Green edible grade softening agent for textile printing and dyeing and preparing method thereof

Abstract

The invention relates to a green edible grade softening agent for textile printing and dyeing and a preparing method thereof and belongs to the technical field of textile printing and dyeing. The preparing method of the green edible grade softening agent for textile printing and dyeing comprises the steps of melting lard oil and an stearic acid, adding a caustic soda liquid, distilled water and ethyl alcohol, keeping the temperature at 83-87 DEG C for 1.5-2 h, afterwards adding isopropyl alcohol, keeping the temperature for 25-29 min, then adding polyoxyethylene sorbitan fatty acid ester T-60, and stirring for 10-15 min, so that the softening agent is obtained. The raw materials of the green edible grade softening agent for the textile printing and dyeing are all food grade edible raw materials, and the prepared softening agent is a nontoxic, safe, environment-friendly and green edible softening agent for the textile printing and dyeing. The softening agent contains no constituents such as phenol, aldehyde, formaldehyde and azoic compounds, has good biodegradability, and does not release environmental hormones; when absorbent cotton and gauze treated by the softening agent are used for surgery of a patient, unfavorable results of 'inflamed, red and swollen and ulcerated wounds and wounds which do not heal easily' cannot be caused. The green edible grade softening agent for textile dyeing is good in softness.

Description

technical field [0001] The invention relates to a green edible grade softener for textile printing and dyeing and a preparation method thereof, belonging to the technical field of textile printing and dyeing. Background technique [0002] At present, the types of fabric softeners used in the textile printing and dyeing process include: cationic softeners, nonionic softeners, anionic softeners, quaternary ammonium salt softeners, etc.; these softeners contain phenols, aldehydes, formaldehyde, Nitrogen compounds and other ingredients have toxic side effects, are not environmentally friendly, have poor biodegradability, and release environmental hormones (for example: OPEO, APEO, benzene, formaldehyde, xylene, p-cresol, m-cresol, tetrachloroethylene, methylene chloride, eight kinds of Soluble heavy metals, ozone layer depleting substances, organotin compounds and other prohibited molecules), toxic by-products are produced in the production process, and the potential harm to the...

Problems solved by technology

[0002] At present, the types of fabric softeners used in the textile printing and dyeing process include: cationic softeners, nonionic softeners, anionic softeners, quaternary ammonium salt softeners, etc.; these softeners contain phenols, aldehydes, formaldehyde, Nitrogen compounds and other ingredients have toxic side effects, are not environmentally friendly, have poor biodegradability, and release environmental hormones (for example: OPEO, APEO, benzene, formaldehyde, xylene, p-cresol, m-cresol, tetrachloroethylene, methylene chloride, eight kinds of Soluble heavy metals, ozone layer depleting substances, organic tin compounds and other prohibited molecules), toxic by-products are produced in the production process, and the potential harm to the environment is too great

When the cotton wool and gauze treated with the above-mentioned softener are used for the operation of the patient, it is easy to cause wound inflammation, redness, swelling, ulceration, poor healing of the wound, and secondary injury to the patient.
