The degree of fibrillation and/or the tendency to fibrillation of lyocell fabric can be reduced by treating the fabric with a low-formaldehyde or zero-formaldehyde crosslinking resin, heating the treated fabric to cure the resin, and washing and drying the fabric. The treatment can be applied to dyed fabric.
Description
Background of the present invention
1. invention field
The present invention relates to reduce the original fiber degree of the fabric of making by Lyocell fibre and the method for fibrillation tendency.
2. the narration of relevant technologies
People know, the solution of cellulose in certain suitable solvent can be expressed to and make cellulose fibre in the coagulating bath.This extrusion solidification method is called " molten spinning ", and is called Lyocell fibre with the cellulose fibre that the method is made.One example of this method is described in United States Patent (USP) A-4, and in 246,221, its content is with reference in conjunction with in the present invention.With cellulose dissolution in a solvent such as a kind of uncle N-amine oxide (for example N-oxidation N-methylmorpholine).Gained solution is pressed through a suitable spinning plate and generates long filament, desolvates and drying through solidifying, wash to remove then.In a certain stage after solidifying, these long filaments are prescinded the generation staple fibre usually.People know that also cellulose fibre can enter in the regeneration coagulating bath by the solution extruding with cellulose derivative and make.An example of this method is exactly a viscose process, and cellulose fiber Wesy is cellulose xanthate in this method.This method of two types all belongs to wet spinning.Molten spinning than the method for other known manufacturing cellulose fibre viscose process for example has many advantages, and for example its environmental emission thing is less.
Here the Lyocell fibre of being said is meant the cellulose fibre that obtains with the organic solution spinning process, wherein used organic solvent is the mixture of organic compound and water on substantially, and moltenly in the method spins included cellulose dissolution and these two steps of spinning all do not generate cellulose derivative.Here " Lyocell fibre " said and " Lyocell fiber " are synonyms.Here the solvent spun fibre cellulose fabric of being said then refers to many woven yarn or the fabric that is knitted into, and some yarn at least wherein contains Lyocell fibre, all be this kind fiber or with the mixture of other kind fiber.
Fiber has the trend of fibrillation, particularly when dampness is subjected to mechanical stress.The generation of fibrillation is exactly that fibre structure is destroyed in the vertical, and the thin fibrillation of result has partly broken away from fiber, and fiber and the fabric (as woven or knit goods) that contains this kind fiber have just produced a kind of appearance of crinosity.The fabric that contains fibrillating fibre can have " unglazed " appearance after dyeing, be not suitable for requirement attractive in appearance.It is believed that this fibrillation is the mechanical wear effect of fiber in moist solvent swelling state processing procedure that result from.Fiber in for example boiling-off, bleaching, dyeing and the washing process, all can be subjected to the effect of mechanical wear at wet process inevitably.The treatment temperature height, the time is long, will produce fibrillation largely.As if the solvent spun fibre cellulose fabric is responsive especially to this wearing and tearing, so it compares with the fabric of other types of fibers cellulose fiber, find easier generation fibrillation.And COTTON FABRIC is by nature, and its fibrillation trend is very low.
European patent-A-538,977 point out, with the solution-treated of cellulase, fibrillation can be removed from the woven solvent spun fibre cellulose fabric of fibrillation.But cellulase is the enzyme material of the plain generation of a kind of accelerating fibers hydrolysis.But this processing does not resemble desirable so effective, and the disposal of used enzyme solutions also can cause environmental problem.
For many years, people just know that available crosslinking agent comes treatment of cellulose fabrics, increases its wrinkle resistance, for example, compile complete works of Encyclopaedia of ChemicalTechnology at Kirk-Othmer, 3rd ed., Volume 22 (1983), and Wiley-Interscience is entitled as in " fabric (arrangement) " (p769-790) joint, and at article H.Petersen, Rev.Prog.Coloraton, Vol 17 (1987), and introduction is all arranged among the P7-22.Crosslinking agent is used other title sometimes, as crosslinked resin, chemical finishing agent, resin finishing agent etc.Crosslinking agent is the small-molecule substance that contains many functional groups, and these groups can form cross linkage with the hydroxyl in the cellulose.In the arrangement process of routine, cellulosic fabric is to handle through crosslinking agent earlier, for example apply up by pad bath, and oven dry then, heating makes resin solidification and causes crosslinked (rolling-dry by the fire-roasting technology) again.Known these anti-crease finishing processing can make the cellulosic fabric embrittlement, and the result makes wear resistence, and tensile strength, TEAR STRENGTH all decrease.
