Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preparation process of water-absorbent cotton, which solves the problem that the long-term use of cotton on the market has certain water absorption due to its own materials, but its own water absorption performance is not ideal, resulting in The use effect of cotton products cannot achieve the ideal water absorption effect

Embodiment 1

[0026] Prepare a disinfection box, an electronic scale, a foaming mold box, 2 measuring cups, and a mixer, and prepare the above materials for subsequent operations;

[0027] Weigh 80 parts and 20 parts of polyether polyol and hydrophilic polyether polyol respectively through an electronic scale, then weigh 2.8 parts of triethylenediamine and 0.33 parts of dibutyltin dilaurate, and prepare a measuring cup Weigh 41 parts of toluene diisocyanate for subsequent use, and complete the preparation of absorbent cotton

Embodiment 2

[0029] Then pour it into one of the prepared measuring cups, and then use a mixer to stir it evenly. After stirring evenly, use an electronic scale to weigh 1.1 parts of hydrophilic silicone oil and 10 parts of water-absorbing agent, and then mix the hydrophilic silicone oil and water-absorbing agent. Pour it into the measuring cup, the purity of polyether polyol is 96.53%, the purity of toluene diisocyanate is 95.83%, and the purity of hydrophilic polyether polyol is 94.67%, which makes the cotton absorption performance very ideal, and then use The mixer performs uniform stirring, and the stirring temperature is controlled between 40°C and 65°C, which can make the raw materials more fully dissolved;

[0030] Then introduce the prepared 41 parts of toluene diisocyanate into the prepared measuring cup and stir quickly for 3 to 5 seconds, mix the prepared raw materials, and stir evenly, so that the mixed raw materials have water absorption properties.

Embodiment 3

[0032] Put the hollow plant fiber cotton into the foam mold box, the content of cotton fiber in the hollow plant fiber cotton is 55%, and the biological cellulose in the hollow plant fiber cotton in S1 is 45%. Such a ratio makes the hollow plant fiber cotton The absorption performance is better, and then the raw materials in the measuring cup are introduced into the hollow plant fiber cotton, and then the hollow plant fiber cotton is sealed, and then the hollow plant fiber cotton is sealed through the mold and left for a period of time to make absorbent cotton, and then processed into Cotton products are enough, and the uniformly mixed raw materials are prepared, processed, and shaped.

Abstract

The invention provides an absorbent cotton preparation process which comprises the following steps: S1, preparing raw materials: taking hollow plant fiber cotton, polyether polyol, hydrophilic polyether polyol, hydrophilic silicone oil, toluene diisocynate, H2O, triethylene diamine, dibutyltin dilaurate and a water absorbent as raw materials, and S2, preparing a disinfection box, an electronic scale, a foaming mold box and two measuring cups, the preparation method comprises the following steps of: preparing all the materials by using an electronic scale, and respectively weighing 80 parts of polyether polyol and 20 parts of hydrophilic polyether polyol by using the electronic scale; according to the absorbent cotton preparation technology and the preparation method thereof, the water absorption performance of cotton can be improved, the water absorption performance of a manufactured cotton product is greatly improved, the use requirement for the water absorption performance of cotton products used in daily life of people is met, and the cotton product manufactured through the technology can meet the ideal water absorption performance requirement; the problem that the liquid cannot be well absorbed when the cotton product is used is prevented.

Description

technical field [0001] The invention relates to the technical field of water absorption of cotton products, in particular to a preparation process of water absorption cotton. Background technique [0002] Cotton fabrics are woven from cotton, and there are many grades. The fibers covered on the seeds of the Malvaceae plant, also known as cotton, or cotton for short, are important raw materials for the textile industry. Cotton fiber products have good moisture absorption and air permeability, and are soft. For warmth, it is mostly used for short-run jobs because it is not as durable as silk. Knife-cut stencils and photographic plates can be used for this material. Since it will scratch the network cable when cleaning, it is generally best not to reuse it. In addition , the use of this screen wastes ink more than other screens, and it will become loose after repeated use. The width of this screen is between 37 inches and 60 inches, and there are domestic and imported ones. ...
