Knitting Circular Knitting Machine Single-sided loop Knitting machine: Structural Features and Application Guide

Single-sided circular knitting machine Structural Features and Application Guide: The single-sided loop knitting machine is a dedicated derivative model of the single-sided circular knitting machine. Through a special loop forming mechanism design, it can form a uniform and fluffy loop structure on one side of the fabric. It is widely used in the large-scale production of towel fabrics, sweatshirt fabrics, and home textile fabrics, and has the core advantages of high weaving efficiency and diverse fabric styles. I. Core Structural Features of Single-sided Ring Forming Machine: Based on the conventional single-sided large circular machine, the single-sided ring forming machine optimizes key components according to the ring forming requirements. The structural design focuses on “stable ring formation and controllable rings” : 1. Weaving mechanism: The core of ring forming is equipped with dedicated ring needles and settling plates. The body of the loop needle is longer, and the hook position is precisely adapted to the hooking and hanging of the loop yarn. The settling plate is equipped with a loop control step. By adjusting the relative position between the settling plate and the knitting needle, the height and density of the loops can be precisely controlled to prevent them from topover or falling off. Triangular device zoning design: It is divided into loop triangle, loop triangle and loop unloop triangle. The Angle and travel of the triangular track have been specially adjusted, which can not only ensure that the ground yarn forms a stable ground structure, but also allow the loop yarn to form regular loops on the fabric surface. At the same time, the length and style of the loops can be quickly switched by adjusting the position of the triangle. 2. Yarn feeding mechanism: The double-track yarn is precisely synchronized. A double-track yarn feeding system is adopted, respectively conveying ground yarn and loop yarn. The tension of the two yarn feeders is independently adjusted: the tension of the ground yarn is slightly larger to ensure the compness of the ground weave. The tension of the loop yarn is moderate, avoiding the loop being pulled apart due to excessive tension or becoming loose due to insufficient tension. Some high-end models are equipped with electronic yarn feeders, which can adjust the yarn feeding amount in real time according to the weaving speed, to meet the loop weaving requirements of different yarn materials (pure cotton, polyester-cotton, bamboo fiber, etc.). 3. Drawing and winding mechanism: The drawing roller is made of soft rubber material to adapt to the characteristics of the loop fabric, increasing the friction with the fabric and avoiding snagging and damaging the loop during the drawing process. The drawing speed is precisely synchronized with the weaving speed to prevent fabric from stretching and deforming, ensuring uniform loop distribution. The winding device is equipped with a tension buffer structure. The tension of the wound fabric is slightly lower than that of the conventional single-sided machine, preventing the loops from being squeezed and deformed, and ensuring the neat appearance of the fabric roll. 4. Electrical control System: Convenient adjustment of process parameters. Integrated touch screen operation interface, allowing direct setting of parameters such as loop height, loop density, and weaving speed. Supports storage and invocation of process parameters, eliminating the need for repeated debugging when changing fabric varieties. Equipped with broken yarn and floating thread detection sensors, it will automatically shut down when a fault occurs, reducing fabric defects and raw material loss. Ii. Key Points of the Weaving Process for Single-sided loop Knitting Machines 1. Yarn Selection and compatibility: Prioritize the use of high-strength, uniform strip-dry cotton or polyester-cotton yarns to ensure the stability of the fabric. The loop yarn can be selected as pure cotton yarn, bamboo fiber yarn or ultra-fine denier polyester yarn according to the requirements. The loop of pure cotton yarn is soft and skin-friendly, suitable for towel fabric. The polyester yarn loops are crisp and wear-resistant, making them suitable for sweatshirt fabrics. The yarn needs to undergo pre-loosening and humidification treatment to reduce static electricity and breakage rate during the weaving process. 2. Process parameter adjustment: The height of the loop is controlled by adjusting the position of the settling plate and the triangular stroke. The height of the loop for conventional towel fabric is 2-4mm, and for sweatshirt fabric, it is 1-2mm. The coil density is adjusted according to the fabric weight requirement. The greater the weight, the higher the coil density. Control the weaving speed. For complex loop patterns or fine and weak yarns, reduce the vehicle speed to avoid poor loop formation. 3. Daily maintenance of the equipment: Regularly clean the yarn impurities in the needle slots and settling plate slots to prevent jamming and affect the formation of the loops. Special knitting machine oil should be selected as the lubricating oil. The oil output of the oil needle should be adjusted to 1-2 drops per minute to prevent oil stains from contaminating the loop fabric. Regularly inspect the wear and tear of the knitting needles and settling plates, and replace damaged parts in a timely manner to prevent defects such as missed needles and uneven ring sizes. Iii. Application Scenarios and Product Advantages of Single-sided Loop Knitting Machine 1. Core application fields: Home textiles: Weaving towel cloth, bath towel cloth, bath curtain cloth. The loops are fluffy and absorbent, skin-friendly and comfortable. Clothing fabric category: Woven sweatshirt fabric, casual wear fabric. The loops on one side are warm, and the back side is smooth and can be printed. Industrial fabrics: Woven cleaning and wiping cloths, with strong ring adsorption, wear-resistant and durable. 2. The core advantages of the product: The fabric has single-sided loops and is single-sided smooth, combining both aesthetics and practicality. The weaving efficiency is higher than that of double-sided loop machines, making it suitable for large-scale production in large quantities. By changing the yarn and adjusting the process, diverse designs of loop length and density can be achieved to meet the differentiated market demands.
