Description

Low-gram-weight suspension fabric

Technical Field

The utility model belongs to the technical field of spinning, and relates to a low-gram-weight suspension fabric woven by novel structural yarns.

Background

Since the 90 s of the 20 th century, the heavy silk fabric is popular with consumers due to elegant appearance, soft luster and comfortable wearing comfort. The heavy silk fabric takes natural silk fiber as a raw material, the silk consumption is twice of that of the common silk fabric, and the heavy silk fabric has the characteristics of no shrinkage, stiffness, easiness in finishing and the like, but the ready-made clothes are high in price and easy to wrinkle.

Nowadays, heavy cotton fabrics produced by replacing real silk fibers with cotton fibers appear on the market, and the square meter gram weight of the heavy cotton fabrics is 220g/m through various process treatments²In order to ensure the characteristics of difficult deformation of ready-made clothes and the like, the selected fibers are generally thicker and are commonly used for manufacturing clothes such as sweaters and the like, and a small part of the fibers are used for manufacturing T-shirts, but the concept of heavy pure cotton is not widely recognized due to the reasons of rough fabric, poor air permeability, more sweating, smell emission and the like.

Some researchers develop the fabric, for example, patent CN 212289081U discloses a non-deformable draping rib knitting fabric, which includes a fabric base layer and a surface layer, and prevents the fabric from deforming by using weft yarns, polyester linen yarns, elastic yarns, cotton yarns, spandex yarns and the like to increase the surface layer elasticity; some innovations are carried out on the processes of polyester composite yarn compounding technology, polyester/spandex covered yarn technology, surface elastic fabric weaving technology, after finishing and the like, and the draping acetic acid-like four-side elastic fabric is woven, but the process is complex.

Therefore, the research on the fabric which is easy to process, has the style similar to that of heavy silk, is fine and soft in hand feeling, has rich elasticity, drapability and smoothness, is bright in color, has good air permeability, is anti-fouling, quick-drying and is lighter and thinner has very important significance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art and provides the fabric which is similar to the style of heavy silk, fine and soft in hand feeling, rich in elasticity, drapability and smoothness, gorgeous in color, good in air permeability, anti-fouling, quick-drying, lighter and thinner.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:

a low gram weight suspension fabric is composed of warp yarns and weft yarns; the warp yarns are core-spun yarns; the weft yarn is a Solona filament yarn; the Solona filament is selected as the weft yarn, on one hand, the cross section of the Solona filament is in a special-shaped irregular state, after the fabric woven by the Solona filament is subjected to post-treatment, the gaps among filament fibers can be enlarged, the freedom degree of the movement of the fabric is increased, and the Solona filament fabric is endowed with drapability and fluffy feeling; on the other hand, because the draping coefficient and the fabric weft bending rigidity have obvious positive correlation, the detected sodana filament yarn as weft yarn has small bending rigidity, certain elongation at break and breaking strength and large activating ratio, so that the fabric has small draping coefficient, is easy to bend and has excellent draping performance, and the internal characteristic can strengthen the texture draping of the fabric in appearance and increase the overall dynamic draping performance of the fabric; in addition, the internal molecular structure of the Solona is like a spring, so that the Solona is soft and fluffy, and has excellent crease resistance, which is incomparable with the heavy silk fabric;

the core-spun yarn has a staple fiber-staple fiber cross section layered structure, the surface layer is roving, the core layer is slub yarn, the twist coefficient of the surface layer is 200-300, and the twist coefficient of the core layer is 0; the slub yarn is thin and thick along the length direction and is formed by alternately connecting thick sections and thin sections, the length of each thin section is 50-100 mm, the length of each thick section is 30-50 mm, and the thickness of each thick section is 1.3-1.8 times that of each thin section;

the preparation method of the slub yarn is prior art, the apparatus makes the front roller change the speed or pause on the spinning frame of the ring spinning, thus change the normal draft multiple, for example while spinning the base yarn, the clutch actuation keeps the front roller to operate normally, make the clutch lose the electricity, the front roller stops rotating, and the middle and back rollers are still in operation, pile up the fiber sent out between middle roller and front roller, when the clutch actuates the electricity again, the front roller begins to operate and take away the fiber piled up, will form the slub on the base yarn, or adjust the speed of the front roller fast, slow and not stop rotating and can realize the slub too, change the middle roller in addition, make the middle roller overfeed, can change the draft multiple too and produce the slub;

