Abstract
The invention discloses an environment-friendly dyeing and finishing technology of a cotton cellulose fabric. The technology comprises the following steps: pretreatment; preshaping; modification treatment; dyeing; mordant removing; soaping; color fixing; post-treatment; drying; shaping; calendaring; rolling. According to the technology, pretreatment is carried out through the adoption of helicase and alpha-amylase, and acetic acid aqueous solution of chitosan, hydrogen peroxide and epoxy chloropropane is adopted, so that the property of the cotton cellulose fabric is fundamentally modified, and the dye-uptake of the fabric is increased; during the dyeing procedure, large quantities of alkaline substances and inorganic salt are not used, and a levelling agent and a dispersing agent are added, so that the dye uniformity is improved; natural dye is used, so that environmental pollution is avoided, and the demand of environmental protection is met; modification treatment and fire retardant treatment are carried out on the fabric through the adoption of montmorillonite, so that the fire resistance of the fabric is high; self-cleaning treatment is added in post-treatment, so that the self-cleaning capacity, wrinkle resistance and water washable firmness of the fabric are improved; the whole technology is environment-friendly and free of pollution.
Description
Technical field
The present invention relates to a kind of environment-friendly type dyeing and finishing technology of cotton fabric.
Background technology
Fiber is divided into chemical fibre and natural fabric, chemical fibre has fast light, wear-resisting, easily wash easily dry, do not go rotten, the advantage such as not damaged by worms, be widely used in and manufacture clothing fabric, filter cloth, conveyer belt, rotary hose, rope, fishing net, electric insulated, medical treatment suture, tyre cord and parachute etc., natural fabric refer to nature exist and growth, there is the fiber that weaving is worth, chemical fibre is raw material with the macromolecular compound of natural polymer or Prof. Du Yucang, through preparing spinning solution, the fiber of what the operation such as spinning and post processing obtained have textile performance.
Cotton fiber is a kind of natural fabric, moisture absorption and good permeability, soft and warming, is therefore widely used in field of textiles.Traditional dyeing all adopts chemical dye to dye usually, but the pollution of chemical dye to environment is larger, in order to reduce environmental pollution, begin one's study at present and adopt natural dye to dye, and usually dye at a lower temperature when adopting natural dye to dye, also just lower to the requirement of equipment like this, energy consumption also can reduce.
But the Color of natural dye is poor, its fixing degree of the fabric dyed is lower, usually in dyeing course, a large amount of soda ash and inorganic salts are added in order to improve fixing degree, this brings larger difficulty to the treatment of dyeing wastewater of high salinity, can ecological environment be destroyed as directly discharged, causing the salinization of soil.Use natural dye usually also can use some mordants containing metal ion simultaneously; although the use of mordant can improve Color; if but mordant can not be removed completely in post processing; not only can bring pollution to environment; the coloured light of fabric also can be made simultaneously mostly to become dim, affect vividness and the aesthetic property of DYED FABRICS.In addition, in order to reduce the dyeing difficulty of follow-up dyeing, usually need before dyeing to carry out preliminary treatment to fabric, but current preliminary treatment is all adopt the alkaline solution such as sodium hydrosulfite, sodium carbonate to carry out High Temperature Pre process substantially, larger to the damage of fiber.Simultaneously; usually can notice in current fabric post-treatment operation that flexibility arranges; but otherwise arrangement is ignored; the automatically cleaning ability of such as fabric; if fabric has automatically cleaning ability; so its clean aspect after polluting again can be easier, can avoid adopting strong dirt-removing agent carry out decontamination or long-time immersion and make the life-span of fabric impaired.
Summary of the invention
Goal of the invention: the problems referred to above existed for prior art, the object of this invention is to provide a kind of environment-friendly type dyeing and finishing technology of cotton fabric.
Technical scheme: for achieving the above object, the technical solution used in the present invention is as follows:
An environment-friendly type dyeing and finishing technology for cotton fabric, comprises the following steps:
(1) pre-treatment: pre-treatment is carried out to cotton fabric, be specially: use urea 1-1.5g/L, non-phosphorus degreasing agent 4.5-5.5 g/L, scouring agent 1-1.5 g/L, 30% hydrogen peroxide 8-10 g/L, glusulase 8-10 g/L, α-amylase 8-10 g/L, carry out ultrasonic process 1-2 min; bath raio is 30:1; ultrasonic frequency is 45Hz, refills clear water and washs 2 times, then dry after process terminates in the ultrasound bath of 40 DEG C; Scouring agent is the ZJ-CH58 low-temperature refining agent that Guangzhou Zhuan Jie Chemical Co., Ltd. produces.
(2) pre-setting: pre-setting process is carried out to cotton fabric, add heat resistanceheat resistant flavescence agent 8-10 g/L during sizing, setting temperature is 150-160 DEG C, and the speed of a motor vehicle is 20-30m/min, overfeeding 5-10%; The heat resistanceheat resistant xanthochromia agent FK-161 that Beijing Chemical Co., Ltd. in Textile produces;
(3) modification: the cotton fabric after sizing is put into plasma apparatus and carries out Cement Composite Treated by Plasma, discharge power is 100W, and discharge frequency is 13.56MHz, processing time 3min; And then put into water-bath and process, containing shitosan 3-5 g/L, hydrogen peroxide 4-6 g/L in water-bath, acetic acid 20-30 g/L, epoxychloropropane 4-6 g/L, bath raio is 40:1, modification 60-80min at 40 DEG C, refills clear water and washs 2 times, then dry after process terminates;
(4) dye: cotton fabric is carried out dyeing process, be specially: under room temperature, fabric is immersed in the clear water of dyeing machine, then in water-bath, bleeding agent 1.5-2.5g/L is added, diffusant DN 0.8-1.2g/L, levelling agent 1.5-2.5 g/L, natural dye 1.5-2.5%(owf), mordant ferrous sulfate 3-5 %(owf), imvite 3-5 g/L, bath raio 20:1, and by pH buffer Acetic acid-sodium acetate, the pH value of dye liquor is adjusted to 5.5-6, cyclically charging material 20min, then dyeing machine heats up, programming rate is 1 DEG C/min, when temperature rises to 70 DEG C, insulation dyeing 20min, dyeing machine continues to heat up, programming rate is 0.5 DEG C/min, when being warming up to 80 DEG C, insulation dyeing 20min, dyeing machine continues to heat up, programming rate is 1 DEG C/min, when being warming up to 90 DEG C, insulation dyeing 40min, then dyeing machine cooling, cooling rate is 2 DEG C/min, when temperature is down to 40 DEG C, dyestuff is discharged also injected clear water again, 15min is rinsed with clear water, the cotton that levelling agent adopts Beijing Chemical Co., Ltd. in Textile to produce levelling agent FK-482,
