Best Material For Children's Clothes

What is the best type of material for children's clothes?

When it comes to choosing the best material for children's clothes, there are a few factors to consider, such as comfort, durability, and ease of care. Here are some of the best materials to consider:

  1. Cotton: Cotton is a natural and breathable material that is gentle on a child's skin. It's also durable and easy to care for, as it can be machine washed and dried. Cotton is a great choice for everyday clothes, such as T-shirts, leggings, and pajamas.
  2. Bamboo: Bamboo is a soft and hypoallergenic material that is perfect for children with sensitive skin. It's also eco-friendly, as it's a renewable resource that grows quickly without the need for pesticides or fertilizers. Bamboo is often used for baby clothes, such as onesies and swaddles.
  3. Wool: Wool is a warm and insulating material that is great for cold weather. It's also soft and comfortable against the skin and has natural antibacterial properties. Wool is often used for sweaters, hats, and mittens.
  4. Linen: Linen is a lightweight and breathable material that is perfect for hot weather. It's also durable and easy to care for, as it can be machine washed and dried. Linen is often used for dresses and shirts.
  5. Synthetic blends: Synthetic blends, such as polyester and spandex, are often used in children's activewear, such as leggings and sports uniforms. They are durable and stretchy, which makes them perfect for active children.

Ultimately, the best material for children's clothes depends on the child's needs and the intended use of the garment. It's important to choose materials that are comfortable, safe, and easy to care for to ensure that children can enjoy their clothes while staying healthy and happy.

Care guide

Caution
[body]
This care sheet provides general information only for handling Carolina™ bacterial cultures. When you work with bacteria, it is imperative that you use sterile techniques at all times. Failing to use sterile techniques can contaminate cultures and work areas, and cause health and safety risks. See our Carolina™ Techniques for Studying Bacteria and Fungi Manual (item #154664) for descriptions of sterile techniques and standard practices for handling bacterial cultures.

Immediate care and handling
[body]
When your bacterial cultures arrive, immediately open the shipping container and remove the cultures. We ship cultures in tubes, plates, and as MicroKwik Culture® freeze-dried cells. Visually inspect each culture. Ensure that tubes are intact with caps securely in place, plates have no cracks and lids are secured by tape, and plastic bags containing MicroKwik Culture® cells are securely closed with the enclosed tube and vial intact.

You must seal any culture damaged during shipment—and anything it contaminated—in an autoclavable bag, and then sterilize it by autoclaving or soaking all contaminated materials in disinfectant. Note: Never discard a damaged, unsterilized culture in the trash. Know and follow your school or district’s guidelines for proper disposal. Contact our Customer Service at 800.334.5551 for a replacement of your damaged culture. It will help to have your order number available when you call.

Hold most cultures at room temperature, 20 to 22° C (68 to 73° F). For tube cultures, loosen the cap and keep the culture tube upright in a test tube rack or beaker. For best results, use cultures within 3 to 5 days of receipt; however, most bacterial cultures remain usable for up to 4 weeks when held at room temperature. Keep in mind that Carolina provides a variety of bacterial cultures and some have very specific care and handling needs that differ from these general guidelines. Vibrio fischeri, for example, must be kept in the dark and subcultured 2 to 3 times per week to maintain bioluminescence.

Maintaining and culturing
[body]
Eventually your bacterial culture will deplete the nutrients of the medium in or on which it is growing and will need subculturing. Before working with bacterial cultures, wash your hands with soap and water, ensure that the work area is draft free, and wipe the work surface with 70% alcohol or similar disinfectant. Note: Always check the culture for signs of contamination immediately prior to using. Never work in an area where food is prepared or consumed.

Transfer broth cultures to fresh broth using a sterile pipet or loop or streak onto agar using a sterile inoculating loop. For faster growth, you can incubate most cultures at 25 to 30° C (77 to 86° F). After making the transfers, clean the work area with disinfectant and wash your hands again. Either autoclave the old stock cultures and glassware, or cover them with disinfectant overnight. We recommend the use of Clavies® Autoclavable Bags (item #831642) for disposal.

Biosafety
[body]
In the US the CDC (Centers for Disease Control) sets standards for the safe handling of microorganisms according to their Biosafety Level (BSL). There are 4 Biosafety Levels with BSL-1 being the lowest risk microorganisms and BSL-4 being the highest risk. Bacterial cultures provided by Carolina Biological Supply Company fall into BSL-1 and BSL-2. Our catalog and online listings identify BSL-2 bacterial cultures as pathogens. They are only available as MicroKwik Culture® freeze-dried cells, and we can only ship them to colleges and universities. Cultures not identified in our listings as pathogens are BSL-1.

The CDC standards for working with BSL-1 microorganisms include the following:
[bulleted list]
Follow all standard microbiological practices.
Work can be performed on an open lab bench or table.
Wear personal protective equipment (PPE), i.e., lab coats, gloves, and eye protection, as needed.
A sink for hand washing.
Doors that separate the lab room from the rest of the facility.

For working with BLS-2 microorganisms the CDC recommends all of the above, plus the following:
[bulleted list]
Restricted access to the lab room while cultures are being used.
PPE to include face shields as needed.
All procedures that can produce a splash or an aerosol must be performed within a biological safety cabinet.
An autoclave or other method of decontamination for proper disposal.
Self-closing doors that separate the lab room from the rest of the facility.
An eyewash station.

FAQs
[body]
Which agar should I use for my bacterial cultures?
In Carolina’s print and online catalogs, the product descriptions for our bacterial cultures include the type of nutrient medium that we use for each culture. This information also appears on the label affixed to the culture. A wide range of bacteria will grow on Nutrient Agar (item #821862) and Tryptic Soy Agar (item #822022).

Can I pour my own plates if I don’t have an autoclave?
See our Nutrient Agar Bottle (item #776360) and other prepared media bottles. A bottle containing 125 mL of medium will pour 4 to 5 standard 100 × 15-mm plates. Watch our “How to Melt and Pour Agar Plates” video (at www.carolina.com) for a demonstration of the technique.
Should I order a tube, plate, or MicroKwik Culture®?
Tube cultures are best for stock. A tube culture is often streaked on a plate and incubated before lab use. Order a plate culture for convenience and immediate use. You can receive a plate culture and use it in a lab on the same day. A MicroKwik Culture® is best used for longer-term storage and to receive a culture of a pathogen. A MicroKwik Culture® can be held at room temperature for up to 2 months before being activated or for 6 to 8 months refrigerated.

Which cultures should I order for antibiotic testing?
Gram-positive and Gram-negative bacteria often give different results when tested against the same antibiotic. For that reason, we recommend testing against Bacillus cereus (item #154872), which is Gram-positive, and Escherichia coli (item #155068), which is Gram-negative. We recommend broth cultures because this makes it easier to spread the culture over the surface of an agar plate. See our Carolina BioKits®: Antibiotic Sensitivity kit (item #154740) for more information.
You recommend holding a culture at room temperature, but the recommended temperature for Escherichia coli (item #155065) is given in your catalog as 37° C. Why is that?
Thirty-seven degrees C is the incubation temperature, the temperature needed for maximum culture growth. The culture is mature when we ship it out and does not need further incubation. Maintaining the culture at room temperature allows you to hold it longer before use.