First cross-linking system is once based on resins such as formaldehyde, ureaformaldehyde and melamino-formaldehydes.They have many problems.Because the existence of outside binding resin, these processing can cause the temporary transient sclerosis of fabric.Fabric through this processing is emitted niff easily when storing.These materials odorous comprise amine catalyst and the virose formaldehyde that is used for making hardening of resin.Therefore just think must the carrying out washing treatment fabric with the accessory substance of the resin of removing outside bonding and the resin generation that produces bad smell.But this washing and drying have subsequently just increased production cost.
Above-mentioned these systems mostly so-called by containing " low formaldehyde resin " and " zero formaldehyde resin " replace as the system of crosslinking agent.This class crosslinking agent has a kind of known classification, contains the small-molecule substance that the N-hydroxymethyl resin promptly contains two or more N-methylols or N-alkoxyl (especially N-methoxyl group).The N-hydroxymethyl resin normally uses together with selected acid catalyst, to improve cross-linking properties.In a typical method, with a solution that contains about 5-9 (weight) %N-hydroxymethyl resin crosslinking agent and 0.4-3.5 (weight) % acid catalyst pad in cellulosic fabric on, reaching pick up is 60-100 (weight) %, will make crosslinking agent sclerosis set through wetting fabric drying, heating then.Generally can't temporarily harden through fabric low or that zero formaldehyde resin is handled, also not send bad smell.Flat fabric through hardening and ready-made clothes seldom wash before being sold to client.
Summary of the present invention
A content of the present invention is to reduce the method for solvent spun fibre cellulose fabric fibrillation tendency, the steps include:
A) with a kind of crosslinked resin low or zero formaldehyde fabric is handled;
B) fabric is heated under proper condition, resin and cellulose are reacted;
C) with fabric washing;
D) with fabric drying.
In this content of the present invention and other content that below will state, fabric is to handle and heating reacts with the cellulose that causes resin and flat fabric form with cross-linking agent resin.One in this content of the present invention and other content may be in the embodiment preferred, and fabric washs with the form of flat fabric and be dry, therefore is suitable for cutting into the usefulness of tablet for clothes or other textiles manufacturing.In another embodiment of this content of the present invention and other content, be earlier fabric to be made clothes or other textiles, then through washing and dry to finish the process of the inventive method.
Second content of the present invention is a kind of method that reduces solvent spun fibre cellulose fabric original fiber degree, and it may further comprise the steps:
A) with a kind of crosslinked resin low or zero formaldehyde fabric is handled;
B) fabric is heated under proper condition, resin and cellulose are reacted;
C) with fabric washing;
D) with fabric drying.
The 3rd content of the present invention is that a kind of original fiber degree that provides is low, the method for the solvent spun fibre cellulose fabric that the fibrillation tendency is also low, and it may further comprise the steps:
A) fabric is carried out boiling-off and dyeing, thereby cause the fibrillation in the fabric;
B) with a kind of crosslinked resin low or zero formaldehyde fabric is handled;
C) fabric is heated under proper condition, resin and cellulose are reacted;
D) with fabric washing;
E) with fabric drying.
In this 3rd content of the present invention, fabric can be bleached between the boiling-off of step (a) and dyeing, and also maybe can insert a drying steps in step (a) with (b).In step (c) afterwards, fabric may show very high original fiber degree so that by the textiles of its manufacturing can commercial also be unacceptable.In step (e) afterwards, the fabric of open width knitwear or woven form, its original fiber degree is very low, can conform with commercial needs.
