Usage:
Spunbonds are used mainly for hygiene products such as baby and adult diapers, feminine care, and medical products such as protective apparel. Spunbonds also are used more and more in technical applications. These are used mainly for construction, coating substrates, agriculture, battery separators or even disk covers.
介紹：
紡粘無紡布：是在聚合物已被擠出、拉伸而形成連續長絲后，長絲鋪設成網，纖網再經過自身粘合、熱粘合、化學粘合或機械加固方法，使纖網變成無紡布。
SS雙紡粘無紡布：是一步法SMMS復合線上移開兩個熔噴而一步熱軋復合而成，相比單S，物理組織結構和性能都有了很大的提升。
特點
高強度、耐高溫性能好（可在150℃環境中長期使用）、耐老化、抗紫外線、延伸率高、穩定性和透氣性好、耐腐蝕、隔音、防蛀、無毒。
一步法生產低克重紡粘-熔噴-熔噴-紡粘（SMMS）復合無紡布，寬幅3.2米，國內最新先進設備，該產品廣泛應用于嬰兒紙尿褲，婦女衛生巾，成人失禁尿褲等一次性衛生材料。
1.薄型的SMS產品，因它防水透氣性，適合于衛生市場，如衛生巾、衛生護墊、嬰兒尿褲、成人失禁尿褲的防側漏邊及背襯等。
2.中等厚度的SMS產品，適合使用在醫療方面，制作外科手術服、手術包布、手術罩布、殺菌繃帶、傷口帖、膏藥貼等，也適合于工業上，用于制作工作服、防護服等。SMS產品以其良好的隔離性能，特別是經過三抗和抗靜電處理的SMS產品，更加適合作為高品質的醫療防護用品材料。
3.厚型SMS產品，廣泛用作各種氣體和液體的高效過濾材料，同時還是優良的高效吸油材料，用在工業廢水除油、海洋油污清理和工業抹布等方面。
Description:
SS nonwovens
S means spunbond, double S means there are two spunbonding machines in one line. In fact it is SMMS composite line ,when we moved the two Melteblown machines, there come out SS nonwovens. The same reason ,when we add Meltblown in the line ,it came out SMS & SMMS .
Spunbonding Process
It is similar to filament yarn production. From the chips storage, the polymer is vacuum-fed to a dosing station on top of the extruder. Inside the extruder, it becomes melted and homogenized. Passing a filter system and a spin pump, the melt is fed into the spin beam or spinnerets, which form a curtain of filaments. The filaments are cooled by means of a stream of air in a blowing area, drawn by aerodynamic forces and then transported to the downstream discharge channel. For nonwovens, instead of a further stretching process for filament yarns, the filaments are swirled around and then deposited on the wire mesh belt as a random nonwoven. This web is transferred to a bonding calender that uses heat and pressure to set such physical properties as tensile strength and elongation of the final product. After cooling, the material can be wound.
Products
Spunbonds are used mainly for hygiene products such as baby and adult diapers, feminine care, and medical products such as protective apparel. Spunbonds also are used more and more in technical applications. These are used mainly for construction, coating substrates, agriculture, battery separators or even disk covers.
Physical Properties
Endless filaments in combination with a uniform discharge guarantee low weight while retaining strength. Spunbonds have a quite high air permeability, use no chemicals, are thermobonded, and have a very good bidirectional machine direction/cross direction, and wear properties. Compared to only a few years ago, modern spunbonds are soft and comfortable, and the average weight today is 10 to 150 grams per square meter.
SMS & SMMS Composite Nonwoven
SMS Composite Nonwoven is produced by the SMMS ( spunbond – meltblown – meltblown – spunbond )composite line by one step. This line also can product SS and SMMS by adjustment the meltblown die. Our company seted up this line this year, the effective and quality is perfect.
Endless Combinations
The range of applications increases with the further development of the technologies. Since meltblowns have limited strength characteristics, they often are combined with other nonwovens. Spunbonds and other types of nonwovens also can be covered and refined with meltblowns. Today it is possible to implement production lines not only with spunbonds, but also with a meltblown component, to produce different types of nonwovens with an even more of a textile feeling
Spunlaids also may be coated; having functional for controlled absorption and, as mentioned, applied as composite material for many applications. From SMS to SSMMMSS, everything can be manufactured and implemented. This setup increases the range of applications considerably — including, just to name a few:
• hygiene;
• feminine care
• baby and adult diapers;
• medical products;
• protective masks for medical use;
• general use as a barrier layer;
• combination with other nonwovens/area-measured material;
• paper composites;
• work safety;
• protective clothing; and
• breathing masks.
