Description

Fabric, washing method thereof and worn leisure ready-made garment

Technical Field

The invention relates to the technical field of textile, in particular to a fabric, a washing method thereof and a worn leisure ready-made garment.

Background

With the global increase in the economic level of the world today, the demands of people for clothing, textiles, etc. are increasingly tending to be personalized and diversified. The significance of the clothing to people is also increasing, the clothing is no longer one way for our masks, and is one of important expression ways for modern people to pursue individuality and display themselves in trend. The worn leisure is a large class of personalized clothing, mainly products for fading the color of colored clothing, comprising the types of effects such as integral blushing, bone blushing and the like, wherein the integral blushing effect comprises integral uniform blushing, integral non-uniform blushing and the like.

The washing water of the old leisure ready-made clothes is mostly processed by adopting a processing principle of a fading mode, and particularly, the method mainly utilizes the stripping function of a strong oxidant or the friction and fading function of sand and stone to fade the colored ready-made clothes. Common fading washing water modes mainly comprise alkaline washing, acid washing, ozone stripping and the like. The alkaline washing, namely the alkaline water bath method garment fading washing process, needs a large amount of stripping agent and water in the fading washing process, has limitation under the current increasingly strict environmental protection production requirements, and is easy to generate the problems of staining, bone abrasion and the like for complex patterns such as cloth bumping, special auxiliary materials and the like. The acid washing is another traditional color stripping ready-made clothes washing process, and the process mainly comprises the steps of mixing a potassium permanganate solution with a certain concentration, sandy soil, stones and ready-made clothes in a machine for rolling friction, so that a large-area whitening effect is shown on the surface of the ready-made clothes. Compared with the alkaline stripping fading washing process, the washing process has the advantages of less water consumption, high stripping degree, more obvious blushing and residual old appearance, and better blushing effect especially on thick and heavy parts such as the bone position of the ready-made clothes. However, pickling has problems, such as that the diatomite carrier is a disposable consumable product, a large amount of solid waste is generated, and a large amount of dust is generated during production, which has adverse effects on workshop production environment and worker health. In addition, acid washing places a significant limitation on the dye and color, and does not produce a whitish wash appearance on any color and dye product. Ozone stripping is a non-aqueous environment-friendly fading washing technology, and the concentration and the treatment time of ozone gas can be adjusted to show different degrees of fading effects, but the stripping technology is non-selective stripping due to the gas circulation of ozone, so that the whole fading can be generally realized, and the personalized fading effect is difficult to realize.

In addition, the coating dyeing method of the ready-made clothes is another main mode for producing the residual leisure ready-made clothes in recent years, and the method mainly utilizes the characteristics of poor color fastness effect and easy elution and blushing of the coating dyeing so as to realize the technical effects of overall blushing and obvious bone position effect of the coating dyeing and blushing of the old clothes. However, the dyeing rate of the fading mode is low, and the color fastness is poor, so that a large amount of paint is required to be used in the paint dyeing process, the water pollution is large, and the production site is difficult to clean.

Thus, the conventional washing process of the worn casual garment has a certain technical limitation, and needs to be further improved.

Detailed Description

In order that the invention may be readily understood, a more complete description of the invention will be rendered by reference to the appended drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

In the invention, the technical characteristics described in an open mode comprise a closed technical scheme composed of the listed characteristics and also comprise an open technical scheme comprising the listed characteristics.

An embodiment of the present invention provides a fabric. Further, the washing method of the fabric includes the following steps S110 and S120.

Step S110: and (5) absorbing the coloring solution by using a washing auxiliary material.

