Description

Soft weatherability building structure spunlace non-woven new material and its production technology
Technical field
The present invention discloses a kind of softness weatherability building structure spunlace non-woven new material and its production technology, belongs to spinning Knit field of material technology.
Background technology
Construction material is to build one of necessary ingredient, and it can play the effect of protection building, such as waterproof leakproof etc., So that the life-span of building body be protected.Construction substrate mainly has modified asphalt waterproof material, pvc waterproof material, nonwoven Cloth etc..Non-woven cloth products, compared with other type construction materials, have that softness, good waterproof performance, permeability be good, fiber exfoliation is few Deng unique advantage, it is a kind of more satisfactory construction substrate.
But the raising with scientific and technical development and living standards of the people, people are also carrying for the requirement of construction material Height, including for house, building products waterproof, seepage control, each require to strength etc..By carrying out to non-woven fabrics existing on market Research finds, its waterproof, seepage control performance, respectively all need to be improved to strength, the aspect such as fibre shedding situation, feel.
Content of the invention
It is an object of the invention to provide a kind of weatherability building structure of softness with spunlace non-woven new material and its produces work Skill, this soft weatherability building structure spunlace non-woven new material has that good waterproof performance, breathability be strong, no fibre shedding is existing As, the strength in good hand touch, all directions is high and uniform feature.
For reaching above-mentioned purpose, the technical solution adopted in the present invention is:
A kind of softness weatherability building structure spunlace non-woven new material, including being folded in two layers polyester spunlace non-woven Pe microporous breathable film between material.
The present invention softness weatherability building structure production technology of spunlace non-woven new material, using polyester fiber and pe Microporous breathable film is raw material;First polyester fiber is fed successively long curtain, horizontal opener, big storehouse blending box, refined opener, then Carry out being layered combing by carding machine one, carding machine two, the raw material after processing through carding machine one feeds cross lapping machine, drawing-off successively Raw material after drafting machine is processed then is overlapped with the raw material after carding machine two is processed, then is sequentially passed through by machine Spun lacing operation, baking operation, on-line checking operation, coiling process, obtain polyester spunlace non-woven material, finally will be saturating for pe micropore Air film is placed on entrance method hot rolling operation between two layers polyester spunlace non-woven material, obtains finished product.
As the setting further of such scheme, the main cylinder working roll of described carding machine one is 70m/min, main cylinder stripping Roller is taken to be 140m/min, main cylinder rotating speed is 1100 m/min.
The main cylinder working roll of described carding machine two is 60m/min, and main cylinder angle stripper is 120m/min, main cylinder rotating speed For 1150 m/min.
The cross lapping of described cross lapping machine reaches 2 layers.
The total stretch ratio of described drafting machine reaches 3.677.
Described spun lacing operation, its 5 water jet spun lacing pressure are respectively set as: 35bar, 95bar, 105bar, 100bar, 100bar.
Described baking operation, dehydrator temperature control is at 110 DEG C -118 DEG C.
Described method hot rolling operation, hot rolling roll temperature is 100 DEG C, and hot rolling point area is that bond area accounts for always for 8%-30%( The 8%-30% of area).
Described method hot rolling operation, hot rolling roll temperature is 100 DEG C, and hot rolling point area is 25%.Hot rolling point area is preferably 25%, that is, ensure that the intensity of material of the present invention, but also with good feel.
Present invention softness weatherability building structure spunlace non-woven new material is formed by water jet process by polyester fiber Hot rolled technique obtains final products to polyester spunlace non-woven material with pe microporous breathable film again.Because polyester fiber has dry and wet Strongly high, low-cost feature, and pe microporous breathable film fusing point is low, hot rolled after play cementation, increase the strength of material And water resistance.Three-dimensional, the three-dimensional tangled structure made using spun lacing technology, has more skies compared with other technologies Between.And base material is formed by fibre matting, it is not required to add chemical adhesive, therefore, base material has good flexibility and safety Property.Furthermore, the special product structure of spun lacing base material and manufacturing process impart the structure of product sky shape, do not fall fiber.Hot rolling is multiple Close the feel that technique further improves waterproof, seepage control, tensile strength and the softness of product.The present invention uses polyester fiber With pe microporous breathable film as raw material, compensate for the shortcomings of traditional building material all directions strength lack of homogeneity, hair loss, using water Pierce technique and method hot rolling technique substantially increases the handss of present invention softness weatherability building structure spunlace non-woven new material Sense, strength and waterproof, seepage control performance, indices are above traditional building material.
In a word, present invention softness weatherability building structure spunlace non-woven new material, has good waterproof performance, breathability By force, no fibre shedding phenomenon, good hand touch, the strength in all directions be high and uniform feature.
Present invention softness weatherability building structure spunlace non-woven new material, can be widely applied to building, house, waterproof Impervious material field.
