Claims (8)

1. A deodorant fabric is characterized by comprising: a bottom layer, a fabric layer and an antibacterial deodorizing layer; the antibacterial deodorizing layer is arranged between the bottom layer and the fabric layer, and is formed by weaving antibacterial deodorizing fibers, and comprises the following components in parts by weight:
10-20 parts of acrylic fiber, 100-200 parts of swelling agent, 30-60 parts of cross-linking agent, 20-30 parts of sodium sulfide, 15-25 parts of dimethylformamide, 30-40 parts of buffering agent, 10-20 parts of deodorizing liquid and 8-12 parts of transition metal ion solution.
2. The deodorizing fabric of claim 1, wherein said swelling agent is one of methylene chloride and ethylene dichloride.
3. The deodorizing fabric of claim 1, wherein said cross-linking agent is one of ethylenediamine, propylenediamine, hexamethylenediamine, and p-phenylenediamine.
4. The deodorizing fabric according to claim 1, wherein said buffer is one of a sodium phosphate buffer and a potassium phosphate buffer.
5. The deodorizing fabric according to claim 1, wherein the deodorizing liquid is prepared by the following steps: decocting jasmine, gardenia, aglaia odorata and sweet osmanthus in water for 5-8 hours, filtering, and concentrating until the relative density is 1.18 to obtain the jasmine, gardenia, aglaia odorata and sweet osmanthus in a weight ratio of (10-20): (15-25): (5-10): 8.
6. the deodorizing fabric according to claim 1, wherein said transition metal ion solution is one of a copper sulfate solution, a silver nitrate solution, and a zinc chloride solution.
7. A method of making a deodorising block of any of claims 1 to 6, characterised in that it includes the steps of:
preparing an antibacterial deodorizing layer: placing acrylic fibers in a swelling agent for swelling, taking out the acrylic fibers for spin-drying, adding a cross-linking agent and water into the swollen acrylic fibers, heating the swollen acrylic fibers at a constant temperature, taking out the acrylic fibers, washing the swollen acrylic fibers with water, drying the swollen acrylic fibers after washing, reacting the dried acrylic fibers with sodium sulfide, dimethylformamide and a buffering agent, washing the acrylic fibers with water after the reaction is finished, drying the acrylic fibers so as to obtain chelate fibers containing a thioamide functional group, soaking the chelate fibers in a deodorizing solution, taking out the chelate fibers for drying, soaking the chelate fibers in a transition metal ion solution, taking out the chelate fibers for drying, obtaining antibacterial deodorizing fibers, and weaving the antibacterial deodorizing fibers into an antibacterial deodorizing layer;
and fixing the antibacterial deodorizing layer between the bottom layer and the fabric layer to obtain the deodorizing fabric.
8. The deodorizing fabric prepared by the method for preparing the deodorizing fabric according to claim 7.
