Definitions
- the present invention relates to the technical sector of spinning and the manufacture of textile products from natural fibers of animal origin, and more particularly, but not limited to, the technical sector of the preparation and spinning of wool , and the manufacture of woolen textile products and articles.
- wool consists of a protein fiber, mainly eratin (amino acids).
- wool fiber is mainly composed of the cortex, which is covered by scales.
- the scales or cuticles are essentially composed of three layers, the epicuticle, the exocuticle and the endocuticle (from the outside of the fiber to the cortex).
- the cuticle is fixed to the cortex by a keratin cement.
- Times of the order of tens of minutes are sometimes mentioned, but these times are not applicable (or not with good results) and have never been used in industry.
- an oxidizing treatment often precedes the enzymatic treatment, which does not represent a satisfactory formula.
- the common objective of these techniques is mainly to fight against the felting of the fiber, which occurs by hooking the fibers together by their protruding scales. Logically, we therefore sought to eliminate the main factor of the felting, that is to say the scales, and / or to mask the residual roughness by a surface treatment with a resin.
- Patent application WO 89/03909 describes a process comprising a light chlorination and a treatment with Bacillus subtillis, at pH 5 and at 40 ° C, for about 60 minutes.
- a general problem of the prior art in addition to the serious implications of certain processes on the environment, in particular those using chlorine, is that the fibers are too little or too little free of scales and that the processes are very long. If the fiber is too little smoothed, a significant furrability remains, and it is necessary to try to remedy it for example by an additional step, therefore problematic and expensive, which consists in applying resin on the fiber so as to cover the scales. If the fiber is treated too powerfully, the cortex is attacked. On the other hand, the prior art does not allow satisfactory removal of the scales, except taking the risk of an overly powerful treatment which will damage the cortex.
- the problem which the invention has tackled is therefore the improvement of the treatments of such fibers, in particular wool, in order to improve the properties, mainly the softness and the resistance to felting.
- the invention provides a method comprising a general concept, a biochemical aspect and a mechanical aspect, which is based on a radically new approach to treatment, and leads to a fiber of a new type. Also surprisingly, the product new obtained has properties such that the entire chain of preparation of natural material and its spinning is improved and facilitated on an industrial level, which represents another decisive advantage.
- FIG. 1 shows in longitudinal section a wool fiber, and shows the cuticle, cortex and bonding cement.
- FIG. 8 shows a cross section of wool fiber, showing the external cuticles, the central cortex and the bonding cement.
- - Figure 2 which consists of Figures 2a, 2b, 2c and 2d, schematically shows a preferred embodiment of the method according to the invention.
- Figure 3 shows a comparison between a section of wool fiber treated according to the invention ( Figure 3 b) and a section of identical fiber, treated identically except that its treatment does not include a step of opening scales (Figure 3 a), at 2000 magnification.
- FIG. 4 shows a comparison between a section of wool fiber with open scales by the method according to the invention ( Figure 4b) and the same fiber with the closed scales ( Figure 4a).
- FIG. 5 shows a view of a section of a new wool fiber according to the invention, at 3500 magnification, showing the trace left by the imprints of the scales which have been detached.
- FIG. 6 shows the beginning of alteration of a section of the wool fiber, with attack of the cortex.
- FIG. 7 shows the end of the alteration of a section of the wool fiber, with bursting of the fiber.
- - Figure 9 shows a section of wool fiber undergoing flaking according to the invention (during flaking).
- FIG. 10 shows a section of wool fiber undergoing flaking according to the invention (at the end of flaking, the scales have not yet fallen).
- FIG. 11 shows the scales which, in the method according to the invention, detach themselves and fall into the treatment bath, before the "mechanical" step.
- FIG. 1 appended it can be seen that the flake (formed by the exocuticle 3 - the epicuticle is not shown - and the endocuticle 4) is linked to the cortex 1 by a bond of keratinous cement 2.
