Man-made cellulosic fibers are produced by using a naturally occurring source of cellulose (for example, wood pulp), dissolving it in a stretchable solution, and drawing the fiber from the solution. Ly〇cdl fiber is a man-made cellulose fiber made by extruding a solution of cellulose through a spinneret into a coagulation bath (so-called bath stretching method). The method is described in U.S. Patent No. 4,246,221, which uses a tertiary amine group oxide (more specifically, N-methyloxazinone N-oxide, referred to as the hall) as a solvent. (10) The chaotic fiber is different from other artificial cellulose fibers. The artificial cellulose fiber is laid by dissolving the cellulose into the water-soluble chemical towel, and weaving the scent of the scent to dissolve the squeezing The pressed material regenerates the cellulose fiber. The slime fiber includes some types of high strength, which are produced by forming a water-soluble derivative in this way. [Prior Art] The cross-linking treatment of the cellulose fiber cloth has long been It is well known that silk is such that it has the characteristics of wrinkle-free, sputum-free, wash-resistant, etc. The general description of this type of treatment is described in Kirk-Altman Chemicals, published by Willy Technology Publishing. In the third edition of the encyclopedia, the second volume (Jiannian), an article entitled "Spinning" The article on the surface treatment of fiber products, the 79th page of the article, and the "Coloring Encyclopedia," Volume 17 (1987), pages 7-22. The cross-linking agent is sometimes called, he The name of '% § brother, cross-linking resin, chemical surface treatment agent, and resin surface treatment 1292451, agent, etc. Cross-linking agent is a small molecule, which contains a plurality of can react with the hydroxyl group in cellulose to form • Father a functional group. One of the crosslinkers contains an N-methylol resin, that is, it is a small molecule containing two or more N-hydroxymethyl or N-alkoxy groups, especially N _Methoxy. N-hydroxymethyl resin is usually used in combination with an acid catalyst selected to enhance cross-linking performance. In a representative method, - contains a large weight ratio of about 5 to 9% of N The methyl resin cross-linking agent and the acid catalyst solution having a weight ratio of about 0.4 to 3.5% are padded onto a dry cellulose cloth so that it has a weight ratio of 6 〇 to brain /.

The fabric is dried and heated to pass through the fabric of the father's joint. It can be used to dye the fiber, which is usually used for dyeing 1292451. The degree of dyeing achieved in this method is still reduced compared to cotton fabrics that are not cross-linked. Such a characteristic = also has a domain, the job is to use the cross-linked Wei Xue agent as the age-old flower _, so that when the fabric is dyed after the lamp is dyed, the printed and unprinted parts have a master dyeing effect. Another kind of _Slim 4 Mei __Che Quanguo patent Yang 5, and S6 are described. In this method, the cross-linking operation reduces the tendency of the fins to rise. A soft linear polymer (for example, polyethylene glycol) which is used in conjunction with the cross-linking WK to enhance the dye affinity of the cross-linked L_1 fluorene fiber in a post-staining operation. Other methods of dyeing containing cellulose fabrics are described in U.S. Patent No. 4,298,584. Further, the present invention relates to a cross-linking method using the type described, and the object thereof is to overcome the problem of low dyeing degree of the cotton fiber _ Shangxiaxia people riding (t_, Ly (10) u fiber __ dimension). SUMMARY OF THE INVENTION The present invention provides a method for producing a fabric which is uniformly dyed by containing both cotton fibers and man-made cellulose fibers. In this method, a fabric made of fiber-made fibers is produced. And dyeing; characterized in that before the manufacture of the cloth, the man-made cellulose fiber is impregnated with a water-soluble, soft wire and a crosslinking agent reacting with cellulose, and Before the dyeing of the fabric, in the stage of the processing towel, the artificial cellulose is subjected to the cross-linking of the cross-linking agent, thereby reducing the dyeing generality of the rayon fiber to be closer to the affinity of the cotton fiber dye. The standard. ^292451 This method makes the collection of scales _ color, (four) section direct (four), tearing 鸠, purchase, the dye affinity of her saki fiber is a relative value, when - 嶝 scale heavy strain by - test of.

