Embodiment 1

[0027] Such as figure 1 As shown, this embodiment provides a spandex Roman cloth with strong stretch recovery. The Roman cloth is interwoven with spandex and viscose. The brocade-wrapped spandex is covered on the front and back of the viscose respectively by the upper and lower needles of the circular machine.

[0028] Step 1: Raw material preparation: 70D / 24F (nylon) wrapped with 40D spandex filament, 30S viscose.

[0029] Step 2: Weaving on the machine: choose a machine number of 24G large circular machine to weave, adopt positive yarn feeding method, the coil length of brocade covered spandex is 15cm, the coil length of viscose is 12.5cm, and the weight of finished fabric is 320g / m 2 .

[0030] Step 3: Cut and roll on the machine to ensure the flatness of the cloth surface and avoid creases on the cloth surface.

[0031] Finishing process:

[0032] Step 4: Open-width water washing of the rough: open-width water washing is performed on the fabric after step 3 at a temper...

Abstract

The invention relates to polyurethane Roman cloth with high stretching resilience and a preparation method thereof. The Roman cloth is formed by interweaving nylon-coated polyurethane and mucilage glue; the mucilage glue is weaved on the front and back surfaces of a fabric in a cotton wool weaving way; and the nylon-coated polyurethane is used for covering the front and back surfaces of the mucilage glue respectively in an up-down knitting way of a circular knitting machine. The preparation method comprises the following steps: (1) weaving, namely obtaining blanks and performing fabric slitting, curling and finishing; and (2) performing after-finishing on finished fabrics, namely performing open width washing, pre-shaping, dyeing, mellow finishing, dewatering, drying and re-shaping to obtain the polyurethane Roman cloth. The polyurethane Roman cloth has the characteristics of soft hand feel, good elasticity, massiness, good heat retention property, high stretching resilience, fold resistance and the like; the problems of poor stretching resilience and non fold resistance of general Roman cloth are solved; and the practicality of the Roman cloth is improved.

Description

technical field [0001] The invention belongs to the field of roman cloth and its preparation, in particular to a spandex roman cloth with strong stretch recovery and a preparation method thereof. Background technique [0002] Knitted fabrics are made of loops connected in series, and can be divided into weft knitting and warp knitting according to the direction of the looping. Due to the large gap between the coils of the weft knitted fabric, the coils are easy to slip during the stretching process, which makes the knitted trousers easy to deform and difficult to recover during wearing, which greatly reduces the application of knitted fabrics in the field of trousers. . [0003] Roman cloth is a kind of double-sided knitted fabric, with four loops and one loop, the first two loops are cotton and wool knitting, the third loop is all loops, and the fourth loop is all loops. Spandex Roman cloth is fed with spandex during the weaving process. The fabric is soft, elastic, thick...
