Description

Process for grafting polysaccharide degraded from cocoa shell to polymer and yarn thereof TECHNICAL FIELD

[0001] The present invention relates to a process for grafting polysaccharide degraded from cocoa shell to polymer and yarn thereof, in particular to cocoa shell agricultural waste derived from chocolate, which is degraded to form monosaccharide or polysaccharide, then polymerized to form polysaccharide, covalently bonded to high molecular substance through grafting technology, and then made into textile yarn, so as to greatly improve the reutilization rate of cocoa shell agricultural waste. BACKGROUND

[0002] Cocoa is a tropical evergreen small tree, mainly cultivated in the tropical regions of the Tropic of Cancer and the Tropic of Capricorn. After processing, the pulp and seeds (cocoa beans) are taken, and the remaining shell accounts for 80% of the whole fruit, which means that a large amount of waste needs to be disposed of. Disposing of this waste not only causes difficult problems for agricultural enterprises, but also increases the cost burden of agricultural enterprises.

[0003] Currently, the methods of burying or burning agricultural waste such as fruit shells will cause land and air pollution, and increase the cost burden of agricultural enterprises for cleaning and transporting; therefore, using cocoa shell for value-added application and related product development technology is the best option for solving the problem of cocoa shell waste disposal. TECHNICAL PROBLEM

[0004] If cocoa shell is evaluated from the perspective of textile technology, since artificial polyester fiber is made of plastic material, it is difficult to be decomposed along with plastic garbage generated in daily consumption, and eventually becomes more serious plastic waste. However, these plastic waste flows with rainwater and river water from land to sea, and no matter in the form of plastic blocks or plastic particles, the pollution of marine ecology and environment is becoming more and more serious.

[0005] Therefore, the present invention aims to solve the main problem of developing a kind of plastic with marine biological decomposition by biodegrading the waste cocoa shell after taking the cocoa pulp and seeds, decomposing the lignocellulose, polymerizing the polysaccharide, and covalently bonding the high molecular substance to make textile yarn, which not only greatly improves the reutilization rate of cocoa shell agricultural waste, but also achieves degradation effect when soaked in seawater, is a kind of plastic with marine biological decomposition, and avoids pollution of marine ecological environment. TECHNICAL SOLUTION

[0006] The present invention aims to provide a process for grafting polysaccharide degraded from cocoa shell to polymer, which comprises:

[0007] S1, preparing an anaerobic thermophilic lignin-degrading bacteria.

[0009] S3, making a cocoa shell degradation aqueous solution: taking cocoa shell powder and adding a decomposition bacteria culture solution with anaerobic thermophilic lignin-decomposing bacteria, setting the pH value of the decomposition bacteria culture solution between 4 and 8 during the process, and after a preset time, the cocoa shell powder is degraded by the anaerobic thermophilic lignin-decomposing bacteria to obtain a cocoa shell degradation aqueous solution.

[0010] S4, polymerizing the cocoa shell degradation aqueous solution into a polysaccharide while performing grafting treatment: the cocoa shell degradation aqueous solution is subjected to a centrifugal process to obtain a degraded saccharide liquid, and the saccharide liquid is set to have a sugar content between 70% and 80%, then a sorbitol and a citric acid are added to perform high-temperature melting to polymerize to obtain a polysaccharide powder; the polysaccharide powder and an N-isopropyl acrylamide (NIPAAm) are placed in a reaction container containing ethanol, and an initiator (such as dibenzoyl peroxide) is added to perform a preset reaction process, and after the reaction process is completed, a drying process is performed to obtain a polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder; finally, the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder and a high polymer are subjected to a blending process to complete the covalent bonding of the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder and the high polymer.

[0012] Further, in step S4, the high-temperature melting is set to have a temperature between 110 degrees and 130 degrees, and an atmospheric pressure between 0.01 and 0.1 MPa, and under these conditions, the polysaccharide powder is obtained by polymerization.

[0013] Further, in step S4, the initiator is dibenzoyl peroxide, and the concentration of the initiator in the ethanol is 1×10 -3 ~ 8×10 -3 mol / L.

[0016] Another object of the present application is to provide a process method for degrading cocoa shell into chitosan grafted high polymer yarn, which comprises steps S1-S4 of the process method for degrading cocoa shell into chitosan grafted high polymer, and then performing step S5 of the yarn drawing process: using a preset plastic master batch process equipment to make a plastic master batch with chitosan grafted N-isopropyl acrylamide (NIPAAm) blended high polymer, and then performing yarn drawing operation to make a textile yarn with chitosan grafted N-isopropyl acrylamide (NIPAAm) blended high polymer.

