Manufacturing process of sponge-free mattress

Abstract

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.

Description

Technical field [0001] The invention relates to the technical field of mattress manufacturing, in particular to a foam-free mattress manufacturing process. Background technique [0002] Sponge is a plastic product produced by the glue reaction of polyurethane and TDI or MDI. TDI is toluene diisocyanate, one of the commonly used polyisocyanates. The gaseous substance of TDI can irritate the glasses and severely irritate the nose and throat after inhalation, which may cause chest tightness, which can cause asthma and even damage the bronchus. MDI is diphenylmethane diisocyanate, which volatilizes suspended particles in the air. Repeated inhalation in a poorly ventilated environment can cause respiratory allergies, irritate glasses, skin, and affect lung function! Moreover, sponges are not suitable for washing, especially machine washing, otherwise it will become fragmented and particulate, which will directly affect the use. Therefore, sponges used on mattresses are harmful to hum...

AI Technical Summary

Problems solved by technology

MDI is diphenylmethane diisocyanate, which volatilizes and suspends particles in the air. In a poorly ventilated environment, repeated inhalation can cause respiratory allergies, irritate glasses, skin, and also affect lung function! Moreover, the sponge should not be washed with water, especially not machine-washed, otherwise it will become fragmented and particulate matter, which will directly affect the use. Therefore, the use of sponges on mattresses is not good for human health and is uneconomical for users.
