In addition to the well-known methods of weaving, knitting, and weaving, there are many ways to make non-wovens today: methods. This material is made of synthetic and natural fibers. Various methods have been used to transfer fibers to the four thermal bonding methods using heat. D also has other bonding methods such as stitching and water needle method or jet net method. The water needle method or the jet phase method is a technique that was asked only in 197 Gindai. The method involves forming a fiber web by dry spreading or clear spreading, and then tangling the fibers under pressure with a small jet of water. Several rows of water jets are directed towards the fiber web, and the web is carried by a moving wire mesh or drum. The most tangled fibrous web is dried. Various types of fibers and fiber mixtures are used in the hydro-needle method.

In order to form a sheet of composite material by the water needle method, the correct properties for this purpose are to be tangled. One of the key factors of the right stem is the flexural rigidity of the fiber, where the initial or elastic modulus of the M fiber, and! Is the moment of inertia. The moment of inertia # is the number of sections (mdV64 for circular sections) depending on the fiber diameter. So the initial modulus is a material parameter, and the initial modulus is related to temperature. Rigid fibers are more difficult to tangle and require a higher cohesion ratio solution (kWh / mouse) than soft fibers, thus limiting the range of fibers that are technically and commercially available for this technology. The hydro-needle method has shown fibers made of thermoplastic polymers such as polypropylene, polyester, and polyamide. The properties of thermoplastic materials and other synthetic fibers are related to the nature of the polymer used and the type of manufacturing method. Often, polymer properties cannot be used. Instead, compromises are required due to process technology limitations. It is extremely difficult to manufacture extremely powerful and at the same time Fibers with low initial modulus. Most of the fiber strength is determined by the directionality, and the initial modulus also follows the same trend. That is, high fiber strength is accompanied by high initial modulus. 41 9 3 8 Manufacture of non-woven fabrics, so that water under high pressure is forced through the porous carrier to face a piece of fiber suspension to obtain tangles of the fibers.

Description of the invention (3) Spray or super hot water vapor spray is used to melt and tangle the fibers. If the spray gun commonly used in the water needle method is used, it needs to be hot enough to melt the meltable components mixed in the fiber sheet. Thus WO 95 / 〇6769 illustrates a method whereby a certain amount of melting of the meltable component can be achieved on a regular basis. Such a meltable component may be a fiber itself or a meltable component added in the form of powder or granules. However, the pure water needle method is not described. US 3 322 584 describes a fusion bonding method for bonding two plastic sheets together. The method can also be used to bond two layers of plastic fibers together. It is also known as the dissolving method, and the temperature used is enough to melt the fibers. US 5 069 735 describes a method of fusing adjacent flakes or fibers to solve the problem that flakes are often clustered and not suitable for this operation. US 3 192 560 describes a fusion bonding method in which fiber threads are controlled using a suitable medium such as water vapor or super hot water vapor, and the temperature is maintained at about or slightly below the melting point of the fiber threads. One problem with the water needle method is that the fiber components used must have flexural rigidity, so the fibers can be tangled with reasonable capacity. This means restrictions on the type of fiber used, and the necessity to use fine fibers or fibers with low initial modulus, even if the fiber itself is not optimal for forming a fiber web or for the function of the finished material. An object of the present invention is to achieve a method for manufacturing a non-woven fabric by a water needle method, in which the flexural rigidity of a practical fiber component does not limit the degree of entanglement as previously described. An additional object of the present invention is to achieve a method which can produce non-woven fabrics with coarser fibers, which consumes less energy or is stronger than today's methods. This paper size is in accordance with Chinese National Standard (CNS) M specification (21 × 297 mm) (Please read the precautions on the back before filling this page) • 、 R line 丨 6 522188 V. Description of the invention Another objective is to provide a highly fluffy non-woven fabric with special properties such as good mechanical properties. SUMMARY OF THE INVENTION The man on the 7th found that by increasing the temperature at this moment of tangling, the flexural rigidity of the fiber can be reduced. High degree of entanglement. July people also found that the initial modulus is only too high at the moment of entanglement to constitute a shortcoming. By only reducing the initial modulus during