Technical Field

The invention relates to the technical field of fabric dyeing processing, in particular to application of ferment in linen fabric dyeing, a linen fabric one-bath dyeing process and linen fabric.

Background

The linen fabric is a fabric processed by taking linen fibers as raw materials, has the characteristics of quick moisture absorption and dispersion, high breaking strength, small breaking elongation, good waterproofness, soft luster, soft hand feeling and the like, and can be used as special cloth for clothing, decoration, national defense and industry and agriculture. The flax fiber is composed of cellulose and non-cellulose (including pectin, lignin, fatty wax and the like), and when the flax fiber is dyed, most of dye acts on the surface of the flax fiber and cannot sufficiently enter the flax fiber bonded by the non-cellulose such as the pectin and the like, so that the dyeing performance is adversely affected, such as poor dyeing fastness of the dye. In addition, if non-cellulose in the flax fiber is always remained in the fiber, the flax fiber tissue is compact and stiff, so that the softness and comfort degree of the flax fabric are reduced; and pectin and fatty wax residues can cause problems of colored flowers, colored spots and the like.

In order to improve the color fastness of the dye to linen fabrics and improve the dyeing effect and the softness of the linen fabrics, the non-cellulose in the linen fibers needs to be removed. In the traditional process, strong alkali and desizing liquid are added for desizing before the linen fabric is dyed, and non-cellulose is removed by combining a boiling-off process and a strong oxidant bleaching process. But the non-cellulose can be removed by adopting strong alkali desizing and strong oxidant bleaching, but the equipment loss is large and the environmental protection is poor.

At present, the process for performing dyeing pretreatment on linen fabric by using cellulase is available, although compared with the traditional strong alkali and strong oxidant, the environment-friendly property of the cellulase treatment is better; however, the cellulase not only easily damages the strength of the flax fabric tissue, but also easily causes cilia to fall off to influence the beauty of the fabric.

Disclosure of Invention

The invention aims to provide a linen fabric one-bath dyeing process, which can effectively remove non-cellulose in linen fibers and improve the hand feeling, dyeing property and mechanical strength of linen fabrics by loosening the linen fabric with enzyme with biological activity; compared with the traditional strong alkali and strong oxidant, the catalyst is more environment-friendly.

The first purpose of the invention is realized by the following technical scheme:

a linen fabric one-bath dyeing process comprises the following processing steps:

(1) singeing;

(2) and (3) fabric loosening treatment: soaking flax fabric with enzyme for 40-60min to loosen the tissue of the flax fabric; the enzyme comprises fruit enzyme or/and vegetable enzyme;

(3) performing reactive dyeing;

(4) and (6) shaping.

Through adopting above-mentioned technical scheme, ferment with fruit or vegetables, form the ferment that has biological activity, utilize this ferment to carry out loose processing to linen fabric, can hydrolyze pectin and fatty wax, degradation lignin makes linen fabric more soft, and changing waste into valuables has practiced thrift the cost that non-cellulose got rid of, compares in traditional strong alkali and strong oxidizer's desizing and bleaching processing, more green. The method for degumming by using the biological enzyme ensures the rough style of flax fabrics, has strong nostalgic feeling, and is environment-friendly and antibacterial; the color fastness reaches the requirements of superior products, the staining of the six fibers after washing at 40 ℃ reaches the level 4, and the performance is excellent.

Preferably, in the step (2), the enzyme further comprises an antibacterial traditional Chinese medicine enzyme.

By adopting the technical scheme, as the enzyme with biological activity is adopted, in order to further improve the antibacterial performance of the fabric, if the conventional nano silver, nano zinc and the like are adopted, the harm to the biological activity is large, and the silver oxide material can coat the microorganisms to prevent the microorganisms from moving and rapidly die. According to the invention, the fabric is treated by the antibacterial traditional Chinese medicine enzyme, so that the microorganisms of the fruit enzyme and the vegetable enzyme are hardly damaged, and after the fabric is used, the microorganism group is found to be increased, the antibacterial group is increased, and the antibacterial property of the fabric is improved.

Preferably, the step (2) specifically comprises the following operations: adding ferment in an amount of 10-15g/L, soaking flax fabric in the ferment with the above concentration at 53-57 deg.C for 40-60min, and cooling to 38-43 deg.C.

Preferably, the cooling rate in the cooling process is 1.2-1.6 ℃/min.

By adopting the technical scheme, the pretreatment and the reactive dyeing of the enzyme on the linen fabric are carried out in one cylinder, and compared with a one-bath method which is carried out in two baths or even more baths, the one-bath method saves water and energy; the dyeing processing of the shell fabric in one vat is 60min faster than the traditional time, and the clear water is saved by about 12000L in 2 vats.

Preferably, in the step (1), after singeing, adding 10g/L of liquid caustic soda and 1-3g/L of refining agent, heating to 90-95 ℃, and treating for 30-50 min; the mass concentration of the liquid caustic soda is 40%.

By adopting the technical scheme, the flax fabric is deoiled, emulsified and refined.

Preferably, in the step (3), the dyeing time of the active dyeing is 50-60min, and the dyeing temperature is 60-80 ℃.

By adopting the technical scheme, the treatment temperature of the traditional alkali cooking process is about 98 ℃, and the reactive dyeing of the invention reduces the dyeing temperature and saves the energy consumption.

Preferably, the step (4) specifically comprises the following operations: keeping the speed at 45m/min and the setting temperature at 155-165 ℃, and treating the linen fabric by using a 20-40g/L film and a 20-40g/L hydrophilic softening agent to finally obtain the finished linen fabric.

By adopting the technical scheme, the dyed linen fabric is subjected to hydrophilic, antistatic, soft, rebound and other treatments, so that the hand feeling of the linen fabric is improved.

The second purpose of the invention is to provide a linen fabric processed by any one of the linen fabric one-bath dyeing processes.

The third objective of the present invention is to provide an application of the ferment in dyeing linen fabric, wherein the ferment is used in the one-bath dyeing process of linen fabric described in any of the above processes to dye linen fabric, so that the linen fabric is loose and soft.

By adopting the technical scheme, the enzyme is applied to the dyeing process of the linen fabric, the non-cellulose in linen tissue can be removed, the linen fabric is softer and fluffy, the hand feeling and the dyeing fastness of the linen fabric are improved, and the method is green and environment-friendly.

Preferably, the enzyme comprises one or more of fruit enzyme, vegetable enzyme and antibacterial traditional Chinese medicine enzyme.

In conclusion, the invention has the following beneficial effects:

(1) the flax fabric is degummed and loosened by using the enzyme with biological activity, so that the style of rough cloth cover is ensured, the nostalgic feeling is strong, and the environment-friendly antibacterial effect is realized; the effect of removing the colloid is good, so that the color fastness of the fabric is good, and the requirements of superior products are met;

(2) compared with strong alkali or strong oxidant desizing, the treated fabric has the advantages of being plump in hand feeling, natural and full in color, meeting the requirements of environmental protection and being good in color fastness;

(3) fruits, vegetables and antibacterial traditional Chinese medicinal materials are fermented and then applied to dyeing of linen fabrics, so that a new application of the enzyme is developed successfully, and the enzyme is green and environment-friendly;

(4) by adding the antibacterial traditional Chinese medicine enzyme, the antibacterial rate of the treated fabric is up to 99.8%, the antibacterial rate of the fabric after being washed for 10 times is still kept above 84%, and the antibacterial agent is superior to the antibacterial property of the fabric treated by the traditional process and has excellent antibacterial performance.
