Description
Technical field
The present invention relates to it is a kind of using short linen look fiber or yarn prepare flexible auxetic compound fabric process and
Purposes belongs to the preparation and use technical field of textile material and its composite material.
Background technique
Although staple fiber can prepare yarn at present, fabric is woven, its process is complicated, especially flaxen fiber.It is numb fine
Tie up between short, batch that difference is big, humidity is larger to strong influence further increases its difficulty of processing.Moreover, the short fibre of linen look
There is also difficulties in process for dimension, and product fault is more, and price is low, are the new technology shortcoming of product.Therefore, exploitation tool
There is the linen of new construction and new function, improving value-added content of product and performance has important meaning for the development of linen look fiber
Justice.Auxetic materials refer to the material with Negative poisson's ratio, i.e., material broadens when stretching perpendicular to draw direction, when compression
The phenomenon that material narrows is one of 21 century intellectual material.Fabric, which is prepared into auxetic cloth using auxetic structure, has potential answer
Use prospect.Report currently with auxetic structure preparation auxetic fabric is rarely seen.
The preparation of auxetic fabric can be woven using the progress of auxetic yarn, but effect is not obvious.Auxetic fabric is more at present
For knitted structure, Ugbolue (Ugbolue, Warner et al.2000, Ugbolue, Kim et al.2011) is according to Hook
Deng design concept devise by opening chaining and the warp knit structure that is bonded of insertion yarn.In recent years recklessly red equal scholars according to
The theory of the scholars such as Grima and Evans assigns the inward turning folded rectangular connected structure of knitted fabric, and having weaved has large scale
Stretching property fabric (Liu and Hu 2010, Hu, Wang et al.2011).2016, Steffens (Steffens,
Rana et al.2016) etc. attempt for the first time by using high-performance fiber develop auxetic structure knitting technology, by polyamide
(PA) and para-aramid (p-AR) fiber and its conjugate using knitted in flat knitting machine at purl.Ge Chaoyang (Ge,
Hu et al.2013) weaving three-dimensional woven fabric, it studies its compressive deformation mechanism for generating auxetic effect and its structural parameters is discussed
Influence to negative poisson's ratio.2014, Hu Hong etc. (Wang, Hu et al.2014) devised a kind of novel auxetic interval and knits
Object forms a kind of warp knit isolation structure of special geometry by space fabric and parallelogram, is a kind of novel
3D auxetic fabric, using compression and thermal finalization come fixed fabric structure, and material has good Memorability.Auxetic yarn and its
Fabric can be also used for preparing composite material, while auxetic textile is due to its special shearing rigidity, fracture toughness, resistance to compression trace
Property and the properties such as energy absorption, there are also special synclastic curvature so that auxetic materials be referred to as 16 intellectual materials of 21 century it
One, it is expected to be applied to many fields: auto industry, physical protection, aerospace, biomedicine and other national defences, thus
Making the R and D of auxetic materials has realistic meaning.But it can be used in the auxetic materials or auxetic yarn of large-scale production at present
Line and auxetic foam still are limited to knitted structure for the preparation of flexible auxetic textile fabric, if it is possible to solve auxetic fabric
Preparation problem, will open auxetic industrial textileization application gate.
But the manufacturing process for the auxetic fabric that these above-mentioned methods are related to is using the short fiber yarn or chemical fibre of spinning forming
Long filament, even with the long filament of particular/special requirement (such as diameter, elasticity, rigidity), ingredient requirement is high, to traditional flaxen fiber, tool class
It is totally unfavorable like the fiber (linen look fiber) of flaxen fiber length, the product development of the staple fiber of waste gas circulation recycling, it is bottle
Neck and weakness.Therefore, it is just extremely necessary that new construction, the novel technical method for the advantage for playing staple fiber are introduced.
Summary of the invention
