Description
Technical field
The invention belongs to textile field, in particular it relates to a kind of waterproof antistatic yarn and its production technology.
Background technology
Yarn is the product that certain fineness is processed into various textile fabrics, for weaving cotton cloth, rope making, line processed, it is knitting and thorn
Embroider etc..
Yarn is divided into：1. staple yarn, by chopped fiber（Atural staple fibre or chemical fibre staple）Formed through spinning processing, point
Ring spun yarn, open-end-spinning, yarn etc. is picked up certainly.2. continuous filament yarn, such as natural silk and chemical-fibres filaments, divide twist or not twist, light
Sliding long filament or modified continuous filament etc..3. chopped fiber and continuous filament yarn combination yarn, such as polyester-cotton blend filament core-spun yarn etc..Line is by two strands or two
More than stock single thread simultaneously closes twist and forms.
The classification of yarn is a lot, and general sorting technique is only introduced here：
A）Can be divided into by spinning process classification：Combed yarn and general comb yarn, semi-combed yarn
B）Can be divided into by dyeing and finishing and the post-processing classification of yarn：Raw white yarn, bleached yarn, dyed yarn, burn up yarn, mercerising yarn etc..
C）By the thickness of yarn（Yarn count）Classification, such as low count yarn, medium count yarn, fine-count yarn and high grade cotton yarn.
Wherein, blending（It is fine）Yarn, also known as blending or twisted union yarn line, the yarn being made up of two or more fiber,
Such as polyester cotton mixed yarn, hair/wash mixed yarn, hair/nitrile mixed yarn, wash/glue/nitrile mixed yarn, real silk/cotton yarn twisted union yarn.Have two
Plant the staple yarn that the mixing of above chopped fiber is spun into, referred to as mixed yarn；And combined by two or more filament yarns（As twisted）Into
Yarn, is mixed fiber yarn.
Scribbled is due to combining the characteristic of multiple fiber so that yarn is provided simultaneously with multiple performance.But it is existing mixed
Although yarn mixes two kinds of characteristic fibers, two kinds of speciality of fiber cannot be given full play to, it is difficult to realize causing yarn tool
The purpose of standby multiple efficacies.
