Description

The present invention relates to a new yarn containing coffee koji.

  In recent years, the design and research and manufacture of a kind of functional textiles that can control the amount of heat according to changes in skin temperature have attracted more and more attention. The large-scale efforts being pursued in this field are comparable to the research being conducted in electronics, solar energy devices and architecture. However, there are very few successful applications and these applications are still under study.

  As is generally known, various materials such as textiles, apparel and other apparel can enhance performance characteristics associated with the material through processing. These performances and characteristics include, for example, deodorization, humidity control, UV protection, and / or prevention of external factors.

  Certain materials have certain inherent performance characteristics without being treated with chemical formulations or additives. For example, a garment made of a material that has not been treated like lycra has elastic properties. However, the lycra material does not have other properties such as deodorization or UV protection. In addition, garments made of untreated materials have limitations on physical properties (for example, woven patterns, touch, durability, etc.) regarding the untreated materials. Moreover, the performance characteristics of these materials are usually limited, and the performance of the materials cannot be sufficiently enhanced.

  However, after the chemical reagent is operated, the chemical reagent volatilizes well and the required properties must be provided by the continuous addition of the chemical reagent during the entire manufacturing process of the fabric. For example, chemical reagents can volatilize when the treated fabric is laundered or exposed to the external natural environment.

  This is a kind of high-performance fabric that people are expected to have, for example, woven and durable physical properties, provide better performance characteristics, and still retain these performance characteristics after repeated use. Want to manufacture. Such high performance fabrics can be manufactured by processing the yarns or fibers before they are used to produce the necessary materials.

  It has already been tried to deposit solid particles (eg activated carbon) on the yarn before producing the fabric. Activated carbon is a particulate material having a different shape and size, and the shape and size are determined by the method for producing the activated carbon. The activated carbon surface may also cover holes of different shapes and sizes, the size and shape depending on how they are manufactured. These holes give the activated carbon the property of deodorization.

  One method is to sandwich an activated carbon layer between two layers of fabric. However, a fabric having a deodorizing function obtained by applying such a technique is very heavy and is relatively troublesome to wear. Another known method is to incorporate activated carbon into the covering layer covered with the yarn. However, such methods change the physical properties of the yarn.

  Human activities may generate unpleasant odors in the environment, and the nature of these gases is extremely high due to differences in the physical state and chemical properties of gas particles or the cause of formation (biodegradation, chemicals, smoking, etc.) Are largely distinguished. In addition, these unpleasant odors occur in our daily living spaces and environments such as bathrooms, kitchens, garbage, and closed environments (bars) filled with smoke. This has led people to develop a number of methods to prevent odors that are unpleasant for this type of person.

  Although coffee candy has been seen as garbage after producing coffee beverages, the present invention provides an environmental protection method for recycling coffee candy by using the coffee candy for yarn preparation. And a material containing coffee cake that contains carbonized particles and has already removed organic components. Carbonized particles can be prepared using a carbonization method for the material containing the coffee grounds. Further, these yarns can be used for producing woven fabrics and clothes. In addition, in one Example, the material containing this coffee koji has a scent of coffee.

  In one embodiment, the yarn containing the coffee grounds of the present invention comprises: (a) providing a material containing coffee grounds; (b) preparing a masterbatch that mixes the material with polymeric polymer particles; and (c ) Preparing the masterbatch into a yarn, and making use of a method for preparing a yarn containing coffee koji. The material used in the present invention is roasted coffee cake, microencapsulated roasted coffee cake, microencapsulated coffee essential oil, or organic compound having a fragrance extracted from microencapsulated coffee cake. Can do. In a preferred embodiment, the coffee grounds are ground coffee beans or coffee grounds. The aforementioned materials further include carbonized particles, which are prepared from carbonized coffee cake particles, carbonized palm particles or carbonized bamboo and bamboo particles. In addition, the process for preparing carbonized coffee particles requires sieving, and organic components are removed from the sieved mixture, and then carbonized particles are obtained from the mixture containing no organic components. The polymer particles used in the present invention are selected from polypropylene, nylon or polyester.

  The present invention further provides a yarn having a coffee scent, comprising a yarn containing coffee candy prepared by the above method and a material having a coffee scent. Of these materials, carbonized particles can be prepared using a carbonization method. Further, these yarns can be used for producing woven fabrics and clothes.

  The present invention further provides a woven fabric containing the above yarn. The fabric is a plain fabric or a knitted fabric.

Example 1: Preparation of material containing coffee candy and carbonized coffee particles 1. Preparation of material containing coffee candy The technical term "material containing coffee candy" includes roasted coffee candy, microencapsulation Including, but not limited to, a scented organic compound extracted from the coffee brewed coffee, microencapsulated coffee essential oil, or microencapsulated coffee mash. The coffee grinder may be manufactured after roasted coffee beans or coffee grinds ground in a coffee shop. Coffee essential oil can be extracted from the coffee beans. Finally, roasted coffee gruel or coffee essential oil is enclosed in microcapsules.

