Description

201005143 IX. Description of the invention: [Technical field to which the invention pertains] - The present invention relates to a gradual color fiber and a method for producing the same, in particular, dyeing of the original dyeing method in a thermoplastic fiber, by controlling at least the condition of the filament (4) The gradual color fiber obtained and a method for producing the same. Turn to [previous technology]

It is more changeable and used in the past. However, the dyeing of dyeing and bath dyeing is to make the color of fiber and fabric more vivid printing or bath dyeing to achieve the gradual color effect method to produce a lot of waste water, leading to environmental protection problems. Chinese patent CN2564602Y reveals a gradual dyeing device technology. Expose the Le-spray dyeing method to achieve the gradual color fiber = special. However, its raw money is slow, and the dyeing is poor. In addition, the French patent FR 2682m proposes another technique to achieve the purpose of gradual layering. The technique is to fix the dyed material on the support. When the support is gradually invaded, the dyeing time is different by different heights. Used to achieve the gradual effect. However, this method relies on the bath-based method, which will cause a large amount of waste water to be a major damage. It is also disclosed in the same 'Canadian Patent CA 22422U, which also controls the dyeing time of fabrics of different heights through a gradual bath dyeing solution to achieve a gradual color effect. However, this method also uses the dyeing method of Luo dyeing, which also produces a large amount of waste water. Therefore, how to achieve the production of gradual color fibers in the case of rapid production and non-emission of a large amount of sewage will be an important issue for the gradual color fiber and its manufacturing method.曰5 201005143 [Summary of the Invention] In the loss of the birth axis, to avoid the existence of the missing, her purpose is to fiber, and to seize the eve of the day - the composition of the original dyeing, the water / the water in the next month to reach the gradient The output of colored fibers. m manufacturing method, A special, - a gradual color fiber and part of the original _ color, and at least = = 1; hot 3 fiber 'which contains more than one component color fiber, and use The fibers are made into a fabric. In the raw nr two to the group, the fiber and the two or more parts of the composite fiber, a content is changed to obtain a gradation color fiber having a color change. , > A raw material in the production of LU two to::: =: = composite fiber ': at least one Hyun _ machine output continuously changes, and the second gradual =, The composition is made of injection resin. 201005143 The polymer of the thermoplastic resin is selected from the group consisting of polyheteroester, poly-copolymer, and polystyrene resin. One of a mixture of Wei ammonia filaments, polypropylene _, polypropylene copolymer, polyethylene resin, polyethylene garnish, and a mixture of the above polymers. When the field thermoplastic fiber is dyed with at least one dye or pigment, the color of the color of the color will change. If the color of the color is changed by at least 1, the gradual color fiber can be obtained. The method for controlling the change of the colorant content is: ❿ ❹ (1) Constantly and professionally changing at least one meter to measure the colorant content. There is a small amount of m-melting (4) applied to county dyeing, and the amount of material discharged from the forest is changed periodically and periodically, and 贞 periodically changes. It is a combination of two ways: or a combination of the above two methods. j 'When the heat can be aged at least - _ material, lai for the original dye τ, cut, quasi-fineness (or denier) to change the color of the occupational dimension, and continuously change the fiber fineness, you can get $ left The method of change by the company is: _ color _ ° its control fiber fineness has a new lion to change the total output of the county pressure material (at least - the amount of discharge of the secret pressure machine is constantly changing). (The use of the extension method of the peach, the change of the fake money, the change of the extension or the combination of the two methods of the above (3). In summary, when the thermoplastic is dyed, the following at least - Silk condition, part of the original dimension and its fabric: 7 pieces to the gradual color of the fiber 7 201005143 () constantly and periodically change at least one meter count (2) constantly and periodically change - age = (The total discharge amount can be changed or changed continuously) ^The discharge of the machine . Change the fineness of the fiber 3 in any other way of extension, the method of false and continually and periodically, and the way The gradation effect is also different, the biggest is no money, the color concentration is gradually changing and the hue does not have _ change or

