Have you ever thought that the carpet laid at home may also be an invisible killer. Human sweat, oil and dander remain on the carpet, and the gaps in the yarn are particularly suitable for the growth and mass reproduction of bacteria and mites. These bacteria and dust mites can make people suffer from malnutrition symptoms, cause skin allergies, and aggravate diseases such as asthma. Human health. While experiencing the comfort of the carpet, the potential hazards of bacteria and mites should al

Yarn is divided into: ①Short fiber yarn, which is made of short fiber (natural staple fiber or chemical fiber cut fiber) by spinning, and is divided into ring-spun yarn, free-end spinning, self-twisting yarn, etc. ②Continuous filaments, such as natural silk and chemical fiber filaments, with or without twisting, smooth filaments or textured filaments, etc. ③ Short fiber and continuous filament combined yarn, such as polyester-cotton filament core-spun yarn, etc. The thread is made of two or m

The reasons for uneven mercerization and mercerization of yarns are mainly as follows:①The mercerized yarn is unevenly scoured, impermeable, poorly degreased, not washed cleanly after scouring, uneven capillary effect, excessively long stacking time after scouring, and mercerizing in the order of scouring pots.② Before mercerizing, the yarn blanks have uneven water content, and are partially damp or dry. After dehydration, the yarn blanks are stacked for too long, and the surface is exposed to

How is sewing thread produced?Regarding the production process of sewing thread, there are two production processes of continuous long fiber and short fiber. Long-fiber sewing thread: 1. The continuous composite monofilament with F (hole) number is made by cutting, drawing, shaping and winding; 2. The composite monofilament is made of white strands made by primary twisting and double twisting. Thread embryo yarn; 3. After dyeing and finishing workshop for smooth dyeing; 4. Packing and winding to

Polyester low elastic yarn is a type of textured yarn of polyester chemical fiber. It is made of polyester chip (PET) as raw material, and polyester pre-oriented yarn (POY) is spun at high speed, and then processed by drafting and false twisting. It has the characteristics of short process, high efficiency and good quality. Polyester low elastic yarn has the characteristics of high breaking strength and elastic modulus of general polyester, excellent heat setting, good resilience, heat resistanc

Yarn is a continuous strip of textile fibers with certain mechanical properties, fineness and softness.The so-called yarn actually refers to the general term of yarn and thread, which is defined as follows in clothing material science: yarn is the arrangement of many short fibers or filaments in an approximately parallel state, and along the axial direction Rotate and twist to form a slender object with certain strength and linear density; and thread is a strand formed by twisting two or more si

1. According to the structure and shapeDivided into filament yarn, spun yarn, special yarn.(1) Filament yarn1. Monofilament: a single filament2. Multifilament: A tow composed of multiple filaments, which is further divided into untwisted multifilament and twisted multifilament.3. Composite twisted yarn: Twisted multifilament yarns are combined and twisted one or more times.4. Textured yarns: elastic or highly bulky yarns made of synthetic fibers that plasticize and deform when heated. For exampl

An antibacterial and flame retardant yarn and a production process thereof, the yarn comprises: a core layer and a surface layer covering the outer wall of the core layer, the core layer is formed by intertwisting an antibacterial strand and a flame retardant strand, and the surface layer comprises The antibacterial coating, the heat insulating fiber layer and the flame retardant coating are sequentially arranged on the surface of the core layer from the inside to the outside; the antibacterial

Different types of yarns have different properties and appearance styles to form fabrics. The basic characteristics of the yarn are the important characteristics and expressions of the yarn structure, which determine the appearance and internal quality of the yarn, and also affect the properties of the fabric.1. Cotton yarnAccording to the spinning system, it is divided into carded yarn, combed yarn and waste spinning.Carded yarnThe fibers are not arranged neatly, the evenness is not uniform, th

The antibacterial, heating, gentle and warm series of yarns developed and mass-produced by Liyuan Fiber can be used for knitted underwear, underwear, socks, sports and leisure clothing, home textiles (suit fabrics, soft seats), towels, denim clothing, etc. The successful development of this variety series has skillfully combined the two functions of heat preservation and antibacterial, which greatly improved the added value of the product and opened another door for the company's product mar
