Problems solved by technology

[0002] At present, known pillows and pillows on pillows, cushions on seat cushions and backrests, etc., mostly use sponges, buckwheat husks, cotton or other materials with certain elasticity or softness as filling materials. The pillows made of these materials The core and pad have defects of poor elasticity, unsatisfactory air permeability and thermal insulation performance, short service life, poor comfort during use, high manufacturing cost, and not suitable for mass production

Embodiment 1

[0009] The layered polyester wadding is used as the raw material and formed into a three-dimensional structure of different geometric shapes by hot pressing.

[0010] The layered polyester wadding uses two-component polyester staple fibers with a melting point of 110°C and three-dimensional crimped hollow polyester staple fibers with a melting point of 250°C as raw materials, and the weight percentage of the two raw materials in the total weight is two sets 40% polyester staple fiber and 60% three-dimensional crimped hollow polyester staple fiber. Put the proportioned raw materials in a cotton blender and mix them in a cotton opener to comb them into layered polyester wadding.

[0011] The hot press forming process is to spread the layered polyester wadding in molds with different geometric figures, then put it into the dryer under pressure, and use double-zone hot air to penetrate and heat to 190°C, and then cool to room temperature. Release the pressure, take it out and cut ...

Embodiment 2

[0013] Spherical polyester cotton is used as raw material to form cotton tires with different geometric shapes and three-dimensional structures by hot pressing, and the entire cotton tire is a flat structure of spherical polyester cotton.

[0014] The spherical polyester cotton uses two-component polyester staple fibers with a melting point of 130°C and three-dimensional crimped hollow polyester staple fibers with a melting point of 260°C as raw materials, and the weight percentage of the two raw materials in the total weight is two-component Polyester staple fiber accounts for 30%, and three-dimensional crimped hollow polyester staple fiber accounts for 70%. Raw materials with a good proportion are placed in a cotton blender and mixed, and then placed in a cotton opener to be carded into spherical polyester cotton.

[0015] The hot pressing forming process is to spread the spherical polyester cotton in molds with different geometric shapes, then put it into the dryer under pre...

Embodiment 3

[0017] Layered polyester wadding and spherical polyester cotton are used as raw materials to form three-dimensional cotton batts with different geometric shapes by hot pressing.

[0018] The layered polyester wadding and spherical polyester cotton use bicomponent polyester staple fibers with a melting point of 150°C and three-dimensional crimped hollow polyester staple fibers with a melting point of 270°C as raw materials, and the weight of the two raw materials in the total weight is The percentage is two-component polyester staple fiber accounts for 45%, and three-dimensional crimped hollow polyester staple fiber accounts for 55%. Raw materials with a good ratio are placed in a cotton blender and mixed in a cotton opener to form layered polyester fibers. Two kinds of raw materials with different structures, wadding cotton or spherical polyester cotton.

[0019] The hot press forming process is to spread the layered polyester wadding or spherical polyester cotton in molds wit...

Abstract

A high-elasticity wadding is made of laminar polyester fibre floss and spherical polyester fibre cotton through hot pressing. Its advantages are high elasticity and air permeability and excellent insulating performance.

Description

Technical field [0001] The invention relates to a cotton tire used for pillows, throw pillows, seat cushions and backrests, in particular to a novel high-elastic cotton tire. Background technique [0002] At present, known pillows and pillows on pillows, cushions on seat cushions and backrests, etc., mostly use sponges, buckwheat husks, cotton or other materials with certain elasticity or softness as filling materials. The pillows made of these materials The core and the liner have the defects of poor elasticity, unsatisfactory air permeability and thermal insulation performance, short service life, poor comfort during use, high manufacturing cost, and are not suitable for mass production. Contents of the invention [0003] The task of the present invention is to provide a new type of high-elastic cotton tire that can replace the pillow core on the existing pillow and the pillow, the pad on the seat cushion and the backrest, and the pillow, the pillow, the seat cushion, T...
