Abstract
The invention discloses a kind of crease-resistant light and thin nylon woven fabric and its processing method.The nylon woven thing is formed by 100% nylon fiber, its grammes per square metre is 35~50 grams/m, and polyester urethane resin and fluorine resin are at least attached with the surface of preceding note nylon fiber, it is more than 2.5 grades to use tamping to measure the wrinkle resistance of the nylon woven thing horizontal positioned after 60 seconds.Gained nylon woven material ground is frivolous, soft, with excellent wrinkle resistance and water repellency.Processing method of the invention is simple and easy to apply, and gained nylon woven thing is especially suitable for outdoor leisure clothes, high-grade ultralight amount down jackets etc..
Description
Technical field
The invention belongs to weave, Material Field, and in particular to a kind of not only wrinkle resistance is superior, and has the light and thin nylon woven fabric of waterproofing function concurrently.
Background technology
It is prevailing with outdoor exercises, small volume, can receive, the easy dress being convenient for carrying or frivolous down jackets etc. are increasingly liked by consumers in general.Such easy dress or frivolous down jackets mostly use the highdensity nylon woven thing of fine denier, but accompanying problem is that, storage fold after easily produce wrinkle, have a strong impact on exterior quality；On the other hand, many cold wets of outdoor exercises environment, nylon fiber easily absorbs moisture causes warmth retention property and snugness of fit reduction.Therefore it is required that nylon woven thing used has crease-resistant and two kinds of functions of water repellent concurrently.
At present, research for the anti-crease finishing of textile is relatively more, as disclosed a kind of textile formaldehyde-free anti-crease finish in patent document CN201510410024, cotton, hair, silk, linen textile are carried out padding processing using the crease-shedding finishing agent of specific composition, significant wrinkle resistant shrinkproof performance is obtained, fabric is presented and is very slided high-elastic state, reduce ironing clothes number of times, and the formaldehydeless release of the finishing agent, safety and environmental protection.But because nylon fiber crystallinity is higher, internal active group is less, and preferable wrinkle resistance can not be obtained using this kind of crease-shedding finishing agent.
And the research processed for the Final finishing of nylon facing material equally also compares many, as disclosed a kind of lightweight flexible wear resistant nylon fabric in patent document CN201410023529, including base cloth layer and at least one of which coating, coating paste urethane modified polyester resin, polyurethane resin, silane coupling agent, crosslinking agent, titanium dioxide and toluene.Nylon facing material anti-wear performance is assigned by coating, while wrinkle resistance and water proofing property make moderate progress, but coating processing is compared to processing is padded, because the peeling of coating resin, washing resistance are difficult to ensure that after expense is quite high, and coating fabric is repeatedly washed.
The content of the invention
It is superior it is an object of the invention to provide a kind of not only wrinkle resistance, and have the light and thin nylon woven fabric and its processing method of waterproofing function concurrently.
Technical solution of the invention is：
Nylon woven thing of the invention is formed by 100% nylon fiber, and its grammes per square metre is 35~50 grams/m（g/m2）, and the surface of preceding note nylon fiber is at least attached with polyester urethane resin and fluorine resin, it is more than 2.5 grades to use tamping to measure the wrinkle resistance of the nylon woven thing horizontal positioned after 60 seconds.
The present invention compensate for the rigid long-chain-segment of the similar polyster fibre of nylon fiber missing by the polyester urethane resin adhered on nylon fiber；The fluoroplast for adhering on nylon fiber simultaneously imparts the good water repellency of fabric again.Processing method of the present invention is simple, is convenient to plant produced.
Specific embodiment
Nylon woven thing of the invention is formed by 100% nylon fiber, and its grammes per square metre is 35~50g/m2.Such nylon woven thing is more frivolous, softness, is particularly suitable for making outdoor leisure clothes and light weight down jackets clothes.Preferred density is 180~235g/m2, it is ensured that fabric it is windproof.
The wrinkle of fabric typically occur in amorphous region, because arranging more loose between macromolecular chain in amorphous region, the hydrogen bond negligible amounts existed between macromolecular or basic structural unit, when deforming upon under external force, part hydrogen bond between macromolecular is broken, and new hydrogen bond can be formed on new position.After external force is removed, due to the inhibition of the new hydrogen bond for being formed, it is set to be immediately returned to original state, or recovery rate is very slow, produces deformation to form wrinkle.I.e. wrinkle are caused by the very slow high resiliency deformation of recovery rate and non-response plastic deformation.In the present invention, polyester urethane resin is attached with the surface of nylon fiber, the resin has elasticity first, can accelerating fibers the gentle elastic recovery of anxious elastic recovery；Furthermore because it contains polyester-type long-chain-segment, the rigidity of fiber can be increased, be effectively improved the wrinkle resistance of nylon fiber woven fabric.It is more than 2.5 grades that thus obtained nylon woven thing uses tamping to measure wrinkle resistance of its horizontal positioned after 60 seconds.
In order to assign woven fabric water repellency, apply a kind of finishing agent with special molecular structure generally by its surface, to change the composition of fiber surface, and by physics, chemically or physically combined with fiber in the way of chemistry, fabric is set no longer to be soaked by water or conventional oils.The surface of the fluorine resin for wherein being used as water repellent finishing agent can be about 10mN/m, with preferable water repellency；And, the characteristics of fluorine resin finishing agent has low concentration, high effect, it is ensured that fabric keeps good feel and excellent breathable moisture permeability after treatment.Compared with organosilicon, hydro carbons finishing agent, in water repellent, refusing the aspect such as oily, antifouling, water-fastness has incomparable advantage.
It is preferred that, it is more than 3.5 grades to use tamping to measure wrinkle resistance of the nylon woven thing horizontal positioned of the invention after 60 minutes.
It is preferred that, according to the method home washings 5 times of JIS L 0,217 103 after, it is more than 2.5 grades to use tamping to measure wrinkle resistance of the nylon woven thing horizontal positioned of the invention after 60 minutes.
The processing method of crease-resistant light and thin nylon woven fabric of the invention is as follows：
The woven fabric of 100% nylon fiber is carried out padding processing using the working fluid at least containing polyester urethane resin and fluorine resin, is then dried, baked, obtain grammes per square metre for 35~50g/m2Product.Wherein, above-mentioned polyester urethane resin consumption is 80~120g/L.When consumption is less than 80 g/L, wrinkle-proof effect is poor.When consumption is higher than 120g/L, high cost, and feel can be influenceed.
Pad processing conditions to be not particularly limited, it is recommended to use two leachings two are rolled, the processing conditions that pick-up is 50~70%.
In view of processing effect, bridging agent is also used in working fluid, bridging agent preferably uses melamine class or isocyanates resinoid.
In the present invention, dry and the time of baking and banking up with earth can be adjusted as needed, preferably drying temperature be 120~150 DEG C, baking temperature be 170~180 DEG C.High temperature is baked again for first low temperature drying, will not make the active ingredient premature reaction of resin, causes hydraulic performance decline.