One class crosslinked resin preferably is the N-hydroxymethyl resin, some preferably the visible above-mentioned Kirk-Othmer of methylol example compile the article of complete works of and Petesen.For example have: 1,3-dimethylol ethylene urea (DMEU), 1,3-dimethylol propylidene urea (DMPU) and 4,5-dihydroxy-1,3-dimethylol ethylene urea (DHDMEU).Other example comprises the compound based on oolong, triazinone, carbamate.Another kind of crosslinking agent preferably is based on 1,3-dialkyl group-4, the compound of 5-dihydroxy (alkoxyl) ethylidene-urea and derivative thereof.The another example of suitable crosslinking agents is a melamine, and also having an example is ethylene-dimalonic acid (BTCA).Also can adopt multiple crosslinked resin.
Be used for that the crosslinking agent of cellulosic fabric anti-crease finishing normally uses altogether with a kind of catalyst junction.This catalyst works to quicken cross-linking reaction and sclerosis and set resin.Method of the present invention is when the catalyst that uses this effect of selected crosslinking agent appropriate to the occasion employing plaing.For example, the N-hydroxymethyl resin should with the acid catalyst logotype, this kind acid catalyst for example is a kind of organic acid such as acetic acid or inorganic acid such as zinc nitrate or magnesium chloride.Potential acid such as ammonium salt, amine salt and slaine also can use.Can also use hybrid catalyst system.
Crosslinking agent and any catalyst are preferably used solution (being preferably the aqueous solution) to be applied to fabric to get on.Solution is applied to more available known methods on the fabric, for example, solution can be padded on the fabric, and the processing that perhaps can make fabric pass through this solution is bathed.Fabric can be woven or knitted fabric.Solution should contain the crosslinking agent at least about 2 (weight) %, and % is advisable with 3-6 (weight).If use catalyst, its content can contain at least 1 (weight) %, 1-2 (weight) % is advisable.
Undertaken being about to the fabric heating and making crosslinking agent set sclerosis after crosslinked resin handles by the inventive method.Fabric also can carry out drying.Heating steps can be before drying steps, in the time of dry or carry out afterwards.Heating required time and temperature is decided by the character of used crosslinking agent and catalyst.Heating and or adoptable drying after, fabric can contain at least about 0.5 (weight %), better about 1.0 (weight) %, the set crosslinking agent of better about 2.0 (weight) % (calculating based on cellulose), but can not surpass 4 (weight) % usually.Usually find that 70-90% crosslinking agent in the wet fabric can be bonded on the cellulose.
The concentration of resin is to select according to the activity and the sclerosis efficient of this kind resin in the bath, and must obtains the quantity of required set resin on fabric.
After heating and set, wash and drying by the step that is generally used for cellulosic fabric.
It is generally acknowledged that crosslinking agent can reduce the abrasion resistance of cellulosic fabric, but press the fabric that the inventive method is handled, its original fiber degree is very low, and this is amazing especially.The inventive method needs another wet treatment step, and as previously mentioned, wet treatment step can cause solvent spun fibre cellulose fabric fibrillation.
Compare with untreated fabric by the fabric that the present invention handles, have fabulous antigen fibrillation performance.The fabric of handling by the present invention is suitable for making textiless such as clothes.This textiles can be washed and starched, and its fibrillation tendency still keeps very little, or only increases lentamente.
Method of the present invention can be applicable to dyed fabric, comprises that those adopt such as notifying the fabric that the rope dyeing method that causes mechanical wear dyes.This is an advantage of the present invention, because people know, fabric is carried out rope dyeing can improve the expanded and lax of fabric usually, causes good feel.Method of the present invention can be used for fibrillation, even the serious fabric of fibrillation, makes us finding uncannily very much, and after the fabric with very high original fiber degree was handled through the inventive method, its original fiber degree generally was very low.Concerning most of purposes, there have the fabric of very high original fiber degree to be considered to quality to be secondary, and the result carries out later processing and fabricating to it, all is not calculate on cost.The special advantage of the present invention is exactly to make the inferior fabric of this quality change first-class fabric of quality and textiles into.