The _ affinity _ test specified for the fiber affinity reading of the method of the present invention is described after the book cap. The uniformity of the dyeing operation in which a clear vivid color can be obtained is usually judged by the naked eye. The dyes used in the secrets of the required secrets. On the other hand, for example, __ ray dyes are more likely to mask the phenomenon of grazing. Keeping these characteristics in mind, we found that, usually, if the man-made cellulose fiber-hetero-affinity is broken, the fiber-green affinity (the fresh value is less than fifteen percent of the negative/negative knife (usually Above, the monochromatic dyeing operation can use the uniformity of the dyeing of the method of the invention. The dye affinity of cotton fibers will vary depending on the category, origin and surface treatment, but usually, if cotton fiber is used The benchmark value is set at 100%, then the standard mucus fiber dye is I* raw, picking 130/. 'The standard Lycell fiber has a dye affinity of about $(10)%. Despite the artificial cellulose Lin and Gu Wei The secret affinity is initially different, but a uniformly dyed blended fabric can be obtained using the method of the present invention. ^292451 Futa, _Weicheng is Ly°ee11 fiber' However, using the method of the present invention, ...', field fiber plum (Cai said, New_) is also fine. Use cross-linking chemical ageing artificial _ _ _ can be edited _ form continued its spinning shape is best before the fiber is stretched into spinning, Even better, two of these fibers The light linear polymer and the crosslinking agent are applied to the artificial cellulose fiber in the form of a solution, which is light (in the form of a miscellaneous, but before being dried for the first time). - Generally, it can be used as a cross-linking agent for the anti-wrinkle treatment of the linum, but it is best to use a cross-cap or a low-age cross-linking agent, preferably. It is used in combination with a catalyst. When the method of the present invention is used to process a cloth, it is preferable to use a zero-formaldehyde cross-linking agent. One type of low-formaldehyde cross-linking agent contains a methylol resin. Suitable N-hydroxyl Examples of the base grease are those described in the aforementioned article by S. K. and Baskets. Examples of such resins include 1,3 - dimethanol-based sub-urea (DMeEU), w-two. Auxiliary propyl urea (DMePU) and 4,5-di-based 1,3-diethanol-based sub-urea (DHDMeEU), other examples include aldose, triazabenzene and carbamate An example of a suitable compound, another suitable crosslinking agent is melamine. As for the zero formaldehyde crosslinker, the preferred class is In the case of 1,3 -dialkyl- 4,5-dihydroxy(alkoxy)hypo-urea, for example, ' 1,3 -dimercapto-4,5-di-diethylidene (DMDHEU). The zero formaldehyde crosslinking agent is butane tetracarboxylic acid (BTCA), and the crosslinking agent used for the anti-wrinkle treatment of cellulose is usually used together with a catalyst (usually an acid catalyst) used in the crosslinking reaction. When 1292451 is recommended to use the method _ method selection _ cross-linking _, it is best to cooperate with the sample-like media. For example, 'N old methyl resin and 1? 3_ two-base one-two wire (burning oxygen) The base of the second acetonitrile is preferably 疋酉a using an acid catalyst, for example, an organic acid, such as acetic acid, or a latent acid (for example, an ammonium salt, an amine salt, a metal salt, for example, Wei Zinc or Tong Magnesium). A mixed catalyst can also be used. Preferably, the water & glutenous, soft, linear polymer is a fully aliphatic polymer, preferably unbranched. It may contain a distal functional group, such as a silk or an amine group, and, if possible, these components also participate in the crosslinking reaction. The green linear polymerization_side reduces the high affinity affinity of the rayon (4) by crosslinking the resin, so that the affinity of the money becomes closer to the cotton fiber-dye affinity. It seems that the effect is achieved by preventing the excessive bribery during the cross-linking reaction, opening the __ to the extent of the degree, and allowing enough dye to enter the desired level of dyeing. . After dyeing, the soft linear polymer does not function at all and is washed away by age so that it is no longer retained by any of its functional groups in the cross-linking reaction. A preferred class of such soft linear polymers includes polymeric glycols, such as polypropylene glycol (PPG), and especially polyethylene glycol (PEG) which is also a hybrid of ethylene glycol-doped amines. It should be known that 'this _ soft linear polymer through f is a mixture of molecules with various bond lengths'. The biliary sign is based on their average molecular weight and chain of ships, their chain length can be about 5 to 15 〇 _子. The example of the hexagram is a polyethylene glycol (pEG) with an average molecular weight between 200 and 2000. The crosslinker, soft linear polymer and all catalysts are preferably The solution (preferably an aqueous solution) is applied to the man-made cellulose fiber. The polymerized ethylene glycol (for example, polyethylene glycol and polypropylene glycol) is usually water-soluble. The solution can be applied to the fiber by a known method, for example. Said, 1292451 The / liquid can be used to & rolling Shunwei, preferably from the dry Langlin bundle, or the fiber bundle can pass through the treatment bath of the solution. In addition, the staple fiber can also be treated. After applying the solution, it is not hj: the fiber that stays The moisture content of the bundle is about 45% by weight in the weight ratio, usually in 働. /Processing / mixing can be combined with a weight ratio of 1 to 05 to 15% (preferably a crosslinking agent (to 1 (8)% of the living reference table 7F) Preferably, the miscellaneous liquid contains a weight ratio of G1 to 5% _ _ Wei Wei. When using a catalyst, the solution may contain from four (by weight) to 5% by weight (preferably G · black ~ 2 · (five) touch The medium may be combined with one or more other substances, for example, a soft treatment agent for the fiber. The treated person Qianweiweiwei preferably contains a weight of _ G. 2% to 5% ( More preferably, it is 1/. to 4%) of a crosslinking agent (calculated on the basis of the weight of cellulose), and a weight ratio of (four) to 3% of a soft linear polymer (based on the weight of cellulose). The cloth made of impregnated artificial fiber and cotton fiber may be knitted, plain woven or non-woven fabric. In the needle _, _ _ _ _ _, the fiber is first spun into a spun yarn. A preferred method is _ Included in the artificial _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ It can be used, the common blending ratio is the weight ratio of the dead (Q), the cotton 'and the 5G: 5G blending _ is the most common. The field step (or the cultivation step) is carried out before the dyeing. Any other treatment is required prior to dyeing, then the crosslinking step should be carried out prior to the other mash treatment to avoid loss of the cross-linking chemical from the treated spun during the _-type processing step. And the % step is to read the fabric or the spinning. When the cloth is knitted fabric or non-woven fabric 1292451, the father's joint step is preferably the pudding. But, when the fabric to be treated is plain weave fabric, The joining step is preferably carried out on the spinning, and the bamboo is the same. If the spinning is not cross-linked, the loading of the cloth before the money will cause the yarn to be lost. Crosslinking at the fiber stage is also a way of °, 彳 & ^ not secretive, as crosslinked fibers may become flying and difficult to process during the spinning and weaving stages. The rut of the rut includes the use of a soft linear polymer and a crosslinking agent to impregnate the rayon.

