Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of preparation of environment-friendly bedspreads, in particular to a preparation process of environment-friendly bedspreads. Background Art
[0002] Bed covers, as an indispensable part of home life, have the main function of protecting mattresses from dust and stains and increasing the beauty of bedrooms. However, traditional bed covers often perform poorly in terms of antibacterial and anti-mite properties, and may also cause environmental pollution during the production process.
[0003] Traditional bedspreads are mostly made of conventional fabrics such as cotton, linen, and polyester, which do not have antibacterial and anti-mite properties. These fabrics are easy to absorb moisture, providing a suitable growth environment for bacteria and mites. In addition, the production process of traditional bedspreads is relatively simple, focusing mainly on the softness, breathability, and aesthetics of the fabrics, while ignoring the addition of antibacterial and anti-mite functions. During the production process, special antibacterial and anti-mite treatment technology is often not used, resulting in the bedspread being unable to effectively resist the breeding of bacteria and mites. On the other hand, in the production process of traditional bedspreads, in order to fix the fabrics and increase the stiffness and aesthetics of the bedspreads, a large amount of glue is often used. These glues usually contain harmful chemicals such as formaldehyde and benzene, which not only pose a threat to human health, but are also released into the air during the production process, causing environmental pollution.
[0004] For this reason we propose a preparation process of an environmentally friendly bedspread. Summary of the invention
[0005] The purpose of the present invention is to provide a preparation process of an environmentally friendly bedspread in order to effectively inhibit the growth and reproduction of bacteria and mites, reduce the risk of allergies and respiratory diseases, provide a healthy sleeping environment for users, avoid pollution caused by using traditional glue.
[0006] The technical solution adopted by the present invention is as follows: A preparation process of an environmentally friendly bedspread comprises the following steps: S1: Raw material selection, the surface fabric is 50 / 50 polyester-cotton fabric, the filling is high-density polyester fiber, and the base fabric is PVC laminated fabric; S2: Pre-shrink the fabric by soaking it in warm water for a while. After soaking, pick it up and gently wrap it with a dry towel or a cloth with good water absorption performance. Then press it gently to allow the towel or cloth to absorb excess water in the fabric. Then lay the fabric flat on a clean surface and gently stretch it to its original size by hand. Use a heavy object to flatten the fabric until it is completely dry, so as to reduce the size change caused by washing during subsequent processing and use; S3: Dyeing and printing, using special environmentally friendly dyes and environmentally friendly auxiliaries to dye or print the fabric to ensure bright and lasting colors; S4: Pretreatment of high-density polyester fiber: select masterbatch containing antibacterial and anti-mite ingredients, and mix polyester chips with antibacterial and anti-mite masterbatch in a certain proportion to ensure that the antibacterial and anti-mite ingredients are uniform in the fiber. Use melt spinning equipment to put the mixed material into the melt supply system, heat and stir it into a flowing state, and push the melt out and stretch it into filaments through an extruder. Cool the stretched fiber and send the cooled fiber to a rotary winder for winding to ensure that the fiber is evenly distributed. Then, open and comb the high-density polyester fiber with antibacterial and anti-mite properties to make it fluffy and uniform, thereby improving the hygienic performance of the bed cover. S5: Cutting of the face fabric, using high-precision cutting equipment to cut the face fabric, filling and base fabric according to size requirements, and leaving appropriate sewing allowances; S6: High-density polyester fiber filling, the high-density polyester fiber is evenly spread on the surface cloth, and the energy generated by the ultrasonic vibration of the ultrasonic welding machine melts the fiber instantly, forming a strong bond with the surface cloth, avoiding the pollution caused by the use of traditional glue; S7: Using polyester fiber as raw material to make PET sewing thread, and using the PET sewing thread to sew the surface fabric and the PVC laminated fabric; S8: Reinforce the corners of the bedspread by adding corner pads or extra sewing to enhance the three-dimensional sense and stability of the bedspread; S9: After finishing sewing, wash the bedspread for the first time to remove dust and stains that may have been generated during the sewing process; S10: Use low temperature drying technology to avoid high temperature damage to the material, shape the bedspread and keep the shape of the bedspread stable.
[0007] In a preferred embodiment of the invention, the high-precision cutting equipment is an automatic feeding laser cutting machine.
[0008] In a preferred embodiment of the invention, the environmentally friendly dye is a dual-active group reactive dye, and the environmentally friendly auxiliary agent includes a thickener, an adhesive, a crosslinking agent, an emulsifier, a dispersant, a color fixing agent and a leveling agent.
[0009] In a preferred embodiment of the invention, the proportion of the polyester chips is 75-90 parts, and the proportion of the antibacterial and anti-mite masterbatch is 10-25 parts.
[0010] In a preferred embodiment of the invention, the antibacterial and anti-mite masterbatch is prepared by mixing nano far-infrared powder, aluminate coupling agent, stearic acid, triphosphite and pentaerythritol ester.
[0011] In a preferred embodiment of the invention, the entire melt spinning device comprises a melt supply system, an extruder and a rotary winder.
[0012] In a preferred embodiment of the invention, the equipment used in the low-temperature drying technology is a low-temperature dryer.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, the high-density polyester fiber mattress cover filling is made of antibacterial and anti-mite masterbatch, which can effectively inhibit the growth and reproduction of bacteria and mites, reduce the risk of allergies and respiratory diseases, and provide a healthy sleeping environment for users.
[0014] 2. In the present invention, the high-density polyester fiber with antibacterial and anti-mite properties has suitable softness, and the polyester fiber itself is wear-resistant and durable and not easy to deform, thereby extending the service life of the bedspread.
[0015] 3. In the present invention, the energy generated by the ultrasonic vibration of the ultrasonic welding machine is used to melt the fiber instantly and form a strong bond with the surface cloth. The ultrasonic welding machine can accurately control the frequency, amplitude and duration of the ultrasonic wave to ensure that each welding can achieve the best effect, so that a strong molecular chain is formed between the fiber and the surface cloth. The welding strength is close to the strength of the raw material itself, which is strong and reliable, and also avoids the pollution caused by the use of traditional glue.
