(Technical Field) The present invention relates to a fabric with excellent abrasion resistance, tensile strength properties, and flexibility. (Prior Art and its Problems) Conventionally, as a method for producing a nonwoven fabric, a method has been known in which easily splittable fibers are used, split by needle punching or pressurization, and then entangled. However, in such conventional methods, one of the polymer components of the filament used is a polymer that is easily broken, a polymer that is easily soluble in chemicals, a self-adhesive polymer, etc. It lacked performance, and there was no thought of using it. For this reason, measures have usually been taken to either destroy and remove such component polymers, or to use them as adhesives. Since the nonwoven fabrics obtained by such conventional methods destroy, remove, or adhere to one component of the polymer, they do not have sufficient strength, flexibility, and frictional properties as fabric properties. (Object of the Invention) In view of the background of the prior art, the present invention was developed based on intensive studies in order to obtain a fabric in which all the polymer components constituting the filament act effectively as fibers and have excellent entanglement properties. The present invention was achieved by discovering that a combination of polymers not only achieves the above objectives but also exhibits properties with high added value. That is, the present invention stably provides a fabric that is excellent in abrasion resistance, tensile properties, and flexibility. Furthermore, according to the present invention, since the cross section of the split fibers has a shape with sharp edges such as a crescent shape or a semicircular shape, the fibers are more easily entangled with high-pressure water flow than a perfectly circular shape, and are easily disentangled. It has the characteristic of forming a stable fabric that is difficult to sow. Further, according to the present invention, even ordinary knitted fabrics can be easily provided with extremely high flexibility. Such a fabric has the characteristic that it can be made into a non-woven fabric or an animal hair-like fabric if necessary. (Structure of the Invention) (1) A multicomponent system consisting of polymers having different water swelling properties or incompatible polymer components, and having a structure in which at least two of the components occupy a part of the outer periphery of the filament cross section. A method for manufacturing a fabric, which comprises treating a fabric made of filaments with a high-pressure water stream. (2) Consisting of a multicomponent filament consisting of a plurality of polymer components having mutually different water swelling properties or incompatible polymer components, and having a structure in which at least two of the components occupy a part of the outer periphery of the filament's cross section. A method for producing a fabric, which comprises subjecting the fabric to a wet treatment and/or a pressure treatment, and then treating the fabric with a high-pressure water stream. Further, in the above two methods, a preferred embodiment is a method in which the polymer component is composed of at least two types selected from polyamide, polyester, and polyolefin. (Function of structure) In the present invention, polymers having different water swelling properties are polymers that, when individual filament polymers are kept in a wet state, have substantially different dimensions in the cross-sectional direction or longitudinal direction of the filaments. A combination of such polymers having a dimensional difference of 0.5% or more, preferably 1 to 5%. Next, incompatible polymers are combinations of polymers that separate at the interface when individual filament polymers are stacked together, thermocompressed at a temperature above the softening point of each polymer, and then allowed to cool. It will be done. An example of a polymer that undergoes substantial dimensional changes in the cross-sectional and longitudinal directions of the filament when placed in a wet state is polyamide. When polyamide is simply transferred from a bone-dry state to normal environmental conditions, it absorbs moisture and simultaneously swells, resulting in a dimensional change of up to several percent. On the other hand, examples of polymers that hardly undergo dimensional changes due to the above environmental changes include polyester and polyolefin. Here, examples of polyamides include nylon 6, nylon 66, and copolymers thereof, examples of polyesters include polyethylene terephthalate, polybutylene terephthalate, and copolymers thereof, and examples of polyolefins include polyethylene, polypropylene, etc. be able to. Therefore, examples of the combination of polymers having different water swelling properties in the present invention include polyamide and polyester, and polyamide and polyolefin. In the present invention, the mutually incompatible polymers are polymers having the above-mentioned property of not melt-bonding, and include, for