Abstract

The invention relates to a hydrocolloid oil yarn. The hydrocolloid oil yarn comprises a base material and a hydrocolloid ingredient, wherein the base material is netty polyester fiber; the hydrocolloid ingredient comprises the following raw materials in parts by weight: 8 to 10 parts of thermoplastic elastomers, 16 to 30 parts of sodium carboxymethylcellulose, 1 to 5 parts of growth factor microspheres, 1 to 5 parts of chitosan, 100 to 200 parts of liquid paraffin, 30 to 40 parts of Vaseline and 5 to 10 parts of wool fat. The content of grown factors inside the grown factor microspheres is 0.01wt% to 0.03wt%.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to hydrocolloid oiled yarn and a preparation method thereof. Background technique [0002] Human skin can not only stabilize the internal environment of the human body, but also prevent the invasion of bacteria and microorganisms. When the skin is injured and the homeostasis of the internal environment is broken, medical dressings, as a medical wound healing material, can provide the necessary protection to the human body and reduce the degree of harm. Before the skin recovers, a good medical dressing can temporarily play a part of the skin covering function and provide favorable conditions for wound healing. [0003] Existing dressings have a slow wound healing rate, mostly play the role of wound drainage, covering and filling, and tend to adhere to the wound during the healing process, resulting in bleeding, causing secondary injuries, and pain after the patient changes the dress...