[0017] The plastic master batch with chitosan grafted N-isopropyl acrylamide (NIPAAm) blended high polymer (such as polypropylene (PP), polyester (PET), and nylon 6 (PA6)) is subjected to yarn drawing operation to make a textile yarn with chitosan grafted N-isopropyl acrylamide (NIPAAm) blended high polymer, which can then be woven into cloth, achieving a significant increase in the utilization rate of cocoa shell agricultural waste, and the textile yarn or cloth made by the present application can be soaked in seawater, achieving a degradable effect and avoiding pollution of marine ecology and environment.

[0030] For the convenience of understanding the other features and advantages of the present application and the effects achieved thereby, the features and advantages of the present application will be described in detail below with reference to the accompanying drawings, and the following embodiments further illustrate the concepts of the present application, but do not limit the scope of the present application in any way. Embodiment 1

[0031] Please refer to Figures 1 to 8, the present application discloses a process for degrading cocoa shell into polysaccharide grafted onto high molecular weight yarns. First, as shown in Figure 7, the process for degrading cocoa shell into polysaccharide grafted onto high molecular weight yarns includes the following steps:

[0032] Step S1: preparing an anaerobic thermophilic lignin-decomposing bacteria; selecting an anaerobic thermophilic lignin-decomposing bacteria to culture the strain in an anaerobic manner. For example, during the anaerobic culture process, sodium sulfide (Na2S) is added as a reducing agent to maintain the anaerobic environment in the culture medium; in addition, the prepared culture medium under normal conditions is heated and boiled for 5 to 15 minutes, and at the same time, nitrogen gas (N2) is exposed to the culture medium using a gas station to remove dissolved oxygen in the culture medium, and then the culture medium is passed through a mixture of nitrogen gas (N2) and carbon dioxide (CO2) gas, and the anaerobic thermophilic lignin-decomposing bacteria are added to the culture medium after being exposed to nitrogen gas several times to maintain the optimal anaerobic state of the anaerobic culture. During the anaerobic culture process, glucose is used as the carbon source, the temperature is set to about 40 to 70 degrees, and the pH value is between 5 and 8.

[0033] Step S2: preparing a cocoa shell powder; first reducing the water content of the cocoa shell to below 15%, then drying the cocoa shell, setting the drying temperature to 120 degrees, and setting the drying time to 10 to 24 hours to reduce the water content of the cocoa shell to below 0.5%, and then crushing the cocoa shell in multiple stages to 8000 mesh or more to obtain the cocoa shell powder, and the particle size of the cocoa shell powder is about 1 micron or finer.

[0034] Step S3: preparing a cocoa shell degradation aqueous solution; taking the cocoa shell powder and adding a decomposition bacteria culture solution with anaerobic thermophilic lignin-decomposing bacteria, and setting the pH value of the decomposition bacteria culture solution to between 4 and 8 during the process, and after a predetermined time (e.g., 5 to 8 days), the anaerobic thermophilic lignin-decomposing bacteria degrade the cocoa shell powder to obtain the cocoa shell degradation aqueous solution.

[0035] In step S3, the weight ratio of the cocoa shell powder to the decomposition bacteria culture solution is between 1:5 and 1:10.

[0036] Step S4: The cocoa shell degradation aqueous solution is polymerized into polysaccharide while being subjected to grafting treatment; the cocoa shell degradation aqueous solution is subjected to a centrifugal process to obtain a degraded polysaccharide liquid, and the polysaccharide liquid is controlled to have a sugar content of 70% to 80%, and then 5% to 20% sorbitol and 0.5% to 10% citric acid are added to be subjected to high-temperature melting to be polymerized into polysaccharide powder, the polysaccharide powder has a polysaccharide molecular formula as shown in FIG. 1; the polysaccharide powder and N-isopropyl acrylamide (NIPAAm) are placed in a reaction container containing ethanol, N-isopropyl acrylamide (NIPAAm) is used as a grafting agent, the molecular structure of the polysaccharide and N-isopropyl acrylamide (NIPAAm) is shown in FIG. 4, and the molecular formula of N-isopropyl acrylamide (NIPAAm) is shown in FIG. 2, an initiator is further added to be subjected to a preset reaction process, and then a drying process is performed after the reaction process is completed to obtain polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder, and the reaction structure of the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) is shown in FIG. 5; finally, the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder is subjected to a blending process with a high polymer to make the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder covalently bonded with the high polymer, and a polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended high polymer is obtained, as shown in FIG. 6, which is a schematic diagram of the grafting structure of the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder covalently bonded with a high polymer (such as polypropylene (PP)) powder.

