Problems solved by technology

[0002] As a durable consumer product, mattresses are closely related to people's health. Most mattresses are made of palm, sponge and springs, which are easy to deform and grow mites and bacteria, which endanger people's health. Therefore, people think of using hemp fiber to prepare mattresses. , can solve the antibacterial problem, but most of the hemp fiber mattresses are made of pure hemp fiber at present. Although the support layer has solved the problem of insect resistance and antibacterial, the comfort layer is still made of highly toxic sponges. make

Embodiment 1

[0023] A kind of preparation method of natural ecological N type structure cotton, comprises the following steps:

[0024] a) Pre-treatment of hemp fiber: put the hemp fiber into an airtight warehouse, add Bacillus subtilis, ferment naturally at 30°C for 5 days, dry it until the moisture regain is 14%, and pack it for later use;

[0025] b) cut the dried hemp fibers into 45 mm by a fixed-length cutting machine, and then loosen and remove foreign matter;

[0026] C) adding 30% low-melting resin and 10% curly shaped fiber to the hemp fiber after impurity removal treatment, mixing, carding, pushing and swinging to form an N-shaped web, and heating and shaping to prepare an elastic soft material.

Embodiment 2

[0028] A kind of preparation method of natural ecological N type structure cotton, comprises the following steps:

[0029] a) Pre-treatment of hemp fibers: put the hemp fibers into a closed warehouse, add Bacillus subtilis, ferment naturally at 31°C for 5.2 days, dry until the moisture regain is 10%, and pack them for later use;

[0030] b) cut the dried hemp fibers into 46 mm by a fixed-length cutting machine, and then loosen and remove foreign matter;

[0031] C) Adding 15% low-melting resin and 15% curly-shaped fiber to the hemp fiber after impurity removal treatment, mixing, carding, pushing and swinging to form an N-shaped web, and heat-baked and shaped to prepare an elastic soft material.

Embodiment 3

[0033] A kind of preparation method of natural ecological N type structure cotton, comprises the following steps:

[0034] a) Pre-treatment of hemp fiber: put the hemp fiber into an airtight warehouse, add Bacillus subtilis, ferment naturally at 32°C for 5.5 days, dry until the moisture regain is 8%, and pack it for later use;

[0035] b) cut the dried hemp fibers into 47 mm by a fixed-length cutting machine, and then loosen and remove foreign matter;

[0036] C) Add 20% low-melting resin and 20% curly-shaped fiber to the hemp fiber after impurity removal treatment, mix, card, push and swing N-type web, heat-baked and shaped to prepare an elastic soft material.

Abstract

The invention discloses a preparation method of natural ecological N-type structural cotton. The preparation method comprises the following steps: (a) pretreating bast fibers: putting the bast fibersinto a sealed bin, adding a bactericide, naturally fermenting for 5 to 6 days, drying and then packaging for later use; (b) cutting off the dried bast fibers by adopting a flying shear cutter and thenopening to remove sundries; adding low-melting-point resin and crimped and shaped fibers into the bast fibers subjected to sundry removal treatment, mixing, carding, pushing and swinging into N typeto form a net; carrying out heat baking and shaping to obtain an elastic soft material. By taking the bast fibers as main materials, the natural ecological N-type structural cotton has the advantagesof ecology, environmental protection, no toxicity and good mite-resisting and antibacterial effects; the low-melting-point resin and the crimped and shaped fibers are used to improve the elasticity, are pushed and swung into N shape to form the net, and are subjected to heat baking and shaping to obtain the elastic soft material; an arraying structure of the fibers is changed, and the weight is lighter under the condition of unchanged strength; the natural ecological N-type structural cotton has low construction price and good quality, can be applied to the fields of hemp mattresses, home decoration and automotive trim, and is suitable for mass consumption.

Description

technical field [0001] The invention relates to an elastic material, in particular to a preparation method of natural ecological N-type cotton. Background technique [0002] As a durable consumer product, mattresses are closely related to people's health. Most mattresses are made of palm, sponge and springs, which are easy to deform and grow mites and bacteria, which endanger people's health. Therefore, people think of using hemp fiber to prepare mattresses. , can solve the antibacterial problem, but most of the hemp fiber mattresses are made of pure hemp fiber at present. Although the support layer has solved the problem of insect resistance and antibacterial, the comfort layer is still made of highly toxic sponges. make. [0003] The existing market calls for healthy and cheap products, so how to prepare a healthy mattress that combines various functions, is cheap, and can lead people to a healthy path is the key to solving the current mattress problem.
