The success of Tra Ly Hung Yen, based in Hung Yen Province, Vietnam, is built on a long-standing reputation for quality spun cotton yarns.

The family-owned company mainly produces carded and combed cotton in counts from Ne 20-40, employing both standard and compact spinning routes, with a production capacity of 60 tons per day.

Half of its output is exported to China, Pakistan or Bangladesh, but finding skilled operators for spinning mills in Vietnam is becoming increasingly difficult as the nation’s rapid industrialisation creates competition for young talent.

In addition, raw material fluctuations add extra challenges for all spinners, because to produce yarn with consistent quality, it is necessary to make precise adjustments to the processing systems.

To overcome these challenges, Tra Ly has looked to Trützschler to provide highly automated, self-optimising machinery that helps to maintain consistent quality – even when processing raw materials of varying quality. This reduces the need for manual intervention.

“Innovations from Trützschler offer efficient handling that frees up time for our employees,” says Tra Ly director Do Thi Lan Phuong “As a result, we are able to cope with labour shortages. These machines enable higher productivity, improved sliver evenness and more energy-efficient manufacturing.”

Trützschler’s technical experts are helping Tra Ly to improve its production processes and settings and among advanced technologies it has installed are a T-SCAN TS-T5 foreign part separator which employs state-of-the-art sensors and image-processing technology to detect stems, leaf fragments and other waste and automatically eject them to minimise fibre loss. The highly efficient machine is also easy to clean and maintain, even when production is running.

Self-adjusting system

Tra Ly operates numerous Trützschler carding machines and recently added a TC 19i with T-GO – the world’s only proven automatic gap optimiser for carding machines. It increases quality and flexibility by self-adjusting to ensure the best possible carding gap settings in real time, even when raw materials or other production conditions fluctuate.

Automated functions like Auto Draft and Opti Set meanwhile  enable the TD-10 autoleveller draw frame to ensure excellent yarn quality by self-optimizing the break draft and drafting point in real time. These innovations help machine operators to adapt settings for various raw material types.

A 12-head TCO 21XL comber further increases productivity by about 50% because it operates 12 heads instead of a typical eight head setup, while delivering the same quality. Count monitoring performs automatic checks on sliver count variations from a given limit, contributing to consistent quality.

Trützschler’s local team of technical experts, along with its well-stocked spare parts inventory and repair facilities in Vietnam, ensure that Tra Ly maintains high levels of productivity with reliable quality.

Using the My Mill mill monitoring system, Trützschler experts can even conduct digital audits to provide on-site guidance, training and troubleshooting based on real-time data.

As a result, Tra Ly can rely on outstanding customer service  and downtime is kept to a minimum.

“Working together with Trützschler is always a great experience because of their deep expertise, can-do attitude and positive energy,” says Do Thi Lan Phuong.
