The meltblown nonwoven production machine uses the special polypropylene material to plasticize and enter the meltblown die head flow channel. After being evenly distributed, it enters the spinneret. The high temperature, high speed, and high pressure hot air is sprayed out to form the meltblown nonwoven fabric, which is the middle layer of the mask. The most critical layer of filter material.
A. Production line
PP material loading---Melt extrusion---Filter---Melt pump--- Air heating compression ---Meltblown---Forming--- Electrostatic electret ---Winding
B. Meltblown nonwoven machine features
Meltblown nonwoven production line runs stably, with high output and high efficiency. The produced spunbond non-woven fabrics are evenly spread, strong, breathable, non-toxic and tasteless, and meet environmental protection standards. It is used for clothing non-woven fabrics, medical and health materials non-woven fabrics, construction non-woven fabrics, industrial use non-woven fabrics, agricultural use non-woven fabrics, disposable products for hotels and other non-woven and industrial fabrics, etc.

What kind of melt blown cloth is qualified?
Generally, samples shall be taken and sent to qualified laboratory for testing, and the qualification shall be determined according to the test results.
1、 Test basis
FZ / T 64034-2014 spunbond / melt blown / spunbond (SMS) non woven fabrics
2、 Test items
1. Appearance quality inspection: cloth appearance, hole, impurity, peculiar smell, micropore, crystal point, frit, rigid wire, unreinforced area, thin net, width deviation, color difference, joint quality.
2. Internal quality inspection: mass deviation rate per unit area, longitudinal breaking strength, transverse breaking strength, longitudinal and transverse elongation at break, hydrostatic pressure and air permeability.
3. Detection of microbial indicators: total number of bacterial colonies, total number of fungal colonies, coliform bacteria, pathogenic pyogenic bacteria.
3、 Melt blown cloth is widely used
In addition to being used as medical and health cloth, the melt blown cloth is mainly used in the production of insulation materials, filter materials, geotextiles, wrapping cloth, cement bag packaging and other products on industrial cloth, agricultural cloth is mainly used in the production of irrigation cloth, heat preservation curtain, seedling raising cloth and other products, and household decorative cloth is mainly used in the production of tablecloth, bedspread, bedspread, curtain and other products. In addition, the melt blown cloth is also used to produce sound insulation materials, space cotton, absorbent felt and other products. Therefore, understanding the detection of melt blown cloth can help us better control the quality of raw materials and guide our relevant activities.
