Problems solved by technology

Under such production process conditions, if the fiber raw material with a fineness of about 0.45dtex is produced, it will lead to more flying flowers, more neps, and lower uniformity.
In spunlace reinforcement, conventional high-pressure jets reinforce the entangled mesh type, which will also cause the cloth surface to be hard

Embodiment 1

[0028] A preparation method of a non-woven fabric containing microfibers, the steps are as follows:

[0029] 1. Mix 6 parts by weight of superfine fibers and 4 parts by weight of Tencel fibers to obtain mixed fibers. The fiber fineness of the ultrafine fiber is 0.45dtex, which is the product of mixed wood pulp of broad-leaved forest and coniferous forest through spinning processing, and comes from Japan Omikenshi Company. The fiber fineness of the Tencel fiber is 1dtex, and it comes from Austrian Lenzing Company.

[0030] 2. Place the mixed fibers above in a closed environment with a humidity of 80% for 24 hours to raise cotton. The method of ultrasonic atomization and humidification is used to maintain the humidity of the closed environment at 80%. This step can reduce the frictional static electricity of fibers with small fineness, reduce the phenomenon of flying flowers and cotton particles in the subsequent process, and improve the uniformity of the cotton web. .

Embodiment 2

[0039] A preparation method of a non-woven fabric containing microfibers, the steps are as follows:

[0040] 1. Mix 5 parts by weight of superfine fibers and 5 parts by weight of Tencel fibers to obtain mixed fibers. Get mixed fibers. The fiber fineness of the ultrafine fiber is 0.45dtex, which is the product of mixed wood pulp of broad-leaved forest and coniferous forest through spinning processing, and comes from Japan Omikenshi Company. The fiber fineness of the Tencel fiber is 1dtex, and it comes from Austrian Lenzing Company.

[0041] 2. Put the mixed fibers above in a closed environment with a humidity of 90% for 30 hours to raise cotton. The humidity of the closed environment is maintained at 90% by means of ultrasonic atomization humidification.

[0042] 3. Using a carding machine to card the mixed fibers after raising the cotton into a web to obtain a fiber web.

[0043] Cotton feeding is carried out by weighing and feeding with weighing curtains. The rotating spe...

Abstract

The invention relates to a non-woven fabric with superfine fiber and a preparing method and application of the non-woven fabric. The preparing method includes the following steps of mixing the superfine fiber with tencel fiber to obtain mixed fiber, placing the mixed fiber in the closed environment with the humidity of 80-90% for 24-48 h, carding the fiber to obtain a fiber net, and conducting spunlace reinforcing and drying on the fiber net to obtain the non-woven fabric. The technological parameters of spunlace reinforcing include: a plurality of spunlace heads are arranged, each spunlace head is perpendicular to the plane where the fiber net is located, and the spunlace heads continuously move in the plane perpendicular to the moving direction of the fiber net in the spunlace reinforcing process. The non-woven fabric prepared through the method has a porous micro-pore fluff soft cloth surface and is high in softness, good in moisture preserving effect, large in specific surface areaand high in water-absorbing quality, little fluff and cotton are produced in the production process, and a cotton net is stable and uniform.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a non-woven fabric containing superfine fibers and a preparation method and application thereof. Background technique [0002] In the current spunlace process, viscose or modified viscose and chemical fiber raw materials are generally used, which are opened and cleaned, carded into a web, and then reinforced by a spunlace jet, then dried, wound, and cut into coils. In the whole production process, the raw materials are directly provided by the supplier without further treatment, the fineness of the raw materials is 1.2-2dtex, and the length is 30-51mm; when carding into a web, there are not too high requirements for the equipment, and the technical process is stable and mature. Under such production process conditions, if the fiber raw material with a fineness of about 0.45dtex is produced, it will lead to more flying flowers, more neps, and a decrease in uniformity. In spunlace reinforc...
