1. A textile formaldehyde removal process is characterized by comprising the following steps:

padding: padding the textile containing formaldehyde into a formaldehyde remover solution, wherein the padding rate is 80-90%;

steaming and washing: rolling and conveying the padded textile into a sealed steam box at the temperature of 90-100 ℃, and performing sealed steam washing for 10-15 min;

and (3) dehydrating: rolling and conveying the steamed textile into an open width water mangle, and washing and dehydrating;

drying: rolling and conveying the dehydrated textile into a dryer for drying;

and (3) finished product: and (4) rolling and packaging the dried textile through a rolling machine to form a finished product.

2. A textile formaldehyde removal process as claimed in claim 1 wherein said formaldehyde remover solution is a sodium bisulfite solution or a sodium sulfite solution.

3. The process for removing formaldehyde from textiles according to claim 1, wherein the padding process uses one-pad or two-pad or more-pad, and the degree of penetration of the formaldehyde remover solution into the fabric is controlled by the number of padding times according to the specific conditions such as the thickness of the textiles.

4. The process for removing formaldehyde from textiles according to claim 1, wherein a steam nozzle is arranged in the steam box in the steam washing process, and high-temperature and high-pressure steam is sprayed through the steam nozzle to steam and wash the textiles.

Technical Field

The invention relates to the technical field of textile fabrics, in particular to a formaldehyde removal process for textiles.

Background

With the progress of society and the improvement of living standard, the living of materials is greatly enriched, and people have higher and higher requirements on the cloth, so that the requirements on the cloth are not only perfect in the aspects of color, quality and the like, but also have higher expectations on the cloth in other aspects. The flame-retardant cloth is a novel fireproof cloth, has the functions of flame retardance, fire prevention and the like, and is widely applied to the fields of fire fighting, buildings, furniture and the like. However, because the flame-retardant cloth is made of special raw materials and impregnated with the flame retardant, the textile generally has higher formaldehyde content. Formaldehyde is a toxic substance and has pungent smell, and long-term and low-concentration formaldehyde contact can cause headache, dizziness, hypodynamia, sensory disturbance and immunity reduction, and can cause sleepiness, hypomnesis or neurasthenia and mental depression; the harm to the respiratory system is also huge, and the long-term formaldehyde contact can cause respiratory dysfunction and hepatotoxic lesion, which are shown as hepatocyte damage, abnormal liver radiation energy and the like, and can cause cancer when the disease is serious.

Disclosure of Invention

The invention provides a formaldehyde removal process for textiles, which can greatly reduce the formaldehyde content of the textiles and reduce the harm of the textiles to human bodies.

In order to solve the technical problems, the invention provides the following technical scheme:

the invention provides a textile formaldehyde removal process, which comprises the following steps:

padding: padding the textile containing formaldehyde into a formaldehyde remover solution, wherein the padding rate is 80-90%;

steaming and washing: rolling and conveying the padded textile into a sealed steam box at the temperature of 90-100 ℃, and performing sealed steam washing for 10-15 min;

and (3) dehydrating: rolling and conveying the steamed textile into an open width water mangle, and washing and dehydrating;

drying: rolling and conveying the dehydrated textile into a dryer for drying;

and (3) finished product: and (4) rolling and packaging the dried textile through a rolling machine to form a finished product.

As a preferable technical solution of the present invention, the formaldehyde remover solution is a sodium bisulfite solution or a sodium sulfite solution.

As a preferable technical scheme of the invention, the padding process adopts one-padding-one-padding or two-padding-two-padding or multi-padding-multi-padding, and the penetration degree of the formaldehyde remover solution on the fabric is controlled by the padding times according to specific conditions such as the thickness of the fabric.

As a preferred technical scheme of the invention, in the steam-washing process, a steam nozzle is arranged in a steam box, and high-temperature and high-pressure steam is sprayed by the steam nozzle to steam and wash textiles.

The invention has the following beneficial effects: the textile containing formaldehyde is padded in the formaldehyde remover solution, the solution can react with the formaldehyde, so that the formaldehyde on the textile is effectively removed, and the formaldehyde residue on the textile is further removed through high-temperature steaming and washing and horizontal rinsing; after the process, 600ppm of formaldehyde on the textile can be reduced to be below 20ppm, so that the formaldehyde content on the textile is greatly reduced, and the harm of the textile to human bodies is reduced.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is in no way intended to limit the invention.
