Description

Technical Field

[0001] The utility model relates to the technical field related to household textiles and baby products, in particular to a four-layer high-elasticity twistless yarn summer baby blanket. Background Art

[0002] Baby blankets, which are considerate textiles designed specifically for infants and young children, have unique warmth retention, comfort, and soothing effects. It is not only a simple textile product but also a bridge connecting parent-child emotions, providing a warm and safe growth environment for the baby. Traditional baby blankets are particularly particular about material selection, mostly using natural fibers such as pure cotton or bamboo cotton as fabric materials. Pure cotton materials are famous for their excellent breathability, moisture absorption, and softness, which can effectively regulate the baby's body temperature, avoid overheating or overcooling, and at the same time reduce skin friction to protect the baby's delicate skin from harm. Bamboo cotton materials combine the natural antibacterial property of bamboo and the soft and skin-friendly characteristics of cotton, bringing a fresher and healthier sleep environment for the baby. The design of baby blankets fully considers the growth characteristics and actual needs of the baby. Its upper and lower surfaces use plain cloth fabrics, which not only ensure a good touch but also facilitate cleaning and maintenance. The middle interlayer is filled with fluffy and soft cotton wadding or other environmentally friendly wadding materials such as silk and down, giving the baby the most comfortable wrapping feeling. The functions of baby blankets are as follows: 1. Warmth retention function: In cold seasons or air-conditioned rooms, baby blankets can effectively lock in heat, providing a warm embrace for the baby and preventing colds and other diseases caused by cold; 2. Soothing effect: After the baby is born, it often feels uneasy and anxious when facing a strange environment. The soft touch and familiar smell of the baby blanket can simulate the feeling of the mother's embrace, giving the baby psychological comfort and a sense of security, helping to relieve separation anxiety and promote emotional stability; 3. Promote sleep: The wrapping feeling of the blanket can help the baby adapt to the external environment faster, reduce the startle reflex, and improve the sleep quality. Good sleep is an important guarantee for the healthy growth of the baby, and the baby blanket is exactly a great helper in this process; 4. Multifunctional use: As the baby grows, the uses of the baby blanket will gradually expand. It can not only be used as a baby blanket but also as a small cover blanket, bath towel, nap blanket, etc., meeting the baby's needs in different scenarios. This multifunctionality makes the baby blanket an essential practical good for family parenting.

[0020] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0021] Embodiment: As Figures 1-3 shown, the four - layer highly elastic untwisted yarn baby blanket for summer of the present invention includes an upper wrinkled layer 1, a first elastic interlayer 2, a second elastic interlayer 3, and a lower wrinkled layer 4 arranged in sequence from outside to inside. The upper wrinkled layer 1, the first elastic interlayer 2, the second elastic interlayer 3, and the lower wrinkled layer 4 are integrally woven by a composite four - layer plain weave; the first elastic interlayer 2 and the second elastic interlayer 3 drive the upper wrinkled layer 1 and the lower wrinkled layer 4 to form a wrinkled flower structure after water washing and shrinkage and rebound; both the upper wrinkled layer 1 and the lower wrinkled layer 4 are high - count untwisted yarn layers. Using high - count untwisted yarn as the surface material and matching it with a sparse four - layer fabric structure makes it have a cotton - like touch when contacting the skin, extremely soft and skin - friendly. Among them, the first elastic interlayer 2 and the second elastic interlayer 3 can elastically expand and contract, causing the upper wrinkled layer 1 and the lower wrinkled layer 4 to shrink and form, enabling the fabric to have a four - way stretch function and the size to be adjustable.

[0022] The density of the first elastic interlayer 2 and the second elastic interlayer 3 is 50% of the density of the upper wrinkled layer 1 and the lower wrinkled layer 4 in the above table. Compared with the ordinary interlayer filler structure of children's blankets, it has stronger air permeability and feels cool and comfortable when contacting the skin of children.

[0023] The upper wrinkled layer 1 is connected to the first elastic interlayer 2 through the first elastic connecting warp 5; the first elastic interlayer 2 is connected to the second elastic interlayer 3 through the second elastic connecting warp 6. The second elastic interlayer 3 is connected to the lower wrinkled layer 4 through the third elastic connecting warp 7. The first elastic interlayer 2 and the second elastic interlayer 3 are woven from pure cotton ply yarn and elastic yarn.

