Anteprima Fiera 2023 (1)

Since China opened up its economy in December of last year, it has become possible for us to travel overseas to visit our clients abroad. This is an exciting time for our company, as we have been affected by the impact of COVID-19 for the past three years, and we are now ready to expand our yarn products in the overseas market.   As a leading yarn manufacturer in China, we have always strived to maintain good relationships with our customers both locally and internationally. However, due to the travel restrictions and lockdowns caused by the pandemic, it was challenging for us to maintain those relationships effectively. We had to adapt to remote communication methods such as video conferencing and virtual meetings, which were not always ideal for building strong business relationships.   Therefore, the news that China would open up its borders came as a relief to us. We immediately began planning our trips to visit our clients abroad, where we could meet face-to-face and discuss our plans for expanding our yarn products in the overseas market. Firstly, we participated in the SaigonTex&SaigonFabric held in Vietnam in April.We understand that the international market is highly competitive, and we need to be proactive to stay ahead of our competitors. We believe that building strong personal relationships with our clients is crucial to our success. One of our main goals is to introduce our latest products to our clients abroad. We take pride in our high-quality products, and we believe that they will be well-received by the international market. We want to showcase our products in person to potential clients and demonstrate their unique features and benefits. We also plan to collect feedback from our clients regarding our products, which will help us improve our future offerings.   Another goal of ours is to identify new markets for our yarn products. We will attend The International Istanbul Yarn Fair in Türkiye in June,Our booth number is 1011A. Welcome to our booth.We recognize that different countries have different needs and preferences when it comes to textiles. Therefore, we plan to conduct market research and analysis to understand the demand for our products in various regions. By doing so, we hope to expand our customer base and increase our sales revenue. We are excited about the opportunities that lie ahead, but we are also mindful of the challenges that we may face. One of the biggest challenges for us is navigating international trade regulations and customs procedures. We must ensure that we comply with all relevant laws and regulations to avoid any legal issues. Additionally, we need to be aware of cultural differences and adapt our business practices accordingly to avoid misunderstandings or miscommunications.   Overall, we are optimistic about our prospects in the overseas market. We believe that our commitment to quality and customer service will set us apart from our competitors. We are eager to strengthen our existing relationships with our clients abroad and establish new partnerships in different regions.

Filati Intrecciati NIM SIM HIM

Intermingled yarn In the production of Synthetic yarn, especially elastic yarn with plies or a combination of two materials, the mingling technique dramatically impacts the physical properties of the final product. In Derun's factory, textured yarn and air-covered yarn can be fed into a nozzle with compressed air and be intermingled. [picture] NIM (Non-Intermingled), SIM (Semi-Intermingled), and HIM (High-Intermingled) yarns are three types of synthetic yarns that are commonly used in the textile industry. These yarns differ in the level of intermingling between the filaments and their physical properties. Here are some differences between NIM, SIM, and HIM yarns: 1. Level of intermingling: The level of intermingling between the filaments is the main difference between these yarns. NIM yarns have no intermingling (0-10 knots per meter), SIM yarns have a low to medium level of intermingling (40-50 knots per meter), and HIM yarns have a high level of intermingling (100-120 knots per meter). 2. Filament arrangement: The arrangement of filaments in NIM, SIM, and HIM yarns is different. NIM yarns have parallel filaments that are not twisted or intermingled. SIM yarns have slightly twisted filaments that are partially intermingled. HIM yarns have filaments that are highly twisted and tightly intermingled. 3. Physical properties: The physical properties of NIM, SIM, and HIM yarns are different. NIM yarns have low elasticity and bulkiness, while SIM yarns have moderate elasticity and bulkiness. HIM yarns have high elasticity and bulkiness, making them more suitable for use in stretch fabrics and other applications where a high degree of elasticity is required. 4. Production process: The production process for NIM, SIM, and HIM yarns is different. NIM yarns are produced without any additional processing after extrusion and drawing. SIM yarns are produced by partially intermingling the filaments during the texturing process. HIM yarns are produced by highly intermingling filaments during the texturing process. Intermingled yarn is a type of synthetic yarn that is used in various textile applications. The intermingling of the yarns during this process creates a more stable and stretchable yarn with improved properties. The quality of the intermingled can be improved by controlling the process parameters such as the air pressure, nozzle design, and heat-setting temperature and time to create a stable and stretchable product.

