Abstract
The invention discloses a kind of for silk fiber of non-woven fabrics and preparation method thereof, belong to non-woven fabric material technical field.The present invention uses pure natural mulberry silk, carries out water bath processing by lithium-bromide solution, washing using quick drying, makes silk internal stress quickly change, and prepares the modified silk with certain curvature.Modified silk material provided by the invention drastically increases the curvature of itself compared with former silk fiber, and strength has no and is substantially reduced, other the methods of being bonded by coating, blending, silk gum can be solved, it is one-sided to improve the shortcomings that cloth strongly causes the air-moisture-permeable of cloth, pliability is poor.This modified silk excellent material performance, it does not stimulate mildly, do not introduce other materials, the superperformance of fibroin fiber can be given full play to, it can be as the raw material of pure silk non-woven fabric, the frictional force tangled rate, improve unit area of silk in spun lacing silk non-woven fabric is improved, so as to be effectively improved the intensity of existing pure silk non-woven fabric product.
Description
Technical field
The present invention relates to a kind of for silk fiber of non-woven fabrics and preparation method thereof, belong to non-woven fabric material technology neck
Domain.
Background technology
Silk is a kind of natural protein fibre, containing to human body it is beneficial 18 in amino acid, protein content up to 97% with
On, fibroin is main body, and silk gum is coated on outside fibroin, plays the role of protection.Fibroin albumen is nontoxic, securely and reliably, tool
There is excellent biocompatibility, suitable exploitation is modified to new material.Wherein, serine, the threonine contained can slow down aging,
Leucine can speed up the metabolism of cell.These advantages that silk has so that researcher deepens to its modified material
Research, such as：Dipping, coating, grafting, blending etc., to assign silk different performances.
At present, when silk is as processing spun lacing pure silk non-woven fabric raw material, cloth strength deficiency is be easy to cause, cloth is easily torn
The shortcomings of splitting.Therefore, researcher is modified cloth, and current method has：（1）By the side for coating, impregnating strengthening agent
Method improves the strength property of cloth, but the air-moisture-permeable for being so easy to cause fabric declines；（2）By fusion method, will not take off
The dissolving of glue silk surface silk gum, then the strength for using silk gum silk being made to bond to improve cloth each other is dried, but this
The obtained cloth hardness of method is bigger than normal, and pliability is very poor；（3）The method that bending silk is prepared by saturation calcium salt improves silkworm
The bending degree of silk, increases the frictional force between silk, but this treated silk, and bending degree is inadequate, strength decline compared with
It is more, limit the strength of cloth.（4）By using the fibers such as terylene, tencel and silk carry out it is blended prepare non-woven fabrics, although cloth
Strength improves, but its practical value will have a greatly reduced quality.
Before the present invention makes, Chinese invention patent（CN100379915）" silk denaturated nonwoven fabric containing silk gum and its
In purposes ", silk gum is fixed on silk fiber using glutaraldehyde solution, while adding in surfactant makes it soft, although
Silk non-woven fabric can be made to improve strength, but in drying and cooling procedure, the melting and condensation of silk gum can cause cloth
Feel is poor, and the surfactant of addition may dissolve out stimulation skin, and the glutaraldehyde of addition is toxic, can bring stimulation and life
The decline of object compatibility.The Chinese invention patent of Publication No. CN105671790A provides a kind of silk hot-wind nonwoven cloth face
Material, is acted on using fusing point for the bond vitrified of 130 DEG C of ES fibers, and silk non-woven fabric is mutually bonded to play to increase by force with it
The effect of power, but high temperature can destroy silk fiber, while the addition of chemical fibre ES fibers, may be decreased the skin-friendly of pure silk
And biocompatibility.
The content of the invention
For the present invention for deficiency existing for existing silk non-woven fabric fabric, fibroin albumen material can fully be kept by providing one kind
The biocompatibility and strength of material, and with higher flexibility, the silk fiber available for non-woven fabrics and preparation method thereof.
Realize that the technical solution of the object of the invention is to provide a kind of preparation method of the silk fiber for non-woven fabrics, with family
Silk is raw material, successively after degumming, washing, drying process, then the processing followed the steps below：
（1）The dried domestic silkworm silk of degumming is immersed in containing in the protectant lithium-bromide solution of silk, temperature for 20 DEG C~
1 min of processing time~30min under conditions of 60 DEG C obtains swelling silk after silk absorbent solution；The lithium-bromide solution
Concentration is 3~8 mol/L；The silk protective agent is to include sodium sulphate, glycerine, the compound of saccharin and sucrose, silk protection
Agent dosage is the 1%~3% of silk quality；
（2）Silk roll compacting in the case where pressure is the pressure roller of 0.1 MPa~0.4Mpa will be swollen, removes extra swelling solution；
（3）Silk after roll compacting is fully washed with water, with the silver nitrate solution of 0.01mol/l to the bromide ion in eluate into
Row detection, until eluate is without precipitation；
（4）Silk after washing is placed in drying in the baking oven that temperature is 100 DEG C~110 DEG C, to constant weight, to obtain a kind of for nothing
The silk fiber of woven fabric.
In silk protective agent of the present invention, by mass, including 30%~60% sodium sulphate, 20%~50% sugarcane
Sugar, 5%~10% glycerine, 0.1%~5% saccharin.
Technical solution of the present invention further includes a kind of silk fiber for non-woven fabrics that the method for being prepared as described above obtains.
Provided by the present invention for the silk fiber of non-woven fabrics, curvature is 15~35%；Strength of filament is more than 4.5
cN。
The principle of the present invention is：The performance of portion swells can occur in lithium-bromide solution using domestic silkworm silk, promote silkworm
Silk fiber is fully swollen, and under the protectant protection of silk, control silk only occurs to be swollen and reduce the drop of fibroin to the greatest extent
Solution and dissolving.The silk of swelling is by washing removal lithium bromide and silk protective agent, thereafter rapid draing.It is swollen due to swelling
Stress is uneven when swollen stress is shunk with drying, causes silk bending winding, forms the silk material with certain flexing.This
Patent of invention prepares modified silk modified material using silk curvature method is improved, and sets about being modified from products material,
Improve the bending degree of silk, and then increase and tangle performance between interiors of products silk, be adapted as producing pure silk without
The raw material of woven fabric, available for preparing biological dressing, silk mask, silk sanitary napkin etc..
Compared with existing pure silk non-woven fabric raw material, advantage of the invention is that：
（1）The present invention can increase substantially the bending degree of silk, bending by carrying out lithium-bromide solution processing to silk
Degree can be increased to 15~35%.It is small to silk damage without using acid solution or lye due to the use of neutral salt solution, therefore will not
Injure the strength of silk itself.
（2）Set about being modified in itself from silk non-woven fabric raw material, can solve other by coating, blending, silk gum bonding
The methods of, the shortcomings that only considering to improve strength and the air-moisture-permeable of silk non-woven fabric, pliability, skin-friendly is caused to decline.
（3）The silk non-woven fabric modified material that the present invention is prepared, nontoxic, the introducing without any substance is solving
Certainly pure silk non-woven fabric strength deficiency, while improving the tear resistance of nonwoven cloth, can fully keep fibroin material
Biocompatibility.
