Description
Technical field
The present invention relates to field of nonwoven fabric technology more particularly to a kind of composite fibre nonwoven cloth operation pad towel and its preparation sides
Method.
Background technique
Non-woven fabrics is also known as non-woven cloth, is a kind of fabric for not needing spinning and weaving and being formed, only by textile staple
Or long filament is oriented or randomizing, forms fibre net structure, then using the methods of mechanical, hot sticky or chemical reinforcing and
At.Non-woven fabrics is widely used in the industries such as medical treatment, health, including operating coat, protective garment, disinfection infantees, mask, diaper, sanitary napkin
Deng being mostly using made of non-woven fabrics.
Currently, the three big fibers for nonwoven production include polypropylene, polyester and viscose rayon.Wherein polypropylene is it
In with fastest developing speed, proportion highest, the advantage is that: Young's modulus is high, elastic recovery is good, easy to wash easily dry, dimensionally stable
Property is good, intensity is high, heat-resist, wearability is good.But the disadvantage of polypropylene non-woven fabric is that hydrophily is too poor, moisture pick-up properties
It is bad, and skin-friendly is not very comfortably, to be used for medical and hygiene article, absorbency is poor, and comfort is insufficient, is easy to produce electrostatic
Phenomenon and by stain.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of composite fibre nonwoven cloth operation pad towel and its
Preparation method is that wood pulp cellulose and collagen-modified polypropylene fibre compounding are prepared non-woven fabrics using spun lacing reinforcing, this two
Between kind of fiber networking uniformly, twine and connect that effect is good, the non-woven fabrics prepared has good water imbibition, antistatic and soft, thoroughly
Gas, thickness is big, light soft, dry and comfortable moisture-inhibiting.
A kind of composite fibre nonwoven cloth operation pad towel proposed by the present invention, is made of the fiber of following weight percent: wood
Pulp fibres 40-60%, collagen-modified polypropylene fibre 40-60%.
The invention also provides the preparation methods of above-mentioned composite fibre nonwoven cloth operation pad towel, comprising the following steps:
The preparation of S1, collagen-modified polypropylene fibre: polypropylene, maleic anhydride and cumyl peroxide are mixed
It closes, it is dry, it is added in double screw extruder, melt blending, extruding pelletization, obtains modified polypropene pellet；By modified polypropene
Pellet, which is added in melt spinning machine, carries out melting extrusion, then drawn machine carries out spinning drawing, obtains polypropylene fibre；By polypropylene
Fiber is placed in tea polyphenols aqueous solution, is stirred to react, and is taken out, dry, obtains tea polyphenols modified polypropylene fiber；Tea polyphenols are modified
Polypropylene fibre is placed in collagen aqueous solution, is stirred to react, and is taken out, dry, obtains collagen-modified polypropylene fibre；
S2, thick shredding: wood pulp cellulose and collagen-modified polypropylene fibre are put into respectively in opener and slightly opened
Pine；
S3, mixing, smart shredding: the wood pulp cellulose handled through thick shredding and collagen-modified polypropylene fibre are added to
It is mixed in cotton blender machine, is then transferred in opener and carries out smart shredding；
S4, combing, networking: it carries out the composite fibre feeding carding machine after smart shredding to be combed into web, by web
It is combed again, networking；
S5, spun lacing are reinforced: being carried out spun lacing to web and reinforced to form non-woven fabrics base fabric；
S6, drying, processing: by non-woven fabrics base fabric drying, winding, be processed into operation pad towel to get.
Preferably, in S1, the weight ratio of polypropylene, maleic anhydride and cumyl peroxide is 100:3-6:0.5-1.5.
Preferably, in S1, the draw ratio of spinning traction is 4-7 times, spinning speed 800-1200m/min.
Preferably, in S1, polypropylene fibre is placed in 7-15% tea polyphenols aqueous solution, is stirred to react at 40-50 DEG C
2-4h。
Preferably, in S1, polypropylene fibre is placed in tea polyphenols aqueous solution, sodium hypophosphite is additionally added, is stirred to react；
Preferably, the additional amount of sodium hypophosphite is the 3-5% of tea polyphenols aqueous solution total weight.
Preferably, in S1, tea polyphenols modified polypropylene fiber is placed in 5-10% collagen aqueous solution, in 40-45
DEG C it is stirred to react 2-4h.
Preferably, in S5, spun lacing reinforcing is carried out to web using 6 type high pressure jet heads, spun lacing pressure is respectively set as
30-50bar、80-100bar、140-150bar、110-130bar、90-110bar、20-40bar。
The utility model has the advantages that a kind of composite fibre nonwoven cloth operation pad towel disclosed by the invention, is using wood pulp cellulose and collagen
What protein modified polypropylene fibre was mixed with, wherein containing hydroxyl, a small amount of carboxyl and aldehyde radical in wood pulp cellulose, have only
Special absorbability and imbibition ability and superior soft, antistatic performance, in collagen-modified polypropylene fibre due to
Contain on collagen there are many polar group carboxyl, amino, hydroxyl etc., it is affine with water height, it is easy to which that adsorbed water molecule has
Preferable hydrophily, and wearability, elasticity and obdurability are good, networking is uniform between this two kinds of fibers, by wood pulp cellulose and collagen
Protein modified polypropylene fibre remixes after thick shredding respectively, smart shredding, combing, networking, then combs networking, both improves mixing
Uniformity, reinforced using spun lacing, the good hygroscopicity of wood pulp cellulose and modified polypropylene fiber, twining between the two connects effect
Good, the non-woven fabrics prepared has good water imbibition, antistatic and soft, ventilative, and thickness is big, light soft, dry and comfortable
It is wet, improve its service performance.
In collagen-modified polypropylene fibre preparation, polypropylene and maleic anhydride are first subjected to melt blending, in peroxide
Under the action of changing diisopropylbenzene (DIPB), maleic anhydride is grafted on polypropylene, is obtained surface through melt spinning and is contained the poly- of anhydride group
Tacryl places it in tea polyphenols solution, and acid anhydrides can occur hydrolysis and react with the phenolic hydroxyl group on tea polyphenols, and secondary phosphorous
The presence of sour sodium can speed up the progress of reaction, and the introducing of tea polyphenols can assign the good convergence of polypropylene fibre, hemostasis, suppression
Bacterium, anti-inflammatory performance, then be dipped in collagen aqueous solution, tea polyphenols can pass through hydrophobic bond and multiple spot hydrogen bond and collagen
Association reaction occurs for albumen, to be grafted on polypropylene fibre, significantly improve the hydrophilic of polypropylene fibre, hygroscopicity and
Skin-friendly can absorb rapidly the liquid flowed out in operation, avoid cross contamination.
