Abstract
The invention discloses an industrial polypropylene fiber regenerated cotton blended yarn with flame retardance. The industrial polypropylene fiber regenerated cotton blended yarn is characterized in that the industrial polypropylene fiber regenerated cotton blended yarn is prepared by the following raw material by weight: 40-43 parts of waste and old cotton fabrics, 15-17 parts of cotton yarn scrap, 3-4 parts of modified starch, 1-2 parts of diphenyl phosphate ester, 2-3 parts of nano-sized magnesium hydroxide, 1-2 parts of fatty amine polyoxyethylene ether, 39-44 parts of polypropylene, 3-5 parts of nano-sized zinc oxide, 12-14 parts of liquid paraffin, 9-10 parts of nano-sized titanium dioxide, 1.5-2 parts of carboxymethyl cellulose, 1-1.5 parts of ethoxylated lauramide and a proper amount of water. industrial polypropylene fiber regenerated cotton blended yarn has an advantage of scientific and reasonable formula. The industrial polypropylene fiber regenerated cotton blended yarn is prepared through a specific process. The prepared product is manufactured to a regenerated fiber by means of the waste and old cotton fabrics, thereby reducing production cost, saving energy and reducing emission. Not only is product quality reduction prevented, but also the quality of the regenerated cotton yarn is improved through blending with the modified polypropylene short-fiber blended yarn. The industrial polypropylene fiber regenerated cotton blended yarn can be widely used for manufacturing an industrial fabric, a carpet, etc.
Description
Technical field
The present invention relates to textile technology field, particularly a kind of industrial polypropylene fibre regeneration cotton blended yarn with flame retardant effect and preparation method thereof.
Background technology
Along with population in the world increases severely, countries in the world all will control the utilization of ploughing, and the plantation of the mulberry tree of cotton, fiber crops, sericulture all will be restricted, and traditional cotton textile raw material is subject to multiple restriction.The material quantities such as related data shows, the leftover pieces of domestic regeneration cotton yarn use in 2010 can reach about 3,000,000 tons altogether.By 50% be that cotton recuperated yarn is estimated, by every mu of output of cotton 200 kilograms calculating, be equivalent to the output in about more than 700 ten thousand mu of cotton fields.Recuperated yarn had both achieved the recycle of resource, had saved limited resource, solved again a leftover pieces process difficult problem, for environmental improvement contributes.But because raw material is after shredding, fibre length shortens, powerful decline, light resistance is poor, easily go mouldy, which limits the utilization regenerating cotton yarn.
Polypropylene fibre is the synthetic fiber that the isotactic polypropylene obtained with propylene polymerization spins for raw material, is called polypropylene fibre at the commodity of China.Polypropylene fibre light weight, intensity are high, good springiness, wear-resisting, corrosion-resistant, there is electrical insulating property and warmth retention property, regain is low, simultaneously cheap, chemically-resistant character is good, have in drapery field and use widely, but due to polypropylene fibre heat-resisting, resistance to ag(e)ing is poor, limits its application in fields such as clothes.
Summary of the invention
The object of this invention is to provide a kind of industrial polypropylene fibre regeneration cotton blended yarn with flame retardant effect and preparation method thereof.
The present invention is first by smashing waste and old cotton goods, waste cotton leftover bits and pieces fiber, then special process slurry starching is put into, this slurry contains the composition such as nano-sized magnesium hydroxide, diphenylphosphate, synergy can improve the anti-flammability of regeneration cotton fiber, can improve the intensity of fiber, elasticity and sun protection simultaneously; Second step dissolves atoleine by flooding with hot ethanol first time after polypropylene and the melt spinning such as atoleine, nano zine oxide, the polypropylene fibre of porous surface can be formed, flood again with nano titanium oxide dispersion again, nano titanium oxide is evenly dispersed in polypropylene fibre surface, further raising anti-ultraviolet property, reduces the shortcoming of material; Finally by two kinds of fiber blend resultant yarns, strength ratio Quality Pure Cotton Yarn Production becomes large accordingly, has certain flame retardant effect simultaneously, improves the quality of regeneration cotton yarn, may be used for the products such as manufacture filtrate, carpet, industrial fabric.
In order to realize object of the present invention, the present invention is by following scheme implementation:
An industrial polypropylene fibre regeneration cotton blended yarn with flame retardant effect, is made up of the raw material of following weight portion: waste and old cotton goods 40-43, cotton yarn leftover pieces 15-17, converted starch 3-4, diphenylphosphate 1-2, nano-sized magnesium hydroxide 2-3, aliphatic amine polyoxyethylene ether 1-2, polypropylene 39-44, nano zine oxide 3-5, atoleine 12-14, nano titanium oxide 9-10, carboxymethyl cellulose 1.5-2, ethyoxyl bay cruel amine 1-1.5, water are appropriate;
A kind of industrial polypropylene fibre regeneration cotton blended yarn with flame retardant effect of the present invention, be made up of following concrete steps:
(1) ball milling 30 minutes is placed in ball mill after being mixed with aliphatic amine polyoxyethylene ether by nano-sized magnesium hydroxide stand-by, converted starch is put into stirred tank, add the water of 20 times amount, be heated to 80 DEG C, then add the nano titanium oxide of ball milling product, diphenylphosphate and half amount, stir 30-40 minute formation processing slurry with the speed of 120-150 rev/min;
(2) by waste and old cotton goods, cotton yarn leftover pieces mixing after use machine smash to fibre length be 2-3 millimeter, the blended fiber smashed is immersed 40-50 minute in process slurry, then dry at 80-90 DEG C of temperature, then the fiber after drying is made regenerative mixed fiber sliver through comb and parallel cotton fibers prior to spinning, combing;
(3) polypropylene is heated to complete melting, then mix with atoleine, nano zine oxide, obtain polypropylene staple fibre by melt-spinning technology after stirring, be then immersed in the ethanol being heated to 45 DEG C and take out after 30-40 minute, dry at 90-100 DEG C;
(4) carboxymethyl cellulose is added in the water of 30 times amount, be heated to 40-50 DEG C, be stirred to after forming clear solution and add all the other residual componentss, double-steeping slurry is made in abundant dispersion, then the polypropylene staple fibre after step (3) being processed continues to be immersed in double-steeping slurry, finally dries and obtains modification polypropylene staple fibre;
(5) the modification polypropylene staple fibre that regenerative mixed fiber sliver step (2) obtained and step (4) obtain carries out drafting, namely coarse sand, spinning process obtain the present invention.
The invention has the beneficial effects as follows: scientific formulation of the present invention is reasonable, by the blended yarn that special process is made, compensate for the shortcoming of cotton fiber and the sun protection difference of polypropylene fibre, heat-resisting quantity difference, the product made adopts waste and old cotton goods to make regenerated fiber, reduces production cost, energy-saving and emission-reduction simultaneously, not only product quality can not be reduced, also by the polypropene staple blended yarn blending with modification, improve the quality of regeneration cotton yarn, process industry fabric, carpet etc. can be widely used in.
