Methods in the finishing stage of synthetic fabrics

A finishing technology that provides textiles with the ability to resist bacterial growth in clothing or textiles in general. Due to the increasing demand for textiles to be used for the needs of bacteria that are easily generated and developed, such as carpets, public places, and even on underwear fabrics no conditions for long-term washing, such as military-use clothes …

Products with organic metal (Organometallic compound) such as silver or zinc; or brominated phenols, quaternary ammonium compounds, etc., which are used in the form of a solution or dispersed into fiber components or processed in the form of thin film on fibers, which inhibit bacteria growth. . Limiting the arising of odors as well as the possibility of harmful effects of bacteria in textiles when in contact with human skin.
In addition, there are many other complete technologies such as: Against insects such as mosquitoes; Anti-slip fiber cloth; Hardened; cloth filling; strengthened. .. In particular, recently special measures have been applied for nanotechnology to give fabrics with special features that are completely environmentally friendly, minimize the impact on the environment, and save resources. nature, reducing production costs … For example, with dyeing technology, which is the cause of pollution due to huge emissions … now, people can apply fully dyeing technology Do not use to water called drying or DRY DYEING; or minimize environmental impact like ECODYE …

Other finishing technologies make textile products at the same time have many Vietnamese features such as: sweat-absorbing, quick-drying, waterproofing for outdoor use, quick drying 3XDRY ; External UV protection, lowering the internal temperature so that outdoor activists are not harmed by UV rays and feel cool COLDBLACK … And finished with the ability to add Vitamin A, E for human skin, …

Thermoforming of synthetic fabrics is a processing step to eliminate the unstable potential part of the fibers generated and hidden in the manufacturing process. This stage creates a new steady state (Resetting) and is fixed by rapid cooling after heating and rearranging. Fabrics after thermal shaping will avoid shrinkage or wrinkling. It is also possible to apply heat fixation in the state of the rustic fabric to avoid harm that reduces the color fastness of the fabric due to sublimation or movement of the dye from inside the fiber core to the surface when the fiber is heated The fiber is in a glass state at high temperatures. In other cases, this stage may also be combined with other technological purposes such as Thermasol dyeing or optical white for polyester. This is a final and useful finishing step to achieve the state of fabric stability along with the desired processing purposes.

Increase hydrophilic finishing (Hydrophilic finishing)
wicking_image The natural feature of synthetic fibers is their ability to absorb water and moisture. This causes an unpleasant sensation when the human skin comes in contact with the fabric. Sweat cannot dry on the skin creating high humidity, favorable for bacteria to grow, creating a body odor. To overcome this drawback, one can process fabric with hidrophylic silicone auxiliaries to create hidroxyl (-OH) groups on the fabric surface, these hydrophilic groups cause water or moisture to spread on A large surface area, makes water evaporate quickly, moisture is released, the skin feels dry. In addition, this process of evaporation is also a process of absorbing heat on the body, making the wearer feel cool. It feels like when we wear clothes made from natural fibers like cotton, linen …