Wherein the washing auxiliary material comprises granular vinyl acetate-ethylene copolymer. The vinyl acetate-ethylene copolymer has larger specific surface area, better adsorption performance on the coloring solution, irregular appearance of the granular vinyl acetate-ethylene copolymer, and certain bouncing property, and when the granular vinyl acetate-ethylene copolymer is mixed with the fabric to be treated and is used for washing water in a washing machine, the vinyl acetate-ethylene copolymer serving as the washing water auxiliary material moves more freely in the washing machine and can be in 'punctiform' contact with the contact surface of the fabric to be treated, so that natural punctiform appearance patterns are formed on the surface of the fabric, and the natural punctiform appearance patterns enable the fabric to show the overall whitening effect. It is understood that the overall blushing effect referred to in the present embodiment includes an overall uniform blushing effect and an overall non-uniform blushing effect.

Further, the particle size of the washing auxiliary material is preferably 0.2 cm-3 cm. If the washing auxiliary material particles are too fine, washing auxiliary material remained in the washing machine after the washing process is finished is difficult to clean, and if the washing auxiliary material particles are too large, the washing effect is very uneven, and the overall whitening effect of the fabric is affected.

In this embodiment, an additive color is used to make the fabric have an overall whitening effect, and specifically, an additive color solution is used.

In a specific example, the raw materials of the additive color solution comprise white thermosetting resin, the white thermosetting resin is prepared into a solution to be absorbed by washing auxiliary materials, the white resin is transferred to the surface of the fabric along with the contact of the washing auxiliary materials and the fabric during washing, and the fabric is subjected to high-temperature fixation, so that the fabric has the overall whitening effect. Specifically, the white thermosetting resin includes an acrylic resin.

Further, the raw materials of the additive color solution can also comprise a catalyst, so that the white thermosetting resin can better react with the fabric under the action of the catalyst, the additive color fixation effect is firmer, and further, the improvement of color fastness is facilitated. In particular, the catalyst comprises an aziridine crosslinking agent.

It will be appreciated that the additive solution also includes a solvent. Specifically, the solvent of the additive color solution may be water which is commonly used, and further, soft water is preferable.

It will be appreciated that the additive solution needs to be formulated prior to use, and that a specific formulation method comprises the steps of:

the white thermosetting resin is mixed with the catalyst and the solvent.

It will be appreciated that the additive solution formed after mixing may also be filtered.

In a specific example, the mass concentration of the white thermosetting resin in the additive color solution is 10g/L to 600g/L. The mass concentration control of the white thermosetting resin can ensure that the fabric has a proper color adding effect, if the concentration is too low, the fabric cannot have an overall blushing effect, and if the concentration is too high, excessive color adding is easy to cause the fabric to be excessively white, and the fabric is hard and dry to feel and is difficult to soften. It is understood that the mass concentration of the white thermosetting resin in the additive color solution may be, for example, 10g/L, 30g/L, 50g/L, 90g/L, 100g/L, 120g/L, 140g/L, 180g/L, 200g/L, 210g/L, 250g/L, 280g/L, 300g/L, 320g/L, 3500g/L, 370g/L, 4000g/L, 410g/L, 450g/L, 480g/L, 500g/L, 550g/L, 600g/L, etc., without being limited thereto. Specifically, the mass concentration of the white thermosetting resin in the additive color solution is 100 g/L-500 g/L.

In a specific example, the mass concentration of the catalyst in the additive color solution is 10g/L to 50g/L. It will be appreciated that the mass concentration of the catalyst in the additive solution may be, for example, 10g/L, 20g/L, 30g/L, 40g/L, 50g/L, etc. Specifically, the mass concentration of the catalyst in the additive color solution is 40 g/L-50 g/L.

