Problems solved by technology

Leaving dressings inside the body is an extremely dangerous accident that can lead to patient deterioration and even death if not detected and removed in time
The disadvantage of the existing non-woven fabric is that it is not easy to be detected when it is left in the human body

Embodiment Construction

[0017] As shown in Figure 1, the production process of spunlace nonwovens containing X-ray imaging includes the following steps:

[0018] 1) Prepare materials: prepare raw materials, namely 100% pure natural cotton or a small part of synthetic fibers plus pure natural cotton;

[0019] 2) Flower cleaning: first, the raw materials are removed by a flower cleaning machine, the foreign matter in the raw materials is screened out, and the raw materials are opened. This step is a known technology and is the same as the prior art;

[0020] 3) Carding: use a carding machine to loosen and comb the raw cotton after cleaning;

[0021] 4) Cross-lapping: Spray liquid X-ray absorbing material into the web-laying process and solidify into X-ray developing lines. At the same time, according to the requirements of product weight specifications, the cotton web formed by preliminary carding is laid out in a reciprocating or cross-overlapping manner according to the direction of the cotton fiber...

Abstract

The present invention relates to hydro-entangled non-woven fabric, and is a kind of hydro-entangled non-woven fabric containing X-ray developer and its production process. The X-ray developer line may be added into or on the hydro-entangled non-woven fabric before winding, and is preferably implanted or sprayed to the fiber web before the hydro-entangling step so as to make the X-ray developer line and the fiber web entangled together. The present invention has reduced production process, lowered cost, less pollution, firm combination of the X-ray developer line and the fiber web, and raised product quality and safety.

Description

【Technical field】 [0001] The invention relates to a spunlace nonwoven fabric and a production method thereof, in particular to a spunlace nonwoven fabric containing X-ray developing objects and a production method thereof. 【Background technique】 [0002] With the improvement of non-woven fabric production technology and the reduction of cost, more and more non-woven fabrics are used in the medical industry, and non-woven fabrics are laminated to make multi-layer dressings, which are used for hemostasis, blood testing, blood sucking or body fluid. During the operation, the dressing falls into the human body due to subjective or objective reasons, and the dressing soaked in blood or body fluid is similar in color to the human tissue in the human body or in the wound, so it is extremely difficult to be found, so that it is left in the human body , and it is difficult to check out after the wound is sutured, unless the seam is re-cut. Leaving the dressing in the human body is ...
