The invention discloses a manufacturing process of a
sponge-free mattress. The manufacturing process comprises the following steps: (1) selecting raw materials, namely, selecting
face cloth, soybean
fiber cotton,
polyester fiber cotton and a plurality of pieces of lining cloth; (2) forming a shell fabric, namely, carrying out quilting on the
face cloth, the soybean
fiber cotton, the
polyester fiber cotton and the lining cloth by adopting a quilting
machine, thus manufacturing a composite shell fabric; (3) carrying out
cutting and
sizing, namely, according to the needed manufacturing size of the mattress,
cutting the composite shell fabric, and carrying out sewing and forming through a
sewing machine; and (4) carrying out spring manufacturing and assembling, namely, manufacturing springs through a spring
machine, and carrying out assembling for forming a net on the springs according to the size of the mattress. For the manufacturing process of the
sponge-free mattress, the
polyester fiber cotton and the soybean fiber cotton are adopted for replacing
sponge in the mattress, through the reform and innovation of the manufacturing process, the service life of the mattress is greatly prolonged, and the potential safety hazards caused to the body health by the traditional mattress adopting the sponge technology are eliminated.
