Definitions
- the present invention relates to a continuous process for dyeing and lightening synthetic or celio fibers, and the fibers thus produced. Dyes and / or optical brighteners are applied to the fiber directly during the spinning process in combination with fiber preparation agents.
- the dyeing and optical brightening of filaments and staple fibers is mainly practiced in three ways.
- the optical brightener or the dye is added during polymer production or generally before the fiber is spun.
- the addition before spinning is often carried out using a masterbatch, i. H. a multiple concentrate of the brightener or dye in polyester. 1 - 20% brightener or dye settings are used, which then by
- the brightener or dye can be pre-dissolved in a monomer component and then the polymerization process can be carried out.
- PAN polyacrylonitrile
- the brightener or dye is dissolved together with the polymer in an aprotic polar solvent (e.g. in DMF, DMSO, DMA or DMC).
- an aprotic polar solvent e.g. in DMF, DMSO, DMA or DMC.
- the dissolved mass is spun through nozzles into a hot air chamber, whereby the solvent evaporates.
- the lightening or dyeing of fabrics or knitted fabrics made from filaments or staple fibers is carried out in the so-called block thermosol process or exhaust process.
- the textile fabric is predominantly used with a diluted, brightener or dye-containing dispersion, emulsion or solution, squeezed between rollers and heated to 160 to 220 ° C for 40 - 15 seconds to fix the brightener or dye.
- the optical brightener or dye is applied to the fiber from an aqueous medium at a ratio of about 1: 5 to about 1:40 at 90 to 130 ° C. Filaments and staple fibers can also be lightened directly using the same process.
- DD-104 325 describes a process for lightening polyester which is characterized in that immediately after the shaping process, i.e. Spinning and solidification process, the fiber structure obtained is treated with a dispersion of optical brighteners in water, if appropriate in combination with hydrophilic liquids or preparation agents, and the spinning material is subjected to storage in containers for several hours before being drawn into the fiber raw material.
- the textile lightening processes are costly and time-consuming processes with high water and energy consumption, and corresponding economic and ecological disadvantages. Furthermore, in order to achieve appealing white effects, high amounts of brightener are also used, since the brightener has to penetrate deep into the fiber in order to achieve good fastness properties. Indications for the amounts of brightener used are 100 to 300 ppm in the spinning mass process, while in the textile lightening process between 100 to
- 1500 ppm optical brightener can be used in its active form (i.e. 100%).
- the invention thus relates to a process for the continuous lightening or dyeing of synthetic fibers or Celiosis fibers by one optical brightener or a dye and a fiber preparation agent in contact with the fibers to be lightened or dyed, and then heating these fibers to a temperature of at least 100 ° C.
- Another object of the invention are colored or, in preferred
- Embodiment lightened fibers that can be produced by this method.
- the fibers of the invention carry dyes or optical brighteners only in a limited area near the fiber surface, but not in the fiber core.
- the fibers are therefore not thoroughly interspersed with dye or optical brighteners, but rather they comprise a colored or lightened part on the outside and a non-colored or barely colored or lightened part in the core.
- the latter is also referred to as a weak fluorescence core.
- the low-fluorescence core has a diameter of 10 to 90, particularly preferably 30 to 80, in particular 50 to 75% of the fiber diameter.
- the low-fluorescence core contains at most 30, particularly preferably at most 0.1 to 10% by weight of the total amount of optical brightener on the fiber.
- Preferred synthetic fibers are polyester fibers, polyacrylonitrile fibers (PAN), and
- PA Polyamide fibers
- PU polyurethane fibers
- PU polypropylene fibers
- viscose fibers and mixtures of these fibers with each other.
- Fiber preparation agents are an indispensable aid in the production of synthetic or cellulosic fibers. It is about
- the fiber preparation system is applied to the surface of the fiber using various methods, the most important of which are as follows:
- Neat Oil applications When applied as an aqueous emulsion, this is usually done at ambient temperature. Depending on the viscosity of the preparation used, Neat Oil applications require application temperatures of approx. 50 - 60 ° C. In the further course of the fiber processing process, the preparation on the fiber is partially exposed to significantly higher temperatures. Stretching processes always take place above the glass point, usually approx. 140 - 160 ° C for polyester. Highly drawn filaments often even go to processing temperatures just below the melting point of polyester, i.e. to approx. 250 to 260 ° C. Modern high-temperature heaters in texturing expose the fiber material to temperatures of 550 ° C and above for a short time.
- the properties of the fiber preparation system are predominantly dominated by the first three compound classes a) - c).
- Additives such as Corrosion inhibitors often play a subordinate role, but are indispensable from case to case. The aim is often to control the entire requirement profile using as few components as possible.
- Lubricants are substances that control the tribological properties of the fiber preparation system. The main thing is the friction between the capillaries (so-called thread-thread adhesion or
- Thread closure and the adjustment of the friction on different metallic machine parts (thread-metal friction).
- Other materials are also used in fiber production (especially when texturing POY filaments) such as Polyurethane, ceramic materials and plastic straps (such as so-called “Murata belts”).
- the lubricants were mainly based on paraffinic mineral oils, so-called highly purified "white oils”. Silicone oils are also often used here.
- synthetic esters have recently been increasingly used (predominantly based on natural ones
- organic compounds containing sulfo groups such as e.g. sulfonated oils and
- the acid groups remaining on the sulfur atom are at least partially neutralized with lye (e.g. NaOH).
- emulsifiers are often used to produce homogeneous mixtures of the two classes of substances. This applies both to the application of fiber preparations as an aqueous emulsion and in bulk (so-called "Neat Oil application").
- surfactants and their preparations can be used as emulsifiers. These are e.g.
- Oxalkylation products of fatty acids, fatty acid amides, fatty alcohols, fatty amines or alkylphenols can also be used.
- the number of emulsifiers available is arbitrarily large. When selecting the corresponding substances, however, it must be taken into account that the emulsifier must "match" its lubricating properties, i.e. its effect is not impaired, but may even be supported. The emulsifier must neither influence the fiber material nor contact materials such as Change texturing or friction discs chemically or mechanically (e.g. by swelling). For these and many other reasons, alkoxylation products as enumerated above have largely become established today. It should be noted that the antistatic substances mentioned in group b) can also have emulsifying properties.
- these temperatures are between 100 and 220 ° C., preferably between 130 and 200 ° C., very particularly preferably 190 ° C.
- the fiber material can be exposed for a short time at temperatures of 550 ° C and higher, with exposure times in the 1/10 second range and below.
- Preferred temperatures for polypropylene are 160-280 ° C, for polyamide 130-170 ° C.
- thermosetting of PES brighteners requires fixing times of 15 to 40 seconds at temperatures of 160 to 220 ° C to fix the brightener in the fiber.
- Concentrations of, for example, 35 ppm brightener or dye (with respect to active substance) effects can be achieved which are conventional Process can only be achieved with a multiple of this amount of brightener or dye.
- optical brighteners or dyes for synthetic fibers are suitable as optical brighteners or dyes.
- these products can be provided with dispersants or, in the case of water- or solvent-soluble products, added to the preparation in dissolved form.
- the composition of the dispersing agent is not critical, but it must not cause any precipitations or separations with the preparation system.
- the commercially available dispersion brighteners or water or solvent-soluble types meet these requirements.
- Suitable optical brighteners or dyes for the process according to the invention are nonionic polyester brighteners or dyes, anionic PA or viscose brighteners or dyes or cationic polyacrylonitrile brighteners or dyes.
- Nonionic brighteners or dyes can produce excellent white effects on polyamide or polyolefin fibers.
