Problems solved by technology

The disadvantages of this method are: first, there is aldehyde pollution, not green textiles; second, the antibacterial properties of chitosan are greatly affected by pH, and basically have no antibacterial properties under neutral conditions; third, there is no moisture retention, and the function is single and popularized low value
Although these two methods have utilized the antibacterial properties of silver, they have the defects of silver discoloration, poor durability and single function.

example 1

[0016] Formula: chitosan, dosage 5%; sodium pyrrolidone carboxylate, dosage 7%; silver acetate (CH 3 COOAg), dosage 2.4%; softener, 5%; water, balance; all are weight ratio.

[0017] Preparation process: first make chitosan into an 8% acidic solution, and the auxiliary solvent is inorganic acid or organic acid. Silver acetate (CH 3 COOAg), react for 30-60 minutes, then add sodium pyrrolidone carboxylate and react for another 60 minutes to obtain the mother liquor of moisturizer; finally, add 25% non-ionic softener (fatty acid polyoxyethylene ether), continue stirring for 15 minutes, and dilute with water When reaching the formula content, the humectant for textiles can be obtained.

[0018] Application process: test fabric, polyester-cotton plain weave; humectant dosage 10% (owf).

[0019] Technological process: polyester-cotton plain weave → double dipping and rolling (100% liquid content) → hot air drying (temperature 90°C-100°C) → packaging → production.

example 2

[0021] Formula: chitosan, dosage 3.6%; ammonium pyrrolidone carboxylate, dosage 10.5%; silver nitrate (AgNO 3 ), dosage 2.8%; sodium alginate 7.2%; water, balance.

[0022] Preparation process: first make chitosan into a 7% acidic solution, and the auxiliary solvent is inorganic acid or organic acid. Silver nitrate (AgNO 3 ), reacted for 50 minutes, then added ammonium pyrrolidone carboxylate and reacted for another 70 minutes, and finally added sodium alginate and reacted for 30-60 minutes to obtain the mother liquor of humectant. Finally, softener and adhesive are added or not added as required, and diluted with water to the formula content to obtain a moisturizer for textiles.

[0023] Application process: test fabric, pure cotton poplin; humectant dosage 10% (owf).

[0024] Technological process: pure cotton poplin cloth→two dipping and two rolling (liquid-carrying rate 100%)→hot air drying (temperature 90℃~100℃)→packaging→production.

example 3

[0026] Formula: chitosan, dosage 3.6%; sodium pyrrolidone carboxylate, dosage 10.5%; nitrate (AgNO 3 ) dosage 2.8%; sodium alginate 7.2%; water, the balance; all are weight ratios.

[0027] Preparation process: first make chitosan into 2% acidic solution, and co-solvent is inorganic acid or organic acid. Nitrate (AgNO 3 ), reacted for 70 minutes, then added sodium pyrrolidone carboxylate and reacted for another 55 minutes, and finally added sodium alginate and reacted for 40-60 minutes to obtain the mother liquor of humectant. Finally, softener and adhesive are added or not added as required, and diluted with water to the formula content to obtain a moisturizer for textiles.

[0028] Application process: test fabric, linen fabric; humectant dosage 5% (owf).

[0029] Technological process: linen fabric → double dipping and rolling (100% liquid content) → hot air drying (temperature 90 ° C ~ 100 ° C) → packaging → production.

Abstract

The invention relates to a textile moisturizer preparing method and meanwhile relates to an application technology of a textile moisturizer. Main components of the textile moisturizer comprise chitosan, a derivative thereof, a silver salt and a pyrrolidone carboxylate. The preparing method includes following steps: (1) preparing an acidic solution from the chitosan; (2) adding the silver salt to carry out a reaction, adding the pyrrolidone carboxylate to continuously carry out a reaction to obtain a mother liquid; and (3) finally adding a softening agent and adding water for dilution to obtain the textile moisturizer. The textile moisturizer is used for manufacturing textiles having an anti-bacterial moisturizing function. The textile moisturizer is better than chitosan in an anti-bacterial performance. The textile moisturizer has an excellent moisturizing function since the textile moisturizer contains the main components of natural moisturizing factors, so that the textiles manufactured with the textile moisturizer has the anti-bacterial moisturizing function. The textile moisturizer can be used in skin care products, can be biologically degraded, belongs to an environmental-friendly functional moisturizer, and can achieve not only excellent economic benefit but also excellent social benefit.

Description

Technical field: [0001] The invention relates to a formulation and preparation process of a textile moisturizer mainly containing multi-component modified chitosan for producing moisturizing or antibacterial skin care functional textiles, that is, a preparation method of a textile moisturizer. technical background: [0002] Green consumption promotes the research and development of green functional textiles. The use of marine natural biological materials chitosan, modified chitosan, alginic acid and salts to prepare environmentally friendly additives has opened up a new way for the development of green functional textiles. [0003] In daily life, all kinds of textiles are a good place for the survival and reproduction of microorganisms and an important source of disease transmission. At the same time, people have higher and higher requirements for the comfort of home textile products and clothing, so the research on antibacterial and moisturizing of textiles is extremely imp...
