Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a processing technology for decorative spunlace nonwoven fabrics. Background Art

[0002] Semi-cross spunlace non-woven fabric is a new type of material used in the fields of medical treatment, hygiene, cleaning and wiping, beauty, home decoration, etc. It is a spunlace non-woven fabric formed by combining fiber webs in parallel and vertical directions using a semi-cross process, and then using high-pressure water needles to entangle and reinforce the fibers. The fibers used in semi-cross spunlace non-woven fabrics are generally synthetic fibers such as polyester and viscose, as well as natural fibers such as cotton and linen.

[0003] Since the fibers are crossed in direction, semi-cross spunlace nonwovens are relatively stable in strength and structure compared to straight-laid ones, and can meet higher product requirements. Existing conventional plain spunlace nonwovens require a smooth surface and good uniformity, and the pursuit of technical improvement in this field is to enrich the fabric style while ensuring product performance. Summary of the invention

[0004] The purpose of the present invention is to provide a processing technology for decorative spunlace nonwoven fabrics to solve the problems existing in the above-mentioned prior art.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides a processing technology for a decorative spunlace nonwoven fabric, and the decorative spunlace nonwoven fabric is prepared by adjusting the height and angle of a spunlace head.

[0007] Furthermore, the height adjustment range of the water jet head is 10-15 mm, and the angle adjustment range is 0-10°.

[0008] Furthermore, it also includes adjusting the single and double rows of needle plates of the spunlace head and the front and back installation of the needle plates to obtain the decorative spunlace non-woven fabric.

[0009] Furthermore, the spunlace processing technology comprises the following steps:

[0010] Raise the first, second and third water jet heads by 10 mm, the fourth and fifth water jet heads by 15 mm, and make the puncture angles of the water jet heads 90° for the first water jet head, 80° for the second water jet head, 80° for the third water jet head, 80° for the fourth water jet head, 90° for the fifth water jet head and 90° for the sixth water jet head;

[0011] Install needle plates with a hole diameter of 0.12 mm into each water jet head, among which the sixth water jet head and the fourth water jet head are single-row needle plates, and the rest are double-row needle plates. The needle plates of the sixth water jet head, the first water jet head, the second water jet head, the third water jet head and the fifth water jet head are installed on the reverse side, and the needle plate of the fourth water jet head is installed on the front side;

[0012] Adjust the water jet pressure to: 7 bar for the pre-jetting head, 50 bar for the sixth jetting head, 55 bar for the first jetting head, 60 bar for the second jetting head, 68 bar for the third jetting head, 83 bar for the fourth jetting head, and 85 bar for the fifth jetting head; perform the jelly jet forming process;

[0013] After dehumidification and shaping, the decorative spunlace nonwoven fabric is obtained.

[0014] The data adjustment error in the above processing technology is ≤10%.

[0015] Furthermore, the hole diameter of the needle plate of the pre-needling water jet head is 0.3 mm.

[0016] Furthermore, the fibers are cross-laid by a web laying machine and then transferred to a hydroentanglement machine for processing and forming.

[0017] Furthermore, the network exiting form adopted is semi-cross network exiting.

[0018] Furthermore, the processing technology also includes the following steps:

[0019] After the fiber raw materials are loosened, they are combed into a web by a carding machine, and then cross-laid by a web laying machine and transferred to a spunlace machine for processing and shaping, and then dehumidified and shaped by a dryer to obtain the decorative spunlace non-woven fabric.

[0020] The present invention also provides a decorative spunlace nonwoven fabric prepared by the above processing technology.

[0021] Conventional plain spunlace nonwoven fabrics require a smooth surface and good uniformity. Compared with traditional technologies, the production process of the present invention uses needle plates with different hole specifications and arrangements to form different water needles, adjust the height of the spunlace head by 10-15mm, and the puncture angle by 0-10° to match and reinforce each other, generating an ideal rough cloth style with clear and realistic texture effects and a strong sense of experience.

[0022] The present invention discloses the following technical effects:

[0023] The method of the invention relates to the fabric style of a semi-cross spunlace non-woven fabric, which can realize a clear imitation wood grain texture of the product, the texture effect is clear and realistic, and the product strength meets the requirements.