the entanglement itself and then allowing the initial modulus to return to the original level, provide-a kind of Methods and materials that have greater advantages over previously known materials. Cars need to compromise on the fiber manufacturing method. Instead, the fiber strength can be completely optimized. At the same time, it can be selected based on markings other than the restrictions imposed by the tangled method To bond fabrics. Many examples preferably contain rigid fibers in the finished fabric depending on the material to be used. Fibers that are very suitable for accepting the water needle method are more ideal Provide improved material properties and / or consume less energy in the manufacturing method. According to the present invention, a water needle method for manufacturing non-woven polymer fibers is achieved. The polymer fibers are provided in the water needle method instantly equal to or exceed the polymer fibers. The glass transition temperature is lower than the melting point of the polymer fibers. According to the present invention, a water-knitted fabric contains polymer fibers, and the polymer fibers in the fabric have an initial modulus of -50 centimeters / taxi (cN / tex) In addition, the water needle polymer fiber fabric obtained according to the present invention has a volume specific gravity of -8 cm3 / g. ---------------------------- -:… Packing: ...

Description of the invention (5 Other specific embodiments are disclosed in the appendix to the scope of the patent application. Detailed description of the invention The polymer fiber according to the invention is heated, so the instant of tangling reaches a temperature higher than the glass transition temperature (Tg) of the polymer fiber. At this temperature Increased molecular mobility To the extent that rigidity is severely affected, the elastic modulus or the initial modulus can be reduced by as much as a power of 10. The mechanical properties of synthetic polymers and the glass transition temperature of polymers are extremely changed. By the water needle method Instantly heating a predetermined fiber to a glass transition temperature or slightly higher than the glass transition temperature, the flexural rigidity and degree of entanglement of the fiber fabric are raised. A variety of different types of polymer fibers and their mixtures are used. According to the present invention, non-woven fabrics are particularly preferred. Or partially contain synthetic polymer fibers or a mixture or copolymer of such polymer fibers. The type of fiber and the percentage of natural fibers are selected based on the use of the non-woven fabric. The higher the percentage of synthetic polymers included in non-woven fibers, the higher the percentage The greater the likelihood. Fibers which can be used for the material of the present invention are, for example, synthetic staple fibers, synthetic continuous fibers, regenerated cellulose staple fibers, natural fibers such as plant fibers, wood fibers, or mixtures thereof. Commercial regenerated cellulose fibers are, for example, Rongrong, slime fibers, and lyocell. Synthetic fibers are, for example, polyester, polylactic acid, polyamide, polypropylene, polybutylene terephthalate (PBT), polyethylene (PE), polyethylene terephthalate (pET) For its copolymers, such as polyester ammonium fibers, bicomponent fibers may be used, that is, the fibers have a first polymer such as a PET center, and a second polymer such as a pe shell. Synthetic polymer fibers include polymer fibers made from natural fibers and polymers made from synthetic fibers. This paper is sized for the Chinese National Standard (CNS) A4 (210X297 mm) (Please read the precautions on the back before filling out this page)-Order -522188 A7 ~~-· B7 V. Description of the invention (6) Composite fiber. Even continuous filaments such as meltblown and spunbond fibers can be used as known capillary fibers. Such specific fibers are extremely steel and often difficult to handle, but can be tangled by means of the present invention. Even these different fiber mixtures can be used. Typical blends are 40-50% long synthetic fibers. The difference is wood pulp, but all blends are suitable. Wood pulp fibers can be chemical, mechanical, thermochemical, chemical mechanical, or chemical thermo mechanical wood pulp (CTMp). Blended with mechanical, thermo-mechanical, chemical-mechanical or chemical thermo-mechanical wood pulp fibers can provide materials with higher volume as well as improved and yielding and softness, as described in 9500585-6. According to the present invention, thermoplastic synthetic polymers and particularly semi-crystalline polymers are mainly used. Amorphous polymers can also be used. The instant heating of the natural fiber in the water needle method can be performed in many different ways. One method to provide instant temperature rise is to heat the tangled water until the fibers reach a temperature higher than Tg in the water needle method in an instant. This method is suitable when the Tg of the polymer is less than 100. This method can also be used for Tg temperatures above 100 liters. Rentong will subsequently require special equipment to generate superheated