Problems solved by technology

[0003] Non-woven fabrics are usually made of fibers made of polymer materials by hot pressing, and their strength depends on the strength of the raw materials used. In the prior art, polypropylene is mostly used as raw material. Due to the general tensile strength of polypropylene, polypropylene Non-woven fabrics made of fibers are easily damaged when subjected to large forces, and due to the increasing use of non-woven fabrics, they are used in agricultural films, shoemaking, leather, mattresses, quilts, decoration, chemicals, printing, etc. , automobiles, building materials, furniture and other industries, as well as clothing interlinings, medical disposable surgical gowns, masks, caps, bed sheets, hotel disposable tablecloths, beauty, sauna and even today's fashionable gift bags, boutique bags, shopping bags, advertising bags, etc. There are applications in all fields, so the lack of strength of non-woven fabrics will greatly limit its application prospects, so there is still room for improvement

Embodiment 1

[0061] A kind of non-woven fabric, refer to figure 1 , the preparation method of non-woven fabric is as follows:

[0062] S1. Grinding polychlorotrifluoroethylene into a powder with a particle size of 10-100nm by a grinder;

[0063] S2. Add 100kg of polypropylene to the stirred tank and heat it to 160°C to melt the polypropylene, then add 30kg of polychlorotrifluoroethylene powder, 10kg of didecyldimethylammonium chloride, and 3kg of 6-caprolactone. Rotate at 80r / min, stir for 3min, and stir evenly to form a premix;

[0064] S3. The premix is ​​discharged into the extruder and the premix is ​​extruded into polypropylene fibers with a diameter of 12 μm through a spinneret;

[0065] S4. the polypropylene fiber is overwater cooled and air-dried;

[0066] S5. Cutting the polypropylene fiber to control the length to be 1m, randomly placing the polypropylene fiber with a length of 1m to form a net;

[0067] S6. Acupuncture and reinforcement of the reticular polypropylene fibers ...

Embodiment 2

[0069] The difference with embodiment 1 is:

[0070]In step S2, the addition amount of polypropylene is 100 kg, the addition amount of polychlorotrifluoroethylene powder is 37.5 kg, the addition amount of didecyl dimethyl ammonium chloride is 12.5 kg, and the addition amount of 6-caprolactone is 4 kg.

Embodiment 3

[0072] The difference with embodiment 1 is:

[0073] In step S2, the addition amount of polypropylene is 100 kg, the addition amount of polychlorotrifluoroethylene powder is 45 kg, the addition amount of didecyl dimethyl ammonium chloride is 15 kg, and the addition amount of 6-caprolactone is 5 kg.

Abstract

The invention relates to the technical field of non-woven fabrics, and aiming at the problem that the application prospect of the non-woven fabrics is greatly limited by the sufficient strength of thenon-woven fabrics, provides a non-woven fabric. The technical scheme is as follows: the non-woven fabric comprises the following components in parts by mass: 100 parts of polypropylene, 30-45 parts of polychlorotrifluoroethylene, 10-15 parts of didecyldimethylammonium chloride and 3-5 parts of 6-caprolactone. By adding the polychlorotrifluoroethylene into the polypropylene, the tensile strength of the polypropylene is effectively improved, so that the prepared non-woven fabric is relatively high in strength and not easy to crack, is better applicable to various industrial fields and is relatively wide in applicability.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. [0003] Non-woven fabrics are usually made of fibers made of polymer materials by hot pressing, and their strength depends on the strength of the raw materials used. In the prior art, polypropylene is mostly used as raw material. Due to the general tensile strength of polypropylene, polypropylene Non-woven fabrics made of fibers are easily damaged when subjected to large forces, and due to the increasing use of non-woven fabrics, they are used in agricultural films, shoemaking, leather, mattresses, quilts, decoration, chemicals, printing, etc. , automobiles, building materials, furniture and other industries, as well as clothing interlinings, medical dispos...
