LMW RESPIN: Circular Economy in Action for Recycled Fiber Processing

Introduction

The global textile industry is at a critical crossroads. With mounting pressure to reduce environmental impact and adopt sustainable practices, textile manufacturers are rethinking how yarn is produced. LMW RESPIN— a dedicated spinning solution for recycled fibers that champions circular economy principles while ensuring uncompromised productivity and quality.

"Recycle, Reuse, Respin": LMW's Mantra for a Greener Future

LMW RESPIN is not just a product line. It's a sustainability-driven transformation platform — designed to help spinning mills process recycled materials with precision, consistency, and profitability.

Understanding Circular Economy in Textiles
The circular model means utilizing recycled fibers—whether from post-industrial waste, post-consumer textiles, or PET bottles—and converting them into high-quality yarns. However, processing these variable and often challenging materials requires specialized technology and systems.

Traditional textile production operates in a linear model: take → make → dispose. In contrast, a circular economy focuses on:

1. Reducing raw material usage
2. Extending the lifecycle of fibers
3. Reintroducing waste into the value chain

That’s where LMW RESPIN comes in.

What is LMW RESPIN?:
LMW RESPIN is a commitment to a sustainable future. It is designed to intee sustainability, innovation, and performance, enabling textile manufacturers to adopt eco-friendly prgratactices. Various raw materials / feed materials are used in the recycled process. Virgin material of cotton and polyester are added as per the end product requirements.

LMW's Smart Series: Leading the Way in Recycled Fiber Processing
LMW's Smart Series machines are specifically engineered for mechanical recycling, making them ideal for processing a variety of recycled materials. These machines are not only efficient but also versatile, capable of handling different types of fibers with ease.

The Process: From Waste to Yarn
LMW’s solutions are built around a systematic approach to recycling. The process begins with waste classification, where raw materials are sorted based on the final product’s requirements. The materials can include:

• Fabric cuttings and hosiery waste
• Post-consumer used and unused textiles
• Recycled polyester and PET fibers

These classified materials are then processed through several stages, each designed to optimize resource use while ensuring minimal waste:

• Blowroom: The Blowroom process begins by opening the material into very fine tufts, preparing it for further cleaning and processing. Cleaning eliminates most impurities, such as seed particles and debris, ensuring cleaner fibers. In mixing or blending two or more types of fibers are blended to achieve a uniform and consistent mix. LMW's versatile GENTLE BLOWROOM LINE is designed to process cotton, manmade, and regenerated fibers, making it ideal for all spinning applications.
  
  

  The Gentle Blowroom Line includes the following machines:

  1. Bale plucker LA23/S, automated line with production capacity of up to 2000 kg/hr with auto scanning arrangement and suitable to process 4 assortments.
  2. Swift floc LA21, automated line with production capacity of up to 600 kg/hr, suitable to process 2 assortments.
  3. Varioclean LB9/2, Integrated opening, cleaning and dedusting machine with a production capacity of up to 1600 kg/hr.
  4. Unimix LB 7/4 and LB 7/6, High output of up to 800 kg/hr with 6 Chambers (LB7/4) and 1000 kg/hr with 8 Chambers (LB7/6). Enhanced value of mixing through homogeneous blending and efficient opening and cleaning with automatic grid bar to beater setting
  5. Flexiclean LB5/6, Controlled fibre feed for optimum opening and maximum cleaning efficiency with a production rate of up to 600 kg/hr with working width of 1200mm
  6. Supremoclean LB10/2, the machine is equipped with a pressurized feed chamber for material feeding, uniform filling by feeding flaps and trio feed roller for better compacting. The production capacity is up to 1000 kg/hr.
  7. Auto blend LA10, blending of various material with a maximum throughput of up to 2000 kg/hr (4 modules with max. 500 kg/hr each). Automatic feeding system without any Manual Intervention to blending accuracy levels of +/- 1%. Minimum blending ratio possible is 99:1
• Card: Carding machines align the fibers into thin webs, separating and cleaning them further. This step individualizes the fibers and converts them into a strand called the sliver.
  
