Example Embodiment

[0038] Method Example 1: Hot-air forming of nonwoven fabric, that is, the web oriented in the operating direction of the equipment is first shaped by a hot air blower at a temperature of 120°C and a wind pressure of 2000 Pa, and then the non-woven fabric formed by hot air is passed through the engraved In the hot rolling mill of the pattern roller, the temperature of the engraved roller is 150°C and the total pressure of the roll width is 10MPa to form the non-woven fabric of the present invention, and the hardness of the lower engraved roller is 95HD.

Example Embodiment

[0039] Method Example 2: Hot-air forming of nonwoven fabric, that is, the web oriented in the operating direction of the equipment is first shaped by a hot air blower at a temperature of 140°C and a wind pressure of 500Pa, and then the non-woven fabric formed by hot air is passed through with engraving In the hot rolling mill of the pattern roller, the temperature of the engraving roller is at 100°C and the total pressure of the roll width is 2MPa to form the non-woven fabric of the present invention. The hardness of the lower engraving roller is 60HD.

Example Embodiment

[0040] Method Example 3: Hot-air forming of nonwoven fabric, that is, the web oriented in the operating direction of the device is first shaped by a hot air blower at a temperature of 130°C and a wind pressure of 1000 Pa, and then the non-woven fabric formed by hot air is passed through the engraved In the hot rolling mill of the pattern roller, the temperature of the engraving roller is 130°C and the total pressure of the roll width is 5MPa to form the non-woven fabric of the present invention, and the hardness of the lower engraving roller is 70HD.

Abstract

The invention discloses equipment for manufacturing novel non-woven cloth. The equipment comprises a hot rolling mill with an engraving roller. The engraving roller comprises an upper engraving roll and a lower engraving roll which are meshed mutually and a hydraulic device for controlling a relative distance between the upper engraving roll and the lower engraving roll, wherein a convex dot matrix for forming surface sunk parts of the non-woven cloth is engraved on the surface of the upper engraving roll; the hydraulic device is used for controlling movement of the lower engraving roll to realize to regulate the relative distance between the upper engraving roll and the lower engraving roll; the upper engraving roll and the lower engraving roll realize power transmission by transmission gear devices on one side of the upper engraving roll and one side of the lower engraving roll; and the other side of the upper engraving roll is externally connected with a heating device. The equipment can design and change the shape of a pattern according to consumers' requirement and market requirement to make hairiness on the surface of the hot air non-woven cloth greatly reduced and the non-woven cloth have concave-convex feeling, thereby reducing the contact area of a surface layer material and a human body and increasing comfortable feeling of the human body when the non-woven cloth is in use.

Description

technical field [0001] The invention relates to a new type of non-woven fabric production equipment. Background technique [0002] Thermally bonded nonwovens are widely used in women's hygiene products and baby diapers, usually on the top layer or second layer, which can quickly absorb body fluids (menstrual fluid, urine) and guide them as evenly as possible into the underlying layer The absorbent core, in this way, both keeps the skin dry and prevents lateral leakage of body fluids. [0003] Air-through nonwoven fabric is a kind of thermal bonding process. It is widely used in personal hygiene care products because it feels soft and fluffy and can make users feel comfortable. The hot-air nonwoven fabric adopts bi-component fibers with a side-by-side structure or a sheath-core structure. After being carded into a web, the composite fibers are heated by hot air. After the PE in the composite fibers is melted, the fibers overlap each other and become a certain strength after ...
