Abstract
The present invention relates to a kind of blended fiber of chitin-amine and hydroxypropyl cellulose as well as its preparing method and the usage. It is produced according to the composition of weight percent: 50.0-99.0% of chitin-amine and 1.0-50.0% hydroxypropyl cellulose, wherein the blended fiber is added with water soluble hydroxypropyl cellulose, thus increasing the hygroscopicity in the fiber and medical dressing made of the fiber, which is especially applicable to dressing the wound with bleeding or pus. The invention can extend the time of use for the product and help to heal the wound.
Description
Technical field:
The present invention relates to the material field, be specifically related to a kind of chitosan and hydroxypropyl cellulose blended fiber and preparation method and application.
Background technology:
Wound is a kind of common symptom, and the treatment wound need be with a large amount of medical dressing.Bleed at some and to suppurate on the more wound, medical dressing plays the effect that absorbs purulence blood on the wound, protection wound and promote its healing.
Chitin (claiming chitin, chitin, glutelin, crab shell chitosan again) is a cellulose second largest natural macromolecular material afterwards, and its chemical constitution is (1,4)-2-acetamido-2-deoxidation-callose.Chitosan (claiming shitosan again) is a kind of macromolecule aminated polysaccharide that chitin obtains behind deacetylation, and its molecular structure is (1,4)-2-amine-2-deoxidation-callose.Chitosan can dissolve as solvent with 2% aqueous acetic acid.After can being squeezed into 5% the NaOH aqueous solution by spinneret orifice, the spinning solution that contains 5% chitosan forms fiber.
As a kind of fibrous material, chitosan fiber can be processed to yarn, woven fabric, knitted fabric and non-woven fabric material.The material of being made by chitosan fiber can be processed to medical dressing, is used to administer the wound of bleeding and suppurating.This class dressing has hygroscopicity and moisture retention preferably, more can promote the multiple of wound compared with traditional cotton gauze.
Summary of the invention:
Technical problem to be solved by this invention is to improve the performance of existing chitosan fiber, and stronger chitosan of a kind of hygroscopicity and hydroxypropyl cellulose blended fiber material are provided.
Chitosan disclosed by the invention and hydroxypropyl cellulose blended fiber are that chitosan 50.0-99.0% and hydroxypropyl cellulose 1.0-50.0% make by the percentage by weight prescription.
The preferred percentage by weight prescription of blended fiber of the present invention is a chitosan 85.0%, hydroxypropyl cellulose 15.0%.
Another technical problem to be solved by this invention is to provide the preparation method of above-mentioned blended fiber.
Chitosan disclosed by the invention and hydroxypropyl cellulose blended fiber are to be carrier with the chitosan, with water miscible hydroxypropyl cellulose is additive, press formula ratio dissolves chitosan back and hydroxypropyl cellulose with 2% acetum aqueous solution, mixed solution forms fiber clamp-on 5% the NaOH aqueous solution by spinneret orifice after, makes after washing, drying.
A technical problem more to be solved by this invention is to disclose the application of above-mentioned blended fiber as medical dressing.
The blended fiber of chitosan of the present invention and hydroxypropyl cellulose has the performance of general fiber, can be processed to yarn, woven fabric, knitted fabric and non-woven fabric material, also can be with forming coating cotton thread after polyester fiber or other fibre-coated.
After being processed to yarn, woven fabric, knitted fabric and non-woven fabric material; product of the present invention can form medical dressing by cutting packing back; the more wound of suppurating that is used to bleed plays and absorbs purulence blood on the wound, and the protection wound also promotes the effect of its healing.
The blended fiber of chitosan of the present invention and hydroxypropyl cellulose has the biologically active of chitosan.Owing to added water miscible hydroxypropyl cellulose in the fiber, when the diffusate of blended fiber and water or wound contacts, hydroxypropyl cellulose in the fiber can suck fiber to a large amount of moisture, thereby increases the moisture pick-up properties of fiber and the medical dressing that is become by fiber process.
The made medical dressing of blended fiber that adopts chitosan of the present invention and hydroxypropyl cellulose is because the medical dressing of making than pure chitosan fiber has higher hygroscopicity, can prolong the service time of product in the time of on using the more wound of suppurating, reduce the replacing number of times of dressing, can reduce on the one hand the cost of nuring wound, also reduce the misery of patient when change dressings more on the other hand.Product of the present invention does not have toxicity to human body, can promote the healing of wound.
The invention will be further described below by example.
The specific embodiment:
Embodiment 1,
42.5 the chitosan powder of gram is dissolved in 2% aqueous acetic acid of 800 grams.In another container, the hydroxypropyl cellulose of 7.5 grams is dissolved in the deionized water of 150 grams.After two kinds of macromolecules fully dissolve, two kinds of solution are mixed in a container and the abundant uniform spinning solution of back formation that stirs.Is solution 30 with measuring pump in hole count under pressure, and the aperture is to clamp-on in the water-bath that contains 5%NaOH on 150 microns the spinnerets to form strand, obtains the blended fiber of chitosan and hydroxypropyl cellulose through washing and drying.Resulting long fiber can be processed into fabric with woven or knitting method after twisting, be processed into non-weaving cloth with non-interlaced fabric equipment after also can becoming 5 centimeter length to fibre cutting, through being processed into the gauze for the usefulness that cures the wound after the cutting packing.
Embodiment 2,
Chitosan among the embodiment 1 and the needle fabric that is processed into every square metre 120 grammes per square metre after the blended fiber of hydroxypropyl cellulose is cut off into 5 centimeter length with non-interlaced fabric equipment.Resulting non-weaving cloth is cut into 5cm * 5cm, the Gauze of 10cm * 10cm and 10cm * 20cm.Gauze is cut into 5cm * 5cm size, and the weight that records is W
1Gram.This piece gauze is placed on than (the A solution of British Pharmacopoeia regulation has imitated the content of sodium and calcium ion in the human body in its heavy 40 times A solution, contain 142 mM sodium chloride and 2.5 mM calcium chloride), directly through be in 90 centimetres the culture dish 37 ℃ place 30 minutes down after, hold a jiao of gauze under the arm with tweezers and hang the weight in wet base W that measures gauze after 30 seconds aloft
2Gram.(W
2-W
1)/W
1Hydroscopicity for the gauze of Unit Weight.The hydroscopicity of the gauze of being made by the chitosan and the blended fiber of hydroxypropyl cellulose of preparation among the embodiment 1 is 17.5 gram/grams, and the hydroscopicity of the gauze of being made by pure chitosan fiber is 14.2 gram/grams.
