Abstract
The invention relates to an ultrathin full-viscose dipping non-woven fabric preparation method. The preparation method comprises the following steps of: (1) primary cotton web processing: sequentially carrying out cotton laying, opening, quantitative cotton feeding, pre-carding, longitudinal and lateral cotton web laying and main carding on a raw material-viscose to form a primary cotton web; (2) primary rolling: longitudinally and laterally rolling the primary cotton web for primarily forming; (3) dipping and secondary rolling: dipping in a polyvinyl alcohol adhesive for dipping and forming; (4) drying: drying the formed cotton web to form a piece of non-woven fabric; and (5) coiling: coiling and packaging. The preparation method adopts the quantitative cotton feeding and two-time rolling, so that the ultrathin characteristic of the prepared non-woven fabric is ensured, the thickness of the non-woven fabric is not more than 0.05mm, the weight of the non-woven fabric is only (9+/-1.0)g/m<2>, and the non-woven fabric can be widely used for interlining materials of clothing such as shirts, western-style clothes and fashionable dresses.
Description
Technical field
The present invention relates to a kind of preparation method of full viscose glue immersion non-woven fabrics, relate in particular to the preparation method of the full viscose glue immersion non-woven fabrics of a kind of ultrathin type.
Background technology
Full non-woven viscose fabric raw material is a viscose, and viscose is a kind of chemical fibre, but is different from the crude oil derived chemical fibre that comes out such as terylene, but extraction string, polymerization forms the fiber based on cellulose, so very approaching with cotton on the performance, and comfort level also is better than cotton.The wadding that is widely used in various clothes, have comfortable, ventilative, characteristics such as softness.
The preparation method of general nonwoven fabric is careless for impurity elimination, the fiber combing, and air lay, the rolling moulding is rolled in the dip bonding agent, these basic technologies of heating, drying and baling.Generally between 0.1-1mm, thickness is difficult to be controlled at below the 0.05mm nonwoven thickness of producing by above technological process.For addressing this problem, the present application the preparation method of the full viscose glue immersion non-woven fabrics of a kind of ultrathin type, adopt and technology such as pound quantitatively for cotton and secondary to roll, the nonwoven thickness≤0.05mm of preparation, weight only is (9 ± 1.0) g/m
2, can be applicable to the wadding of wadding, the especially summer clothes of various clothes.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and technical problem to be solved by this invention provides the preparation method of the full viscose glue immersion non-woven fabrics of a kind of ultrathin type.
To achieve these goals, the present invention takes following technical scheme to realize:
The preparation method of the full viscose glue immersion non-woven fabrics of a kind of ultrathin type comprises the following steps:
(1) be processed into elementary web: the raw material viscose successively through shop cotton, shredding, quantitatively to cotton, pre-comb, spread web in length and breadth, main combing forms elementary web;
(2) once pound and roll: pound in length and breadth and roll elementary web, make one-step forming just;
(3) dipping, secondary are pounded and are rolled: the dipping poly (vinyl alcohol) binder, pad moulding;
(4) drying: pound and roll into type web drying and be shaped into nonwoven fabric;
(5) rolling: the dried nonwoven fabric of clot, packing.
In a preferred embodiment of the present invention, further comprising described is between the 10.7-12.1kg to cotton weight quantitatively.
In a preferred embodiment of the present invention, further comprise described secondary and pound that to roll required polyvinyl alcohol water solution concentration be 3-12%.
In a preferred embodiment of the present invention, further comprise described drying process and be and secondary is pounded the type web of rolling into to put into temperature be 130-145 ℃ roasting dry machine oven dry 2-4 hour, make (9 ± 1.0) g/m
2Ultra-thin immersion non-woven fabrics.
In a preferred embodiment of the present invention, the product two ends need neatly when further comprising described packing, and tighten at two, plastic sheeting is adopted in external packing, thickness 〉=0.06mm, and interior paper tube specification is: interior paper tube thickness is 4mm, the built-in pipe internal diameter is 40mm, and width of cloth length is 860mm or 960mm.
The beneficial effect that the present invention reached:
The invention solves the defective that exists in the background technology, adopt among the preparation method of the present invention quantitatively to pound to cotton and secondary and roll, can prepare the ultra-thin full viscose glue immersion non-woven fabrics of thickness≤0.05mm, weight only is (9 ± 1.0) g/m
2, can be applicable to the wadding of wadding, the especially summer clothes of various clothes, have refrigerant, ventilative, softness, tension, characteristics such as comfortable.