[0037] In the step S4, the cocoa shell degradation aqueous solution is subjected to high-speed centrifugation at 8000 to 10000 RPM to obtain a degraded polysaccharide liquid.

[0038] In the step S4, the high-temperature melting is set to have a temperature of 110 to 130 degrees and an atmospheric pressure of 0.01 to 0.1 MPa, and the polysaccharide powder is obtained by polymerization under the conditions.

[0039] In the step S4, the N-isopropyl acrylamide (NIPAAm) used as the grafting agent has a concentration of 0.1 to 0.8 mol / L in ethanol.

[0040] In the step S4, the initiator is dibenzoyl peroxide, also known as benzoyl peroxide, commonly known as initiator (BPO), which is an organic compound, and its molecular structure is shown in FIG. 3; and the initiator has a concentration of 1×10 -3 to 8×10 -3 mol / L in ethanol.

[0041] In the step S4, during the reaction, nitrogen is continuously introduced, the reaction time is set to 1-8 hours, and the reaction temperature is controlled to be between 70-90 degrees.

[0042] In the step S4, the high molecular material can be plastic, such as PET (polyethylene terephthalate), PA6 (polyamide (nylon)), PP (polypropylene), PE (polyethylene), ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), PVDF (polyvinylidene fluoride), PS (polystyrene), PES (polyether sulfone), PVC (polyvinyl chloride), PAN (polyacrylonitrile), PA6 (nylon 6), and other high molecular materials of plastic.

[0043] In the step S4, the blending process is to mix the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder and the high molecular material through a default plastic master batch process device to form a grafting bond, thereby achieving the process of degrading the cocoa shell to the high molecular material grafted with polysaccharide, and finally a plastic master batch with polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended high molecular material can be prepared.

[0044] The plastic master batch process device has a double-screw air extraction mechanism, and the double-screw air extraction mechanism can be in a vacuum state. For example, the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder and the polypropylene (PP) powder of the high molecular material are first added to the double-screw air extraction mechanism, and high-speed stirring is performed at a speed of 1000-2000 RPM, and the weight ratio of the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder to the polypropylene (PP) powder is between 1:5 and 1:10. Then, the plastic master batch process device processes the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder and the polypropylene (PP) powder into a high molecular melting state. In the melting state, the polysaccharide grafted N-isopropyl acrylamide (NIPAAm) powder and the polypropylene (PP) powder (i.e. high molecular material) are mixed and grafted, and the grafting structure is shown in FIG. 6. Finally, a plastic master batch with polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended high molecular material can be prepared, and the blending amount of the grafting agent (i.e. N-isopropyl acrylamide (NIPAAm)) is between 0.1-1% relative to the weight percentage concentration of the high molecular material.

[0045] Therefore, the process method of degrading cocoa shell into polysaccharide grafted onto high polymer, the main technical features are as follows: cocoa shell, which is an agricultural waste derived from the chocolate manufacturing process, is reused, mainly by using anaerobic thermophilic lignin-decomposing bacteria to degrade the cocoa shell into monosaccharide or polysaccharide, then adding sorbitol and citric acid for high-temperature melting to polymerize into polysaccharide, finally adding N-isopropyl acrylamide (NIPAAm) and grafting technology to make it covalently bonded to high polymer, thus completing the process of degrading cocoa shell into polysaccharide grafted onto high polymer; in this way, a plastic master batch of polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended high polymer (such as polypropylene PP) can be further prepared; the cocoa shell agricultural waste reuse rate is greatly improved, and the high polymer or its master batch prepared by the application can be soaked in seawater, which indeed has a degradable effect and avoids polluting the marine ecology and environment.

[0046] The application further discloses a process method of cocoa shell degraded into polysaccharide grafted onto high polymer yarn, which is shown in FIG. 8 and comprises steps S1-S4 of the process method of degrading cocoa shell into polysaccharide grafted onto high polymer, and further comprises step S5 of drawing yarn: a plastic master batch process device is used to prepare a plastic master batch of polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended high polymer, and then the plastic master batch is subjected to drawing yarn operation to prepare a textile yarn of polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended high polymer, which can be woven into cloth, so that the cocoa shell agricultural waste reuse rate is greatly improved, and the textile yarn or cloth prepared by the application can be soaked in seawater, which indeed has a degradable effect and avoids polluting the marine ecology and environment.

[0047] As shown in Table 1, the cloth made of textile yarn of polysaccharide grafted N-isopropyl acrylamide (NIPAAm) blended polyester (PET) is tested for marine seawater degradation, and the results show that the weight loss of the cloth is nearly 2% or more, which indeed has a degradable effect.