the preparation process of the core-spun yarn comprises the following steps: the method comprises the steps that a untwisting-twisting method is adopted, a core-spun ring spinning frame with a core-spun function is used, a roving is fed into a drafting zone of the core-spun ring spinning frame to serve as an outer wrapping fiber, slub yarn serves as core yarn, the twist direction of the core-spun ring spinning frame is opposite to that of the core yarn, the twist coefficient is 200-300, the quantitative ratio of the feeding amount (the fiber amount forming surface layer yarn) of the base yarn and the roving of the core yarn is 0.11-0.16, and the core-layer untwisted core-spun yarn with a layered structure is obtained through spinning, wherein fibers forming the core layer yarn and fibers forming the surface layer yarn are short fibers;

the core-spun yarn is spun by taking S-twisted slub yarn as core yarn and simultaneously drafting and twisting rough yarn as the surface layer of the core-spun yarn, and the yarn twisting direction of the core-spun yarn is Z twisting in the spinning process; in the preparation process of the core-spun yarn, firstly, the slub yarn is prepared as a core layer, S twisting is added, then core-spun is carried out, the S twisting of the slub yarn after core-spun is untwisted into untwisted yarn, so that the core yarn of the core-spun yarn is finally in a fiber state, and the drapability of warp yarn in a fabric can be increased in the initial slub shape in the untwisting process; the influence of the spinning process on the shape and structure of the core-spun yarn is specifically as follows:

(a) the utility model adopts the ring spinning technology, the surface layer roving is drawn and twisted and then is coated on the surface of the S-twist bunchy yarn of the core layer, and the core-spun yarn finally presents the twist direction which is the opposite direction of the core layer yarn, namely Z twist, in the coating process, the S-twist bunchy yarn of the core layer starts to be gradually untwisted due to the acting force of the opposite twist direction, in the untwisting process, the bunchy yarn not only moves at a certain linear speed, but also circularly rotates at a certain speed, and the composite motion of the linear operation and the circular motion enables the fiber in the yarn to generate a random orientation structure; the arrangement state of the fibers in the yarn is complex and has great randomness; the two sections of the slub sliver rotate relatively by the early-stage twisting, and the original fiber parallel to the yarn shaft in the sliver is inclined into a spiral line; in the core-spun process, the surface layer and the core layer are two relatively independent bodies, the surface layer fiber bundles are tightly gathered together under the action of tension and centripetal force, and short fibers are difficult to enter the surface layer area by virtue of spinning tension in a twisting triangular area; therefore, in the ring spinning core-spun composite yarn with the staple fibers wrapped by the staple fibers, the internal and external transfer degree is small, and the diameters of all parts of the fiber spiral line are unchanged when the internal and external transfer does not occur; therefore, theoretically, the arrangement state of the fibers in the yarn is assumed to be a cylindrical spiral line, so that the fibers in the yarn show random reverse spiral directional distribution movement in the untwisting process, and finally, the parallel straightening state along the longitudinal direction of the yarn is realized;

(b) the slub yarn of sandwich layer presents the outward appearance of neglecting thick neglected fine, when the effort that the yarn received is opposite rather than relative direction of motion, the frictional force that the roving of cortex and the slub yarn of sandwich layer produced can direct action on the surface fiber of slub yarn, the unsmooth fibre in slub yarn surface can receive the frictional force influence of different degree, lead to in the yarn relative slip between the fibre of free state and the fibre to increase, the loose degree increase in space between fibre and the fibre, fibrous dispersibility and the fibrous performance of cortex further combine in the sandwich layer yarn, make the warp reflect the anomalous fluffiness and the sense of dangling that similar silk has in appearance morphology, the concrete performance is: the longitudinal surface of the warp is smooth, the thickness is uniform, the thickness is changed in a few places, the luster is strong and not dazzling (similar to the pearlescence of silk), the touch is smooth and greasy, and the texture is long-lasting;

the low-gram-weight suspension fabric has the warp yarn number of 50-60, the weft yarn number of 40-50, the warp yarn density of 400-450/10 cm, the weft yarn density of 260-300/10 cm, the total tightness of 75% and the gram weight per square meter of 130-150 g/m²。
