可生物降解的非织造布-聚乳酸(PLA)无纺布

作者:Jennie 浏览: 发表时间:2023-02-17 13:41:37

PLA无纺介绍及用途

聚乳酸(PLA)是一种新型的生物降解材料,使用可再生的植物资源(如玉米)所提出的淀粉原料制成。淀粉原料经由发酵过程制成乳酸,再通过化学合成转换成聚乳酸。其具有良好的生物可降解性,使用后能被自然界中微生物完全降解,最终生成二氧化碳和水,不污染环境,这对保护环境非常有利,是公认的环境友好材料。

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/聚乳酸纤维优点


PLA/聚乳酸纤维,作为一种新型绿色环保纤维,不同于传统的纤维素纤维和化学纤维,但同时具有这两种纤维的优点:

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. 填埋堆肥状态下可100%降解成二氧化碳和水,整个PLA纤维的加工、使用过程是低能耗、环保和可循环的,有效的降低了碳排放,对环境友好。

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 自动平衡人体皮肤环境,抑制有害细菌繁殖,维护人体健康

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,聚乳酸的单体为乳酸,是人体新陈代谢的一种产物,对人体无毒性,可以被人体完全吸收,是世界公认的环保材料。

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. 吸湿性,极低的吸湿性能,分子表面天然疏水性,平衡含水率低,反渗低,无潮感,是卫材的理想材料。

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,极限氧气指数达到26,所有纤维里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. 容易洗涤,具有去污性能省水省电

Easy to wash, save water and electricity.

PLA无纺布应用


PLA无纺布可以广泛应用于医疗、卫生用无纺布(卫生巾、卫生护垫及一次性卫生用布)等、家庭装饰用无纺布(手提袋、贴墙布、台布、床单、床罩等)、农业用无纺布(比如作物保护布、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.);

纺融机械

纺融机械有限公司结合PLA原材料的特点及多年纺粘无纺布的经验积累,与西门子等国内外知名专业设备制造商合作,研发的PLA纺粘无纺布生产线具有如下特点:

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、技术稳定:公司有3.4米幅宽展示线,长期稳定生产;

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


2、均匀性:采用狭缝牵伸技术,产品布面更均匀;

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


3、能耗省:与传统的加工工艺比较,能耗节省20%以上。

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