- FIG. 8 is a cross-sectional view of a fiber on which we find the external arrangement of the scales (3,4), the central core formed by the cortex 1, and the binding zone or keratin cement 2.
- the bonding area is much less regular than shown in Figure 1.
- the invention relates generally to a process of flaking of fibers of animal origin, of protein type, which comprises at least one step in which one significantly weakens or destroys the layer of "support” keratin cement. forming the connection between the flaking (cuticle) and the cortex.
- said step of weakening or destroying the keratinous "support" of the flake comprises a step during which an "opening" movement of the scales is carried out.
- an "opening" movement of the scales By “one operates a movement of" opening “of the scales”, one indicates the fact that one seeks to cause a fault or a beginning of fault between the flake and its "keratinous" support.
- the invention therefore also relates to a general method for treating the fibers considered, characterized in that it comprises a step in which the opening, as defined above, is caused, that is to say total or partial, part of the scales. It has been discovered that this stage plays a preponderant role in the process of embrittlement of the support of the flaking. The methods which incorporate such a step will therefore be clearly preferred.
- the invention relates generally to a method of enzymatic treatment of the fiber which consists in selectively attacking, by enzymatic route, the layer of keratinous cement serving as connection between the flaking and the cortex.
- the invention relates generally to a method which consists in combining an opening movement of the scales with a selective enzymatic treatment.
- the invention relates generally to the combination of the above methods with at least one mechanical treatment making it possible to detach those from the scales whose support has been weakened or destroyed by said methods.
- the invention relates to the new product which has been obtained by these processes, and which is characterized by a particular elimination of a certain number of flakes, leaving a surface state markedly different from that obtained in the prior art, in particular because it comprises scales which have not been eliminated or only partially eliminated, the imprint of the scales removed and, moreover, because the cortex has not been damaged.
- the invention finally relates to the methods of treatment, preparation and spinning of natural fibers, in particular wool fibers, as well as of treatment and preparation of textile articles such as combed wool ribbons and the like, incorporating at least one step of the methods described above, as well as textile articles, or knitted items, or otherwise produced by textile or other means, from fibers obtained by these processes.
- the invention results from a radically original approach.
- the term “keratin cement” or “support” will denote the assembly formed by the cement itself and the part of the cuticle which is liable to be attacked.
- significantly weakening here is meant the fact of weakening the support to the point that a subsequent mechanical treatment is sufficient to detach the scales from the cortex.
- a short enzymatic treatment of wool fibers (or other animal fibers) is carried out under conditions such that the enzyme will preferentially and selectively attack the "support” or "keratinous cement” layer.
- the invention therefore relates to a process for flaking animal fibers of the protein type, comprising a cortex and scales, characterized in that it comprises at least one step according to which the keratinous cement layer forming significantly is weakened or destroyed. connection between a sufficient part of the scales (cuticles) and the cortex.
- a sufficient part of the scales designates the statistical proportion of scales from which the advantages of the invention are observed. Completely surprisingly, it is sufficient that an extremely small percentage of flakes be weakened and detached according to the method of the invention. The minimum threshold seems to be around 2 to 5% of statistically treated scales. Values below about 2 - 5% do not give any significant advantage. Values above about 7-10% are very difficult to obtain.
- this percentage which is a "statistical" representation of the effect of the treatment according to the invention, consists in placing in parallel between 200 and 300 fibers of approximately 60 mm in length, and placing under the microscope a " section "of length about 6 mm from the beam thus formed. On each section, the effect of the treatment is observed. The scales are either detached, and then their "imprint” remains, or are not detached, and then remain either intact, very slightly attacked on the surface, or else are broken. We can then easily establish the percentage of "attacked” fibers, the percentage of "loose” fibers and the percentage of fibers not affected (except a slight attack on the surface).
- the fibers are taken individually from inside and outside the tuft of a batch of wool.
- the fibers are fixed parallel to each other on a cardboard window. They are straightened but not stretched.
- the preparation is positioned on a sample holder / it is immersed in an inert atmosphere of argon and then is metallized by sputtering of gold (Ion Sput ter 1100).
