Abstract
The invention discloses a high-cleaning non-irritating cotton soft towel which comprises the following raw materials in parts by weight: functional cotton fibers, PP melt blown cotton; the preparation process of the functional cotton fiber comprises the following steps: adding succinic acid modified cotton fibers and an antistatic agent into a reaction kettle, and reacting to obtain antistatic agent modified cotton fibers; the preparation method comprises the steps of magnetically stirring modified silicon dioxide, triethylamine and tetrahydrofuran in a three-neck flask, adding antistatic agent modified cotton fiber at 0 ℃, then adding 4-dimethylaminopyridine, adding N, N' -dicyclohexylcarbodiimide after reaction liquid is clarified, and reacting to obtain the functional antioxidant; and the cotton soft towel has good softness, is not easy to generate stimulation when in use, and the addition of the antistatic agent can prevent the cotton soft towel from generating electrostatic stimulation when in use.
Description
Technical Field
The invention relates to the technical field of cotton soft towels, in particular to a high-cleaning non-irritating cotton soft towel and a preparation method thereof.
Background
Chinese patent CN112853615A discloses a disposable cotton soft towel and a preparation process thereof, wherein the disposable cotton soft towel comprises wood pulp fibers and PP melt-blown cotton as raw materials, the wood pulp fibers and the PP melt-blown cotton are mixed and formed, the forming process is simple, the wood pulp fibers and the PP melt-blown cotton are mutually combined by means of self viscosity in the melting process, the good liquid absorption performance of the disposable cotton soft towel is ensured in a reasonable proportion, the mechanical performance of the disposable cotton soft towel is improved, the disposable cotton soft towel is not easy to break after being immersed, and the water absorption performance is effectively improved.
In the prior art, the cotton soft towel is relatively poor in antibacterial property when in use, so that bacteria and the like are bred, the cleanliness of the cotton soft towel is affected, and the irritation exists in the use process of the cotton soft towel material, so that the use effect of a product is affected.
Disclosure of Invention
The invention aims to provide a high-cleaning non-irritating cotton soft towel and a preparation method thereof, which solve the following technical problems: when the cotton soft towel is used, bacteria and the like are bred due to relatively poor antibacterial performance, so that the cleanliness of the cotton soft towel is affected, and the material of the cotton soft towel has irritation in the use process, so that the use effect of the product is affected.
The aim of the invention can be achieved by the following technical scheme:
the high-cleanness non-irritating cotton soft towel comprises the following raw materials in parts by weight: 50-100 parts of functional cotton fiber and 10-20 parts of PP melt blown cotton;
wherein, the preparation process of the functional cotton fiber comprises the following steps:
step 1: preparing succinic acid modified cotton fibers;
step 2: mixing 2, 2-dimethylolbutyric acid, triethylamine and tetrahydrofuran under the protection of nitrogen, adding dimethylaminopropylamine and 4-dimethylaminopyridine at 0 ℃, stirring, adding N, N' -dicyclohexylcarbodiimide, heating to 25 ℃, reacting for 3-4h, concentrating to 1/3 of the original volume, washing, extracting and steaming to obtain an intermediate 1;
mixing the intermediate 1, 4-dibromobutane and isopropanol, carrying out reflux reaction for 4-6h, and carrying out reduced pressure distillation and recrystallization after the reaction is finished to obtain an antistatic agent;