  
  1. The LMW Card LC363 / LC361 is designed for high production—up to 150 kg/hr—with advanced features that ensure high-quality sliver across all varieties of cotton, man-made fibres, and blends. Card LC363 / LC361 is configured to produce better yarn characteristic with reduction in running cost.
  2. With LMW’s Card LC636 SX wider width card (1.5m) is engineered to boost both productivity and quality, making it ideal for modern spinning mills. It empowers mills to achieve superior yarn quality while significantly improving overall operational efficiency.
• Draw Frame (Breaker): In the Draw Frame process, the carded sliver is further refined to enhance its uniformity. This is achieved by improving its evenness across short, medium, and long lengths. The fibers are parallelized through drafting, ensuring they align uniformly within the strand.
  
  
  1. LMW’s LDB3 redefines the way Non-Auto leveller draw frames perform in spinning preparatory. It comes in two variants: Electronic drafting drive and Mechanical drafting drive. With unique feature of in-built closed loop digital sliver control system, LDB3 ensures highest degree of consistency in linear density of delivered sliver.
• Lap Former: Experience unmatched efficiency and quality with LMW’s Lap Former LH20 S, meticulously engineered for seamless integration with the LK69 Comber Series. Capable of delivering speeds up to 200 mpm and producing up to 680 kg/hr, this powerhouse boosts productivity while minimizing operational costs.
• Comber: The Comber process focuses on enhancing the quality of the fiber by removing short fibers and any remaining impurities from the material. This step ensures that only long and consistent fibers remain, resulting in improved yarn strength and quality. The fibers are then consolidated into a highly uniform strand called a combed sliver. Starting with the comber lap as input, this process produces a combed sliver that is highly refined and ready for further stages of spinning. LMW’s latest Comber LK69 S, represents cutting-edge technology engineered to deliver exceptional productivity and better fiber quality.
• LMW Draw Frame (Finisher): A Draw Frame Finisher is a crucial machine in the spinning process used to improve the sliver quality by doubling and drafting the carded or comber slivers. It aligns the fibers parallel, equalizes the sliver weight, and enhances fiber blending to ensure uniformity and consistency in the yarn quality.
  
  
  1. LMW’s Autoleveller Draw Frame LDF3 S is equipped with best in class in features like Servo draft, change gearless main motor, Auto piecing along with online sliver monitoring. Since LDF3 S delivers benchmark quality at affordable price, it became instant success among customers.
  2. LMW’s Twin Delivery Auto Leveller Draw Frame – LDF3 2S, a revolutionary solution designed to elevate spinning efficiency and sliver quality. With its innovative compact design, the LDF3 2S maximizes space utilization while delivering high performance.
• Speed Frame: The Speed Frame process takes the drawn sliver to achieve the desired thickness. A small amount of twist is introduced to hold the fibers together, forming what is known as roving—a pre-yarn intermediate state. The twisted roving strand is then wound onto bobbins, making it convenient for handling and transportation to the next stage. This stage transforms drawn sliver into roving, a crucial step toward creating high-quality yarn. LMW offers 𝗦𝗽𝗲𝗲𝗱 𝗙𝗿𝗮𝗺𝗲 𝗟𝗙 𝟰𝟮𝟴𝟬/𝗦𝗫 model with Auto doffer is the most advanced Speed Frame available in the market that provides highest value to the customer.
• Ring Frame: The Ring Frame process is where the roving is transformed into yarn. This begins with drafting, where the roving is drawn to a specific degree of fineness. The fibers are then twisted, creating a continuous and durable strand of yarn. LMW’s LRJ 9/SXL Ring Frame enhances productivity, efficiency and quality in the spinning industry. With cutting-edge technology and advanced features, it offers energy-saving, reduced footprint, high user and maintenance friendliness. A game-changer to elevate your spinning process.
