Description

The aramid fiber of deposit-free finish
The invention relates to aromatic arginyl amine fiber is put in order, not only increased the fiber surface lubricity and improved the antistatic property of fiber, and can not make fiber lose normal feel.With the fiber of the present invention of regulation finishing agent arrangement, during fiber product processing, on the fibre bundle and on other zone of fiber process operation seldom or do not have a deposition of finishing agent.
Come out from fiber is manufactured, arrangement is applied to the fiber of the overwhelming majority.Put feel or the easing characteristic that is used to change fiber in order with ad hoc fashion; The result who obtains arrangement on the fiber of certain material often is very special.
As an example, the sylvite of alkyl phosphate is used as finishing agent for a long time to reduce polyester and nylon fiber electric charge and gather and to improve its feel.In fact, this class aliphatic phosphate partly is successfully used to the antistatic finish of aromatic arginyl amine fiber, but during fiber process, on other unit that they are deposited on the fibre bundle loathsomely and fiber process is operated.
Fatty acid ester, for example coconut oil, castor oil, polyethyleneglycol/di fatty acid ester are often used as finishing agent improving the lubricity of aromatic arginyl amine fiber, but these compositions can not help to reduce electrostatic charge.
The invention provides a kind of aromatic arginyl amine fiber product, it has the long filament DENIER of 0.75-3 or 5, and has evenly applied the sylvite of ethoxylated alkyl phosphate on fiber, and quantity is the 0.2-1.0% of aramid fiber weight.
The present invention also provides a kind of method for preparing fiber product, this method comprises sets up a liquid arrangement to bathe, body lotion contains the sylvite (in the gross weight of body lotion) of the ethoxylated alkyl phosphate of 1-50%, the aramid fiber that with Denier values is 0.75-5 is bathed contact with aqueous arrangement, dry then aramid fiber makes it evenly to be coated with the sylvite of the ethoxylated alkyl phosphate that applies 0.2-1.0% on fiber.
Fiber of the present invention is an aramid fiber, and it can prepare with any aramid polymeric material.Preferred fragrant acid amides is to fragrant acid amides, be poly-(right-phenylene terephthalate amine) preferably to fragrant acid amides, term " to (right-phenylene terephthalate amine) (PPD-T) refer to equimolar right-homopolymers that phenylenediamine and terephthalyl chloride polymerization obtain, also refer to the right-phenylenediamine that mixes a spot of other aromatic diamine and mix the copolymer that the terephthalyl chloride polymerization of a spot of other aromatic dicarboxylic acid chloride obtains.As a common rule, in preparation PPD-T, other aromatic diamine that uses and the maximum of other aromatic dicarboxylic acid chloride are about right-phenylenediamine or terephthalyl chloride 10% mole, or it is higher slightly, other diamines and the diacid chloride that provide do not have active group, therefore do not influence polymerisation.Fiber can be made into the short silk or the continuous filament yarn of any DENIER.
Fragrant acid amides manufacturing between aromatic arginyl amine fiber equally also can be used, preferred between-the Fang acid amides is poly-(-the different phthalamide of phenylene).Between-the Fang acid amides and-Fang acyl family amine fiber can be that 324 is described as U.S. Pat-3,287.To fragrant acid amides with to aramid fiber can be that 429 is described as United States Patent (USP) 3,869.
Usually, aramid fiber is to get with the spinning solution wet spinning of fragrant amide polymer, after spinning head is extruded, by or do not pass one non-solidify slit after, spinning solution solidifies in a water-based coagulating bath.Washing in many ways and dry after coagulation step, this is having tension force or is not having under the tension force situation and carry out.
Arrangement of the present invention is being applied on the aramid fiber during the fiber production, and applies after washing step usually.Certainly, finishing agent is the aqueous solution, is applied on the fiber by the aqueous solution that fiber is passed finishing agent, then dried fibres.Very possible is that aramid fiber is still " never being dried " form with the contacted while fiber of water-based arrangement bath.Fiber still keeps at least the water that brings from spinning process of about 20wt% before applying arrangement.Finishing agent is applied to more finishing agent is drawn in the fibre structure.Advantage of the present invention can be applied on the dry fiber that cross or that never be dried by finishing agent to be familiar with, and it is more effective than the arrangement that is coated on the fiber outer surface to believe that finishing agent is bonded in fiber.But preferred and more actual is that finishing agent is put on dry fiber.
In the yarn preparation, many fibers are owing to rupturing with fiber deflector roll or the contact of other gripping device, and yarn is owing to the formation of electrostatic charge is ruptured sometimes.Arrangement provides lubricant fiber and has eliminated electrostatic charge, has therefore reduced the damage of fiber, has improved the processing characteristics of fiber.In fragrant acid amides yarn production field, need more effective arrangement to improve process velocity significantly; It is very clear and definite needing more effective arrangement in the production of fragrant acid amides short fiber.