[0024] The manufacturing process of the present application is introduced herein. Specifically, the four-layer high-elasticity twistless yarn summer children's blanket is woven on a 280-type rapier dobby loom, and its trial production process flow is: process design - tissue design - yarn selection - yarn dyeing - warping - dobby program design - heddle drawing, reed threading - machine debugging - sample weaving - grey cloth dyeing - cutting - four-side edge binding and sewing - inspection and packaging.

[0025] Process design: Since the present utility model belongs to a multi-layer structure fabric and is mainly used as an infant blanket, the fabric softness, skin-friendly, non-irritating, warm, breathable and other health care functions should be fully considered in the process design. The warp and weft densities of the product should be selected appropriately. Considering the above factors, a 40-inch reed in the English system is used, with 3 warp threads inserted into each reed tooth. The warp density is: 236 threads / 10 cm, the English weft density is 60 threads / inch, and the weft density is: 236 threads / 10 cm. The finished product specifications are 80 cm in length, 80 cm in width, and the finished product weight is 260 grams per piece.

[0026] Tissue design: In order to ensure the softness and air permeability of the fabric, the fabric tissue is woven integrally with a composite 4-layer plain weave. The density of the middle two layers is 50% of the surface layer, increasing the air permeability while maintaining the fabric strength.

[0027] Yarn selection: As a blanket for infants, comfort is a common requirement. Since the skin of infants is particularly delicate and sensitive, slightly stiff textiles will cause irritation to the skin. Therefore, the selection of yarn for the upper and lower surface layers is particularly important. The weft yarn for the surface layer is 40S twistless yarn. The ultra-long cotton fibers and the ultra-low twist after treatment make the upper and lower surface layers as soft as cotton and have good skin-friendly properties. The second and third layers of the fabric use 40S / 2 pure cotton low-twist ply yarn. The loose tissue structure and the fluffy and soft yarn increase the air permeability of the fabric. Some warp and weft yarns in the middle layer are 40S / 2-70D spandex-covered yarn, making the fabric have four-way elasticity. The contraction of the middle layer drives the upper and lower surface layers to form a wrinkled effect.

[0028] Warping: This fabric belongs to a 4-layer variable plain fabric. Since the middle layer has a certain elasticity, after shrinkage through water washing treatment, it pulls the upper and lower surface layers to form a fabric structure with four-way elasticity. According to the arrangement requirements of the four layers of warp yarns, excluding the selvedges, the arrangement cycle of the middle pattern part is: 37 pieces of 40S / 2 pure cotton raw yarn + 1 piece of 40S / 2-70D elastic yarn + 8 pieces of 40S / 2 pure cotton raw yarn + 1 piece of 40S / 2-70D elastic yarn + 25 pieces of 40S / 2 pure cotton raw yarn. Fix the reed and the dividing reed according to the density designed in the process. The total number of warp yarns is 5964, the yarn arrangement density is 275 pieces / 10 cm, the width of the beam is 217 cm, and the warping beam is prepared for weaving on the loom.

[0029] Dobby program production: Select to weave on a 280-type dobby rapier loom according to the width of the loom. Use the 280-type dobby CAD design software to fill the fabric texture into the texture table and design the number of weft yarns in the cycle. The software automatically generates a program in dobby format and copies it to the electric control cabinet of the machine for waiting to be used on the loom.

[0030] Drawing the heddles and threading the reed: When drawing the heddles on a 280-type dobby rapier loom, divide it into 4 zones from front to back. The frontmost zone is the upper surface layer zone, followed by the second layer zone, the third layer zone, and the lower surface layer zone. The threading order is: first thread 1 piece of wire through the heddles of the upper surface layer zone, then thread 1 piece of wire through the heddles of the lower surface layer zone, and thread 1 piece of wire through the heddles of the second layer of the interlayer; thread 1 piece of wire through the heddles of the upper surface layer, then thread 1 piece of wire through the heddles of the lower surface layer, and thread 1 piece of wire through the heddles of the third layer of the interlayer. Draw the entire warp yarn according to the above cycle. Every 3 pieces of wire enter one reed tooth. A total of 946 reed teeth are threaded in the middle pattern part of each piece. Repeat the above operation to draw 2 widths to complete the work of drawing the heddles and threading the reed, and wait for debugging on the loom. The upper surface layer zone, the second layer zone, the third layer zone, and the lower surface layer zone mentioned above refer to the upper surface wrinkled layer 1, the first elastic interlayer 2, the second elastic interlayer 3, and the lower surface wrinkled layer 4 in this application in turn.