The earlier drying treatment, for example, after the application of the crosslinking chemical, the drying of the climbing beam should be carried out under some conditions (mainly lower temperature), and the crosslinking reaction does not occur under such temperature conditions. occur. For example, during the drying process, the temperature of the fiber itself (rather than the air temperature) is preferably maintained below 110 °C. Alternatively, the fibers are preferably not dried to a moisture content of less than about seven percent by weight of the fibers. The dyeing of the fabric can be carried out using dyes and methods conventionally used to dye cellulose cloth. Suitable dyes include direct dyes, anthraquinone dyes, sulfuric acid dyes, and reactive dyes. So use commercially available dyeing machines, including hydraulically driven jet dyeing machines, for example, Thies Ecosoft, Gaston County Futura, and HisakaCircular CUT-SL, as well as air jet dyeing machines, for example 12 1292451 'N-methyloxazole An aqueous solution of a heterocyclically fired N-oxide (NMMO) in an aqueous solvent is passed through a spinneret into an aqueous coagulation bath to form a fiber in the form of a fiber bundle, which is then washed. Stretch out the Lyocell fiber. The washed, newly stretched fiber bundle is generally referred to as "from un-dried, through a water-based padding bath at a temperature of 55 C. The aqueous bath contains 30 g/L DMDHEU zero formaldehyde ^ resin The concentration of PEG specified after the text (average molecular weight of 400), and the side of 4 g / liter of gas 'as a cross-linking surface. The impregnated shredded beam and then passed through the oven, temperature 1GG ° C, 2 minutes between the B temple , dried to a water level of 7% from the weight of the fiber. Example 1, the specified concentration of PEG in the pad bath is 5 g / liter, for Example 2 ' } It is 1 gram gram per liter. For the fiber of the example ,, the pEG level on the fiber is 0.5% by weight of the fiber; the fiber of the embodiment 2 is ι·〇% by weight of the fiber. The fiber dye affinity of Example 1 and Example 2 was measured and the prepared samples were tested by the specified method. For this purpose, each length of each of the dried, impregnated fiber bundles was cut by β. Mm short staples, spun into 20 Tex spinning. These spun yarns are made of plain needles and crepe fabrics' And by heating the fabric at nc for 1 minute, the resin and the polymer are _ on the mother-block fabric. In fact, the cross-linking should be performed with shorter scales, but for a longer period of time Make sure that the cross-cuts are 5 grams each of the cross-linked fabrics using the fingerprint method for dye affinity, and then separately with the cotton fiber and the complete Lyocell fiber sample. Sasaki is shown in the following table: 15 1292451 Table Sample Dye Affinity (%) Cotton 100 Standard Lyocell 141 Standard Mucilage Fiber 131 Lyocell Fiber 102 of Example 1 Lyocell Fiber 114 of Example 2 These are in accordance with Example 1 and Examples The dried and impregnated fiber bundles produced by the two were tested for their dyeing uniformity after being blended with cotton fibers. Similarly, '% Cong's staple fiber was cut from each fiber bundle, and, in each-example In these, the staple fiber and the combed cotton fiber (four): % are blended. The blend of the side fibers is spun into a 30s Ne spinning, and the individual spinning is then knitted into a unit weight of 2 square meters per square meter. 〇公克's double-sided Joe Sai Luo Structure. The cross-linking of the resin on each of the fabrics is carried out by squashing the squad 7 (the temperature of the rc is heated for 1 minute y.), as a comparison object for the sample 'from cotton fibers and The blend of Lyocell staple fibers was spun with the same count as a fabric of the same count to make a fabric of the same structure which was not treated with the crosslinker and PEG.
