Embodiment

[0044] The manufacturing method of the hot-air nonwoven fabric for masks includes the following steps:

[0045] (1) Feeding: Put the first component and the second component of the opened cotton bale into No. 1 and No. 2 bale openers respectively, and use the electronic scale of the bale opener to separate the first and second components. The fiber is put into the opener according to the proportion stated in the formula;

[0046] (2) Opening and blending: The opening machine loosens the above-mentioned fibers in the agglomerate, and then sends the opened fibers into the blending box to fully mix the fibers;

[0047] (3) Carding: the mixed fibers are sent to a carding machine for full carding, and the fibers are carded into monofilaments and spread into a uniform web;

[0048] (4) Primary thermal consolidation: The above-mentioned fiber web is sent into a hot air oven, and the hot air flows through the hot air oven to heat the fibers. Self-adhesive reinforcement is generated between th...

Abstract

The invention provides a special hot air nonwoven fabric for face masks and a manufacturing method of the special hot air nonwoven fabric for face masks. The hot air nonwoven fabric is made of PE / PETsheath-core composite fiber of a concentric structure, wherein a sheath layer material of the PE / PET sheath-core composite fiber is PE; a core layer material is PET; the PE / PET sheath-core composite fiber comprises a first ingredient and a second ingredient; the first ingredient is PE / PET composite fiber with the thickness of 2 D, the length of 38 mm and the sheath-core ratio of 40 / 60; the secondingredient is PE / PET composite fiber with the thickness of 1.5 D, the length of 38 mm and the sheath-core ratio of 50 / 50; and the mass ratio of the first ingredient to the second ingredient is 2:8. The special hot air nonwoven fabric for face masks and the manufacturing method of the special hot air nonwoven fabric for face masks provided by the invention have the advantages that the prepared hotair nonwoven fabric has the good fluffy effect and good air permeability; when the special hot air nonwoven fabric is applied to face mask products, the wearing comfortable feeling is improved; the cooling feeling effect at the inner side of the face mask is also realized; the problems of sultry and damp feelings, allergy and the like generated when the weather is hot or the face masks are worn for a long time are solved; the manufacturing method is simple; the flexibility is high; and good development prospects are realized.

Description

Technical field [0001] The invention belongs to the technical field of non-woven fabrics, and specifically relates to a hot air non-woven fabric special for masks and a manufacturing method thereof. Background technique [0002] At present, non-woven technology is a relatively young and promising new technology in the textile industry. Non-woven fabrics have quickly penetrated into the national economy due to their unique structure, changeable technology and other advantages that traditional textiles can’t match. In various application fields, especially in the medical and health fields, nonwovens have a very broad development space. [0003] Non-woven fabric is composed of oriented or random fibers. It is a fabric that does not need to be spun and woven. It only oriented or randomly arranges the textile short fibers or filaments to form a web structure, and then uses machinery , Heat bonding or chemical reinforcement. It directly uses polymer chips, short fibers or filaments to ...
