The invention discloses a single-side dyeing method of woven fabrics, which belongs to the new technical field of textile printing and dyeing. A method for single-side dyeing of woven fabrics, firstly pre-treating woven fabrics such as pure cotton, tencel, and elastic fabrics, including gray cloth turning over, singeing, desizing, scouring, bleaching, mercerizing, etc.; secondly, full-width single-side dyeing, One-side dyeing of woven fabrics is to apply the color paste glue A to the woven fabric through a coating machine, and then go through high-temperature hot air tentering, oxidation, soaping, water washing, drying, and falling cloth; then apply the color paste glue B Coloring on woven fabrics, high temperature hot air tentering, and falling cloth through a coating machine. This technology realizes the fashion of denim clothing, casual clothing and children's clothing, and has obvious ecological functions; it also solves the problem that the fabric can be dyed on one side with sulfur dyes and paints on the coating and setting machine. Technical problems; at the same time, it saves water, steam, and electricity compared with the conventional processes of vat and reactive dyes, and reduces a large amount of dyeing sewage discharge. The side of the single-side dyed fabric that is in contact with the human skin does not contain any dyes, chemicals, and additives. It is ecological and environmentally friendly. It is an ideal fabric for denim, casual wear and children's wear.

The invention discloses a dyeing treatment process for pure cotton fabrics based on pure natural biological preparations, which is designed for solving the technical problems that the environment is seriously harmed in an existing pure cotton fabric dyeing treatment process, and the human health is harmed in an application process. The adopted technical scheme is as follows: the dyeing treatment process comprises the steps of singeing, desizing, boiling-out, bleaching, dyeing, softening treatment and preshrinking treatment, and the key point is that biological preparations, which are respectively a desizing enzyme solution, a boiling-out enzyme solution, glucose oxidase solution and a plant dye, are respectively adopted in the steps of desizing, boiling-out, bleaching and dyeing. The dyeing treatment process has the technical effects that the operation is simple; the pure natural biological preparations almost do not contain any toxic substance, and wastewater produced in the treatment process is less and biodegradable, so that under the premise of keeping the characteristics such as softness, sweat absorption, comfortableness and naturalness and the like of pure cotton fabrics, the harm to the environment is alleviated, and the harm to human body is avoided, and therefore, the process has a zero-pollution environmental friendliness characteristic.

The invention provides a method for dyeing natural fiber fabric with vegetable dye. According to the dyeing method, the natural vegetable dye prepared from fructus gardenia is adopted to dye the natural fiber fabric into blue, and after the fructus gardenia is subjected to smashing and screening, vegetable oil and pectin removal, purification and concentration, feeding to a macroporous resin column, addition of cellulase and other steps, the natural vegetable dye is obtained; the natural fiber fabric is subjected to pretreatment for removal of surface impurities, sodium periodate is added for oxidation, rare earth or a rare earth derivative is added, the prepared vegetable dye is added, the natural fiber fabric is dyed into blue, lastly the dyed fabric is washed, soaped, rinsed, dewatered, dried and shaped, and the blue cotton fiber fabric is obtained. According to the dyeing method, the natural vegetable dye prepared from fructus gardenia is adopted to dye the natural fiber fabric into blue, the dyeing effect is good, the whole process is easy to control precisely, large-scale production can be carried out, and the dyed natural fiber fabric has a natural antibacterial effect.

The invention discloses a bamboo plate filament sound absorption decorative board material and a manufacturing method thereof. The bamboo plate filament sound absorption decorative board material comprises a board material body, and a thin vertical gluing single board, a transverse gluing single board, a first fire-proof sound absorption board, a fine filament board and a second fire-proof sound absorption board which are successively arranged from top to bottom are in glue splicing to form the board material body; the processing steps are successively divided into material preparation, levelling, brownness treatment, surface blasting, drying, dehumidification, gluing, vertical gluing single board preparation, transverse gluing single board preparation, fine filament board preparation, splicing together, hole punching, sanding, japanning, edge sawing or cutting, inspecting, grading and repairing and packaging. According to the manufactured bamboo plate filament sound absorption decorative board material, the problem that market timbers are in a shortage state is solved, the requirements of regeneration or circular economy and green environmental protection are met, the additional value of bamboo materials, bamboo branch materials of the bamboo materials, small-sized bamboo materials, bamboo material processing surplus materials and the like is improved, the method is beneficialfor ecological environmental protection, and better economic benefits, social benefits and ecological benefits are achieved.

The invention provides a method for dyeing cotton fiber fabric through natural plant dye .According to the method, the natural plant dye prepared from gardenia fruit is adopted for dyeing the cotton fiber fabric into blue, the gardenia fruit is subjected to the steps of crushing, screening, plant oil and pectin removing, purification, concentration, macroporous resin column applying, cellulase adding and the like, and then the natural plant dye is obtained; the cotton fiber fabric is subjected to pretreatment so that surface impurities can be removed, then a setting machine is used for soaking the cotton fiber fabric twice and rolling the cotton fiber fabric twice, then sodium bicarbonate is used for treatment, rare earth or a rare earth derivative is added, then the obtained plant dye is added, the cotton fiber fabric is dyed into blue, and finally water washing, soaping, rinsing, dehydrating, drying and setting are carried out to obtain the blue cotton fiber fabric .According to the dyeing method, the natural plant dye prepared from the gardenia fruit is adopted for dyeing the cotton fiber fabric into blue, the dyeing effect is good, precise control over the whole process is easy, large-scale production can be carried out, and the cotton fiber fabric obtained through dyeing has a natural antibacterial effect.
