Patent CN 105012999A are that, with sodium alginate as raw material, copper sulfate solution is solidification liquid, prepared by wet spinning
Copper alginate fiber, then degreasing cotton fiber and copper alginate fiber are carried out into blending, raw material and the basic phase of the application of its yarn
Together, distinguishing the main yarn raw material in patent CN 105012999A does not have pretreatment process (mainly copper alginate fiber),
Also particular design is not carried out to opening picking, carding process；And the cotton fiber for using is absorbent cotton, the yarn that rear blending is formed is not
The index of quality is given, the application in gauze and bandage field is only given at, it is impossible to which the application in field is commonly being taken in realization.
By taking 19.44tex cottons/copper alginate fiber 80/20 as an example, contrast table 1 and do not give fiber pretreatment implementation
Journey and finished product effect, referring specifically to shown in table 2.
The yarn main performance index table of comparisons under the different implementation conditions of table 2
Note：D1 in table 2 in comparative example 1 plus any fiber pre-treatment situation.
Be can be seen that with the contrast of table 2 by table 1：
(1) effect of sequence number 1-40 and D1 can be seen that whether under the conditions of what in contrast table 2, pre- using the application
The performance that copper alginate fiber after treatment carries out blending resultant yarn is superior to the technique for being pre-processed.
(2) influence that auxiliary agent is constituted：Whether pure soft finish or pure hydrophilic infiltration finish, its resultant yarn to yarn
Can all have and have some improvement, but pure soft finish is used alone, it is impossible to finish uniformly penetrating is entered copper alginate fine
Dimension aggregate, the stability spun of fiber is bad；Pure hydrophilic infiltration finish is used alone, to the softness lubrication of copper alginate fiber
Performance is not significantly improved, therefore suitable softness finish should be selected to be compounded with hydrophilic infiltration finish.When soft finish with
The volume ratio of hydrophilic infiltration finish is less than 1.5:When 1, soft finish consumption is very few, and the fragility of fiber fails to be changed very well
Kind, yarn forming performance is poor；With soft finish and it is hydrophilic infiltration finish volume ratio gradually increase, when soft finish with it is hydrophilic
The volume ratio for permeating finish is higher than 1.5:When 1, its resultant yarn ultimate strength and evenness fault performance gradually improve, and especially work as softness
Finish is with the hydrophilic volume ratio for permeating finish between 2:1-3.5:When 1, yarn forming performance is stablized relatively；But continue to increase the ratio,
When soft finish is higher than 3.5 with the volume ratio of hydrophilic infiltration finish:When 1, especially when soft finish and hydrophilic infiltration finish
Volume ratio is higher than 4:1, the effect enhancing of soft finish, fiber is excessively soft, easily occurs tacky phenomenon between fiber, deteriorates resultant yarn
Energy.Therefore, when soft finish is controlled 2 with the volume ratio of hydrophilic infiltration finish:1-3.5:When 1, yarn forming performance is optimal.
(3) influence of water temperature：When water temperature is less than 45 DEG C, because the activity of auxiliary molecules is not enough, cause health effect not
It is good；With increasing for temperature, when water temperature is higher than 45 DEG C, especially when water temperature is higher than 50-60 DEG C, the activity of auxiliary agent is with stabilization most
Good, health is worked well, and the fragility of copper alginate fiber is improved very well, resultant yarn fracture strength is higher and evenness fault compared with
It is low；But when temperature continues to raise, when temperature is increased to more than 65 DEG C higher than 60 DEG C, especially temperature, the stability of auxiliary agent
It is affected, so as to reduce this health effect, yarn forming performance reduction.
(4) addition of the composition of healthy liquid and healthy liquid, conditioned time form mutual verifying relationship, and the shadow of healthy liquid
Ring and depend on composition, water temperature and the auxiliary agent of auxiliary agent and the percentage of water again, addressed before the above two influence, this place master
Will be with the percentage of auxiliary agent and water as emphasis is commented, auxiliary agent is Main Function composition in healthy liquid, when its ratio is higher, cost
Higher but not notable to the resultant yarn influential effect of yarn, integrated cost is considered with resultant yarn effect, and auxiliary agent is suitable with the volume ratio of water
Control is 1:Less than 2；But the addition of water is also unsuitable too high, and the concentration of otherwise healthy liquid is too low, health effect on driving birds is not good；Therefore,
Considering for the factors such as integrated treatment cost, process cycle and treatment effect, preferably controls 1 the volume ratio of auxiliary agent and water:4~1:
2nd, water temperature control in 50~60 DEG C, the weight of healthy liquid and copper alginate fibrous raw material than control 1:20~1:10th, during health
Between control at 18~30 hours.

Dynamic feeding hopper and single beater scutcher are processed, in processing procedure, closing roller card wire opener, single beater scutcher
All hired roughneck's bottom drains；Strike gauge is gripped using half, striking point and the distance for gripping point are 25~45mm, striking point and gripping point
Distance increase by 40~60%, maximizing avoids copper alginate fibre damage；The blow speed of the hired roughneck of single beater scutcher
It is 480~680r/min, reduction amplitude is spin cotton 65~75%, reduces too small can formation to marine alga copper fiber and damage, produces
A large amount of short flannels, reduced conference and cause fiber block shredding impermeable, the normal combing in road after influence.
(2) carding step partly grips licker-in release using controllable type, and cotton carding eedle cloth is small and low density using operating angle
Pin tooth；Feed plate raises 10~15mm, and a large amount of short flannels are produced due to gripping shredding to reduce, and too low short fiber content is higher, too high
Shredding effect deteriorates；Reduce point a comb part speed, 700~750rpm of licker-in speed, 250~280rpm of cylinder speed, doffer speed
18~22rpm, too fast short fiber content is higher, and excessively slow shredding effect deteriorates；50~80mm/min of cover plate speed, too fast flat strips amount increases
Plus, too low cotton knot increases.
Be can be seen that using the implementation condition of the application using the implementation result of the application and comparative example, can be very good
Copper alginate fiber is reduced to overwhelm intensity, and maximized reduction copper alginate fibre loss, compared with comparative example, overwhelm
