Description

TECHNICAL FIELD

[0001] The utility model relates to composite fiber non -woven fabric wrinkle -resistant finishing technical field, concretely is a kind of composite fiber non -woven fabric wrinkle -resistant finishing device. BACKGROUND

[0002] Composite fiber non-woven fabric (such as polyester / polypropylene bicomponent fiber, SMS medical non-woven fabric, etc.) is widely used in medical, filtration, packaging and other fields due to its multiple fiber characteristics. In the manufacturing process of non-woven fabric (such as carding, laying, thermal bonding or chemical bonding), the fiber may generate internal stress due to stretching, thermal shrinkage or mechanical action. The composite fiber is more likely to cause uneven stress distribution and wrinkle due to the shrinkage rate and melting point difference of different components (such as PET and PP), and the surface flatness directly affects the product appearance and user experience. Wrinkles may cause poor sealing (such as medical protective clothing) or deformation of printed patterns (such as packaging materials), so it is necessary to perform wrinkle-resistant finishing on the composite fiber non-woven fabric during production.

[0003] Traditional wrinkle-resistant processes mostly use constant temperature hot pressing technology. When high temperature and pressure are directly applied to non-woven fabric with existing wrinkles, the thermal plastic deformation characteristics of the fiber cause stress concentration at the wrinkle site. Not only can the original wrinkles not be eliminated, but the wrinkle pattern may also be locked by thermal history during the cooling stage, forming permanent indentations. The operator needs to frequently stop the machine to adjust the wrinkle position and perform secondary hot pressing treatment, which disrupts the continuity of production, and the tension fluctuation introduced by manual intervention reduces the batch consistency of the product.
