Another of Comer's enterprises was the Avondale Mills, which, with his sons' help, became one of the largest textile companies in Alabama.
The Trainer family, who had a textile business in Chester, Pennsylvania, planned to expand its business into the South by way of the new and growing industrial city of Birmingham.
It offered stock to business leaders, such as Frederick Mitchell Jackson, Sr.,
who agreed to commit $150,000 to bring the mills to Birmingham.
Jackson, president of Birmingham's Commercial Club, a forerunner of the Birmingham Area Chamber of Commerce, pledged in order "to help give employment to those badly in need of it in the young and struggling city of Birmingham."
 B.B. Comer's son, James McDonald Comer, later recalled that his father was motivated to participate in the new business by "feeling that Birmingham needed an industry which could employ women as well as men."

Accepting the businessmen's pledges of financial participation, the Trainers sought a local investor to assume presidency of the mill.
In 1897, they approached Braxton Bragg Comer.
The future governor accepted the offer, and invested $10,000 in the enterprise.
From 1897 until his death in 1927, he served as president of Avondale Mills, directing continued expansion to new sites over the years.

In 1897 Comer built the first mill in Avondale, an area that would become part of Birmingham.
 During the first year of its operation, Avondale Mills used 4,000 bales of cotton.
By 1898, Avondale Mills employed 436 laborers and generated $15,000 in profit.
By the time B.B. Comer became governor of Alabama in 1907, Avondale Mills declared $55,000 in profit and produced almost 8,000,000 yards of material.
By the turn of the century, Avondale Mills had set the course for future development.

Avondale Mills began with 30,000 spindles in the first mill in Birmingham and grew over the next thirty years to include ten mills in seven communities, with a total of 282,160 spindles.
The mills [included]:  Eva Jane, the Central, the Sally B, and the Catherine in Sylacauga; the Alexander City Cotton Mills, the Sycamore Mills, Mignon and Bevelle Mill, and the Pell City Manufacturing Company.

As cotton prices fell, poor white farmers lost their land and turned to sharecropping and tenancy; some of those were willing to give up farming and move to mill towns.
One white mill worker said, we "made good money compared with the farm."
 Another white sharecropper said, "Mebbe we ain't got much, but we sure has got more."
 And at least one white ex-farmer remembered the move with considerable enthusiasm: "Yeah!
Oh we just thought we had almost come to heaven when we got up here.
We didn't have to pick cotton, chop cotton, like that.
Just go to work and come back and nothing else to do.
And we really had it made when we come here."

Although a common practice at the time, the mills did make use of child labor.