steam. Another fiber heating method is heating by infrared rays, for example, irradiating fiber webs with infrared rays or irradiating water with water needle method. Other radiant heating methods can also be used or microwave heating. Another dagger is a metal wire, such as a copper wire, which is heated by means of hot air, hot water or other media, or a combination thereof. The water needle method can begin with dry laying or wet laying of the fiber sheet. During dry forming, dry fibers are laid on the wire mesh, and the fiber web is then subjected to the water needle method. In the wet-laying method, the wet-forming foam forming sheet is manufactured by dispersing fibers in a liquid-containing or foam-containing liquid (containing foam-forming tension and water). Appropriate for this type of paper This paper size is applicable to the Chinese National Standard (CNS) M specification (21〇 × 297 mm) (Please read the precautions on the back before filling this page).,? Τ—: line 丨 A7 V 、 ^ The formation method is described in, for example, SE 9 operation 470.0. The fiber dispersion can be removed on the wire mesh and then connected with the water needle method. The water needle method can be performed using conventional equipment. (Please read the notes on the back before filling in this page) Wet-forming foam forming fiber sheet < water needle method can be performed on the line, that is, when the fiber sheet is dewatered directly on the wire net, or thin It has been dried, dried, and performed on the rolled sheet after formation. Several of these sheets can be laminated together by the water needle method. It is also possible to combine dry forming or Cheng- or foam-forming of air-laid synthetic fiber sheets such as tangled with Cheng- or foam-shaped wood-water fiber paper sheets. After the water needle method, the material is taken up by pressure and drying. The final material is then converted into a suitable format and packaged in a known manner. According to a specific embodiment of the method, the fiber dispersion system is made of a predetermined polymer fiber. The fiber dispersion system is formed on a rotating carrier such as a wire mesh. When the dispersion is formed, it is subjected to a water needle method, and water jets hit the fiber dispersion layer to entangle the fibers together. At least instantaneously, the polymer fiber is supplied with a temperature above the Tg of the polymer fiber but at the same time below its melting point. The method of heating is to produce water by the water needle method. At least during the water needle method, it is heated to a temperature higher than the Tg of the polymer fiber by any of the foregoing methods. Typical use can be set to 300-600 kWh. The pressure is 80-120 bar. Preferably, the present invention is used for polymer fibers having Tgg2 (rc), especially 20-100 ° C is suitable for 50-100X: and more preferably 50-70 ° C. Tg is preferably less than 150 ° C. Very good polymer The fiber is a polylactam (PLA) with a 50-70 (rc.) The reported value of the glass transition temperature of the polymer can vary in width. On the one hand, the glass transition occurs at a certain temperature interval rather than a specific temperature The scale applies to the Chinese National Standard (CNS) A4 specification (210X297 mm). 10 Description of the invention 'on the other hand is based on which method is used to determine the glass transition temperature. One method that can be used to determine the glass transition temperature of the present invention is j) SC ( Differential scanning calorimetry), which measures the change in enthalpy with temperature. The temperature curve for glass transition > JHL is a jump shape. This jump value is the glass transition temperature. 0 Another more sensitive method is DMA (Dynamic Mechanical Analysis) ). In this method, the storage modulus, loss modulus, and tan 5 are measured as a function of temperature (usually 1 Hz) as a function of temperature. The storage modulus of the amorphous polymer changes by a factor of ten at the glass transition temperature. Decisive power, and the loss modulus and tan (5 passes the maximum value. The concept of how much the glass transition temperature modulus changes can also be obtained using this method. The glass transition temperature of most semi-polymers is shown in a well-known manual for the industry. For the purpose of the present invention, Tg can be Taken from, Polymer Handbook J. Brandmp and ε · Η · Immergut, Publishing House, Science and Technology Publishers. Tg can also be derived by means of one of the DSC or DMA methods. The method according to the invention is particularly suitable for those with high resistance to deformation stiffness. Fiber. High flexural rigidity can be achieved by high initial modulus value or high fiber thickness. This means that particularly suitable polymer fibers are fibers with high initial modulus or extremely thick polymer fibers such as fine with high initial modulus. Fibers or coarse fibers with less insignificant or low initial modulus. In addition, fibers that are thick and have a high initial modulus can be used. The initial modulus of polymer fibers is expressed in cents of N / tax.

