Definitions
- the invention relates to the field of textile technology application, and more particularly to a degumming process of jute.
- the jute fiber obtained by this process can be applied to the production of apparel fabrics. Background technique
- hemp textile and apparel fabrics are favored by people is mainly because hemp fiber has good moisture absorption, gas permeability, low static electricity and good anti-infective ability.
- the aforementioned hemp textile and apparel fabrics mainly refer to linen, ramie raw materials or garment fabrics which are blended/interwoven with other fibers such as wool, chemical fiber, silk, polyester, spandex, etc., which are made of these materials.
- the degumming process is: unpacking, hemp, pickling, simmering, simmering, simmering, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing, smashing
- One drying Applicants have tried to degumming jute with this process. As a result, the pigment removal rate of jute is only 50%, and the appearance of the fiber is brownish yellow. The jute fiber with this sense color is blended with cotton or with glue. Or the fabric obtained by blending with other fibers can not only obtain the ideal whiteness of the fabric through the bleaching process, but also hinders the dyeing of the light color, and the color is gray.
- the removal rate of the pigment must be as high as 80% for the fabric material.
- lignin impurities in jute are the main cause of skin itching, and the removal rate is generally required to reach 70%. Otherwise, even if the degumming effect is remarkable, it is not suitable for the production of apparel fabrics.
- jute has its inherent fiber bundles that are rough, hard, difficult to remove pigments, and poorly spinnable and pungent. These are the taboos of apparel fabrics, which have caused jute to be used for processing sacks for a long time. In addition to materials, a small amount is also used to make carpets, rough wallpapers and other crafts such as satchels, mats, etc. In recent years, the large-scale application of packaging materials such as chemical fiber and plastic products has caused the market of jute to shrink, resulting in a large backlog of soil selectivity, short growth period, high yield of jute, and low price. On the contrary, due to the high soil selectivity and low yield of flax, the price of flax continues to rise. Make linen textiles untouchable to ordinary consumers.
- Chinese Patent Licensing Publication No. CN1047415C discloses a process and equipment for jute or kenaf chemically modified spun cotton blended yarn, and the chemical modification process steps are as follows:
- the modified jute or kenaf fiber is blended with cotton fiber.
- the shortcomings of this patented technical solution are as follows: 1.
- the pectin content is not less than 0.5% and the lignin content is less than 2% as described in the effect section of the specification, because the color of the product obtained from it is shallow. Brown can be judged;
- the Chinese Patent Licensing Bulletin No. CN1139684C introduces a method for producing an improved style of hemp fabric, the method uses ammonia or nitrogen treatment, soft treatment, depilation treatment, anti-shrinkage treatment, but the method is mainly for hemp fabrics. In terms of products, jute is excluded, and no specific degumming or decontamination of any kind of raw hemp is involved.
- the softness (flexibility) and spinnability of fibers are inversely proportional to the amount of lignin contained in the fibers.
- the pectin lignin content is less than 0.5% and 2%, respectively, and is spinnable.
- the maximum activity of the mixed enzyme recommended by it is not fully exerted, mainly because the pH value is not reasonably changed according to the requirements of different enzymes, resulting in The removal rate of pectin and lignin is low; the second is that the mixed enzyme is used at a bath ratio of 1:30, so the bath ratio greatly reduces the labor productivity of the flax degumming process, resulting in the treatment of water and other resources.
- the comparative literature fails to reveal the enlightenment of the reasonable determination of the pH value of the mixed enzyme;
- the experimental object of the literature is flax, because the lignin content in flax is twice as low as that of jute (please see Gu Mingjin, etc.)
- An object of the present invention is to provide a degumming process which can effectively remove impurities such as pigments and lignin in jute fibers, and which is simple in handling and low in handling cost.
- the object of the present invention is achieved by a jute degumming process which comprises the following steps -
- the raw hemp taken out is sent to the hemp, and then washed, oiled, dehydrated and dried in order to obtain the jute fiber after decolorization and impurity removal.
- the complex enzyme treatment comprises a two-step treatment: firstly treating the original hemp at pH 5-5.5, 55 ° C - 60 ° C. (Under this condition, the activity of laccase to remove lignin impurities can be fully exerted), and then treated at pH 7.5-8, 60 ° C-7 (TC) (the pectinase can be removed under this condition) The activity of the glue and the impurities (ie, discoloration) which adhere to the pectin are fully exerted).
- the aqueous solution of the complex enzyme is an aqueous solution prepared by mixing a compound of pectinase and laccase having a weight of 1% to 2% by weight of the original hemp and 15 times the weight of the original hemp. .
- the weight ratio of pectinase to laccase in the complex enzyme described in the step (2) is 3:1.
- the aging stacking time described in step (2) is 10-14 hours.
- the hot water used for the hot water cleaning of the raw hemp described in the step (2) is from 85 ° C to 95 ° C.
- the reducing bleach and bleach remover described in step (3) are from 1% to 2% by weight of the original hemp.
- the reductive bleaching of step (3) is carried out at 85 °C to 90 °C.
- the oiling in the step (4) means that the amino silicone oil and the polyethylene emulsion are prepared in a ratio of 1:1 and then 1% by weight of the original hemp and 10 times the weight of the original hemp. Soak the original hemp fiber, soak for 30 minutes and the temperature is 45'C.
- the decolorization rate of the jute fiber and the removal rate of the lignin impurity are 89% and 76%, respectively, and the appearance color of the obtained jute fiber is white, and the obtained jute fiber is combined with other fibers such as cotton and chemical fiber. Blending or interlacing can fully meet the requirements of apparel fabrics, and the process steps are simple, water and other resources are saved, the cost is low, and the processing efficiency is high. detailed description
- the compound enzyme prepared by pectinase and laccase in a ratio of 3:1 (weight ratio) is taken as 1% by weight of the original hemp and mixed with 15 times the weight of the original hemp, and then put into the treatment tank.
- the medium adjust the pH to 5-5.5 with acetic acid and baking soda, raise the temperature to 55 ⁇ , and put the raw sesame into the treatment tank for 50 minutes. Under the temperature and pH conditions, the laccase activity can be fully utilized.
- pectinase Good to remove impurities such as lignin, then adjust the pH to 7.5-8 with acetic acid, then raise the temperature to 60 ° C, continue to treat for 50 minutes, at this temperature and pH conditions, the activity of pectinase can be obtained Give full play to facilitate the good removal of pectin and impurities that adhere to pectin. After taking out, stack it for 14 hours to continue to use the enzyme and then wash it with 85 ⁇ -90 ⁇ hot water.
- the pectinase and laccase are respectively used, such as Pectinase (Bioprep) and Lactolide (Denilite) manufactured by Novozymes, Denmark.