Carry out the measurement of original fiber degree with 1 pair of material of method of testing described below.Method of testing 1 (fibrillation measurement)
The measurement of fibrillation does not have the recognized standard method.Adopted following method to ask fibrillation index (F.I.).The some fibre sample increased successively by its fibrillation degree line up.To each root fiber sample, measure a full-length.Count out the radical of fibrillation (by the outward extending very thin burr of fibrous body) then along this full-length, measure every fibriilar length again.It is long-pending that the fibrillation radical of every fiber be multiply by the fibrillation average length, a numerical value.The highest fiber of this product numerical value is considered to the highest fiber of fibrillation degree, and is defined as fibrillation index 10.The fiber that does not have fibrillation fully, its fibrillation index are decided to be zero, and remaining fiber is then planted equably according to the artificially number of measuring with microscopic method and come between 0 to 10.
With this fiber of measuring, just a kind of levels of the standard have been set up for the fibrillation index.If will measure the fibrillation index of any other fiber sample, the fiber of its 5 or 10 fibers and levels of the standard is estimated comparison at microscopically, the range estimation numerical value of each fiber is in addition average, draw the fibrillation index of tested sample.As long as range estimation relatively must be worth with average, than the fast manyfold of actual measurement, finds the fibre technology personnel skilled, and the result of its measurement is consistent.
Can extract the measurement that fiber carries out the fibrillation index from fabric face.F.I.% surpasses 2.0 to 2.5 woven and knit goods, and its outward appearance is promptly not pleasing.
The narration of preferred embodiment
To the present invention be described with embodiment below.In each example, the method for making of used not dried fibres is that the extruding of the solution of N-oxidation N-methylmorpholine (NMMO) is entered a water-bath, and then the fiber that washing generates is to being substantially free of NMMO.
Embodiment
Getting a kind of F.I. is 100% zero solvent-spun cellulose fine spining machine woven fabric, through destarch, boiling-off and jet dyeing machine dyeing.Destarch is that the aqueous solution with the 1.5g/l commodity starch enzyme preparation of pH6.5-7.5 carried out 45 minutes at 70 ℃.Boiling-off is to carry out 60 minutes at 95 ℃ with the aqueous solution that contains 2g/l sodium carbonate and 2g/l cationic detegent.Dyeing then is to carry out 120 minutes at 85 ℃ with a kind of aqueous solution that contains the HE of Procion naval (Procion Navy)-R150 dyestuff (Procion is the trade mark of Zeneca plc) (dyestuff weight be fabric weight 4%), 80g/l sodium sulphate and 20g/l sodium carbonate.Fabric is earlier at 70 ℃ subsequently, and the back is at the room temperature water rinse; With an aqueous solution that contains 2g/l Sandopur SR (Sandopur is the trade mark of SandozAG) go to soap at 95 ℃ (soap off) 20 minutes; Dehydration; Final drying.This step is the typical rope form processing procedure of cellulosic fabric.Fiber fibrillation through handling like this is very serious, and its F.I. is 4.5.
Use the aqueous solution of the low formaldehyde resin DHDMEU (supply from Hoechst AG, trade mark is Arkofix NG conc) of different content to pad in the sample of DYED FABRICS.This solution contains the catalyst that can discharge acid by this resin supply manufacturer's recommended, and its amount is 25 (weight) % of ArkofixNG conc.This fabric sample is then in 110 ℃ of dryings, 180 ℃ of 30 seconds of resin quick-hardening.Fabric sample is refilled jet dyeing machine, twice of preceding for another example boiling-off.Sample pads with a dispersion liquid that the polysiloxane-based softener of 50g/l (provided by Redolf Chemi-cals Ltd, trade mark is Rucofin AO736) the is provided cloth mangle that wets, again 110 ℃ of dryings again through dehydration.The results are shown in table 1.
Resin %w/w 0.0 1.0 2.0 4.0 6.0 8.0 was bonded to the tree 0.0 0.5 1.0 2.0 3.0 4.0 fat %w/wF.I. 5.8 1.9 1.5 0.5 0.4 0.3 on the fabric during table 1 was bathed
Anchor at the amount of resin on the fabric, its numeral is according to there being 70% active solid, 80% to shut out liquid, 85% value that estimates of sclerosis efficient among the Arkofix NG.
As can be seen, the F.I. of undressed fabric increases to 4.5 in above-mentioned those further wet process, and on the contrary, and in fact resin treatment reduces to commercial acceptable value promptly 1.9 and even littler with the F.I. of fabric by 4.5.
