Abstract
The invention discloses a manufacturing method for a wear-resistant, folding-resistant non-woven material, and an after-treatment liquid. The manufacturing method comprises the following steps: allowing polyester staple fibers to be subjected to opening, kneading, combing, lapping, needling reinforcement and calendaring so as to obtain the non-woven base cloth; and then allowing the base cloth to be subjected to padding and thermal shaping via the after-treatment liquid. The after-treatment liquid comprises the following constituents: 100-200 parts of carboxylic butadiene-styrene latex, 1-5 parts of starch, 3-8 parts of cross-linking agent, 10-20 parts of carbon black, and 1-100 parts of water. According to the invention, the carboxylic butadiene-styrene latex, the carbon black, the starch and other constituents are reasonably matched to prepare the tailor-made after-treatment liquid. The non-woven cloth made of the non-woven material has no holes or obvious damages on surface after being worn 60 thousands of times during a Martindale wear-resistant test, and has no fracture phenomenon or obvious creases on the samples after being subjected to 8-hour flexing on a flexing tester in a white resistance test. Due to the adoption of the manufacturing method, with high wear-resistant and folding-resistant properties, the service life of the product is greatly prolonged, and the conveying belt is not required to be changed frequently.
Description
Technical field
The present invention relates to a kind of nonwoven material and manufacture method thereof, relate to a kind of manufacture method of wear-resisting, folding nonwoven material in particular.
Background technology
Along with raising and the industrial continuous upgrading of people's living standard, application that is wear-resisting, folding reinforcing material is very extensive now, as conveyer belt, high-grade material for sole of shoe, racket handle scytoblastema cloth etc., wherein material wear ability, folding resistance determine the service life of product to a great extent.
Existing wear-resistant nonwoven material normally in product Final finishing process, add natural rubber, emulsion polymerized styrene butadiene rubber, butadiene rubber, butadiene-styrene rubber mixed come component design, in glue, then add some auxiliary agents to improve the performance of product.
Thus, the abrasion resistance of the existing high abrasion nonwoven material commercially used, generally also only has 20,000-3 ten thousand times, encounters raising bottleneck, the service life of final products is limited by very large.
In view of this, the present inventor is wear-resisting for nonwoven material in prior art, deficiency further investigation on folding quality, then has this case to produce.
Summary of the invention
Main purpose of the present invention is to provide a kind of manufacture method of wear-resisting, folding nonwoven material, is improving the problem that the wear-resisting and folding number of nonwoven material cannot continue break through to solve prior art.
In order to reach above-mentioned purpose, solution of the present invention is:
A manufacture method for wear-resisting, folding nonwoven material, wherein, first by terylene short fiber through shredding, mixed, combing, lapping, pinprick reinforcement, be calendared into non-woven base fabric, then this base cloth is rolled through Final finishing immersion, HEAT SETTING obtains; This Final finishing liquid composed as follows:
Carboxylic styrene butadiene latex: 100-200 part;
Crosslinking agent: 3-8 part;
Starch: 1-5 part;
Carbon black: 10-20 part;
Water: 1-100 part.
Further, this Final finishing liquid is first after carboxy styrene-butadiene rubber Ruzhong adds crosslinking agent vulcanizing treatment, then adds starch, carbon black and water, obtained after uniform stirring.
Further, the temperature of Final finishing and HEAT SETTING is 140-180 DEG C, and heat-setting time is 10min.
Further, the fiber number of this terylene short fiber is 1.4-3.0D, and length is 38-51mm.
Further, this is wear-resisting, the thickness of folding nonwoven material is 0.6-3.0mm, and grammes per square metre is 200-600g/m
2.
Further, this is wear-resisting, the gel content of folding nonwoven material is at 300%-350%.
Another object of the present invention is to provide a kind of Final finishing liquid, wherein, be made up of following component:
