Abstract

The invention discloses a preparation method for an anti-flaming type medical non-woven fabric. The preparation method comprises the following steps: S1) adopting a material absorbing machine for absorbing and guiding a mixture of fine fiber polymer to a heater for heating under heating temperature at 260-280 DEG C, thereby acquiring a polymer A under molten state; S2) adopting an extruding machine for pressurizing and spinning the polymer A under 4.8-5.3MPa, stretching spun yarns by a stretching machine, forming drawing fibers B, guiding the drawing fibers B into a soaking solution, soaking for 6-8h, and then guiding to a netting machine; S3) guiding overlapped fibers into a hot mill for hot milling when three or four layers of drawing fibers B are overlapped on the netting machine, uniformly spraying resin powder and aluminum hydroxide anti-flaming grain powder onto the drawing fiber surfaces while hot milling under the conditions of 160-180 DEG C and 4MPa, acquiring the non-woven fabric, winding and forming. On the basis of guaranteed toughness, the anti-flaming type medical non-woven fabric has an anti-flaming capacity and is especially suitable for hospitals.

Description

technical field [0001] The invention relates to the field of non-woven fabric preparation, in particular to a method for preparing flame-retardant medical non-woven fabric. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure. The advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven fabrics Cloth bags are easy to form and inexpensive to make. [0003] Non-woven fabrics are widely used in the medical field. At present, the non-woven fabric products used in hospitals cover various aspects, such as wo...