It will be appreciated that the ratio of the additive color solution to the wash water adjuvant in the blend formed in step S110 is also an important factor affecting the whitening effect of the fabric. In a specific example, the ratio of the volume of the additive color solution to the weight of the wash water adjunct is (0.05-0.3) L:1kg. In the range, the fabric can be ensured to have a good overall whitening effect, the excessive volume ratio of the coloring solution can cause the excessive liquid carrying rate of the washing auxiliary materials, the coloring solution can not be uniformly absorbed by the washing auxiliary materials, excessive heating solution can form obvious material drops on the surface of the washing auxiliary materials and the inner tank wall of the machine, and obvious water stain-like whitening defects can be formed on the surface of the fabric when the subsequent dry frying treatment is carried out; too low a volume ratio of heated solution may result in poor blushing. It will be appreciated that the ratio of the volume of additive colour solution to the weight of wash water adjunct may be, for example, 0.05L:1kg, 0.08L:1kg, 0.09L:1kg, 0.1L:1kg, 0.13L:1kg, 0.15L:1kg, 0.17L:1kg, 0.2L:1kg, 0.22L:1kg, 0.25L:1kg, 0.3L:1kg etc. Specifically, the ratio of the volume of the additive color solution to the weight of the washing auxiliary materials is (0.1-0.3) L to 1kg.

In a specific example, the step of adsorbing the additive color solution using the wash water adjuvant includes:

dividing the additive color solution into at least 3 batches, and sequentially mixing with the washing water auxiliary materials.

It can be appreciated that the additive color solution is divided into a plurality of batches of washing auxiliary materials for mixing, so that the adsorption effect of the washing auxiliary materials is more uniform, and more additive color solution can be adsorbed by the washing auxiliary materials as much as possible. Specifically, after the washing auxiliary material adsorbs the coloring solution, the liquid carrying rate of the washing auxiliary material in the saturated state is about 30%.

For example, in one example, the step of batch mixing may be: spraying 1/3 of the additive color solution onto the washing water auxiliary materials, and uniformly mixing; then spraying 1/2 of the rest color adding solution onto the washing water auxiliary materials, and uniformly mixing; and finally, spraying the rest coloring solution on the washing auxiliary materials, and uniformly mixing to finish the mixing. It will be appreciated that batch mixing may also be performed in other ways, not limited thereto.

It will be appreciated that step S110 described above is typically performed in a washer. Furthermore, a modified water washer is adopted, the inner container of the traditional water washer or roller dryer is usually provided with a plurality of drain holes for facilitating drainage, the drain holes can lead to loss of washing water auxiliary materials and coloring solution, and therefore, the drain holes of the inner container of the water washer can be sealed by plates such as a rubber plate or a steel plate. It will be appreciated that this step is not limited to being performed in a washer, but may be performed in other machines capable of performing the above steps.

It will be appreciated that step S110 may be performed in the modified washer, and after the additive color solution is sprayed onto the auxiliary washing materials, the modified washer may be operated to accelerate the mixing in order to uniformly mix the additive color solution and the auxiliary washing materials. In a specific example, the machine operating setting during mixing may be, for example, 20rpm to 30rpm, 30s to 5s, bi-directional rotation. It will be appreciated that other settings of the operating conditions of the machine at the time of mixing may also be made in connection with the actual situation, without being limited thereto.

It will be appreciated that in order to avoid that the water in the original modified washer influences the concentration of the additive color solution, the modified washer may be dried in advance before step S110. In one example of the present invention, a method of drying a modified washer is provided, and specifically, for example, clean and dry reuse cloth may be placed into the modified washer to allow the modified washer to operate for at least 20 minutes.

Step S120: and (3) dry-frying and color fixing the fabric to be treated by using the washing auxiliary material adsorbed with the coloring solution.

It can be appreciated that the addition amount of the fabric to be treated in the mixing of step S120 is closely related to the content of the washing auxiliary material and the additive color solution, and further, the addition amount of the fabric to be treated may be determined according to the content of the washing auxiliary material. In a specific example, the weight ratio of the washing auxiliary material to the fabric to be treated is 1 (0.2-5). After the fabric is subjected to dry frying and color fixing treatment within the weight range, the fabric can have a better overall whitening effect. It will be appreciated that the weight ratio of wash water adjunct to fabric to be treated may be, for example, 1:0.2, 1:0.6, 1:1, 1:1.2, 1:2, 1:2.5, 1:3, 1:3.8, 1:4.2, 1:4.5, 1:5, etc. Further, the weight ratio of the washing auxiliary materials to the fabrics to be treated is 1 (0.2-2).

