Description
Technical field
The present invention relates to functional spunlace non-woven cloth preparation fields, and in particular to a kind of cashmere protein cellulose fiber spun lacing
The production method of non-woven fabrics.
Background technique
Wool is the important source material of textile industry, it has many advantages, such as, and elasticity is good, hygroscopicity is strong, warmth retention property is good, and wool is spun
Fabric is famous with its luxurious graceful, natural style comfortable and easy to wear, especially the cashmere good name that has " soft gold ", but due to
Price is high, for the production of non-woven cloth, using few, using the non-woven cloth of good woool production, is only limitted to needle thorn manufacture
Few some advanced industrial cloth such as woollen blanket, advanced Nomex, undercoat, the coarse wool being generally adopted by wool processing, lead to
Cross the products such as the pad cloth of the methods of needle thorn, loop bonding production carpet, the sandwich of layers of needle punched carpet, insulation heat insulating material, this kind of sheep
The length of hair is different, contains miscellaneous height, and spinnability is poor, and processing is more difficult, and product can pass through chemical processing, to improve quality.
In order to increase the utilization of cashmere, modern industry combines cashmere with viscose rayon, under certain condition will be certain
The protein hydrolysate stoste and cellulose (viscose glue) stoste of concentration carry out spinning, and post-treated processing by certain proportion mixing
Ideal regenerated protein is made, in the peptide bond (- CO-NH -) among such protein fibre and cellulose-OH shape
At hydrogen bond, stronger molecular binding affinities are generated, to form the composite fibre of novel protein, but substantially hydrogen bond is still fallen within
Molecular separating force, not enough in conjunction with dynamics, by repeatedly washing, protein falls off, and related performance decline is obvious, and for power
For learning performance, such composite fibre is still less than viscose rayon.
Summary of the invention
It is an object of the present invention to provide a kind of production methods of cashmere protein cellulose fiber spunlace non-woven cloth, provide good
It is thick to solve cashmere (wool) the complex fiber material surface that the prior art is produced containing cashmere (wool) complex fiber material
The problem of rough, easy pilling.
To solve the above problems, technical solution provided by the invention are as follows:
A kind of cashmere protein cellulose fiber spunlace non-woven cloth, is made of: 5-15%'s the fiber of following weight percent
The cotton fiber or synthetic fibers of cashmere protein cellulose fiber, 85-95%, cashmere albumen are grafted on fiber by silane coupling agent
On element, the fiber number of fiber is 1.33-1.67dtex.
A kind of production method of cashmere protein cellulose fiber spunlace non-woven cloth, includes the following steps:
(1) prepare cashmere protein cellulose fiber: prepare mass fraction be 5-15%, the cashmere albumen that pH value is 11-12
Cashmere albumen alkaline aqueous solution is heated to 55-65 DEG C, silane coupling agent is added dropwise under agitation by alkaline aqueous solution, is added dropwise
System temperature is risen to 100-110 DEG C after complete, cashmere albumen pretreatment fluid is obtained after maintaining reaction 2-3 hours, then drops to
The cashmere albumen pretreatment fluid of preparation is added according to the ratio of cashmere albumen pretreatment fluid and viscose glue volume ratio 1:10 after room temperature
In viscose glue, bucket among maturation is entered after being sufficiently mixed, is always maintained at stirring among maturation in bucket, maintains reaction 6-10 hours
Spinning is directly carried out afterwards obtains wet cashmere protein cellulose fiber；
(2) the wet cashmere protein cellulose fiber for obtaining step (1) carries out mixing combing with cotton fiber or synthetic fibers
Obtain wet non-woven fabrics fiber net；
(3) it carries out 360 degree of full dimension spun lacings to the wet non-woven fabrics fiber net that step (2) obtains with clear water to consolidate, totally 11
Spun lacing process, spun lacing pressure are stepped up at spiral gradient；Last in spun lacing process punches skill by high-pressure water-jet together
Art forms non-woven fabrics cloth cover every square centimeter while being evenly distributed 60 deflector holes when shaping；
(4) spunlace non-woven cloth made from step (3) is moved into tunnel drier, is in 80~100 DEG C, transmission speed
Under conditions of 0.1~0.5r/min, 2~3h, the aqueous humidity 7.5%-9.5% of final non-woven fabrics are handled.
Further, in step (1), the dosage of silane coupling agent is the 30-40% of cashmere albumen quality, and it is even that silane is added dropwise
The time for joining agent is 20-30min.
Still further, the silane coupling agent is γ-(2,3- the third oxygen of epoxy) propyl trimethoxy silicane or γ-shrink
Glycerol ether oxygen propyl trimethoxy silicane.
The invention has the following advantages over the prior art:
(1) present invention is combined with the preparation process of cashmere protein cellulose fiber, and the cashmere albumen in non-woven fabrics contains
Amount is up to 5-15%, and to be covalently keyed, cashmere albumen becomes one of cotton fiber (viscose rayon) for cashmere albumen and cotton fiber
Point, since cashmere albumen and cotton fiber are to be covalently keyed, the original mechanical property of cotton fiber is not influenced, is keeping cellulose fiber
It ties up and assigns feel and correlation properties smooth, soft as its cashmere, such cashmere protein fiber on the basis of excellent textile performance
(wool) complex fiber material of cashmere made from cellulose fiber surface is smooth, is not easy pilling；
(2) cashmere albumen and cotton fiber are grafted on cellulose with covalent bond, are existed without free cashmere, are usually used
Cheng Zhong, cashmere albumen is without departing from will not come to harm to the people of cashmere allergy；
(3) clear water is used when spun lacing, has not only played spun lacing consolidation, but also swim adhering to above cashmere protein cellulose fiber
From cashmere rinse out, be not necessarily to washing operation after the completion of spun lacing, only operated with first drying, energy consumption, water consume are low.
(4) it is organically combined by the grafting of cashmere albumen, front end spinning technique and spun lacing process, obtained fiber is without drying
It is dry to be directly entered spun lacing step, and without exclusively carrying out spun lacing pretreatment, integration production substantially reduces process flow,
Technique is simplified, method is easy, is easy to large-scale production.