The concept of modulus change at glass transition temperature can also be obtained by DMA. The initial modulus value according to the present invention is the initial modulus value of the fiber at room temperature according to the present invention (refer to SS-EN ISO 5079). The fibers of the thickness can be used, that is, including microfibers, fibers having a normal thickness of about 1-2 dtex, and thick fibers having a thickness of about 6-7 dtex. According to a specific embodiment, extremely thick fibers can be tangled to form a fibrous fabric having a high volume. According to the present invention, a new material, that is, a novel non-woven fabric manufactured by the water needle method, can be obtained by the water needle method. Polymer fibers are suitable to have an initial modulus value of 20 20 Nt / taxi, Extraordinarily -50 cents Nt / taxi and the best $ 100 Nt / taxi. Polymer non-woven fabrics with very high initial modulus values can be achieved, for example 100-200 Nt / taxi Special 500-1500 Nt / taxi More special 200-750 Nt / taxi and even more special 250 -600 Nt / taxi. According to a specific embodiment, the method of the present invention can be used to make extremely strong non-woven fabrics of fibers having extremely high initial modulus values, such as aromatic polyamides and aromatic polyester fibers. Of particular interest is the ability to make non-woven fabrics having a high volume according to the present invention. With this method, non-woven fabrics having extremely coarse fibers such as 6-7 dtex can be produced and non-woven fabrics having extremely high specific volume can be provided. Thick fiber usually means 25 dtex of fiber, but with this fiber, a material with an extremely high specific volume of ^ 8 cm3 / g can be achieved according to the present invention. The volume is expressed by the thickness of the material divided by the surface weight (cubic centimeters / gram). The paper size applies the Chinese National Standard (CNS) A4 (210X297 mm). 12 522188 V. Description of the invention (10) According to the invention, a volume ratio can be achieved. Non-woven fabrics with a volume of 5-15 cubic centimeters / gram, 8-15 cubic centimeters / gram and more particularly 10-1 5 cubic centimeters / gram of non-woven fabrics produced by means of the present invention, for example, have a very high specific volume of 1,050 cubic meters. Cm / g non-fabric, this is a product with very good elasticity, this example uses 25-50 micron fibers. Such fibers are extremely difficult to tangle by other methods due to their stiffness. This material is particularly useful as a wicking layer for diapers. Kernels can also be used in a variety of other applications where high volume and high elastic properties such as wipes are required. It is particularly preferred to use semi-crystalline polymer materials by using fibers having a large diameter and / or a high modulus of elasticity. The resulting non-woven fabric has a low relationship to the stiffness of the fiber, so it can provide a non-woven fabric composed of substantially 100% polymer fibers or fiber mixtures. Additives (examples). This non-woven method is less dependent on the flexural rigidity of the fiber than the prior method, and the foregoing description clearly provides the possibility of exploring a variety of potential uses. Novel materials can be manufactured with novel properties. For example, fibers can be optimally stretched by other methods than water jets and are therefore only stiff and tangled. Suitable fibers of this type are, for example, polyester fibers and polypropylene fibers. The tensile strength of the fibers can be increased by stretching to provide novel properties to the fibers and non-woven fabrics made from the fibers. This method can be used to make such fibers, for example, by the water jet method. Fibers pre-treated in this way often fail to use the water needle method with today's methods. This paper size applies to Chinese National Standard (〇6) People 4 specifications (210 \ 297 public love) 522188 V. Description of the invention (11 (Please read the precautions on the back before filling this page) The significance of the present invention is that it has a more common use Fibers