Chemical Properties of Field-Weathered Cotton

some specific changes in needle design should reduce needle temperatures. The following examples are given : a. The holes should be punched in the needle shank above the eye to increase surface area-to-mass ratio and decrease heat stored by the needle. This would also make cooling during sewing more efficient and make cooling by compressed air more effective. b. The needle shank should be grooved to increase