In a specific example, the conditions of the dry-frying include: the rotating speed is 20 rpm-30 rpm, the time is 5 minutes-30 minutes, and the intermittent bidirectional rotation is realized. Intermittent bidirectional rotation herein refers to a period of time after each rotation and then a period of time after each rotation, and the rotation direction includes clockwise direction and anticlockwise direction, for example, 30s for each rotation and 5s for each rotation. It can be appreciated that the dry-frying time can be adjusted according to the preset blushing degree, and the longer the dry-frying time is, the more obvious the overall blushing degree is. Further, the rotation speed is 25rpm to 30rpm. Further, the rotation time is 5 minutes to 20 minutes. It will be appreciated that the dry-frying process may also be carried out in a modified washer.

It can be understood that before the fabric to be treated is treated, a layer of dry clean waste cloth can be paved on the surface of the washing water auxiliary material adsorbed with the coloring solution, so that the fabric to be treated can be effectively prevented from being directly contacted with the washing water auxiliary material in a static state before the dry frying treatment is started, and the fabric is prevented from generating defects.

In one specific example, the conditions for fixation include: the drying temperature is 90-110 ℃ and the drying time is 50-70 minutes. It is understood that the fixation treatment may be in-dryer treatment. It can be understood that the fabric after the dry-frying treatment can be taken out from the modified washing machine before the fixation treatment, the adhered residual washing auxiliary materials are removed, and then the fabric is put into a dryer for drying and fixation. It will be appreciated that this step is not limited to being performed in a dryer, but may be performed in other machines capable of accomplishing the above.

It will be appreciated that the method of washing the fabric may further comprise the step of washing the wash adjunct. Specifically, the washing step may be, for example, collecting the dried and fried washing auxiliary materials, placing the washing auxiliary materials in a conventional washing machine for washing with clear water, placing the washing auxiliary materials for standby after washing, and recycling the washing auxiliary materials. Further, the condition of washing with clean water may be, for example, washing at room temperature for 20 minutes to 60 minutes, dehydrating for 200 seconds to 300 seconds, and drying at 30 ℃ to 50 ℃ for 50 minutes to 70 minutes.

It will be appreciated that the fabric may also include steps of overdrying, drying, etc. after the fixing process.

It will be appreciated that the steps of overdrying, drying, etc. may be carried out by methods conventional in the art. After the fabric is washed by soft water, the floating color can be effectively removed, the hand feeling is improved, and the washing process is finished after drying.

By adopting the fabric washing method in the embodiment, the obtained fabric has the whole whitening effect, and the worn casual ready-made garment can be obtained after the fabric is processed.

Compared with the fading residual washing process in the traditional technology, the fabric washing method with the integral whitening effect has obvious advantages in the aspects of fabric quality, process environmental protection, industrial production and the like:

in the aspect of fabric quality, the strength loss of the fabric after washing process is not more than 5%, the appearance after home washing reaches 4 levels, and the color spectrum is more complete. The washing method provided by the invention does not need strong acid and alkali chemical treatment, does not have severe physical friction caused by diatom and pumice, and does not damage the strength of the fabric basically. The white thermosetting resin adopted in the raw materials of the additive solution has no limit on the dye type of the fabric, and can be suitable for processing technologies of fabrics with various colors, particularly medium and dark colors.

In the aspect of process environmental protection, the dry stir-frying and coloring process is a non-water bath processing mode, a large amount of industrial raw materials are not needed, water is less, sewage discharge is reduced, and the method is environment-friendly. And the used washing water auxiliary materials can be recycled, so that the raw materials are saved.

In the aspect of industrial production, the invention has less limiting conditions on production equipment, and can seal and reform the drain hole of the traditional water washing machine or roller dryer for production.
