The present disclosure discloses a processing and production method for machine-harvested cotton with low mechanical damage to fibers, including the steps: selecting seed cotton, cleaning the seed cotton, ginning, and finishing the ginned raw cotton. Cleaning the seed cotton includes S21, carrying out heavy-impurity cleaning by using a heavy-impurity cleaning machine; S22, carrying out foreign fiber cleaning by adopting a composite foreign fiber cleaning machine that combines winding and wind cleaning; and S23, carrying out 3-6 passes of cleaning on the seed cotton by alternately using an inclined seed cotton cleaning machine and a large-impurity seed cotton cleaning machine. Raw cotton fibers obtained by the method of the present disclosure have main quality indexes that: a fiber length is 29.8-31.2mm, a specific strength is 29.5-30.8cN/tex, a uniformity is 83.5-84.8%, a foreign-fiber content is 0.2-0.4g/t, and an impurity content is 1.6 2.0%. The quality of the processed cotton is significantly superior to that of other machine harvested cotton processing lines. Obviously, the method of the present disclosure has less mechanical damage to fibers.
