Resuinsa, the sole sector business working with cutting-edge quality lab equipment

The laboratory includes equipment that measures the strength of thread and fabrics, electronic apparatus to regulate mass, optical spectrometers, and industrial washers and dryers.

The importance of textile quality is defined throughout the entire production process, from receiving the raw material to the final product sent out directly to customers. In this vein, Resuinsa—the leading international company in the hospitality sector—carries out the process in its quality lab located at its manufacturing centre in Anna (Valencia), home to one of the best technically equipped textile labs in Spain.

The quality of Resuinsa’s products has become a hallmark of the company, representing an element of trust sought out by customers, and enabling the firm to access new markets and develop new innovative projects.

In this sense, Resuinsa CEO Félix Martí explained that the firm works ‘to offer a top quality and exclusively designed product, in addition to the added plus of long-lasting durability. Our textiles are certified for industrial laundry, a highly aggressive process that can lead to high wear and tear for any item’. Therefore, these types of products need to be highly resistant and maintain their attributes over time, to ensure quality does not degrade.

Production process

From the arrival of raw materials to delivery of the fully finished product to customers, Resuinsa produces, controls and supervises each of the steps in this complex production chain at its quality lab. In this sense, it oversees all manufacturing process phases: spinning, weaving, dyeing and finishing, cutting and confection.

Quality control for both the thread and the fabric is carried out at the lab with specific technical instruments. Different equipment is used to determine the thread count, such as reeling machines, quadrant scales and precision scales.

In turn, the lab is home to the latest technology to determine the degree of polymerisation (DP) for items, and different friction meters, including the Martindale that determines whether lint or pilling forms or not, based on specific cycles. It has twist testers to determine thread twisting, doubling and latent twist energy, as well as dynamometers to determine thread and fabric traction force and elasticity to assess the irregularity of a thread mass, electronic equipment to regulate mass and instruments to determine thread and fabric friction.

Instruments linked to thread hairiness (a key parameter) are used as this directly impacts the appearance of a thread and the finished fabric, as well as an item’s crispness, softness or roughness.

The lab equipment is rounded out with essential technology such as optical spectrometers, a device that measures the amount of light reflected from and absorbed by a sample. In this sense, its purpose is to perceive colour difference, which is essential when designing tailored, unique textiles.

Resuinsa’s quality lab is also home to machines such as the Tin-control to test colour fastness in fabrics; industrial washers and dryers to perform tests; ironing and calendering equipment to reproduce what happens in an industrial laundry service; light boxes to detect colour contamination and difference, and review screens to spot any possible impurities and defects in the fabric.

Thanks to all these technical devices, the most common tests determine a range of elements including the composition of cotton or linen fibres by using a microscope, thread strength, the thread count per unit of length, colour affinity, degree of polymerisation and tear resistance.

In short, Resuinsa assures every textile manufacture stage at its quality lab through the latest technical advances. A space that is truly second to none in textile innovation in Spain.
