Description
Technical field:
The present invention relates to Regenerated Polyester Staple Fiber processing technique fields, and in particular to a kind of to be processed again using waste polyester bottle chip
The pre-treating technology of raw terylene short fiber.
Background technique:
It is the main path of the current polyester recycling and reusing in China using waste polyester bottle chip production regenerated fiber, however this
A little fibers are mainly the cotton of some low sides, filled-type product, since the expansion and homogeneity of production capacity are serious, regenerated fiber enterprise
Industry is in meagre profit state.Therefore high-endization of regenerated fiber, functionality just seem necessary.
And dust and greasy dirt are attached in the waste polyester bottle chip recycled, it is desirable to be processed into Regenerated Polyester Staple Fiber, need first
Waste polyester bottle chip is cleaned.The cleaning way routinely used is washing, and not only water consumption is big, but also cleaning effect has
Limit, can not efficiently remove the dust and greasy dirt for being attached to bottle on piece, and subsequent dry duration, to extend processing week
Phase.
In order to solve this problem, before our company develops a kind of processing regenerated terylene short fiber using waste polyester bottle chip
Treatment process is crushed by two-stage bottle piece being changed into particle form, in order to clean and subsequent drying；It is crushed simultaneously using cold
Freeze processing assistance method, shortens grinding time and ensure that grinding particle size；And it cleans and method is assisted using cleaning agent, guaranteeing clearly
Shorten scavenging period while washing effect and avoids the problem that increasing cleaning wastewater treatment difficulty using conventional cleaning agent is existing.
Summary of the invention:
Technical problem to be solved by the present invention lies in provide one kind to shorten grinding time, guarantee grinding particle size, contracting
Short scavenging period, the utilization waste polyester bottle chip for guaranteeing cleaning effect and not will increase cleaning wastewater treatment difficulty processing regenerated are washed
The pre-treating technology of the short fibre of synthetic fibre.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
Using the pre-treating technology of the processing regenerated terylene short fiber of waste polyester bottle chip, include the following steps:
(1) two-stage crushes: first waste polyester bottle chip is transferred in 5~10 DEG C of freezing chambers, is produced after level-one freezing processing,
And the particle of 5~10mm of granularity is made through pulverizer, then gained particle is transferred in 0~5 DEG C of freezing chamber, through second level freezing processing
After produce, the particle of 0.5~3mm of granularity is made through pulverizer then to get waste and old polyester particle；
(2) it cleans: gained waste and old polyester particle is sent into rotary drum washer, injection cleaning in rotary drum washer
Liquid is cleaned at 300~500rpm of revolving speed, and cleaning solution is discharged after cleaning, then draws off waste and old polyester particle；
(3) it dries: once purged polyester granulate being sent into roller dryer, and at 200~400rpm of revolving speed
Water content is dried to lower than 0.5wt%；
(4) it is micronized: the polyester granulate of drying being transferred in -5~0 DEG C of freezing chamber, is produced after three-level freezing processing,
20~50 μm of granularity of micro mist is made to get waste and old polyester micro mist through micronizer again.
The level-one freezing processing time is 8~12h in the step (1), and the second level freezing processing time is 3~8h.
Drying temperature is 70~80 DEG C in the step (3).
The three-level freezing processing time is 3~8h in the step (4).
Scavenging period is 5~15min in the step (2).
Cleaning solution is dissolved in water by cleaning agent and is made in the step (2).
The cleaning agent is decyl glucoside, and dosage is that every 1kg water dissolves 0.5~5g decyl glucoside.
The cleaning agent is decyl glucoside-pyroglutamic acid carboxylate, and dosage is that every 1kg water dissolves 0.5~5g decyl
Glucoside-pyroglutamic acid carboxylate.
The decyl glucoside-pyroglutamic acid carboxylate is made of decyl glucoside, pyroglutamic acid through esterification,
Preparation method are as follows: first decyl glucoside and pyroglutamic acid are dissolved in the water respectively, are configured to decyl glucoside solution
With pyroglutamic acid solution, then the concentrated sulfuric acid is added dropwise into pyroglutamic acid solution and adjusts solution ph to 3~4, decyl Portugal is then added dropwise
Polyglycoside solution is warming up to reflux state insulation reaction after being added dropwise, after reaction be concentrated under reduced pressure be made solid content 65~
75% lotion, gained lotion are sent into freeze drier after cooled to room temperature, and dry obtained solid is through pulverizing
15~20 μm of granularity of micro mist is made to get decyl glucoside-pyroglutamic acid carboxylate in machine.
The decyl glucoside and the molar ratio of pyroglutamic acid are 1:5.
The cleaning agent is poly glycol monomethyl ether-pyroglutamic acid-poloxamer carboxylate, and dosage is the dissolution of every 1kg water
0.5~5g poly glycol monomethyl ether-pyroglutamic acid-poloxamer carboxylate.
Poly glycol monomethyl ether-pyroglutamic acid-poloxamer the carboxylate by poly glycol monomethyl ether, pyroglutamic acid,
Poloxamer is made through esterification, preparation method are as follows: first respectively by poly glycol monomethyl ether, pyroglutamic acid, poloxamer
407 are dissolved in the water, and are configured to poly glycol monomethyl ether solution, pyroglutamic acid solution and Poloxamer solution, then to burnt paddy ammonia
The concentrated sulfuric acid is added dropwise in acid solution and adjusts solution ph to 3~4, poly glycol monomethyl ether solution then is added dropwise and poloxamer is molten
Liquid is warming up to reflux state insulation reaction after being added dropwise, the cream that solid content 65~75% is made is concentrated under reduced pressure after reaction
Body, gained lotion are sent into freeze drier after cooled to room temperature, and grain is made through micronizer in dry obtained solid
The micro mist of 15~20 μm of degree is to get poly glycol monomethyl ether-pyroglutamic acid-poloxamer carboxylate.
The poly glycol monomethyl ether, pyroglutamic acid, poloxamer molar ratio be 1:3:1.
The beneficial effects of the present invention are:
(1) present invention steps up the brittleness of waste and old polyester material by secondary freezing processing, freezes energy consumption, powder reducing
Broken energy consumption guarantees to shorten grinding time while grinding particle size and reduces the smashing capability requirement to pulverizer, gained polyester
Particle is conducive to subsequent cleaning and drying, so as to shorten scavenging period；
(2) present invention has selected three kinds of different cleaning agents in waste and old polyester particle cleaning, the first cleaning agent is the last of the ten Heavenly stems
Base glucoside belongs to cleaning agent commonly used in the art；Second of cleaning agent is decyl glucoside-pyroglutamic acid carboxylate, by
Decyl glucoside is formed through pyroglutamic acid modification, and cleaning effect is better than decyl glucoside；The third cleaning agent is poly- second two
Alcohol monomethyl ether-pyroglutamic acid-poloxamer carboxylate, cleaning effect are better than decyl glucoside-pyroglutamic acid carboxylate；And
And second of cleaning agent and the third cleaning agent belong to waterborne cleaning agent, the dust and oil of absorption waste and old polyester particle surface attachment
Flocculate is formed after dirt and is deposited in and cleans wastewater produced bottom, can be removed through filtering, not will increase wastewater treatment hardly possible
Degree；
(3) resulting waste and old polyester particle can be directly used for regenerated terylene after pre-treating technology of the present invention processing
The processing of short fibre avoids influencing subsequent machining technology due to dust and greasy dirt cleaning are not thorough；And gained waste and old polyester particle
Belong to micro mist rank, conducive to subsequent blended with unclassified stores or terylene short fiber is made in reacting processing.
