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 and back dressing liquid of wear-resisting, folding nonwoven material in particular.
Background technology
Raising and industrial continuous upgrading along with people's living standard, application wear-resisting, the 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 have determined the service life of product to a great extent.
Existing wear-resistant nonwoven material is normally behind product in the arrangement process, and what add natural rubber, emulsion polymerized styrene butadiene rubber, butadiene rubber, butadiene-styrene rubber uses component design with, adds some auxiliary agents then to improve the performance of product in glue.
Thus, now the abrasion resistance of the high abrasion nonwoven material that uses on the market generally also has only 20,000-30,000 times, has run into the raising bottleneck, makes and has been subjected to very big restriction in service life of final products.
In view of this, the inventor is wear-resisting at nonwoven material in the prior art, the further investigation of the deficiency on the folding quality, has this case to produce then.
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 can't continue to break through on the wear-resisting and folding number of nonwoven material to solve prior art.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of manufacture method of wear-resisting, folding nonwoven material, wherein, earlier by terylene short fiber through shredding, mixed, combing, lapping, pinprick reinforcement, be calendared into non-woven base fabric, again with this base cloth through after dressing liquid pad, HEAT SETTING makes; Dressing liquid is composed as follows after this:
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 back dressing liquid is first after carboxy styrene-butadiene rubber Ruzhong adding crosslinking agent vulcanizing treatment, adds starch, carbon black and water again, through evenly making after the stirring.
Further, the back arrangement is 140-180 ℃ with the temperature of HEAT SETTING, 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 back dressing liquid, wherein, constituted by following component:
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 back dressing liquid is first after carboxy styrene-butadiene rubber Ruzhong adding crosslinking agent vulcanizing treatment, adds starch, carbon black and water again, through evenly making after the stirring.
After adopting said structure, the present invention relates to a kind of manufacture method and back dressing liquid of wear-resisting, folding nonwoven material, wherein carboxylic styrene butadiene latex is to add a small amount of carboxylic acid and other auxiliary agent with butadiene, styrene, copolymer by the emulsion polymerisation generation, because the introducing of hydroxyl, increase the polarity of latex, improved adhesive property; Reasonably combined by carboxylic styrene butadiene latex and carbon black again can improve the ABRASION RESISTANCE of non-weaving cloth greatly; Certainly excessive carbon black then can make non-weaving cloth become fragile, and influences the folding quality of product; Starch then has certain strengthening action, adds resilience and feel that amount of starch can improve product, but excessive starch can influence the ABRASION RESISTANCE of product; The crosslinking agent Main Ingredients and Appearance is sulphur, can make the mutual bonding cross-linking of a plurality of linear molecules reticulate structure at the intermolecular generation bridging action of line style, and reasonably combined by with carboxylic styrene butadiene latex can improve the folding quality of product.
Core of the present invention is by using a kind of special back dressing liquids of reasonably combined formation such as carboxylic styrene-butadiene rubber, carbon black, starch, can produce a kind of wear-resisting, folding non-weaving cloth then, carry out wear-resisting test with Martindale's method and find that cloth cover does not still have broken hole or obviously damage after wearing and tearing 60000 times; Carry out anti-white performance test at bending machine, angle of flexure is 90 °, subduing frequency is 60 times/per minute, subdue and find sample still non-cracking phenomenon or obvious folding line after 8 hours, the present invention has high-wearing feature and folding resistance, can improve the service life of product greatly, make conveyer belt not need frequent replacing.
