Description
Technical field
The present invention relates to a kind of preparation methods of easy cleaning high water absorption Wiping material, belong to Wiping material technology of preparing neck
Domain.
Background technology
With the continuous improvement of people's living standards, requirement of the people to quality of life is also higher and higher.Wiping material is made
Can not only be preferably that people save time, rapid clean article for the consumables of daily life.But current Wiping material water suction
Property it is poor, dirt-removing power is weak, wear no resistance, cleaning the problems such as being not thorough.Wiping material and people's life are closely bound up, and type is very
It is more, according to the structure feature of Wiping material, it is broadly divided into following a few classes：Dry goods can be subdivided into woven species and knitted fabric again
Class, woven species are interwoven by filling yarn, and structure is relatively close, intensity is high, a resistance to long property is good, but in wiping process certainly
Body is easy to be contaminated, and not easy cleaning, and to generate cross contamination, reusability is poor.Using woven made from Common synthetic fiber
Object dirt-removing power is poor, and feel is harder, and easy damaged is by the surface of wiping article, the especially skin covering of the surface of easy damaged optical instrument.Knitting
Species be formed by coil clasp joint, its main feature is that plane any direction all have prodigious extensional performance, fabric
Gap is larger, and species Wiping material is generally thicker for knitting, loose, soft, good water absorption, but knitted fabric is easy hair loss, to make
At by the pollution again of wiping article.Non-woven dry goods Wiping material mostly uses chemical adhesion, heat bonding, needle thorn, spun lacing or wet method
Etc. techniques be process.Since non-woven material has special three-dimensional structure, there are larger holes between fiber, therefore such
The structure of Wiping material is more loose, and the range of thickness is big, adapts to different purposes.It is reinforced by chemical adhesion non-woven
Cloth, the adhesive of surface cure may make to be wiped article surface damage, and problem of environmental pollution can be also brought in process.Stationery
The general wood pulp for using good hygroscopicity, is made up of paper technology.Loosely, thin and strength is relatively low for structure, especially wet strong
Power is relatively low, and flexible towelette usually exists to fall to consider phenomenon to be worth doing.Complex class Wiping material is typically to certain special purposes or performance
Improvement, formed by the Material cladding of two or more different structure.Good water absorption, but poor durability.
Invention content
The technical problems to be solved by the invention：It is poor for Wiping material water imbibition, dirt-removing power is weak, wear no resistance, clearly
Clean halfway drawback, provide it is a kind of first by china-hemp fibers soda boiling carry out degumming, obtain degumming flax fiber, then take natural silk degumming

After 10 are mixed 10~15min, 3~5min of microwave treatment, obtains spinning solution under 180~220W power, using electrostatic spinning,
It is 15~20kV in voltage, it is 10~20cm to receive distance, and metal mesh is as carrying out spinning under conditions of receiving screen, you can obtain
Fibroin/PLA Composite Fiber；
（4）By the fibroin/PLA Composite Fiber and step of above-mentioned preparation（1）Spare degumming flax fiber, by quality
Than 1:1 mixing, it is 150~180 μm of composite fibre to obtain fibre fineness, uniformly sprays mass fraction 1,0%0 on composite fibre surface
Dialkyl benzene sulfonic acids sodium solution makes composite fibre humidity up to 40~50%, is then twisted blended yarns, by blended yarns using double
It is 80~120g/m that face knitting, which causes density,2Fabric, shaped, cut, you can obtain easy cleaning high water absorption Wiping material.
