The production method of the expanded untwisted yarn towel of hollow
Technical field
The present invention relates to a kind of production method of daily towel, specifically be meant a kind of production method of untwisted yarn towel.
Background technology
, water imbibition comfortable in sense well is the primary requirement of consumer to towel products, also just because of this, untwisted yarn towel occupies increasing share on towel market, the mode of production of traditional untwisted yarn towel is to incorporate a PVA yarn into to satisfy the needs of weaving process with the brute force that strengthens non-twist yarn in spinning process, and in post processing the PVA yarn is removed fully and obtained that the looped pile effect is fluffy, the untwisted yarn towel product of comfortable feel.But traditional untwisted yarn towel is soft not enough more, feel is better not enough, the fluffy effect of looped pile is better not enough, skin-friendly can be better not enough.
Summary of the invention
The technical problem to be solved in the present invention is, allows untwisted yarn towel is soft more, feel is better, the fluffy effect of looped pile is better, skin-friendly can better untwisted yarn towel.
For achieving the above object, the invention provides the production method of the expanded untwisted yarn towel of a kind of hollow, comprise spinning, sizing, weave, the fabric post processor, in the spinning program,, obtain handling with PVA yarn double twisting plying after the yarn PVA and cotton fiber blending.
In the spinning program, described cotton fiber and PVA were according to 8: 2~9.5: 0.5 ratio blending.
In the spinning program, described cotton fiber and PVA were according to 9: 1 ratio blending.
In the spinning program, cotton fiber and PVA blending obtain handling with the PVA yarn double twisting plying of a 50~70s after the yarn.
In the spinning program, cotton fiber and PVA blending obtain handling with the PVA yarn double twisting plying of a 60s after the yarn.
In the sizing program, the rate of sizing of described sizing is 40~50%, the slurry that working concentration is bigger.
It is characterized in that: weave in the program, the fell plate height is set between the 3-3.5mm, and opening angle is controlled in the 24-28 degree scope, and the tension force of hair warp and ground warp yarn is about 45~55kgf, and the speed of a motor vehicle is 350-400 rev/min.
Weave in the program, the fell plate height is set between the 3-3.5mm, and opening angle is controlled in the 24-28 degree scope, and the tension force of hair warp and ground warp yarn is about 45~55kgf, and the speed of a motor vehicle is 350-400 rev/min.
In the fabric post processor, fabric put into 70~90 ℃ water and handle 25~35min.
In the fabric post processor, fabric put into 80 ℃ water and handle 30min.
Through the untwisted yarn towel that said procedure is produced, make the expanded effect of non-twist yarn strengthen, therefore more traditional untwisted yarn towel is soft more, feel is better, the fluffy effect of looped pile is better, skin-friendly can be better.
The specific embodiment
Further specify technical scheme of the present invention below by embodiment.
The production method of the expanded untwisted yarn towel of hollow of the present invention, its concrete steps are:
(1) spinning: in this process, set proper proportion PVA and cotton fiber are carried out blending, ratio can be set at 9: 1, obtain after the yarn after spin and handle the PVA yarn of incorporating a 60s once more into by double twisting in the link and be convenient to weave with the tension force that strengthens yarn.The ratio of PVA increases greatly in the yarn that obtains after like this spinning system being changed, therefore the fluffy better effects if of towel products looped pile that obtains.
(2) sizing: because this yarn belongs to the zero twisted yarn yarn, this yarn powerful relatively poor, this just need carry out the starching processing to yarn, and wherein the rate of sizing is about about 45%, and the concentration of increase slurry.
(3) weave: whole weaving process adopts known method to carry out, and in order to guarantee carrying out smoothly of weaving process, each technological parameter of loom is set, and considers the influence of the dynamics of beating up, and the fell plate height is set between the 3-3.5mm; Opening angle is controlled at the efficient that has guaranteed loom in the 24-28 degree scope; Suitably reduce the tension force of hair warp and ground warp yarn, be designed to about 50kgf.Suitably reduce the speed of a motor vehicle, be designed to 350-400 rev/min.
(4) post processing: fabric is carried out post processing, at first under 80 ℃ of hot conditions, PVA is removed, because the ratio of PVA is higher in this yarn, processing time in this process rises to 30min by the 20min in the conventional process mode and obtains slap-up removal to guarantee the PVA in the yarn, and removed various impurity such as the wax in the yarn, cotton seed hulls simultaneously, can carry out the bleaching and dyeing processing procedure after finishing dealing with.
Through the untwisted yarn towel that said procedure is produced, make the expanded effect of non-twist yarn strengthen, therefore more traditional untwisted yarn towel is soft more, feel is better, the fluffy effect of looped pile is better, skin-friendly can be better.
Though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; under the individual situation that deviates from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes according to the present invention, but these corresponding changes all should belong to the protection domain of the appended claim of the present invention.
