Embodiment 1
[0050] A dirt-resistant nonwoven fabric, the specific components and weights included, as shown in Table 2, by the following steps:
[0051]S1: Silicone hydroxy resin, nano-titanium dioxide, nano silica, laurin polyoxyethylene ether, silane coupling agent, sodium polycarboxylate dispersant, binder, and water are mixed with stirring, stirring speed For 800r / min, the mixture was mixed after stirring; after adding fragrant rous extract, chitosan, mixed stirring, stirring, stirred at a rate of 1000 r / min; until it was uniform to obtain a dirt-resistant coating;
[0052] S2: Even the surface of the non-woven base layer is sprayed in step S1, the coating thickness is 0.04 mm, and the coated nonwoven fabric is obtained after spraying;
[0053] S3: Put the coated nonwoven fabric in the drying box for drying, drying temperature is 35 ° C, drying time is 12h; after using a stereotype to form a nonwoven fabric, a fixed temperature 160 ° C, time 20S; after testing, the dirty non-spinning ...
Embodiment 2
[0054] Example 2: A dirt tissue nonwoven fabric, the difference from Example 1 is that the specific components and weight of the dirt-free coating are different, and the specific components and weight included are shown in Table 2.
Embodiment 3-4
[0055] Example 3-4: A dirt-free nonwoven fabric, the difference from Example 1 is that the weight ratios of the chitosan and the fragrated crust extract in the dirt-free coating are different, and the specific components and weight included. As shown in table 2.

Abstract
The invention relates to the technical field of non-woven fabrics, and particularly discloses a smudginess-resistant non-woven fabric and a preparation method thereof. The smudginess-resistant non-woven fabric comprises a non-woven fabric base layer, and the surface of the non-woven fabric base layer is coated with smudginess-resistant coating; and the smudginess-resistant coating is prepared from the following raw materials in parts by weight of 40 to 50 parts of organosilicone acrylic resin, 2 to 4 parts of vetiver grass extract, 0.8 to 2 parts of chitosan, 1 to 2 parts of nano silicon dioxide, 0.4 to 0.7 part of nano titanium dioxide, 1.8 to 2.4 parts of adhesive, 1 to 2 parts of polyoxyethylene lauryl ether, 0.8 to 1.5 parts of sodium polycarboxylate dispersant, 0.1 to 0.3 part of silane coupling agent, 1 to 2 parts of acetic acid and 80 to 90 parts of water. The preparation method of the smudginess-resistant non-woven fabric comprises the following steps of uniformly mixing raw materials of the smudginess-resistant coating to obtain the smudginess-resistant coating; uniformly coating the surface of the non-woven fabric base layer with the smudginess-resistant coating to obtain a coated non-woven fabric; and then carrying out drying, setting and inspecting to obtain a smudginess-resistant non-woven fabric finished product. The smudginess-resistant non-woven fabric has the advantage of smudginess resistance.
Description
Technical field [0001] The present application relates to the field of non-woven technology, and more particularly to a dirt-free nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric is also called nonwoven, and is made of oriented or random fibers, which is called cloth due to the appearance of the cloth and certain properties. [0003] The non-woven fabric has the advantage of short, fast production rate, high production rate, low cost, low yield and low cost production compared to traditional woven fabrics. With the development of society, the use of non-woven fabrics is also more widespread, such as gas purification, medical and health, home decoration, kitchen hygiene, etc., it is easy to contaminate the dust when contacted with dust, and it is not easy to remove; The non-woven fabric is made mainly with surface coating, that is, a coating film having dirty stain resistance is applied to the surface of the nonwoven fabric, thereby ...
