Lace has various styles and quality, is widely applied to the clothing industry and is popular with fashionable people. Lace T-shirts, lace skirts and lace vests can help women to make a unique airy lady shape, and nowadays, lace is successfully used as a fabric by shaking clothes accessories. The lace not only becomes an ornament of female love, but also becomes a civilization and a culture embodiment. Therefore, the lace is widely applied to daily life of people, in particular to a brocade cotton edge lace fabric which is mainly used for making high-grade dress and suit products by using a large fabric.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the technical means in detail, the following detailed description is given with reference to specific embodiments. The embodiments of the present invention are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.

In an embodiment of the present invention, there is provided a transfer tie-dyeing method comprising the steps of:

Different from the prior art, the technical scheme provides the transfer tie-dyeing method, the traditional tie-dyeing method and the transfer dyeing method are combined, the dye (the pattern and the color) of the transfer medium can be transferred to the grey cloth by only bundling the transfer medium into a preset pattern and carrying out transfer dyeing, the dye utilization rate and the color reproducibility are improved, the operation is convenient, and the process is controllable. Through the white leaving treatment, not all dip dyeing is needed, so that the white leaving effect is generated, the special pattern can be obtained by matching with a dyeing area, and the expression form and the process means of the tie-dyeing pattern are enriched. For example, the grey cloth to be dyed can be divided into a color area and a dye-resistant area according to design requirements, so that the whole dip dyeing is not needed, a white space effect is generated, and abundant and variable texture patterns are presented. The grain texture pattern cannot be pricked by the traditional rope tie-dyeing technology, and the transfer tie-dyeing method is developed on the basis of inheriting the traditional method.

In a further embodiment, the raw material components of the brocade cotton edge gray fabric comprise, by mass, 20% -40% of chinlon and 80% -60% of cotton.

In a further embodiment, the dye liquor is a reactive dye. The cotton component in the brocade cotton edge grey cloth is dyed by adopting the reactive dye, and the cotton component accounts for 60-80 percent of the total components, so the cotton component can exist continuously or in a larger area, and the patterns and the colors transferred to the brocade cotton edge grey cloth can be more concentrated or occupy a larger area. Meanwhile, the reactive dye does not dye the nylon component, so the white part can generate a white leaving effect, and the white leaving part can play a role in embellishing and coordinating because the nylon component accounts for 20-40% of the total components, so that attractive patterns and colors are set off, and the soldiers cannot take the lead.

In a further embodiment, the transfer medium is an air layer cloth sheet made of polyester material. The terylene air layer cloth piece has certain elasticity, can absorb dye liquor, simultaneously, the reactive dye can not be dyed, and can be reused after being cleaned. If other materials such as cotton are used, the cotton fiber itself absorbs water, which affects the dyeing operation, and the cotton fiber is soft and difficult to form, and is dyed by reactive dyes, so the cotton material is not suitable for use. For another example, the air layer made of nylon material is used as a transfer medium, and the defects of soft and unformed hand feeling also exist. Therefore, the dacron air layer cloth piece is most suitable as the transfer medium of the invention in the aspects of hand feeling, thickness, water absorption and the like.

In a further embodiment, the terylene air layer cloth sheet has the specification of 70-100 cm long, 15-20 cm wide and 2-5 mm thick. If the terylene air layer cloth piece is too large, the operation is not good when the terylene air layer cloth piece is held in the hand; if the thickness is too thin, the hand feeling is soft and the forming is difficult; if the thickness is too thick, the operation is inconvenient. After a plurality of tests and adjustments, the dacron air layer cloth piece with the length of 70-100 cm, the width of 15-20 cm and the thickness of 2-5 mm is found to have the best operability.

In a further embodiment, after the transfer tie-dyeing in the step (3) is completed, the following steps are further included: stacking, drying, washing, soaping, dehydrating, spreading and shaping finished products.

In a further embodiment, the stacking comprises: and (3) bundling the dyed grey cloth by using a plastic film, and stacking for 12-24 hours at the temperature of 25-35 ℃. The dyed grey cloth is wrapped by the plastic film, so that dye liquor on the outer surface can be prevented from evaporating to influence coloring; the color difference between the head and the tail can be effectively prevented by piling for 12-24 hours at 25 ℃. In a specific embodiment, the stacking time range can be adjusted correspondingly according to the color depth of the dyed grey cloth, the stacking time with a little light color is shorter, and the stacking time with a little dark color can be prolonged properly.

In a further embodiment, the drying comprises: drying at 90-100 ℃ according to the speed of 20-25 m/min. And drying is carried out after stacking, so that the generation of head-tail color difference can be further prevented.

In a further embodiment, the water wash comprises: and washing the stacked and dried dyed grey cloth with cold water at normal temperature for 10min, draining, washing with cold water at normal temperature for 20min, draining, and continuously washing with water for 2-4 times. By doing so, the occurrence of staining of the left white portion can be effectively prevented.

In a further embodiment, the soaping comprises: adding 0.5-2 g/L soaping agent, and soaping for 20min at 70-90 ℃. Through soaping, the color fastness can be ensured to meet the standard requirement. In a specific embodiment, the dosage of the soaping agent and the soaping temperature can be correspondingly adjusted within the range according to the color depth of the dyed grey cloth, and the soaping agent with a light color is less and the temperature is lower; if the color is darker, the dosage of the soaping agent is larger and the temperature is increased. In the specific embodiment, the soaping agent can be selected from anti-staining soaping agent DM-1572 produced by Guangdong Germany fine chemical industry Co., Ltd, white soil anti-staining soaping agent TF-230A produced by Zhejiang chemical industry Co., Ltd, strong anti-staining soaping powder TF-230F produced by Zhejiang chemical industry Co., Ltd, or cotton soaping agent CL-780B produced by Xiamen Banglada printing and dyeing materials Co., Ltd.

In a further embodiment, both said water washing and said soaping are performed in an overflow dyeing machine. By adopting the overflow dyeing machine, the high-pressure water flow can be utilized to drive the grey cloth to circularly operate in the dye vat, the impact force of the high-pressure water flow is large, and dyes which are attached to the surface of the grey cloth and are not dyed can be rapidly washed clean.
