Hemming-stitch-free warp-knitted elastic fabric and method for knitting thereof
The present invention discloses a hemming-stitch-free warp-knitted elastic fabric and a method for knitting thereof. The method includes: making a non-elastic yarn pass across a guide needle of the first guide bar and form the surface of the fabric by knitting via two needles or three needles in a 1×1 or 2×1 warp plain stitch loop mode, and making an elastic yarn pass across a guide needle of the second guide bar and form the inside of the fabric by knitting with the aforementioned non-elastic yarn in the same direction via three needles in a open double warp plain stitch loop mode, and two loops are continuously formed on each course of the open double warp plain stitch loop. The hemming-stitch-free warp-knitted fabric produced according to the present invention has good snagging grade, moderate horizontal straight tensile force and good resilience.
COMPRESSION AND/OR CONTENTION GARMENT FOR LYMPHOEDEMA TREATMENT
Disclosed is a compression and/or contention garment for lymphoedema treatment, the garment including a main body made of a compression textile. The garment has at least a first targeted area, in which the garment includes at least one layer of reinforcement textile, and at least a second targeted area, in which the garment includes at least one layer of contention textile.
BIO-BASED SYNTHETIC FABRICS AND PREPARATION METHODS THEREOF
The present disclosure provides a fabric, a preparation method thereof and clothing formed therefrom. The preparation method includes the following steps: obtaining bio-based synthetic fiber chips from textile waste materials; obtaining extruded filaments from the bio-based synthetic fiber chips by adopting a spinning solution; and weaving and interlocking the extruded filaments with bio-based elastic fibers to obtain the fabric. The prepared fabric is obtained from the textile waste materials, so that waste recycling is realized, and the pollution of the textile wastes to the environment is avoided. The spinning solution is adopted in the preparation process of the fabric, so that the opacity and hydrophilicity of the fabric can be enhanced.
FABRIC AND ARTICLES HAVING FIRE-RESISTANCE, CUT-RESISTANCE, AND ELASTIC RECOVERY AND PROCESSES FOR MAKING SAME
A flame-resistant cut-resistant fabric, and a glove or other article comprising the fabric, the fabric comprising: (a) at least one first yarn comprising at least 50 weight percent heat-resistant polymeric fiber, wherein at least 30 weight percent of the polymeric fiber present in the at least one first yarn is cut-resistant heat-resistant polymeric fiber having a cut resistance of 500 grams force or higher per ASTM F2992-15; and (b) at least one second yarn having a sheath/core construction with a sheath of halogenated self-extinguishing staple fibers and a core comprising at least one continuous elastomeric filament, wherein 60 to 95 weight percent of the at least one second yarn is halogenated self-extinguishing fiber, and the halogenated self-extinguishing fiber is in contact with the at least one continuous elastomeric filament, the second yarn being free or substantially free of inorganic fibers; the fabric having a maximum after-flame time of two seconds or less and weight loss of 5 weight percent of less when tested per NFPA-2112-2018.
Polyurethane urea elastic yarn having improved dyeability and manufacturing method therefor
The present invention relates to a polyurethane urea elastic yarn having improved dyeability and a manufacturing method therefor. Through a process of forming a prepolymer by mixing polyethyleneglycol with polyol and then adding diisocyanate to the same in a prepolymer manufacturing step during the manufacture of a polyurethane urea elastic yarn, the hydrophilicity of the polyurethane urea elastic yarn is improved such that the accessibility of an acid dye is enhanced, thereby enabling the dyeability of the polyurethane urea elastic yarn to be enhanced and an advantage of dye color deepening of a fabric, in which nylon and a polyurethane urea elastic yarn are knitted together, to be expected.
ARBITRARILY-CUT LACE FABRIC OF NON-HOT-MELT MATERIAL
Arbitrarily-cut lace fabric of non-hot-melt material includes a fabric body knitted on a lace machine. The fabric body has a main body knitted by using two filament bars and two spandex bars. A pattern layer, formed by knitting an elastic yarn or filament following a weft insertion structure or a looping structure using a pattern bar, is provided on the main body, and an elastic weft opening layer, a warp opening layer and a tight resistance layer are further provided inside the main body. The present invention has the advantages of good tensile properties in the warp and weft directions, which can be stretched freely in all directions and is not prone to falling apart after being cut, and can be widely used in underwear, corsets. sports, and leisure clothing.
Non-chemical, mosquito bite-resistant garments
An insect-proof, form-fitting undergarment is provided having top and bottom parts formed of selected breathable materials and having omnidirectional stretch properties, and which top and bottom parts may be securely joined at the waist to prevent insect entry. A superfine knitted fabric is utilized to prevent insect bites.
Protective textile with tungsten and manufacturing method thereof
In one aspect, a method of manufacturing a protective textile may include steps of (a) twisting a first yarn with a tungsten filament; and (b) using a second yarn to cover the yarn-tungsten product generated in step (a). The yarn generated in step (b) is further twisted with an elastic spandex. In one embodiment, the first yarn is selected from a group of Nylon, Polyethylene Terephthalate (PET), cotton yarn, bamboo fiber and Tencel. In another embodiment, a Polyethylene (PE) fiber is the second yarn, and the third yarn may include Nylon, PET or PE. The protective textile is advantageous because it is light, thin, soft and highly cut resistant. Also, it has great electrical conductivity and chemical stability, and it is not easy to deform after washing.
TWISTED YARN, TWISTED YARN PRODUCTION DEVICE AND TWISTED YARN PRODUCTION PROCESS
The invention discloses a twisted yarn, a twisted yarn production device and a twisted yarn production process. The twisted yarn is obtained from an air-covered yarn and a core-spun spandex yarn through doubling, twisting and winding. Compared with the prior art, the invention utilizes the feature that the air-covered yarn has rhythmic network points. After the air-covered yarn and the core-spun spandex yarn are made into a twisted yarn, the air-covered yarn can clamp the core-spun spandex yarn, thereby effectively preventing the retraction of the spandex in the core-spun spandex yarn.
