preparation example Construction

[0054] S1. Preparation of wool powder: First, the washed and dried waste wool fabrics were chopped in a shredder with a rotation speed of 2888rpm, and sieved from a 0.25mm mesh to obtain short wool fibers. Then, the wool staple fiber is mixed with deionized water in a certain ratio, and placed in an agitating ball mill for grinding for a certain period of time. After wet milling, wool powder with uniform particle size is collected by spray drying.

[0055] Wool fiber is a complex multi-level structure mainly composed of an outer cuticle, an inner cortex and a cytoplasmic complex connecting the two. Wool is composed of six kinds of chemical bonds (hydrophobic bond, ionic bond, hydrogen bond, isopeptide bond, intermolecular disulfide bond and intramolecular disulfide bond), and is rich in amino and carboxyl functional groups, most of these chemical bonds and functional groups exist in The cortex, and the inert and tight cuticle wraps the cortex, which to a certain extent hinder...

Embodiment 1

[0062] A method for preparing a fabric loaded with wool powder and having an odor absorption function, comprising the following steps:

[0063] S1. Preparation of wool powder: First, the washed and dried waste wool fabrics were chopped in a shredder with a rotation speed of 2888rpm, and sieved from a 0.25mm mesh to obtain short wool fibers. Then, the wool staple fiber was mixed with deionized water at a ratio of 1::10, and placed in a stirring ball mill for grinding for 6 hours. After wet grinding, the wool powder with uniform particle size is collected by spray drying method;

[0064] S2. Configuration of wool emulsion: add the wool powder prepared in step 1 to deionized water at a ratio of 10o.w.f.%, mix and treat until the pH is 4, at a temperature of 40°C and a speed of 600r Under the condition of mechanical stirring for 30 minutes under the condition of 1 / min, a uniformly dispersed wool emulsion can be prepared;

[0065] S3. Compounding of wool powder and fabric. Using...

Embodiment 2～4

[0068] Compared with Embodiment 1, Embodiments 2-4 are different in that the grinding time in step S1 is shown in Table 1, and the others are basically the same as Embodiment 1, and will not be repeated here.

[0069] The processing condition of table 1 embodiment 2~4

[0070]

[0071] see figure 1 As shown, it can be seen from Example 1 and Examples 2-4 that the adsorption rate of untreated wool fiber to ammonia is 53%. The ammonia adsorption capacity of the powder-composite fabric increases significantly when the wool is milled for 6 hours, especially when the fabric is compounded with the powder after ball milling for 6 hours, the ammonia adsorption capacity is the largest, reaching 91% after 60 minutes . This is because the increase of ball milling time promotes the increase of the specific surface area and surface energy of the wool particles, which makes it easier to absorb ammonia quickly and efficiently.

[0072] Therefore, before the fabric is treated in the pre...

Abstract

The invention belongs to the technical field of textiles, and particularly relates to a fabric loaded with wool powder and having peculiar smell adsorption function and a preparation method thereof. The method comprises the following steps: 1) preparing wool powder; 2) preparing a wool powder emulsion; and 3) loading the wool powder on the fabric by using the wool powder emulsion as a loading agent, and then drying to obtain the wool powder loaded fabric with the peculiar smell adsorption function. According to the method, the wool powder has an adsorption function, and when the wool powder is loaded on the fabric, the adsorption function can be given to the fabric; the loading method does not use chemical reagents, so that the adsorption performance of the wool powder can be prevented from being influenced.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a fabric loaded with wool powder and capable of absorbing peculiar smell and a preparation method thereof. Background technique [0002] Volatile compounds, such as volatile sulfur compounds (VOSs, such as sulfur dioxide), volatile nitrogen compounds (VONs, such as ammonia), and volatile organic compounds (VOCs, such as formaldehyde), have become major contributors to indoor air pollutants , the presence of these compounds increases the risk of acute and chronic diseases in humans. Adsorption is an effective method for removing these odorous and harmful volatile substances. The preparation of textiles with adsorption properties can not only keep the clothing smell fresh, but also help to improve the indoor air quality. [0003] In recent years, with the rapid development of fabric finishing technology, material technology and biotechnology, people have tried a vari...
