Abstract
The invention provides a brand new manufacturing concept and a method of non-woven fabrics with internal thermal bonding, which utilize a porous heat-resistant plastic hose or a stainless steel pipe to release steam in a fiber net, and heat the fiber from the inside to melt and bond the fiber, thereby improving the steam utilization rate, reducing the energy consumption, simultaneously having uniform heating effect, improving the finished fabric strength, reducing the cost, having more stable structure and good air permeability, and improving the finished fabric quality.
Description
Technical field
The present invention relates to a kind of manufacture method of nonwoven fabric, especially internally the manufacture method of the nonwoven fabric of hot adhesion.
Background technology
When nonwoven fabric is reinforced, hot adhesion is one of most common form, and characteristics are to utilize into measuring fiber, or joins the hot melting cohesion that a part of fiber had in the non-woven fabrics fiber net, heat by various forms, as hot rolling mode, infrared mode and hot blast mode etc., make heat adhesiveness fiber partial melting bonding, add the hot path ecto-entad and extend, as consuming big energy, can cause external heat abundant, and the not enough situation of inner heating consume lot of energy.
Summary of the invention
The purpose of this invention is to provide a kind of manufacture method that heats fully, saves the nonwoven cloth with thermal caking inside of energy.
For realizing that technical scheme provided by the present invention is:
For becoming the higher nonwoven fabric of cloth thickness, at first select for use diameter at 5-10mm, the heat resistant plastice flexible pipe of wall thickness 0.8-1.5mm or stainless steel tube are as " framework " of nonwoven fabric inside, pipe hollow, two ends link to each other with steam output main pipe with admission respectively, several apertures are arranged on the surface of pipe, hole diameter 1-2.5mm, this framework just temporarily can not stayed in the cloth in nonwoven fabric inside, from nonwoven fabric, spin off smoothly for making at Cheng Buqian, flexible pipe will wrap up with water-soluble paraffin earlier before inserting nonwoven fabric, paraffin such as the water-soluble paraffin of BZW-2 etc., the process of parcel is carried out in the fusion tank of paraffin, with paraffin fusion under 75-93 ℃ temperature, flexible pipe is immersed in that 3-5 takes out second in the paraffin tank, naturally cooling forms and coats, when fleece-laying, the density of the top plastic flexible pipe that has coated with paraffin according to 3-5 root/10cm is arranged between the two layer web, fleece-laying finishes the steam of the end feeding 0.1-0.15MPa of back pipeline, the melted paraffin wax pipeline is extracted out simultaneously, and pressurize with roller rapidly, flush away paraffin in 55-70 ℃ hot water is dried at last.
This method utilizes porose plastic flexible pipe or stainless steel tube at fibroreticulate inner released vapour, and heating internally makes the fibers melt bonding, has reduced energy consumption, and it is even to add thermal effect simultaneously, becomes the cloth brute force to be improved, and has improved the productive value of product.
The specific embodiment
In the actual production, select for use diameter at 5-10mm, the heat resistant plastice flexible pipe of wall thickness 0.8-1.5mm or stainless steel tube are as " framework " of nonwoven fabric inside, pipe hollow, two ends link to each other with steam output main pipe with admission respectively, several apertures are arranged on the surface of pipe, hole diameter 1-2.5mm, this framework just temporarily can not stayed in the cloth in nonwoven fabric inside, from nonwoven fabric, spin off smoothly for making at Cheng Buqian, flexible pipe will wrap up with water-soluble paraffin earlier before inserting nonwoven fabric, paraffin such as the water-soluble paraffin of BZW-2 etc., the process of parcel is carried out in the fusion tank of paraffin, with paraffin fusion under 75-93 ℃ temperature, flexible pipe is immersed in that 3-5 takes out second in the paraffin tank, naturally cooling forms and coats, when fleece-laying, the density of the top plastic flexible pipe that has coated with paraffin according to 3-5 root/10cm is arranged between the two layer web, fleece-laying finishes the steam of the end feeding 0.1-0.15MPa of back pipeline, the melted paraffin wax pipeline is extracted out simultaneously, and pressurize with roller rapidly, flush away paraffin in 55-70 ℃ hot water is dried at last.
Preparation method of the present invention is following steps:
With water-soluble paraffin such as the water-soluble paraffin of BZW-2 etc., in fusion tank, melt, under 75-93 ℃ temperature, carry out, can not use steam directly to heat during thawing, heat with electric furnace, programming rate is unsuitable too fast, be raised to 93 ℃ from room temperature in 15 minutes, with diameter 5-10mm, the heat resistant plastice flexible pipe of wall thickness 0.8-1.5mm or stainless steel tube are as " framework " of nonwoven fabric inside, pipe hollow, two ends link to each other with steam output main pipe with admission respectively, arrange several apertures on the surface of pipe, hole diameter 1-2.5mm, and pipe is immersed in 3-5 takes out second in the paraffin tank, naturally cooling form to coat, and the plastic flexible pipe that will be when the fiber lapping coats with paraffin is arranged between the two layer web according to the density of 3-5 root/10cm, and the end that fleece-laying finishes the back pipeline feeds the steam of 0.1-0.15MPa, the melted paraffin wax pipeline is extracted out simultaneously, and rapidly with the roller pressurization, flush away paraffin in 55-70 ℃ hot water is dried at last.
Below in conjunction with embodiment content of the present invention is described further:
Embodiment one
Batching: polyester fiber nonwoven fabric
The preparation method:
With water-soluble paraffin such as the water-soluble paraffin of BZW-2 etc., in fusion tank, melt, under 75-93 ℃ temperature, carry out, can not use steam directly to heat during thawing, heat with electric furnace, programming rate is unsuitable too fast, be raised to 93 ℃ from room temperature in 15 minutes, with diameter 5-10mm, the heat resistant plastice flexible pipe of wall thickness 0.8-1.5mm or stainless steel tube are as " framework " of nonwoven fabric inside, pipe hollow, two ends link to each other with steam output main pipe with admission respectively, arrange several apertures on the surface of pipe, hole diameter 1-2.5mm, and pipe is immersed in 3-5 takes out second in the paraffin tank, naturally cooling form to coat, and the plastic flexible pipe that will be when the fiber lapping coats with paraffin is arranged between the two layer web according to the density of 3-5 root/10cm, and the end that fleece-laying finishes the back pipeline feeds the steam of 0.1-0.15MPa, the melted paraffin wax pipeline is extracted out simultaneously, and rapidly with the roller pressurization, flush away paraffin in 55-70 ℃ hot water is dried at last.
