Abstract
Polyamide sterilization odour resistant fibre and manufacture method thereof, this fiber is a modified fibre.Used antiseptic is lanthanide rare (except the lutetium) Trichloroacetate and oxine complex, and it adds on production line in the polyamide polymer with the aqueous solution form that contains pyridine, and the weight of antiseptic is 0.01～1% of polyamide.The two in conjunction with after, again through spinning, drawing-off with add bullet and make antibiotic odourproof fiber.Antiseptic can be used for direct fabrics or indirect spinning.The advantage of product is to have lasting anti-bacterial anti-foul function and wash resistant; The advantage of manufacture method is, process stabilizing is easy and simple to handle, adds antiseptic on the original production line, must not increase equipment, the saving fund.
Description
The invention belongs to the modification technology field of synthetic fiber-polyamide 6 and polyamides 66 fibers.
Polyamide fiber has scuff resistance height, elasticity advantage big, that easily wash, therefore has many uses.It is quite big wherein to be used to knit the socks proportion.But this socks have individual shortcoming, because the sweat that the people secretes when wearing adds socks surface electrostatic absorption dust, under the condition of high temperature humidity, microorganism breeds rapidly, therefore produces foul smell, brings worry to people.Recently period, the person is many for development antibacterial deodourizing synthetic fiber, also obtains certain scientific and technological achievement.As Japan Patent JP59-112070, JP61-239081, JP61-258078, JP61-108774 etc., adopt different antiseptics to use the method that polyamide-based fiber is carried out post processing to reach the purpose of antibacterial deodourizing.Its weak point is that complex treatment process, anti-microbial property are not lasting, washing easily comes off.U.S. Pat 3.345.341 is that antiseptic carries out modification to daiamid-6 fiber with pentachlorophenate, and this antiseptic heat resistance is poor, surpasses 280 ℃ and is tending towards degraded or decomposes difficulty in spinning.And actual spinning temperature is 285 ℃.
The objective of the invention is, the polyamide (containing polyamide 6 and polyamide 66) with anti-bacterial anti-foul function fiber and manufacture method thereof are provided.
Technical solution of the present invention is, [it consists of Ln(ccl with lanthanide rare (except the lutetium Lu) Trichloroacetate and oxine complex
3Coo) (oxine)
2] be antiseptic, again antiseptic is deployed into the pyridine-aqueous solution (hereinafter to be referred as antimicrobial fluid) that requires concentration.This antimicrobial fluid is added to the back polymerization process of polyamide fiber direct fabrics quantitatively, makes antiseptic molecule and polyamide fiber molecular complex in the solution, make a kind of polymer-modified, again through spinning, drawing-off with add bullet and make polyamide sterilization odour resistant fibre; Or when indirect spinning, add, antimicrobial fluid and section are mixed, carry out spinning after the drying, can obtain the polyamide antibiotic odourproof fiber equally.
The allotment of antiseptic and use
One, the allotment of antiseptic
With granularity at the lanthanide rare below 5 microns (remove lutetium) Trichloroacetate and oxine complex [Ln(ccl
3Coo) (oxine) be solute], contain pyridine 0.1～10%(0.5～5% for good) water be solvent, be deployed into 10～30%(10～20% for good) aaerosol solution-antimicrobial fluid.During allotment, antiseptic will slowly add, and stirs.
Two, the use of antiseptic
The addition of antiseptic is that 0.01～1%(0.1～0.8% of polyamide raw materials weight is for good in spinning is produced) its Direct Spinning and spin addition and have any different, but all in above-mentioned scope.
Antiseptic can be added in the direct fabrics, also can be used for indirect spinning.
1, is used for polyamide 66, polyamide 6 direct fabrics.
With antimicrobial fluid under stirring condition from production line reactor exit quantitatively be injected in the reaction system, carry out melt spinning.2～8 ℃ of the more conventional temperature-averaging downward modulations of spinning temperature.The antiseptic addition is 0.05～1% of a weight of material, and its optimal addn is 0.1～0.6%.
2, the indirect spinning of polyamide 66, polyamide 6
After antimicrobial fluid and blank section fully mixed, the input rotary drum carried out vacuumize, screw spinning, moisture≤0.05% of cutting into slices; Grid melt-spinning, the addition of section moisture 0.3～0.4%, antiseptic is 0.05～1% of a weight of material, its optimal addn is 0.2～0.8%.
Principle of the present invention is:
Contain nitrogen, oxygen atom in the polyamide molecular structure, common duplet is all arranged, and the rare earth ion of sterilization can receive common electronics, carry out complexing between them, form the modified polyamide molecule, so this fiber has lasting anti-bacterial anti-foul function.
The present invention has carried out test of many times, and properties of product have been done test, and average index is as follows:
76 dtex polyamide long filaments
Physical index: powerful relatively: 3.7 lis of ox/dtex elongations: 35%
Anti-microbial property: (haloing determination method)
Bacterial classification: inhibition zone (millimeter) washing 50 inhibition zones (millimeter)
