spinning manufacturing technology that polymer melting, which is spun to cloth technology, and spun-bond process nonwovens process is polymerization
Object squeezes a kind of technology of networking manufacture non-woven material, it carries out melt spinning networking, fibre web warp using the melt of high polymer
Machinery, chemically and thermally non-woven cloth is made after reinforcing in bonding etc..Spun-bonded non-woven forms fibre web by continuous filaments at random, tool
There is good physical mechanical property；Thus manufactured continuity long filament cloth strength is high, at low cost, but cloth cover is coarse, feel is stiffening,
It does not absorb water.
Skin care item facial mask cloth on the market is substantially using a kind of or three kinds of fibers prepared by shredding, comb
Reason, networking reinforce using mechanical, chemistry or heat bonding and form staple fiber facial mask cloth, and facial mask elasticity, hand is thus made to obtain
Feel, use comfort and docile property it is poor.
Summary of the invention
The purpose of the present invention is to provide the manufacturing methods of the ultra-fine facial mask cloth of a kind of multicomponent (1) to cut PA-6 polymer
Piece, pet polymer slice and PLA polymer chips carry out crystallizing and drying, melt extruded, the obtained melting of pre-filtering respectively
Body, respectively by metering vessel metering, proportionally vasopressing injection passes through certain temperature and humidity cooling wind into multi-component spun wire hole
The compound spun filament of multicomponent is obtained under state；(2) spun filament is subjected to narrow body formula air drawing spinning, then will be above made
The combination of multiple groups type fibers by air-flow or mechanical means, be paved into continuity web；Again by this continuity web benefit
Dispersed with high pressure water flow, PA-6, PET and PLA conjugate fiber silk division under high pressure water flow effect in fibre assemblies
It opens, forms the continuous PA-6 superfine fibre silk of high-elastic character and PET superfine fibre long filament；It is high while the division of high pressure water needle
Variety classes high polymer, PA-6 superfine fibre silk, PET superfine fibre silk and the PLA superfine fibre silk of independence are rushed embedding by hydraulic pressure
The filament ultrafine fiber cloth of 3 D stereo shape structure is formed on to roller；The roller is divided into tow sides, and front is rule
Solid netted or decorative pattern roller, reverse side is the steel surface of small pore；Again by this long filament ultrafine non-woven fabric, drying
Afterwards, it is sufficiently submerged in high-temperature water to carry out washing heat treatment, in some tension, conjugate fiber is sufficiently divided, and then will
The ultra-fine facial mask cloth of high resiliency multicomponent can be obtained further in non-woven fabrics sizing, in the filament ultrafine fiber cloth
There are different size of pore between PA-6, PET and PLA superfine fibre, these pores increase the ultra-fine cloth elasticity of long filament
And drapability, make cloth cover while meeting super soft plentiful, has good Degradable environment protection.Further, the step
In rapid 2, multicomponent composite filament handle under conditions of high-temperature water, makes season crack between component fibre；It is not necessarily to
Other any chemical treatments.
Further, the superfine fibre cloth of the 3 D stereo bicomponent filament yarn shape structure has 3 D stereo reticular structure,
Different size of capillary cavity is formed between continuous filaments multicomponent superfine fibre silk.
The beneficial effects of the present invention are: different size of capillary chamber is formed between continuous filaments multicomponent superfine fibre silk
Body, so that cloth cover produces more capillary gaps, so that cloth surface is more plentiful, band liquid measure is significantly increased, and can sufficiently be increased
The uptake of Essence, it is super flexible to realize the high resiliency of ultra-fine facial mask cloth, meanwhile, fiber while abundant cracking is opened,
Fiber passes through the soft processing of secondary water, causes cloth cover finer and smoother, and patch skin is good.At the same time, since the introduction of PLA is so that ultra-fine
Fiber facial mask cloth has degradability, more environmentally friendly.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
A kind of manufacturing method of the ultra-fine facial mask cloth of multicomponent comprises the steps of: that (1) gathers PA-6 polymer chips, PET
It closes object slice and PLA polymer chips carries out crystallizing and drying, melt extruded, the obtained molten mass of pre-filtering respectively, pass through respectively
The metering of metering vessel is crossed, proportionally vasopressing injection is into multi-component spun wire hole, by obtaining under certain temperature and humidity cooling wind state
To the compound spun filament of multicomponent；(2) spun filament is subjected to narrow body formula air drawing spinning, then will the above made multicomponent
Fiber type combination is paved into continuity web by air-flow or mechanical means；This continuity web is utilized into high pressure water again
Stream is dispersed, and PA-6, PET and PLA conjugate fiber silk under high pressure water flow effect in fibre assemblies are split off, and is formed high
The continuous PA-6 superfine fibre silk of elastic shape and PET superfine fibre long filament；While the division of high pressure water needle, high hydraulic pressure will not
With type high polymer, PA-6 superfine fibre silk, PET superfine fibre silk and the punching of PLA superfine fibre silk of independence are embedded on roller
Form the filament ultrafine fiber cloth of 3 D stereo shape structure；The roller is divided into tow sides, and front is regular stereoscopic graticule
The roller of shape or decorative pattern, reverse side are the steel surfaces of small pore；Again by this long filament ultrafine non-woven fabric, after drying, sufficiently soak
Enter to high-temperature water and carry out washing heat treatment, in some tension, conjugate fiber is sufficiently divided, and then determines the non-woven fabrics
The ultra-fine facial mask cloth of high resiliency multicomponent can be obtained wherein in type, and PA-6, PET and PLA in the filament ultrafine fiber cloth are super
There are different size of pore between fine fibre, these pores increase the ultra-fine cloth elasticity of long filament and drapability, make cloth cover
While meeting super soft plentiful, has good Degradable environment protection.Wherein, in the step 2, in the condition of high-temperature water
Under multicomponent composite filament handle, make season crack between component fibre；Without other any chemical treatments.Together
When, for fiber while abundant cracking is opened, fiber passes through the soft processing of secondary water, causes cloth cover finer and smoother, and patch skin is good.
Wherein, the superfine fibre cloth of the 3 D stereo bicomponent filament yarn shape structure has 3 D stereo reticular structure, continuously
Different size of capillary cavity is formed between filament multiple component superfine fibre silk, so that cloth cover produces more capillary gaps,
So that cloth surface is more plentiful, band liquid measure is significantly increased, and can sufficiently increase the uptake of Essence, to realize ultra-fine facial mask cloth
High resiliency, it is super flexible, at the same time, due to PLA introduction so that superfine fibre facial mask cloth have degradability, it is more environmentally friendly.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
