Problems solved by technology

The types of cushions generally include polyurethane sponge cushions, brown cushions, spring cushions, etc., but the raw materials of existing polyurethane sponge cushions are TDI and MDI, which are petroleum by-products and are toxic. Production personnel are prone to criticism after long-term contact, and have poor air permeability; brown cushions Most of them use a lot of glue, and the volatilization of formaldehyde exceeds the standard, which is harmful to health; the spring mattress has uneven elasticity, uneven support force, loud noise during use, and poor comfort

Embodiment 1

[0019] Such as figure 1 Shown, a kind of manufacturing process of polyester / hemp fiber elastic soft cushion comprises the following steps:

[0020] (1) Opening and carding: Unpack the hemp fiber and polyester fiber raw materials, respectively perform opening and carding on the fiber opening and carding machine, loosen the compressed and entangled raw materials and remove impurities, and fully card them into single fiber state;

[0021] (2) Mixing: according to the design of the cushion, the ingredients are put into the fiber mixer for full mixing, wherein the input weight ratio of hemp fiber and polyester fiber is 1:1;

[0022] (3) sheeting: the mixture of hemp fiber and polyester fiber is spread into a sheet layer, and the thickness of the sheet layer is 2cm;

[0023] (4) Stacking: stacking multiple layers of fiber sheets to 30cm;

[0024] (5) Heat setting: put the stacked fiber layers into the bellows, first pass the hot air flow prepared by electric heating into the bell...

Embodiment 2

[0027] A kind of manufacture technology of polyester / hemp fiber elastic cushion, comprises the following steps:

[0028] (1) Opening and carding: Unpack the jute fiber and polyester fiber raw materials, respectively perform opening and carding on the fiber opening and carding machine, loosen the compressed and entangled raw materials and remove impurities, and fully card them into single fiber state;

[0029] (2) Mixing: carry out batching according to cushion design, put into fiber mixer and fully mix, wherein the input weight ratio of jute fiber and polyester fiber is 1:1;

[0030] (3) into sheet: the jute fiber and polyester fiber mixture are spread into sheet layer, and sheet layer thickness is 2cm;

[0031] (4) Stacking: stacking multiple layers of fiber sheets to 40cm;

[0032] (5) Heat setting: put the stacked fiber layers into the bellows, first pass hot air into the bellows to keep the temperature in the bellows at 200°C, so that the polyester fibers in the fiber la...

Abstract

The invention relates to a manufacture process of a polyester / bast fiber elastic cushion, comprising: unpacking bast fiber material and polyester fiber material, opening and carding respectively, adding equivalently into a fiber mixing machine, mixing well, spreading the bast fiber and polyester fiber mixture into sheet layers, and stacking the multiple fiber sheets; adding the stacked fiber layers into a bellows, introducing flows of hot air into the bellows to thermally melt the polyester fiber, introducing flows of cold air to solidify the polyester fiber in the fiber layers and to adhesive and fix the bast fibers, such that crude fiber cushion material is obtained; subjecting the crude fiber cushion material to rough edge cutting and tailoring. The polyester / bast fiber elastic cushion provided herein is nontoxic and harmless, uses no glue, is friendly to the health of production staff and human bodies, and is nonirritating; the bast fibers are of three-dimensional disorder meshed structure in the cushion, elastic support of such structure provides uniform supporting force, the structure produces no noise when compressed, and a silent service environment is provided.

Description

technical field [0001] The invention relates to the field of fiber pads, in particular to a manufacturing process of polyester / hemp fiber elastic soft pads. Background technique [0002] Due to its high comfort, cushions have become an indispensable household item in residents' homes, and are widely used in mattresses, seat cushions, etc. The types of cushions generally include polyurethane sponge cushions, brown cushions, spring cushions, etc., but the raw materials of existing polyurethane sponge cushions are TDI and MDI, which are petroleum by-products and are toxic. Production personnel are prone to criticism after long-term contact, and have poor air permeability; brown cushions Most of them use a lot of glue, and the volatilization of formaldehyde exceeds the standard, which is harmful to health; the spring mattress has uneven elasticity, uneven support force, loud noise during use, and poor comfort. [0003] Hemp fiber is a kind of natural fiber, which has advantages...
