The invention relates to a production method for a radiation-resistant fine spun fabric, which mainly comprises the following steps: dyeing and recombing wool first, and then combing the wool into colored wool tops, mixing the colored wool tops and metallic short fiber strips in spinning and mixing processes to spin into metallic yarns, and weaving, dyeing and finishing the metallic yarns to produce the radiation-resistant fine spinning fabric. Through spinning and mixing the metallic short fibers, the production method for the fabric makes the metallic fibers distributed in the fabric more evenly and improves radiation-resistant effect; the diameters of the metallic short fibers are softer than that of fine fibers, and so on, so the fabric is softer and more subtle; through the control for the weaving, dyeing and finishing processes, the fabric also has the advantages of high-grade appearance, neat hand feel, fine and pure face and excellent wearing property at the same time of having radiation-resistant function; and the fabric has most popular natural memory fold function at present simultaneously. Therefore, the fabric is suitable for producing male and female fashion coats which can show grace, luxury, romance and grade after being worn.
