Problems solved by technology

Nowadays, some pillowcases are reflected by customers after being filled with duck down or hollow staple fibers, and the pillowcases are distorted, which is very unsightly and affects sales, so it is required to improve the pillowcases
[0004] The existing technical solutions have very high requirements on the fabric, and weft skew and weft arc are not allowed. It is required to arrange the weft arc process and pre-shrinking process during fabric production to eliminate internal stress, resulting in a substantial increase in fabric cost and weakening product market competitiveness.
The pillowcase produced by the original technology is skewed after being filled with duck down or hollow staple fiber, and the original symmetrical square or rectangle becomes an asymmetrical parallelogram, which is very unsightly.

Embodiment 1

[0027] A pillowcase production process that is filled with duck down or hollow staple fibers without pinching, the process flow is as follows figure 1 , including the following steps:

[0028] Step 1: Spread the cloth. Use the conventional cloth spreading machine to spread the cloth by cutting and flipping the two-way cloth. Only two layers of fabrics are spread, and the cloth is spread in the same direction, which can ensure that the pieces formed by subsequent cutting can maintain the same direction. Adjust the tension of spreading to 80N, and adjust the speed of spreading to 60 m / min. Change the traditional spreading tension and speed to avoid wrinkles and unevenness of subsequent fabrics;

[0029] Step 2: Cutting. Lay a layer of fabric from the required length point back to the original point and then cut it. Turn the head of the spreading machine 180°, and then spread it back to the original point from the required length point to cut it. This way of spreading the fabric ...

Embodiment 2

[0034] A pillowcase production process that is filled with duck down or hollow staple fibers without pinching, the process flow is as follows figure 1 , including the following steps:

[0035] Step 1: Spread the cloth. Use the conventional cloth spreading machine to spread the cloth by cutting and flipping the two-way cloth. Only two layers of fabrics are spread, and the cloth is spread in the same direction, which can ensure that the pieces formed by subsequent cutting can maintain the same direction. Adjust the tension of spreading to 90N, and adjust the speed of spreading to 50 m / min. Change the traditional spreading tension and speed to avoid wrinkles and unevenness of subsequent fabrics;

[0036] Step 2: Cutting. Lay a layer of fabric from the required length point back to the original point and then cut it. Turn the head of the spreading machine 180°, and then spread it back to the original point from the required length point to cut it. This way of spreading the fabric ...

Embodiment 3

[0041] A pillowcase production process that is filled with duck down or hollow staple fibers without pinching, the process flow is as follows figure 1 , including the following steps:

[0042] Step 1: Spread the cloth. Use the conventional cloth spreading machine to spread the cloth by cutting and flipping the two-way cloth. Only two layers of fabrics are spread, and the cloth is spread in the same direction, which can ensure that the pieces formed by subsequent cutting can maintain the same direction. The tension of spreading is adjusted to 100N, and the speed of spreading is adjusted to 50 m / min, changing the traditional tension and speed of spreading to avoid wrinkles and unevenness of subsequent fabrics;

[0043]Step 2: Cutting. Lay a layer of fabric from the required length point back to the original point and then cut it. Turn the head of the spreading machine 180°, and then spread it back to the original point from the required length point to cut it. This way of spread...

Abstract

The invention discloses a process for producing a pillowcase not obliquely kneaded after being filled with duck down or hollow staples. The process includes the following steps of firstly, laying a fabric, wherein the fabric is laid through a conventional fabric laying machine by means of the cutting, turning and bidirectional fabric laying mode in the same direction; secondly, tailoring the fabric, wherein after the fabric is laid, the two ends of the fabric are tightly pressed, the fabric is tailored into cut-parts by scissors on the fabric laying machine, the radian and latitude of tailoring do not exceed 5%, the four corners of the tailored cut-parts are clamped by spring clips to be placed; thirdly, conducting sewing, wherein the edges of the upper layer and lower layer cut-parts clamped by the spring clips are sewn through a sewing device; fourthly, filling the pillowcase with the duck down or hollow staples after the pillowcase is sewn to prepare a pillow. The traditional fabriclaying mode is changed, the tension, speed and thickness of fabric laying are improved, the same pile of cut-parts are used during sewing, and therefore the sewn pillowcase cannot be obliquely kneaded and is quite symmetrical and attractive in appearance after being filled with the duck down or hollow staples.

Description

technical field [0001] The invention relates to a production method of a pillowcase, in particular to a production process of a pillowcase which is filled with duck down or hollow short fibers and does not pinch. Background technique [0002] Household textiles are also called decorative textiles, together with clothing textiles and industrial textiles, they constitute a third of the textile industry. As an important category of textiles, home textile products are called soft decoration in the matching of room decoration, and it plays a decisive role in the construction and transformation of the environment. It has come all the way from the traditional daily needs of covering up, covering up, and washing. Today's home textile industry has a multi-functional consumption style such as fashion, personality, and health care. The textile industry of home textiles In home decoration and space decoration, it is gradually becoming the new favorite in the market. The development hi...
