preparation example Construction

[0042] The invention provides a preparation method of konjac kapok fiber moisturizing wet tissue, which combines konjac glucomannan macromolecule with light industrial papermaking field, and kapok fiber and glucomannan are cross-linked to obtain a dense network similar to paper Cellulose wipes with high stability, good air permeability and high moisture retention. Including the following steps:

[0043] Pretreatment of kapok fiber: take 3 to 3.5 parts of kapok fiber in terms of parts by mass, put it into a low-temperature plasma processor, set the normal pressure treatment atmosphere to oxygen or nitrogen, and the treatment time is 30 to 60s;

[0044] Alkali treatment of kapok fiber: dissolve the pretreated kapok fiber in 96-100 parts of pure water, put it in a mixer at 1000-1500r / min and stir for 10-15 minutes until it is uniform, add 0.48-0.5 parts of anhydrous sodium carbonate Dissolve; add 0.96~1 part of konjac glucomannan after dissolving anhydrous sodium carbonate and p...

Embodiment 1

[0052] This embodiment includes the following steps:

[0053] Kapok fiber pretreatment: put 3.2 parts of kapok fiber into a low-temperature plasma treatment instrument by mass parts to carry out low-temperature plasma pretreatment; the atmosphere used in the low-temperature plasma pretreatment is nitrogen, and the time is 45s; The surface etching degree of kapok fiber after low-temperature plasma pretreatment is 70%, and the etching depth is

[0054] Preparation of mixed solution: disperse the kapok fibers pretreated by low-temperature plasma in 98 parts of water, stir evenly at a speed of 1200r / min for 10min, then add 0.48 parts of anhydrous sodium carbonate until dissolved, and then add 0.98 parts of konjac grape Mannan and 1.2 parts of glycerin were homogeneously swollen for 28 min at a rotating speed of 5000 r / min, and obtained konjac kapok fiber mixed solution after centrifugal degassing;

[0055] Inverted plate film making: spread the prepared konjac kapok fiber mixed...

Abstract

The present invention provides konjak and kapok fiber moisturizing wet tissue and a preparation method thereof; wherein low-temperature plasma pretreatment is conducted on kapok fibers, non-polymeric gas such as plasma of nitrogen and oxygen is used for conducting surface bombardment on the kapok fibers, etching is conducted on the surfaces of the kapok fibers to form pits, and the wax on the surface of the kapok fiber is effectively removed, so that the internal structure of the kapok fiber is opened, the space of the internal structure is enlarged, the surface area of the kapok fiber is increased, and konjac glucomannan can enter the kapok fiber to act and be fully combined; meanwhile, the internal structure of the kapok fiber is opened, so that groups hidden in the kapok fiber are exposed; not only are the adhesiveness and wettability of the kapok fiber improved, but also under the action of weak base, specific functional groups and a large number of carboxyl groups, hydroxyl groups and other groups in konjac glucomannan molecules form a polymer in modes of adsorption, chemical crosslinking, graft copolymerization and the like; therefore, the binding force between the kapok fiber and the konjac glucomannan is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a konjac kapok fiber moisturizing wet tissue and a preparation method thereof. Background technique [0002] In recent years, with the gradual development of society, people's living standards are also rising, people's pursuit of quality of life is constantly improving, and the consumption concept of daily necessities such as facial masks and wet wipes has changed a lot, so the demand for them The number of masks and wet wipes on the market is currently based on non-woven fabrics. [0003] Non-woven fabric is a non-woven material made of fiber mask cloth as a carrier, made of one or several different web-forming methods, and reinforced by spunlace and other processes. Most of the masks and wet wipes on the market are based on non-woven fabrics. The base fabrics of non-woven masks are mainly made of cotton, viscose, tencel, cupro fiber, and wood pulp fiber. Easy to evapo...