example, polyester and polyolefin. However, the present invention is not limited to the above-mentioned polymer examples; for example, even if a combination of polymers other than these is used, the performance (water swelling property, incompatibility) of the above-mentioned polymers may differ. Any such polymer can be applied to the present invention, and it is of course possible to combine other polymers by adjusting the properties of the polymer through copolymerization, modification, etc. The multicomponent filament of the present invention comprising a plurality of polymer components is required to have a structure in which at least two kinds of component polymers occupy part of the outer periphery of the cross section of the filament. In other words, even if the fiber is a conjugate fiber made of a plurality of polymer components, the present invention can be applied even if there are differences in swelling properties or incompatibility, unless the structure is such that at least two components occupy the outer periphery of the fiber. No effect is produced. Such a cross-sectional shape includes a bimetallic structure, a shape divided radially from the center of the cross-section,
Hollow fibers in which a plurality of components are arranged repeatedly in a radial manner, fibers in which a plurality of components are arranged in a repeated stacked manner, or shapes in which at least one circular or non-circular dividing line is present in their shape, and the above-mentioned linear The parting line may be straight or curved, or a combination thereof. In the present invention, excellent dividing performance is achieved by dividing using a high-pressure water stream and, in particular, by combining polymers having different water swelling properties. Moreover, since all of the above-mentioned polymers of the present invention have fiber properties that can be sufficiently applied to clothing, they are characterized in that they exhibit their effects when made into ultrafine fibers. The multi-component filament of the present invention can also be used in combination with other filaments, fibers, yarns, etc. by means of blending, blending, blending, etc. By using such a combination, it is possible to produce a more attractive fabric. The fabric of the present invention may be anything that is generally referred to as a fabric, such as ordinary non-woven fabrics and woven or knitted fabrics, and may have any shape, shape,
Regardless of structure, thickness, etc. The present invention involves treating such fabrics with a high pressure water stream. The high-pressure water stream is a water stream obtained by injecting water from pores at high pressure. Such streams typically have a diameter of approximately 0.06 mm or more.
It is sprayed at a pressure of about 10-200 Kg/cm 2 through pores smaller than mm. This water flow usually consists of a large number of pores arranged in at least one row at equal intervals in the lateral direction (width direction of the fabric), or with the pores in each row arranged out of phase as necessary. used in the form of a stream of water. The fabric is supported by a receiving mechanism such that this water stream impinges vertically. This receiving mechanism is usually composed of a wire mesh or a plate-shaped body having a liquid draining structure, and is usually equipped with a constant-speed transfer mechanism such as a conveyor. Such water jet treatment may not be able to uniformly perform the treatment in one treatment, and in that case, it can be corrected by shifting the phase in the width direction of the fabric and performing the treatment one or more times. Note that it is a preferable method to automatically control such phase shift. Particularly when processing thick fabrics, it may be difficult to perform uniform division processing in the thickness direction, so in that case it is preferable to perform the processing on the front and back surfaces of the fabric. Note that by appropriately selecting the pressure of this water flow, the degree of division can be controlled, and part or all of the water can be divided as necessary. By selecting these pressure conditions, a wide range of fabrics can be formed, from, for example, knitted fabrics, in which the abundance ratio of ultrafine fibers can be freely changed, to non-woven fabrics, and animal hair-like fabrics. be able to. Such fabrics can be constructed by using polymer components that make up the multicomponent filament as having different resistances to the water flow, or by combining the filament with other fibers that have different resistance to the water flow. This can be achieved by employing fiber compositions such as mixed use. In the present invention, when performing the above-mentioned high-pressure water flow treatment, before performing the high-pressure water flow treatment,
It is also preferable to subject the fabric to a wet treatment and/or a pressure treatment. The wet treatment used in the present invention usually refers to immersing the fabric in water, and the water temperature in this case is 10°C.
