Abstract

The invention discloses a degradable environment-friendly garment fabric capable of repelling mosquitoes and absorbing sweat and a production process of the degradable environment-friendly garment fabric. According to the invention, natural mosquito-repelling components such as the lemon eucalyptus oil, the peppermint oil and the citionella oil are combined with the synthetic mosquito repellent such as IR3535, and the micro-encapsulation technology is utilized for encapsulation, so that the mosquito-repelling fiber can continuously release the mosquito-repelling components under the condition that the mosquito-repelling fiber is not in direct contact with the skin. The fiber has the advantages of long-term effectiveness and safety; the microencapsulation technology effectively prolongs the release period of mosquito-repelling components, and ensures that the fabric can still keep the mosquito-repelling effect after being used for a long time and washed for multiple times. Meanwhile, the mosquito repellent is packaged in the micro-capsule, so that the possibility of direct contact with the skin is reduced, and the risk of anaphylactic reaction is reduced. Besides, due to the addition of the mosquito repellent fibers, the fabric has the additional mosquito repellent function characteristic, so that the additional value of the product is improved, and the increasing requirements of users on healthy and environment-friendly life styles are met.

Description

Technical Field

[0001] The invention belongs to the technical field of clothing fabrics, and in particular relates to a degradable and environment-friendly clothing fabric capable of repelling mosquitoes and absorbing sweat, and a production process thereof. Background Art

[0002] Environmentally friendly clothing fabrics mainly include organic cotton, recycled fiber, bamboo fiber, modal fiber, corn fiber, etc. Organic cotton is cotton grown without the use of chemical synthetic fertilizers and pesticides, which not only reduces the pollution of chemical substances to soil and water sources, but also makes the fabric softer and more breathable. Recycled fiber is fiber that is re-spun from waste such as waste plastic bottles and waste silk, which effectively reduces waste emissions. With the enhancement of people's environmental awareness and the improvement of demand for healthy life, environmentally friendly clothing fabrics are becoming more and more popular among consumers.

[0003] However, traditional clothing fabrics often have the following problems: first, they are not environmentally friendly enough and are difficult to degrade, which puts a burden on the environment; second, they have a single function and cannot meet specific needs, such as mosquito repellent and sweat absorption. Although there are some fabrics with specific functions on the market, they often have problems such as short-lasting mosquito repellent effect, low comfort, and poor environmental protection.

The advantages of this fiber are its long-lasting effect and safety: the microencapsulation technology effectively extends the release cycle of the mosquito repellent ingredients, ensuring that the fabric can still maintain the mosquito repellent effect after long-term use and multiple washings. At the same time, since the mosquito repellent is encapsulated in the microcapsule, the possibility of direct skin contact is reduced, and the risk of allergic reactions is reduced. In addition, the addition of mosquito repellent fiber gives the fabric additional mosquito repellent functional characteristics, which not only increases the added value of the product, but also meets the user's growing demand for a healthy and environmentally friendly lifestyle.

Microencapsulation: For the volatile components of lemon eucalyptus oil, microencapsulation technology is used to encapsulate them in microcapsules to prolong their release time and improve their stability. This is usually done by phase separation, interfacial polymerization or spray drying technology. X2. Preparation of fiber raw materials: Select appropriate fiber raw materials, including polyester, nylon or cellulose, and pre-treat them by drying and purifying. X3. Addition of mosquito repellent ingredients: Masterbatch preparation: The pretreated mosquito repellent ingredients are mixed with the fiber raw materials, and granulated by an extruder to prepare mosquito repellent masterbatch. Mixing: Mix the mosquito repellent masterbatch with the base fiber raw materials evenly to ensure that the mosquito repellent ingredients are evenly distributed in the final fiber. X4. Fiber spinning: Melt spinning: The mixed raw materials are spun into fibers through the melt spinning process. In this process, the mosquito repellent masterbatch is melted together with the basic fiber raw materials and ejected from the spinneret, and then solidified into filaments after cooling. X5. Post-processing: Drafting: Drafting the spun fibers to improve their strength and uniformity. Heat setting treatment is used to improve the shape stability and other physical properties of the fibers. The fibers are washed to remove oil and other impurities on the surface, and then dried to produce mosquito repellent fibers.
