Description of the Invention: [Technical Field] The present invention relates to a nonwoven fabric and a method of manufacturing the same, and in particular to a straight-spun nonwoven fabric and a method of manufacturing the same. [Prior Art] Non-woven fabric is an application of rayon, and its process combines technologies and principles such as plastics, chemicals, papermaking, and textiles. The application of such rayon is called "non-woven" because it is not made by conventional weaving or knitting, etc. Non-woven fabric has the characteristics of low manufacturing cost, moisture absorption, dustproofness and antistatic property, so it is widely used. For all industries such as agriculture, construction, people's livelihood, industry, medical music, and automobile industry, non-woven fabrics are used as materials for filtering, blocking, and moisture absorption. For example, in the case of straight-spun non-woven fabrics, the manufacturing process is to first polymerize The material is spun into filaments, and the continuous filaments are passed through to form a straight-spun nonwoven fabric. In general, high-strength materials with hot melt properties and good filament properties can be applied to the production of straight-woven non-woven fabrics, so the straight application range is quite wide. In order to increase the mechanical strength of the direct-spun non-woven fabric, the fibers are more closely stacked to obtain a flat finished product, and the surface is welded to the surface by means of heating and rolling to make the fiber ^3,,,. ^ However, in the process of welding the surface of the fiber, the problem of bonding between the two dimensions will occur, and the flatness of some mechanical (four) woven fabrics will be poor. This raw material of the shell is not good after spinning. Dissolved in 200829430 095Q050 22066twf.doc / n = 'Ly〇eell raw materials' material is suitable for this process - although the lack of powder way to strengthen this ^ ^ π, and the stack is strong, the department will increase the process steps And the raw material type weaving r cannot be made in a simple system. [Inventive content] The winter invention provides a non-woven fabric, which has a high-strength manufacturing method of making a woven fabric, and the remaining surface of the coarse wheel is smooth and the second surface is relatively small. The woven fabric is a straight-spun non-woven fabric. The non-woven fabric is composed of -fiber and non-woven fabric having -$i缄, f. wherein the cellulose fibers are bonded to each other. The fiber 'face' sub- and non-woven fabric surface _卩= The younger brother of weaving - the surface is thick The roughness is lower than its roughness. X 'So the surface of the younger one is smoother and the second surface is more like the example in the embodiment, the roughness of the first surface (four) to 80 =. _ to 2 〇 and the coarse round 12 For example, it is between 5 and 5 〇, and the roughness of the surface of the above-mentioned brother is, for example, _, and the thick chain & for example, is in the embodiment of 30 (four) to 300 ★ months, the first surface mentioned above Droplet diffusion 6 200829430 095Q050 22066twf. doc/π Capability of droplet diffusion on the second surface, wherein the droplet diffusion capacity of the first surface is, for example, between the hired mm2/6Qsee; and the liquid on the second surface The droplet diffusion ability is, for example, 5 to 10 mm 2 / 60 sec. The present invention further proposes a method for producing a direct-spun nonwoven fabric to produce a straight-spun nonwoven fabric. The steps of the method include providing a first The spinning solution is sub-injected into a spinning-spinning step, wherein the spinning solution comprises a solvent and a fibrous material dissolved in the solvent. In essence, the solvent comprises N-methyl-coded oxygen, (N_methylmorPholine-N-〇 Xide, NMMO) 'And the fiber material includes bismuth, quasi-prime. The process is to make the spinning solution solidify on the ice layer into fibers which are stacked on each other to form a cellulose non-woven fabric. It is worth noting that the fibers are bonded to each other before being completely cured, and the finished non-woven fabric has a first The first surface of the surface and the second surface have a lower roughness than the roughness of the second surface, so that the first surface is smoother and the surface of the second surface is thicker. In one embodiment of the invention, the spinning is as described above. The silk liquid is, for example, solidified on the ice layer sprinkled with crushed ice pieces into fibers stacked on each other, or, for example, on the ice layer which is formed into a layer of frost to be solidified into fibers stacked on each other. In an embodiment of the invention, the spinning step is, for example, to provide a spinning device and to incorporate the spinning solution into the spinning device. Next, a curing device having an ice layer is provided at a position relative to the spinning device. Subsequently, the spinning solution is ejected from the spinning device onto the curing device to solidify the spinning solution on the ice layer into fibers stacked on each other. In an embodiment of the present invention, a conveyor belt is further disposed on the curing device, and an ice layer such as a crucible is placed on the conveyor belt to superimpose the fiber stack 200829430 22066twfdoc/n on the surface of the mesh belt. And rotate the fibers stacked on each other. In the first aspect of the present invention, the distance between the above is, for example, 30 cm~! meter. U-coating - mentioning that the spinning pressure of the simple liquid self-spinning device sprayed out on the snagging through the squeegee is, for example, between 2 rings and the fiber-mouth-coating-setting, in the spinning step After that, it also includes the Jingjijing bonding to each other in the state of full/rotation, so that there is a degree of editing. The present invention == should == wide r can make the quality of the non-woven fabric more suitable for the above and other objects of the present invention, the ship = the preferred embodiment, and with the drawing '42 Memories] Mountain = a method for manufacturing a straight-spun non-woven fabric with better mechanical strength - a kind of straight-non-woven fabric, the flow of which is shown in Fig. 2 and the detailed description of each step is as follows. Please refer to Figure 1A 'First' for step 11〇, providing 'the spinning solution including the solvent and the fiber in the solvent.

In a more delicate case, the flow of the spinning step is, for example, as depicted in Fig. 1B: first, the spinning device is provided (step 122), and the spinning solution is placed in the spinning booth. Next, a fixing device having an ice layer is provided with respect to the spinning device (step 124). Subsequently, the spinning solution is ejected from the spinning device to the curing garment (step 126)' to solidify the spinning solution on the ice layer into a scale which is stacked on each other. The ice layer on the curing device is, for example, an ice layer sprinkled with crushed ice or, for example, an ice layer formed into a layer of frost. • In the spinning step, 1 may include placing a conveyor belt on the curing device, and the ice layer is placed on the conveyor belt, for example, so that the fibers are stacked on the surface of the conveyor belt and transported to each other. fiber. Actually, the distance between the spinning device and the curing device is, for example, 30 cm to 1 m. Further, the spinning pressure for ejecting the spinning solution from the spinning device to the curing device is, for example, 25 psi to 2000 pSi. Further, after the spinning step, a drying step (step 128) is further included, and the nonwoven fabric is dried for storage and use. It is worth noting that the rate of solidification of the fibers stacked on each other on the ice layer is relatively high, so that the fibers will stick to each other and diffuse slightly before the film is completely cured. Stacked more closely. Thus, the mechanical strength and wear resistance of the stacked fibers in the direction of the vertical ice layer can be greatly increased. In other words, the direct-spun type non-woven fabric of the present invention has strong mechanical strength and wear resistance. ^: It is bonded to each other before the second. Therefore, there is no need to add a cross-linking agent & material. Therefore, the straightness of the present invention