The temperature above is preferably below boiling. The soaking time is selected based on the ease of dividing the fabric and the desired rate of division. In such a wet treatment, it is preferable to mix in water a drug that favorably affects fiber properties, a drug that promotes splitting, or an additive. Further, the pressure treatment in the present invention is carried out for the same purpose as the water swelling treatment described above, and is to facilitate division of the filament, and does not need to be under particularly high pressure. That is, it is sufficient if the filament can be strained to the extent that it can be easily divided by a subsequent high-pressure water stream. Such processing methods include, for example, a method of applying surface pressure between flat plates, or a method of applying linear pressure between a pair of rollers. In these cases, it is preferable that one or both of the pressurizing surfaces have an uneven pattern, but the effect will not be lost even if the surfaces are smooth. (Effects of the Invention) The present invention employs a fabric made of multi-component filaments that can be easily divided by high-pressure water jets, and also employs a specific combination of polymer components constituting the filaments that all act effectively as fibers. As a result, it was possible to easily and stably provide a fabric with excellent entanglement properties and excellent physical properties such as friction resistance, tensile properties, and flexibility. Since the filament fabric of the present invention is composed of fibers with sharp edges, it not only has excellent entangling properties, but also has the characteristics that the formed fabric is extremely difficult to unravel and has excellent stability. The present invention will be described in more detail below with reference to Examples. In addition, the measurement method in the examples is based on the method shown below. The sample used for measurement has a moisture content of 80-15%.
After dehydration, it was dried with hot air at a temperature of 105°C before use. [Degree of weaving] Cut the fabric at 5 locations in the thickness direction, count the number of undivided pieces X of 100 filament end cross sections exposed on the cross section using a microscopic method,
It is shown as the average value of the values shown in 100-X. [Abrasion resistance] Two pieces of fabric with a size of 5 x 20 cm matched to the direction were stacked in a flat shape with both ends fixed separately, and a surface pressure of 24 g/cm 2 was applied to the area of the upper fabric of 5 x 7.5 cm. The lower fabric was reciprocated in the longitudinal direction at a stroke of 2.5 cm and a period of 2 cps, and the number of reciprocating movements until fluff appeared in the friction area was expressed as the number of reciprocating movements. [Tensile strength] 5cm wide strip method. [Tear strength] Tongue method [Flexibility] Indicated by bending strength. 45° cantilever method. Example 1 A randomly arranged non-woven web (fabric weight 103 g/m 2 ) consisting of side-by-side type composite filaments with a fineness of 1 denier formed of nylon 6 and polyethylene terephthalate at a composite ratio of 1:1 was melt-spun and taken up by an air ejector. - Produced by collection method on wire mesh. This web is transferred to a conveyor made of 100 mesh wire mesh at a speed of 0.5 m/min, and
Water treatment was carried out at 65Kg/cm 2 . In this case, the water injection nozzle has a hole diameter of 0.1 mm and a number of holes.
500, the hole pitch was 1 mm, the hole arrangement was in one row horizontally, the stroke of nozzle swing (horizontal direction) was 2 mm, the period was 8 cps, and the distance between the nozzle surface and the web was 5 cm.
The water flow diameter on the web surface was 0.1 mm. After the above-mentioned high-pressure water treatment was carried out once, the web was turned over and the same treatment was carried out a second time. This treatment was carried out a total of four times, followed by drying treatment. The splitting degree of the obtained nonwoven fabric was 86%, and the split portions were split into filaments of 0.5 denier each having a semicircular cross section of nylon 6 and polyethylene talphthalate. The nonwoven fabric had a three-dimensionally entangled structure, had the properties shown in Table 1, and was suitable as a base material for clothing. Example 2 The same treatment as in Example 1 except that the randomly arranged nonwoven web made of the same side-by-side composite filaments used in Example 1 was immersed in warm water at 50°C for 10 minutes before the high-pressure water jet treatment. did. As shown in Table 1, the splitting degree is 95%.
