Problems solved by technology

It has many advantages, strong chemical corrosion resistance; thermal conductivity is worse than wool, so it has strong heat preservation; high electrical insulation and flame retardant; the strength of polyvinyl chloride is close to that of cotton, and its elongation at break is greater than that of cotton. Cotton is good, and its abrasion resistance is stronger than cotton; polyvinyl chloride has rich raw materials and short production process, which is the lowest production cost among synthetic fibers; the disadvantage of polyvinyl chloride is also relatively prominent, that is, extremely poor heat resistance
[0004] At present, the thermal insulation performance of the existing polyvinyl chloride and cotton fiber blended yarn needs to be improved, and its performance is not perfect, and it does not have the ability to sterilize and deodorize and resist ultraviolet rays
In the soaking process in the textile industry, if the yarn is directly immersed in the soaking liquid, it is easy to cause problems of entanglement and uneven soaking, which will affect the soaking effect

Embodiment 1

[0044] A production process of polyvinyl chloride and cotton fiber blended yarn, which is prepared by the processes of drawing, roving, spun yarn, post-processing, and soaking after the polyvinyl chloride and cotton fiber are respectively cleaned and carded, and the cotton fiber is Bamboo fibers are added, and polyolefin elastic fibers are added in the polyvinyl chloride fiber; its production process specifically includes the following steps:

[0045] a. Cotton sliver making: kapok fiber and bamboo fiber are selected, mixed, and then cleaned and combed in turn to obtain primary sliver; the primary sliver is soaked in polyurethane coating solution for 40 to 60 minutes, and then passed through Washing and drying to obtain cotton slivers;

[0046] b. Manufacture of chemical fiber sliver: take the hollow filaments of polyvinyl chloride fiber and polyolefin elastic fiber respectively, after mixing, make cotton rolls through the cleaning process, and then make chemical fiber sliver ...

Embodiment 2

[0056] A kind of production technology of polyvinyl chloride and cotton fiber blended yarn, its difference with embodiment 1 is:

[0057] The drying temperature in step a is kept at 80°C.

[0058] In this embodiment, the polyurethane coating liquid in step a includes 20 wt% polyurethane, 75 wt% organic solvent, 2 wt% fluorine-containing water repellent, and 3 wt% stearyl alcohol.

[0059] In this embodiment, the organic solvent is dimethylformamide.

[0060] Others are the same as embodiment 1.

Embodiment 3

[0062] A kind of production technology of polyvinyl chloride and cotton fiber blended yarn, its difference with embodiment 1 is:

[0063] The drying temperature in step a is kept at 85°C.

Abstract

The invention discloses a production process of polyvinyl chloride and cotton fiber blended yarn, which belongs to the field of textile technology. After the polyvinyl chloride and cotton fiber are respectively cleaned and carded, the processes of drawing, roving, spun yarn, post-processing and soaking are carried out. The cotton fiber is made of kapok fiber, which is mixed with bamboo fiber to make a sliver and dipped in polyurethane coating solution; polyolefin elastic fiber is added to the polyvinyl chloride fiber; the spun mixed yarn is also Soak with a solution containing silver ions and aluminum ions. The soaking device is equipped with a fixed roller row and a moving roller row. They work together to keep the yarn in a tight state, which is conducive to promoting uniform soaking and improving soaking. Effect; the present invention is also provided with an automatic threading mechanism without manual operation. The polyvinyl chloride and cotton fiber blended yarn provided by the invention has excellent thermal insulation performance, sterilization and deodorization performance and ultraviolet resistance; the provided yarn soaking device can improve the soaking effect and efficiency.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a production process of polyvinyl chloride and cotton fiber blended yarn. Background technique [0002] The biggest advantage of cotton fiber is its spinnability. The natural twist makes the cotton fiber have a certain wrapping force, which is beneficial to the spinning process. Cotton fiber has good hygroscopicity, warmth retention and wear resistance, and the moisture regain rate reaches 8.5%. It has no static electricity, good moisture absorption and perspiration, and is relatively close to the human body. The clothes made of it are comfortable to wear and have no pilling phenomenon. , soft to the touch; alkali resistance is not acid resistance, excellent alkali resistance, generally without any damage; cotton has excellent dyeing performance, easy to dye; under humidity, the strength of cotton fiber will increase by 10%, but the humidity is too high When low, the strength i...
