Abstract
The present invention discloses a kind of ES fibers without the multiple hydrophilic finish of silicon.Repeatedly hydrophilic finish is made of the no silicon emulsifier, wetting agent, antistatic agent, azochlorosulfonate propyl lycine, distilled water.The ES fibers and its non-woven fabrics prepared using the finish has the function of multiple hydrophilic, rapid osmotic, and environmentally safe, is mainly used as the surface material of baby paper diaper.
Description
Technical field
The present invention relates to a kind of no silicon, repeatedly hydrophilic finish, the ES fibers and its non-woven fabrics prepared using the finish are mainly used
Make the surface material of paper diaper.
Background technology
ES fibers are a kind of composite fibres being prepared by polyethylene and polypropylene.Repeatedly hydrophilic finish is to answer to ES fibers
For the auxiliary agent in ES fiber production process, it makes ES fibers have the performances such as excellent convergence, antistatic property, to make ES
Fiber can smoothly be processed into ES non-woven fabrics, and the non-woven fabrics formed has multiple hydrophilicity.
In recent years, the requirement with people to paper diaper comfort is continuously improved, and paper diaper technology is also constantly updated with suitable
Answer the demand in market.ES non-woven fabrics is chosen as the surface material of paper diaper with the excellent properties such as soft comfortable, gas permeability be good, but
Traditional ES non-woven fabrics does not have multiple hydrophilicity mostly, and urine is difficult to multiple quick penetration ES non-woven fabrics, this easily causes urine
It leaks out or urine is contacted with infant skin for a long time, comfort difference is caused even to cause diaper rash.Multiple parent currently on the market
Water finish is mostly siliceous hydrophilic finish, and permeability, the adsorptivity of silicon are especially strong, easily block skin pore, and it is strong to be unfavorable for skin
Health, and the surface tension of silicon is especially low, finish, which is discharged into environment, to pollute water environment.
Invention content
In order to overcome drawbacks described above, the purpose of the present invention is to provide a kind of ES fibers of environmental protection without the multiple hydrophilic oil of silicon
Agent.
The present invention the technical solution adopted is that：A kind of ES fibers are without the multiple hydrophilic finish of silicon, by following weight hundred
The component of point content mixes：7% emulsifier, 5% wetting agent 1,5% wetting agent 2,10.45-15.95% antistatic agents, 7-
13% azochlorosulfonate propyl lycine, remaining is distilled water.The azochlorosulfonate propyl lycine is 3- sulfopropyl dodecyl dimethyl beets
Alkali, structure are as follows：
Wherein, n=10.
Further, the emulsifier is polysorbate60.
Further, the wetting agent 1 is isomery fatty alcohol polyoxyethylene ether, the isomery fatty alcohol polyoxyethylene ether
Fatty alcohol alkyl chain carbon atomicity is 13, and polyoxyethylene (EO) adduct number is 8.
Further, the wetting agent 2 is straight-chain fatty alcohol polyoxyethylene ether, the straight-chain fatty alcohol polyoxyethylene ether
Fatty alcohol alkyl chain carbon atomicity is 12, and polyoxyethylene (EO) addition is 5.
Further, the antistatic agent is aliphatic alcohol polyoxyvinethene phosphate sylvite.The aliphatic alcohol polyethenoxy
The fatty alcohol alkyl chain carbon atomicity of ether phosphate sylvite is 12, and polyoxyethylene (EO) adduct number is 5.
Azochlorosulfonate propyl lycine of the present invention, azochlorosulfonate acid anion and quaternary ammonium root cation on main chain have had both the moon
The insertion of the property of cation, cationic head advantageously reduces the repulsion in micella between anion and increases the size of micella,
Micella becomes large-sized the Van der Waals force increased between finish and ES fibers, can firmly be adsorbed on ES fiber surfaces and be formed
Hydrophilic film, to realize resistance to washability.Wherein, the number of hydrophobic side alkyl number is inversely proportional with its infiltration rate.The present invention
By many experiments, screening determines the hydrophobic side alkyl number of the azochlorosulfonate propyl lycine, has finally reached its hydrophily and answer
Use standard.In addition, it has excellent wetability, bactericidal properties and biological degradability etc., it is applied to multiple hydrophilic finish, it can
The ES fibers and its non-woven fabrics for making preparation have excellent comfort.
Through a large number of experiments, the present invention selects polysorbate60 as emulsifier, can cooperate with antistatic agent and wetting agent, common to tie up
Hold the stability of multiple hydrophilic finish mixed system.
The present invention selects E13C-8EO as one of wetting agent, surface tension 27.2mN/m, and its hydrophobic side has
Branched structure can increase with the active force of ES fibers.
The present invention selects 12C-5EO as another wetting agent, and surface tension 22.9mN/m has been embodied ultralow
Surface tension, so the surface tension of multiple hydrophilic finish mixed system can be reduced with it.
Preparation method of the ES fibers provided by the invention without the multiple hydrophilic finish of silicon is as follows：By the weight percent, according to
It is secondary that emulsifier, wetting agent, antistatic agent, azochlorosulfonate propyl lycine, distilled water are added in reaction kettle, it is heated to 80 DEG C；Startup is stirred
It mixes, speed of agitator is 200 revs/min, is stirred 30 minutes, and each component is made to be uniformly mixed；It is cooled to room temperature, discharging.
Without silicon, repeatedly hydrophilic finish is water white transparency viscous fluid, no suspended substance to ES fibers provided by the invention；In room temperature item
3 months are placed under part without lamination；Solid content is 40 ± 1wt%.
Application process of the ES fibers provided by the invention without the multiple hydrophilic finish of silicon：It is normal with reference to ES fibers well known in the art
It advises oiling process to execute, no particular/special requirement repeats no more.
