Description
Technical field
The invention belongs to the technical fields of electrostatic spinning, more particularly to a kind of orientation beaming device, electrostatic spinning equipment
And nano-fibre yams preparation method.
Background technique
Electrostatic spinning is the technology when the most general spinning nanofiber of former, and product has very excellent property
Can, if any great specific surface area, it can neatly carry out surface-functionalized arrangement and excellent mechanical behavior etc., Ke Yiying
Use organizational project, wound dressing, drug release, filtering material, composite reinforcing material, sensor etc..Due to electrostatic spinning work
Skill is simple, and preparation flow is shorter than traditional conventional spinning, and product function is excellent, and it is special to obtain the U.S. from Anton formhals1934
Since benefit, electrostatic spinning is always the objective of the struggle of fibre science man and weaving developer for a long time.Such nanofiber
The leading products of China's new century will be become, market potential is huge, and prospect is very wide.
But up to the present, most of electrostatic spinning nano fibers are in the form of non-woven fabrics or loose orientation fibre bundle is received
Collect, due to its rambling structure, lower mechanical property, lacks loop bonding and volume production difficulty etc., it can not be with biography
It is to restrict the fundamental factor of its development that system textile fiber material, which has same extensive use (woven fabric, knitted fabric etc.),.From tradition
Fiber and textile industry it is known that gained after the bundles of nanofibers and its twisting of continuous single nanofiber and orientation
Yarn be only the developing direction of nanofiber.Since nano-fibre yams have, the degree of orientation was good, tensile strength is big, easily in recent years
In many good characteristics such as braidings, in terms of many application field biomedicines, engineering rack, conductive material, intelligence
Even there are better application prospect and prior value than conventional nanofibers non-woven fabrics (film).So efficient preparation structure
Controllable nano-fibre yams are only electrostatic spinning and reach widely applied final developing direction.
Have some scholars at present and have studied nanofiber and is collected in the form of fibre bundle or nanofiber is straight
The method for being processed into yarn is connect, and achieves some breakthrough achievements.Teo[Teo WE,Polymer,2007,48,3400-
3405] etc. prepare continuous oriented nanofibers yarn using liquid coagulating bath, this method is to lean on the eddy current effect of liquid to fiber
It is twisted, it is resulting therefore, it is difficult to control twisting point, twisting region and twist coefficient due to being difficult to control the vortex of liquid
The modulus coefficient of variation of yarn is larger, and twisting parameter is not easy to control, and is only applicable to the electrostatic spinning of non-soluble polymer.
[Afifi AM, Macromol Mater Eng, 2010 (295), 660-665] etc., Dalton [Dalton PD, Polymer,
2005 (46), 611-614] etc., Lee [Lee J H, Polymer, 2016,84,52-58] etc. be utilized respectively funnel type target, circle
The collection devices such as shape, circular ring shape prepare continuous oriented nanofibers yarn, these methods equally can not stability contorting twisting point and
Region is twisted, twist triangle zone is big, discontinuity, and revolving speed will lead to greatly fiber stress and increase and be broken, and fiber is straight
Diameter is relatively thick or both ends hold twisting preparation length of yarn it is too short, be unable to satisfy actual needs；Recent years, common preparation connected
The method of continuous oriented nanofibers yarn is double needle conjugation arrangement method, and Chinese patent 201310058070.8 discloses one kind and takes
This double needle conjugation arrangement method is used to electro-spun nanofiber yarn continuous preparation device and method.This resultant yarn side
Formula can continuously prepare oriented nanofibers yarn, but still lead to fiber unbalance stress broken end nothing in the presence of spinning twist triangle zone
The problem of method continuous production, so that the degree of orientation of preparation nano-fibre yams is uncontrollable, the twist is uncontrollable, resultant yarn poor continuity.
From the studies above as it can be seen that although the method for preparing Static Spinning yarn is relatively more, discovery is not received effectively really yet
Rice fiber yarn large-scale preparation method caters to industrialized production from now on.Being mainly manifested in existing method can not accomplish to receive
The twist triangle zone domain stability contorting of rice fiber.The presence of twist triangle zone makes fiber not only by longitudinal stretching force, simultaneously
Will also be by a horizontal drafting force, when one timing of longitudinal stretching force, the twisting angle of trigonum is bigger, suffered by single fiber
Power it is more big more be easy to happen fracture；Twist triangle zone length is bigger, and the non-gripping length of single fiber is longer, the weak ring of fiber
Problem is more serious.Therefore, twist triangle zone is bigger, is more easy to cause fibrous fracture, so that the basic parameter of yarn (twist by yarn
Degree, resultant yarn speed, fineness, bar evenness, strength etc.) regulation difficulty, causes Yarn break, it is difficult to which continuous resultant yarn can not be criticized
Amount preparation.
