Description

Technical Field

[0001] The invention relates to the field of fabrics, and in particular to a method for preparing a deodorizing and warm-keeping fabric. Background Art

[0002] With the development of the clothing industry, consumers' requirements for the functionality and comfort of clothing fabrics are increasing year by year. The performance of traditional fabrics in daily wear, sports scenes and special environments can no longer fully meet the use needs. For example, light summer clothing requires higher breathability to reduce the feeling of stuffiness, outdoor clothing requires tensile durability and protective properties, and sportswear needs to have good elasticity and dynamic adaptability. In addition, people also have higher expectations for the beauty, softness and skin comfort of clothing.

[0003] Traditional clothing fabrics (such as cotton, polyester, nylon and other fabrics made of single fibers) often have difficulty in balancing the properties of moisture absorption, perspiration, deodorization and warmth retention. Fabrics with strong deodorization and breathability often have poor warmth retention. Therefore, existing fabric designs weave fibers that have the properties of moisture absorption, perspiration, deodorization or warmth retention together, so that the woven fabrics can theoretically have the effects of moisture absorption, perspiration, deodorization and warmth retention at the same time. However, this method of simply weaving different fibers together usually does not have outstanding properties in all aspects of the fabrics. The reason for this is not only that at the physical level, the difference in weaving methods will affect the warmth retention effect, but also at the chemical level, the woven grey cloth will be affected by various chemicals during the subsequent refining, washing and dyeing processes, which will hinder the original deodorization function of the fiber. In particular, different weaving methods will also cause the fiber to be affected by chemicals to different degrees, which is more difficult to control. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for preparing a deodorizing and thermal-keeping fabric. The deodorizing and thermal-keeping fabric has the advantages of moisture absorption, perspiration, deodorization, breathability, etc., and has good thermal insulation performance, and is suitable for use as thermal underwear.

[0005] In order to solve the above technical problems, the technical solutions adopted are as follows: A method for preparing a deodorizing and warm-keeping fabric, characterized by comprising the following steps: (1) Braided grey fabric: the first yarn, the second yarn and the third yarn are braided according to a twelve-way circular braiding method; wherein the first yarn is a 50D / 72F moisture wicking polyester yarn, the second yarn is a 60S / 1 blended yarn spun from fine cotton and modal fiber, and the third yarn is a 20D Japanese Asahi Kasei spandex; (2) Pre-shape the grey cloth; (3) Refining is performed according to whether the grey cloth needs to be bleached. The grey cloth that needs to be bleached is refined in method A: (3-A01) non-ionic refining agent and H2O2 bleaching agent are added to purify and bleach the grey cloth at the same time; (3-A02) the refined and bleached grey cloth is washed with water, then acid-base neutralization is performed, and then H2O2 is removed; the grey cloth that does not need to be bleached is refined in method B: (3-B) non-ionic refining agent is added to purify the grey cloth; (4) Wash the grey cloth for the first time; (5) Dyeing the polyester in the grey cloth with disperse dyes; (6) Wash the grey cloth twice; (7) Determine whether the grey cloth after the second washing needs to be reduced. The grey cloth with a light color after the second washing does not need to be reduced. It can be directly washed with a non-alkaline soap and then washed three times. The grey cloth with a dark color after the second washing is reduced by a reducing agent other than the thiourea dioxide series reducing agent. After the reduction treatment, acetic acid is used for the initial acid-base neutralization and then washed three times. (8) Dyeing the cotton in the grey cloth with reactive dyes; (9) Use a fixing agent to fix the color of the grey cloth; (10) Soaping the grey cloth and performing secondary acid-base neutralization with citric acid; (11) Washing the grey cloth four times; (12) Heat setting the grey cloth.

[0006] When the deodorizing and warm-keeping fabric preparation method is used to prepare the fabric, the grey cloth prepared by step (1) has an excellent warm-keeping effect, and the Japanese Asahi Kasei spandex itself has a good ammonia absorption capacity and can play a deodorizing role. Since there are many factors that affect the deodorizing function of the grey cloth during the subsequent processing, among which, after the grey cloth is refined in step (3-A01) or step (3-B) and reduced in step (7), the charge distribution in the grey cloth fibers will be affected, thereby causing a great hindrance to the deodorizing function of the grey cloth; therefore, when citric acid is used for secondary acid-base neutralization, citric acid can react with the alkaline substances in the grey cloth fibers to restore the deodorizing function of the grey cloth (among which, thiourea dioxide series reducing agents will cause irreversible damage to the deodorizing function of the grey cloth, so in the reduction treatment, thiourea dioxide series reducing agents are not used as reducing agents), thereby ensuring that the fabric prepared by the above-mentioned preparation method can effectively retain the characteristics of various yarns, so that the fabric has the advantages of moisture absorption, perspiration, deodorization, breathability, etc., and has good thermal insulation performance, and is suitable for use as thermal underwear.

