Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, and in particular to a nonwoven fabric with a drainage structure layer. Background Technology

[0002] Non-woven fabric, also known as nonwoven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is a fabric structure made by arranging short textile fibers or filaments in a directional or random manner to form a fiber web structure, and then reinforcing it by mechanical, thermal bonding or chemical methods. Non-woven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic and odorless, inexpensive and recyclable, and is often used in medical and health applications.

[0003] After surgery, existing surgical wounds or incisions require the use of non-woven fabric to cover them, preventing fluid from leaking out and contaminating clothing, or reducing infection at the wound site. However, when the wound requires intubation or tube placement, using existing non-woven fabric can cause inconvenience in tube fabrication, requiring staff to manually cut the non-woven fabric. This cutting process can damage the non-woven fabric and affect the normal drainage of wound fluid. Utility Model Content
