[0004]However, due to the high surface friction of metal fibers and poor crimping, it is difficult to disperse and evenly distribute the metal fibers during mixing, so that the produced There are obvious black stripes on the surface of the non-woven fabric (including the finished cloth bag), that is, the metal fiber concentration area caused by the metal fiber not being well dispersed, and the metal fiber-poor area where the local conductivity is very low and cannot meet the standard, so that the amount of metal fiber increases. and other phenomena
The appearance and conductivity of the dust bag cannot meet the standards, and the failure rate increases
The pre-blended fiber strips produced by the prior art spinning process are only used as semi-finished products of blended yarns, and are not used in the non-woven fabric manufacturing process

Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] refer to figure 2 and image 3 As shown, a kind of metal fiber-containing non-woven fabric manufacturing process disclosed by the present invention comprises the following steps:
[0028] Step 1, mixing and dispersing metal fibers and non-metal fibers evenly to form pre-mixed fibers, and using non-woven equipment (other mixing equipment) for mixing and dispersing;
[0029] Step 2, feed the premixed fiber alone or together with the non-metallic fiber into the non-woven fabric equipment, and produce non-woven fabric containing metal fiber through mixing, opening, carding, laying, and needle-punching processes. Instead of using pure metal fibers as raw materials for adding metal fibers.
[0030] The pre-mixed fiber can be produced by mixing and dispersing the metal fiber strip and at least one non-metallic fiber strip in the spinning ...

The invention discloses a metal fiber contained non-woven fabric manufacturing process which comprises the following steps: step 1: mixing and dispersing metal fiber and nonmetal fiber evenly to form premixed fiber; and step 2: independently feeding the premixed fiber or feeding the premixed fiber and nonmetal fiber into non-woven fabric equipment to prepare metal fiber contained non-woven fabric. According to the metal fiber contained non-woven fabric manufacturing process provided by the invention, metal fiber is dispersed evenly, and the anti-static and anti-flaming effects of the product are improved.
Description
technical field [0001] The invention relates to a manufacturing process of a non-woven fabric containing metal fibers. Background technique [0002] In the prior art, usually in non-woven products, such as the filter material used for bag dust removal - non-woven needle-punched felt (one of industrial non-woven fabrics), metal fibers are often added and dispersed in it to play an anti-static role. and / or flame retardant effect. [0003] The existing manufacturing process of non-woven fabrics containing metal fibers, such as figure 1 As shown, short fiber strips of pure metal fibers and / or scattered short fibers are used as one of the raw materials, and are directly mixed and fed with other non-metallic fiber raw materials in proportion to the feeding part of the non-woven fabric production line; after opening, carding, Cotton laying, acupuncture and other processes are manufactured into non-woven fabrics containing metal fibers. [0004] However, due to the high surface f...