- Each fiber is observed on a single field. At least 100 fibers are observed per batch of wool. Observations are repeated on n independent lots
- the method according to the invention defined above is characterized in that the step according to which the keratinous cement layer is weakened or destroyed comprises a movement of opening a sufficient part of the scales.
- the invention relates to a method characterized in that said step comprises the combination of an opening movement of a sufficient part of the scales with a selective enzymatic treatment.
- the conditions of preferential attack of the keratinous cement are obtained when one combines an opening movement of the flake with the enzymatic treatment, and when also combined with a high ionic strength of the enzymatic treatment bath.
- a surfactant consisting of a synergistic mixture of ethoxylates and special products is known under the brand name VALSOL ((TM), ICI).
- VALSOL ((TM), ICI).
- Other surfactants or mixtures of surfactants are within the reach of those skilled in the art on reading the description and examples given here.
- the opening of the scales allows the penetration of the enzyme mainly at the level of the keratin cement layer ( Figure 2c).
- an additive is added capable of increasing the ionic strength of the bath.
- Such an additive will for example be a suitable buffer, such as a phosphate buffer, or a mixture of such buffers, or sodium hydroxide added until the desired pH is obtained.
- a suitable buffer such as a phosphate buffer, or a mixture of such buffers, or sodium hydroxide added until the desired pH is obtained.
- the bath will be very short and very little agitated.
- the wool will be agitated only slightly or not in the bath to avoid felting. Good efficiency is thus obtained even if the percentage of flakes removed remains surprisingly low, of the order of 3 to 10%.
- FIG. 2a represents a cross section of a wool fiber, before the treatment according to the invention.
- Figure 2b shows the fiber when the scale initiates the opening movement.
- a rupture occurs substantially at the interface between the endocuticle 4 and the keratin cement 2.
- “Substantially” means in this context that it is very likely that the break does not happen exactly at the interface.
- FIG. 4b clearly indicates the opening movement of the scales, compared with FIG. 4a.
- FIG. 2c shows, in hatched lines, a probable zone of enzymatic attack. It is almost certain that the keratin cement 2 esc attacked quite preferentially, according to the "wavy" arrows shown purely by way of illustration in the figure. However, it seems that The endocuticle is only very little, or not at all, attacked. As will be seen below, this attack takes place either after the opening, or simultaneously with the opening. . Figure 2 shows for simplicity the simultaneous attack with the opening, without limitation.
- FIG. 2d represents the section considered of the fiber substantially when the attack is finished.
- the keratin cement 2 and possibly a small part of the flaking were destroyed.
- the scale is therefore no longer attached to the cortex except by its base.
- the shape of the latter and its location are probably responsible for the existence of a characteristic "imprint" 7 after the flaking has disappeared, as will be seen below and as shown in FIG. 5.
- the invention therefore generally relates to a process for flaking animal fibers, characterized in that a statistically sufficient part of the scales is opened, before or simultaneously with an enzymatic treatment, in that the ionic strength is increased. of the bath before or during the enzymatic treatment, and in that the enzyme is allowed to act for a time sufficient to weaken or destroy the keratinous cement forming the "support" of the scales actually weakened, but insufficient to damage the cortex. It is believed that the selectivity of the process is due to the fact that the enzymatic treatment is carried out under a strong ionic force, equivalent to a phosphate buffer solution of molarity 0.05 to 0.2 M.
- one of the originalities of the invention is to penetrate the enzyme at the place selected for attack, thanks to the opening of the scales, at a time when the enzymatic activity is high because the ionic strength is chosen at a high value , and paradoxically without damaging the cortex.
- the enzyme will act effectively at the places where it has statistically penetrated, that is to say on the keratinous cement.
- the appraisal of the processing time by a person skilled in the art can be carried out using simple routine tests on samples, and using the general knowledge of a person skilled in the art.
- the contact time with the enzymatic bath is of the order of a few minutes, in particular two to six minutes.