By using the RING SPINNING method that but discontinuous staple fibre is produced continuous yarn, this method briefly may further comprise the steps.
(ⅰ) open a position, the staple fibre of " package " machine compacting is formed loose staple fibre, continuous compacting becomes loose formula web and is called " lap in flakes ",
(ⅱ) mix (combing) lap, therefore, discontinuous staple fibre in fact parallelization and make these parallelizations staple fibre become loose continuous band, this is called " carded sliver ".
(ⅲ) carded sliver of row of mixing makes it to become one, and many, even a branch of being called " tensile bars ", independent here staple fibre can stretch by stretching-machine become many parallel relations.
(ⅳ) further stretch one or several tensile bars that combines make it to become a continuous line, and term is called " rove ", is having than under the low-tension rove being twisted by the Speed frames device; With
(ⅴ) stretch and further twisting, slubbing is to produce " yarn " on the RING SPINNING machine.The short suddenly yarn production technology of this multistep is because deposition yarn contact surface, carded webs for example, and draw roll, therefore the spinning roller has caused tangible fibre damage, and sedimental generation has caused fiber further to damage, roll cladding and reduced productivity ratio.
In further operation, for example heat treatment is reeled etc., and fiber is arranged to pass the deflector roll of row to carry out yarn arrays and layout.This further technology also can make fiber deposit on deflector roll equipment, and the problem that this deposit produces is just to have tension force to affact on the fiber because deposit produces when aromatic arginyl amine fiber passes, and produces friction between fiber and deflector roll.The present invention includes a kind of arrangement, its can improve finish solution the improved stability fiber electric charge and during producing short yarn in guide roller surface or producing and on other holder, produce deposition before or after can spinning.
Finishing agent of the present invention comprises a kind of sylvite of ethyoxyl aliphatic phosphate ester, particularly list or dialkyl phosphate.Aliphatic portion is the alkyl of 8-18 carbon in the finishing agent, and two or three chain ethoxy groups are arranged, and the finishing agent molecular structure is as follows:
Figure 901093629_IMG4
The monoalkyl dialkyl group
R=C wherein nH 2n+1(EO) 1-3
EO is the ethoxy group, and n is 8-18
Finishing agent composition of the present invention can react with phosphorus pentoxide by the aliphatic alcohol with 8-18 carbon atom and 2 or 3 oxireme groups, prepares with the potassium hydroxide neutralized product then.The oxireme group has increased the water-soluble of finishing agent, has reduced the generation of deposition.
As previously mentioned, finishing agent of the present invention be dissolved in excessive 50% or more water in, be benchmark with the weight of water.In any case the excessive dissolving of finishing agent material has been placed restrictions on and has been easy to emulsification or dispersion.The application of finishing agent of the present invention under the big portion situation, is bathed into arrangement by fiber is tilted and to be realized that this arrangement bath is prepared by the aqueous solution of finishing agent compound.In the arrangement bath, the concentration of finishing agent is such, and promptly when contact and arrangement bath drying are bathed in the arrangement of all others of consideration, fiber product will have the finishing agent of about 0.2-1.0%, and this is a benchmark with initial aramid fiber weight.For the great majority practice, during bathing, arrangement should comprise the finishing agent compound of 1-50%.
Because finishing agent of the present invention is water miscible, and can use with aqueous solution form, so it is just effective especially, solution application allows finishing agent to apply equably, and does not have too much or very few zone.But water-soluble is not unique quality index of the aramid fiber well handled.When having determined that the arrangement of water-soluble finishing agent puts on the aramid fiber for several times, the aramid fiber product of producing has level and smooth finish coating and good electrostatic property; When crossing the yarn contact surface, those arrangements on aramid fiber have stayed the deposit that generates continuously, the example of the water-soluble finishing agent of excess deposition thing that these stay on contact surface is a potassium alkyl phosphate, and at this, alkyl has 4-12 carbon atom; The sylvite of ethyoxyl alkyl amine sulfuric ester is tallow amine diethyl sulfide acid esters, comprises 2-20 ethylene oxide group at this ox ester; The alkyl phosphate of diethyl amine salt, here alkyl is the mixture of 8,10,12 carbon atoms; The sylvite of alkyl phosphoric acid ethyl acid esters is 8 carbon atoms at this alkyl.
Have to be noted that in the present invention the finishing agent that uses combines the monomer of top listed material, and become the finishing agent of premium properties, although other material of poor performance is made up of similar sometimes.
In fact, the aromatic arginyl amine fiber that the present invention is based on has the specific sorted material-sylvite of ethyoxyl aliphatic phosphate to show the combination of quality, and it has showed the combination of unique fiber and arrangement.
Test method
