Embodiment 1

[0024] This example provides a method for preparing a low-fluff neurosurgical sheet, and prepares a low-fluff neurosurgical sheet whose short fibers are not easy to fall off and fluff.

[0025] like figure 1 As shown, the preparation method of the low-fluff neurosurgical sheet of the present embodiment at least comprises the following steps:

[0026] S001: Carding;

[0027] The cotton fiber is combed by a carding machine to remove impurities in the cotton fiber and remove too short and too fine cotton fibers.

[0028] S002: Laying the net;

[0029] The carded cotton fibers are placed in the web-laying machine for parallel laying or semi-cross-laying to minimize the interlacing between cotton fibers. Cotton fibers are laid in parallel or semi-cross-laid into fiber layers that are stacked together, and the ratio of the longitudinal strength (MD) to the transverse strength (CD) of the fiber layers is 1-6.

[0030] S003: Spunlace or acupuncture;

[0031] The laminated fiber l...

Embodiment 2

[0045] This embodiment provides a low-fluff neurosurgical sheet, which is prepared by the preparation method of the low-fluff neurosurgical sheet in Embodiment 1 above.

[0046] After carding, the low-lint neurosurgical sheet is made by parallel laying or semi-cross-laying, which reduces the interlacing between fibers and reduces the shedding of short fibers and fine fibers caused by product slitting; the surface of the low-lint neurosurgical sheet is compounded There are adhesives to reduce the shedding and fluffing of short fibers; X-ray development lines and traction lines are combined on the low-fluff neurosurgical sheet to avoid the low-fluff neurosurgical sheet left in the human body.

Abstract

The invention discloses a nerve operation sheet having low fiber shedding rate and a making method thereof. The making method of the nerve operation sheet having low fiber shedding rate comprises, atleast, the following steps that carding is performed, wherein fiber is carded, and impurities are removed; lapping is performed, wherein parallel lapping or semi-cross lapping is performed to form a fiber layer; spunlace or needling is performed, wherein the fiber layer is made into a non-woven fabric through spunlace or needling; compounding and forming are performed, wherein a bonding agent is compounded on the surface of the non-woven fabric; a finished product is obtained, wherein the non-woven fabric compounded with the bonding agent is split to obtain the nerve operation sheet having lowfiber shedding rate. Due to the fact that the nerve operation sheet having low fiber shedding rate is formed through parallel lapping or semi-cross lapping, fiber interlacing is decreased, the shedding rate of short fiber and thin fiber due to product splitting is reduced, the bonding agent is compounded on the surface of the non-woven fabric, and shedding and fluffing of the short fiber are decreased.

Description

technical field [0001] The invention relates to a medical dressing, in particular to a low-fluff neurosurgical sheet and a preparation method thereof. Background technique [0002] In clinical neurosurgery, neurosurgical sheets have a wide range of applications. From the protection of brain tissue and nerve tissue to tissue resection surgery, neurosurgical sheets are required. Due to the fragility and complexity of brain tissue and nerve tissue, clinically higher requirements are put forward for the materials used in neurosurgical sheets. Materials that need to directly contact brain tissue have liquid absorption, fit, anti-flocculation, and anti-sticking Attached, anti-pilling and other characteristics. [0003] The neurosurgical sheet currently on the market is a short-fiber non-woven material, which is a non-woven fabric formed by opening, carding, cross-lapping, and reinforcing with acupuncture or spunlace. Although it has strong water absorption capacity, it has disa...
