Abstract
The utility model relates to a corn fiber leather substrate. The leather substrate is made of staple fibers which are uniformly distributed and connected in a staggered manner, and needle puncture holes are distributed on the leather substrate and penetrate the upper and the lower surfaces of the leather substrate, so that fiber knots are distributed irregularly and randomly from the surface to the inside of the whole leather substrate. The corn fiber leather substrate has the benefits that (1) the corn staple fibers are adopted as raw materials to endow the leather substrate with the characteristics of high hygroscopicity, antibacterial effect, environment friendliness, elasticity and the like; and (2) the needle-punching non-weaving process is adopted in combination with the random ratio control method and the cross-lapping method, so as to ensure the consistency in warp/weft tensile strength, prevent the problem of high warp tensile strength and low tear strength or low weft tensile strength and high tear strength and increase the overall strength of the leather substrate.
Description
Technical field
The utility model relates to the nonwoven fabric field, especially a kind of zein fiber leather base fabric.
Background technology
In recent years, begin to be subject to people's attention at the textile industry zein fiber, along with the develop rapidly of science and technology, these crops of corn no longer only are to exist as grain.As far back as the eighties, the famous Cargill of cereal company of the U.S. has just succeeded in developing the corn polylactic resin, and on this basis, has succeeded in developing acid fiber by polylactic (PLA fiber), because raw materials for production lactic acid is to make from cornstarch, so also this fiber is called zein fiber.
Zein fiber is a kind of novel ecological, environmental protective fiber type.It is to make lactic acid with cornstarch through biological decomposition fermentation, and the high-purity PLA is made in polymerization under proper condition, again with the PLA for the raw material spinning produces acid fiber by polylactic, raw material is from plant, resource is renewable.Zein fiber is to close first biodegradable fiber in the fibre, and the biochemical decomposability of this fiber is good, can be become carbon dioxide and water by microbial decomposition in soil or in the water, can generate cornstarch again under corn plant photosynthesis., be reproducible fiber so, do not destroy resource and contaminated environment, meet the human kind sustainable development direction, develop zein fiber and textile fabrics thereof energetically and have crucial meaning in the occurring in nature circulation.The zein fiber brute force is higher, and the fiber itself elastic extension reaches 33.38%, is good textile raw material.The zein fiber superior performance, made fabulous drapability, smooth property, sucting wet air permeability, natural bacteriostatic and good heat resistance and the anti-ultraviolet function of being furnished with, and be rich in gloss and elasticity.
In addition on the one hand, along with the continuous expansion of people,, can't satisfy the growing demand of people because of the development of animal's leather is subjected to restricting in many ways to skin class articles for use demands such as leather shoes, leather jacket, Car Cushion, leather trunk bags.But along with the progress of science and technology, people can produce the emulation skin, even produce the new material at the super corium of some aspect of performance.On the market of some developed countries, the price of artificial chamois leather clothes, shoes compete so can to surpass the corium leather price and by the consumer acceptance.The quality of artificial leather depends on the quality of base cloth to a great extent, and therefore the skin class articles for use that make with the Zein fibers base cloth will have the vast market space.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide that a kind of sucting wet air permeability is good, printing opacity is even, flatness is high and warp-wise intensity and latitudinal strength all have raising, especially the zein fiber leather base fabric that is significantly increased of latitudinal strength is used for the zein fiber needle punched non-woven fabrics of leather base fabric.
The technical scheme that its technical problem that solves the utility model adopts.This zein fiber leather base fabric, this base cloth is linked together by staggered the distribution uniformly of staple fibre, is distributed with the pinprick of transfixation upper and lower surface on the base cloth, makes whole base cloth be distributed with the fiber bonding point of irregular random distribution from the surface to inside.
Preferably, described staple fibre is the corn staple fibre, and it is to make lactic acid with cornstarch through the biological decomposition fermentation, the high-purity PLA is made in polymerization under proper condition, again with the PLA for the raw material spinning produces acid fiber by polylactic, raw material is from plant, resource is renewable.In addition it to have a moisture pick-up properties good, characteristics such as natural antibacterial, high-hygroscopicity, natural antibacterial, the feature of environmental protection of having given the zein fiber leather base fabric.To make the zein fiber leather base fabric and have good intensity and planarization in order to make, the specification of the corn staple fibre that is adopted is length degree 35～45mm, the crimped fibre of fiber number 0.5～3D.When the staggered uniform spreading of the FZ fiber of certain-length and fiber number is opened since the curling of staple fibre, make that the frictional force between each staple fibre strengthens, thereby improve the intensity of leather base fabric.
As preferably, the process of zein fiber needle punched non-woven fabrics technology is the first shredding of corn staple fibre, smart shredding, feeding, the belt-type evereven, combing, cross lapping, pre-needling, main acupuncture, several steps such as rolling, wherein the belt-type evereven can guarantee the even of feeding capacity, combing makes fiber open towards the staggered uniform spreading of different directions by controlling mixed and disorderly specific energy, staggered lapping makes and also is covered with the weft fiber layer of being made up of the weft fiber of broadwise arrangement above the warp fiber layers, warp fiber and weft fiber juxtaposition, the pinprick that is uniformly distributed in the fibrage upper surface is through between weft fiber layer upper surface and the warp fiber layers bottom surface; Thereby guarantee the uniformity of made base cloth, improved the bulk strength of base cloth through broadwise intensity.
As preferably, described base cloth thickness is 0.90～1.10mm, and Gram Mass is at 160～320g.
Mechanism is: the employing staple fibre is a raw material, adopt the manufacturing of needle punched non-woven fabrics weaving process, in manufacture process by the mixed and disorderly ratio in the strictness control carding machine with to the mode of staggered lapping staple fibre is launched uniformly in that longitude and latitude is upwards staggered in length and breadth, with the flatness and the bulk strength of raising base cloth.
The effect that the utility model is useful is:
1, adopting the corn staple fibre is raw material, has given this leather base fabric and has had characteristics such as high-hygroscopicity, natural antibacterial, the feature of environmental protection, elasticity.
2, select needle punched non-woven fabrics technology and guaranteed uniformity through broadwise intensity by controlling modes such as mixed and disorderly ratio, cross lapping for use, the warp tensile strength height can not occur, tearing strength is low, the phenomenon that weft tensile strength is low, tearing strength is high takes place.Improved the bulk strength of base cloth.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model;
Description of reference numerals: staple fibre 1, pinprick 2.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done detailed introduction:
