Description

Composite slurry for fabric with thermal insulation and antistatic functions, preparation method and application thereof Technical Field

[0001] The present application relates to the technical field of fabric materials, for example, a composite slurry for fabrics with thermal insulation and antistatic functions, and a preparation method and application thereof. Background Art

[0002] Down jackets are essential warmth in freezing temperatures. In recent years, the industry has been adding more functionality to fabrics to meet consumer demand for multifunctionality. For example, down jackets need to maintain excellent antistatic properties while still providing warmth in dry winter conditions. On the one hand, the industry typically uses materials such as hot stamping, graphene, and volcanic rock to enhance the thermal insulation of fabrics, but the results are limited, with a temperature rise generally around 2.5°C, and these materials lack antistatic properties. On the other hand, the industry requires additional antistatic treatment for clothing fabrics, and most methods employ a post-treatment finishing process, resulting in poor washability and antistatic fastness. Related technologies disclose methods for adding conductive yarn to fabrics, but these methods are costly to produce, less widely used, and lack inherent warmth. With increasing market demand for multifunctional down jacket fabrics, there is a significant demand for fabrics that combine warmth and antistatic properties.

[0003] Therefore, in this field, there is an urgent need to develop a fabric that has both warmth-keeping and antistatic functions, while also having the advantages of being comfortable and light.

[0004] Summary of the Invention

[0005] The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0006] This application provides a composite slurry for a fabric with thermal insulation and antistatic properties, as well as its preparation method and application. The fabric prepared in this application has significantly improved heat storage and thermal insulation capabilities, achieving a temperature increase of 4.5°C, while also retaining excellent antistatic properties.

[0007] In a first aspect, the present application provides a composite slurry for a fabric having thermal insulation and antistatic functions. Taking the total mass of the composite slurry as 100%, the composite slurry comprises the following components:

[0008] On the one hand, this application adds conductive carbon black with excellent antistatic properties, which has the advantages of low resistance and low price. Therefore, the fabric prepared from the composite slurry has good antistatic properties. On the other hand, the rare earth metal oxide component has a warming effect, which can achieve a temperature rise effect of 3-4°C. Compared with materials such as graphene and volcanic rock on the market, the rare earth metal oxide component has a better temperature rise effect. In addition, the aminocarboxylic acid complexing agent and the rare earth metal oxide complex form a conductive carbon black-rare earth metal oxide composite system, which has a synergistic effect.

[0009] This application combines antistatic materials and additives in appropriate proportions to create a composite slurry. This slurry is then applied to pre-treated polyester or nylon fabrics via rotary or flat screen printing to produce a fabric with both warmth retention and antistatic properties. The fabric produced in this application exhibits a far-infrared radiation temperature rise of up to 4.5°C, a static half-life of 1.3 seconds, and Class A antistatic performance. It also maintains good antistatic properties after 10 home washes and air-drying cycles.

[0010] In the present application, the mass percentage of the rare earth metal oxide is 15%-25%, for example, it can be 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, etc.

[0011] In the present application, by adjusting the mass percentage of rare earth metal oxides, the printed fabric has an excellent far-infrared temperature rise effect. If the content is too low, the temperature rise effect will be poor, and vice versa, it will affect the feel of the printed fabric.

[0012] In the present application, the mass percentage of the conductive carbon black is 8%-15%, for example, it can be 8%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 15%, etc.

[0015] In this application, by adjusting the mass percentage of the aminocarboxylic acid complexing agent, the conductive carbon black and the rare earth metal oxide have the best complexing effect. If the content is too low, the complexing is incomplete and the far-infrared temperature rise effect is poor. Otherwise, color spots will appear in the printed area, which will also affect the printing effect.

[0027] In one embodiment, the thickener comprises an acrylic acid copolymer.

[0034] In a third aspect, the present application provides a fabric with warmth-keeping and antistatic functions, wherein the fabric with warmth-keeping and antistatic functions is prepared from the composite pulp of the fabric with warmth-keeping and antistatic functions according to the first aspect.

[0083] Test conditions

[0084] The composite slurries provided in Examples 1 to 9 and Comparative Examples 1 to 5 were used to prepare fabrics having warmth retention and antistatic functions, and performance tests were performed. The test method is as follows:

[0085] The composite slurry is applied to the pre-treated polyester fabric by rotary screen printing to produce a fabric with thermal insulation and antistatic functions.