[0031] Debugging on the loom: Copy the designed dobby program to the electric control system of the machine. Thread the weft yarns of 40S twistless yarn, 40S / 2-70D elastic ply yarn, and 21S raw yarn into the corresponding weft storage devices respectively. Adjust the weft density of the machine to 60 pieces per inch. Jog the machine to check the dobby heddle lifting rule. The body part of the fabric adopts a 4-layer variable plain texture. In one texture cycle, the number of weft yarns is 12 and the number of warp yarns is 12. The texture table is shown in the appendix Figure 3, check whether the lifting law of the point - moving machine compared with the heddle frame is the same as that set in the weave table, and check whether the beating - up situation conforms to the design. The beating - up order is as follows: The first weft of 40S non - twisted yarn is the upper surface layer weft, and the warp is lifted singly; the second weft of 40S non - twisted yarn is the lower surface layer weft, and the warp is lifted singly; the third weft of 21S raw yarn is the second - layer weft, and the warp is lifted singly; the fourth weft of 40S non - twisted yarn is the upper surface layer weft, and the warp is lifted doubly; the fifth weft of 40S non - twisted yarn is the lower surface layer weft, and the warp is lifted doubly; the sixth weft of 21S raw yarn is the third - layer weft, and the warp is lifted singly; the seventh weft of 40S non - twisted yarn is the upper surface layer weft, and the warp is lifted singly; the eighth weft of 40S non - twisted yarn is the lower surface layer weft, and the warp is lifted singly; the ninth weft of 21S raw yarn is the second - layer weft, and the warp is lifted doubly; the tenth weft of 40S non - twisted yarn is the upper surface layer weft, and the warp is lifted doubly; the eleventh weft of 40S non - twisted yarn is the lower surface layer weft, and the warp is lifted doubly; the twelfth weft of 21S raw yarn is the third - layer weft, and the warp is lifted doubly. The order of the binding warp is that the first - layer binding warp binds the second layer, the second - layer binding warp binds the third layer, the fourth - layer binding warp binds the third layer, and the binding warp in the middle interlayer is formed by the interweaving of 40S / 2 - 70D elastic yarn and 40S / 2 - 70D elastic weft in the interlayer to form an interlayer elastic layer. After the lifting law is correct, debug the machine to ensure that there are no defects on the towel surface, and then weave the next sample. After comparing with the process sheet and confirming that the specifications, weight, pattern match the design, the machine debugging is completed.

[0032] Sample weaving: Adjust the towel surface quality according to the process requirements, without defects such as incorrect threading, reed, uneven density, and skipped stitches, the weave law conforms to the design, and the weft is used correctly. After taking off the loom, measure the off - loom specifications and weight of the grey cloth. If they meet the process requirements, the sample can be woven.

[0033] Grey towel water treatment: In order to break the twist of the non - twisted yarn on the fabric surface, increase the soft and skin - friendly performance of the fabric, and remove the excess impurities on the yarn surface, it is necessary to carry out water treatment on the off - loom grey towel. During the water treatment process, chemical auxiliaries such as fluorescent agents that are irritating to children's skin cannot be added. Ensure that the basic safety and technical performance indicators of the treated fabric can meet the relevant requirements of GB 31701 "Safety Technical Code for Textile Products for Infants and Children". Use shaping and drying to make the fabric specifications stable and keep the upper and lower surface wrinkles uniform and beautiful.

[0034] Cutting and sewing: This product is woven in continuous lengths and undergoes water treatment. After drying, it needs to be longitudinally and horizontally cut first, and then the four - week edge - binding sewing is carried out. The selection of the edge - binding cloth should also meet the relevant requirements of the national mandatory standard GB 31701 "Safety Technical Code for Textile Products for Infants and Children" and be coordinated with the main color of the product. The edge - binding width is 3 cm, and the sewing stitch density is 16 stitches / 5 cm, meeting the national standard requirements, and there should be no phenomenon of loose corners or open seams.

[0035] Inspection and packaging: Trim the thread ends of the sewn product neatly, grade it according to the customer's standards or national standards, and pack the finished product according to the packaging process requirements.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
