Description
Technical field
The invention belongs to non-woven fabrics field, more particularly to a kind of super soft S/S solid double-component viscose non-woven materials and
Its preparation method.
Background technology
Non-woven fabrics (non-weaving cloth) is a kind of fabric that need not be spinned cotton and woven cloth and be formed, simply by textile staple or
Long filament is oriented or support is arranged at random, forms fibre net structure, is then reinforced using the method such as mechanical, hot sticky or chemical and formed.Letter
Single saying be exactly：It is not by one one yarns interwoven, woollen yarn knitting together, but by fiber directly by the side of physics
What method was bonded together, so, when the viscous title in you take your clothes, it finds that, it is that can not take out the end of a thread one by one.
Non-weaving cloth breaches traditional weaving principle, and with technological process is short, speed of production is fast, yield is high, low cost, purposes
Extensively, the features such as raw material sources are more, have a wide range of applications in daily production and life.
Spun-bond process increasingly occupies an important position as nonwoven production technology with the fastest developing speed at present.It is
Using synthetic fiber spinning principle, continuous filament fibers are made to lay into net during polymer spinning, fibre web is through machinery, chemistry or warm
Method is reinforced and forms non-weaving cloth.Spunbond production technology is applied to terylene, nonwoven polypropylene fabric history for many years.
The technological process of polypropylene spun-bonded non-woven fabrics is as follows：Polypropylene chip-melt spinning-air drawing-pendulum wire
- winding is reinforced into net-hot rolling.
But current non-weaving cloth cannot also meet some specific demands in pliability, particularly with medical and health use
Cloth, such as sanitary napkin, can make human body sensory uncomfortable.But this fiber or long filament can produce quiet because of friction in process
Electricity, obstacle and trouble are brought to subsequent handling, are unfavorable in the carrying out of production, while in use, as electrostatic,
Inconvenience is brought to user.Generally requiring carries out soft treatment, and its soft treatment is typically added or rear whole by master batch
The method of reason is carried out, and causes that the pliability of non-woven fabrics is improved by reducing interfibrous coefficient of friction.But obtained in the method
Material feel is not especially smooth, and not water-fastness, and the time that softness is maintained when using is not high.Chinese patent
CN201110412625.5 also discloses that a kind of super soft non-weaving cloth and its manufacture method, and the method is using changing material
Formal structure makes material become soft, and this preparation method can also influence the strength of material, reduce its service life.
The pliability of spun-bonded non-woven fabrics how is improved, how the pliability of spun-bonded non-woven fabrics softness as silk is brought up into
Degree, as the technical barrier that non-woven fabrics industry is commonly encountered.In addition, though formula use in the industry at present plus soft can be in certain journey
The pliability of product is improved on degree, but pliability is limited, additionally, to take into account the intensity of product, pliability, smooth degree and criticize
Amount steady production is even more in the industry cannot be while the problem for solving.
The content of the invention
The technical problems to be solved by the invention be to provide a kind of super soft S/S solid double-component viscose non-woven materials and its
Preparation method, prepared material has splendid comfort level and pliability, and its third dimension is stronger, and deformation behavior is small, breathes freely
Property is more preferable.

5cm, longitudinal elongation at break rate 90-120%, longitudinal bending stiffness 200-800cNcm, buckling length 2-4cm are laterally strong
Power 50-180N/5cm, transverse breakage elongation 60-100%, transverse curvature rigidity 160-480cNcm, transverse curvature length 3-
7cm, the three-dimensional thickness of material is 0.5-2mm.
Wherein, the preparation method of the non-woven fabric composite material, comprises the following steps：
(1) Masterbatch for taking polypropylene a, the softening agent of half amount and half amount respectively in proportion is stirred by whisking machines
Form mixed material A；The Masterbatch of polypropylene b, the softening agent of second half amount and second half amount is taken respectively in proportion by stirring
Machine stirs to form mixed material B；
(2) mixed material component A is fed into a screw extruder, is melted at 240-290 DEG C；By mixed material
B component is fed into an other screw extruder, is melted at 220-270 DEG C；By two melts of screw extruder extrusion
Fondant filter filtering is transported to respectively through melt pipe, measuring pump is sent into afterwards, entered into through the accurate measurement of measuring pump
Subsequently into spinning die head, spinneret is carried out by the die head of block form, side-by-side bicomponent fiber is sprayed, when by cooling box
Be cooled after the cooling of wind carries out air drawing and forms helical fiber by pipe type air flow drawing device, and then fiber passes through
Distributor is evenly distributed on spinneret, fluffy fleece is formed, by being transported to hot rolling after the preliminary reinforcing of pressure network roller
Technique is shaped by hot-rolling mill hot rolling, is then cooled down by chill roll, and heat is carried out by blancher, and finally winding cutting is coiled i.e.
Can.
The temperature of the hot rolling is 130-180 DEG C, and pressure is 0.4-0.6Mpa.