There are two ways to have a significant gradation change. The detailed description of the method: The following two kinds - one change the county - the amount of 11 metering color content: when only the use of the color content of the denier 'control continuously changes the metering amount of color t: then, get Gradient-colored fibers with varying color concentrations. When two metering colorant contents are used, the control continuously changes at least one metering coloring material s!_贞] to the grading color fiber of the hue change. (2) Constantly changing the discharge amount of at least one of the melt extruders. · When the thermoplasticity is made, if it has a part, at least, it is at least a kind of secret, and the surface is dyed on the original day. The larger the discharge amount of the 融成部健融压机, the more the color is on the bed stomach. The part with the original dyeing is the smaller the discharge amount of the melter. The lighter the color, the more the output is continuously changed. Then, a gradation color fiber having a gradual change in color density can be obtained. When at least two components of the composite thermoplastic fiber are colored in the same color (the colorant includes at least one dye, pigment) but the concentration of at least one dye or pigment is different, the color concentration is high. The larger the discharge amount of the part of the melt extruder, the darker the color, and the lighter the color. However, in this way, the color density is 8 201005143 ι has a gradual change but the range of depth change is small. -, ################################################################################################### The larger the silk pressure field is, the closer the hue of the fiber is to the original dyed hue of the composition, and the closer the color is to the original dyed hue of the composition of the crucible; when the proportion of each component is continuously changed, the fiber is now colored. Will continue to change, through the composition of the φ = component, you can get the color of her = sex fiber (2) extension mode, health mode change _ fineness: when the thermoplastic color, at least one component If at least one dye or pigment is used for the original 2 fiber or fiber, the smaller the stretching ratio, the larger the 细 细 φ 曰 or the fiber will be, the higher the color density of the fiber, when the number of fibers is combined , Γ, 々 'the greater the extension ratio', then the fiber fineness (refers to the fiber denier rate, the lower the color density of the fiber at 22:2. By continuously changing the extension, passing to the gradient with the gradual change of color concentration Color age. In the dyeing mode, the weight percentage of the in part of the component ranges from read % to delete. The control alone is based on the fact that the present invention discloses the original dyed gradual color fiber, at least -β, cycle Sexually changing at least one meter to measure the colorant content, or to change the machine's discharge amount continuously and periodically, or to change continuously and in a ship's manner. Fiber fineness, in order to obtain the application of the gradual-color composite fiber-dyed biochemical fiber for the original dyeing, at least one of the 9 201005143 components in the production of the fiber is subjected to the original dyeing, and the control is carried out to the spinning condition. In order to obtain the gradual color fiber and the surface material, the production of the gradual color fiber is achieved in the case that the rapid production material discharges a large amount of sewage. [Embodiment] The details and technical description of the syllabus are now given by way of examples. It is to be understood that the examples are for illustrative purposes only and are not to be construed as limiting the implementation of the invention. The amount of discharge or the original dyed fiber whose fiber fineness is changed by the method of one-foot extension and false twisting, and the dyeing is carried out, and the melt-extruding machine carries out at least one dye and pigment, and then at least one of the following modes. Obtaining the gradation of the fiber: the amount of the toner from 1 to i is reduced by at least one of the original dyeing contents; the interstitial = second secret relationship is gradually changed (as shown in Figure 1, the horizontal axis system Gradually change the amount of f-measured pigment); or measure the color of the toner with a non-linear relationship. The axis is the spinning time 'the vertical axis is the meter'). The effect of the application is as follows. In the case of the fiber false twisting of the embodiment 10, the stretching ratio is continuously changed, and the degree of change is changed, and the color is rich (as shown in Fig. 3). The fiber fineness can be linear. Gradually change, no, the axis is the spinning time, the vertical axis relationship gradually changes (such as old age - dimension), or according to non-dimensional fineness). If the sleeve is the spinning time and the vertical axis is the fiber (2) single-component spinning, the discharge amount of the squeezing extruder will gradually change with the linear relationship 201005143 (as shown in Figure 5, the horizontal axis is Spinning time, the vertical axis is the discharge amount); or gradually change in a nonlinear relationship (as shown in Fig. 6, the horizontal axis is the spinning time, and the vertical axis is the discharge amount). (4) At least one of the components of the melt extruder discharge gradually changes in a linear relationship during the composite spinning (as shown in Fig. 5); or gradually changes in a nonlinear relationship (as shown in Fig. 6). As in Examples 2, 3, 4, 5, 6. (5) The combination of at least two of the above changes.

Thereby, the at least one meter metering color content is continuously changed by the control, or the at least one melt extruder discharge amount is continuously changed, or the fiber fineness is changed in any other extension manner, false twisting manner, and the original dyed fiber , you can get the gradual color of the fiber. Wherein, when any component is dyed by the original dyeing method, the total colorant content of the component is in the weight percentage range of the component, 0.01% to 10%.
