Embodiment 1

[0030] Weigh 100kg of triangular PET heterosexual short fibers and place them in an opener with a rotating speed of 2500 rpm for opening and dispersion to form a triangular PET fiber layer; then place the triangular PET fiber layer in a negative wind pressure of 5000Pa In the air-laid machine, a 1mm-thick special-shaped mixed fiber web is formed on a rotating web curtain with a mesh number of 50; then the special-shaped mixed fiber web is subjected to acupuncture and hot-pressing treatment. The temperature is 90° C., and the triangular PET shaped fiber non-woven fabric is prepared.

Embodiment 2

[0032] Take by weighing 90kg Y-shaped PBT short fiber, 10kg polypropylene fiber, put in the opener that rotating speed is 2500 revs / min, do opening and dispersing process, form the mixed fiber layer of Y-shaped PET fiber and polypropylene; Then The mixed fiber layer is placed in a carding machine, and a 3mm thick special-shaped mixed fiber web is formed on a rotating web curtain with a mesh number of 50; The hot-pressing temperature is 110°C, and the non-woven fabric of PET shaped fibers is prepared at a low melting point.

Embodiment 3

[0034] Weigh 80kg of pentagonal PTT short fibers, put 20kg of polylactic acid fibers in an opener with a rotating speed of 2500 rpm, and perform opening and dispersion treatment to form a mixed fiber layer of Y-shaped PBT fibers and polypropylene; then mix the fibers The layers are placed in a carding machine, and a 5mm thick special-shaped mixed fiber web is formed on a rotating web curtain with a mesh number of 50; then the special-shaped mixed fiber web is subjected to acupuncture and hot-pressing treatment. The temperature is 130°C, and the PBT special-shaped fiber nonwoven fabric is prepared at a low melting point.

Abstract

The invention belongs to the field of functional textile materials and discloses profiled fiber non-woven fabric and a manufacturing method thereof. Short profiled fiber and non-profiled fiber are taken as the base material and dispersed and mixed into a mixed fiber layer according to a certain mass ratio, and then lapping, needling or spunlace processing and hot pressing are conducted so as to obtain the profiled fiber non-woven fabric. The manufacturing method has the advantages that manufacturing technology is simple, and the hardness of the manufactured non-woven fabric is controllable. The manufactured non-woven fabric contains polymer fiber, can be widely applied to air filtration, metallurgy and the like, and has the advantages of being low in cost and wide in application range.

Description

【Technical field】 [0001] The invention belongs to the field of functional textile materials, and in particular relates to a special-shaped fiber non-woven fabric and a preparation method thereof. 【Background technique】 [0002] Shaped fiber refers to a fiber with a special cross-sectional shape spun through a certain geometric shape (non-circular) spinneret hole. Also known as "special-shaped cross-section fiber". Shaped fibers are relative to round fibers. It is extruded with a spinneret hole with a special geometric shape, so that the cross-section is a fiber with a certain geometric shape. [0003] Due to its special fiber structure, special-shaped fibers have the following characteristics compared with conventional fibers. (1) Good optical effect; (2) Large surface area, which can enhance the covering ability, reduce the transparency of the fabric, and can also improve the shortcomings of conventional round fibers that are easy to pill; (3) Excellent bulkiness and air...
