According to the present invention, it is possible to effectively prepare a highly elastic knitted product with a non-elastic yarn without using expensive elastic yarn.
The polyurethane elastic yarn comprises: an elastic yarn comprising a polyurethane mainly composed of a polymer diol and a diisocyanate; and a polymer of a compound having a sulfonate group contained in the elastic yarn.
Means for introducing the elastic yarn of said second spool (R2) in said interlacing jet (19) are also provided.
The polyurethane-urea elastic yarn manufactured by the method exhibits high power and a textile using the elastic yarn exhibits high power.
The stitching material is preferably an elastic yarn.
The covered elastic yarn (2) is stretched at a given stretch ratio and inserted, in the stretched state, into the first low-stretch yarn (3) so as to be united therewith.
The stocking section is knitted at least substantially of a core-spun yarn with an elastomeric core and a twisted fiber sheath and includes elastomeric threads integrated into the stretch yarn knitting.
Each resilient member comprises a resilient wire and a protective jacket.
The tubular bands (13) obtained are knitted bands with at least one inelastic thread and at least one bare elastic thread.
The elastic strand also includes at least one outer strand, where the outer strand is wound around the elastic core.
There is disclosed knitting, comprising a plated elastic thread (11).
The resilient wire support (14) is coupled to the block assembly (12) with each resilient wire support passage (66) aligned with one block assembly passage (20).
At least one transverse elastic thread may also be provided.
The upper section of each leg opening is elasticized by at least one arcuate elastic thread.
The elastic thread (3) is attached to the peripheral edge (8) of the flexible film (2) by a channel (5) formed of the flexible film (2) around the elastic thread (3).
We have determined that strength characteristics of elastic strand improve when the strand is heated.
Covering yarn using this elastic polyurethane yarn as a core.
The article is made of a stretchable warp fabric the ground texture of which is knitted with a non-elastic yarn and into which an elastic yarn of 231 dtex or less is inserted.
Thus, the present invention is directed to improving strength characteristics of an elastic strand by heating the strand.
A method is provided for winding an elastic yarn into a cylindrical substantially straight-ended yarn package.
In this way, a subsequent feed is obtained which permits the tension of the elastic thread to be released.
elastic yarn means any textile yarn that is comprised of an elastomer that may be covered with another yarn; (fil élastique)
