Description
Technical field
The present invention relates to textile auxiliary material technical field, and in particular to a kind of terylene warp knitting cloth covers the production technology of top bar.
Background technology
In order to ensure that the body-sensing of wearer is more comfortable, top bar is covered in bound edge suture at the inseam of cap body.Cover the effect of top bar
The top of the head suture friction for avoiding wearer is not only in that, also resides in and is engaged with seam, keep the top convex surface of cap body
Design radian, it is to avoid use and be cleaned multiple times for a long time, fold after deform.It is generally all-cotton fabric or cotton and its to cover top bar
He is made in synthetic fibers blending, of the prior art to cover the top face printed patterns of bar one in order to reach the effect of mark.But, on
State traditional crown bar deflection not enough, improved technical scheme uses terylene warp knitting cloth.But terylene warp knitting cloth is by pulling force effect
After can occur irreversible deformation, so as to cause pattern deformation or even to come off.Conventional fabric starching is handled to terylene warp knitting cloth
The improvement of tensile property is not obvious.Therefore, it is necessary to being arranged in the prior art as the sizing for the terylene warp knitting cloth for covering top bar
Technique optimizes improvement.
The content of the invention
It is an object of the invention to overcome defect present in prior art, there is provided the life that a kind of terylene warp knitting cloth covers top bar
Production. art, is that acrylic acid ester emulsion and lactide grafting are formed sediment by using main component using terylene warp knitting cloth and as base material
The typing finishing agent of powder is arranged, gained cover top bar warp-wise tensile property be improved significantly.
To realize above-mentioned technique effect, the technical scheme is that：A kind of terylene warp knitting cloth covers the production technology of top bar,
It is characterised in that it includes following steps：
S1：Terylene warp knit is arranged in the sodium hydroxide solution that mass fraction is 2~8%, is warming up to 80~95 DEG C of insulations
30~50min is reacted, terylene warp knitting cloth cleaning, drying is taken out；
S2：Cloth obtained by S1 is imported into padding finishing in typing finishing agent, heat cure must endure with all one's will fabric；
S3：Stiffening fabric obtained by S2 is cut into the strip of preset width along warp-wise, terylene warp knitting cloth is obtained and covers top bar；