[0007] In the above step (7), the dyeing of the dark-colored grey cloth mainly relies on the mixing of the color paste and the grey cloth fibers, so that the fibers themselves naturally present colors, and the colors are bright and long-lasting, and are not easy to fade or fade. Therefore, after the dark-colored grey cloth is dyed with the polyester of the grey cloth, the permeability and adhesion of the dye can be improved by reduction treatment, ensuring that the dye can better penetrate into the fiber and better improve the dyeing effect.

[0008] The above-mentioned non-ionic series of refining agents can generally be phosphorus-free low-foam refining agents or non-ionic high-efficiency low-foam degreasing refining agents. According to the color to be dyed, disperse dyes can be directly dyed, such as directly using disperse orange, disperse blue, disperse yellow or disperse red, or the above-mentioned disperse dyes can be matched in a certain proportion to make disperse black, disperse green, disperse purple, etc. The above-mentioned non-alkaline agent for soaping can generally be enzyme detergent, acid soaping agent or neutral laundry detergent. The above-mentioned reducing agent can generally be sodium hyposulfite (sodium dithionite). The above-mentioned reactive dyes can generally be melamine dyes (this dye can be used for red dyeing), metaphenylenediamine dyes (this dye can be used for blue and indigo dyeing), resorcinol dyes (this dye can be used for black and dark dyeing), azo dyes (this dye can be used for orange and yellow dyeing), hydroxyethylaminomethyl acrylamide dyes (this dye can be used for yellow dyeing).

[0009] In the preferred embodiment, after the initial water washing in step (4) of the grey cloth to be bleached in step (3), if the grey cloth is white in color, citric acid is directly used for acid-base neutralization; then the cotton in the grey cloth is dyed with direct dyes, and the polyester in the grey cloth is dyed with disperse dyes, and the dyeing process adopts a one-bath method or a two-bath method; and after dyeing, steps (11) and (12) are directly performed. When the color of the grey cloth after bleaching is white, this method can be selected to restore the deodorizing function and dye, and steps (11) and (12) are directly performed, thereby reducing the process steps. When the grey cloth after bleaching is not white, the execution continues from step (4). Direct dyes can generally be diaminobenzylbenzene disulfonic acid direct dyes, etc.

[0010] In a further preferred embodiment, when dyeing the white grey cloth in the above step, a non-alkaline dye is used as the dye.

[0011] In a further preferred embodiment, when citric acid is used to neutralize the white grey cloth in the above step, the neutralization temperature is 80° C., the neutralization time is 20 min, and the citric acid concentration is 1.0-2.0 g / L.

[0012] In the preferred embodiment, in step (3-B), a non-ionic refining agent is added to scour the grey cloth. If no alkaline agent is added during scouring, the initial water washing in step (4) is directly performed; if an alkaline agent is added during scouring, acetic acid is required to neutralize the acid and alkali after scouring, and then the initial water washing in step (4) is performed. The alkaline agent can generally be an alkali-resistant scouring agent, a chelating dispersant or an alkali-resistant penetrant.

[0013] In the preferred embodiment, when bleaching is performed in step (3-A01), a metal ion blocking agent needs to be added. During bleaching, the metal ion blocking agent can prevent H2O2 from reacting with heavy metal ions to rapidly decompose, and can effectively maintain the stability of the bleaching solution.

[0014] In a preferred embodiment, the refining temperature in the step (3-A01) is 100° C. and the refining time is 40 min.

[0015] In a preferred embodiment, the refining temperature in step (3-B) is in the range of 80-90°C and the refining time is 20 minutes.

[0016] In the preferred embodiment, when the cotton in the grey cloth is dyed in step (8), if the dyeing process does not adopt the same-bath method, then in step (10), the grey cloth is first soaped and then subjected to secondary acid-base neutralization using citric acid; if the dyeing process adopts the same-bath method, then in step (10), the grey cloth is first soaped and then subjected to secondary acid-base neutralization using citric acid and then subjected to soaping.

[0017] In a preferred embodiment, when the secondary acid-base neutralization is performed in step (10), the neutralization temperature is 80° C., the neutralization time is 20 min, and the citric acid concentration is 1.0-2.0 g / L.

[0018] In a preferred embodiment, when the grey cloth is heat-set in step (12), citric acid at a concentration of 0.5-1.0 g / L is added. This method can further improve the deodorizing function.