Introduzione del filato di copertura dell'aria a un passaggio

Nylon and spandex one-step air-covered yarn is a specialized type of one-step air-covering yarn that is made by combining nylon and spandex fibres using compressed air. This yarn is created by twisting together a continuous filament nylon yarn and a spandex fibre, resulting in a yarn with excellent elasticity, softness, and durability. Nylon is a strong and durable synthetic fibre that is known for its strength, abrasion resistance, and excellent drape. Spandex, also known as Lycra, is a stretchy synthetic fibre that is known for its excellent elasticity and ability to retain its shape. The combination of these two fibres in the one-step air-covered yarn creates a fabric that is both strong and stretchy. The one-step air-covering process used to create this yarn involves passing the nylon and spandex fibres through a high-pressure air jet. The air jet twists the fibres together, creating a yarn that is soft, fluffy, and elastic. The resulting yarn has a smooth, uniform appearance and is suitable for a variety of applications. [Sketch] Elasticity: Nylon and spandex one-step air-covered yarn are highly elastic, meaning they can stretch significantly and then return to their original shape. This property makes it ideal for use in clothing that needs to fit snugly and move with the body. 1. Softness: The combination of nylon and spandex fibres in the one-step air-covered yarn creates a yarn with a soft and fluffy texture. This softness makes the yarn comfortable to wear and touch. 2. Durability: Nylon is a strong and durable synthetic fibre that is resistant to wear and tear, while spandex is known for its ability to retain its shape over time. Together, these fibres create a yarn that is highly durable and long-lasting. 3. Moisture-wicking: Nylon and spandex one-step air-covered yarn can wick moisture away from the skin. This property makes it ideal for use in clothing that needs to stay dry, such as athletic wear and swimwear. 4. Breathability: The air pockets created by the one-step air covering process make the yarn breathable, allowing air to circulate through the fabric. This property makes the yarn comfortable to wear in hot weather. 5. Smoothness: The one-step air-covering process creates a smooth and uniform appearance for the yarn. This property makes it ideal for use in clothing that needs to have a sleek and streamlined appearance. Nylon and spandex one-step air-covered yarn is commonly used in the production of athletic wear, swimwear, and lingerie. The yarn's excellent stretch and recovery properties make it ideal for use in activewear, where it can provide a snug and comfortable fit that moves with the body. In swimwear, the yarn's durability and resistance to chlorine make it an excellent choice for fabrics that are exposed to water and sunlight. In lingerie, nylon and spandex one-step air-covered yarn is often used to create fabrics that are both soft and supportive.

Tour virtuale alla fabbrica di Derun

Welcome to the virtual tour of Derun's Factory! As we step into the factory, the first thing we see is our raw material warehouse, including nylon6 chips, nylon and polyester POY yarn and spandex yarn. PA6 chips melting spinning equipment. This equipment is used to melt and spin nylon chips into yarn. The chips we using is Polyamide 6, a type of nylon polymer that is commonly used in the production of textiles. Derun also equipped the masterbatch metering pump to control dope-dyed yarn production. The pump provides a controlled release of pigment masterbatch into the nylon chip melting system, that's the key to the uniformity of colour. The chips are heated and melted before being extruded through spinnerets, which are small holes that shape the yarn into specific dtex and filaments. The POY than be feed in to the spinning machine, POY stands for “partially oriented yarn,” which means that the yarn has been stretched to a certain degree but not fully. Next, we move on to the POY draw texturing machine, Derun uses this machine to produce nylon 6 DTY. This machine adds texture to the yarn by using heated rollers to twist and stretch the yarn further. This process improves the yarn's strength and makes it more suitable for use in fabrics and other textiles. Finally, we come to the one-step air-covering machine. This machine is used to combine two or more yarns to create a single yarn with improved characteristics such as softness, stretchability, and strength. The process involves wrapping one yarn around another while passing both through a high-speed air jet. This creates a uniform covering around the yarns, resulting in a high-quality, finished product. As we end our tour, we can see the intricate and fascinating process involved in the production of nylon yarn. The use of advanced equipment and technology ensures that the yarn produced is of the highest quality and meets the stringent requirements of the textile industry.
