New applications of spunbond nonwovens

Since non-woven fabrics do not require the spinning and weaving processes of traditional textiles, but directly form fabrics from fibers, their development speed far exceeds that of traditional textiles, and is used in sanitation, environmental protection filtration, geotechnical construction, automobiles, artificial leather, It is widely used in packaging and clothing. According to the degree of durability, clothing is divided into two categories: durable and non-durable/disposable clothing. At present, the application of hot-rolled non-woven fabrics in clothing is mainly concentrated in the field of non-durable clothing. The application of non-woven fabrics in non-durable clothing has been very popular, such as spunlace medical protective clothing, PP disposable spunbond protective clothing and SMS medical protective clothing. At present, the development of new products in this field includes two aspects, one is the new expansion of existing materials in the field of clothing applications; the other is the development of new non-woven fabrics. Spunbond non-woven fabrics are composed of high-strength continuous filaments and occupy a large proportion in the disposable protective clothing market. The latest development is the addition of special additives or special additives in the production process of spunbond non-woven fabrics. After finishing, the product has the functions of flame retardant, antistatic, anti-radiation, hydrophobic and moisture conductive, antibacterial, and warmth. While providing various required protective functions to the human body, it can also effectively prevent harmful and dusty substances. Invasion. Another new product of spunbond non-woven fabric is SFS composite material. Two layers of spunbond fabric are compounded with the waterproof and moisture-permeable membrane in the middle. This product makes up for the lack of membrane strength and makes full use of the waterproof and barrier of the waterproof and moisture-permeable membrane. Ability to give the material waterproof and moisture permeability and barrier properties. It has the same waterproof and moisture permeability and barrier properties as SF, but SFS is more than SF with one layer of spunbond fabric, which effectively protects the waterproof and moisture-permeable membrane and makes the material safe. Higher and more functional, it is an ideal material for medical disposable protective clothing.
