Description
Technical field
The present invention relates to a kind of manufacturing process of mattress, more particularly to a kind of production technology of environmentally friendly dermatine.
Background technology
Mattress be in order to ensure consumer secure good health and comfortably sleep and use it is a kind of between human body and bed it
Between article, mattress material is various, different materials make mattress can give people to bring different sleeper effects.The trip of modern field
It is more to swim chance, there is an urgent need to portable, easy cleaning, the mattress of environmental-friendly and comfortable.
Artificial leather is a kind of outward appearance, feel like leather and can replace its plastic products that use.Generally using fabric as base,
Coating synthetic resin and the addition of various plastics are made.Last century the eighties, expensive fur clothing cladding common people can not consume, should
The market demand, the artificial leather of counterfeit leather once came into vogue, and were widely used in clothing, system bag.The people of so counterfeit leather
Fabricate-leather clothes, bag are once full of street corner, meet the hope that people wear Pi Daipi.Compared with leather, artificial leather is easy to aging
Abrasion, because producing harm to health of human body containing a large amount of chemical raw materials, and also it is gradual because not being durable with the clothing bag of its making
Market is lost, until being substituted by other raw materials.For natural leather, it emphasizes the synthesis performance of " material ".It is with day
The institutional framework of right leather is target, and with flexible high polymer material (such as polyurethane) impregnated fiber layer, (such as polyamide is fine
Dimension, polyester fiber etc.), fibrous layer imitates the random 3-D solid structure of natural leather lamina reticularis, elastic polymer material shape
Into the film with continuous microcellular structure, the composite that a kind of structure and performance all exactly like natural leather is made.
With the continuous development of superfine fiber chemical leather industry, its application field also constantly expands, although its many side
Face is all excellent than natural leather (such as mechanical performance), but its sanitation performance, dyeability still suffer from compared with natural leather
Larger gap.It is reported that the crust leather vapor pervious amount of natural leather is 800mg/ (10cm224h) left and right, and superfine fibre synthesizes
The vapor pervious amount of leather is only 400mg/ (10cm224h) left and right.In fact, superfine fiber chemical leather has been current all conjunctions
The main reason for water vapour permeability is optimal among finished leather, and it is with natural leather sanitation performance difference in natural leather collagen it is fine
Hydrophilic radical in dimension is more than the hydrophilic radical in superfine fiber chemical leather.
Prior art someone is modified using microorganism, makes more ventilative artificial leather, but microbial fermentation is not easy stabilization.
The present inventor is in long-term production practices, it was found that a kind of production technology of environment friendly mattress, can obtain comfortably,
Ventilative, good hand touch, the emulsion layer that wear-resisting environment-friendlyartificial artificial leather wraps up one layer 2-3 centimetres makes mattress, very portable, easy to clean and
Comfortably.
The content of the invention
The invention aims to solve the deficiencies in the prior art, there is provided a kind of production technology of environment friendly mattress, obtain
Comfortably, breathe freely, good hand touch, wear-resisting environment-friendlyartificial artificial leather, the emulsion layer of one layer 2-3 centimetres of parcel makes mattress, very portable, easily
Clear up and comfortable.
