Description

Low shrinkage webbing and method of making same

Technical Field

The invention relates to the technical field of textiles, in particular to a low-shrinkage woven belt and a manufacturing method thereof.

Background

The woven belt is a narrow fabric or tubular fabric made of various yarns as raw materials, is a common accessory on clothes, such as a collar, a corner fork, a front barrel and the like used for the clothes, and is usually sewn with a fabric. The shrinkage rate of the cotton shuttle weaving belt is generally larger and is basically more than 10%. However, excessive shrinkage of the webbing tends to cause wrinkling of the garment, affecting the appearance and size of the garment. At present, the cotton shuttle woven belt can be sewn with the fabric after being pre-shrunk, the existing pre-shrinking method mainly comprises steam ironing and water soaking drying, wherein the water soaking drying is good for pre-shrinking the cotton shuttle woven belt, the shrinkage rate of the cotton shuttle woven belt can be reduced to 4% -7% through multiple water soaking drying, but the pre-shrinking needs heat energy or water, the energy consumption is high, and the flow is long. The industrial standard usually requires that the shrinkage rate of the woven belt is within 5 percent, so that the shrinkage rate of the woven belt with a loose part structure can not reach the industrial standard, and even if the shrinkage rate standard is occasionally reached by sampling inspection, the shrinkage rates of different positions of the sampling inspection are extremely unstable in different production batches of the woven belt.

In order to avoid the adverse factor of large shrinkage rate of the cotton woven belt, the cotton woven belt is usually replaced by a polyester filament woven belt, a polyester staple fiber woven belt or a cotton-polyester blended woven belt, but all of the cotton woven belt and the polyester staple fiber woven belt have other problems. Although the shrinkage rate of the polyester shuttle weaving belt can be controlled within 5%, the polyester filament weaving belt has the problems of soft hand feeling, inconsistent style and ready-made clothes style, poor water absorption, easy generation of static electricity, poor wearing experience and the like. Although the appearance of the polyester staple fiber woven tape is similar to that of a cotton shuttle woven tape, the polyester staple fiber woven tape is poor in water absorption and prone to pilling. Although the cotton-polyester blended fabric tape can reduce the characteristics of easy fluffing and pilling and poor water absorption of the polyester staple fiber fabric tape, the cotton and polyester dyeing conditions and dyes are different, so that the cotton and polyester dyeing and dyeing are required to be respectively carried out, the production process is long, the energy consumption is high, and the resource consumption is large.

Specifically, the weft yarn 120 is a natural fiber yarn, a synthetic fiber yarn, or a mixed yarn of natural fibers and synthetic fibers

Shrinkage of a fabric refers to the percentage of fabric shrinkage after the fabric has been washed or soaked in water. High and low shrinkage yarns refer to the relative magnitude of the shrinkage of the woven fabric from such yarns.

In this way, a small amount of first yarns 113 with low shrinkage are mixed in the warp yarns 110 of the woven tape 100, and the radial internal stress of the weft yarns 120 with high shrinkage can be quickly reduced through the first yarns 113 with low shrinkage, so that the overall shrinkage of the woven tape 100 is reduced, the shrinkage of the woven tape is less than or equal to 4%, and the shrinkage is stable. Moreover, the weft yarns 120 and the second yarns 111 which are main components of the woven belt 100 are yarns made of one or more of natural fibers and artificial fibers, so that the woven belt 100 has soft hand feeling and good air permeability and moisture absorption, has the style of natural raw material fabrics, and can well meet the requirements of ready-made clothes on the wearability of the woven belt.

Further, the second yarn and the weft yarn are each selected from yarns of one or more components of cotton yarn, rayon yarn, and cotton-viscose blended yarn.

Specifically, the second yarn and the weft yarn may be a primary-color embryonic yarn or a colored yarn, respectively, and when the weft yarn and the second yarn are the primary-color embryonic yarns, a dyeing process is required in the subsequent step, and when the weft yarn and the second yarn are the colored yarns, the dyeing process is not required in the subsequent step.

Furthermore, the tex of the second yarn is 19tex to 120tex, and the tex of the weft yarn is 19tex to 60 tex.

Further, the first yarn accounts for 1% -7% of the total weight of the warp and weft during weaving.

It can be understood that, in order to ensure the low shrinkage rate of the woven tape and maintain the characteristics of the yarns with high shrinkage rate, the amount of the yarns with low shrinkage rate needs to be controlled within the range of 1 wt% to 7 wt%. It is also worth noting that as the number of features of the high shrinkage yarn increases, the number of features of the low shrinkage yarn also increases, and the amount of usage increases accordingly.

Step two, weaving: and weaving or tatting the warp yarns and the weft yarns, and uniformly weaving the first yarns into the woven belt to obtain the woven belt.

Specifically, the first yarn is woven into the webbing in the following manner: the yarn is independently used as warp yarn to be woven, the first yarn and the second yarn are twisted and then woven, the first yarn and the second yarn are woven in a doubling mode, the second yarn is wrapped by the first yarn to form wrapping yarn to be woven in, or the second yarn is wrapped by the first yarn and then is twisted and woven in with the second yarn.

Specifically, the blending mode comprises the following steps: the first yarn and the second yarn are twisted, the first yarn is covered by the second yarn to form a covering yarn, or the covering yarn is formed and then twisted with part of the second yarn to form a double-ply yarn.

In an embodiment, the method further comprises a pre-shrinking step.

Specifically, the woven belt freely passes through a rubber blanket type preshrinking machine under the tension state of the self gravity, the preshrinking temperature is 100 ℃, the preshrinking time is 5 yards/minute, and the preshrinking pressure is 4 KPa.

In one embodiment, the method further comprises a step of dyeing before preshrinking.

It will be appreciated that when the weft and second yarns are dyed yarns, the dyeing step may not be performed. When the weft and second yarns are primary-colored embryonic yarns, the webbing may be colored by dyeing.
