Description

Technical Field

[0001] The invention relates to the field of fabric production technology, and in particular to a production technology of antibacterial, mite-removing, cool-feeling, degradable and environment-friendly knitted fabric. Background Art

[0002] Nowadays, with the continuous progress of science and technology and the continuous improvement of living standards, people have new demands for the performance of clothing. From the past emphasis on covering the body and keeping warm to the later emphasis on fashion, people have begun to pay attention to the functionality and environmental protection of fabrics today. In recent years, humans have used a large amount of fossil fuels and cut down forests, causing a sharp increase in the concentration of gases such as carbon dioxide in the earth's atmosphere, resulting in a "greenhouse effect" and an increase in the global average temperature. Due to global warming, the summer is hotter, and humans have increased the use of refrigeration equipment such as air conditioners, making the "greenhouse effect" more serious, creating a vicious cycle. In this context, people have put forward a demand for cool and comfortable clothing, and products with excellent cooling performance have been favored by people. Knitted products have long been loved by consumers due to their excellent comfort and aesthetics. In the development and application of the functionality of knitted fabrics, due to the many advantages of synthetic fiber raw materials, many types and good wearability, combined with the advantages of knitted fabrics, it has better wearability and market potential.

[0004] In order to solve the above problems, the technical solution adopted by the present invention is: a production process of antibacterial, anti-mite, cool, degradable and environmentally friendly knitted fabrics, the production process is as follows: weaving → dyeing → dehydration → widening and drying → shaping → finished product, characterized in that:

[0005] (1) Weaving: Use a knitting single-sided circular knitting machine, use a weft-knitted single-sided plain cotton cover yarn structure, use 50-60S pure cotton yarn for the veil, and use 50D / 36F-75D / 36F antibacterial cool yarn PLA from Toray Company of Japan, so that each cotton yarn is covered with an antibacterial cool yarn on the reverse side;

[0006] (2) During dyeing: A. Immerse the fabric in a solution containing 3-4 g / L oxygen bleaching aid and 5-6 g / L hydrogen peroxide, then add 0.04-0.05 wt% of brightener and 0.5-1 wt% of cotton brightener to the solution, then heat to 95-100°C, dye for 40-50 min to dye the cotton fiber, and add 1-2 g / L of high-concentration degreasing agent and 1-2 g / L of high-concentration penetrant to the aqueous solution. After dyeing, add 0.55-1 g / L of citric acid for acid washing and neutralization, the acid neutralization temperature is 60-90°C, and the heat preservation time is 10-20 min; B. Add 5-6% of weak cationic film and 0.7-1 g / L of de-alkali agent, and soften the fabric and soak it in hot water for 30-40 min;

[0007] (3) During shaping: 4-5 g / L of a sweat-absorbing, quick-drying, and easy-to-clean finishing agent is added to the shaping machine rolling groove to prepare a finishing impregnation liquid, and the dried fabric is immersed in the finishing impregnation liquid water tank for modification treatment; after the modified fabric is rolled by a rolling mill, the temperature is set at 95-100° C., the wind pressure of the fan is 75-90 kPa, the shaping upper over-position is 25-35%, the shaping lower over-position is -0.5-0%, the door width is set at 160-190 cm, and the vehicle speed is 20-30 m / min.

[0008] Furthermore, the production process of the aforementioned antibacterial, mite-removing, cool, biodegradable and environmentally friendly knitted fabrics, wherein: in dyeing: oxygen bleaching agent 197 from Jiangyin Yicheng Chemical Co., Ltd., brightener HPS-D from Shaoxing Shangyu Mingzhou Dye Chemical Co., Ltd., cotton brightener C2 from Shanghai Angke Chemical Co., Ltd., high-concentration degreasing agent HD-809 and high-concentration penetrant 180 from Zhangjiagang Free Trade Zone Weida Chemical Trading Co., Ltd., weak cationic film V18 from Suzhou Liansheng Chemical Co., Ltd., and de-alkali agent AC from Shanghai Xirui Textile Technology Co., Ltd. are selected.

[0009] Furthermore, the production process of the aforementioned antibacterial, mite-removing, cool, biodegradable and environmentally friendly knitted fabric comprises the following steps: during shaping: the sweat-absorbing, quick-drying and easy-to-decontamination finishing agent FC-226 produced by Shanghai Xirui Textile Technology Co., Ltd. is selected.

[0010] Furthermore, the production process of the aforementioned antibacterial, mite-removing, cool, biodegradable and environmentally friendly knitted fabric includes: the knitting single-sided circular machine uses the Lida brand 34-inch 32 single-sided circular machine of Shanghai Xinshen Textile Machinery Co., Ltd.

[0011] Furthermore, the production process of the aforementioned antibacterial, mite-removing, cool, biodegradable and environmentally friendly knitted fabric comprises the following steps: after the dyeing and softening is completed, the fabric is dehydrated and stretched and dried at 90-100°C.

[0012] Furthermore, the production process of the aforementioned antibacterial, mite-removing, cool, biodegradable and environmentally friendly knitted fabric comprises: using a German Monforts brand model: MONFON828 TwinAir 10F shaping machine.

[0013] The advantages of the present invention are: environmentally friendly cotton fiber is used as the main yarn, and PLA degradable fiber with cool and antibacterial functions is used as the auxiliary yarn, and the prepared fabric has good hydrophilic properties through sweat-absorbing, quick-drying and easy-to-clean finishing, and can effectively absorb sweat on the skin. The sweat is effectively diffused to the outer fabric through the high moisture conductive fiber to keep the inner layer of the fabric relatively dry, reduce the adhesion effect between the human body and the fabric, and improve the comfort of the human body. The fabric also has the advantages of antibacterial and mite removal, instant cool feeling when touched, water washability, and good durability. DETAILED DESCRIPTION
