In this embodiment of the present application, the cool feeling lining fabric may also include other cool feeling fiber materials, and any lining that can realize cool feeling may be used in this application.
In a second aspect, the present application provides a processing method of the ice silk cool fabric according to the first aspect, as shown in fig. 1, the method includes the following steps:
s1, obtaining a cloth blank containing cotton fibers, bamboo pulp viscose fibers and graphene modified nylon fibers;
specifically, yarn 1 may be cotton fiber yarn, and yarn 2 may be bamboo pulp viscose fiber yarn; or the yarn 1 can be bamboo pulp viscose fiber yarn, and the yarn 2 can be cotton fiber yarn; both yarn 1 and yarn 2 may comprise graphene modified nylon fibers.
Specifically, cotton fiber, bamboo pulp viscose fiber and graphene modified nylon fiber can be mixed according to the following ratio of 2-3:5-8:4-8 weight ratio of yarn 1 and yarn 2 were spun on a spinning machine. The prepared yarns 1 and 2 are woven on knitting equipment, and the used knitting equipment and weaving parameters can be as follows: the single-sided circular knitting machine has a machine number of 60-80, a cylinder diameter of 845-860mm and a rotating speed of 18-24r/min.
S2, performing alkali-oxygen cold stacking treatment on the cloth blank to improve the whiteness of the cloth blank and obtain a cold stacking cloth blank;
s3, carrying out tentering whitening treatment on the cold pile cloth blank to obtain a dyed cloth blank;
s4, steaming and softening qualitative treatment are carried out on the dyed cloth blank, so as to obtain a surface fabric;
s5, obtaining cool sense lining fabric;
s6, fixing the surface layer and the cool sense lining layer to obtain the ice silk cool sense fabric.
Specifically, the processing technology of the ice silk cool feeling fabric in the embodiment of the application may include: rolling amylase inactivation stacking, water washing, alkali-oxygen cooling stacking, water washing, tentering whitening, steaming, rolling water shaping, softening shaping (non-ironing and softening), calendaring, preshrinking and finished product inspection.
Specifically, in the enzyme padding and stacking process, the formula of the inactivated cold stack working solution comprises the following components: amylase 5-6 g/L, caCl:12-20.5g/L, 1-2g/L of penetrating agent, and can be subjected to a two-to-two padding process, and finally, thermal insulation stacking is carried out for 6-7 h.
Specifically, in the water washing process, after amylase stacking, substances such as maltose, cyclodextrin, glucose and the like are decomposed on the grey cloth, products after starch decomposition can be washed out through the water washing, and meanwhile, a certain amount of weak acid such as oxalic acid is added into a water washing tank, so that metal ions contained on the grey cloth can be complexed, and oxidation holes of the fabric in a cold stacking process are avoided.
As an alternative embodiment, the alkali-oxygen cold-stack treatment comprises three-padding and three-padding, the total rolling surplus is 70-85%, and the reagent of the alkali-oxygen cold-stack comprises: naOH:8.5-9.2g/L, hydrogen peroxide: 13.2-14.5g/L, 8-9g/L of hydrogen peroxide stabilizer and 6-7g/L of penetrant.
Specifically, during cold pad-batch oxygen bleaching, the consumption of alkali and hydrogen peroxide is required to be paid attention to, the excessive consumption of alkali can cause the falling of sericin in viscose fiber in the fabric and graphene modified nylon fiber can cause the graphene particles in the fabric to become fragile and fall off, so that hygroscopicity is influenced, and meanwhile, the shrinkage is influenced, so that the excessive shrinkage is caused, and the properties of the fabric are influenced; meanwhile, the alkali consumption has a certain influence on the printing color yield of the regenerated cellulose fiber, and the alkali consumption is too small, so that the printing color yield is low.
As an alternative embodiment, the tenter whitening treatment agent includes a cellulose whitening agent: 1-1.7g/L, 12-16g/L urea and a denaturant: 3-6g/L.
Specifically, the tentering whitening bamboo pulp viscose fiber has a compact cortex structure, which is determined by a spinning forming process, the graphene modified nylon fiber has large hydrophilic groups and raised particles, in order to enable dye molecules to better pass through the cortex to reach a fiber core layer, urea or urea substitutes (reducing ammonia nitrogen emission) or denaturants can be used for preprocessing the fabric, the cortex structure of the viscose fiber is puffed in advance, the cortex structure and the hydrophilic groups are reserved to the greatest extent, so that the fabric still retains the characteristics after being processed, and the fabric has a cooling feel when in use.
Specifically, the denaturant can be polyethylene glycol, fatty alcohol polyoxyethylene ether and fatty amine polyoxyethylene ether as main components.
As an alternative embodiment, the time of the steaming treatment is 20-28min, the temperature of the steaming treatment is 98-101 ℃, and the relative humidity of the steaming treatment is 80% -90%.
Specifically, due to the cortex structure of the bamboo pulp viscose fiber, the cortex can be puffed by properly prolonging the steaming time, so that the dye can be conveniently diffused into the fiber, the utilization rate of the dye is improved, the graphene modified nylon fiber is dyed, and the color fastness is improved.
As an alternative embodiment, the softness qualitative treatment employs a three-step process comprising: pre-baking, drying and baking.
Specifically, as the mass of the fabric per unit area is larger and the fabric is thicker, the three-step method can be adopted for production, the pre-baking can avoid the reaction of substances in the fabric to generate toxic substances, the drying is helpful for improving the color fastness and protecting sericin and surface raised particles in the fabric in a gradual shaping manner, and the baking is helpful for shaping the fabric; the soft qualitative treatment effects comprise non-ironing and soft, and the fabric has good hydrolysis resistance and better washing resistance after non-ironing finishing. Because the wash-and-wear finishing agent possibly contains N-methylol compounds, formaldehyde is inevitably generated in the production process, a small amount of urea or other substances can be added to absorb the formaldehyde, but when the urea is used in an excessive amount, the cloth cover is yellowing. Other wash-and-wear finishes that do not produce formaldehyde can be used. In addition, under the acidic catalysis condition, the modified graphene nylon fiber is easy to denature again, the time of the fabric in an acidic environment is shorter and is 5-15s, and in order to prevent the non-ironing finishing agent from migrating to form surface resin during pre-baking or to prevent part of resin from self-crosslinking to generate free formaldehyde, the setting temperature is not too high, and the fabric is ensured to be dried 7-8. Meanwhile, in order to allow the resin to sufficiently permeate into the interior of the fabric, a small amount of a permeation agent may be added.
As an alternative embodiment, the preparation method of the graphene modified nylon fiber includes:
mixing nano graphene particles, an adhesive modifier and an adhesive spinning solution to obtain a cellulose membrane,
refining the cellulose film to obtain cellulose composite graphene particles less than or equal to 0.8 um;
and mixing and granulating the cellulose composite graphene particles and nylon to obtain graphene modified nylon fibers.
Specifically, the components of the adhesive modifier comprise: ethanol, aluminum hydroxide, lecithin and viscose solution; the concentration of the ethanol may be 30-40%; the addition amount of the aluminum hydroxide in the viscose modifier is 0.5-3% of the mass of the ethanol solution.