- the method of the invention can be implemented according to all the variants accessible to those skilled in the art, and in particular in a single bath for opening and enzymatic treatment, or in two successive baths for opening the scales and then treating enzymatic, or in two identical successive baths (each comprising the step of opening and enzymatic treatment, with a dosage of approximately 1/2 of the enzyme in each bath), or in two successive repeated baths (opening then enzyme then opening then enzyme, with appropriate dosages and times).
- the decisive criterion will be to increase the probability that the scales are well accessible to treatment, for a maximum opening and detachment yield.
- the suitable enzymes according to the invention are known proteases, and mixtures thereof. Mention will in particular be made of a strongly alkaline protease known under the brand name MAXACAL (TM) from the company GENENCOR and a biocatalyst based on selected enzymes known by the brand name BACTOSOL (TM) from the company SANDOZ. Such enzymes and their mixtures can be selected by a person skilled in the art on the basis of present description and some routine tests, in particular by checking the criterion of fast and selective attack of the "support". It is in particular possible to carry out counts with the electron microscope of the percentages of attacked fibers, of fibers with raised scales, of "exploded" fibers, etc., as described above or by other methods.
- the concentration of enzyme (s) will be chosen according to the invention between 0.1 and 0.4%, preferably between 0.1 and 0.2%, by weight relative to the bath, that is to say approximately 5 to 10 times less than the manufacturers' recommendations.
- the most important factor according to the invention is the percentage of open flakes. This factor is more important than the time of enzymatic treatment or the enzymatic activity.
- optimal opening of the scales by a surfactant makes it possible to envisage a minimum enzymatic treatment time of the order of two minutes for different enzymes and different conditions, and a higher percentage of "open" scales, therefore a higher percentage of flakes removed.
- the process can be carried out by adding a separate step (or bypass), that is to say, for example, carrying out the treatment on washed wool, or deriving the wool during washing.
- the treatment can also be done following the washing operation of the raw wool. In this case, it is implemented following the last rinsing bath, in the same raw wool washing installation, by adding additional treatment tanks.
- the advantage of the invention is that it can be applied to raw fibers already washed in an aqueous medium, or in a solvent medium (degreasing), or also to ribbons of combed fibers, for example on the trowel, or to any other semi-finished, woven or knitted product.
- the conventional method and equipment can be adapted in order to optimize the benefits obtained.
- the new product has a spinnability, or aptitude for undergoing spinning, much greater than the spinnability of previously known products. We can thus clearly improve the steps leading to spinning, and the spinning itself. In particular, the operations are much faster than in the prior art. This is indeed the mark of a new product, original in itself by its structure, and more precisely by its surface condition presenting the imprints of the scales removed, and residual scales.
- the spinability of the new product according to the invention is close to that of cotton, which is the perfect model in this area (spinning at very high speed and nevertheless retaining "cohesion"), while wool untreated is, on the contrary, the opposite model (slow spinning, very strong cohesion due to scales).
- the wool according to the invention therefore becomes a product very close to cotton and superior to synthetic fibers, in particular polyester (very quick spinning because the surface is very smooth, but lack of cohesion), and also very much superior to the products obtained by "filing" of the scales, in particular by filing with chlorine such as Supersoft ⁇ TMI.
- this new product is more easily dyed than similar products of the prior art, in particular untreated wool. It is therefore possible to use less dye to obtain the same pitch. Furthermore, the treatment method according to the invention makes it possible to obtain a significant whiteness gain compared to the wool which has not undergone this treatment. Finally, as shown in the examples which follow, the process according to the invention gives textile fibers of animal origin, such as wool, good resistance to felting.
- the invention provides a product which is comfortable to wear, having, if desired, bright colors due to the dye affinity, and this by implementing an ecological process.
- the invention also relates to the fibers obtained by implementing the method according to the invention, as well as textile articles such as ribbons, threads, spun articles, knitted articles, and the like, made from said fibers whether they are considered as being obtained by the process according to the invention or as a new raw material per se.
