可生物降解的非織造布-聚乳酸(PLA)無紡布

作者:Jennie 瀏覽: 發表時間:2023-02-17 13:41:37

PLA無紡介紹及用途

聚乳酸(PLA)是一種新型的生物降解材料,使用可再生的植物資源(如玉米)所提出的澱粉原料製成。澱粉原料經由發酵過程製成乳酸,再通過化學合成轉換成聚乳酸。其具有良好的生物可降解性,使用後能被自然界中微生物完全降解,最終生成二氧化碳和水,不汙染環境,這對保護環境非常有利,是公認的環境友好材料。

PLA is a new biodegradable material made from starch derived from renewable plant resources such as corn.Starch raw materials is fermented into polylactic acid through the fermentation process, and then through chemical synthesis,It has good biodegradability. After used, it can be completely degraded by microorganisms in nature and eventually generate carbon dioxide and water. It does not pollute the environment, and it is very beneficial to protecting the environment.


PLA/聚乳酸纖維優點


PLA/聚乳酸纖維,作為一種新型綠色環保纖維,不同於傳統的纖維素纖維和化學纖維,但同時具有這兩種纖維的優點:

PLA/ polylactic acid fiber, as a new type of green fiber, is different from the traditional cellulose fiber and chemical fiber, but has the advantages of the two kinds of fiber:

1. 填埋堆肥狀態下可100%降解成二氧化碳和水,整個PLA纖維的加工、使用過程是低能耗、環保和可循環的,有效的降低了碳排放,對環境友好。

Under the condition of landfill compost, it can be 100% degraded into carbon dioxide and water. The whole PLA fiber processing and use process is low energy consumption, environmentally friendly and recyclable, which effectively reduces carbon emissions and is environmentally friendly.

2. 天然抑菌性,PH5-6,天然弱酸性 自動平衡人體皮膚環境,抑製有害細菌繁殖,維護人體健康

Natural bacteriostasis, PH5-6, natural weak acid automatically balance human skin environment, inhibit harmful bacteria reproduction, maintain human health

3. 生物相容性,聚乳酸的單體為乳酸,是人體新陳代謝的一種產物,對人體無毒性,可以被人體完全吸收,是世界公認的環保材料。

Biocompatibility, the monomer of polylactic acid for lactic acid, is a product of human metabolism, non-toxic to the human body, can be completely absorbed by the human body, is the world recognized environmental protection material.

4. 吸濕性,極低的吸濕性能,分子表面天然疏水性,平衡含水率低,反滲低,無潮感,是衛材的理想材料。

Extremely low hydrophilic property, natural hydrophobic, low balance moisture content, low reverse osmosis, no moisture sense, is the ideal material for Hygiene products.

5. 阻燃性性能,極限氧氣指數達到26,所有纖維裏阻燃性能最好的材料。

Flame retardant performance, limit oxygen index reached 26,  one of the best materialin all the flame retardant performance fiber.

6. 容易洗滌,具有去汙性能省水省電

Easy to wash, save water and electricity.

PLA無紡布應用


PLA無紡布可以廣泛應用於醫療、衛生用無紡布(衛生巾、衛生護墊及一次性衛生用布)等、家庭裝飾用無紡布(手提袋、貼牆布、台布、床單、床罩等)、農業用無紡布(比如作物保護布、育秧布等);

PLA non-woven fabrics can be widely used in medical, sanitary non-woven fabrics (sanitary napkins, sanitary pads and disposable sanitary cloth), family decoration non-woven fabrics (handbags, wall cloth, tablecloth, bed sheets, bedspreads, etc.), agricultural non-woven fabrics (such as crop protection cloth, seedling cloth, etc.);

紡融機械

紡融機械有限公司結合PLA原材料的特點及多年紡粘無紡布的經驗積累,與西門子等國內外知名專業設備製造商合作,研發的PLA紡粘無紡布生產線具有如下特點:

Base on the characteristics of PLA raw materials and the accumulation of years of experience in spunbonded non-wovens,Spentex Machinery Co., Ltd. has developed the PLA spunbonded non-wovens production line in cooperation with well-known domestic and foreign professional equipment manufacturers such as Siemens, which has the following characteristics:


1、技術穩定:公司有3.4米幅寬展示線,長期穩定生產;

Stability: the company has a 3.4-meter wide display linefull time running, which ensures long-term stable production;


2、均勻性:采用狹縫牽伸技術,產品布面更均勻;

Uniformity: the use of slit drawing technology, fabric has good eveness and uniformity.


3、能耗省:與傳統的加工工藝比較,能耗節省20%以上。

Energy saving: compared with the traditional processing technology, energy saving more than 20%.
