Problems solved by technology

Due to its unique processing characteristics, the products produced have the characteristics of softness, drape, comfort, strength, and sanitation, which make the products widely used in medical and health care, packaging, decoration, wiping and other fields, but when the products are used in the wiping field Easy to shed hair and chip, poor stiffness
[0003] In the field of wiping in the textile industry, in order to prevent lint and lint, non-woven fabrics are usually used for double-sided printing. Double-sided printing generally requires two printing processes, that is, after printing on one side, mirror printing on the other side. The process is complicated, the efficiency is low, the cost is high, and the double printing is easy to cause ghosting and dislocation of the patterns on both sides. Spunlace nonwovens cannot be printed on both sides at the same time.

Embodiment 1

[0028] Example 1, the base fabric is a parallel-laid spunlace nonwoven with a ratio of 5:5 of viscose polyester as an example to illustrate, and the specification of the parallel-laid spunlace nonwoven is 50gsm.

[0029] As shown in the figure, the equipment used for the production method of printing spunlace nonwoven fabrics includes a dipping device, a pressing device and a printing device. The dipping device is a dipping tank 3 and three guide rollers 2. The dipping device includes A dip tank 3 and three guide rollers 2, the dip tank 3 is a tank-shaped container, the three guide rollers 2 are arranged in the dip tank 3, the dip tank 3 contains a slurry solution, and one of the guide rollers 2 Immerse into the slurry to increase the residence time of the non-woven fabric in the slurry tank 3 to ensure that the slurry can evenly penetrate the spunlace non-woven fabric. The slurry includes a binder and a defoamer, and the solvent is softened water. The foaming agent mainly rem...

Embodiment 2

[0043]Example 2, the base cloth is a parallel-laid spunlace cloth of viscose fiber, the specification is 45gsm, the concentration of the adhesive in the slurry in the immersion tank 3 is 8%, the concentration of the defoamer is 0.4%, the above The pressure between the squeeze roller 5 and the lower squeeze roller 6 is 0.5Mpa, the concentration of the adhesive in the paste in the printing roller 8 is 10%, the concentration of the color paste is 0.8%, and the concentration of the thickener is 5% , the concentration of the defoaming agent is 0.4%, the pressure between the rubber roller 7 and the printing roller 8 is 0.6Mpa, and in the drying process, the spunlace nonwoven fabric after printing the pattern is heated to a temperature of 80 ° C, and the duration is 30-60S, then heat up to 160℃, the duration is 30-60S, and then dry with a rotary screen at a temperature of 130℃, the production speed is 25m / min, and then the finished printing spunlace is obtained through the testing pro...

Embodiment 3

[0048] Example 3, the base cloth is a parallel-laid spunlace cloth with polyester fibers, the specification is 50gsm, the concentration of the binder in the slurry in the immersion tank 3 is 9.5%, the concentration of the defoamer is 0.5%, and the upper extrusion The pressure between the pressing roller 5 and the lower pressing roller 6 is 0.5Mpa, the concentration of the binder in the paste in the printing roller 8 is 10%, the concentration of the color paste is 0.8%, and the concentration of the thickener is 5%. The concentration of the defoaming agent is 0.4%, the pressure between the rubber roller 7 and the printing roller 8 is 0.6Mpa, and in the drying process, the spunlace nonwoven fabric after printing the pattern is heated to a temperature of 80 ° C, and the duration is 30 -60S, then heat up to 160℃, the duration is 30-60S, and then dry with a rotary screen at a temperature of 130℃, the production speed is 20m / min, and then the finished printing spunlace non-woven fabri...

Abstract

The invention relates to equipment for producing a printed spunlaced non-woven fabric. The equipment comprises an immersing device, a squeezing machine and a printing device. The immersing device comprises an immersing tank and a guide roll, wherein the guide roll is arranged in the immersing tank; slurry is contained in the immersing tank; and the guide roll is immersed in the slurry. The squeezing machine comprises an upper squeezing roll and a lower squeezing roll, wherein the central axes of the upper squeezing roll and the lower squeezing roll are parallel and the peripheries of the upper squeezing roll and the lower squeezing roll are tangential to each other. The printing device comprises a rubber roll and a printing roll which are arranged up and down; the central axes of the rubber roll and the printing roll are parallel; the peripheries of the rubber roll and the printing roll are tangential to each other; patterns are carved on the periphery of the printing roll; a slurry tank is arranged below the printing roll; the slurry is contained in the slurry tank; and a part of the printing roll is immersed in the slurry. After flowing through the immersing device, excessive slurry is discharged; and through the squeezing machine, the two surfaces of the spunlaced non-woven fabric are printed. The conformity of the patterns on the two surfaces is improved and the malposition of the patterns is avoided.

Description

technical field [0001] The invention relates to a production equipment for spunlace non-woven fabrics, in particular to a device for producing printed spunlace non-woven fabrics, which belongs to the technical field of textiles. Background technique [0002] At present, spunlace nonwovens are generally made from a certain proportion of polyester staple fibers and viscose staple fibers through a series of processes such as mixing, opening, carding, cross-laying, spunlacing, and drying. It is a kind of non-woven material that penetrates the fiber web through the high-pressure water needle, and has a certain strength and thickness through the mutual entanglement between the fibers of the fiber web. , cross-laid, semi-cross-laid and other laying methods. Due to its unique processing characteristics, the produced products have the characteristics of softness, drape, comfort, strength, hygiene, etc., so that the products are widely used in medical hygiene, packaging, decoration, ...
