Primary blended fabric

In the invention, the weight ratio of the protein fiber to the polyester fiber is 1: (0.5-1.5).

Preferably, the weight ratio of the protein fibers to the polyester fibers is 1: 1.2.

the primary blended fabric is prepared from protein fibers and polyester fibers through the processes of slivering, spinning, weaving and the like.

Preferably, the protein fiber can be selected from milk fiber or/and soybean protein fiber.

In the invention, the thickness of the fiber in the primary blended fabric is 50-100D; the warp density is 250-350 pieces/10 cm; the weft density is 300-400 pieces/10 cm.

Preferably, the thickness of the fiber in the primary blended fabric is 80D; the warp density is 300 pieces/10 cm; the weft density was 350 pieces/10 cm.

The natural protein fiber is used as a substrate raw material, has the advantages of soft hand feeling, soft luster, excellent moisture absorption, moisture conduction and heat preservation performance, good skin-friendly performance, obvious antibacterial function, and especially excellent characteristics of very soft and good moisture absorption effect. According to the invention, the protein fiber and the terylene are blended, so that the softness of the terylene fiber can be well improved, the fabric can keep the high strength and wear resistance of the terylene, and the comfortable, soft and skin-friendly performance of the fabric is improved. However, after the graphene oxide modified by the aminosiloxane is selected to modify the terylene, the phenomenon of static electricity generation in the use process of the fabric can be effectively improved, the antistatic effect is improved, and the quality and the flexibility of the fiber can be obviously improved.

The inventor thinks that the graphene oxide adopted by the invention has certain conductive performance, and the graphene oxide can conduct and disperse charges after modifying fibers, so that the accumulation of the charges is avoided, and the antistatic effect is improved. The invention uses aminosiloxane to modify graphene oxide, especially the selected N- [3- [ tri (2-methoxyethoxy) silyl ] propyl ] ethane-1, 2-diamine has special claw-shaped structural characteristics, and each claw has a plurality of oxygen atoms, and the monomer with the special structure is attached to the surface of the polyester fiber. Because the soybean protein fiber has more polar groups, the cohesive force effect of the polyester fiber on the soybean protein fiber can be improved in the blending process, the quality uniformity of the blended fiber is improved, and the product quality is improved.

Impregnation with an impregnating solution

In the invention, the prepared primary blended fabric is impregnated by the impregnating solution, and the impregnating method comprises the following steps: and (3) paving the primary blended fabric, slowly adding 0.08 wt% of protease aqueous solution, heating to 40 ℃, standing and soaking for 15min, taking out, repeatedly washing with clear water, placing in a 80 ℃ water tank for soaking for 0.5h, taking out, and drying for 5h at 90 ℃ to obtain the impregnated fabric.

Although the invention adopts the protein fiber and the polyester fiber for blending, the softness and comfort performance of the fabric can be obviously improved. However, the inventor finds that the air permeability of the fabric after blending is reduced, and the wide application of the fabric is not facilitated. The inventor soaks the fabric with special steeping liquor, so that not only can the comfortable softness of the fabric be further improved, but also the air permeability of the fabric can be effectively improved. The inventor thinks that probably, because the invention chooses to carry out special enzyme solution dipping treatment to the fabric, the protease is utilized to carry out certain degradation to the protein fiber in the fabric, so that more three-dimensional void structures can be generated on the fiber surface, the air permeability of the fabric can be improved, and simultaneously, the fabric surface has some micropore structures, namely certain micropores can be generated on the fiber surface, so that the internal structure of the fiber can be loosened to a certain degree, and the fabric is softer and more comfortable.

However, the degradation of the protein fiber by the enzyme solution is difficult to control, which easily causes the quality unevenness of the fabric and the poor control effect of the cavity. The inventor finds that the polyester fiber modified by N- [3- [ tri (2-methoxyethoxy) silyl ] propyl ] ethane-1, 2-diamine and the special arrangement for controlling the radial density and the weft density of the fabric are combined, so that the uniformity of the fabric after the impregnation of the enzyme solution is excellent, and the air permeability of the whole fabric is uniform. The inventors believe that the possible reason is that the claw-like multiple oxygen atom structure characteristic of N- [3- [ tris (2-methoxyethoxy) silyl ] propyl ] ethane-1, 2-diamine allows for greater compactness between fibers and, in concert with the areal density of the web, allows for control over the exposure of the soy protein fibers in the web without causing localized degradation of the protein fibers. The inventor surprisingly finds that when the graphene oxide is in a three-dimensional porous structure, the air permeability is increased, and the windproof property of the fabric can be further improved. The inventor thinks that the cavity formed by the protein fiber on the surface layer of the fabric and the cavity of different layers formed by the three-dimensional porous structure of the graphene oxide in the fabric can form a serpentine channel, so that the air permeability of the fabric can be improved, and the fabric can also have a windproof function in a severe environment, so that the fabric has different functions in different environments.

In a second aspect of the invention, a soft antistatic textile fabric prepared by the preparation process is provided.

The third aspect of the invention provides application of the soft anti-static textile fabric, which can be applied to the fields of clothing and home textiles.

The present invention will be specifically described below by way of examples. It should be noted that the following examples are only for illustrating the present invention and should not be construed as limiting the scope of the present invention, and that the insubstantial modifications and adaptations of the present invention by those skilled in the art based on the above disclosure are still within the scope of the present invention.

In addition, the raw materials used are commercially available from national chemical reagents, unless otherwise specified.
