Description of the invention (1) The present invention relates to a method of opening fibers for composite woven fabrics and their fabrics. The woven fabrics are suitable for processing. The cross-sections are mainly divided and island-shaped, as shown in Figure 4. : (A) ~ (F)], and the polyester component and the polyamide component form a plurality of divided split composite reel and sea island composite suspected dimensions. After processing the suspected dimension using the split-weaving treatment method of the present invention, the knitted fabric can be turned into a soft fabric, and can be dyed in dark tones and improve the fastness of dyeing. The present invention provides a split composite fiber or island-in-the-sea fiber The fabric is made into fabrics, and then the fiber-opening treatment is carried out to obtain an extremely high fiber splitting rate. At the same time, the fibers are divided to make the fabric into a very soft fabric treatment method. General composite ultrafine fiber fiber opening technology, known to have various methods such as NaOH opening, or benzyl alcohol or benzoic acid or solvent opening (trichloroethane), these methods have their own advantages and disadvantages . At present, the processing method tends to save energy, the processing is simple, the pollution problem is few, and the economic efficiency is the primary goal. The acid fiber opening method of the present invention also aims at this. Ultra-fine fibers are not easy to be darkened. In the past, they were dyed after opening the fiber, and then treated by chemical methods, such as fluoropolymer, silicone polymer, acrylic copolymer, etc., to change the reflectance of the fiber surface to achieve darkening. . Generally speaking, these methods have disadvantages such as difficulty in coloring, reduced fiber properties, reduced dyeing fastness, and higher processing cost. The present invention is focused on acidic fiber opening to save energy more than alkaline opening " ...........

After dyeing the fiber and then dyeing the ghost, it can get a dense color, and the dyeing fastness is good, so it can be improved The facts about the disadvantages of alkaline fiber opening or other dyeing methods to thicken the color (please read the precautions before counting and then fill out this page) • Installation • • Line, this paper scale is applicable to the Chinese and Western Standards (CNS) A 4 specifications ( 210x297 public *) A6 B6 202489 V. Description of the invention (2), and research developer. Traditional composite ultrafine fibers are used for salty fiber opening, such as NaOH 10 ~ 30% 〇. W · f and impregnating agent (cation ) At high temperature ~ · 130 ° (: Treat it to reduce the polyester (PET) fiber weight to reach the fiber opening '. The polyester portion is reduced by NaOH and hydrolyzed to produce ethylene glycol to cause a large amount of oligomer (〇1 igomer), which is easy to cause The fiber strength decreases and the fiber turns yellow , Residual cationic surfactants, causing staining in subsequent dyeing projects, poor light fastness, easy-to-slip fabrics and a large number of oligomers and lye wastewater. Another breakthrough method of the present invention is ultra-fine The fiber fabric is dyed first, and then dissolved with an acid treatment agent, so that more excellent dyeing fastness and thickening can be obtained. The present invention is to divide the cross-section with a plurality of divided polyamides Between the polymer and the polyamide-based polymer, an open-fibre split composite reel formed by a polyester-based polymer is woven into a fabric, and then the fabric is subjected to fiber treatment. .. .in 进. © min When all the polyamide polymers are dissolved, the monofilament fineness can be lowered. FV »'·.-... ..........- --..... 15 Zhu is 100 m. Rate. The treatment solution can be dissolved by using organic acid or inorganic acid at room temperature, mainly to dissolve and remove the polyamide part. The processing time is very short, and can improve the split rate. Using this method, the gloss of the fiber And the touch is very good, and it can be dyed in dark shades. The most important thing is that the treated fabric has a washing fastness of more than 4 grades, so the economy is very high. The knitted fabric of the present invention is divided by dissolution The fineness of the monofilament after the fiber is 0.18 Danny (please read the precautions on the back before filling in this page) • Installed _ • Ordered • This paper size is applicable to the Chinese and Western National Standards (CNS) A 4 specifications (210X297 mm) ' —〇— A6 B6 202489 • δ ·, description of the invention (3) (please read the precautions on the back before writing this page), so the fabric can get a very soft touch, especially at 〇.234 ~ 0.02 Denny is the best. Therefore, the setting of the compounding ratio and the number of divisions of the polymer constituting the composite yarn and the monofilament susceptibility of the composite yarn in the present invention is very important. The polyamide used in the present invention is a general synthesis, for example Nylon 6. Nylon 10. Nylon 11. Nylon 12 Nylon 6d Nylon 610. Polyamide copolymers with these as main components; among these polyamides, nylon 6 and nylon 66 are particularly good. Woven fabric made of divided fibers combined with PET and nylon 6 or nylon 66, treated before appropriate refining, etc., and after refining, strong acids of organic or inorganic acids are applied to dissolve and open the fiber at room temperature ' It can improve the splitting rate and shorten the splitting time, so that the ultrafine fiber can be completed. The woven fabric woven from the island orange slice type or split type composite fiber combined with general PET and nylon 6 or nylon 66, after refining and other treatments, must be called Xiaji to kill mildew ^ work, and some Dyeing and finishing factories use high-temperature and high-pressure alkali reduction processing, and the processing time is relatively long, and the cost is relatively increased. Especially how to reduce the cost recently in the textile industry to facilitate the competitiveness of products in the market is very important, so the use of the present invention can reduce costs And improve the quality of W Jibei Central Standard Festival ^ Work Consumers ^ Cooperate with Du Bai ". ^ The present invention utilizes strong acid to dissolve the js weave, which can be dyed faithfully, or after " 4 dyeing and then dissolve to open the fiber treatment. · Also \ —-· | Γ ~ 1 丨 丨 ^^ «II I, | i I | > w 1 | _ Add colorant to the molten polymer, and then perform spinning, false twisting, weaving, weaving and disentanglement; after dyeing, the effect of deep dyeing can be obtained. After the color material is spun, dissolving and removing it will not affect the original color. The standard of this paper is the Chinese and Western National Standards (CNS) A 4 specifications (210x297 g; ¢) 4 Λ 6 Β6 202489 V. Description of the invention (4) (please read the precautions Λ · item to write this page) This invention If the strong acid is used as the dissolving and opening fiber treatment is easier, the acid solution removal concentration is more than 10 Wt%; but if it exceeds 65 wt%, the residual treatment agent after opening is not easy to remove, so the best is 15wt% ~ 50wt% ; Place the braid in an acid-liquid-treating treatment liquid, which is often treated for a short period of time, followed by completely removing and washing the residual chemicals from the braid after the treatment, and finally drying is completed. According to the present invention, it is possible to obtain a substantial PET micro-covering surface that exhibits soft and superior drape, and its silk feel and full touch can obtain a top-grade luster appearance and improve the quality of the product. After weaving or knitting the fiber of the invention into a cloth, $; for the purpose of dissolving the m-plane by acid-donating treatment, the only component left after the fiber is removed by dissolving the fiber As a mother, it can achieve the effect of deep dyeing for dyeing treatment, and the washing fastness can reach 4 to 5 grades. The type of compound suspected dimension treated with acid solution is mainly divided type and island type, and the fineness after dissolving the fiber is between 0.02 and 0.80 Danny, and the component contains only polyester.
