Meltblown non-woven fabric is called the "heart" of medical surgical masks and N95 masks in the industry. It is a filter layer in the middle of masks. The production of masks requires the use of meltblown nonwovens. The gap in the mask is huge, so the gap in the meltblown nonwoven will also be larger!

According to the statistics of China Industrial Textile Industry Association, the production technology of China's nonwovens industry is mainly spunbond. In 2018, the output of spunbond nonwovens was 2.971 million tons, accounting for 50% of the total output of nonwovens. It is mainly used in sanitary materials and other fields; however, there are not many manufacturers of meltblown nonwovens. The process accounted for only 0.9%, and the domestic output of meltblown nonwovens was 53,500 tons / year. These meltblown fabrics were used not only for masks, but also for environmental protection materials, clothing materials, battery separator materials, and wiping materials.

According to the current data, the national meltblown nonwoven production is less than 100,000 tons per year. Meltblown non-woven fabric is called the "heart" of medical surgical masks and N95 masks in the industry. It is a filter layer in the middle of masks. It has good filterability, shielding, heat insulation and oil absorption. It is an important raw material for the production of masks. A mask only needs a few grams of meltblown, and adding a meltblown production line usually takes one year.

Under the epidemic situation, the demand for masks increased significantly. According to the data of the Fourth National Economic Census, the total employment of domestic legal entities and self-employed households is as high as 533 million people. Based on one mask per person per day, at least 533 million masks are required per day. According to data from the Ministry of Industry and Information Technology in February this year, the current daily production capacity of domestic masks is 20 million. The gap in masks is huge, and many companies have begun to produce masks across borders. According to the data of Tian's Eye Examination, based on the changes in industrial and commercial registration information, from January 1 to February 7, 2020, more than 3,000 companies across the country have added "masks, protective clothing, disinfectants, thermometers, medical equipment, etc." Equipment "and other services. The production of masks requires the use of meltblown nonwovens. The gap in the mask is huge, so the gap in the meltblown nonwoven will also be larger!

Under such circumstances, the country has launched a number of source companies to start production and increase production capacity. However, at present, it seems that it is not optimistic in the face of the textile platform and the circle of textile people seeking melt-blown non-woven fabrics. China's production speed is facing unprecedented challenges in this pneumonia! But I believe that in the face of improving conditions, I believe that everything will be okay.

Meltblown nonwoven

Meltblown cloth is mainly made of polypropylene, and the fiber diameter can reach 1 ~ 5 microns. There are many voids, fluffy structure, and good anti-wrinkle ability. These ultrafine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption. . Can be used in the fields of air, liquid filter materials, insulation materials, absorbent materials, mask materials, thermal insulation materials, oil-absorbing materials, and wiping cloths.

The process of meltblown non-woven fabric: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming a net --- strengthening the cloth.

Application range

(1) Medical and hygiene cloths: surgical gowns, protective clothing, disinfection cloths, masks, diapers, women's sanitary napkins, etc .;

(2) Fabrics for home decoration: wall coverings, tablecloths, sheets, bedspreads, etc .;

(3) Clothing fabrics: linings, adhesive linings, flakes, styling cotton, various synthetic leather backings, etc .;

(4) Industrial fabrics: filter materials, insulation materials, cement bags, geotextiles, cladding fabrics, etc .;

(5) Agricultural cloths: crop protection cloths, seedling cloths, irrigation cloths, insulation curtains, etc .;

(6) Others: space cotton, thermal insulation materials, linoleum, smoke filters, tea bags, etc.

Meltblown cloth can be called the "heart" of surgical masks and N95 masks.

Medical surgical masks and N95 masks generally use a multi-layer structure, referred to as the SMS structure: the inner and outer sides are a single layer of spunbond (S); the middle is a meltblown layer (M), which is generally divided into single or multiple layers.

Plane masks are usually PP spunbond + meltblown + PP spunbond. You can also use short fibers to improve skin feel. Three-dimensional cup-shaped masks are usually PET polyester needle-punched cotton + melt-blown + needle-punched cotton or PP spunbond. Among them, the outer layer is a non-woven fabric with a waterproof treatment, which is mainly used to isolate the droplets sprayed by patients; the middle melt-blown layer is a specially-treated melt-blown non-woven fabric, which has good filterability and shielding , Thermal insulation and oil absorption, are important raw materials for the production of masks; the inner layer is ordinary non-woven fabric.

Although the spunbond layer (S) and meltblown layer (M) of the mask are both non-woven fabrics and the raw materials are polypropylene, the manufacturing process is different.

Among them, the fiber diameter of the spunbond layer on the inside and outside is relatively thick, about 20 microns; the fiber diameter of the meltblown layer in the middle is only 2 microns, and is made of a polypropylene material called high-melt fat fiber.

Dongyang Laichi Environmental Protection Technology Co., Ltd. has always been committed to the research, development and production of medical non-woven fabrics, spunbond non-woven fabrics, elastic non-woven fabrics, and non-woven products. The elastic non-woven fabrics produced by the company can be replaced, recycled and reused, so they can no longer worry about health problems.
