Specific medical non-woven fabric using range and development
Since entering the 21st century, our country's non-woven technology achieved great progress, rising consumer demand, nonwovens equipment manufacturing, raw material production and products processing formed a full range of supply chain system, including medical non-woven fabric production and application development is particularly prominent.
Medical non-woven fabric can be further processed into artificial skin, prevent adhesive gauze, surgical clothes, cover the substance of resistance, XiaoDuBao cloth, protective clothing, masks, antibacterial cloth, diapers, sanitary napkins, sanitary pads and civil cloth, wiping cloth, wet towel, towel, soft towel roll, beauty products, etc.
Mainly adopts spun-bonded, hot melt compound and water three process, PP spun viscose cloth production health cloth, sanitary napkin and sanitary pads, hot melt composite fabric spunlace cloth is strictly controlled operation for personal care and environmental protection products.
The latest spinning into network combined with melt-blown superfine melt-blown fiber (
Diameter 2 ц)
And FM fine denier fibers (
The fineness of 0.
SMS/SMMS non-woven materials, products made uniform texture soft, good tensile strength and liquid barrier, the advantages of hydrophilic, waterproof, anti-static, anti-aging, dedicated to PP spun-bonded and SMS, spunlace nonwoven (
Viscose and polyester blend fabric)
And elasticity of medical acupuncture non-woven fabrics and other health care products processing.
Global non-woven production 4. 5 million tons in 2004, 05 keep 7.
5% of the growth rate and is expected to 09 6. 4 million tons.
Due to the sanitary napkin surface material is lightweight, same weight increase of the total area of the coil.
Domestic non-woven production 830000 tons in 2004, four years grew by an average of 18%, in 2009 total close to the United States, and Europe.
Disposable medical non-woven fabric, sanitary towels, diapers and care product demand is growing, small nonwoven coil exports, 50% products export.
Non-woven fabrics imported into negative growth after 2003, exports to 16% growth.
Spunlace method, spun-bonded method is of the fastest growing domestic non-woven technology in recent years, followed by acupuncture and thermal bonding.
Our self-developed moderate price of PE/PP sheath-core composite staple fiber is used for processing health materials with hot-rolled non-woven, making health care product with 100% fabric hot non-woven PE/PP composite staple fiber, the requirement for high polymer material and surface treatment agent than hot-rolled non-woven medical non-woven fabric is diagnosis and treatment of necessities, like medical protective clothing, infection control products, incontinence supplies, surgical gauze and ward equipment during the period of 'SARS' in 2003 to become a hot commodity.
On December 9, 2002, non-woven industry developed independently developed in guangdong province with a disposable medical protective clothing won the provincial drug administration approval, become a handful of domestic peers at the time, but the protective clothing fabrics are still dependent on imports, cannot independent production bring SARS prevention and control work in China at that time the difficult material.
In the first half of 2003, only domestic nonwoven spunlace and spinning capacity growth rate of more than 40%.
SARS unprecedented promoted the development of various medical gowns, masks, protective equipment, string melt-blown nonwovens and spun-bonded, melt-blown SMS composite nonwovens, SMMS gowns and masks, spun-bonded non-woven fabrics and TPU moisture permeable membrane, and various kinds of microporous breathable membrane composite products.
SARS, medical non-woven total amount 13% increase from the previous year.
At the same time, the domestic medical has realized the traditional protective clothing, surgical gowns, masks, wet paper towels can't meet the needs of antiviral and comfort, medical protection product market changes have for high-performance low-cost non-woven paving the way to popularize and apply.
The American technology production of spun-bonded melt-blown type (
SMS and SMMS)
Waterproof non-woven, outer with long silk spinning sticky, with melt-blown superfine fiber.
Grams of low weight, high strength, extension degree;
Ventilation rate is high, the hydraulic resistance is strong.
Good product uniformity, high opacity;
Spun-bonded layers composed of continuous filament, have very good breaking strength and elongation;
The spray layer is composed of continuous superfine fibre, to water, dust, bacteria, etc with good barrier effect;
Has a high water pressure resistance and good air permeability;
Good acid and alkali resistance ability;
Can produce different colors.
In the medical industry, can be used as a gown, surgical drapes, wound care, protective clothing, hats, masks, etc. ;
In the field of health, can make baby diapers and adult incontinence diapers anti sliding sideways.
Special-purpose three resistance to the SMS (for medical use
Non-woven alcohol effect grade 10 (
The ability of 100% alcohol)
, blood resistance, oil resistance effect is good;
Antistatic SMS (
Non-woven fabric antistatic effect is good, the surface resistance is less than 108 Ω, making gown, isolation gown;
Mildew antibacterial SMS (
Non-woven fabric has good antibacterial effect, which are widely used in medical, industrial and health of microorganisms demanding environment.
