Problems solved by technology

[0005] Although the existing anti-cross-dyeing laundry sheets have certain anti-cross-dyeing and laundry functions, on the one hand, their anti-cross-dyeing and laundry functions need to be further strengthened; Adhesion with the outer packaging will cause a certain amount of waste and inconvenience to use. Moreover, laundry tablets generally need to be fed manually, which will cause inconvenience to users during specific use and cannot realize intelligent life.

Embodiment 1

[0042] refer to figure 1 , figure 2 , an anti-cross-dyeing laundry sheet, the laundry sheet is a product in the shape of a compressed towel, the laundry sheet 1 includes a color-absorbing layer 2 and a laundry layer 3 arranged inside the color-absorbing layer, and the color-absorbing layer includes a cationic modification permanent spunlace non-woven fabric, the fiber composition of the spunlace non-woven fabric is a mixture of viscose fiber and polypropylene fiber in a certain proportion, the viscose fiber is a cationic modified fiber, the viscose fiber and polypropylene fiber The mass ratio is 3:1; the viscose fiber is a fiber material regenerated from wood pulp or cotton pulp, and the laundry layer 3 is arranged on the color-absorbing layer 2 by one-side coating.

[0043] In parts by weight, the laundry ingredients of the laundry layer are: 0.05-0.2 parts of EDTA-2NA, 0.05-0.2 parts of Cathone, 8-14 parts of sodium dodecylbenzenesulfonate, 6-10 parts of AOS, 3 parts of LA...

Embodiment 2

[0045] refer to figure 1 , image 3 , an anti-cross-staining laundry sheet, and others are as described in Example 1, the inside of the laundry layer 3 is laid with an active enzyme layer 4, which can further improve the washing effect.

Embodiment 3

[0047] A preparation method of anti-cross-dyeing laundry sheet, using organically active ion modifier as raw material, carrying out cationic modification on spunlace non-woven fabric, and then applying laundry ingredients (applying detergent) to make anti-cross-staining Laundry tablets, the process is as follows:

[0048] Spunlaced non-woven fabric processing→corona treatment→ion modification→applying detergent→drying slices

[0049] Specifically include the following steps:

[0050] (1) After mixing viscose fiber and polypropylene fiber in proportion, they are opened, mixed, carded, laid,

[0051] The process of high-pressure spunlace entanglement, drying, and rolling makes the fibers into spunlace non-woven fabrics that are tightly entangled and have a microporous structure;

[0052] The optimization of the mass ratio of viscose fiber to polypropylene fiber is shown in Table 1:

[0053] Table 1

[0054]

[0055] (2) Using spunlace non-woven fabric as the basic materia...

Abstract

The invention relates to an anti-cross color dyeing laundry sheet, a preparation method and a use method thereof. The laundry sheet is a compressed towel shaped product, and consists of a color adsorption layer and a laundry layer disposed on the inner side of the color adsorption layer, the color adsorption layer includes cation modified spunlaced nonwoven fabric, the fiber composition of the spunlaced nonwoven fabric is formed by mixing of viscose fiber and polypropylene fiber in certain proportion, the viscose fiber is cation modified fiber, and the viscose fiber and polypropylene fiber arein a mass ratio of 2-4:1. Through single side spraying of the laundry layer and stamping into a compressed towel shape, the product has relatively dry and clean surface and does not stick to hands, and while good laundry and anti-cross color effects are ensured, adhesion of the laundry sheet to outer packing is well avoided. The laundry sheet provided by the invention also has the advantages of strong adsorption capacity, good laundry effect, convenient carrying, cross color dyeing prevention and the like, also can meet users' demand for intelligent home appliances, provides convenience for laundry, and can improve people's quality of life.

Description

technical field [0001] The invention belongs to the technical field of fabric washing products, and in particular relates to an anti-cross-dyeing laundry sheet and its preparation method and use method. Background technique [0002] At present, the washing of people's family clothes generally uses soap or washing powder or washing liquid, and generally uses washing powder or washing liquid during machine washing. In recent years, laundry tablets have appeared on the market, that is, after optimizing the formula of laundry detergent, it will be made into a flake-shaped solid through a certain process, and it will dissolve in water. It is characterized by portability, environmental protection, no phosphorus, and no fluorescent whitening agent. , the pH value is controlled in the neutral range, mild and does not hurt the hands. This product has been loved by the younger generation since it was launched on the market. [0003] In the process of washing clothes, we often encount...