[0019] In the preferred embodiment, in the twelve-way circular knitting method in step (1), the first way is that the second yarn and the third yarn are knitted together on the lower side for 1.2 feet, and the upper side does not move; the second way is that the first yarn and the third yarn are knitted together on the upper side for 1.2 feet, and the lower side does not move; the third way is that the second yarn is knitted alone on the lower side for 1.2 feet, and the upper side does not move; the fourth way is that the first yarn is knitted alone on the upper side for 1.2 feet, and the lower side does not move; the fifth way is that the first yarn and the third yarn are knitted together up and down and interlaced to move the lower leg; the sixth way repeats the fifth way operation; the seventh to tenth ways repeat the first to fourth ways operation; the eleventh way is that the first yarn and the third yarn are knitted together up and down and interlaced to move the high leg; the twelfth way repeats the eleventh way operation.

[0021] The beneficial effects of the present invention are as follows: the preparation method of the deodorizing and warm-keeping fabric has the advantages of moisture absorption, perspiration removal, deodorization, air permeability, etc., and has good warm-keeping performance, and is suitable for use as warm-keeping underwear.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: A method for preparing a deodorizing and warm-keeping fabric comprises the following steps: (1) Woven fabric: Figure 1 As shown, the first yarn, the second yarn and the third yarn are woven according to the twelve-way circular weaving method; wherein the first yarn is 50D / 72F moisture-wicking polyester yarn, the second yarn is 60S / 1 blended yarn spun from fine cotton and modal fiber, and the third yarn is 20D Japanese Asahi Kasei spandex; wherein the first yarn accounts for 48.9% of the grey cloth, the second yarn accounts for 41.8% of the grey cloth, and the third yarn accounts for 9.3% of the grey cloth. In the above second yarn, the proportion of fine cotton and modal fiber is 50% each.

[0024] like Figure 2 As shown, the subsequent processing flow of the grey cloth is as follows: (2) Pre-shape the grey cloth; (3) Refining is performed according to whether the grey cloth needs to be bleached. The grey cloth that needs to be bleached is refined in method A: (3-A01) non-ionic refining agent and H2O2 bleaching agent are added to purify and bleach the grey cloth at the same time; (3-A02) the refined and bleached grey cloth is washed with water, then acid-base neutralization is performed, and then H2O2 is removed; the grey cloth that does not need to be bleached is refined in method B: (3-B) non-ionic refining agent is added to purify the grey cloth; (4) Wash the grey cloth for the first time; (5) Dyeing the polyester in the grey cloth with disperse dyes; (6) Wash the grey cloth twice; (7) Determine whether the grey cloth after the second washing needs to be reduced. The grey cloth with a light color after the second washing does not need to be reduced. It can be directly washed with a non-alkaline soap and then washed three times. The grey cloth with a dark color after the second washing is reduced by a reducing agent other than the thiourea dioxide series reducing agent. After the reduction treatment, acetic acid is used for the initial acid-base neutralization and then washed three times. (8) Dyeing the cotton in the grey cloth with reactive dyes; (9) Use a fixing agent to fix the color of the grey cloth; (10) Soaping the grey cloth and performing secondary acid-base neutralization with citric acid; (11) Washing the grey cloth four times; (12) Heat setting the grey cloth.

[0025] When the deodorizing and warm-keeping fabric preparation method is used to prepare the fabric, the grey cloth prepared by step (1) has an excellent warm-keeping effect, and the Japanese Asahi Kasei spandex itself has a good ammonia absorption capacity and can play a deodorizing role. Since there are many factors that affect the deodorizing function of the grey cloth during the subsequent processing, among which, after the grey cloth is refined in step (3-A01) or step (3-B) and reduced in step (7), the charge distribution in the grey cloth fibers will be affected, thereby causing a great hindrance to the deodorizing function of the grey cloth; therefore, when citric acid is used for secondary acid-base neutralization, citric acid can react with the alkaline substances in the grey cloth fibers to restore the deodorizing function of the grey cloth (among which, thiourea dioxide series reducing agents will cause irreversible damage to the deodorizing function of the grey cloth, so in the reduction treatment, thiourea dioxide series reducing agents are not used as reducing agents), thereby ensuring that the fabric prepared by the above-mentioned preparation method can effectively retain the characteristics of various yarns, so that the fabric has the advantages of moisture absorption, perspiration, deodorization, breathability, etc., and has good thermal insulation performance, and is suitable for use as thermal underwear.

[0026] In the above step (7), the dyeing of the dark-colored grey cloth mainly relies on the mixing of the color paste and the grey cloth fibers, so that the fibers themselves naturally present colors, and the colors are bright and long-lasting, and are not easy to fade or fade. Therefore, after the dark-colored grey cloth is dyed with the polyester of the grey cloth, the permeability and adhesion of the dye can be improved by reduction treatment, ensuring that the dye can better penetrate into the fiber and better improve the dyeing effect.

