Problems solved by technology

However, for polypropylene nonwovens with low tensile strength itself, adding too much flame retardant will undoubtedly further reduce its tensile strength, thereby affecting its protective effect.

Embodiment 1

[0042] The process flow of this example, such as figure 1 As shown, first prepare PP spunbonded nonwoven fabric, and mix polypropylene, magnesium hydroxide, aluminum hydroxide, and melamine-wrapped ammonium polyphosphate with a melt index of 38g / 10min in a weight ratio of 60:10:10:20. Raw materials, produced according to the polypropylene spunbond process, the grammage is 20g / m 2 Spun-bonded nonwoven fabric; zinc borate and polypropylene chips with a melt index of 1500g / 10min are mixed in a weight ratio of 10:90, and the production weight is 10g / m 2 PP melt-blown nonwoven fabric; then produce and process according to the process of melt-blown non-woven fabric, lay the melt-blown fiber web on the pre-produced spun-bonded non-woven fabric, and bond the two layers of non-woven fabric through a rolling mill , to make a SM nonwoven fabric layer; the bonded SM nonwoven fabric layer and the carded ES doped nonwoven fabric layer are cross-laid, and after cross-lapping, they enter th...

Embodiment 2

[0045] The process flow of this example is the same as that of Example 1, wherein the melt index of polypropylene for preparing PP spunbonded nonwovens is 38g / 10min, and the weight of ammonium polyphosphate wrapped by polypropylene, magnesium hydroxide, aluminum hydroxide, and melamine The ratio is 65:10:10:15, and the production weight is 20g / m 2 PP spunbond nonwoven fabric; PP melt blown nonwoven composition and preparation method are the same as embodiment one; In the ES doped nonwoven fabric layer carded into the net, the fineness of polyester fiber and ES fiber are respectively 9D and 4D, the mixing ratio of the three fibers remains unchanged; the hot-air drying oven for hot-air bonding and composite consolidation after cross-lapping is set at a hot-air temperature of 105°C. Other unmentioned parts are the same as the first embodiment.

[0046] After testing, the nonwoven material for industrial protective clothing prepared in this example has good tensile strength, and ...

Abstract

The invention discloses an industrial protection non-woven material and a manufacturing method of the industrial protection non-woven material. The industrial protection non-woven material comprises a PP spunbond non-woven fabric layer, an ES-mixed non-woven fabric layer and a PP melt-blown non-woven fabric layer sandwiched between the PP spunbond non-woven fabric layer and the ES-mixed non-woven fabric layer. Fire retardant mixtures of a first component are added to the PP spunbond non-woven fabric layer, and fire retardants of second components of different types are added to the PP melt-blown non-woven fabric layer. Mixed fibers of ES fibers, polyester fibers and viscose fibers are combed into a net to form the ES-mixed non-woven fabric layer. The industrial protection non-woven material has the moisture percentage similar to the moisture percentage of a human body, good gas permeability and soft and fluffy hand feelings, is comfortable to wear, has high tension stress and morphological stability in all directions, protects the structure of the melt-blown non-woven fabric layer and has the good inflaming retarding characteristic and the environment protection effect, and a guarantee is provided for the protection performance of the industrial protection non-woven material.

Description

technical field [0001] The application relates to the field of nonwoven materials, in particular to an industrial protective nonwoven material and a preparation method thereof. Background technique [0002] With the development of the chemical industry, more and more toxic chemicals have appeared one after another. During the production, storage, transportation and use of such chemicals, leakage or accidents may occur, endangering human health and even life. It is required that the fabrics for industrial protective clothing must have good liquid and solid barrier properties. However, protective materials made of traditional textiles have poor dust resistance and acid and alkali resistance, and cannot well block chemical, physical, and biological harmful substances. Although the film-coated nonwoven materials introduced in recent years have overcome the above two problems, they are not breathable, have poor softness, low moisture content, poor wearing comfort, poor moisture ...
