The Key Technologies Of Moisture Absorption And Dry-fast Knitted Fabric Online Production

Moisture absorption and dry-fast knitted fabric with superior properties are welcomed by the consumers. At pres ent, the tradition al method of production m oisture absorption and dry-fast knitted fabric is that the ya rn is slacked winding firstly, and the m ass is interposed dye vat for doing the water repellent treatment, and then drying, winding, knitted and finished. The method is not only process complicated, high cost and environment pollution, but also the yarn has the problem of unevenness of water repellent treatment. This problem has plagued the majority of enterprises, so the development of the moisture absorption and dry-fast knitted fabric properties is not high. In order to solv e the problem of the yarn unevenness of water repellent fundamentally, a online m ethod production is proposed by th is project. Through making additive tank and baking oven, the method of online production is once completed by the yarn water repellent treatm ent and woven. Fi rst of all the additive tank and baking oven are designed, and then the best agent concentration of water repellent treatment for the yarn is discussed, and finally the developm ent of mois ture absorption and dry-fast knitted fabric using online m ethod and traditional m ethods of development of moisture absorption and dry-fast knitted fabric are test and analyzed in contrast.First of all the additive tank and baking oven has been designed, and then the liquid rate of yarn and yarn tension and other factors have been analyzed to verify the reasonableness of the device, and further the device has been ti nker up or modified, fi nally, the last in the verification of additive tank and bak ing oven is that, the liquid rate of yarn and yarn tension can meet the basic requirements for knitting, the device is reasonable.Using the self-made device the raw cotton, boiled cotton, raw m odal and boiled modal have been taken water repellent treatment, the performance of the four yarns before and after treatment have been analyzed, the best fini shing agent concentration has been discussed, namely the best effect of the yarn water repellent which the concentration of finishing agent is about 9g/L for boiled cotton, raw modal and boiled modal, 11g/L for raw cotton.These four yarns have been developed moisture absorption and dry-fast knitted fabric by using online m ethod, the physical properties, wicking, moisture absorption and dry-fast properties of these fabrics have been studie d. The result showed that the performance of moisture absorption and dry-fast knitted fabric has been developed by using online m ethod which can achieve the ef fect of moisture ab sorption and dry-fast knitted fabric by using traditional method.