that are more rigid and / or thicker in the water needle method can be tangled to a high degree of entanglement at a reasonable energy level. In addition, fibers that have the rigidity and thickness that are commonly used in the water needle method can be entangled at a low energy level and / or Tangled to a high degree of tangling. This method allows non-woven fabrics containing extremely fine fibers to be tangled easily, thus obtaining a material with high volume and good elasticity. The additional advantage is that the material can be manufactured at a lower cost because the manufacturing cost and dimensions of synthetic fibers Relevant and decrease as the thickness of the fiber increases. Another advantage is that fibers with extremely high strength can be tangled into non-wovens with good mechanical properties, mainly high wet strength, and the high flexural rigidity of these fibers will not affect The degree of entanglement or energy consumption has a negative impact. In summary, the invention can be described as a possibility that not only expands the possibility The number of fiber types used (in terms of polymers and dimensions), and based on criteria other than limiting the flexural rigidity of the fiber, can optimize the fiber composition used. This possible precedent is used for lower energy consumption And / or lower the cost of ingredients used to improve material properties (higher volume, elasticity, tensile strength, etc.) or reduce costs. For example, non-woven fabrics can include various fiber mixtures, including non-synthetic fiber mixtures. Synthetic polymer fibers contain The higher the percentage, the greater the degree of freedom that can be used. Of course, non-woven fabrics also have a variety of different properties depending on the degree of mixing and the type of fiber. In general, the present invention provides Higher possibility.

Non-woven fabrics with high specific volume are particularly useful as wicking layers for diapers and as household wiping materials. It is clear from the following Example 1 that the tensile strength of the fiber (PL A 'fiber) is increased by 20 to 25% due to exceeding the Tg temperature in the water needle method. This provides 2ι_25% potential energy and can be used in multiple ways.

The initial modulus value is obtained in the following manner. The tensile test was performed at Blue Ling maintenance using a pulling speed of 50 mm / min and a meter length of ig millimeters. A 100 mg weight was used to pre-tension the fibers. The initial modulus is obtained by manually drawing f 'on the straight line range of the tensile test curve. The initial mode S values shown in the table are numbers to temperatures. ^ In the dry state, the fibers have a relatively high frictional force with each other. The dry strength of non-woven fabrics is strongly related to the mechanical properties of individual fibers, such as dynamics, elongation and initial modulus. It is known from Table 1 that the strength in the dry state is almost unaffected or affected to a small extent, indicating that the fiber resumes its original mechanical properties after instant heat treatment. When the tensile test is performed in water, the fibers are more likely to slide against each other, and the degree of mechanical adhesion (degree of tangling) has a greater importance on the mechanical properties of the non-woven fabric. Table 1 shows that for all tests, the tensile index is slightly higher for materials using the hot-water X-needle method. Performing a tensile test in a tonicity solution, the friction between the fibers is roughly removed, so that the degree of entanglement constitutes a major determinant of the mechanical properties of the fabric. As is clear from Table 1, when the material is subjected to the water needle method in hot water, the tensile index of PLA increases sharply by 20 to 25% and the pA increases by more than 50%. Rigidity index values are roughly unchanged (some of them increase slightly, and some decrease slightly), which shows that the type of adhesion has not changed. If the increase in tensile strength is related to the thermal bonding to each other during the heat treatment, it is clear that the stiffness index increases sharply.
