Optimizing the finishing process is important to get the desired flexibility and dimension stability of main fabric. It is recommended to take the following steps of finishing process to optimize elasticity of XLA fabric.

To relax the fabric as much as possible to improve the flexibility
　　First processing of XLA fabric with flat treatment can maximally improve the flexibility of the fabric. The treatment should ensure the proper temperature and sufficient dwell time, keep the tension to a minimum level, and make XLA fabric as relax as possible in the treatment tank to enhance the flexibility of the XLA fabric.
　　1．Reduce warp tension and avoid stretching the fabric at weft direction. The equipment with active loading wheel is recommended to decrease the warp tension as much as possible.
　　2．Use continuous process with at least five washing sink for first . Gradually increase the water temperature from 50 ℃ to 85 - 90 ℃ and control the speed at 50m/min.This step is usually associated with desizing, refining and other pretreatment process.
　　3．Dwell time directly effect the relaxing treatment. To achieve the greatest degree of relaxation of the fabric, the appropriate treatment conditions should be based on the equipments currently used. Basically, the usual dwell time is about 15-30 minutes.

Fabric exposure to 130℃ or above to achieve maximum dimensional stability
　　The fabric reachs its minimum internal stress level around 130℃, and thereafter remains constant. Superior fabric dimensional stablility is achieved by combining maximum relaxation followed by exposure to 130℃. This step is usually associated with drying, shaping process.

The critical steps of finishing processes:
　　The critical steps to develop fabric's stretch and dimensional stability of XLA fabric can be combined with normal finishing process of non-elastic fabrics. The treatment temperature are not a limitation during processing for XLA fabrics. The XLA fabric can bears over 220℃ temperature without damage fabrics' elasticity.
　　The XLA fabric has excellent resistance to most chemical agents commonly applied in the textile industry, including acid, caustic, oxidative and reductive agents. As a result, the finishing process of XLA fabric is free to select any chemical agents and concentration of the agents without considering the restrictions of fiber.

Example of conventional finishing process

　　1、Singeing, Can be performaed without any particular settings in terms of fabric feeding velocity, flame power or orientation. 
　　2、Desizing and scouring, Can be performed under conditions commonly used for non-elastic fabric. For desizing, there is no limitations to the types of agents that can be applied to the stretch fabric. 
　　During the process, setting the proper temperature （Use continuous process with at least five washing sink for first heating. Gradually increase the water temperature from 50 ℃ to 85 - 90 ℃) and time (steaming,90-98 ℃, loose tension-free, 20 - 30 minutes）），controlling temperature though the whole implementation to ensure release, desizing and scouring to achieve the desired results
　　3、Mercerizing. Modifies the fabric's mechanical properties, luster and hand feel. In mercerization, the fabric is treated in a strong alkline solution, typically at low temperatures. XLA will not degrade in persence of caustic, high concentrations such as 270-300 g /L of alkali can be used. No restricts for subsequent acid neutralization washing process.
　The chainless machine is preferable to mercerize fabrics containing XLA fabric, since low tension or slack mercerization processes provide the opportunity to completely relax the fabric and enhance elasticity.
　　If chained mercerizing machines are preferred, the minimun required tension should be applied to the fabric.
　　4、Dyeing，No special requirements for dying process. The plant can use any dyeing process, just note that，do not apply tension—or reduce the tension to minimum to the elasticity direction of the fabric during the dyeing process ，so that the flexibility and the dimension stability of the XLA fabric will not be affected！
　　The drying would be performed after desizing, scouring or mercerizing. Drying can be done through direct contact with a hot surface like a heated cylinder, normally at a temperature highre than 120℃(248F); or with hot air flow as in a stenter framce at temperature between 130-150℃(265F - 300F). If a stenter frame process is used, minimum tension in the weft direction is recommended.
　　5、Sanforizing，is used to eliminate the internal tensions in weaving, dyeing & finishing, allowing the fabric to shrink before it is cut & sewn. For fabrics containing XLA, this process can be executed at typical conditions used for 100% cotton fabrics, no special requirements！