2. Sifting of the material containing coffee mash After the coffee beans waste material is washed with clean tap water, it is first dried and polished to particles of 20-100 μm in size, and the ground coffee beans are directly sieved . In addition, after drying and polishing the coffee cake, the polished mixture can be sieved. The resulting mixture can be sieved to ultrafine particles of different sizes of 80-100 μm.
The “mixture” described in the present invention is also a material containing coffee mash at the same time, among which the ingredients contained in the coffee mash include water, minerals, carbohydrates, sugars, organic acids, proteins, lipids, volatiles Organic components and non-organic components such as substances, pectin and lignin are included, and this is not limited.

3. Removal of organic components in the mixture after sieving The mixture obtained by the above method (waste coffee beans) contains organic components and non-organic components. In a preferred embodiment of the present invention, the organic components of the mixture are removed from the mixture after sieving with an organic solvent so that the material containing coffee mash is not bound. The fatty component is removed with ether in a Soxhlet extractor and removed, and the removal temperature is controlled to 60 ° C. or lower. Inert gas is blown during all subsequent operations to avoid contact with air as much as possible, and distillation is required before all solvents are used. The lipid component is treated with acetone, and the lipid-soluble component dissolved in acetone is refluxed in an ethanolated potassium hydroxide solution containing 5% or more to generate a saponification reaction, thereby removing the lipid. After the saponification reaction solution is oxidized with 0.1N hydrochloric acid, fatty acids are extracted with ethers. After removing the fatty acid, the aqueous solution containing the water-soluble component is concentrated and dried under reduced pressure conditions, and then glycerin is extracted and removed with anhydrous alcohol. Further, in addition to the method of taking out and removing the organic components of the mixture with an organic solvent, the organic components of the mixture can be removed with equipment that is supercritical or subcritical of carbon dioxide.

4. Preparation of carbonized particles The mixture obtained from the second step or the second and third steps is carbonized by an existing carbonization method. For example, a coffee mixture is heated in a fixed bed reactor under oxygen-deficient conditions to generate a pyrolysis reaction and ultimately convert to the product we desire. The pyrolysis reaction includes carbonization, vaporization and activated carbon processing, and the product of pyrolysis is activated carbon. The carbonization of coffee materials is generally completed with the addition of chemical reagents such as zinc chloride, magnesium chloride, calcium chloride or phosphoric acid. Carbide material is processed in a melting furnace at 800-1000 ° C under conditions of blowing oxygen and inert gas back and forth, and under this condition, almost all adsorbed hydrocarbons and carbon are removed to increase the surface area. it can.

  Before activating the carbonized material, it is first charged by pickling or alkali washing. The choice of acid-alkali is determined by the chemical reagent selected when removing other components in the carbonization reaction. Many methods can be used for the activation process, but the most commonly used method involves blowing an oxidizing gas such as air, steam or carbon dioxide gas to treat the carbonized material. This type of technology is widely used in the activation of coffee mixtures and subsequent carbonization processes. The carbonaceous material reacts and is activated in steam at 800-1100 ° C., and at the same time, the amount of heat is uniformly distributed through the control of the atmospheric pressure in the fluidized bed reactor, thereby increasing the contact surfaces of the gas phase and the solid phase. The reaction between the steam and the carbonaceous material occurs on the back surface, so that more absorption sites can be provided for the released H2, CO2, and CO gas.

Initially, the carbonized material and steam cause the following vaporization reaction, which is also called a water gas reaction.
C + H2O-> CO + H2-175,440 kJ / (kg mol)
The above reaction is an endothermic reaction, and the reaction products CO and H2 can perform secondary combustion. The amount of heat released by the reaction is used to maintain the temperature of the entire reaction, and the reaction is as follows.
2CO + O2 → 2CO2 + 393,790 kJ / (kg mol)
2H2 + O2 → 2H2O + 396,650 kJ / (kg mol)

5. Preparation of masterbatch The carbonized particles obtained by carbonization preparation of the material containing coffee koji obtained in the above preparation or the material containing coffee koji from which organic components have already been removed are mixed with polymer polymer particles. be able to. In an embodiment of the present invention, 75% carbonized particles and 25% coffee scented material can be mixed and polished to fine particles of 5 micrometers (μm). A masterbatch is prepared by mixing particles (polypropylene, nylon or polyester) in a weight ratio of 1: 9. A masterbatch can also be prepared by mixing 75% carbonized particles and 25% coffee scented material directly with polymeric polymer particles (polypropylene, nylon or polyester). Note that the mixing ratio is not limited to the above example.

6. Preparation of yarn In order to produce a masterbatch to an industrially acceptable purity and color the fiber, a polymer melt containing a color masterbatch and the like is added to the masterbatch of each lot in the same manner. The reason why the masterbatch mentioned in Non-Patent Document 1 is designed in this way is that the fiber can be extruded in a normal production process. If necessary, the fibers are cut into short fibers or directly produced into long fiber yarns, and false twisting is applied. The fiber thus obtained does not need to be changed to any production method and can be used in the blending stage of the spinning process. It can also be produced directly into plain and knitted fabrics.
