Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of textile, concretely relates to a pearl ground cloth electron beam deodorization fabric. BACKGROUND

[0002] Textile fabric composed of fibers, due to its porous object shape and high molecular polymer chemical structure is conducive to microbial attachment, becomes a good parasite for microbial survival and reproduction. In addition to the harm to the human body, the parasite also pollutes the fiber, so it is necessary to develop antibacterial fabric to eliminate these adverse effects.

[0003] The prior art adds antibacterial agent in the process of manufacturing fabric, and common methods are:

[0004] 1. Fiber finishing method: add antibacterial agent to make antibacterial fiber in the spinning process, and then directly weave into antibacterial fabric.

[0005] 2. Surface coating method: the antibacterial agent is coated on the surface of the fabric.

[0006] 3. Dip padding method: the antibacterial agent is made into emulsion, and then dipped and padded, baked and finished on the fabric.

[0007] In the above method, although the fiber finishing method has the advantages of water washing and excellent performance, it has limitations on spinning varieties, and may cause defects such as fiber capacity decline, color change and hard hand feeling. And the surface coating method and dip padding method have the problem of antibacterial agent falling off, resulting in poor antibacterial effect after multiple washing of the fabric. Therefore, a durable antibacterial fabric is needed. UTILITY MODEL CONTENT

[0008] The utility model aims at providing a pearl ground cloth electron beam deodorization fabric, which grafts the antibacterial agent onto the pearl ground cloth through electron beam irradiation, so that the pearl ground cloth has durable antibacterial effect.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] A pearl ground cloth electron beam deodorization fabric, comprising a fabric layer in regular mesh shape, and an antibacterial layer grafted on the surface of the fabric layer through electron beam irradiation.

[0011] The pearl ground cloth woven by the weaving structure has honeycomb mesh, and has good air permeability. The antibacterial layer is grafted on the surface of the fabric layer through irradiation, so that the antibacterial agent is not easy to fall off before and after washing on the basis of retaining the original performance of the fabric, avoiding the antibacterial agent from transferring and penetrating to the skin surface after separating from the fiber and causing damage to normal bacteria, and making the fabric have durable antibacterial performance according to different grafted monomer types.

[0012] Further, the fabric layer is composed of continuous fabric organizations, and each fabric organization is composed of four courses of loops, the first course and the third course are both two continuous loops, the second course is a loop and a stitch, and the fourth course is a stitch and a loop.

[0013] Further, the yarn is one or more of 38S full cotton compact siro spinning, 38S cotton tencel elastic, 42S full cotton, and 48S long-staple cotton.

[0014] The fabric layer is a natural fiber or regenerated cellulose fiber, and the molecule contains a large number of hydrocarbon groups. Electron beam irradiation grafting modification is to graft monomers onto the main chain or side chain groups of the fiber polymer to form a covalent bond attached to the fiber surface through the free radicals, cations or peroxides formed by the fiber molecules under irradiation.

[0015] Further, the antibacterial layer is a cationic antibacterial agent layer, and the cationic antibacterial agent layer is irradiated and grafted with the fabric layer, and the surface of the fabric layer is connected with the cationic antibacterial agent layer through a covalent bond.

[0016] The cationic antibacterial agent is connected with the fabric layer through irradiation to form a covalent bond, so that the cationic antibacterial agent is more durable on the fabric layer. The membranes of bacteria, fungi, enveloped viruses and other microorganisms all have negative charges. By grafting the cationic antibacterial agent with cationic functional groups on the textile through covalent bond, electrostatic adsorption occurs with the microorganisms, and after adsorption, the lipophilic part contained in the grafted monomers can insert into the envelope, thereby destroying the envelope and achieving the purpose of eliminating microorganisms.

[0017] Further, the cationic antibacterial agent includes quaternary ammonium salt antibacterial agent and guanidine antibacterial agent.

[0018] In addition to good antibacterial performance, the cationic antibacterial agent can also reduce the concentration of odor chemical molecules and has certain deodorizing effect.

[0019] Further, the deodorizing layer is composed of a deodorizing agent attached to the surface of the fabric layer.

[0020] After the fabric is irradiated and grafted, the deodorizing agent is attached to the surface of the fabric layer by surface coating method or padding method to improve the deodorizing effect of the pique fabric.

[0021] Further, the deodorizing agent includes zinc oxide deodorizing agent.

[0022] Further, the yarn twist is 850T / M.

[0023] Further, the fabric layer is dyed and then irradiated by electron beam.

[0024] The fabric is dyed first and then irradiated to avoid affecting the dyeing effect after irradiation grafting.

[0025] By adopting the above technical solution, this utility model has the following beneficial effects:

[0026] The pique fabric using this woven structure has a honeycomb mesh, which provides good breathability.

[0027] Antibacterial agents are grafted onto the surface of the fabric layer through irradiation, thereby preserving the original properties of the fabric while making the antibacterial agents less likely to fall off before and after washing. This prevents the antibacterial agents from transferring and penetrating to the skin surface after detaching from the fibers, and from damaging normal bacteria. Depending on the type of grafted monomer, the fabric has long-lasting antibacterial properties.

[0028] The fabric layer is made of natural fiber or regenerated cellulose fiber, which contains a large number of hydrocarbon groups in its molecules. Electron beam irradiation grafting modification is achieved by using free radicals, cations or peroxides formed by fiber molecules under irradiation to graft monomers onto the main chain or side chain groups of the fiber polymer to form covalent bonds that adhere to the fiber surface.

[0029] After the fabric is irradiated and grafted, the deodorizing agent is then attached to the surface of the fabric layer by surface coating or padding to improve the deodorizing effect of the pique fabric. Attached Figure Description

[0034] The antibacterial layer 2 is grafted with a cationic antibacterial agent by electron beam irradiation, so that one end of the antibacterial layer 2 is covalently connected to the fabric layer 1. The cationic functional groups at the other end of the antibacterial layer 1 are positively charged, which electrostatically adsorb and kill the negatively charged microorganisms, thus achieving an antibacterial effect.
