Description

Spinning bath
Technical field
The present invention relates to be used for the spinning bath of natural fabric and blending thing, this spinning bath can improve the characteristic of spun yarn, also relates to relevant spinning process.
Particularly, spinning bath of the present invention contain on average have three or more bisulfites (bisulphite) end-blocking-the water-soluble polyisocyanates of N=C=O group.
According to basic sides of the present invention, spinning process comprises and uses this spinning bath to reduce waste fiber, i.e. the amount of discarded fiber in carding process reduces the level of combing and combing process micronic dust, improves process yield.
And the gained spun yarn is very even, has height endurability and elasticity.
Background technology
In that wool fibre or blending thing are transformed in the process of spun yarn, use several chemical addition agents, for example lubricant, antistatic additive, adhesive and wetting agent, emulsifying agent, antiseptic; With their the dissolving or be emulsified in the water, on the paint fiber, in changing the process of spun yarn into, to protect fiber.
The waterborne compositions that comprises above-mentioned chemical addition agent that is used for spinning is called " spinning bath ".
As everyone knows, wool or blend staple change spun yarn into and are undertaken by the method for combing spinning or combing spinning usually; The combing spinning comprises the combing step, and the combing spinning comprises combing step and combing step.
The combing spinning is undertaken by carding machine, and by to fiber, carrying out spinning bath is spray deposited; The combing spinning is a kind of spining technology that is used to handle a large amount of wools and blending thing.
In the combing spinning, the card sliver that obtains by combing directly is sent to spinning process.
On the other hand, in the combing spinning, the fiber of handling with spinning bath is sent to carding machine, becomes card sliver; Careless strip is handled with the spraying spinning bath before entering the spinning stage again, and they are transmitted through combing (combing step) then, arrive the spinning zone then.
The combed yarn spinning needs high machine speed, is more expensive and important spinning process, obtains highest quality spun yarns.
Spinning bath of the present invention both can be used for the combing spinning, also can be used for the combing spinning.
In combing, spinning bath of the present invention also has the following advantages: they can keep machine clean in all processes.
Summary of the invention
The purpose of this invention is to provide the spinning bath that is used for natural animal fiber and blending thing, this spinning bath contain 0.1-6 weight % on average have three or more bisulfite end-blockings-the water-soluble polyisocyanates of N=C=O group.
Another object of the present invention provides the spinning process that is used for natural animal fiber and blending thing, and this method comprises the step on the above-mentioned spinning bath paint fiber of 1-20 weight %.
The specific embodiment
According to basic sides, the method for the application of the invention, the amount of discarded fiber has reduced 15-30 weight % (spinning bath that does not similarly have polyisocyanates with use is compared) at least in the spinning.
On average have three or more bisulfite end-blockings-the water-soluble polyisocyanates of N=C=O group is known, can be according to passing through one or more compounds that contain at least two hydroxyls (polyalcohol) and one or more di-isocyanate reactions described in US 3898197 and the DE 2837851, intermediate product reacts with bisulfite solution and prepares then.
Two (methylol) propionic acid by trimethylolpropane and oxirane, expoxy propane or their mixture and neutralization carries out the polyalcohol of molecular weight between 500-6000, preferred 1000-3000 that condensation reaction obtains and is particularly preferred for preparing water-soluble polyisocyanates of the present invention.
Be preferred for implementing the vulcabond that vulcabond of the present invention can be aliphatic series or alicyclic type, for example general formula OCN-Y-NCO represents, wherein Y is-(CH 2) 6-, 3-methylene-3,5,5-trimethyl-cyclohexane-1-base, 4,4 '-methylene two (cyclohexyl) or 3,3 '-methylene two (cyclohexyl).
The general formula of particularly preferred vulcabond is OCN-Y-NCO, and wherein Y is-(CH 2) 6-, i.e. hexamethylene diisocyanate.
Be used for of the present invention on average have three or more bisulfite end-blockings-the water-soluble polyisocyanates of N=C=O group is commercially available; They are also sold with trade name ElafixPV4 by Lamberti SpA.
Known to the inventor, also nobody proposes to use in spinning bath the polyisocyanates of bisulfite end-blocking to reduce leftover pieces as key component before, improves the spun yarn quality.
The spinning bath that is used for combing preferably contains the polyisocyanates of 1-3 weight %, and the spinning bath that is used for combing preferably contains the polyisocyanates of 0.3-2.5 weight %.
Spinning bath of the present invention also contains one or more lubricants, one or more antistatic additive, one or more adhesives and water except containing above-mentioned polyisocyanates.
The lubricant that can be used for preparing spinning bath of the present invention is the lubricant that is usually used in this area, for example at Handbook of Fiber Finishing Technology (editor SLADE, Philip.NY:Marcel Dekker, Inc, 1998.ISBN description is arranged 0824700481.), fatty acid ester (the ester of stearic acid and oleic acid for example for example, randomly ethoxylation or propoxylation, the propyl diester of myristic acid or cetyl ester, the isopropyl of palmitic acid, octyl group or cetyl ester), mineral oil, fatty alcohol and acid, oxirane, the water solubility copolymer of expoxy propane, or their mixture.
Preferred lubricant mainly is made up of the stearate and/or the oleate of the fatty acid ester, particularly ethoxylation of ethoxylation.
The content of lubricant is 1-20 weight % in the spinning bath, is preferably 5-12 weight %.
Also contain antistatic additive according to spinning bath of the present invention.
Available antistatic additive is the antistatic additive that is usually used in this area, can be anionic, cationic, nonionic or amphoteric; The most frequently used is the antistatic additive of anionic (phosphate of the aliphatic alcohol of for example pure phosphate, aliphatic alcohol phosphate, ethoxylation) and cationic (normally quaternary ammonium salt).
Preferably, the antistatic additive in the spinning bath of the present invention is an anionic; More preferably, mainly form by the mixture of the aliphatic acid of pure phosphate and ethoxylation.
In the combing spinning, the content of antistatic additive is 1-15 weight % in the spinning bath, be preferably 1-10 weight %, and in the combing spinning, the content of antistatic additive is 5-15 weight % in the spinning bath.
Adhesive is other chemical addition agent that contains in the spinning bath of the present invention.
Preferably, the adhesive in the spinning bath of the present invention is the cataloid that disperses.
The content of adhesive in spinning bath is 0.1-2 weight %.
Spinning bath of the present invention also contains other chemical addition agent, for example antiseptic, lubricant, insect-proof agent, provisional dyestuff etc.
The percentage composition of water is 70-90 weight % in the spinning bath.
Spinning bath of the present invention can be used in particular for handling the natural animal fiber, especially wool, goat cashmere, alpaca fibre, mohair, silk and their mixture, and be used to handle the blending thing, be the mixture of natural animal fiber and cotton, polyester, artificial fibre, polyamide or polyacrylic fibre, wherein the amount of natural fabric accounts at least 50 weight % of gross weight.
Fiber is handled with bleaching agent in advance.
Before the combing step, may before the combing step, spinning bath be deposited on the fiber by spraying technology, carried out washing, drying and optional bleaching before the described fiber and handled.
When combing, the amount of the spinning bath on the paint fiber is 5-20 weight %, is preferably 12-18 weight %; When combing, be 1-6 weight %, be preferably 2-4 weight %.
Apply spinning bath of the present invention according to the method for knowing in this area, do not need to carry out special variation.
The yarn count of the spun yarn that obtains by the inventive method is 8-9Ne for combing, is 40-150Ne for combing.
Some advantages of the spun yarn that following examples explanation use spinning process of the present invention obtains.