[0027] The above-mentioned non-ionic series of refining agents can generally be phosphorus-free low-foam refining agents or non-ionic high-efficiency low-foam degreasing refining agents. According to the color to be dyed, disperse dyes can be directly dyed, such as directly using disperse orange, disperse blue, disperse yellow or disperse red, or the above-mentioned disperse dyes can be matched in a certain proportion to make disperse black, disperse green, disperse purple, etc. The above-mentioned non-alkaline agent for soaping can generally be enzyme detergent, acid soaping agent or neutral laundry detergent. The above-mentioned reducing agent can generally be sodium hyposulfite (sodium dithionite). The above-mentioned reactive dyes can generally be melamine dyes (this dye can be used for red dyeing), metaphenylenediamine dyes (this dye can be used for blue and indigo dyeing), resorcinol dyes (this dye can be used for black and dark dyeing), azo dyes (this dye can be used for orange and yellow dyeing), hydroxyethylaminomethyl acrylamide dyes (this dye can be used for yellow dyeing).

[0028] After the initial washing in step (4) of the grey cloth to be bleached in step (3), if the grey cloth is white in color, citric acid is directly used for acid-base neutralization; then the cotton in the grey cloth is dyed with direct dyes, and the polyester in the grey cloth is dyed with disperse dyes, and the dyeing process adopts a one-bath method or a two-bath method; and after dyeing, steps (11) and (12) are directly performed. When the color of the grey cloth after bleaching is white, this method can be selected to restore the deodorizing function and dye, and steps (11) and (12) are directly performed, thereby reducing the process steps. When the grey cloth after bleaching is not white, the execution continues from step (4). Direct dyes can generally be diaminobenzylbenzene disulfonic acid direct dyes, etc.

[0029] When the white grey cloth is dyed in the above steps, a non-alkaline dye is used as the dye.

[0030] In the above step, when citric acid is used to neutralize the white grey cloth, the neutralization temperature is 80° C., the neutralization time is 20 min, and the citric acid concentration is 1.0-2.0 g / L.

[0031] In step (3-B), a non-ionic refining agent is added to scour the grey cloth. If no alkaline agent is added during refining, the initial water washing in step (4) is directly performed; if an alkaline agent is added during refining, acetic acid is required to neutralize the acid and alkali after refining, and then the initial water washing in step (4) is performed. The alkaline agent can generally be an alkali-resistant refining agent, a chelating dispersant or an alkali-resistant penetrant.

[0032] During bleaching in step (3-A01), a metal ion blocking agent needs to be added. During bleaching, the metal ion blocking agent can prevent the rapid decomposition of H2O2 and heavy metal ions by catalytic reaction, and can effectively maintain the stability of the bleaching solution.

[0033] The refining temperature in step (3-A01) is 100°C and the refining time is 40 minutes.

[0034] The refining temperature in step (3-B) is in the range of 80-90°C and the refining time is 20 minutes.

[0035] When dyeing the cotton in the grey cloth in step (8), if the dyeing process does not adopt the same-bath method, then in step (10), the grey cloth is first soaped and then subjected to secondary acid-base neutralization using citric acid; if the dyeing process adopts the same-bath method, then in step (10), the grey cloth is first soaped and then subjected to secondary acid-base neutralization using citric acid and then soaped.

[0036] When the secondary acid-base neutralization is performed in step (10), the neutralization temperature is 80° C., the neutralization time is 20 min, and the citric acid concentration is 1.0-2.0 g / L.

[0037] When the grey cloth is heat-set in step (12), citric acid at a concentration of 0.5-1.0 g / L is added. This method can further improve the deodorizing function.

[0038] In the twelve-way circular knitting method in step (1), the first way is that the second yarn and the third yarn are knitted together on the lower side for 1.2 feet, and the upper side does not move; the second way is that the first yarn and the third yarn are knitted together on the upper side for 1.2 feet, and the lower side does not move; the third way is that the second yarn is knitted alone on the lower side for 1.2 feet, and the upper side does not move; the fourth way is that the first yarn is knitted alone on the upper side for 1.2 feet, and the lower side does not move; the fifth way is that the first yarn and the third yarn are knitted together up and down and interlaced to move the lower leg; the sixth way repeats the fifth way operation; the seventh to tenth ways repeat the first to fourth ways operation; the eleventh way is that the first yarn and the third yarn are knitted together up and down and interlaced to move the high leg; the twelfth way repeats the eleventh way operation.
