For example, on the trademark cloth, the anti-counterfeiting inks of the light are shouted, and the anti-counterfeiting fibers are mainly in special light. Age will show different _ color, the role of anti-counterfeiting and 'counterfeit ink, is made of county powder plus printing ink towel, to be presented under the light of special light; 5; with the same color Anti-counterfeiting function; however, this kind of miscellaneous is easy for the reader to achieve, and can not really achieve the absolute anti-counterfeiting function. There are also other anti-counterfeiting technologies in Fufang, such as FRID anti-counterfeiting, laser-aged pseudo-counterfeiting, etc., where 'cafe scales are based on pseudo-tear, mainly _ total, read line communication party = pass-through bait, then through ID _ To distinguish and track, put the coffee ^cheng on the product or put it in Zhangzhong, and the second is judged by the machine to buy it. The laser standard iron anti-counterfeiting technology mainly uses the recording generator to generate high. The co-axial beam of energy causes the surface __镰 to even vaporize, forming a graphic mark. However, using the anti-counterfeiting technology such as > ^ Yuntong D laser standard iron, it is still impossible to achieve absolute anti-counterfeiting in the product, and there are still shortcomings that are easy to counterfeit. SUMMARY OF THE INVENTION The present invention provides a melt-spun core sheath for producing a cross-sectional composite fiber having a high-efficiency anti-counterfeiting function and a method for producing the same. The melt-spun core-sheath type cross-section composite iron dimension is produced by the melt-spinning spinning technique, that is, the main object of the present invention is to provide a method for manufacturing the same, and two kinds of high-molecular polymer raw materials 5 200815634 The core-sheath composite fiber with know-how and fixed-section structure is woven into the trademark cloth substrate by weaving, and then processed with special coating and terminal treatment technology to make it easy to identify, so as to achieve high-efficiency anti-counterfeit trademark cloth. Claim. To achieve this, the present invention employs the following technical means. The melt-spun core-sheath type cross-section composite fiber of the present invention and a manufacturing method thereof are characterized in that a polymer polymer is used as a core material to form a core material (four), and another polymer is used as a pin component in the fiber. The main raw material is used to make the core-sheath type cross-section gene simulation anti-counterfeiting fiber. The above embodiments of the invention include the use of a molten composite spinning apparatus. First, the two core polymer materials of the core component and the sheath component are placed in respective melt presses, and then melted by respective melters, extruded and confluent, and then flowed through the composite spinning box and the spinning wire. Plate, spit out each of the core-sheathed full-direction filaments with two polymer compatibility (Sinus r|ente (| yam, F〇Y), forming a fiber strength greater than 2 g / Danny, fiber elongation It is a F〇Y anti-counterfeiting fiber of 20%~5〇%. The above anti-counterfeit fiber is a full-directional fiber ^^^, no other processing is required, the fiber cross-section is not deformed and the spinning speed is fast and no other processing is required. The anti-counterfeiting fiber has uniqueness and technical difficulty, and is not easy to be counterfeited. The commercial fabric substrate is introduced into the anti-counterfeiting fiber by using a weaving combination; the trademark cloth is easily recognized by light inspection, and then cross-sectional inspection, with high efficiency multiple identification and anti-counterfeiting The above objects, features and advantages of the present invention will become more apparent from the aspects of the preferred embodiments illustrated in the <RTI Melting of core-sheath type cross-section composite fiber Schematic diagram of the composite spinning apparatus 40. The second drawing is an enlarged cross-sectional view of the fiber of the melt-spun core-sheath type cross-section composite fiber 3 of the present invention. The specific pattern of the section of the fiber 30 is shown in the figure. 1 is a flow chart showing the manufacture of the melt-spun core-sheath type cross-section composite fiber 30 of the present invention. In the first figure, the manufacturing step includes placing a core component 10 and a sheath component 20, respectively. A molten composite spinning apparatus 40 is separately melted and recombined, and the core spinning type full-direction yarn containing the above two polymers can be prepared through the composite spinning box 43 and the spinneret 44 in the apparatus. Orientyam^FOY), that is, the melt-spun core-sheath type cross-section composite fiber 30 of the present invention. Referring to the first figure, in the above embodiment, the core component 10 used is composed of a raw material to form a fiber. Polymer-based, such as polyethylene terephthalate (PET), nylon 0 (nylon 6, PA6), high density polyethylene (HDPE), polypropylene (PP) , nylon 66 (nylon 66, PA66) or poly Preferably, polyethylene napMialate (PEN) is used. In the above embodiment, the sheath component 20 used is made of polyethylene terephthalate (PET) or nylon. 6 (nylon 6, PA6), high density polyethylene (HOPE), polypropylene (PP), nylon 66 (nylon 66, PA66). It is to be noted that the manufacturing method of the present invention uses polyethylene terephthalate I (PET) as the main constituent material of the sheath component 20 in the core-sheath type cross-section composite fiber. The sheath component composed of the above polyethylene terephthalate raw material has a molecular weight of about 10,000 to 40,000, a melting point of about 250 ° C or more, an acid value of less than 2, and a viscosity of about 20, 〇〇〇~ Between 50,000 poises (P〇ise). It is also worth noting that the core component ω used in the method of the present invention accounts for about 20% to 50% by weight, and the sheath component 202 has a weight percentage ranging from about 50% to 80%. It can be set according to the needs of the final product. After separately preparing and selecting the above-mentioned core component 1〇 and the sheath component 2〇, the two different kinds of 7200815634 parts of raw materials are respectively placed in the molten composite spinning box 43 and the respective groove grooves are similar to each other. In the respective melting machines 41a, 41b, for example, as shown in the first figure, the core component 1〇 is dropped from the groove to the melter 41a, and the sheath component 2 is dropped from the groove 42b to the melted machine. . Next, the core component 10 and the sheath component 2 are respectively secreted by their respective occupations, and they are secreted at a high temperature, and the ___, _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Full-direction silk (_, its fiber fineness is about 3 () ~ Danny, fiber 2 degrees 420% 4G% 'and fiber thief can be greater than about 3 grams / Danny; from the fiber, the face, early The silk fiber scale type riding surface. Because of the cross-fibre, the fiber can be subjected to textile processing such as knitting or woven without causing fiber breakage. In the enlarged cross-sectional view of the fiber, the core component 1〇 is formed by coating the above-mentioned bismuth-shaped pattern, which is an embodiment of the composite fiber 30 produced by the present invention. The first-figure_fusion composite spinning equipment, if necessary, different spinnerets 44' can also be made into a cross-section that can be displayed as a variety of different characters, numbers, patterns, patterns of composite age 30, and not only implementation The text shown in the above. The above-mentioned hairpin Na Rong '__ lie _ π, private axis _ f〇y, = need other heart, she is increasing,胄 standard fabric substrate, = when the combination is introduced into the composite fiber 3G, the trademark fabric is easily identifiable by light inspection: or the cross-sectional view of the cross-domain dimension is used to identify the unique characteristics of the composite fiber (4). Multi-identification and anti-counterfeiting, not easy to be counterfeited. ^The above-mentioned 'this side can be _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The invention is based on the short form (4).
